Aims. Our objective was describing an algorithm to identify and prevent vascular injury in patients with intrapelvic components. Methods. Patients were defined as at risk to vascular injuries when components or cement migrated 5 mm or more beyond the ilioischial line in any of the pelvic incidences (anteroposterior and Judet view). In those patients, a serial investigation was initiated by a CT angiography, followed by a vascular surgeon evaluation. The investigation proceeded if necessary. The main goal was to assure a safe tissue plane between the hardware and the vessels. Results. In ten at-risk patients undergoing revision hip arthroplasty and submitted to our algorithm, six were recognized as being high risk to vascular injury during surgery. In those six high-risk patients, a preventive preoperative stent was implanted before the orthopaedic procedure. Four patients needed a second reinforcing stent to protect and to maintain the vessel anatomy deformed by the intrapelvic implants. Conclusion. The evaluation algorithm was useful to avoid blood vessels injury during revision total hip arthroplasty in high-risk patients. Cite this article: Bone Jt Open 2022;3(11):859–866

Orthopaedic injuries in the knee are often associated with vascular injury. When these vascular injuries are missed devastating there are devastating outcomes like limb ablation. Pulse examination in these patients is not sensitive to exclude vascular injuries. That often lead to clinicians opting for Computed Tomography Angiogram (CTA) to exclude vascular. this usually leads to a burden in Radiology Department. This study aimed to evaluate the prevalence of vascular injury in patient with orthopaedic injury in the knee. The computed tomography (CT) done in patients with distal femur fracture, knee dislocation and proximal tibia fractures were retrieved from the picture archiving and comunication system (PACS). The CTs were done between June 2017 and June 2022. The computed tomography angiogram (CTA) reports were reviewed to determine cases that vascular injury. A sample size of 511 cases was collected. 386 cases were done CTA and 125 cases were not done CTA. There were 218 tibial plateau fractures, 79 knee dislocations, 72 distal metaphyseal femur fractures, 61 floating knees, 55 distal femure intraarticular and 26 proximal metaphyseal tibia fractures. The mechanisms of injury in these were gunshot, fall from standing height, fall from height, MVA, MBA, PVA and sports. Prevalance was 9.17% (47) of the total injuries in the knee. Prevalance in patients who were sent for CTA was 12.08%. Routine CTA in patients with injuries in the knee is not recomended. The use of ankle brachial index may decrease the number of CTA done

Background: Vascular injuries associated with total joint arthroplasty are the most feared complication. The arterial and venous injury can occur due to direct or indirect trauma. A high index of suspicion, recognition of the injury and prompt treatment, with the immediate availability of a vascular surgeon is vital for good outcome. Methods: Using prospectively collected data on 13624 patients undergoing total joint arthroplasty at our institution, all incidences of vascular injury were identified. Detailed data regarding the mode of presentation, the type and the outcome of intervention delivered, and the eventual functional outcome of the total joint arthroplasty were determined. Results: There were a total of 17 vascular injuries (0.1%). Majority (16/17) of these vascular injuries were detected in the postoperative recovery area. 9 injuries occurred after TKA and 8 occurred after THA. Indirect injury was the mechanism in TKA patients with popliteal artery thrombosis being the mechanism. In contrast direct injury was the mechanism in THA patients. Fasciotomy was performed in all TKA patients and none were needed in the THA patients. One patient died of complications related to vascular injury. 12 of 17 patients (70%) had launched a legal suit against the operating surgeon. Conclusions: After more than 80 years of accumulated experience and more than 35000 joint replacements performed by 5 surgeons in our center, the vascular complication still continues to occur. Patient awareness regarding this real problem may play a role in defraying the extremely high likelihood of legal suits associated with this complication

Purpose of the study: Elbow dislocation is a frequent traumatic injury. Management is well described. An associated vascular lesion is exceptional, but must be searched for systematically. We report a short series and describe our therapeutic strategy for these complicated dislocations. Material and methods: Between 1999 and 2004, our emergency unit cared for 357 cases of elbow dislocation. For six, injury to the brachial artery was present. This series included four men and one woman, mean age 34.7 years. The causal trauma was a traffic accident for four, and a fall four two. The dislocation was open in three. The radial pulse could not be palpated in any of the patients but blood supply to the hand persisted in five. There was a clinically detected neurological deficit in three. After obtaining the necessary x-rays, the elbows were reduced in the emergency room. The radial pulse remained impalpable in all patients and arteriography was performed and revealed a rupture of the brachial artery in five and an arterial spasm in one. Vascular repair was undertaken in all six cases using an reversed venous graft. The elbow was stabilized with an external fixator in three patients. For the others, the elbow was immobilized for 21 days on average before remobilization. Results: AT 23 months follow-up, the overall outcome has been average with a Mayo clinic score of 69.2 points. Only four elbows were functional. Only one patient had a pain free elbow. Stiff joint was the most frequent functional impairment: mean flexion was 111.7° with a 41.7° extension deficit. The blood supply to the hand was correct in all cases, but one of the graft bridges became obstructed by a thrombus, the distal vascularization being supplied by the collateral circulation. The initial neurological lesions recovered partially. Discussion: Elbow dislocation with vascular injury is exceptional but must be systematically detected. Emergency management associates reduction of the dislocation, a vascular work-up and rapid surgical management of the elbow, using an articulated external fixator when necessary, to limit as much as possible posttraumatic stiffness

Introduction. Knee dislocations, vascular injuries and floating knee injuries can be initially managed by a external fixator. Fixator design constructs include the AO pattern and the Diamond pattern. However, these traditional constructs do not adhere to basic principles of external fixation. The Manchester pattern knee-spanning external fixator is a new construct pattern, which uses beam loading and multiplanar fixation. There is no data on any construct pattern. This study compares the stability of these designs. Materials & Methods. Hoffman III (Stryker, USA) external fixation constructs were applied to articulated models of the lower limb, spanning the knee with a diamond pattern and a Manchester pattern. The stiffness was loaded both statically and cyclically with a Bose 3510 Electroforce mechanical testing jig (TA Instruments). A ramp to load test was performed initially and cyclical loading for measurement of stiffness over the test period. The results were analysed with a paired t-test and ANOVA. Results. The mean stiffness with the diamond pattern fixator was significantly less stiff than the Manchester pattern fixator – by a factor of 3 (40N/mm vs 115N/mm). Displacement increased in all patterns over simulated loading equating to six weeks. The diamond pattern demonstrated a 50%% increase in displacement over time. The Manchester pattern demonstrated only 20% increase in displacement over time. These are all statistically significant (p<0.01). Conclusions. The aim of an external fixator in knee dislocations and vascular injuries is to provide stability, prevent displacement and protect repairs. Vascular injuries often require fixation for several weeks to protect a repair. The Manchester pattern, applying the principles of external fixation, provides a stiffer construct and also confers greater stability over the time a fixator may be required. We commend this more informed design for the management of knee dislocations and vascular injuries

Abstract. Introduction. Knee dislocations (KDs) are complex injuries which are often associated with damage to surrounding soft tissues or neurovascular structures. A classification system for these injuries should be simple and reproducible and allow communication among surgeons for surgical planning and outcome prediction. The aim of this study was to formulate a list of factors, prioritised by high-volume knee surgeons, that should be included in a KD classification system. Methods. A global panel of orthopaedic knee surgery specialists participated in a Delphi process. A list of factors to be included in a KD classification system was formulated by 91 orthopaedic surgeons, which was subsequently prioritised by 27 experts from 6 countries. The items were analysed to find factors that had at least 70% consensus for inclusion in a classification system. Results. The four factors that reached consensus agreement and thus deemed critical for inclusion in a classification system were vascular injuries (89%), common peroneal nerve injuries (78%), number of torn ligaments (78%), and open injuries (70%). Conclusion. The wide geographic distribution of participants provides diverse insight and makes the results of the study globally applicable. The most important factors to include in a classification system as determined by the Delphi technique were vascular injuries, common peroneal nerve injuries, number of torn ligaments, and open injuries. The Schenck anatomic classification system most accurately identifies these patient variables with the addition of open injuries. The authors propose to update the Schenck classification system with the inclusion of open injuries as an additional modifier

Abstract. Introduction. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Eighty-seven patients with knee dislocation were treated at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 4 weeks was preferred unless the patient was too unstable (Injury severity score>16). The collaterals were repaired and augmented using a variety of autografts, allografts or synthetic grafts. PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 33.6yrs (SD 11.9), 66 males and 21 females. According to Schenck classification, 26 were KD-I (30%), 6 KD-II (7%), 13 were KD-III (15%), 7 were KD-IV (8%) and 35 were KD-V (40%). 7 patients had CPN injury (8%), 3 had vascular injury (3.4%), 2 had combined CPN and vascular injury (2.3%). Acute surgical treatment was done in 62 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 5.8 years (1- 12 yrs), mean IKDC score was 57.6 (SD 23.6). The mean Tegner activity scale postoperatively was 4.5(SD 2) and the mean KOOS score was 74.9 (SD 19.6). Conclusion. A large proportion of cases were KD-V but still had a good outcome with surgical management. Current classification systems do not cover all dislocation patterns and a modification is proposed

Abstract. Background. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. Treatment needs to be customised to the patient taking into consideration injury to the knee; associated neurovascular and systemic injuries. Objective. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Seventy patients with knee dislocation were treated with multi-ligament reconstruction at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 3 weeks was preferred unless the patient was too unstable (Injury severity score>16). PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 35yrs (17–74), 53 males and 17 females. 5 patients had CPN injury (7%), 3 had vascular injury (4.2%), 2 had combined CPN and vascular injury (2.8%). Acute surgical treatment was done in 48 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 4.8 years (1–12 yrs). According to the IKDC score 67% of the patients had near-normal knee function. The mean Tegner activity scale postoperatively was 4.5 (preinjury 6.5) and the mean KOOS score was 75.3. Four patients had stiffness and needed arthroscopic arthrolysis, two patients had a residual foot drop from the original injury and needed tendon transfer. Conclusion. Traumatic knee dislocation is a challenging problem but good outcomes can be achieved by surgical management

Introduction. Blunt trauma of the lower limb can lead to vascular injury causing devastating outcomes, including loss of limb and even loss of life. The primary aim of this study was to determine the limb salvage rate of patients sustaining such injuries when treated at Leeds General Infirmary (LGI) since becoming a Major Trauma Centre (MTC). Secondary aims included establishing the patient complications and outcomes. Materials and Methods. Retrospective analysis found that from 2013–18, 30 patients, comprising of 32 injured limbs, were treated for blunt trauma to the lower limb associated with vascular injury. Long-term functional outcomes were determined using postal and telephone questionnaires. Results. Twenty-four patients were male and 6 were female, their mean ages were 32 and 49 respectively. Of the 32 limbs, 27 (84%) were salvaged. Three limbs were deemed unsalvageable and underwent primary amputation; of the remaining 29 potentially salvageable limbs, 27 (93%) were saved. Eleven limbs had prophylactic fasciotomies, 3 limbs developed compartment syndrome – all successfully treated, and three contracted deep infections – one of which necessitated amputation. All but 1 patient survived their injuries and were discharged from hospital. Of the 15 questionnaire responses, self-reported limb function was understandably worse post-injury with patients experiencing mild pain on average. In addition, there was a long-standing psychological impact and the injuries altered many patients’ normal lives significantly, 10 experiencing financial difficulties and 6 having changed or lost jobs post-injury. Conclusions. Fortunately, 27 (84%) limbs were salvaged and nearly all patients survived these injuries when treated at an MTC. Whilst the number of complications was low, the future challenges these patients face are wide-ranging and significant

Multiligament knee injuries (MLKI) are associated with significant morbidity and healthcare requirements. The primary aim of this study is to report the patient reported outcomes measures (PROMs) after reconstructive surgery. Patients undergoing surgery for MLKI between 2014 and 2018 in the single large-volume trauma centre were included. Electronic patient records were reviewed for demographic data, details of surgery and complications. PROMs collected were EQ-5D-5L, Lysholm Knee Score (LKS), UCLA Activity and Sport and patient satisfaction. Thirty-five patients were included. Mean age was 31 years (range 16-66), and 71% were male. The most common mechanism of injury was sports-related (71%). Obesity was present in eight (23%) patients. No vascular injuries were recorded and four patients sustained nerve injuries. PROMs were available for 18 patients (51%) with a median follow up of 4.5 years. Median EQ-5D-5L was 0.78 (IQR 0.14). Median LKS was 84.5 (IQR 21) and there was no correlation with time to surgery (p=0.43). Grade of MLKI did not impact LKS (p=0.09). Fifteen patients (83%) saw a reduction in their activity level. All patients were satisfied with their surgical treatment. Recurrent instability was noted in four patients (11%). Three patients (8%) required further surgery (one revision reconstruction, one meniscectomy, one conversion to a hinged knee replacement. This study demonstrates two groups of patients who sustain MLKI: the sporting population and obese patients. Health related quality of life, functional outcomes and satisfaction are high after surgery. Time to surgery did not impact on functional outcomes

Variations in pelvic anatomy are a major risk factor for misplaced percutaneous sacroiliac screws used to treat unstable posterior pelvic ring injuries. A better understanding of pelvic morphology improves preoperative planning and therefore minimises the risk of malpositioned screws, neurological or vascular injuries, failed fixation or malreduction. Hence a classification system which identifies the clinically important anatomical variations of the sacrum would improve communication among pelvic surgeons and inform treatment strategy. 300 Pelvic CT scans from skeletally mature trauma patients that did not have pre-existing posterior pelvic pathology were identified. Axial and coronal transosseous corridor widths at both S1 and S2 were recorded. Additionally, the S1 lateral mass angle were also calculated. Pelvises were classified based upon the sacroiliac joint (SIJ) height using the midpoint of the anterior cortex of L5 as a reference point. Four distinct types could be identified:. Type-A – SIJ height is above the midpoint of the anterior cortex of the L5 vertebra. Type-B – SIJ height is between the midpoint and the lowest point of the anterior cortex of the L5 vertebra. Type-C – SIJ height is below the lowest point of the anterior cortex of the L5 vertebra. Type-D – a subgroup for those with a lumbosacral transitional vertebra, in particular a sacralised L5. Differences in transosseous corridor widths and lateral mass angles between classification types were assessed using two-way ANOVAs. Type-B was the most common pelvic type followed by Type-A, Type-C, and Type-D. Significant differences in the axial and coronal corridors was observed for all pelvic types at each level. Lateral mass angles increased from Types-A to C, but were smaller in Type-D. This classification system offers a guide to surgeons navigating variable pelvic anatomy and understanding how it is associated with the differences in transosseous sacral corridors. It can assist surgeons’ preoperative planning of screw position, choice of fixation or the need for technological assistance

Standard fixation for intra-articular distal humerus fracture is open reduction and internal fixation (ORIF). However, high energy fractures of the distal humerus are often accompanied with soft tissue injuries and or vascular injuries which limits the use of internal fixation. In our report, we describe a highly complex distal humerus fracture that showed promising healing via a ring external fixator. A 26-year-old man sustained a Gustillo Anderson Grade IIIB intra-articular distal humerus fracture of the non-dominant limb with bone loss at the lateral column. The injury was managed with aggressive wound debridement and cross elbow stabilization via a hinged ring external fixator. Post operative wound managed with foam dressing. Post-operatively, early controlled mobilization of elbow commenced. Fracture union achieved by 9 weeks and frame removed once fracture united. No surgical site infection or non-union observed throughout follow up. At 2 years follow up, flexion - extension of elbow is 20°- 100°, forearm supination 65°, forearm pronation 60° with no significant valgus or varus deformity. The extent of normal anatomic restoration in elbow fracture fixation determines the quality of elbow function with most common complication being elbow stiffness. Ring fixator is a non-invasive external device which provides firm stabilization of fracture while allowing for adequate soft tissue management. It provides continuous axial micro-movements in the frame which promotes callus formation while avoiding translation or angulation between the fragments. In appropriate frame design, they allow for early rehabilitation of joint where normal range of motion can be allowed in controlled manner immediately post-fixation. Functional outcome of elbow fracture from ring external fixation is comparable to ORIF due to better rehabilitation and lower complications. Ring external fixator in our patient achieved acceptable functional outcome and fracture alignment meanwhile the fracture was not complicated with common complications seen in ORIF. In conclusion, ring external fixator is as effective as ORIF in treating complex distal humeral fractures and should be considered for definitive fixation in such fractures

Abstract. Background. Fracture dislocation of the knee involves disruption of knee ligaments with associated tibial plateau fracture. If these injuries are not evaluated swiftly, can result in a limb-threatening injury. The aim of this study is to look at the clinical outcomes of a single surgeon case series at a major trauma centre. Methods. Prospectively collected data was analysed for a 5-year period. Primary outcome measures used were International Knee Documented Committee (IKDC) score and Knee Injury & Osteoarthritis Outcome Score (KOOS). The secondary outcome measures include Tegner activity scale, knee range of movements and complications. Results. 32 patients were presented with the mean age was 34 years (range 17–74). 14% of patients sustained vascular injury and 19% had common peroneal nerve injury. Priority was given for early total repair/reconstruction with fracture fixation within three weeks where feasible (90% of patients), and if not, a staged approach was adopted. The mean IKDC score was 67 (35–100) & KOOS was 74 (40–100). The mean preoperative Tegner Activity Scale was 6.5 whereas post-operative Tegner Activity Scale was 3.6 The mean flexion achieved postoperative was 115 (90–130). The two common patterns of injuries seen were Anterio-medial rim fractures (52%) with avulsion injuries of posterio-lateral corner structures and posteriomedial plateau fractures with ACL avulsion injuries. The first pattern was commonly associated with vascular and common peroneal nerve injury (90% of patients). Conclusion. To our knowledge, this is the first kind of study to report some fracture patterns that can be associated with particular ligamentous injuries

Multiligament knee injuries (MLKI) are rare and life-altering injuries that remain difficult to treat clinically due to a paucity of evidence guiding surgical management and timing. The purpose of this study was to compare injury specific functional outcomes following early versus delayed surgical reconstruction in MLKI patients to help inform timing decisions in clinical practice. A retrospective analysis of prospectively collected data from patients with MLKIs at a single academic level 1-trauma center was conducted. Patients were eligible for inclusion if they had an MLKI, underwent reconstructive surgery either prior to 6wks from injury or between 12weeks and 2 years from injury, and had at least 12months of post-surgical follow-up. Patients with a vascular injury, open injuries or associated fractures were excluded. Study participants were stratified into early (12 weeks - 2 years from injury). The primary outcome was patient reported, injury specific, quality of life in the form of the Multiligament Quality of Life questionnaire (MLQOL) and its four domains (Physical Impairment, Emotional Impairment, Activity Limitations and Societal Involvement). We secondarily analyzed differences in the need for manipulation under anesthesia, and reoperation rates, as well as radiographic Kellgren Lawrence (KL) arthritis grades, knee laxity grading and range of motion at the most recent follow-up. A total of 131 patients met our inclusion criteria, all having had surgery between 2006 and 2019. There were 75 patients in the early group and 56 in the delayed group. The mean time to surgery was 17.6 ± 8.0 days in the early group versus 279 ± 146.5 days in the delayed. Mean postoperative follow-up was 58 months. There were no significant differences between early and delayed groups with respect to age (34 vs. 32.8 years), sex (77% vs 63% male), BMI (28.3 vs 29.7 kg/m2), or injury mechanism (p>0.05). The early surgery group was found to include more patients with lateral sided injuries (n=49 [65%] vs. n=23 [41%]; p=0.012), a higher severity of Schenck Classification (p=0.024) as well as nerve injuries at initial presentation (n=35 [49%] vs n=8 [18%]; p0.05), when controlling for age, sex, Schenck classification, medial versus lateral injury, and nerve injury status. In terms of our secondary outcomes, we found that the early group underwent significantly more manipulations under anesthesia compare with the delayed group (n=24, [32%] vs n=8 [14%], p=0.024). We did not identify a significant difference in physical examination laxity grades, range of motion, KL grade or reoperation rates between groups (p>0.05). We found no difference in patient reported outcomes between those who underwent early versus delayed surgery following MLKI reconstruction. In our secondary outcomes, we found significantly more patients in the early surgery group required a manipulation under anesthesia following surgery, which may indicate a propensity for arthrofibrosis after early MLKI reconstruction

Patients with a vascular injury, open injuries or associated fractures were excluded. Study participants were stratified into early (<6wks from injury) and delayed surgical intervention (>12 weeks – 2 years from injury). The primary outcome was patient reported, injury specific, quality of life in the form of the Multiligament Quality of Life questionnaire (MLQOL) and its four domains (Physical Impairment, Emotional Impairment, Activity Limitations and Societal Involvement).

The early surgery group was found to include more patients with lateral sided injuries (n=49 [65%] vs. n=23 [41%]; p=0.012), a higher severity of Schenck Classification (p=0.024) as well as nerve injuries at initial presentation (n=35 [49%] vs n=8 [18%]; p<0.001). Multivariable linear regression analyses of the four domains of the MLQOL did not demonstrate an independent association with early versus delayed surgery status (p>0.05), when controlling for age, sex, Schenck classification, medial versus lateral injury, and nerve injury status. In terms of our secondary outcomes, we found that the early group underwent significantly more manipulations under anesthesia compare with the delayed group (n=24, [32%] vs n=8 [14%], p=0.024). We did not identify a significant difference in physical examination laxity grades, range of motion, KL grade or reoperation rates between groups (p>0.05). We found no difference in patient reported outcomes between those who underwent early versus delayed surgery following MLKI reconstruction. In our secondary outcomes, we found significantly more patients in the early surgery group required a manipulation under anesthesia following surgery, which may indicate a propensity for arthrofibrosis after early MLKI reconstruction

Objective:. To observe the incidence of intra-operative vascular injuries during anterior cervical decompression and fusion (ACDF). Secondly, management and monitoring of the outcome post vascular injury during ACDF. Methods:. This a prospective study. A review of all spinal patients' records was performed from June 2006 to April 2011. A comprehensive literature review was also utilized. Inclusion criteria – all patients had ACDF post trauma. All non-traumatic cases were excluded. Results:. The study consisted of 55 patients; 15 were females and 40 were males. The age distribution was 23–65 years. Two patients were excluded due to non-traumatic causes. Of the remaining 53 patients, four sustained intra-operative vascular injuries during ACDF surgery. All 4 patients had corpectomies, and one case was an iatrogenic injury. The commonly injured vessel during the ACDF surgery was the left vertebral artery. Haemostatic control was achieved via tamponade and haemostatic agents. The left common carotid was iatrogenically injured in one case and was treated by microvascular repair. Three patients were treated with antiplatelet therapy for three months duration. The patient with an iatrogenic injury was treated with anticoagulation therapy for three months duration. All computerized tomographic angiograms at three months follow up illustrated patent vessels. Conclusion:. There is an increased incidence of intra operative vascular injuries during ACDF associated with corpectomies. It is essential to be aware of the low incidence of intra operative arterial injury during ACDF and to have a management approach, such as tamponade or microvascular repair. Anticoagulation and antiplatelet therapy is effective in decreasing the complications of vascular injuries post ACDF

Abstract. Background. Fracture dislocation of the knee involves disruption of two or more knee ligaments with associated tibial plateau fracture. If these injuries are not evaluated swiftly, can result in a limb-threatening injury. The aim of this study is to look at the clinical outcomes of a single surgeon case series at a major trauma centre. Methods. Prospectively collected data was analysed for a 5-year period. Primary outcome measures used were International Knee Documented Committee(IKDC) score and Knee Injury & Osteoarthritis Outcome Score(KOOS). The secondary outcome measures include Tegner activity scale, knee range of movements & complications. Results. 23 patients were presented with the mean age was 37 years(17–74). 14% of patients sustained vascular injury & 19% had common peroneal nerve injury. Priority was given for early total repair/reconstruction with fracture fixation within 3 weeks where feasible (90% of patients), and if not, a staged approach was adopted. The mean IKDC score was 67 & KOOS was 73. The mean postoperative Tegner Activity Scale was 3.6 with mean flexion of 115(90–130). We observed some patterns of tibial plateau fractures are associated with similar patterns of ligamentous injuries. The anterio-medial rim fractures (52%) were associated with PCL, ACL & avulsion injuries of posterio-lateral corner structures. Most of the neurovascular injuries happened in this group. The other recognisable pattern was posterio-medial fractures, which were associated with ACL avulsion injury. Conclusion. To our knowledge, this is the first kind of study to report some fracture patterns that can be associated with particular ligamentous injuries

Introduction. The available scoring methods and outcome analysis methods in lower extremity skeletal trauma with vascular injuries are not always specific. Biochemical parameters like venous blood lactate, bicarbonate and serum CPK (at the time of admission and serial monitoring) were measured to assess whether they supplement clinical parameters in predicting limb salvageability in lower extremity skeletal trauma with vascular injuries. Materials and methods: 74 adult patients with long bone fracture of lower limb associated with vascular injury (open and closed) were included in the study group. Patients with significant head injury (who cannot provide informed consent) and those with mangled extremities (MESS score>8) were excluded. Methodology. Pre-operative requirement for fasciotomy was recorded. A vascular surgery consultation was obtained. CT angiography and DSA were performed if needed only. Venous blood samples from the injured limb were withdrawn for lactate and bicarbonate analysis. Serum CPK was estimated at the time of admission and repeated at 6, 12, 24, 48 and 72 hours after admission. A record was maintained about the type and duration of surgery, blood loss, type of anaesthesia used and fasciotomy in the post-operative period. Results. Of the 74 patients included in the study, 55 patients were taken up for a revascularization procedure, 13 patients for primary amputation and in remaining six patients, no vascular surgery was required. If the level of bicarbonate in the injured limb was less than 16.5 mmol/L, pH < 6.89 the probability of survival of the limb after a revascularization procedure is low and the injured limb will need an amputation eventually. Lactate levels and creatinine kinase were not of any predictive value regarding the outcome of the injured limb. Conclusion. Along with clinical signs, low levels of bicarbonate (<16.5 mmol/L), pH (<6.89), and high levels of pCO2, base deficit in the injured limb at the time of presentation were associated with the less favorable outcome-amputation

Purpose of study. Computerised Tomographic Angiography (CTA) is less invasive than conventional angiography. It is our perception that CTAs are being requested and performed too frequently at our institution without correct indications. We assessed the number of CTAs that were done, the percentage of vascular injuries sustained and whether correct indications were followed when requesting CTAs. Methodology. A review of records of the radiology department to determine the number of CTAs done for suspected extremity vascular injuries from January to December 2012. Inclusion criteria were CTAs performed during this period for suspected vascular injuries in fractures and dislocations and extremity gunshot wounds. A retrospective chart review was performed to determine the mechanism of injury, clinical picture (pulses, temperature, capillary refill and neurology), indications for and results of the CTA. Results. During this time 285 CTAs were performed of which 137 were suitable for analysis. One hundred and fifteen were males. The average age was 30.25 (range 14 to 86) years. Eighty six (62.77%) of the CTAs were normal. A further 4 patients showed no vascular injury, but with external compression of the vessels. The mechanism of injury was gunshot wounds in 58% of cases, motor vehicle accidents in 16.8% and pedestrian-motor vehicle accidents in 15%. 58.5% of cases with abnormal pulses had normal CTAs. Twenty one patients had normal pulses, but 5 of these had abnormal CTAs. Clinical assessment of peripheral pulse had a sensitivity of 81.5%, specificity of 34%, positive predictive value of 41.5% and negative predictive value of 76%. Conclusion. Thirty one (58.5%) of cases with abnormal pulses had normal CTAs, indicating that clinical examination is unreliable. Twenty one (15.3%) patients with normal pulses on clinical examination had CTAs performed. We believe CTAs are over-utilised due to availability rather than relying on serial clinical examination and non invasive testing. NO DISCLOSURES

Introduction: Vascular injuries associated with limb bone fractures are relatively uncommon. Aim: To determine the mechanisms of injury and evaluate the outcome of combined orthopaedic and vascular injuries. Method: A retrospective review of all patients with vascular injury associated with limb bone fractures between January 1992 and July 2006 was performed. Data collected included demographic details, clinical presentation, assessment, management and outcome. Results: Of 22,340 fractures treated during the 14 years period 36 patients sustained a vascular injury that required surgical intervention. Of those, 18 patients (50%) had a concomitant fractures or other orthopaedic injury this group form the basis of the audit. The median age was 31.1 (range 3–80) years, and 66% were male. Road traffic accidents accounted for 12 injuries (66%), other accidents 4(22%), iatrogenic injury 1(6%), and 1 gunshot injury (6%). Four patients had an associated nerve injury with varying severity. Skeletal fixation preceded vascular repair in most of the cases. Peroperative arterial shunting was not used in any patient. The primary vascular procedures included end-to-end anastamosis 2(11%), bypass grafting 1(6%), interposition vein grafts 8(43%), vein patch 1(6%), direct arterial repair 2(11%), ligation 2(11%), primary amputation 1(6%), reposition of normal course of artery 1(6%). During a 17 months follow-up period, the upper and lower limb preservation rate was 100 and 89%, respectively. Nine patients (50%) were symptom free; three patients (16.6%) had a neurological deficit. Conclusion: Vascular injury is uncommon in the orthopaedic patients. High suspicion and early intervention is essential to optimise outcome and function
