Arthroscopic posterior capsulolabral repair grants adequate outcomes in shoulders with posterior instability without glenoid cartilage lesions.

Introduction: Posterior capsulolabral repair (posterior Bankart) is effective to restore shoulder stability and relieve pain, though a recent meta-analysis reported recurrent instability in 9.5% of patients, and that only 62.7% were able to resume sports.

Outcomes of Secondary Arthroscopic Distal Clavicle Resection for Shoulders With Symptomatic Acromioclavicular Joint Arthropathy After Isolated Rotator Cuff Repair With Complete Tendon Healing.

Background: Recent meta-analyses have advised against distal clavicle resection (DCR) as an adjuvant procedure during rotator cuff repair (RCR), whether performed routinely or in shoulders diagnosed with symptomatic acromioclavicular joint (ACJ) arthropathy. However, the efficacy of DCR as a secondary procedure in patients with persistent pain attributed to symptomatic ACJ arthropathy remains unknown.

Purpose: To evaluate outcomes of secondary DCR in patients with failed nonoperative treatment of symptomatic ACJ arthropathy after isolated RCR with complete tendon healing.

Repair of the dorsal capsuloligamentous scapholunate septum during arthroscopic resection of painful dorsal wrist ganglion cyst: Comparative analysis of two techniques.

We compared arthroscopic cyst resection (ACR) of dorsal ganglia of the wrist, either associated to reconstruction of the dorsal capsuloligamentous scapholunate septum (ACR-DCSS) in 66 cases in which the ganglia were painful on exertion, or isolated ACR in 15 pain-free cases. A single-center retrospective study analyzed data for the period April 2013 to May 2021. The main aim was to compare pre- and post-operative functional results (pain at rest (on a numerical rating scale: NRS), pain under effort (NRS), range of motion (°), grip strength (kg)) and recurrence rate between the two techniques.

Comparison of "Bilboquet" device and locking plate for surgical treatment of proximal humerus complex fractures at two years follow-up.

Purpose: Surgical treatment of three or four part fractures of the proximal humerus is complex. Different conservative techniques have been described. The main goal of this study was to compare the clinical and radiological outcomes of Bilboquet and locking plate at two year follow-up.

Expression cloning of KCRF, a potassium channel regulatory factor.

By functional coexpression screening of a rat cDNA library in Xenopus oocytes, we have cloned a protein (KCRF: K Channel Regulatory Factor) that reduces currents of several K(+) channels: G protein-activated GIRK1/4 (K(ir)3.1/K(ir)3.4), inward rectifier IRK1 (K(ir)2.
