Brief Summary

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.

Conditions

Union; Scaphoid; Non-Union Fracture; Herbert Screw; Volar Buttress Plate

Outcome Measures

Primary Outcomes (1)

• Mayo Wrist Score

  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.

  3 months post-procedure

Secondary Outcomes (1)

• Disabilities of the Arm, Shoulder and Hand (DASH) score

  3 months post-procedure
