Volar buttress plate fixation: An effective and reliable option for Bennett's fractures.

ABSTRACT

OBJECTIVES: This study aimed to demonstrate the volar plate fixation technique for fixing Bennett's fractures due to its buttress effect. PATIENTS AND METHODS: The retrospective study included 10 patients (8 males, 2 females; mean age 35.9±11.56 years; range, 17 to 51 years) who were treated using the volar plate fixation technique between January 2018 and August 2022. The postoperative functional scores of the patients were evaluated using the Q-DASH (Quick Disabilities of the Arm, Shoulder, and Hand) score, and their pain status was evaluated with the Visual Analog Scale (VAS). We also assessed fracture union and development of complications. We assessed opposition according to Kapandji grade and abduction of the thumb. RESULTS: The mean follow-up time was 16.6±2.91 (range, 12 to 21) months. The technique was performed on the right extremity in eight patients and on the left extremity in two patients. All patients were right-hand dominant. The VAS score was 1 in two cases and 0 in the other cases. The mean Q-DASH score was 1.36±2.44. The mean pinch strength was 6.4±0.89 kg, and the mean grasp strength was 18.8±3.52 kg on the injured side. The mean Kapandji grade of opposition was 9.3±0.82, while the mean abduction degree was 37.4±2.01. CONCLUSION: Based on the early results of this technique, we conclude that volar plate fixation for Bennett's fractures is reliable and allows for early motion, providing anatomical and stable joint reduction, and it does not have implant complications such as hardware irritation. However, fixation of small fragments may be particularly challenging.
