Prediction Of Abductor Lurch After Open Reduction And Pelvic Osteotomy For DDH (Developmental Dysplasia Of The Hip)
Main Article Content
Abstract
Objective: In this study, we sought to evaluate surface electromyography (sEMG) signal attributes of peri-hip muscles after Pemberton osteotomy in children with unilateral developmental dysplasia (DDH) of the hip.
Methodology: The DDH group consisted of 25 children with unilateral DDH who underwent Pemberton osteotomy, and the benchmark group consisted of 25 healthy children of approximately the same age. When the two groups of children underwent her sEMG test, the bilateral gluteus maximus, rectus femoris, mean top of the hamstring, and tensor her belt top root mean square (RMS) were recorded.
Results and Findings: Normal postoperative follow-up in the DDH group was 29.79 ± 27.33 weeks. Compared to the control group, the DDH group had significantly smaller mean RMS values of the affected hamstring muscles (P<0.05) and significantly greater mean RMS values of the reverse tensor femoris muscle during walking. was significantly larger than one. Affected gluteus maximus when remaining in DDH group (P<0.05).
Conclusion: sEMG exercises of peri-hip muscles in children with unilateral DDH who underwent femoral osteotomy and matching Pemberton osteotomy showed imbalance and compensatory stretching during standing and walking field. The hip muscles' rehabilitation program must be strengthened following unilateral DDH.
