ABSTRACT
Background de Quervain's syndrome is one of the main tendonitis of the wrist. The hypothesis of authors was that de Quervain's syndrome could be successfully treated with a specific ultrasound-guided percutaneous procedure, as it is for trigger finger. Surgical Technique Identification of the subcompartmentalization of the first extensor compartment was performed first, using the Hiranuma's classification, prior to the surgery. Then, we assessed precisely the positions of the sensory branches of the radial nerve and drew the landmarks. Through a continuous ultrasound in-plane control, we performed a percutaneous retrograde section of each part of the first compartment of the extensors, using a dedicated surgical blade. Methods In a cadaveric study, authors proposed to assess the feasibility and safety of a new and specific procedure and then assessed their first clinical cases. Fourteen specimen wrists were analyzed with ultrasound and the procedure was performed prior to an open control of the efficiency of the release, and safety for the superficial nerves. Then, we reported the results of the 22 first patients included in the clinical series. Results In a cadaver laboratory, authors were able to identify with ultrasound the type of first compartment septation (subcompartmentalization) in 13 cases ( n = 14). The misidentification induced one incomplete release. No damages of the superficial radial nerve were observed despite close relationship. In the small series ( n = 22), the duration of surgery was 8 minutes (range: 4-18 minutes). It was performed in office surgery and no morbidities were noticed. All patients improved, from quickDASH preoperative score of 59 (range: 28-71) to quichDASH postoperative score of 9 (range: 0-25). Conclusion Ultrasound-guided percutaneous release in the de Quervain's disease is a safe and reliable procedure without specific morbidity. Great care should be taken to avoid sensory nerve injuries and to identify the correct type of subcompartmentalization with a precise ultrasound evaluation.

ABSTRACT
Symptomatic lunotriquetral coalition is very rare and need open surgery after failure of conservative treatment. We report a case of a symptomatic congenital lunotriquetral coalition type 1 according to the Minaar classification, at the left wrist of a 14-year-old boy. We performed an arthroscopic treatment with two compression screws and without cancellous bone grafting. Healing was obtained at 2 months postoperatively.
ABSTRACT
PURPOSE: This study presents an autograft technique for the surgical management of chronic posttraumatic instability of the thumb metacarpophalangeal (MCP) joint by using a bone-retinaculum-bone graft from the second compartment of the extensor retinaculum. METHODS: The bone-retinaculum-bone graft was harvested from the second compartment. The graft ends were fixed into the host site with screws. Fourteen patients (12 ulnar, 2 radial collateral ligament tears) had the procedure. All patients were reviewed by an independent observer using objective and subjective criteria, the mean follow-up time was 20 months. RESULTS: Results were satisfactory overall (8 excellent, 4 good, 1 fair, 1 poor that subsequently was fused). All patients returned to their former jobs. All but one had a clinically stable first MCP joint; grasp was 87%, pinch was 80%, MCP joint range of motion (ROM) was 91%, and interphalangeal joint ROM was 98% of the unoperated side. CONCLUSIONS: Early results are encouraging. This procedure preserves ROM of the MCP and interphalangeal joints of the thumb, improves strength, and gives the stability required for proper thumb function.
