ABSTRACT
BACKGROUND: In acute treatment of radial head fractures, a radial head prosthesis can be considered if open reduction and internal fixation are not technically feasible. METHODS: We reviewed the data of 27 consecutive bipolar Judet radial head prostheses implanted in patients with unreconstructable radial head fractures and no other concomitant fractures (coronoid or olecranon factures). The lesions of the lateral collateral ligament were rated according to the McKee classification. Twenty-three patients with more than ten-year follow-up participated in this retrospective study All patients underwent assessments for pain, range of motion and stability using the Mayo Elbow Performance Score, the QuickDash questionnaire and a Visual Analogue Scale for pain. Radiography assessment was performed to determine the correct setting of the implant, presence of periprosthetic loosening, prosthetic disassembly, heterotopic ossification, capitellum and ulnohumeral degenerative changes. RESULTS: Mean follow-up was 149 months (± 12.2). Mean range of motion in flexion-extension was 111° (± 10.55), mean extension was 18° (± 14.32) and mean flexion was 130° (± 11.4). Mean arc of motion in supination-pronation was 150° (± 12.26). The mean Mayo Elbow Performance Score was 88, the mean QuickDash score was 7.3; 86% of the patients were satisfied. Seven patients (26%) required secondary surgery. The most frequent complication was heterotopic ossification, which had negative consequences on the functional result. CONCLUSIONS: Bipolar radial head prostheses are an option for acute treatment of isolated unreconstructable radial head fractures. During follow-up, three patients required implant revision and removal; the capitellum surface presented severe degenerative changes and the prosthesis was not replaced. Another complication was the risk of implant dislocation, in relation to implant design, incorrect positioning of the radial head stem or else to inadequate reconstruction of the lateral collateral ligament. Further work is needed to establish the long-term follow-up results of Judet implants in complex elbow fractures.

Background: Massive rotator cuff tears are defined as irreparable when tendon-to-bone or tendon-to-tendon continuity with the adducted arm cannot be restored and severe muscle fatty infiltration is present. Tendon transfer is a palliative procedure that improves shoulder function and relieves pain. Methods: We reviewed the records of patients aged <65 years, whose irreparable posterosuperior rotator cuff tears had been managed with teres major tendon transfer at our institution. Their 5- and 10-year clinical and radiographic follow-up records were examined to assess long-term outcomes. Patients' Constant Score, Disabilities of the Arm, Shoulder, and Hand score, and the visual analog scale for pain were calculated before the procedure and at 5 and 10 years. Results: There were 24 consecutive patients aged <65 years (mean, 59; 12 men and 12 women) who had received no prior treatment except rehabilitation. All patients underwent teres major tendon transfer due to the failure of conservative treatment. The mean Constant Score was 26 preoperatively and 68 and 66 at 5 and 10 years, respectively (P = .0001 and P = .25). The mean Disabilities of the Arm, Shoulder, and Hand scores were 62.2 preoperatively and 7.8 and 9.3 at 5 and 10 years, respectively (P = .0009 and P = .1). The mean visual analog scale scores at rest were 6.1 preoperatively, and 0.3 and 0.5 at 5 and 10 years, respectively (P = .0003 and P = .1). Based on Hamada's classification, at 5 years, 3 patients showed grade 2 changes, and another had grade 3 changes; at 10 years, 7 patients showed grade 2 changes, and one showed grade 3 changes. Complications (8%) developed after the 10-year evaluation and included pain in 1 patient and secondary rupture of the transfer in another. Discussion: Improving shoulder function and reducing pain in relatively young patients with irreparable posterosuperior cuff tears involves replacing the lost muscle with a muscle-tendon transfer. The chief aims of the procedure are to restore the balance with the subscapularis muscle, achieve joint stability, keep the humeral head in the glenoid cavity, and improve shoulder abduction and external rotation. Teres major tendon transfer can achieve these goals. Altogether, 22 of our 24 patients experienced improved daily activity function and pain relief that became stable after 5 years. Teres major transfers are useful surgical procedures, particularly in younger patients and in those with high functional demands, providing good and stable long-term results.
ABSTRACT
The lateral ulnar collateral ligament (LUCL) is a primary lateral stabilizer of the elbow that originates from the isometric center of the capitulum and inserts into the supinator crest of the ulna. LUCL injury may be due to trauma, chronic strain, or iatrogenic lesion. In patients with symptomatic LUCL insufficiency and recurrent posterolateral rotatory instability, surgical reconstruction can restore elbow stability. In primary acute treatment, the injured LUCL is reattached to the lateral epicondyle with transosseous sutures and anchors placed at the isometric origin of the ligament. If the ligament quality is poor, patients with chronic elbow instability may require reconstruction with a tendon autograft or allograft. Alternatively, the LUCL can be reconstructed by transposition of the local extensor fascia septum, a local flap that exploits the common extensor fascia connected to a thin strip of extensor digitorum quinti or the extensor digitorum communis intermuscular septum. We describe a new LUCL reconstruction technique based on the transposition of the local extensor fascia septum and report the preliminary result in a series of patients aged 50 years or less.
ABSTRACT
BACKGROUND: Open reduction and internal fixation is the gold standard for the operative treatment of intra-articular distal humeral fractures. However, in elderly patients the approach involves a high rate of complications. We reviewed the long-term outcomes of 13 primary total elbow arthroplasties (TEAs) performed to treat acute fractures in non-rheumatoid patients who at the time of trauma were aged less than 70 years. The aim of the study was to establish whether condyle retention enhances hinge stability and influences outcomes in these patients, who are younger than those who typically undergo TEA. METHODS: In 13 consecutive patients with acute distal humeral fractures aged 61-67 years, a linked semi-constrained Coonrad-Morrey prosthesis was implanted. The medial and lateral condylar bone fragments were resected (7 patients) or stabilized to the diaphysis using k-wires or plates (6 patients). RESULTS: At a mean follow-up of 12 years, the mean Mayo Elbow Performance Score was 88 and patient satisfaction was 85%. Nine patients (70%) did not require surgical revision. All revisions involved the group managed by condyle resection. DISCUSSION: TEA can be considered in elderly subjects with acute distal humeral fracture. In our patients, resection of the medial and lateral condyle fragments did not influence outcomes, although clinical observation suggested that it involves greater mechanical stress on the hinge, heightening the long-term risk of bushing wear. Condyle fixation with plates or k-wires seems to afford longer implant survival and is recommended in younger patients with higher functional demands.
