 Mr. Sarkar, aged 25 years from Bangladesh presented to us in the clinic with complaints of painful, stiff hips with gross restriction of movements which we commonly call as fused hips. He found it extremely challenging to walk unnaded, to sit on a chair, to stand up from a sitting posture and to use the stairs. He was diagnosed with a condition called ankylosing spondylitis which is a chronic inflammatory disorder causing pain, stiffness, typically affecting the sacroiliac joints, the backbones and the hip joints. He had bilateral hip involvement with his left hip joint being more severely affected with hardly any movement along with the presence of rotational deformity and shortening of the limb. Following the medical and pre-anesthesia evaluation, a total hip replacement was performed wherein along with the soft tissue releases, the socket portion of the pelvis and the ball of the thigh bone are replaced with metal prosthesis. By doing so, we achieved painless mobility and function, deformity correction and significant improvement in lifestyle and posture. Mr. Tapas Sarkar presented to us with an inflammatory back pain which we see in a condition called ankylosing spondylitis. When he presented to us, he was in a bad shape, he already had a damaged hip and he was not even able to move around on his own. Ankylosing spondylitis is an inflammatory condition which affects younger economically productive population. This disease is managed medically and whenever medical management fails or whenever the patient has an advanced damage in his joints, we go for surgical management. In this patient also, by the time he reached us, he already had a bad hip damage which required surgical intervention and with total hip replacement, he dramatically improved and his results were amazing. In view of the restricted chest expansion in ankylosing spondylitis, there is an increased risk of post-operative pulmonary complications such as pneumonia and partial lung collapse which makes it imperative to have a well-equipped ICU backup team to handle these complications. Early detection, appropriate medical management and an active lifestyle goes a long way in reducing the severity of symptoms in ankylosing spondylitis.
