Outcomes of cementless joint prosthesis versus tendon interposition for trapeziometacarpal osteoarthritis: a prospective study.

We compared 84 patients with the Ivory trapeziometacarpal prosthesis versus 62 with ligament reconstruction and tendon interposition arthroplasty performed for osteoarthritis. There were 134 women and 12 men with a mean age of 60 years. Prospective clinical assessment was made using the Quick Disability of the Arm, Shoulder and Hand (DASH) questionnaire, visual analogue scale for pain, range of motion, and grip and pinch strength. The mean follow-up was 4 years (range 2-5). Prosthetic replacement provided significantly better thumb abduction, adduction, pinch strength, QuickDASH, pain relief, satisfaction and a faster return to daily activities and previous work. Revision surgery was required for two patients in the prosthesis group, two for dislocation and one cup loosening, while in the ligament reconstruction group there were no revisions. We conclude that trapeziometacarpal prosthesis provides better mid-term results in terms of function compared with ligament reconstruction and tendon interposition for patients with Stages 2 and 3 osteoarthritis of the trapeziometacarpal joint. Level of evidence: II.

Indirect Scapholunate Ligament Repair: All Arthroscopic.

The arthroscopic technique most frequently used in acute scapholunate instability is reduction and fixation with Kirschner wires. To repair the injured ligament, open surgery and dorsal capsular plication are recommended, but this procedure has the risk of damaging secondary dorsal stabilizers, the dorsal blood supply, and the proprioceptive innervation of the posterior interosseous nerve. In this report, we present an all-arthroscopic technique of a dorsal reconstruction of the scapholunate interosseous ligament for scapholunate instability using a tape by tethering the scaphoid to the lunate.

Outcomes of Reverse Total Shoulder Arthroplasty for Proximal Humeral Fractures: Primary Arthroplasty Versus Secondary Arthroplasty After Failed Proximal Humeral Locking Plate Fixation.

OBJECTIVE: To compare the outcomes of reverse shoulder arthroplasty (RSA) between patients with failed proximal humeral locking plate (PHLP) fixation and those with acute fractures. DESIGN: Matched case-control study. SETTING: University hospital, Level I trauma center. PATIENTS: Thirty consecutive patients with fracture sequelae because of failed PHLP fixation (mean age 73) were age and sex matched to 30 patients with acute fracture (mean age 75). INTERVENTION: All patients underwent RSA. MAIN OUTCOME MEASUREMENTS: Constant, University of California Los Angeles (UCLA) and Disability of the Arm, Shoulder and Hand (DASH) scores. Radiological assessments were also performed. RESULTS: The mean postoperative follow-up was 3.2 (range, 2-5) years. All functional scores significantly improved from preoperative to postoperative (P = 0.001) in the sequelae group. Pain was relieved in all but one patient, and all but 2 patients were satisfied with their RSA. However, the functional outcomes at the last follow-up were significantly worse in the sequelae group compared with acute group in terms of adjusted Constant (P = 0.013), UCLA (P = 0.020) and DASH (P = 0.048) scores, strength (P = 0.01), anterior forward (P = 0.021), and abduction (P = 0.007). Six patients (20%) in the sequelae group had complications including 2 intraoperative (diaphyseal false passages), 2 early dislocations, 1 acromial fracture, and 1 aseptic loosening of glenoid component. Four of these patients were revised resulting all in a successful outcome at the last follow-up. In the acute group there was one intraoperative humeral fracture with no impact on the final outcome. CONCLUSIONS: Patients with failed PHLP fixation for fracture who were revised to RSA secondarily obtained marginally lower functional scores and higher complication rates compared with patients treated with primary RSA for fracture. However, patients who treated with secondary RSA had significant functional improvement and pain relief compared with their preoperative status, and most complications were manageable without a significant effect on final outcome. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Reverse shoulder arthroplasty versus hemiarthroplasty for acute proximal humeral fractures. A blinded, randomized, controlled, prospective study.

BACKGROUND: There is no consensus on what type of arthroplasty is best for the treatment of complex proximal humeral fractures in elderly patients. The purpose of this prospective study was to compare the outcomes of reverse shoulder arthroplasty (RSA) and hemiarthroplasty (HA). METHODS: Sixty-two patients older than 70 years were randomized to RSA (31 patients) and HA (31 patients). One HA patient died at 1 year, and she was excluded. The mean follow-up was 28.5 months (range, 24-49 months). RESULTS: Compared with HA patients, RSA patients had significantly higher (P = .001) mean University of California-Los Angeles (29.1 vs 21.1) and Constant (56.1 vs 40.0) scores, forward elevation (120.3° vs 79.8°), and abduction (112.9° vs 78.7°) but no difference in internal rotation (2.7° vs 2.6°; P = .91). The Disabilities of the Arm, Shoulder, and Hand score was higher in the HA patients (17 vs 29; P = .001). In the HA group, 56.6% of tuberosities healed and 30% resorbed. Patients with failure of tuberosities had significantly worse functional outcomes. There were 2 complications (intraoperative humeral fracture and superficial infection). One patient was manipulated under general anesthesia because of postoperative stiffness. Six patients with HA had proximal migration that required revision to RSA. In the RSA group, 64.5% of tuberosities healed and 13.2% resorbed. Functional outcome was irrespective of healing of the tuberosities. Notching was observed in only 1 RSA patient. One patient developed a hematoma and another a deep infection requiring a 2-stage revision to another RSA. CONCLUSION: RSA resulted in better pain and function and lower revision rate. Revision from HA to RSA does not appear to improve outcomes.
