External Fixator Applıcatıons in Phalanx and Metacarpal Bone Fractures

Aim: Hand injuries can be a great source of stress and a cause of disconnection from life by negatively impacting the work that patients do in their daily lives. This study aimed to evaluate the presence of fracture union and deformity in patients operated on with a mini external fixator for metacarpal and phalanx fractures in our institution. Method: A total of 148 patients who underwent external fixation due to phalanx and metacarpal bone fractures were retrospectively evaluated. The patients' radiographic examinations were performed, and fracture union and deformity were evaluated. The results were clinically assessed by applying joint movements and scoring the Total Active Joint Range of Motion (Strickland-Glogovac finger function scale). Results: The patients were operated on within the first three days after their trauma; 17 (15.3%) of the patients had metacarpal fractures, 94 (84.7%) had phalanx fractures, 8 (47%) of the metacarpal fractures were 2nd metacarpal fractures, and 26 (27.6%) of the 94 patients with phalanx fractures had 5th finger fractures. According to the Strickland–Glogovac finger function scale, the number of patients with active joint range of motion >150 (excellent) was 45, the number of patients with 125–149 (good) was 36, the number of patients with 90–124 (moderate) was 20, and the number of patients with <90 (poor) was 10. In total, excellent and good results were found in 81 patients.Conclusion: Mini external fixators should be preferred more frequently among surgical options for tubular bone fractures of the hand because they are easy to apply, have satisfactory stability, are safe, allow for painless early mobilization, and provide versatility in treatment options.
