Three-point Kirschner wire fixation combined with wire compression for the treatment of metacarpal neck fractures
Objective To investigate the clinical efficacy of three-point Kirschner wire fixation combined with wire compression in the treatment of metacarpal neck fractures.Methods From January 2015 to January 2022,13 patients(13 fingers)with metacarpal neck fractures were treated with three-point Kirschner wire fixation combined with wire compression.There are 11 males and 2 females in this group of patients.The age range was 16 to 60 years old,with an average of 38 years old.5 cases were injured by collisions,4 cases were injured by heavy objects,and 4 cases were injured by impacts.There were 3 cases of open injuries with 3 fingers,and 10 cases of closed injuries with 10 fingers.There were 2 cases of the third metacarpal bone,4 cases of the fourth metacarpal bone,and 7 cases of the fifth metacarpal bone.Results All 13 patients in this group had primary wound healing,without complications such as infection or skin soft tissue necrosis after surgery.All patients were follow-up after surgery for 4 to 16 months,with an average of 7.5 months.All metacarpal fractures in this group had bone healing,without malunion,nonunion,loosening or fracture of internal fixation,and no obvious signs of traumatic arthritis.According to the trial standard of upper limb function evaluation issued by Hand Surgery Society of Chinese Medical Association,9 cases were excellent,2 cases were good,2 cases were fair.Conclusion The combination of three-point Kirschner wire fixation and wire compression is a reliable method for treating metacarpal neck fractures,with definite and satisfactory results.
