Outcomes of Three Corner Fusion Without Triquetrum Excision Versus Conventional Four Corner Fusion in SNAC Wrist

Scaphoid Fracture Clinical Trial

Official title:
Functional Outcomes of Three Corner Fusion Without Triquetrum Excision Versus Conventional Four Corner Fusion in Scaphoid Non Union Advanced Collapse (SNAC) Wrist Grade II and III : a Prospective Randomized Controlled Trial

Clinical Trial Summary

The investigator compare two types of limited wrist arthrodesis used for management of cases with scaphoid non union advanced collapse (SNAC) as regard the outcome to provide the most suitable technique

Clinical Trial Description

There is a controversy regarding the suitable limited wrist arthrodesis technique for SNAC wrist grade II and III . For several decades , scaphoid excision and four corner fusion (between lunate , capitate , hamate and triquetrum) was the gold standard with good functional outcomes . Later on , a more limited fusion technique was described , three corner fusion ( between lunate , capitate and hamate) with scaphoid and triquetrum excision to improve ulnar deviation range . On the other hand , biomechanical studies mentioned that the triquetrum had a certain proprioceptive function that could be affected when it was included in the fusion process .Furthermore , if the triquetrum was excised the radiolunate contact pressure would increase with higher risk of development of arthritis. The aim of the study to compare the conventional four corner fusion with three corner fusion with triquetrum excision ;
