自制微型外固定支架在指骨骨折中的应用

Application of self-made mini external fixator in phalangeal fractures

目的探讨应用自制微型外固定支架治疗指骨骨折的临床效果。方法自2014年6月至2017年6月,应用自制微型外固定支架治疗指骨骨折16例。术后定期随访,复查X线片,测量指间关节活动度。根据手指总的主动活动度(TAM)、疼痛数字评分表(NPRS)、晨僵3个指标评估患者骨折愈合情况和功能恢复情况。结果本组16例中有1例术后6周复查时,骨折端仍有压痛和异常活动,予拆除外固定支架,切开复位克氏针固定后愈合。其余15例随访48~72周,平均58周,骨折愈合,未出现骨髓炎、钢针断裂及松动。骨折临床愈合时间14~16周,平均15.5周。根据TAM、NPRS系统和晨僵进行评定:优11例,良4例。结论自制微型外固定支架适用于指骨骨折的治疗。它能够维持骨折端的稳定性,提供关节侧副韧带及关节囊所需的张力,可以实现早期功能锻炼的目的,是一种较为理想的治疗方法。

ObjectiveTo explore the clinical effect of phalangeal fractures with self-made mini external fixator. MethodsFrom 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. ResultsPain 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. ConclusionThe 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.
