Background: Fractures of the hand are common injuries and in particular, fractures involving the articular surfaces can present difficulties to the orthopedic surgeon in practice. Objective: To assess how to surgically manage intra-articular fracture of the base of the first metacarpal bone by Dynamic K-wire External Fixator. Subjects and methods: This was a non-randomized clinical trial carried out at Al-Azhar University Hospitals on 10 patients, during the period from March 2018 till May 2020. Results: The mean time before operation was 9.5±5, Blunt trauma was most common type of trauma with a percent of 60%.The mean operative time (minutes) was 40.1 ±2 with range of (30-45) minutes and mean time for k wire removal was 28.1 ±5 with range of (15-41).There was significant improvement of Quick DASH functional scoring. There was high significant improvement of range of motion. There is significant difference between the normal and operated side as regard range of motion. Regarding complications, 10% of cases had post-operative pain which continued whole period of follow up, 0% had secondary arthrosis, 10% had superficial pin tract infection and 0% had valgus deformity. Conclusion: Closed reduction and external fixation can be effective and safe treatments for unstable fractures at the base of the first metacarpal. Such external fixation structures were simple and versatile and able to simultaneously achieve effects such as meeting the retractor, adjusting the angulation, and shortening the displacement, especially for local wounds. |
