Technology within medicine has great potential to bring about more accessible, efficient, and a higher quality delivery of care. Paediatric supracondylar fractures are the most common elbow fracture in children and at our institution often have high rates of unnecessary long term clinical follow-up, leading to an inefficient use of healthcare and patient resources. This study aims to evaluate patient and clinical factors that significantly predict necessity for further clinical visits following closed reduction and percutaneous pinning. A total of 246 children who underwent closed reduction and percutaneous pinning following supracondylar humerus fractures were prospectively enrolled over a two year period. Patient demographics, perioperative course, goniometric measurements, functional outcome measures, clinical assessment and decision making for further follow up were assessed. Categorical and continuous variables were analyzed and screened for significance via bivariate regression. Significant covariates were used to develop a predictive model through multivariate logistical regression. A probability cut-off was determined on the Receiver Operator Characteristic (ROC) curve using the Youden index to maximize sensitivity and specificity. The regression model performance was then prospectively tested against 22 patients in a blind comparison to evaluate accuracy. 246 paediatrics patients were collected, with 29 cases requiring further follow up past the three month visit. Significant predictive factors for follow up were residual nerve palsy (p < 0 .001) and maximum active flexion angle of injured elbow (p < 0 .001). Insignificant factors included other goniometric measures, subjective evaluations, and functional outcomes scores. The probability of requiring further clinical follow up at the 3 month post-op point can be estimated with the equation: logit(follow-up) = 11.319 + 5.518(nerve palsy) − 0.108(maximum active flexion). Goodness of fit of the model was verified with Nagelkerke R2 = 0.574 and Hosmer & Lemeshow chi-square (p = 0.739). Area Under Curve of the ROC curve was C = 0.919 (SE = 0.035, 95% CI 0.850 – 0.988). Using Youden's Index, a cut-off for probability of follow up was set at 0.094 with the overall sensitivity and specificity maximized to 86.2% and 88% respectively. Using this model and cohort, 194 three month clinic visits would have been deemed medically unnecessary. Preliminary blind prospective testing against the 22 patient cohort demonstrates a model sensitivity and specificity at 100% and 75% respectively, correctly deeming 15 visits unnecessary. Virtual clinics and automated clinical decision making can improve healthcare inefficiencies, unclog clinic wait times, and ultimately enhance quality of care delivery. Our regression model is highly accurate in determining medical necessity for physician examination at the three month visit following supracondylar fracture closed reduction and percutaneous pinning. When applied correctly, there is potential for significant reductions in health care expenditures and in the economic burden on patient families by removing unnecessary visits. In light of positive patient and family receptiveness toward technology, our promising findings and predictive model may pave the way for remote health care delivery, virtual clinics, and automated clinical decision making

Paediatric supracondylar fractures are the most common elbow fracture in children, and is associated with an 11% incidence of neurologic injury. The goal of this study is to investigate the natural history and outcome of motor nerve recovery following closed reduction and percutaneous pinning of this injury. A total of 246 children who underwent closed reduction and percutaneous pinning following supracondylar humerus fractures were prospectively enrolled over a two year period. Patient demographics (age, weight), Gartland fracture classification, and associated traumatic neurologic injury were collected and analyzed with descriptive statistics. Patients with neurologic palsies were separated based on nerve injury distribution, and followed long term to monitor for neurologic recovery at set time points for follow up. Of the 246 patient cohort, 46 patients (18.6%) sustained a motor nerve palsy (Group 1) and 200 patients (82.4%) did not (Group 2) following elbow injury. Forty three cases involved one nerve palsy, and three cases involved two nerve palsies. No differences were found between patient age (Group 1 – 6.6 years old, Group 2 – 6.2 years old, p = 0.11) or weight (Group 1 – 24.3kg, Group 2 – 24.5kg, p = 0.44). A significantly higher proportion of Gartland type III and IV injuries were found in those with nerve palsies (Group 1 – 93.5%, Group 2 – 59%, p < 0 .001). Thirty four Anterior Interosseous Nerve (AIN) palsies were observed, of which 22 (64.7%) made a full recovery by three month. Refractory AIN injuries requiring longer than three month recovered on average 6.8 months post injury. Ten Posterior Interosseous Nerve (PIN) palsies occurred, of which four (40%) made full recovery at three month. Refractory PIN injuries requiring longer than three month recovered on average 8.4 months post injury. Six ulnar nerve motor palsies occurred, of which zero (0%) made full recovery at three month. Ulnar nerve injuries recovered on average 5.8 months post injury. Neurologic injury occurs significantly higher in Gartland type III and IV paediatric supracondylar fractures. AIN palsies remain the most common, with an expected 65% chance of full recovery by three month. 40% of all PIN palsies are expected to fully recover by three month. Ulnar motor nerve palsies were slowest to recover at 0% by the three month mark, and had an average recovery time of approximately 5.8 months. Our study findings provide further evidence for setting clinical and parental expectations following neurologic injury in paediatric supracondylar elbow fractures

To compare the clinical and radiographic outcomes of Type III supracondylar fractures of the humerus in children managed either by open reduction and internal fixation versus those treated by closed reduction and percutaneous pinning. The indications for open reduction included an inability to obtain a satisfactory reduction by closed means; open fractures and fractures with vascular compromise after closed reduction. Retrospective chart and radiograph review over a ten year period (1995–2005), with two hundred and thirty-six children with Type III fractures treated at a Level One pediatric hospital within a universal health-care system. One hundred and seventy by closed reduction and percutaneous pinning and sixty-six by open reduction. The left arm was involved in one hundred and forty-eight cases and twenty-five patients had vascular compromise at presentation but no cases required vascular repair. There were ten open fractures in the open reduction group. The anterior approach was employed in twenty-nine patients, anteromedial in twenty-two and anterolateral, medial and lateral in equal preference. Entrapped structures included brachialis muscle in thirty-four patients, periosteum in eighteen, radial nerve in two, medial nerve in two, and the brachial artery in one. According to Flynn’s criteria, the open reduction group had an excellent or good outcome in 90% of cases while the closed reduction group had an 80% excellent or good outcome. In this study of displaced Type III supracondylar fractures, there was a higher rate of open reduction than was initially anticipated. There was a higher rate of excellent and good outcomes in the ORIF group but this may be due to a relatively short follow-up in the closed reduction group. Post reduction stiffness would likely dissipate and allow a higher rate of excellent and good outcomes in the closed reduction group. An anterior approach or variation of an anterior approach is best suited to visualise the anatomy and structures hindering the reduction. Despite this, there was no clinical or radiographic difference between the approaches employed. In conclusion, open reduction and internal fixation if displaced Type III supracondylar fractures is a safe and effective procedure. An anterior approach is recommended to identify and relieve the soft tissue obstacles to a suitable reduction. Significance: This study furthers the literature that proposes to lower the threshold for open versus closed reduction of displaced supercondylar fractures in children

Aims. We aimed to evaluate the health-related quality of life (HRQoL) in children with supracondylar humeral fractures (SCHFs), who were treated following the recommendations of the Paediatric Comprehensive AO Classification, and to assess if HRQoL was associated with AO fracture classification, or fixation with a lateral external fixator compared with closed reduction and percutaneous pinning (CRPP). Methods. We were able to follow-up on 775 patients (395 girls, 380 boys) who sustained a SCHF from 2004 to 2017. Patients completed questionnaires including the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH; primary outcome), and the Pediatric Quality of Life Inventory (PedsQL). Results. An AO type I SCHF was most frequent (327 children; type II: 143; type III: 150; type IV: 155 children). All children with type I fractures were treated nonoperatively. Two children with a type II fracture, 136 with a type III fracture, and 141 children with a type IV fracture underwent CRPP. In the remaining 27 children with type III or IV fractures, a lateral external fixator was necessary for closed reduction. There were no open reductions. After a mean follow-up of 6.3 years (SD 3.7), patients with a type I fracture had a mean QuickDASH of 2.0 (SD 5.2), at a scale of 0 to 100, with lower values representing better HRQoL (type II: 2.8 (SD 10.7); type III: 3.3 (SD 8.0); type IV: 1.8 (SD 4.6)). The mean function score of the PedsQL ranged from 97.4 (SD 8.0) for type I to 96.1 (SD 9.1) for type III fractures, at a scale of 0 to 100, with higher values representing better HRQoL. Conclusion. In this cohort of 775 patients in whom nonoperative treatment was chosen for AO type I and II fractures and CRPP or a lateral external fixator was used in AO type III and IV fractures, there was equally excellent mid- and long-term HRQoL when assessed by the QuickDASH and PedsQL. These results indicate that the treatment protocol followed in this study is unambiguous, avoids open reductions, and is associated with excellent treatment outcomes.

This study aimed to evaluate the use of pin leverage in the reduction of Gartland type III supracondylar fractures of the humerus in children. The study comprised 95 children, who were split into three groups according to the type of method of reduction used. Group 1, had an open reduction, group 2, had closed reduction and percutaneous pin fixation and group 3, the pin leverage technique. Each group was analysed according to the time to surgery, the duration of the procedure, the incidence of complications, and the clinical and radiological outcome. The mean duration of the operative procedure in groups 1, 2 and 3 was 119 minutes (80 to 235), 57 minutes (20 to 110) and 68 minutes (30 to 90), respectively. At a mean follow-up of 30 months (12 to 63) the clinical results were declared excellent or good in all children and the radiological results intermediate in five patients in group 2. The results of the closed reduction using the pin leverage technique was classified as failure in two children. Our findings lead us to believe that the pin leverage method of reduction gives good results in the treatment of Gartland type III fractures

The Gartland extension-type supracondylar humerus fracture is the most common elbow fracture in the paediatric population. Depending on fracture classification, treatment options range from nonoperative treatment such as taping, splinting or casting to operative treatments such as closed reduction and percutaneous pinning or open reduction. Classification variability between surgeons is a potential contributing factor to existing controversy over nonoperative versus operative treatment for Type II supracondylar fractures. The purpose of this study was to investigate levels of agreement in classification of extension-type supracondylar humerus fractures using the Gartland classification system. A retrospective chart review was conducted on patients aged 2–12 years who had sustained an extension-type supracondylar fracture and received either operative or nonoperative treatment at a tertiary children's hospital. De-identified baseline anteroposterior (AP) and lateral plain elbow radiographs were provided along with a brief summary of the modified Gartland classification system to surgeons across Canada, United States, Australia, United Kingdom and India. Each surgeon was blinded to patient treatment and asked to classify the fractures as Type I, IIA, IIB or III according to the classification system provided. A total of 21 paediatric orthopaedic surgeons completed one round of classification, of these, 15 completed a second round using the same radiographs in a reshuffled order. Kappa values using pre-determined weighted kappa coefficients were calculated to assess interobserver and intraobserver levels of agreement. In total, 60 sets of baseline elbow radiographs were provided to survey respondents. Interobserver agreement for classification based on the Gartland criteria between surgeons was a mean of 0.68, 95% CI [0.67, 0.69] (0.61–0.80 considered substantial agreement). Intraobserver agreement was a mean of 0.80 [0.75, 0.84]. (0.61–0.80 substantial agreement, 0.81–1 almost perfect agreement). Radiographic classification of extension-type supracondylar humerus fractures at baseline demonstrated substantial agreement both between and within surgeon raters. Levels of agreement are substantial enough to suggest that classification variability is not a major contributing factor to variability in treatment between surgeons for Type II supracondylar fractures. Further research is needed to compare patient outcomes between nonoperative and operative treatment for these fractures, so as to establish consensus and a standardized treatment protocol for optimal patient care across centres

Introduction: Closed reduction and percutaneous pinning techniques for displaced supracondylar fractures of the humerus in children have overcome disastrous ischemic complications and long inpatient treatment. Closed reduction of those highly unstable fractures and the demanding pin placement itself are potential sources of failure for the inexperienced reflected by the rate of cubitus varus which is still about 5 to 15% in recent series. Rotational primary and residual displacement has to be appreciated to prevent permanent cosmetic deformity. Malrotation is the major source of instability since bicolumnar support is lost which allows the distal fragment to tilt. Anatomy: The transverse section of the distal humerus is the key to all stability related problems faced in supra-condylar fractures of the humerus in children. In the supracondylar region the radial and ulnar column are only connected by a thin bony wafer which results from the presence of the cubital and olecranon fossa. In case of a fracture. In case of a fracture rotation leads to decrease of bony contact and hence to instability. Epidemiology: Elbow fractures account for 7–10% of all pediatric fractures whereof 80–90% are located at the distal humerus with 80% involvement of the supracondylar region. Most of the supracondylar fractures occur between ages 5 and 10 years. Mechanism of injury: Fall from a height, usually from a household object in the age group < 3 years or from a playground equipment in children > 4 years on the outstretched nondominant arm (indirect elbow trauma). 96% of all supracondylar fractures are extension type injuries. Open fractures, mostly grade 1, occur when the anterior spike of the proximal fragment pierces through the brachialis muscle and the skin of the cubital fossa. Their incidence is about 1–3% in major referral centers. Differential diagnosis: Supracondylar fractures have to be differentiated from transcondylar fractures and dislocations of the elbow. In a supracondylar fracture the fracture line stays proximal to the distal humerus physis. If it runs across it, it is most likely a supracondylar fracture. Dislocations of the elbow typically after the age of 10 years. Neurologic compromise: Fracture related peripheral neuropathies have an incidence of 10 to 17%. With rare exceptions concomitant nerve lesion recover spontaneously within a time range of 1 to 4 months. The rate of iatrogenic nerve injuries is 3%–16% with the ulnar nerve being the most susceptible due to inadvertent pinning. Despite a high recovery rate, they are a nuisance for the patients. Vascular compromise: Early recognition of vascular compromise with subsequent reduction and fixation of the fracture and avoidance of extreme flexion at the elbow have decreased the incidence of ischemic complications. An initially absent radial pulse is found in up to 19% in displaced fractures. Closed reduction restores pulsation in about 80%. Patients with postreduction lack of pulse or poor capillary refill should undergo vascular revision. There is still controversy regarding the management of a post reduction pink, warm but pulse less hand with adequate capillary refill. Simple observation and conservative management leads to a favourable clinical outcome in most cases but cold intolerance or exercise induced ischemic symptoms is a potential sequel. Treatment:. Undisplaced fractures: simple immobilisation e.g. collar and cuff. Incomplete displacement: in case of malrotation and/or age-related unacceptable extension (> 20° in patients older than 6 years) closed reduction and pinning otherwise conservative management. Complete displacement: Attempt for closed reduction and percutaneous pinning. Irreducibility is found in up to 22%. Open reduction is most widely as a last resort. Complications:. Infection. Occasionally, superficial infection after pinning occurs despite all preventive measure (wires left protruding through the skin should not be covered by plaster to prevent rubbing; pin care instruction for the parents; regular follow-up for pin site inspection). Cubitus varus. Most common complication with an overall incidence of about 20%. As a malunion in the coronal plane it has no capacity for remodelling. Although this deformity is mainly a cosmetic problem and does not interfere with the range of motion, it may be a functional problem in some activities e.g. in apparatus gymnastics. Malunion/Stiffness. Even after perfect reduction, lack of full extension is common and usually takes over 6 months to improve. Impaired range of motion may be prolonged or even persistent due to an underlying pathology. Malunion is the most common one. In the sagittal plane, antecurvation leads to hyperextension and reduced flexion of the elbow. Significant remodelling with growth can only be expected below the age of 6 and in antecurvations of less than 20°. Rotatory malunion with an anterior spur restrains flexion. Complete remodelling of the spur usually takes place even in older children. Volkmann’s contracture represents the most severe complication after supracondylar fractures. Fortunately, it has become a rarity. Conclusion:. The human factor, in view of the particular anatomy of the supracondylar region and the extreme fracture instability seems to be more decisive for the end result than any biomechanical differences of various pin configurations. Repeat instruction by an experienced surgeon for proper reduction technique, assessment of achieved reduction and technically correct pin placement is crucial to further improve the outcome of this challenging fracture

The management of an anterior supracondylar fracture by closed reduction, traction, percutaneous pinning or open reduction is seldom satisfactory, especially for adults and the aged with a lesser ability to remodel and a slower functional recovery. A new, safe, and simple technique is described in which the condylar mass is pushed posteriorly along the axis of the forearm and the hand is rotated to full supination while the elbow is held in flexion to correct deformities. Fixation is divided into two parts: the circular cast around the upper arm provides a firm buttress onto which the lower fragment is reduced and then the arm is immobilised in a plaster which includes the wrist. Four cases of delayed, comminuted, compound fractures have been fully evaluated clinically and radiologically and the results assessed as good or excellent

Closed reduction and percutaneous pinning has become the most common technique for the treatment of Type III displaced supracondylar humerus fractures in children. The purpose of this study was to evaluate whether the loss of reduction in lateral K wiring is non-inferior to crossed K wiring in this procedure. A prospective randomised non-inferiority trial was conducted. Patients aged three to seven presenting to the Emergency Department with a diagnosis of Type III supracondylar humerus fracture were eligible for inclusion in the study. Consenting patients were block randomised into one of two groups based on wire configuration (lateral or crossed K wires). Surgical technique and post-operative management were standardised between the two groups. The primary outcome was loss of reduction, measured by the change in Baumann's angle immediately post –operation compared to that at the time of K wire removal at three weeks. Secondary outcome data collected included Flynn's elbow score, the humero-capitellar angle, and evidence of iatrogenic ulnar nerve injury. Data was analysed using a t-test for independent means. A total of 52 patients were enrolled at baseline with 23 allocated to the lateral pinning group (44%) and 29 to the cross pinning group (56%). Six patients (5 crossed, 1 lateral) received a third wire and one patient (crossed) did not return for x-rays at pin removal and were therefore excluded from analysis. A total of 45 patients were subsequently analysed (22 lateral and 23 crossed). The mean change in Baumann's angle was 1.05 degrees, 95% CI [-0.29, 2.38] for the lateral group and 0.13 degrees, 95% CI [-1.30, 1.56] for the crossed group. There was no significant difference between the groups in change in Baumann's Angle at the time of pin removal (p = 0.18). Two patients in the crossed group developed post-operative iatrogenic ulnar nerve injuries, while none were reported in the lateral group. Preliminary analysis shows that loss of reduction in Baumann's angle with lateral K wires is not inferior to crossed K wires in the management of Type III supracondylar humerus fractures in children. The results of this study suggest that orthopaedic surgeons who currently use crossed K wires could consider switching to lateral K wires in order to reduce the risk of iatrogenic ulnar nerve injuries without significantly compromising reduction

Introduction: Treatment of proximal humeral fractures is still controversial. Conservative treatment may result in malunion and shoulder stiffness. We present our experience with displaced or comminuted fractures of the proximal humerus treated by closed or open “minimal invasive osteosynthesis” or by open reduction and using of fixed plates or by hemiarthroplasty. Patients and Methods: This study consists of 189 Pts. (18–89 year old, mean 58.5Y) followed for 2–10 years (mean 5.5Y), treated by closed reduction and percutaneous pinning (79), ORIF and minimal osteosynthesis (27), ORIF with rigid plates (17), ORIF by LCP plates (10), ORIF by proximal humeral nail (5) or by hemiarthroplasty (51). Patients were evaluated by the UCLH and by Constant’s shoulder grading score systems and radiographs. Results: Overall results were excellent and good in 85% of patients with 2 and 3 parts fractures of the proximal humerus treated by “minimal osteosynthesis” techniques, with some better results in less comminuted fractures. 26/32 Pts with 4 part fractures treated surgically had good functional results. The other 8 had poor results and 4 of them developed AVN of the humeral head. 75% of the patients treated by hemiarthroplasty had satisfactory results. They were almost free of pain, but had only a moderate improvement in shoulder motion (active abduction or flexion of 30–90 degrees in 38/51). Conclusions: “Minimal osteosynthesis” by K.W. techniques, lag screws, rush pins or proximal humeral nail, by closed or open reduction, remains as the first optional treatment of complex fractures of the shoulder, even in young patients with a 4 part fracture. ORIF by conventional plates may be used in young patients and by LCP (locked compression plates) in osteoporotic or comminuted fractures of older patients. In the elderly, hemiarthroplasty seems to be the treatment of choice

Introduction: Traumatic and iatropathic nerve injuries complicate 6–16% of paediatric supracondylar extension fractures of the humerus. The majority recover spontaneously. This retrospective review of lesions referred to our tertiary unit determined the incidence of surgical intervention. Methods: Between 1997–2002, 37 neuropathies (32 fractures) in 19 males and 13 females (mean age 7.9yrs) were referred for further management. 8 fractures were Gartland grade 2 and 24 grade 3. All fractures were closed. Two were originally treated non-operatively, 20 by closed reduction and percutaneous pinning and 10 by open reduction and internal fixation. Results: The ulnar nerve was most frequently injured (19, 51.4%), followed by median (10, 27%) and radial (8, 21.6%) nerve palsies. 14 (37.8%) neuropathies were fracture-related but 23 (62.2%) were treatment-related. 10 patients (31.3%) required operative exploration. Three (9.4%) were listed for surgery but cancelled due to nerve recovery. Nerve grafting using either the forearm medial cutaneous nerve or the superficial radial nerve was necessary in 4 of 10 operated cases. 26 patients (81.3%) had excellent outcomes, 5 (15.6%) good and 1 (3.1%) fair. Discussion: In contrast to current literature suggesting that 86 to 100% of supracondylar associated neuropathies recover spontaneously within 2 to 3 months, surgical exploration was required in over 30% of cases

Aims. Comparison of the outcome between the supine or prone positioned child with a supracondylar humerus fracture by measuring anaesthetic and operating time, functional outcomes and complications. Methods. All children with isolated Gartland 2 and 3 supracondylar humerus fractures were who were admitted to our institute, were asked to participate in the the study. For surgery, the participating children were either operated on in a ‘supine’ or ‘prone’ position. The children were randomly allocated to either the ‘supine’ or ‘prone’ position. The fractures were preferably treated by closed reduction and percutaneous pinning with k-wires. However, if the fracture proved difficult to reduce, we proceeded to open reduction via medial and lateral approach. All fractures were stabilized with one medial and one lateral k-wire. The children were immobilized in a reinforced above elbow back-slab. Total anaesthetic and surgical time were meticulously recorded. Patients were followed up in our outpatient clinic at one week, four weeks (at which time the k-wires were removed). Three months post operatively, elbow extension, flexion and total range of movement was assessed in all children. Results Twenty children with isolated Gartland 2 and 3 supracondylar humerus fractures were included in this study. Nine children (5 ± 1 years, 7 boys and 2 girls) were operated on in a prone position, while 11 children (6 ± 2 years, 10 boys and 1 girls) were operated on in a supine position. Results. The anaesthetic time was significantly longer in the prone (20 ± 8 min) than in the supine position(10 ± 3 min) (p = 0.001). In line with this, surgical time showed a tendency to also be longer in prone (44 ± 36 min) than supine position (18 ± 18 min) (p = 0.08). No differences between prone and supine operated children was found for elbow extension (4.4 ± 7.7° vs. 3.6 ± 7.1°, respectively (p = 0.81)), elbow flexion (129.4 ± 8.8° vs. 127.0 ±8.8°, respectively (p = 0.67)) and/ or elbow range of motion (125.0 ± 16.0° vs. 124.1 ± 14.6°, respectively (p = 0.90)). Conclusion. As no differences were found in elbow mobility 3 months post-operatively and anesthetic and surgical time tends to be longer in a prone position, this study suggests that operating children with Gartland 2 and 3 supracondylar humerus fractures in a supine position is more favorable. NO DISCLOSURES

Objective: The reported incidences of traumatic and iatropathic nerve injuries with supracondylar fractures in children are 12–16% and 6% respectively, with the majority recovering spontaneously. We performed a retrospective review of lesions referred to our tertiary unit to determine the incidence of surgical intervention. Methods: Between 1997 and 2002, 37 neuropathies (associated with 32 supracondylar fractures) in 19 males and 13 females with an average age of 7.9 years were referred for further management. 8 fractures were classified as Gartland grade 2 and 24 as grade 3. All fractures were closed, with 2 treated non-operatively, 20 by closed reduction and percutaneous pinning and 10 by open reduction and internal fixation at the referring hospitals. Results: The ulnar nerve was the most frequently injured (51.4%), followed by median (27%) and radial (21.6%) nerve palsies. 14 (37.8%) neuropathies were related to the fracture, while 23 (62.2%) were iatropathic. 10 patients (31.3%) required operative exploration while 3 (9.4%) were listed for surgery but were cancelled as they were recovering. Nerve grafting was used in 4 of the 10 operated cases, the donor nerve being the medial cutaneous nerve of the forearm in 3 and the superficial radial nerve in one. 26 patients (81.3%) had excellent outcomes, 5 (15.6%) good and 1 (3.1%) fair. Conclusion: Although most had excellent outcomes, surgical exploration was required for nearly a third of the cases referred to our unit. This is in contrast to the current literature, which suggests that the majority of supracondylar neuropathies recover spontaneously

Introduction: The treatment of fractures of the proximal humerus is still controversial. Conservative treatment may result in severe disability due to malunion and shoulder stiffness. Open reduction and rigid fixation requires extensive soft tissue exposure, which may results in a high incidence of avascular necrosis of the proximal humerus. We present our experience with “minimal invasive” surgical techniques of such fractures. Materials & Methods: This study consists of 128 Pts. (52 M, 76 F, 18–84 year old, mean 53.5Y) followed for 2–7 years (mean 3.5Y), treated by closed reduction and percutaneous pinning (55), by ORIF and minimal osteosynthesis by screws (27), by ORIF with rigid plates (7), and by hemiarthroplasty of the proximal humerus (39). Patients were evaluated by the Neer’s shoulder grading score and radiographs. Results: Overall results were excellent and good in 85% of patients with 2, and 3 parts fractures of the proximal humerus treated by “minimal invasive” fixation techniques, with some better results in less comminuted fractures. 9/14 young patients with 4 part fractures had good functional results. The other 5 patients had poor results and 3 of them developed AVN of the humeral head. 75% of the patients treated by hemiarthroplasty had satisfactory results. They were almost free of pain, but most of them had only a moderate improvement in shoulder motion. Discussion: Based on this study it seems that “minimal osteosynthesis” by K.W. techniques, lag screws or rush pins, by closed or open reduction, remains as the first optional treatment of complex fractures of the shoulder, even in young patients with a 4 part fracture. In the elderly, hemiarthroplasty should be considered in such pathology as the treatment of choice

Introduction: The preferred treatment for displaced supracondylar humeral fractures in children is closed reduction and percutaneous pinning. Cross-wiring techniques are biomechanically superior to parallel lateral wiring techniques. The purpose of this study was to review our experience with a novel cross wiring technique performed entirely from the lateral side. This avoids the potential for ulnar nerve injury in these difficult cases. Patients and Methods: We collected all children with supracondylar fractures of the distal humerus who were manipulated and wired by one surgeon, using a lateral cross wiring technique. Patient demographics, mechanism of injury, fracture classification (Gartland’s classification) and associated neurovascular injuries were noted. At follow-up (12 weeks), range of motion and carrying angle were measured. Results: Twenty patients were identified and reviewed. There were 8 female and 14 male patients, mean age 10 years (range 2–11). Two fractures were Type II, 12 were Type IIIA and 6 were Type IIIB. Three patients had signs of an anterior interosseous nerve injury and one patient had a brachial artery laceration. All fractures were reduced, cross-wired from the lateral side, and rested in an above elbow slab. Wires were removed at 4 weeks. At follow-up, all children had a full range of motion and the mean carrying angle was 17° (range: 15–20). All three patients with pre-operative nerve injuries had full recovery of nerve function. Conclusions: Lateral cross wiring of supracondylar fractures represents a real option in the treatment of these injuries. It offers the biomechanical advantages of traditional cross-wiring without the risk of nerve injury

Aims

The ‘pink, pulseless hand’ is often used to describe the clinical situation in which a child with a supracondylar fracture of the humerus has normal distal perfusion in the absence of a palpable peripheral pulse. The management guidelines are based on the assessment of perfusion, which is difficult to undertake and poorly evaluated objectively. The aim of this study was to review the available literature in order to explore the techniques available for the preoperative clinical assessment of perfusion in these patients and to evaluate the clinical implications.

Purpose: The treatment algorithm for supracondylar humerus fractures in children under age seven is well-established. However, the best treatment option for these fractures in older children (8–14 year olds) is debated. The purpose of this study was to assess the efficacy of closed versus open fixation methods of this fracture type in older children. We hypothesize that closed reduction and percutaneous pinning (CRPP) is as effective as open reduction and internal fixation (ORIF). Method: A retrospective chart review was completed of all patients 8–14 years old treated for supracondylar humerus fractures at one centre from 2000–2007. IRB approval was obtained for this study. Demographics, treatment methods, pre- and post-operative complications, functional and radiographic outcomes were reviewed. Values are reported as mean ± standard deviation. Results: Seventy-eight eligible patients were identified: 60 (76.9%) were treated with CRPP, and 18 (23.1%) were treated with ORIF. Demographics and fracture characteristics were similar between the CRPP and ORIF groups, although patients treated with ORIF were older (p< 0.001) and weighed more (p< 0.001). The ORIF group had higher post-operative complication rates (p=0.016). Five patients treated with CRPP required additional surgery (3 underwent ORIF; 2 underwent repeat CRPP) compared with none in the ORIF group. Children treated with ORIF had greater limitations on active flexion (99.7o ± 18.2 ORIF, 140.5o ± 23.5 CRPP, p< 0.001) and active extension (34.3o ± 19.0 ORIF, 11.9o ± 21.2 CRPP, p< 0.001) at first follow-up. Limitations in active flexion persisted in the ORIF group, but not in the CRPP group, at time of last follow-up (120o ± 14.8 versus 150.4o ± 17.8, p< 0.001). There were no group differences in active extension at last follow-up (p=0.093). On radiographs, significant differences between the groups existed for Bauman’s angles (15.5o ± 5.5 ORIF, 19.3o ± 4.9 CRPP, p=0.013) and carrying angle (12.4o ± 5.7 ORIF, 16.6o ± 5.4 CRPP, p=0.008). Radiographic union was achieved in all cases. Conclusion: Open and closed surgical fixation are both acceptable treatment options for supracondylar humerus fracture in older children. While ORIF appears to result in reduced range of motion, no further operations were required for fracture alignment in this group

Introduction: The treatment of fractures of the proximal humerus is still controversial. Conservative treatment may result in severe disability due to malunion and shoulder stiffness. Open reduction and rigid fixation requires extensive soft tissue exposure, which may result in a high incidence of avascular necrosis of the proximal humerus. Today, many authors are in the opinion that “minimal osteosynthesis” of such fractures is preferable to rigid fixation. It may be achieved by K.W. techniques, lag screws, rush pins, percutaneous pinning or percutaneous external fixation. This study reviews our experience with comminuted fractures of the proximal humerus treated by different minimal invasive techniques of fixation, using functional evaluation and radiological assessment. Materials and methods: This study consists of 76 patients with comminuted fractures of the proximal humerus (33 M, 44 F, 18–89 year old, mean 52/5Y) with follow-up of 2–6 years (mean 3.5Y). They were treated by minimal invasive surgical techniques: 53 of them by closed reduction and percutaneous pinning and the remaining 23 by ORIF and minimal osteosynthesis. All patients were evaluated by Neer’s shoulder grading score and radiographs. Results: Overall results were excellent and good in 85% of patients with 2, and 3 parts fractures of the proximal humerus, treated either by closed or open minimal osteosynthesis techniques, with some better results in less comminuted fractures. 9/13 (69%) of young patients with 4 part fractures treated by closed percutaneous minimal fixation had good functional results. In four other patients the clinical results were poor and two of them developed AVN of the humeral head. 5/8 (62.5%) of young patients with 4 part fractures treated by ORIF and minimal fixation had good functional results. In three other patients the clinical results were poor and one of them developed AVN of the humeral head. Conclusions: Based on this study it seems that “minimal osteosynthesis” by K.W. techniques and by lag screws, by closed or open reduction, remains as the first optional treatment of complex fractures of the shoulder, even in young patients with a 4 part fracture
