简要总结
This study aimed to evaluate the short-term results of treating non-united scaphoid waist fractures with a humpback deformity by graft and internal fixation using a volar buttress plate versus the use of a Herbert screw.
详细描述
Scaphoid fracture is the most common fracture, accounting for roughly 60% of the total carpal bone fractures and 11 % of all hand fractures.
Nonunion occurs in approximately 5% to 25 % of scaphoid fractures. The scaphoid nonunion will collapse into a humpback deformity, and the lunate, together with the proximal pole, into a dorsal intercalated segment instability, which might end in an advanced carpal collapse.
A scaphoid screw acts to prevent bending at the fracture site with three-point fixation within the cancellous bone of the scaphoid. The proximal and distal points of purchase are achieved by the capture of the screw threads in the cancellous bone of the proximal and distal poles of the scaphoid. The third point occurs within the cancellous bone of the scaphoid waist.

结局指标
主要结局
Mayo Wrist Score
时间窗: 3 months post-procedure
The Mayo Wrist Score is a fast and simple tool comprising four questions that assess pain intensity, wrist function, range of motion, and grip strength. Mayo Wrist Score ranges from 0 to 100. Scores of 90-100 are considered excellent, 80-90 good, 60-80 satisfactory, and below 60 poor.
次要结局
- Disabilities of the Arm, Shoulder and Hand (DASH) score(3 months post-procedure)
