Comparative Gait Analysis: Gait Parameters in Pre- And Post-Operative Developmental Dysplasia of the Hip

Objectives: To compare the pre-and post-operative gait patterns in developmental dysplasia of the hip (DDH) undergoing corrective surgery. Materials and Methods: This prospective observational study was conducted at the Department of Anatomy in collaboration with the Department of Orthopedic and Traumatology, Khyber Teaching Hospital Peshawar, and Pakistan Institute of Prosthetics and Orthotics (PIPOS) laboratory, Hayatabad Peshawar from March 2018 to March 2019. Patients were examined clinically and radiologically, and pre-operative gait analyses were done. Three months postoperatively, the second gait analysis was repeated. Data was analyzed through SPSS-23 using one-way ANOVA. Results: The mean age of study participants was 6 years.Clinically all patients were positive for trendelendberg test, limping of lower limb and lower limb discrepancy.Radiologically there was no significant correlation between age and Tonnis(Chi square test). The range of motion for each joint; hip, ankle and knee was calculated for deviation from standard of 50,30 and 70 degree foreach joint respectively. The results were tabulated as fl exion and dorsifl exion (+), extension andplantar flexion (-) from the standard. Post-operatively the hip joint showed hyperextension deviation24.83 ± 6.84 while the knee joint and ankle joints demonstrated fl exion/plantardeviationof 5.85 ± 68.57and22.89 ± 42.52 respectively. In this study, there is negative correlation betweengate parameters and range of motion (p-value=0.003). Conclusion: In the pre and post operative comparison in gate parameters there were three parameters post trunk,post valgus/varus and post stance are signifi cant P value is less than 0.05.
