Scapho-metacarpal dual mobility prosthesis for TMC-1 joint salvage: technical insights.

Introduction: Rhizarthrosis, or osteoarthritis of the trapeziometacarpal joint, predominantly affects women over 50, with up to 30% experiencing some degree of arthritis in this joint. Traditional surgical approaches, such as trapeziectomy with ligament reconstruction, can result in some patients in persistent pain or limited functionality. TMC ball-in-socket arthroplasty, with a cup placed in the distal scaphoid, offers a promising alternative to traditional arthrodesis or resection-suspension arthroplasty.

Radiographic evaluation of trapeziometacarpal total joint arthroplasty: Why and how?

Total joint arthroplasty is a promising surgical treatment for painful thumb trapeziometacarpal osteoarthritis. Strict surgical technique is essential to achieve a reliably good outcome. Preoperative radiographic evaluation before surgery and intraoperative fluoroscopy during surgery are valuable means of optimizing implant positioning.

Is the anconeus epitrochlearis muscle a predictor for ulnar nerve compression?

Background: The role of the anconeus epitrochlearis (AE) in cubital tunnel syndrome, either as protector or potential compressor of the ulnar nerve, as well as its prevalence in both symptomatic and asymptomatic patients are still unclear. This study aimed to assess the prevalence of the AE in a large cohort using 3-dimensional imaging and to investigate any association of the AE with preoperative or postoperative features of patients undergoing cubital tunnel surgery.

Methods: From a database of 1240 elbow MRIs, all patients with an AE were retrospectively screened for major criteria of cubital tunnel syndrome.

The pronator contracture syndrome: A new entity in supination restriction.

Forearm rotation is essential for daily activities and functional dexterity, involving both pronation and supination. Forearm rotation limitations can result from various pathologies, often linked to trauma, structural changes in radio-ulnar joints, and interosseous membrane alterations. Soft tissue contracture, such as post-burn scarring or specific neurological conditions, can also restrict forearm rotation.
