ABSTRACT
Objective To investigate the value of external fixator in the treatment of posttraumatic elbow stiffness.Methods From January 2007 to December 2009,25 patients with posttraumatic elbow stiffness received surgical arthrolysis with assistance of external fixator.There were 10 patients with grade 1 stiffness,12 patients with grade 2 stiffness and three patients with grade 3 stiffness.The range of motion (ROM) was 0°-75° ( average 33.4°) preoperative,with < 30° in 12 patients.For the patients with grade 1 stiffness,intraoperative distraction with an external fixator rather than open arthrolysis was performed ; for the patients with grade 2 stiffness,the heterotopic ossification was removed through a limited approach before the external fixator was applied; for the patients with grade 3 stiffness,additional osteotomy and internal fixation before arthrolysis were performed.After operation,there was a rehabilitation phase,followed by mobilization of the elbow joint under protection of the external fixator for a mean period of six weeks.Results The intraoperative mean ROM was 105.6°,which was significantly improved than that before operation (P <0.05).The maximal flexion degree was above 110°in all patients.No instability occurred.Two patients were excluded from the follow-up:one had ulna fracture two weeks after operation due to an incorrect placement of the pin,and additional internal fixation was then carried out;another patient had numbness in the ulna side when flexed the elbow after arthrolysis,and the ulna nerve transposition was performed through another operation.Other patients were followed up for a mean period of six months.At the latest follow-up,the mean ROM was 97.4°( range,70°-130°),significantly improved than that before operation (P < 0.05 ),and lest 8.2°on average (0°-15 °) compared with the intraoperative ROM (P > O.05).The maximal flexion in all patients was above 100° Conclusion With the advantages of minimal invasive or noninvasive,indirect capsular traction,stability maintenance during the movement,and prevention of the motion loss during the rehabilitation,arthrolysis of the elbow joint with the use of external fixation frame can be a good alternative in the treatment of posttraumatic elbow stiffness.
