Objective: To describe the surgical treatment of a metacarpal deviation caused by an untreated Salter-Harris type I fracture in a heifer.
Study Design: Case report.
Animal: 9-month-old German Fleckvieh heifer.
Methods: A closing wedge osteotomy was performed to correct deviation of fused metacarpal III and IV. A triangular bone wedge was removed and the proximal and distal fragments of the bone were brought into apposition and stabilized with an 11-hole T-plate. A full-limb cast was applied postoperative.
Results: Radiographs were taken at 2, 4, and 6 weeks postoperative. No postoperative complications occurred and the heifer was discharged from the clinic 51 days after surgery. Radiographs taken 6 months after discharge showed periosteal callus formation around the closing wedge osteotomy. At 24 months postoperative, implants were intact and the heifer was in good general condition.
Conclusion: Closing wedge osteotomy was successfully performed in a heifer with a metacarpal deviation, correcting the malunion after a untreated Salter-Harris type I fracture. Radiographs showed evidence of osteotomy healing and the heifer had full use of the affected leg at 24 months postoperative.

Bernard and Irene Schwartz Center for Biomedical Imaging, Department of Radiology, New York University Grossman School of Medicine, New York, NY, USA.
Article Synopsis
- A new approach for real-time volumetric dynamic MRI of the wrist joint is introduced, aimed at improving the evaluation of wrist instability by tracking carpal bone motion during active movement.
- The study utilized a specialized wrist coil and 3D-printed support platform to capture high-quality 2D images, which were then assembled into dynamic 3D volumes for analysis.
- Results showed that the method provided high signal-to-noise ratio and accurate visualization of carpal bones, paving the way for advanced segmentation and quantitative assessment of wrist kinematics.

Article Synopsis
- * 64 patients aged 60-78 with unilateral closed distal radius fractures were divided into two groups: one using groove splints and the other using conventional splints, each group consisting of 32 patients.
- * Evaluations included measuring swelling, blood flow velocity, and functional outcomes over various time points post-treatment, using specific metrics and radiographic assessments to analyze the results.

Department of Pediatric Orthopaedics, Guangdong Provincial Clinical Research Center for Child Health, GuangZhou Women and Children's Medical Center, GuangZhou Medical University, 9th JinSui Road, GuangZhou, 510623, China.
Article Synopsis
- Wu et al. developed a modified radiographic classification system for congenital thumb duplications (CTD), showing reliable results among different evaluators, but previous studies had not focused specifically on type C3 CTD with bone attachment at the metacarpal level.
- The aim of the study was to assess the radiographic features of type C3 CTD, define its various anatomical subtypes, and suggest a new categorization to guide surgical approaches based on radiographic anatomy.
- The analysis involved 215 patients with type C3 CTD, leading to a new four-type classification system based on thumb joint alignment and hypertrophic epiphysis, successfully categorizing all affected thumbs and providing insights into frequency and demographics of the condition.
