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. Medial humeral epicondyle fractures (MHEFs) are common elbow fractures in children. Open reduction should be performed in patients with MHEF who have entrapped intra-articular fragments as well as displacement. However, following open reduction, transposition of the ulnar nerve is disputed. The aim of this study is to evaluate the need for ulnar nerve exploration and transposition. Methods. This was a retrospective cohort study. The clinical data of patients who underwent surgical treatment of MHEF in our hospital from January 2015 to January 2022 were collected. The patients were allocated to either transposition or non-transposition groups. Data for sex, age, cause of fracture, duration of follow-up, Papavasiliou and Crawford classification, injury-to-surgery time, preoperative ulnar nerve symptoms, intraoperative exploration of ulnar nerve injury, surgical incision length, intraoperative blood loss, postoperative ulnar nerve symptoms, complications, persistent ulnar neuropathy, and elbow joint function were analyzed. Binary logistic regression analysis was used for statistical analysis. Results. A total of 124 patients were followed up, 50 in the ulnar nerve transposition group and 74 in the non-transposition group. There were significant differences in ulnar nerve injury (p = 0.009), incision length (p < 0.001), and blood loss (p = 0.003) between the two groups. Binary logistic regression analysis revealed that preoperative ulnar nerve symptoms (p = 0.012) were risk factors for postoperative ulnar nerve symptoms. In addition, ulnar nerve transposition did not affect the occurrence of postoperative ulnar nerve symptoms (p = 0.468). Conclusion. Ulnar nerve transposition did not improve clinical outcomes. It is recommended that the ulnar nerve should not be transposed when treating MHEF operatively. Cite this article: Bone Joint J 2024;106-B(2):212–218

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).

We reviewed the clinical and radiological results of six patients who had sustained traumatic separation of the distal epiphysis of the humerus at birth.

The correct diagnosis was made from plain radiographs and often supplemented with ultrasonography, MRI and arthrography. An orthopaedic surgeon saw two patients within two days of birth, and the other four were seen at between nine and 30 days. The two neonates underwent unsuccessful attempts at closed reduction. In the remaining patients, seen after the age of eight days, no attempt at reduction was made. All six displaced fractures were immobilised in a cast with the elbow at 90° of flexion and the forearm pronated.

When seen at a mean of 58 months (16 to 120) after injury, the clinical and radiological results were excellent in five patients, with complete realignment of the injury. In one patient the forearm lay in slightly reduced valgus with the elbow in full extension.

Traumatic separation of the distal epiphysis of the humerus may be missed on the maternity wards and not diagnosed until after discharge from hospital. However, even when no attempt is made to reduce the displaced epiphysis, a good clinical result can be expected.
