Brief Summary:
The treatment for scaphoid proximal pole nonunion remains challenging due to the poor vascularity in the proximal pole fragment associated SL injury and the technique of fixation Vascularized bone grafts and non-vascularized iliac bone graft have been used in patients with scaphoid proximal pole nonunion but the indication has not been well clarified Alternatively we have been treating such patients with vascularized bone graft or non-vascularized bone graft with screw or k-wire fixation with considerable success The purpose of this study is to evaluate and analyze retrospectively the surgical efficacy of our procedure
Detailed Description:
Scaphoid nonunion are common and operative treatment with bone graft was reported to have good result However the treatment for proximal pole nonunion remains controversial There are some patterns of pathoanatomy combined with scaphoid fracture like SL ligament tears which could not be easily identified or treated initially The proximal pole nonunion was near SL joint Therefore proximal pole nonunion may result in DISI instability Furthermore proximal pole nonunion was identified as a poor prognostic factor in scaphoid nonunion
In the past 10 years we have some different technique like VBG arthroscopic bone graft to achieve good results Some studies revealed that significantly better SL stability was achieved with ARASL We also used ARASL with BG to improve proximal pole union However it is not clear which method would be appropriate for proximal pole nonunion We retrospectively investigated the functional outcome and radiological results after at least 2-year follow-up to clarify the surgical efficacy of these procedures
