“…[3][4][5][6][7][8] In this unusual ankylosis the head of femur was completely ossified and fused with the hip bone with a reverse position (femur upper end facing downwards and lower end facing upwards) such ankylosis of hip joint has not been cited in the recent medical literature. Hence, knowledge of such abnormalities should be kept in mind for orthopaedic surgeons and radiologists when planning the different surgical approaches.…”

Background: The hip joint is the body’s second largest weight-bearing joint forms a connection from the lower limb to the pelvic girdle. It is formed by an articulation between the pelvic acetabulum and the head of the femur. Ankylosis or fusion of the joint, ossification of the adjacent ligaments and calcific tendinitis of adjacent muscles can decrease the mobility of the joint. The study was undertaken to evaluate the incidence of abnormal ossified structures around the hip joint.Methods: This study was carried out on 228 dry human hip bones (right- 114 and left-114) and 228 dry human femur bones (right- 114 and left-114) irrespective of age and sex at Varun Arjun medical college-Banthra, UP, KMCT Medical College, Manassery-Calicut and Melaka Manipal Medical College-Manipal. All the hip and femur bones were macroscopically inspected for the abnormal ossified structures around the pelvic acetabulum and upper end of the femur. Photographs of the abnormal ossified structures were taken for proper documentation.Results: Very rare and unusual unilateral ossified and complete fused left hip joint was noted (0.43%). Unilateral ossified acetabular labrum with ossified transverse acetabular ligament was noted in seven right hip bones (3.07%). Unusual ossified fibrous capsule on the posterior aspect of neck of femur was noted in 4 left sided femur bones (1.75%). Unusual unilateral ossified deposits near the greater trochanter and intertrochanteric line of femur was noted in nine left sided femur bones (3.94%).Conclusions: Anatomical knowledge of ankylosis of hip joint, ossification of the ligaments and muscles tendons around the hip joint as found in the present study made this study unique such abnormal ossifications may be helpful for clinicians, radiologists and surgeons for differential diagnosis and can be implicated in the development of innovative treatments of hip joint and hip pains.

“…For the patients with advanced hip involvement and presenting pain with functional impairment, THA is currently treatment of choice [3,4]. Some problems may be encountered after THA, such as unpredictable gain in range of motion [24,25] and high incidence of HO [9]. The prevalence of class III and IV HO ranged from 11% to 36% in various studies [3,4,[8][9][10].…”

“…Symptoms related to the adjacent joints become intrusive only after a lapse of 20 to 30 years. 10 Conversely, with a malpositioned fusion, pain related to degenerative changes in the neighbouring joints develops more rapidly. 4,24 There have been several reports of the conversion of ankylosed knees 9,15-21,24 or hips 1,3-5,8,10,11,13,14,25 to total joint replacement.…”
