Abstract
Introduction: Bone grafting is the main treatment of scaphoid nonunion. In this study, we intend to evaluate the radiographic results in patients with non-vascularized bone graft in scaphoid nonunion with or without AVN.
Materials & Methods: In a cross-sectional study, patients with scaphoid nonunion were chosen in a census sampling method and were followed up and immobilized with plasterfor four weeks. Then a radiography was taken and the patients were followed till the union were seen in radiography. Data were analyzed by SPSS 24.
Results & Discussion: In this study, 43 patients were admitted. The mean total age of patients was 29.91 ± 8.58 years.13 patients had complications, 6 reported limited mobility and 7 reported pain. Fifteen patients (34.9) had avascular necrosis. All patients were able to perform daily activities with hands, and none complained of inactivity. The mean duration of first incision to the end was 49.16 ± 5.98 minutes. The mean time elapsed from scaphoid fracture to surgery was 36.59 ± 47.42 weeks. The mean time from surgery to complete recovery was 145.79 ± 73.85 weeks. The mean time from surgery to the first evidence of healing was 36.59 ±47.42 days which resulted in scaphoid union in all patients.
Conclusion: This study demonstrated that non-vascularized bone grafting resulted in radiographic union of the scaphoid in all patients, including those with avascular necrosis. All participants regained the ability to perform daily hand activities without functional complaints. Complications occurred in 30.2% of cases, mainly presenting as mild pain and minor limitations in hand motion. These findings suggest that this technique is a safe and effective option for treating scaphoid non-union.
