Treatment of old distal radius fractures through the approach by transection of brachioradialis tendon

Abstract

Objective To design the surgical approach by transection of brachioradialis tendon to expose the volar and dorsal side of the distal radius according to the anatomical characteristics of the distal radius adjacent structures, and explore the operative technique of this approach for the treatment of old distal radius fractures. Methods The characteristics and techniques of the surgical approach by transection of brachioradialis tendon were anatomically analyzed using 10 sides of the upper limb specimens of adult cadavers. 15 cases of old distal radius fractures were treated clinically by open reduction and internal fixation through the approach by cutting brachioradialis tendon. The patients' wrist function was evaluated using Fernandez score. Results The incision of brachioradialis tendon provided an adequate surgical exposure of the old distal radius fractures. The postoperative follow-up was 6 to 18 months with an average of 11.6 months. According to the Fernandez score, the results of wrist function at the last follow-up assessment were excellent in 11 cases, good in 3 cases and fair in 1 case. Conclusion Adopting the approach of cutting the brachioradialis tendon in the treatment of the old distal radius fractures has advantages of complete exposure of the surgical sites, clear operation vision and good postoperative recovery, which is worthy of clinical promotion.
