The gold-standard for bone, ligament and joint surgery in the wrist is locoregional anesthesia in most countries. Wide-Awake Local Anesthesia No Tourniquet (WALANT) is commonly used for simple soft-tissue hand surgery procedures such as carpal tunnel or trigger finger release, and can now also be safely used in procedures such as proximal row carpectomy, scapholunate ligament repair or partial wrist fusion, to name but a few. This article describes the use of WALANT for complex surgery in the wrist. WALANT surgery offers many known benefits, such as enhanced patient safety and comfort, simplified perioperative process and avoidance of anesthesia-related risks, and also allows the surgeon to perform intraoperative testing of the repaired structures. Thus, the surgeon can tailor the rehabilitation program and shorten recovery time. We describe detailed guidelines for performing WALANT procedures safely and effectively, making it a favorable option for complex surgeries in the wrist.

The aim of this study was to analyze clinical and radiological results for 1-stage radiolunate arthrodesis and scaphoidectomy associated to the Sauvé-Kapandji procedure, to alleviate pain and conserve wrist motion.
Seven patients (8 wrists) with symptomatic osteoarthritis of the radiolunate and distal radioulnar joints were treated from 1999 to 2016. Mean age at surgery was 49 years and M/F sex ratio was 6/1. Etiologies were distal radial intra-articular malunion for 6 patients and bilateral gouty arthritis for 1. The procedure was performed by a dorsal approach in a single step. Pain was assessed on visual analogue scale (VAS). Pre- and post-operative active flexion-extension and pronation-supination were compared. The secondary endpoint was onset of postoperative complications.
At a mean 71 months\' follow-up (range, 30-168 months), there was significant reduction in pain (VAS, 0.5/10; p < 0.0001). Motion results were satisfactory, with 32° flexion, 39° extension, for a non-significant decrease of 11° and 5° respectively; pronation and supination were significantly increased, by a mean 23° and 30° respectively. Three wrists (37.5%) required a second surgery. There were no cases of surgical site infection or non-union.
Radiolunate arthrodesis and scaphoidectomy combined to Sauvé-Kapandji procedure was an effective solution for the treatment of symptomatic radiolunate and distal radioulnar osteoarthritis.

Osteoid osteoma is a benign bone tumor usually arising in the diaphysis and metaphysis of the long bones, with male predominance (sex ratio, 2:1). Despite being the most common bone tumor in the wrist, it is still an atypical location for this lesion. The usual presentation is pain that is exacerbated at night and relieved by aspirin or non-steroidal anti-inflammatory drugs. This presentation is not always the case in the wrist, which leads to numerous differential diagnoses and often a delay in definitive diagnosis and treatment. Various imaging modalities can confirm the presence of the tumor and guide the surgical approach. Resection is the gold-standard, with radiofrequency gaining popularity in recent years.

We report the case of an 80-year-old woman who presented with an asymptomatic slowly growing mass in the dorsal aspect of her right wrist. Radiographs revealed a snail-shaped radiopaque structure. Surgical exploration and excision revealed a calcified lesion over the extensor digitorum communis. Histopathological analysis confirmed the diagnosis of tenosynovial chondromatosis. At the last follow-up, four years after surgery, the patient was asymptomatic and free of recurrence. Practitioners and hand surgeons should be aware of the dorsal involvement and evocative radiological calcifications of tenosynovial chondromatosis, which is a rare benign soft tissue neoplasm that affects all tendon sheaths of the hand.

Intercarpal arthrodesis is a well-established option to treat various disorders of the carpus, such as localized osteoarthritis, carpal instability, and Kienböck\'s disease. This is a non-conservative procedure aimed at obtaining a stable and congruent interface between the radius and the proximal carpal row, which restores wrist function by minimizing pain and restoring grip strength. These procedures generally yield good predictable results that are maintained over time. However, all intracarpal arthrodesis procedures cause a loss of wrist range of motion. To optimize outcomes and minimize complications, especially nonunion, this surgery may require a learning curve. A precise surgical technique for preparing the bone surfaces, bringing enough bone graft, and using reliable fixation is essential. Since the late 1960s, several intracarpal arthrodesis procedures have been described. Commonly used fusions target the scaphotrapeziotrapezoid, scaphocapitate, four corners, capitolunate or capitohamatolunate regions. Lesser used fusions focus on specific lesions such as the scapholunate, scapholunocapitate, lunotriquetral and triquetrohamate. Here, we propose a systematic review of the various types of intercarpal arthrodesis procedures described in the literature. After having described each arthrodesis, we specify their indications, the variations of the surgical techniques, and then present an overview of the results and complications. Finally, we discuss how these surgeries affect wrist biomechanics. LEVEL OF EVIDENCE: III.

We investigated the effect of an extended denervation procedure in the thumb carpometacarpal (CMC) joint in patients suffering from CMC osteoarthritis. Between 2006 and 2018, 46 patients underwent the procedure in our clinic and were included in this retrospective study. Pain, strength, range of motion, DASH score, complications and overall satisfaction were determined. Assessment showed a significant decrease in pain and excellent physical function at a median 5 years\' follow-up. Twelve patients needed secondary surgery due to persistent pain. Overall, 28 of the 46 patients were satisfied with the results of the denervation. Even though the results of CMC denervation are poorer than with simple trapeziectomy, considerable pain relief can be achieved in selected young, physically active patients by exclusively soft-tissue surgery, conserving the biomechanical properties of the joint. In case of failure of the procedure, all other options remain available.

Carpal tunnel syndrome (CTS) can be bilateral, with varying incidence. Carpal tunnel release (CTR) in one wrist may relieve the symptoms of the contralateral wrist, avoiding the need for second surgery; conversely, the symptoms may persist or worsen, requiring contralateral surgery in some cases. The present study investigated whether surgical treatment was finally required for the non-operated CTS wrist, and in what cases non-operative treatment was possible. We compared baseline characteristics, risk factors and electrodiagnostic data between CTS patients who underwent only unilateral CTR and those who subsequently underwent bilateral surgery at various time intervals. This single-center retrospective study included 188 patients with bilateral CTS managed between 2010 and 2020; 137 patients (group 1, 73%) underwent only unilateral CTR, and 51 (group 2, 27%) subsequently underwent contralateral CTR. In group 1, contralateral CTS symptoms were assessed in 4 categories and compared to the presenting symptoms in the index wrist. There were no significant differences in age, gender, preoperative symptom duration, body status, addictive behavior, electrodiagnostic study or comorbidities, other than a higher rate of dialysis in group 2. The contralateral wrist showed partial or complete symptom relief in 57% of patients undergoing unilateral CTR. High BMI and history of diabetes were risk factors for persistent severe CTS or subsequent contralateral CTR.

Hamatolunate impingement syndrome is an uncommon cause of ulnar-sided wrist pain in the general population. Often misdiagnosed and untreated by non-specialized physicians, it is an important source of chronic ulnar wrist pain in golfers. The purpose of this retrospective study was to report results of arthroscopic burring of the apex of the hamate for hamatolunate impingement, whether isolated or not, in golf players, with a minimum of six months follow-up. Fifteen golf players (10 amateur, 2 semi-professional and 3 professional players), aged 40-61 years, with ulnar carpal pain implicating hamatolunate impingement with Viegas type-II carpal configuration, were included. Treatment consisted in arthroscopic burring of the apex of the hamate. At an average follow-up of 11 months (range, 6-24 months), all patients were satisfied with functional results, except 1 with persistent pain and stiffness; 93% returned to sport to their prior level. Mean range of motion was improved by 17 ° for wrist flexion (range, 15 ° to 30 °) and 15 ° for wrist extension (range, 10 ° to 25 °). All patients except 1 recovered grip strength, improving from 27 kg (range, 12-53) preoperatively to 35 kg (range, 17-61) at last-follow-up, and ulnar-sided pain was alleviated during golf practice. Return to prior sport level was possible by 5.5 months for professional players and by 9 months for amateurs. Arthroscopic burring of the apex of the hamate provided good clinical results for function and pain, with fairly rapid return to sport. Hamatolunate chondritis does not always mean pathology but represents the natural progression of Viegas type II wrists.

Semiconstrained arthroplasty of the distal radioulnar joint (DRUJ) (Scheker prosthesis, Aptis Medical, Glenview, KY, USA) is a treatment option in case of irreparable destruction of the DRUJ. In our unit, a Scheker endoprosthesis was implanted in 5 wrists in 4 patients. 3/5 wrists (60%) in 3/4 patients (75%) underwent revision surgery. Reasons for revision surgery were implant loosening, periprosthetic fracture of the radius and suspicion of periprosthetic infection. Asymptomatic loosening of the screw of the radial head cover was detected in one wrist. Scheker arthroplasty is technically demanding. The prosthesis is prone to failure over the long term. Before implantation, all patients should be informed of the high risk of revision surgery.
