Abstract
Usually, radius styloid process fractures without displacement are treated with immobilization. However, surgeons have to attend the wrist contracture after immobilization. We report the case of 2 patients (Case 1: a 45-year-old male and Case 2: a 37-year-old male) with radius styloid process fracture without displacement who were operated with break-away screws. Both patients recovered to excellent in the modified Mayo wrist score and no soft tissue complications were recognized.
Highlights
Radius styloid process fractures without displacement are treated with immobilization
After surgeon recognized no displacement in fluoroscopy, break-away screw (Acutwist®, Nihon Medical Osaka, Japan) can be inserted as same direction as guide wire
Radiographs showed a radius styloid process fracture (Chauffeur’s fracture, AO classification: type B1) with no displacement (Figure 1A and B). Since he was eager to return to his work quickly, osteosynthesis was chosen for this patient, and preservation of wrist and hand contractures due to splint fixation
Summary
The procedure was performed under locoregional anesthesia and tourniquet inflated to 250mm Hg after exsanguination of the extremity. One cm longitudinal incision was made on the radius styloid process. Dissection of soft tissue was performed with taking care of extensor pollicis brevis, abductor pollicis longus and superficial branch of radial nerve. Guide wire was inserted from tip of the radius styloid process. After surgeon recognized no displacement in fluoroscopy, break-away screw (Acutwist®, Nihon Medical Osaka, Japan) can be inserted as same direction as guide wire. The operative incision was covered with sterile bandage and fixation called for no immobilization after operation
