Isolated,extra-articular neck and shaft fractures of the 4th and 5th metacarpals: a comparison of transverse and bouquet (intra-medullary) pinning in 67 patients
Although extra-articular metacarpal fractures are common, there is no consensus on the mode of treatment. We evaluated the outcome in 67 patients operated for isolated, extra-articular fractures in the neck or shaft of the ulnar two metacarpals 28 months post-operatively. There were 22 bouquet (intra-medullary) pinnings and 45 transverse pinnings; 11 were lost to follow-up. Overall, hand function was good, and no difference was detected between the two methods (QuickDASH, grip strength, range of motion, VAS pain and VAS satisfaction). Many patients suffered complications: 12% had a superficial infection (all treated with transverse pinning with wires left exposed); 39% had some impairment in skin sensation; 29% reported cold intolerance; and 10% had other complications. Due to the potential risk of a secondary fracture of the neighbouring metacarpal after transverse pinning, we recommend bouquet (intra-medullary) pinning. We also recommend burying wires beneath the skin surface to avoid infection.
