OBJECTIVE: To explore the technique and effectiveness of percutaneous retrograde cannulated screw fixation for acute stable scaphoid waist fracture by a transtrapezial approach.
METHODS: Between May 2010 and April 2012, 23 patients with acute stable scaphoid waist fracture were treated with percutaneous retrograde cannulated screw fixation by a transtrapezial approach. There were 18 males and 5 females, aged 21-54 years with an average of 32 years. All fractures were caused by supporting with hands after falling. The locations were the left side in 10 cases and the right side in 13 cases. The major symptoms included the wrist swelling, tenderness at the anatomic snuffbox, and grip weakness. Two cases were accompanied by distal radius fractures. The time between injury and operation ranged from 1 to 5 days with an average of 3 days.
RESULTS: All incisions healed by first intention. All the cases were followed up 4-26 months with an average of 10 months. All fractures healed 6-12 weeks postoperatively with an average of 8.2 weeks. The patients resumed normal life and work at 4-6 weeks and at 2-4 months after operation, respectively. At last follow-up, all the wrists were free from the pain and the tenderness. The postoperative grip power ranged from 30 to 51 kg (mean, 37 kg). The active flexion-extension range of motion was 140-165 degrees with an average of 153.7 degrees. All patients were satisfied with the results of treatment.
CONCLUSION: Percutaneous retrograde cannulated screw fixation by a transtrapezial approach is a simple, safe, and reliable method to treat acute stable scaphoid waist fracture. By this approach, it is easier to place the screws into the center of the long axis of scaphoid.
