Aims. Management of displaced paediatric supracondylar elbow fractures remains widely debated and actual practice is unclear. This national trainee collaboration aimed to evaluate surgical and postoperative management of these injuries across the UK. Methods. This study was led by the South West Orthopaedic Research Division (SWORD) and performed by the Supra Man Collaborative. Displaced paediatric supracondylar elbow fractures undergoing surgery between 1 January 2019 and 31 December 2019 were retrospectively identified and their anonymized data were collected via Research Electronic Data Capture (REDCap). Results. A total of 972 patients were identified across 41 hospitals. Mean age at injury was 6.3 years (1 to 15), 504 were male (52%), 583 involved the left side (60%), and 538 were Gartland type 3 fractures (55%). Median time from injury to theatre was 16 hours (interquartile range (IQR) 6.6 to 22), 300 patients (31%) underwent surgery on the day of injury, and 91 (9%) underwent surgery between 10:00 pm and 8:00 am. Overall, 910 patients (94%) had Kirschner (K)-wire) fixation and these were left percutaneous in 869 (95%), while 62 patients (6%) had manipulation under anaesthetic (MUA) and casting. Crossed K-wire configuration was used as fixation in 544 cases (59.5%). Overall, 208 of the fixation cases (61%) performed or supervised by a paediatric orthopaedic consultant underwent lateral-only fixation, whereas 153 (27%) of the fixation cases performed or supervised by a non-paediatric orthopaedic consultant used lateral-only fixation. In total, 129 percutaneous wires (16%) were removed in theatre. Of the 341 percutaneous wire fixations performed or supervised by a paediatric orthopaedic consultant, 11 (3%) underwent wire removal in theatre, whereas 118 (22%) of the 528 percutaneous wire fixation cases performed or supervised by a non-paediatric orthopaedic consultant underwent wire removal in theatre. Four MUA patients (6%) and seven K-wire fixation patients (0.8%) required revision surgery within 30 days for displacement. Conclusion. The treatment of supracondylar elbow fractures in children varies across the UK. Patient cases where a paediatric orthopaedic consultant was involved had an increased tendency for lateral only K-wire fixation and for wire removal in clinic. Low rates of displacement requiring revision surgery were identified in all fixation configurations. Cite this article: Bone Joint J 2023;105-B(1):82–87

Aims

This study evaluates the quality of patient-reported outcome measures (PROMs) reported in childhood fracture trials and recommends outcome measures to assess and report physical function, functional capacity, and quality of life using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) standards.

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

Aims

The current global pandemic due to COVID-19 is generating significant burden on the health service in the UK. On 23 March 2020, the UK government issued requirements for a national lockdown. The aim of this multicentre study is to gain a greater understanding of the impact lockdown has had on the rates, mechanisms and types of injuries together with their management across a regional trauma service.

Introduction. Both cross and lateral pinning are common techniques used for displaced supracondylar elbow fractures in children. Our study aims to determine whether there are any radiological differences in outcome between the two techniques. Most recent studies involving radiological evaluation of supracondylar fractures had concentrated on use of Bauman's angle or humerocapitellar angles. Rotational displacement, which has been shown to be critical for stability, is often not adequately addressed. Our evaluation measures both linear displacement using Bauman's angle and rotational displacement through the measurement of the lateral rotational percentage (LRP). Method. We retrospectively reviewed the radiographs of all type III supracondylar fractures reduced with either crossed pins (one medial and one lateral, one medial and two lateral) or lateral pins (two or three lateral) between 2002 and 2006 at the Royal Children's Hospital. A good quality AP and lateral radiograph taken preoperatively, immediately postoperatively, and at the first follow up session was required for patients to be included in the study. Those that had LRP change of greater than 10% were further investigated. Results. 66 of the 184 patients identified with type III supracondylar fracture with k wire fixation had adequate radiographs for the study. Thirty-three in the lateral pinning group and 33 in the cross pinning group. Results using Mann-Whitely test show nil significant differenced between the crossed and lateral pinned groups in terms of both Bauman's (p value 0.5767) angle and Lateral Rotational Profile (p value 0.063). Those that had LRP change were further investigated. The results showed that there was no difference between the cross pinning and lateral pinning in carrying angle or range of motion by the time of their last follow up. Conclusion. There is no significant difference in terms of the rate of loss of reduction radiologically using either the lateral pinning or crossed pinning method for treatment of type III supracondylar fractures in children

Delayed presentation of displaced supracondylar elbow fractures in children is a unique problem, but not uncommon in our hospital settings. The purpose of this study was to evaluate the results of our novel technique of closed manipulation and percutaneous pinning of these late presenting fractures. We used this technique in fourteen children, with an average age of seven years five months, who presented after an average delay of sixteen days. Through a limited incision technique, manipulation was done using a long curved artery forceps (under image intensifier). Final realignment was obtained and cross k wire fixation done. At follow-up (average twenty-two months) there were only four children who had cubitus varus greater than one hundred and needed corrective osteotomy. There were no neurovascular injuries. The other two patients with cubitus varus of sixty were satisfied with the appearance of their elbow. Final evaluation was done using Flynn criterion. The procedure however is quite demanding and needs expertise in closed pinning techniques. Though this technique holds promise in managing the difficult “SUPRACONDYLAR DILEMA”, yet larger series and multicentric trials are needed to establish the efficacy

Purpose of the study: Appropriate treatment of displaced supracondylar fractures of the distal humerus in children remains a controversial topic. Blount reduction followed by percutaneous or open pin fixation have been widely used. The purpose of this study was to analyze outcome after open surgical treatment of these fractures in pediatric trauma victims. Material and methods: The study included all pediatric patients who underwent surgical treatment for displaced supracondylar fractures of the distal humerus over a ten year period. Fractures were classified III or IV according to Lagrange and Rigault. Cross pinning was used in all cases, via a posterior approach or a double lateral and medial approach. The mechanism of the fracture and pre- and postoperative vascular and neurological complications were noted. The long-term assessment included standard x-rays of the elbow joint (ap and lateral views) and a physical examination to search for misalignment and residual neurological disorders. Results: We identified 110 patients, 61 boys and 49 girls, mean age 7.61 years (range 2–15 years). There were 96 grade IV fractures and 24 grade III. Mechanisms were: sports accident (n=44), fall from height (n=36), fall from own height (n=30). A neurological complication was observed in 29 children, skin opening in three and regressive vascular damage in six. A posterior approach was used for 95 patients and a double approach for 15. There was one revision for secondary displacement. Five patients developed transient paresthesia of the ulnar nerve which resolved without sequela. Three patients presented a moderately hypertrophic or deformed callus which had little functional impact. One patient with an open fracture required surgerical arthrolysis for stiffness six months after fracture. Discussion and conclusion: Open surgery is a very reliable treatment for supracondylar elbow fractures with a low rate of short- and long-term complications. Ulnar nerve palsy, the classical complication of percutaneous cross pinning, can be attributed to the medial pin (7–16% of cases in the literature). The Blount method and Judet or Métaizeau fixations can sometimes be complicated by secondary displacement or a deformed callus, complications which were almost never observed in our series. The results obtained in this series favor our approach for open surgery for the treatment of displaced supracondylar fractures of the distal humerus in children
