Abstract:
OBJECTIVE:To summarize the effectiveness of Kirschner wire buckling combined with bone fixation in the treatment of metacarpal avulsion fracture.
METHODS:The clinical data of 35 patients of metacarpal avulsion fracture admitted between March 2017 and June 2022 were retrospectively analyzed. There were 22 males and 13 females; the age ranged from 20 to 55 years, with an average of 31.6 years. There were 17 cases of the second metacarpal avulsion fracture, 6 cases of the fourth metacarpal avulsion fracture, and 12 cases of the fifth metacarpal avulsion fracture. The causes of injury included 21 cases of strangulation, 8 cases of sprain, and 6 cases of sports injury. X-ray film examination showed that the size of the avulsion fracture of metacarpal bone ranged from 0.30 cm×0.20 cm to 0.55 cm×0.45 cm. The total active motion (TAM) of the injured finger before operation was (154.00±17.38)°. The time from injury to operation was 3-10 days, with an average of 5.8 days. Follow-up regularly after operation, X-ray film and CT examination were performed to evaluate fracture healing and TAM of injured finger was measured. The finger function was evaluated by the trial standard of upper limb function evaluation of Hand Surgery Society of Chinese Medical Association.
RESULTS:All the incisions healed by first intention. All 35 patients were followed up 9-36 months, with an average of 28 months. All metacarpal avulsion fractures achieved bony healing, and the healing time was 4-6 weeks, with an average of 4.8 weeks. The metacarpophalangeal joint of the patient was stable, without stiffness, and the flexion and extension activities were good. At last follow-up, the TAM of the injured finger reached (261.88±6.23)°, which was significantly different from that before operation ( t=-35.351, P<0.001). The finger function was evaluated according to the trial standard of upper limb function evaluation of the Society of Hand Surgery of Chinese Medical Association, and 33 cases were excellent and 2 cases were good, with an excellent and good rate of 100%.
CONCLUSION:The treatment of metacarpal avulsion fracture with Kirschner wire buckling combined with bone fixation has the advantages of less trauma, firm fixation, and less interference to the soft tissue around metacarpophalangeal joints, which is a good alternative method for the metacarpal avulsion fracture.
