Tóm tắt

Finger contractures, resulting from burns, trauma, or congenital anomalies, often lead to significant functional impairment. Z-plasty is a versatile reconstructive technique used to release scar contractures while preserving local tissue characteristics. This study aimed to evaluate the functional outcomes of different Z-plasty techniques in the surgical release of contracted fingers. We conducted a prospective descriptive case series involving 31 patients (38 fingers) undergoing Z-plasty for digital contractures. Depending on the location and severity of the contracture, three Z-plasty techniques were used: five-flap, double-opposing, and single 60° Z-plasty. Patients were followed for a mean of 5.6 months. Primary outcomes included range of motion (ROM), web space angle, and DASH scores. Complications and patient satisfaction (VAS) were also assessed. All techniques demonstrated significant improvements in finger extension and flexion. Mean extension deficit improved from −35.4° to −8.1°, and flexion increased from 62.3° to 81.7° (P < .001). The five-flap Z-plasty achieved the greatest gain in web space angle (from 24.2° to 46.8°). DASH scores decreased significantly from 47.6 to 21.8 (P < .001), with patient satisfaction increasing from 4.2 to 8.1 on VAS. Minor complications occurred in 5 patients (16.1%), with no cases of flap necrosis or wound infection. Z-plasty is an effective and low-risk technique for releasing digital contractures and restoring hand function. Five-flap and doubleopposing Z-plasty provide greater functional improvement in web space contractures, while single Z-plasty remains effective for linear joint contractures. These techniques offer reliable outcomes without the need for skin grafting, supporting their continued use in reconstructive hand surgery.
