Background: Scaphoid nonunion remains a challenging problem for hand surgeons. In this study, we assessed the functional outcome of scaphoid nonunion treatment and the influence of a number of variables on it.
Methods: In this study we recruited 24 patients with scaphiod nonunion by consecutive sampling at Dr. Ali Shariati Teaching Hospital, in Tehran, Iran in 2008-2011. We examined the patients by antero-posterior (AP) and lateral view radiographies and wrist MRIs. Functional outcome of surgery was scaled according to Mayo wrist and Quick DASH scoring systems.
Results: Among 10 cases with osteonecrosis, there were 7 (70%) cases of radiological union. In 13 (92%) out of 14 cases who had no signs of osteonecrosis, we radiologically confirmed scaphoid union after the treatment. The total union rate was estimated to be 83% at the end of 24 months follow up (P<0.05).
Conclusion: The results showed that patients with scaphoid nonunion have improved function after surgical treatment.
