INTRODUCTION: Scaphoid is the most fractured carpal bone, with a 5-10% nonunion rate. Treatment challenges include choosing the implant and graft that best corrects humpback deformity and carpal malalignment with higher chances of bony healing.
OBJECTIVE: Compare cortico-cancellous and cancellous grafts between two groups of patients treating scaphoid nonunion with locking plates using autologous bone graft and evaluate bone healing rates and radiographic, tomographic, and functional parameters before and after surgery.
METHODS: Non-randomized prospective study including 20 cases of scaphoid nonunion. Groups were divided into Group A (ten patients treated with cortico-cancellous iliac graft) and Group B (ten patients treated with cancellous iliac graft). Patients underwent pre- and postoperative radiographs, computed tomography, and functional evaluation.
RESULTS: In postoperative analysis, Group A showed a statistically significant difference in intrascaphoid angle (p = 0.002) and scapholunate angle (p = 0.011) correction when comparing the pre- and postoperative periods. Group B showed a statistically significant difference in intrascaphoid angle (p = 0.002) and scapholunate angle correction (p = 0.0018), grip strength (p = 0.002), and tip pinch strength (p = 0.001) when comparing the pre- and postoperative periods. By comparing both groups, Group B showed a statistically significant difference in intrascaphoid angle correction (p = 0.002), grip strength (p = 0.002), tip pinch strength (p = 0.002), and radial deviation (p = 0.0003). There was no statistical difference when comparing bony healing between groups.
CONCLUSION: Scaphoid nonunion treatment with a locking plate was effective, showing a high bony healing rate and improved carpal alignment in imaging tests for both graft types. However, results for intrascaphoid angle correction, grip strength, tip pinch strength, and radial deviation were better in Group B.
LEVEL OF EVIDENCE: IV, case series.
