Background Dynamic radiocarpal instability is one of the causes of post-trauma radial-sided wrist pain. It is not easy to diagnose and may possibly be overlooked. The key ligaments responsible for dynamic radiocarpal instability are the radioscaphocapitate (RSC) and long radiolunate (LRL) ligaments. Tensioning of these 2 ligaments could be a method of treatment for dynamic carpal instability. We proposed a method for arthroscopic thermal shrinkage of these 2 ligaments, and for setting a landmark arthroscopically to facilitate identification of these 2 ligaments during the combined open suture tensioning procedure. Methods Between January 2016 and May 2020, 12 patients treated with this method were enrolled. The mean age was 33.3 years (range, 18–57 years), and the mean duration from injury to operation was 7.8 months (range, 3–25 months). The diagnosis was mainly depended on the physical examinations and confirmed under arthroscopy. The mean follow-up was 17.7 months (range, 12–26 months). Results All the patients had marked improvement of pain, grip strength, the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), and the radiocarpal stability. The wrist range of motion showed significant decrease around 5o in both flexion and extension and around 4o in the ulnar deviation at the final follow-ups. All patients were able to return to their previous full level of work and activities. Conclusions We conclude that arthroscopic thermal shrinkage combined with open suture tensioning can be effective in treating dynamic carpal instability, while the arthroscopic-assisted landmark setting can help identify the accurate location of the RSC and LRL ligaments without dissecting too much soft tissue.
Background and Objectives: Many treatment modalities are available for juvenile hallux valgus. However, all of them have some disadvantages. Therefore, we developed a transosseous suturing procedure. Materials and Methods: Six patients (seven feet) with juvenile hallux valgus received transosseous suturing procedure. Clinical and radiological examinations were performed preoperatively and postoperatively. All patients underwent the soft tissue release procedure, followed by transosseous suturing with Fiberwire (in which sutures are anchored with mini plates). Results: The mean IMA and HVA decreased from 15.6° ± 2.6° to 7.3° ± 1.1° and 39.2° ± 3.3° to 12.5° ± 3.1°, respectively. Corrections achieved in the IMA and HVA of all patients were maintained through the last follow-up. The mean American Orthopedic Foot & Ankle Society score improved from 53.3 ± 3.5 to 86.9 ± 4.7 points. Conclusions: Based on these preliminary data, the transosseous suturing technique demonstrated satisfactory results and apparent improvements in the IMA and HVA without early complications.
For Bennett fractures with tiny avulsion fragments, healing may be jeopardized owing to limited fracture contact surface if displacement of reduced fracture junctions occurs. This study aimed to assess the efficacy of treating Bennett fractures with tiny avulsion fragments using percutaneous small-diameter K-wires for tiny fragment fixation and thumb carpometacarpal (CMC) joint transfixation. From 2011 to 2019, we retrospectively enrolled patients with Gedda type 3 Bennett fractures who underwent operation with K-wire percutaneous pinning for the tiny fragment and CMC joint. We enrolled a total of 13 patients (13 fractures) with a mean age of 26.9 years (range, 18–42 years) at operation and a mean follow-up time of 17.9 months (range, 12–34 months). At the final follow-up, the shortened Disabilities of the Arm, Shoulder and Hand Questionnaire mean score was 4.7, and the visual analog scale score for pain during activity was 0.7. Mean grip strength was 34.7 kg (97.7% of the value on the unaffected side). Mean pinch strength was 5.4 kg (90.5% of the value on the unaffected side). Mean first web opening angle was 66.2° (96.6% of the value on the unaffected side). There were no changes in gap and step-off during the healing process and no osteoarthritic changes in the thumb CMC joint at the final follow-up. For Bennett fractures with tiny avulsion fragment, percutaneous treatment with small-diameter K-wires for fragment fixation and thumb CMC joint transfixation provides a viable alternative with fracture healing and good functional outcomes.

Objective The dorsal approach is commonly used in open wrist arthrodesis. However, the extensor compartments and the dorsal wrist capsule need to be opened. We propose and evaluate a lateral approach using a small incision over the scaphoid anatomical snuffbox, which could be more straightforward for performing scaphoid excision and capitolunate arthrodesis in the treatment of scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC). Methods Between 2016 and 2021, 10 patients were enrolled retrospectively and underwent the lateral approach for scaphoid excision and capitolunate arthrodesis. We presented the radiographic outcomes, including fusion status, capitolunate angle, and carpal height ratio. The functional outcomes of wrist range of motion, grip strength, visual analog scale (VAS) score for pain, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, and Mayo wrist score were evaluated. The data obtained were analyzed and presented as the mean and standard deviation (SD). Results All 10 patients achieved solid bone fusion, and the mean follow‐up period was 20.4 (range 12–38; SD 10.1) months. Postoperatively, the mean capitolunate angle and carpal height ratio improved from 18.1° (range 8–34°; SD 8.6°) to 2.9° (range 0–5°; SD 1.9°) and 0.45 (range 0.40–0.49; SD 0.03)% to 0.50 (range 0.46–0.54; SD 0.02)%, respectively. The average preoperative and final follow‐up functional results were as follows: flexion‐extension arc of 76.5° (range 50–110°; SD 20.0°) and 74.0° (range 65–90°; SD 9.1°); VAS pain score of 5.8 (range 4–7; SD 1.0) and 0.9 (range 0–2; SD 0.6); QuickDASH score of 55.9 (range 40.9–79.5; SD 11.4) and 26.1 (range 18.2–36.4; SD 6.0); and Mayo wrist score of 46.5 (range 25–60; SD 13.8) and 72.5 (range 70–80; SD 3.5), respectively. Conclusions The lateral approach for scaphoid excision and capitolunate arthrodesis in treating SLAC and SNAC can provide a straightforward way for performance. This approach does not require disruption of the dorsal wrist capsule and extensor retinaculum. Bony healing can be achieved, and functional outcomes can be improved.
