Application of self-made mini external fixator in phalangeal fractures

Objective To explore the clinical effect of phalangeal fractures with self-made mini external fixator. Methods From June, 2014 to June, 2017, 16 cases of phalangeal fracture were treated with self-made mini external fixator. In the followed-up periods, the regulating rechecks of X-ray and measurement of interphalangeal joint activity were determined. The total active movement (TAM), numerical pain ranting scale (NPRS) and morning stiffness was used to estimate the fracture healing and the hand function recovery. Results Pain and abnormal movement around fracture was found 6 weeks after the operation in 1 case, which had been healed by removing the external fixation, open reduction and internal fixation with kirschner wire. The other 15 cases were followed-up of 48-72 (average, 58) weeks. The fracture has healed. And there was no osteomyelitis, no breakage and loosening of steel needles. The clinical healing time of the fracture was 14 to 16 weeks, with an average of 15.5 weeks. According to the TAM, NPRS and morning stiffness, there was excellent in 11 cases, and good in 4 cases. Conclusion The self-made mini external fixator can maintain the stability after fracture reduction, provide the tension required for the healing of collateral ligament and joint capsule, and meet the need of early functional exercise. It is an ideal treatment option for phalangeal fractures. Key words: Phalangeal fracture; External fixator; Self-made; Repair
