Abstract

Introduction: An articular fracture of the base of the thumb metacarpal consisting of a single, variable-sized, volar-ulnar fracture fragment is termed Bennett fracture. In the studies conducted so far there has been paucity in the knowledge about the methods of k wire fixation for the Bennett fracture and hence the purpose of this study is to compare functional outcome between the trans – 2nd metacarpal fixation and trans – trapezius fixation with K wire for Bennett fracture.
Methods: Patients were 18 years and above with no previous injury on the 1st metacarpal . Final assessment was performed from six months to nine months after the treatment with the DASH Score, VAS scale for pain, Hand Grip strength by Dynamometer. Radiographic images were taken at 6 months post-op in two separate views to evaluate post-traumatic arthritis of the first CMC joint.
Results: Statistical analysis showed a correlation between Pain and DASH score to be 0.946 in TTZ group and 0.966 in T2MC group and hence signifies that patients in T2MC group had a better functional outcome with lower DASH score and lower pain score. Significant correlation was seen between Pain and Grip strength, with -0.587 in TTZ group and -0.482 in T2MC group. Higher pain score correlated with higher DASH score and lower Grip strength and hence we can conclude that T2MC had a better functional outcome post-surgery than TTZ technique of fixation. Post op radiographs showed that T2MC group of patients had a better outcome with less arthritic complications and less pain and better grip strength.
Conclusion: This study gives us the overview about the two fixation methods of Bennett fracture , and that when trans 2nd metacarpal fixation is done , there are less chances of arthritis of the CMC joint as well as better functional outcomes post operatively as compared to trans trapezial fixation and hence guides a surgeon to make a decision about the technique of fixation to be employed during fixing such fracture.
