Kinetic and Kinematics Parameters of Hip in Gait for a Congenital Longitudinal Tibial Deficiency with Orthoprosthesis and Transfemoral Prosthesis: A Case Study

Introduction: Congenital longitudinal tibial deficiency is a rare condition. It is characterized by partial or complete absence of tibia with a relatively intact fibula. Its standard treatment is surgery and employing orthoprosthesis or prosthesis. However, the effects of gaits according to the types of prosthesis is barely known. Methods: Orthoprosthesis is offered to a 30-year-old man experiencing left-side congenital type 1 tibial hemimelia (classified as Jones type 1B) deficiency with thoracolumbar scoliosis and exhibiting a depressed shoulder as well as a stiff knee. He decided to have an amputation to wear a transfemoral (TF) prosthesis comprising a microprocessor-controlled knee. Results: Three-dimensional gait analyses and a 6-minute walk test were performed preoperatively and postoperatively with the orthoprosthesis and TF prosthesis. Furthermore, the kinematics of hip flexion/extension and pelvic anterior/posterior tilt range of the motion degree were increased using TF prosthesis. The result of the kinetics of the hip flexion/extension moment and hip power parameters were affected using the TF prosthesis. Conclusions: This case study suggests that the new prosthesis provides removable and adaptable component; further, it delivers a comfortable sitting experience because of its new socket design and knee joint flexion. Clinical Relevance: Patient satisfaction is better with TF prosthesis than with orthoprosthesis. TF prosthesis is more cosmetic than orthoprosthesis, provides a symmetrical gait pattern, decreases donning and doffing durations, and there is no uncomfortable protrusion when sitting (due to amputation of the foot and leg part).

Automated summary

The study suggests that using a TF prosthesis can increase the range of motion of the hip joint, improve kinetics and power parameters, enhance comfort and adaptability, and patients are more satisfied with the TF prosthesis.
