Background. Proximal humeral fractures are common and a minority develop non-union, which can result in pain and disability. We aimed to identify the risk factors and quantify the prevalence of non-union. Methods. A thirteen-year retrospective study of 7039 patients with proximal humeral fractures was performed and a database created. 246 patients with non-union were compared to a control group to identify risk factors. Logistic regression analyses were performed to identify significant variables obtained at presentation to predict non-union. Results. The crude rate of non-union after any proximal humeral fracture is 3.5%, rising to 5.6% after excluding patients with isolated tuberosity fractures or those who underwent primary fixation. 179 patients with non-union were compared to a control group of 295 patients whose fractures healed. There was no significant difference between the groups and the entire study population in terms of age, gender and mechanism of injury. Univariate and multivariate logistic regression analyses identified 3 significant predictors for non-union: displacement of fracture (p<0.001); having a two-part fracture (p = 0.045); and varus angulation of the humeral head at injury (p<0.001). Conclusions. The prevalence of non-union of proximal humeral fractures (3.2/100,000population/year) is higher than previously appreciated and a modified classification (ongoing) is needed to include the identified risk factors

Background. Non-union has traditionally been considered a rare complication following the non-operative management of clavicle fractures. A growing body of evidence has demonstrated higher rates of non-union in adults with displaced fractures. However, the variables that predict non-union in these patients remain unclear. We evaluated the prevalence and risk factors for non-union following displaced midshaft clavicle fractures in a large consecutive series of patients managed non-operatively in our Unit. Materials and Methods. 1097 consecutive adults (mean age 26.1yrs) with displaced midshaft clavicle fractures treated non-operatively in our Unit were included. All patients were interviewed and examined by an orthopaedic trauma surgeon and underwent radiological assessment within a week of injury. All patients were managed in a simple sling for two weeks followed by early mobilization. All patients were followed-up until clinical and radiological confirmation of union. Non-union was defined clinically as the presence of pain or mobility of the fracture segments on stressing, and radiologically as failure of cortical bridging by 6 months. Results. 198 (18%) of patients had evidence of non-union at 6 months. Patient factors significantly associated with non-union included increasing age, smoking and the presence of medical comorbidities (p<0.05). Injury-related factors associated with non-union included Increasing fragment translation and displacement, and a severe pattern of injury (Edinburgh 2B2: comminuted segmental fracture)(p<0.01). Conclusions. We present the largest series reporting the prevalence and risk factors for non-union following conservatively treated, displaced midshaft clavicle fractures. These fractures can no longer be viewed as a single clinical entity, but as a spectrum of injuries each requiring individualized assessment and treatment. Increased understanding of the outcomes of these injuries will enable clinicians to better identify those patients that may be better served with primary operative reconstruction

Non-union has traditionally been considered a rare complication following the non-operative management of clavicle fractures. Recent studies demonstrate higher rates of non-union in adults with displaced fractures, yet the variables predicting non-union remain unclear. We evaluated the prevalence and risk factors for non-union following displaced midshaft clavicle fractures in a large consecutive series of patients managed non-operatively. 1097 consecutive adults (mean age 26.1yrs) with displaced midshaft clavicle fractures treated non-operatively in our Unit were included.

Infected non-union after severe open fracture or unsuitable fracture operation is frequently associated with bone defect and its treatment has been controversial. We have used microsurgical vascularised composite graft for these problematic cases. Fifty one patients aged 17∼70 year old (43.6 years old in average), including 41 men and 10 women. Follow-up has been more than 6 months. The vascularised composite graft included a free fibular osteocutaneous flap in 41 cases, a vascular pedicled fibular osteocutaneous flap in 2 cases, a free iliac osteocutaneous flap in 5 cases, a vascularised cutaneous flap in 2 cases and other in one case. All infected non-unions were united without trouble and co-existing infection was successfully eradicated. This method also enables the patients rapid bone union and subsequent early functional recovery. This success was attributed to greater transport of oxygen and good antibiotic perfusion in presence of good blood supply. We conclude that microsurgical vascularised composite graft for infected non-union is an extremely useful method with early bone union and subsidence of infection

Background. Controversy persists regarding preference between Herbert and Acutrak screw for internal fixation of scaphoid non-union. Acutrak screw has been shown to have better biomechanical compression properties than Herbert screw in the laboratory setting. The aim of this study was to assess the clinical, radiological and functional outcome of patients treated with the two different screw systems. Methods. A retrospective review of the results of patients with scaphoid non-union treated by a single surgeon. Group 1 comprised of 61 patients treated with Herbert screw between July1996 and June2000 and Group 2 comprised of 71 patients treated with Acutrak screw between July 2000 and December 2005. Union rates were assessed radiologically and clinically. Functional outcome was measured by using modified Mayo wrist score. Results. Both groups of patients were comparable in terms of age (25.3:27.3yrs, Herbert: Acutrak) and their occupations in relation to wrist loading. The mean time interval between injury and surgery was 12.2months for Herbert group (range: 3–144months) and 17months (range: 4–180months) in Acutrak group. Time to union was similar for both groups. Union rate was 93% (66) in Acutrak compared to 77% (47) in Herbert screw. Union rate was related to fracture site (Herbert p=0.01; Acutrak p=0.0001) and higher when the screw had been placed axially (Herbert; p=0.006, Acutrak; p=0.004) in the scaphoid. Ninety seven percent of screws had been placed axially in Acutrak compared to 84% in the Herbert. Functional outcome was satisfactory in 85% of Acutrak group compared to 67% in Herbert. Wrist fusion was performed in 4 patients in Herbert group due to progressive wrist pain and in 1 patient in Acutrak group due to similar reason. Conclusion. Acutrak screw provides more accurate method of screw placement and a higher union rate when compared to Herbert screw

Introduction

Scaphoid nonunions remain controversial with regard to optimal management. The objective of this article is to compare our clinical experience in the treatment of patients with scaphoid nonunion using distal radius non vascularised bone graft with that of iliac crest bone graft.

Midfoot arthrodesis is the conventional surgical intervention for midfoot arthritis. Arthrodesis aims to stabilise, realign and fuse the affected joints, providing patients with improved pain and function. Current research neglects the measurement of patient reported outcomes. This study aimed to investigate objective, and patient reported outcomes of midfoot arthrodesis. The secondary aim was to identify variables predicting the development of non-union. An automated search of online patient records identified 108 eligible patients (117 feet). The rates of union, re-operations, and complications were calculated using radiographs and medical records. Logistic regression was used to model variables influencing the odds of non-union. All living patients were posted a Manchester Oxford Foot Questionnaire (MOx-FQ), a patient reported outcome assessment. Pre-operative MOx-FQ results were available in a minority of cases. Students t-test was used to compare pre- and post-operative MOx-FQ scores. The rate of union achieved was 74%. The rate of re-operations was 35%. The rate of complications was 14%. Bone grafts and staple fixation independently impacted the odds of non-union. Bone grafts decreased the odds of non-union, whilst staple fixation increased the odds. This finding agrees with the opinion of other researchers. We recommend the use of bone grafts, and the avoidance of fixation with staples. Previous attempts have been made to assess patient outcomes. However, this study is the first to use the MOx-FQ, a validated questionnaire. Therefore, this study establishes a baseline for improvements in patient reported outcomes

The surgical care of extra-articular distal tibial fractures remains controversial. This study looks at the radiological outcomes of distal tibial fractures treated with either a direct medial or anterolateral plate, with or without plating of the fibula, to assess the outcome and complications associated with these 2 approaches. This is a retrospective review of 80 patients with distal tibial extra-articular fractures, treated with an open reduction and plating, between 2008 and 2019 at Glasgow Royal Infirmary. Case notes and x-rays were reviewed. Of those tibial fractures fixed with only a medial plate, 78% united (28/36), 5% (2/36) had a non-union and 17% (6/36) a malunion. In the group treated with a combination of medial tibial and fibular plating, the figures were; 71% (15/21), 19% (4/21) and 10% (2/21). However, in the group treated with anterolateral plating of the tibia alone, only 53% (8/15) united, with a 20% (3/15) non-union and 13% (2/15) malunion rate. Additionally in this group, there were 2 patients (13%) with loss of fracture reduction within the first two months of fracture fixation, requiring revision surgery. Interestingly, of the 8 patients treated with anterolateral tibial and fibular plating, 88% (7/8) showed full union and only one (12%) had a non-union, with no malunions is this group. It would appear that medial tibial and a combination of medial tibial and fibular plating, have superior outcomes compared to anterolateral plating. Results suggest, if anterolateral plating is done, this should be augmented by fixation of the fibular fracture as well

This prospective randomised trial aimed to assess the superiority of internal fixation of well-reduced medial malleolar fractures (displacement □2mm) compared with non-fixation, following fibular stabilisation in patients undergoing surgical management of a closed unstable ankle fracture. A total of 154 adult patients with a bi- or trimalleolar fracture were recruited from a single centre. Open injuries and vertically unstable medial malleolar fractures were excluded. Following fibular stabilisation, patients were randomised intra-operatively on a 1:1 basis to fixation or non-fixation after satisfactory fluoroscopic fracture reduction was confirmed. The primary outcome was the Olerud Molander Ankle Score (OMAS) at 12 months post-randomisation. Complications were documented over the follow-up period. The baseline group demographics and injury characteristics were comparable. There were 144 patients reviewed at the primary outcome point (94%). The median OMAS was 80 (IQR, 60-90) in the fixation group vs. 72.5 (IQR, 55-90) in the non-fixation group (p=0.165). Complication rates were comparable, although significantly more patients (n=13, 20%) in the non-fixation group developed a radiographic non-union (p<0.001). The majority (n=8/13) were asymptomatic, with one patient requiring surgical reintervention. In the non-fixation group, a superior outcome was associated with an anatomical medial malleolar fracture reduction. Internal fixation is not superior to non-fixation of well-reduced medial malleolar fractures when managing unstable ankle fractures. However, one in five patients following non-fixation developed a radiographic non-union and whilst the re-intervention rate to manage this was low, the longer-term consequences of this are unknown. The results of this trial may support selective non-fixation of anatomically reduced fractures

Stable Weber B fractures are typically treated non-operatively without complications but require close monitoring due to concerns over potential medial deltoid ligament injuries and the risk of delayed talar shift. Following recent evidence suggesting this is unlikely, a functional protocol with early weight bearing was introduced at Glasgow Royal Infirmary (GRI) following a pilot audit. This study aims to evaluate the risk of delayed talar shift in isolated Weber B fractures managed with functional bracing and early weight-bearing, particularly if signs of medial ligament injury are present. We conducted a retrospective review of 148 patients with isolated Weber B fractures without talar shift at presentation that were reviewed at the virtual fracture clinic at our institution between July 2019 and June 2020. The primary outcome was the incidence of delayed talar shift. Secondary outcomes were other complications and adherence to protocol. 48 patients had medial signs present and of these 1 (2%) showed possible talar shift on X-rays at 4 weeks, and was kept under review. This patient had a normal medial clear space at 3 months. No patients with medial signs not documented (n=19) or not present (n=81) had delayed talar shift. 10% of patients (n=15) had at least 1 complication: delayed union (n=2); non-union (n=3); ongoing pain (n=14). Functional bracing with early weight-bearing is a safe, effective protocol for managing isolated Weber B fractures without initial talar shift. This study concludes that the risk of delayed talar shift is low in all patients, with or without medial signs

The aim of the study was to report the survival of open reduction and internal fixation (ORIF) of Vancouver B fractures associated with the Exeter Stem (ES) at a minimum of 5 years. This retrospective cohort study assessed 129 consecutive patients with Vancouver B type fractures treated with ORIF from 2008-2016 at a minimum of 5 years. Patient records were examined, and the following recorded: details of primary prosthesis, details of injury, Vancouver classification, details of operative management, complications, and requirement for reoperation. Data was analysed using SPSS. Survival analysis was undertaken using the endpoint ‘reoperation for any reason’. Mean age at fracture was 78.2 (SD10.6, 46-96) and 54 (43%) were female. Vancouver subclassifications were: 24% B1, 70.5% B2 and 5.5% B3. For all Vancouver B fractures, Kaplan Meier analysis demonstrated a 5 year survival free from reoperation of 88.8% (82.0-94.7 95%CI). Fourteen patients required reoperation, most commonly within the first year for non-union and plate fracture (5.4%). Five-year survival for any reoperation differed significantly according to fracture type (p=0.016) and was worst in B1s: B1 76.6% (61.3-91.9); B2 92.6% 986.9-98.3); and 100% of B3. Univariate analysis identified B1 type (p=0.008) and a transverse fracture pattern (p=0.003) to be significantly associated with the need for reoperation. Adopting a strategy of fixation of all Vancouver B fractures involving the ES where the fracture was anatomically reducible and the bone cement interface was well-fixed was associated with a 5 year survival, free from reoperation of 88.8%

Aim of this study was to identify reoperation rates in patients with short oblique and transverse fractures around a well fixed cemented polished taper slip stem and to determine any associations with treatment failure. Retrospective cohort study of 31 patients with AO transverse or short oblique Vancouver B1 PFFs around THA (total hip arthroplasty) cemented taper slip stems: 12 male (39%); mean age 74±11.9 (range 44–91); mean BMI 28.5±1.4 (range 16–48); and median ASA 3. Patient journeys were assessed, re-interventions reviewed. The primary outcome measure was reoperation. Time from primary THA to fracture was 11.3±7.8yrs (0.5–26yrs). Primary surgical management was fixation in 27/31 and rTHA (revision total hip arthroplasty) in 4/31. 10 of 31 (32%) patients required reoperation, 9 within 2 years of fracture: 1 following rTHA and 8 following ORIF. The commonest mode of failure was non-union (n=6). No significant associations with reoperation requirement were identified. Kaplan-Meier free from reoperation was 67.4% (49.8–85.0 95% CI) at 2 years and this was unaffected by initial management with ORIF or rTHA (Log rank 0.898). Of those reoperated, 6/10 required multiple reoperations to obtain either bony union or a stable revision construct and 13% ultimately required proximal femoral endoprostheses. The relative risk of 1 year mortality was 1.6 (0.25 to 10.1 95%CI) among patients who required reoperation compared to those who did not. These are difficult fractures to manage, should not be underestimated and patients should be counselled that there is a 30% risk of reoperation and 20% of requiring multiple reoperations

The role of mesenchymal stem cells (MSCs) in enhancing healing process has been examined with allogeneic and xenogeneic cells in transplantation models. However, certain factors might limit the use of allogeneic cells in clinical practice, (e.g. disease transmission, ethical issues and patient acceptance). Adipose tissue represents an abundant source for autologous cells. The aim of this study was to evaluate adipose-derived autologous cells for preventing non-union. Adults male Wistar rats (n=5) underwent a previously published surgical procedure known to result in non-union if no treatment is given. This consisted of a mid-shaft tibial osteotomy with peri/endosteal stripping stabilised by intramedullary nail fixation with a 1mm gap maintained by a spacer. During the same operation, ipsilateral inguinal subcutaneous fat was harvested and processed for cell isolation. After three weeks in culture, the cell number reached 5×106 and were injected into the fracture site. At the end of the experiment, all tibias (injected with autologous fat-MSCs) developed union. These were compared with a control group injected with PBS (n=4) and with allogenic (n=5) and xenogeneic (n=6) cell transplantation groups. The amount of callus was noticeably large in the autologous cell group and the distal-callus index was significantly greater than that of the other groups, P-value =<0.05, unpaired t-test, corrected by Benjamini & Hochberg. We report a novel method for autologous MSCs implantation to stimulate fracture healing. Local injection of autologous fat-MSCs into the fracture site resulted in a solid union in all the tibias with statistically significantly greater amounts of callus

Arthrodesis of the 1st metatarsophalangeal joint (MTPJ) is a common procedure used for the treatment of end stage arthritis. We studied a cohort of patients who underwent an isolated 1st MTPJ Fusion for the treatment of hallux rigidus. Here we report the 10-year clinical outcomes, complication rate, requirement for further surgery and patient experience. All patients, who underwent an isolated 1st MTPJ Fusion for osteoarthritis from June 2008 until November 2011 were included. Demographics, clinical outcome data and subsequent procedures performed were collected from a departmental database (Bluespier). Patients were contacted and asked to complete the MOxFQ questionnaire and rate their satisfaction using pain, function and if they would undergo the surgery again. Mean follow up was 10.85 (range 9–12) years. A total of 161 patients (183 feet) underwent an isolated 1st MTPJ fusion during this time period. 156 of the feet showed a successful arthrodesis (85.2% fusion rate); 27 patients required revision surgery, 19 (10.4%) for a symptomatic non-union and 8 (4.4%) for mal-union. Those patients with co-morbidities (diabetes and gout) required revision earlier than those without (p<0.01). Average MOxFQ score was 16.6 (0–64) and 28 out of the 38 (73.6%) said they would have the operation again. Overall, the long-term results of the 1st MTPJ fusion had good outcomes with a successful fusion rate and minimal complications, both in line with the corresponding literature. In this series, fusion provided high patient satisfaction with the majority of patients opting to undergo fusion with the gift of hindsight

This study describes the introduction of a virtual pathway for the management of suspected scaphoid fractures and reports patient-reported outcome measures (PROMs) and satisfaction following treatment with this service. All adult patients that presented with a clinically suspected scaphoid fracture that was not visible on presentation radiographs over a one-year period were eligible for inclusion in the pathway. Demographics, examination findings, clinical scaphoid score (CSS) and standard four view radiographs were collected at presentation. All radiographs were reviewed virtually by a single consultant hand surgeon, with patient-initiated follow-up on request. PROMs were assessed at a minimum of one year post presentation and included the QuickDASH, EQ-5D-5L, the Net Promoter Score (NPS) and return to work. There were 221 patients referred to the virtual pathway. The mean age was 41 (range 16–87; SD 18.4 years) and there were 99 men (45%). There were 189 (86%) patients discharged with advice and 19 (9%) patients were recalled for clinical review (seven undisplaced scaphoid fractures, six other acute fractures of the hand or wrist, two scapholunate ligament injuries, and four cases where no abnormality was detected). Thirteen patients (6%) initiated follow-up with the hand service; no fracture or ligament injury was identified within this group. PROMs were available for 179 (81%) patients at a mean of 19 months follow-up (range: 13 – 33 months). The median QuickDASH score was 2.3 (IQR, 0–15.9), the median EQ-5D-5L was 0.85 (IQR, 0.73–1.00), the NPS was 76, and 173 (97%) patients were satisfied with their treatment. There were no documented cases of symptomatic non-union one year following injury. This study reports the introduction of a virtual pathway for suspected scaphoid fractures, demonstrating high levels of patient satisfaction, excellent PROMs, and no detrimental effects in the vast majority of cases

Background. Humerus fracture non-union is a challenge for which a wide range of treatments exist. We present our experience of managing these by hybrid Ilizarov frame fixation, without bone graft or debridement of the non-union site. Methods. Case notes review of a consecutive series of 20 patients treated for aseptic humeral non-union between 2004 and 2016. Eighteen patients had previous plate or intramedullary nail fixations, and 2 had no prior surgery. During Ilizarov application, any existing metalwork preventing dynamisation of the fracture site was removed through minimal incisions before compression of the fracture site was then achieved. Only 3 patients had open debridement or osteotomy of the non-union site, otherwise all other patients had no debridement of their non-union. Results. Bony union was achieved in 17 patients (85%), with a further 2 achieving a functional fibrous union. The remaining patient subsequently had successful open surgery. Union rates were 66% (2/3) and 88% (15/17) for the debridement/osteotomy and non-debridement groups respectively. Mean frame duration was 193 days. One patient was treated for pin-site infection. The Chertsey Outcome Score for Trauma was used to assess patient reported outcomes. Conclusions. Simple changes to the physical properties acting upon a humeral non-union, such as adequate control of its strain environment and restoration of the mechanical axis, are enough on their own to initiate healing. In our practice, this eliminates any morbidity associated with extensive fracture debridements or donor harvest sites

Aims. It has been generally accepted that open fractures require early skeletal stabilization and soft-tissue reconstruction. Traditionally, a standard gauze dressing was applied to open wounds. There has been a recent shift in this paradigm towards negative pressure wound therapy (NPWT). The aim of this study was to compare the clinical outcomes in patients with open tibial fractures receiving standard dressing versus NPWT. Methods. This multicentre randomized controlled trial was approved by the ethical review board of a public sector tertiary care institute. Wounds were graded using Gustilo-Anderson (GA) classification, and patients with GA-II to III-C were included in the study. To be eligible, the patient had to present within 72 hours of the injury. The primary outcome of the study was patient-reported Disability Rating Index (DRI) at 12 months. Secondary outcomes included quality of life assessment using 12-Item Short-Form Health Survey questionnaire (SF-12), wound infection rates at six weeks and nonunion rates at 12 months. Logistic regression analysis and independent-samples t-test were applied for secondary outcomes. Analyses of primary and secondary outcomes were performed using SPSS v. 22.0.1 and p-values of < 0.05 were considered significant. Results. A total of 486 patients were randomized between January 2016 and December 2018. Overall 206 (49.04%) patients underwent NPWT, while 214 (50.95%) patients were allocated to the standard dressing group. There was no statistically significant difference in DRI at 12 months between NPWT and standard dressing groups (mean difference 0.5; 95% confidence interval (CI) -0.08 to 1.1; p = 0.581). Regarding SF-12 scores at 12 months follow-up, there was no significant difference at any point from injury until 12 months (mean difference 1.4; 95% CI 0.7 to 1.9; p = 0.781). The 30-day deep infection rate was slightly higher in the standard gauze dressing group. The non-union odds were also comparable (odds ratio (OR) 0.90, 95% CI 0.56 to 1.45; p = 0.685). Conclusion. Our study concludes that NPWT therapy does not confer benefit over standard dressing technique for open fractures. The DRI, SF-12 scores, wound infection, and nonunion rates were analogous in both study groups. We suggest surgeons continue to use cheaper and more readily available standard dressings.

Aim. The aim of this study was to determine whether the absence of periosteal reaction on plain radiographs was predictive of exchange nail failure in lower limb diaphyseal fracture non-unions. Methods. A consecutive cohort of 20 femora and 35 tibiae undergoing exchange nailing for diaphyseal aseptic (n=39) and septic (n=16) fracture non-union at a single centre from 2003 to 2010. Multiple causes of non-union were found in 29 patients (53%) with infection present in 16 cases (29.1%). Of this cohort 49 fracture non-unions had complete radiographic records (19 femora and 30 tibiae) allowing evaluation of the periosteal callus. The primary outcome was the number of number of revision procedures required to achieve union. Failure was defined was as the requirement of >two revision procedures to achieve union. Results. The absence of periosteal callus from the fracture site on all four cortices conferred a relative risk ratio (RRR) 5.00 (p=0.006) of exchange nail failure in septic fracture non-unions. Receiver operator characteristic curve analysis of number of cortices with periosteal reaction for predicting exchange nail (>two exchange nail procedures) failure in both septic and aseptic cases found an area under the curve of 0.79 (95% confidence interval 0.675–0.904, p<0.0001). The complete absence of callus within 5 mm of the fracture site had a 75% chance of requiring 3 or more exchange nails to obtain union. Conversely the presence periosteal callus on at least one cortex within 5mm of the fracture site had a 100% chance the fracture would unite following 1 or 2 exchange nail procedures. Conclusion. Careful radiographic analysis of lower limb diaphyseal non-union should be undertaken before exchange nailing. The absence of periosteal reaction on plain radiographs in septic fracture non-union is predictive of exchange nail failure

Fractures of the lateral clavicle with complete displacement have a high non-union rate and are associated with poor functional outcomes following non-operative treatment. Various operative techniques are available but preliminary studies of open reduction and tunnelled suspensory device (ORTSD) fixation report good early functional outcomes with a low rate of complications. This study assesses the functional outcomes in a large series of patients treated using ORTSD. After surgical reconstruction in 67 patients, outcomes were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and Oxford score at six weeks, and three, six and twelve months post-operatively. 55 of 64 surviving patients were contacted at a mean of 69 (27–120) months to complete DASH and Oxford scores, evaluate overall satisfaction, and document any complications. At one year post-operatively, the mean Oxford score was 46.4 and mean DASH score was 2.4 points (59/67 patients assessed). At a mean of 69 months after surgery, the mean Oxford score was 46.5 and mean DASH score was 2.2 (55 surviving and contactable patients). There were no significant differences between the one-year functional scores and those at the latest follow-up. Two patients developed symptomatic non-union requiring re-operation, and two developed an asymptomatic fibrous union not requiring surgery. The five-year survival when considering only obligate revision for implant-related complications was 97.0%. ORTSD fixation for isolated displaced lateral-end clavicle fractures in medically-fit patients is associated with good functional outcomes, and a low rate of medium-term complications. Routine removal of the implant was not necessary

The aim of this study was to define the long-term outcome following adolescent clavicle fracture. We retrospectively reviewed all adolescent fractures presenting to our region (13–17years) over a 10-year period. Patient reported outcomes were undertaken at a minimum of 4 years post-injury (QuickDASH and EQ-5D) in completely displaced midshaft fractures (Edinburgh 2B, >2cm displacement, n=50) and angulated midshaft fractures (Edinburgh 2A2, >30 degrees angulation, n=32). 677 clavicle fractures were analysed. The median age was 14.8 (IQR 14.0–15.7) and 89% were male. The majority were midshaft (n=606, 89.5%) with either angulation (39.8%) or simple fully displaced (39.1%). Only 3% of midshaft fractures underwent acute fixation (n=18/606), all of which were fully displaced. The incidence of refracture following non-operative management of midshaft fractures was 3.2% (n=19/588), all united with non-operative management. Fracture type, severity of angulation or displacement was not associated with risk of refracture. There was one case of non-union encountered following non-operative management of all displaced midshaft fractures (0.4%, n=1/245). At a mean of 7.6 years following injury, non-operative management of both displaced and angulated fractures had a median QuickDASH was 0.0 (IQR 0.0–2.3), EQ-5D was 1.0 (IQR 1.0–1.0). 97% of angulated fractures and 94% of displaced fractures were satisfied with their final shoulder function. We conclude that Non-operative management of adolescent midshaft clavicle fractures result in excellent functional outcomes with a low rate of complications at long-term follow up. The relative indications for surgical intervention for clavicle fractures in adults do not appear to be applicable to adolescents
