상완 신경총 손상에서 Steindler 주관절 굴곡 성형술
Purpose: The purpose of this study was to analyze the clinical results after Steindler flexoplasty.
Materials and Methods: We analyzed 6 cases who had nearly normal finger and wrist joint flexion function, but could not flex elbow joint actively because of upper arm type brachial plexus injury. We performed operation during the period from February 1997 to July 2003. There were 5 males and 1 female with mean age of 28 years (range: 19~51 years) when Steindler flexoplasty was done. The average follow-up period was 3 years 11 months (range: 12 months~7 years 4 months). We assessed active range of motion of elbow joint, muscle power and elbow function by Mayer & Green grade scale at last follow-up. We assessed how much they were favorable for Steindler flexoplasty and had improvement of upper extremity function and correction of deformity.
Results: Postoperative, flexion range of elbow joint improved to average 111.7°( r a n g e : 90~130°). 25.8°(range: 15~45°) in flexion contracture and 16.6°(range: 10~35°) in pronation contracture were remained. Range of motion of elbow joint improved to average 85.3°( r a n g e : 4 5~1 0 5°). Flexion power of elbow joint improved to Grade 5 in all cases. Postoperatively on Mayer & Green grade scale, there were excellent in 3 cases(50%), good in 2 cases(33.3%), fair in 1 case(16.7%). On patient’s own assessment of functional improvement, there were excellent in 4 cases(66.6%), good in 1 case(16.7%) and fair in 1 case(16.7%).
Conclusion: Steindler flexoplasty can reserve good clinical results with being improved to active flexion of elbow joint in cases who have functional hand and wrist, but paralysis upper arm muscle in brachial plexus injury.
