Treatment for Complex Elbow Fractures Involving Both a Hinged External Fixator and Internal Fixation

PurposeTo explore the clinical outcomes of a hinged external fixator combined with internal fixation in treating complex elbow fractures.MethodsThis was a retrospective analysis of 42 cases of complex elbow fractures treated in our hospital from January 2015 to December 2019. Twenty-four cases were treated with a hinged external fixator combined with internal fixation (external fixation group), including 14 cases of the terrible triad of the elbow, 5 cases of posterior Monteggia fracture, and 5 cases of transolecranon fracture-dislocation. Eighteen cases were treated with adjustable brace fixation combined with internal fixation (brace group), including 11 cases of the terrible triad of the elbow, 3 cases of posterior Monteggia fracture and 4 cases of transolecranon fracture-dislocation. All patients were treated with open reduction and internal fixation, and the patients with postoperative elbow instability underwent fixation with a hinged external fixator or adjustable brace. Preoperative and surgical data were collected. At the last follow-up, elbow motion (extension-flexion, rotation) was recorded in the two groups of patients, and the Mayo Elbow Function Score (MEPS) was used to assess elbow joint function.ResultsAll patients were followed up for 12 to 55 months (mean 28.2 months). The bones healed in all patients with fractures; the healing time was 12.9±1.9 weeks for the external fixation group and 12.2±1.8 weeks for the brace group, and the difference was not statistically significant (P＞0.05). The average flexion-extension range of the elbow joint in the external fixation group was 128.8°±15.7°, the average rotation range of the forearm was 142.7° ± 21.5°, and the average MEPS score was 89.8±11.3 points (range 60-100 points); 14 cases were excellent, 7 cases were good, 2 cases were fair, and 1 case was poor. The excellent and good rate was 87.5%. In the brace group, the average flexion-extension range of the elbow joint was 110.3°±37.0°, the average rotation range of the forearm was 125.6°±30.5°, and the average MEPS score was 81.1±15.5 points (50-100 points); 8 cases were excellent, 5 cases were good, 2 cases were fair, and 3 cases were poor. The excellent and good rate was 72.2%. The difference between the two groups was statistically significant (P <0.05).ConclusionsThe combination of an external fixator and internal fixation in the treatment of unstable complex elbow fractures can better restore the stability and function of elbow joints than can adjustable brace fixation.

Open reduction capsular arthroplasty using a modified Codivilla-Hey Groves-Colonna procedure augmented with tensor fascia lata graft, supported by Ilizarov hinged external fixator in a patient with chronic traumatic posterior hip dislocation

Untreated traumatic hip dislocation is a rare condition in children. Capsular arthroplasty is a previously abandoned surgical technique in dealing with developmental dysplasia of the hips but not described in traumatic dislocations. We present a 2-year follow-up of a 7-year-old boy who sustained chronic traumatic posterior hip dislocation treated as a first case in published literature combining a modified version of the Codivilla-Hey Groves-Colonna procedure, using tensor fascia lata graft and application of a hinged Ilizarov frame. The patient is currently independent on all activities of daily living.
