Scaphoid Fractures Requiring Bone Graft: Does Graft Source Matter?

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Bone Grafting Techniques

Background:

• Scaphoid fractures frequently necessitate bone grafting for healing.
• Traditionally, iliac crest bone grafts were standard, but distal radius grafts offer lower morbidity.
• The study investigates the comparative efficacy of these two graft sources.

Purpose of the Study:

• To compare treatment outcomes for scaphoid waist fractures using distal radius versus iliac crest bone grafts.
• To evaluate union rates, complication frequencies, and functional recovery between graft types.
• To inform surgical decision-making regarding graft site selection for scaphoid repair.

Main Methods:

• Retrospective review of 39 patients undergoing scaphoid waist fracture repair with bone grafting (2010-2020).
• Grafts sourced from either the distal radius (n=29) or iliac crest (n=10).
• Primary outcome: union rate assessed via imaging; secondary outcomes: complications, time to union, and alignment.

Main Results:

• No statistically significant difference in union rates between distal radius (97%) and iliac crest (80%) grafts (P = .16).
• Comparable complication rates, secondary surgery rates, time to union, and immobilization duration.
• Similar postoperative scapholunate angles were observed in both groups.

Conclusions:

• Distal radius and iliac crest bone grafts yield comparable union rates for scaphoid waist fractures.
• Given the lower morbidity of distal radius grafts, they are a recommended alternative to iliac crest grafts.
• This finding supports a shift towards utilizing distal radius bone grafts in scaphoid fracture management.
