Wrist arthroscopy has been used as an important adjunct procedure to distal radius fracture management. This procedure allows minimal surgical intervention and provides excellent visualization of the joint for anatomical restoration of articular fracture of the distal radius and early management of associated injuries. To many, it is still technically challenging to adequately perform arthroscopy in the distal radius fractures. With this review, we aimed to provide an updated arthroscopic technique in the management of distal radius fractures and potential pitfalls of this technique.

PURPOSE: Early stage Kienbock's disease is commonly treated with a surgical intervention to avoid progression to degenerative change. The purpose of this study was to evaluate the clinical and radiographic outcomes of conservative management in patients with an early stage Kienbock's disease with a hypothesis that the lunate can be maintained in patients with no pain or tolerable pain. METHODS: Twenty-three patients with a Lichtman stage I, II or IIIA Kienbock's disease were managed conservatively and investigated prospectively. There were ten men and thirteen women. Mean age at first visit was 53.9 years old and mean follow-up period was 51.3 months. The clinical outcomes were evaluated by range of motion, subjective satisfaction of patients at final follow-up. Radiographic measurements of the Lichtman stage were assessed at first visit and at the final follow-up. Three patients were Lichtman stage I, eleven patients were II and nine patients were IIIA. RESULTS: Range of motion improved in all cases. According to Dornan's criteria, eleven patients were excellent, another eleven patients were good and one patient was fair. Based on Lichtman stage, no change was seen in sixteen patients, while seven showed progression. Three patients revealed improved radiographic findings of the lunate at final follow-up. CONCLUSION: We found that conservative management including close observation of clinical and radiographic changes can provide satisfactory clinical improvement in patients with no pain or tolerable pain in early stage Kienbock's disease.

The treatment of a brachymetacarpia using conventional distraction osteogenesis requires holding an external fixator following distraction for stability, which causes prolonged discomfort that adversely affects the patient's daily activities. This paper reports a case of a 20-year-old male of brachymetacarpia treated with distraction osteogenesis combined with a plate reducing the period of an external fixator, allowing rapid return to the daily activities, and presenting good clinical results.

PURPOSE: The aim of this study was to determine the effectiveness of arthroscopic debridement with mini-open ulnar nerve decompression in primary osteoarthritis of the elbow with ulnar neuropathy. MATERIALS AND METHODS: Between May of 2006 and July of 2014, a total of 43 patients who had undergone surgery for primary osteoarthritis of the elbow with ulnar neuropathy were included in this study. We divided the subjects into two groups according to the method of surgery: group 1 (n=18) received mini-open ulnar nerve decompression only, and group 2 (n=25) received arthroscopic debridement with mini-open ulnar nerve decompression. Patients were assessed for the following clinical outcomes: visual analogue scales (VAS) score, range of motion of the elbow joint, Mayo elbow performance score (MEPS), and disabilities of the arm, shoulder and hand (DASH) at the time before surgery and 6 months after surgery. We analyzed the recovery of the ulnar nerve by the McGowan grade and Bishop rating score preoperatively and at 6 months after the surgery. RESULTS: The VAS score, range of motion of the elbow joint, MEPS, and DASH showed significant statistical difference after the surgery (p <0.05). However, between the 2 groups, there was no significant difference. For the McGowan grade, all cases of both groups–except one case each group–showed at least one grade improvement. Moreover, group 2 showed a greater significant difference than group 1 (p=0.001). At the final follow-up, according to the Bishop rating score, group 2 had a greater significant difference than group 1 (p=0.036). CONCLUSION: Arthroscopic debridement with mini-open ulnar nerve decompression in primary osteoarthritis of the elbow with ulnar neuropathy is a useful technique, which has several advantages, including the benefits associated with a minimally invasive surgery and also the improvement of elbow joint function and excellent recovery of the ulnar nerve.

BACKGROUND: The purpose of the current study is to investigate anatomical relationships between the muscle overlying the distal transverse carpal ligament (TCL) and the thenar motor branch of the median nerve. METHODS: Of the 192 wrists that underwent open carpal tunnel release, a muscle belly overlying the TCL was observed on the distal margin of TCL in 25 wrists and ligament exposure could not be achieved without transection of it. We recorded surgical findings of these 25 wrists. The origin of the recurrent motor branch arising from the major median nerve was marked on the axial and coronal section diagrams of the wrist. RESULTS: The presence of muscle overlying the TCL was seen in 25 wrists (21 patients, 13%). The locations of origin were distributed not only on the radial side but anterior or ulnar side of the major median nerve. Abnormal branches originated from the unusual side in 14 cases (56% of those with a muscle overlying the TCL): central-anterior side in eight cases, ulnar-anterior side in five cases, and ulnar side in one case. These anomalous branches were frequently associated with the muscle belly overlying the TCL in our study regardless of the origin site. The branches were prone to cut if careless midline incision along the third web space was performed. Unusual origin and aberrant pathway of the recurrent thenar motor branch were associated with the presence of a muscle overlying the TCL. CONCLUSIONS: A thorough knowledge of the standard and variant anatomy of the muscle belly and recurrent motor branch in the carpal tunnel is fundamental to prevention of complications such as muscle wasting or atrophy by iatrogenic motor branch injury during carpal tunnel release.
