Application of New Combined Ortho-prosthesis to Severe Leg Length Inequality: A case report

ABSTRACT

We presented a case which showed clinical improvements after fabricating new ortho-prosthesis to a patient with severe leg length inequality. He was 51 years old and had developed the leg length inequality on the right due to osteomyelitis that he experienced when he was seven. He had been using the orthosis fabricated by a private orthotic shop for more than twenty years from his twenties. We prescribed a new ortho-prosthesis composed of patellar tendon bearing ankle foot orthosis combined with endoskeletal shank and dynamic SACH foot. With this new ortho-prosthesis, there were significant improvements in initial abnormal gait patterns of excessive knee flexion at mid-stance and decreased maximal knee flexion peak at swing phase in the kinematic parameters on transverse plane. And step width, step length and step time were also improved. He got pain relief and improvement of gait endurance
