RESUMO
BACKGROUND: The aim of this study was to describe for the first time the medium to long-term outcome after distal humeral hemiarthroplasty (DHH). METHODS: Twenty-six patients (mean age, 62; range, 29-92 years) treated with DHH for intra-articular distal humeral fractures and its sequelae were studied retrospectively. RESULTS: Four patients had died and 4 had been revised to total elbow arthroplasty: 2 for periprosthetic fractures and 2 for primary component loosening (all in prostheses without an anterior flange). Six other complications had occurred: ulnar neuritis, 4; stiffness, 1; and wound necrosis, 1. Seventeen patients underwent assessment at a mean of 80 months after surgery. The mean values of the American Shoulder and Elbow Surgeons (ASES) elbow score (pain, 9.93; function, 25; satisfaction, 9.06); Mayo Elbow Performance Score (90); Quick Disabilities of Arm, Shoulder and Hand (19), and EuroQol EQ5D (Index, 0.84; Visual Analog Scale, 80) outcome measures demonstrated good function and satisfaction with little pain. The mean flexion extension arc was 116°. There was no evidence of instability. Radiologic evidence of ulnar wear was seen in 13 patients and may be related to prosthetic design to some extent. Worse wear was associated with a higher ASES pain score, lower satisfaction score, and lower EuroQoL Visual Analog Scale of quality of life. Degree of wear correlates with time after surgery but not with age at the time of surgery. CONCLUSION: DHH offers a treatment option for unreconstructable distal humeral fractures and is associated with a good long-term outcome. LEVEL OF EVIDENCE: Level IV, case series, treatment study.

Controversy surrounds the optimal technique for fixation of displaced fractures, although locked intramedullary nailing is emerging as a preferred technique in managing displaced proximal humerus fractures in appropriately selected patients. This technique provides stable fracture fixation allowing early postoperative mobilization critical in ensuring a pain-free shoulder with a functional range of motion. Additional advantages include the ability to insert by way of a minimally invasive approach with limited soft tissue dissection, achieve accurate anatomic reduction, provide a secure construct even in the situation of osteopenic bone or comminution, and manage fractures of the proximal humerus extending into the shaft.

Fishtail deformity of the elbow is characterised by a contour abnormality of the distal humerus, which develops when the lateral trochlear ossification centres fails to develop or resorbs. It is an uncommon complication usually following a distal humeral fracture in childhood. Whilst initially presumed to be a benign condition, long-term follow-up suggests that patients with fishtail deformity are prone to functional impairment, ongoing pain and the development of early osteoarthrosis. This paper reviews the imaging findings in fishtail deformity, the proposed aetiology and the potential long-term complications.

Twenty-six patients who presented to our shoulder service with a symptomatic meso-os acromiale were reviewed. All had been initially treated for impingement symptoms. Nonoperative treatment had failed in all patients. One patient had also undergone an arthroscopic acromioplasty without benefit. The diagnosis of symptomatic os acromiale was made on the basis of radiographs and point tenderness over the acromion coupled with signs of rotator cuff pathology. We assessed these patients after treatment by internal fixation and bone grafting. Fixation was achieved with either K-wires or screws and tension banding with either wire or suture. Fifteen patients had associated rotator cuff tears. The clinical and radiologic results are reported. The rate of union was 96% (25/26), and 24 of 26 patients (92%) were satisfied with their results. The mean time to union was 4 months. There were two postoperative fractures. Eight patients (thirty-one percent) had postoperative pain that was subsequently relieved by wire or screw removal. Seventeen patients had concomitant rotator cuff tears. Eleven cuff tears were repaired, and six were irreparable. One of these six was extensively debrided. We conclude that open reduction-internal fixation of the symptomatic meso-acromion yields satisfactory results, and with the exception of hardware discomfort necessitating removal, minimal complications arise in the majority of cases.
