At short-term follow-up, the arthroscopic Latarjet procedure with double-button fixation exhibited a low complication rate. Operative time significantly improved with surgical experience and was optimized after 30 cases. Early clinical results confirmed that this procedure can be safe and reliable.

Scapholunate dissociation or scaphoid pseudarthrosis may lead to osteoarthritis of the wrist. When osteoarthritis affects the midcarpal joint, proximal row carpectomy is no longer possible and only 4 corners fusion or capitolunate arthrodesis may be indicated. However, in some cases, osteoarthritis or bone necrosis may involve the lunatum, making partial arthrodeses impossible. Total arthrodesis may be proposed in such cases, but with a loss of range-of-motion. Total prosthesis may be considered but the results of this procedure are not always encouraging. Consequently, in these situations, we perform pyrocarbon prosthesis implant, replacing the head of the capitatum. This article describes the procedure and the results of a preliminary study.

Mucous cysts do not always require treatment. Nevertheless, patients often ask for excision because of pain or esthetics. Flap coverage is usually a concomitant procedure, which improves the quality of the skin overlying the distal interphalangeal joint. We propose the Zimany bilobed flap in this indication, and particularly its newer geometric design developed by Zitelli. We report the use of this flap in 9 cysts. Wound healing was fast with a good outcome. This flap design is an easy, safe procedure, and the Zitelli geometric design is a clear improvement for the reproducibility and learning curve.

The main complication of volar locking plates for distal radius fractures is flexor tendon rupture. The flexor pollicis longus (FPL) is the most commonly ruptured. Repair of the pronator quadratus (PQ) is one of the ways to prevent tendon rupture. The main purpose of this series was to evaluate the role of PQ repair after volar plating to prevent flexor tendon rupture using ultrasound (US). This work was a mono-operator prospective series of 20 consecutive patients with volar locking plates for distal radius fracture between September 2014 and May 2015. The PQ was repaired in all patients. A clinical, ultrasound, and perioperative evaluation of the flexor tendon was performed by this same surgeon. There was no flexor tendon rupture or tenosynovitis. There were no type A cases, which are characterized by contact between the plate and the FPL, and mostly type C cases, which are characterized by no contact between the plate and the FPL on US imaging. The suture of the PQ was sustainable over time when we removed the plate. Pronator quadratus repair is one of the ways to prevent flexor tendon rupture after volar plating. The outward-running suture is an effective technique for repairing the PQ. Ultrasound may be helpful during follow-up to detect asymptomatic flexor tendon irritation.
