  • Title: Closed intramedullary femoral osteotomy. Shortening and derotation procedures.
    Author: Chapman ME, Duwelius PJ, Bray TJ, Gordon JE.
    Journal: Clin Orthop Relat Res; 1993 Feb; (287):245-51. PubMed ID: 8448951.
    Abstract:
    Closed osteotomy and nailing were performed on 37 patients for leg-length inequality or rotational deformities. Shortening operations were performed in 31 patients, derotation in six. Preoperatively, the leg-length discrepancy ranged from 2 to 6.6 cm. All femoral shortenings resulted in correction to less than 1 cm. Preoperatively, rotational deformities averaged 58 degrees; all were corrected to within 5 degrees of normal. Follow-up observation averaged 3.3 years. There were no nonunions or infections. All patients regained preoperative joint range of motion (ROM). Thirteen patients were Cybex tested one year or more postoperatively; all had quadriceps and hamstring strength equal to or greater than the contralateral leg, except for two patients who had suffered additional trauma to the shortened femur. Closed femoral osteotomy is an effective, safe, and reproducible means to obtain lower limb length correction in patients with leg-length inequality or rotational abnormality.
