Abstract: Objective: To evaluate the treatment modality by CE angle of Wiberg in various Hip joint pathologies.
Method: This is a non-Randomised Prospective, observational study carried out at Department of Orthopaedics, Index medical college hospital and research centre, Indore (M.P.) during the period of 15 months from January 2018 to March 2019. Ethical clearance taken by Ethical Committee. In this study 35 hips of 28 patients who fulfilled our inclusion criteria were included. In our study patients with hip pathologies with age more than 5 years of both genders, hip pathologies like CAM and/or Pincer type of Femoroacetabular impingement, Acetabular retroversion, Perthes like deformity, Osteoarthritis Hip, Avascular necrosis of femoral head, Developmental dysplasia of hip, Patients who are doubtful for hip preservation or salvage procedure, who were willing to provide their voluntary written informed consent were included. Patients with congenital hip pathologies were exclude. In this study, we assessed the CE angle of Wiberg, in various aspheric hip conditions and formulate a protocol for further management of these Hip pathologies.
Result: In this prospective study total 28 patients (35 Hips) of various hip pathologies 21 males (25 hips) 75% and 7 females (10 hips) 25% with age range of 5 years - 65 years with mean age of 41.32 ± 18.50 years out of which males were from 5 - 65 years with mean age 40.86 ± 20.44 and females were in the age range of 23 - 52 years with mean age 42.71 ± 12.04. Out of 28 patients 9 (32.14%) were FAI, 8 (28.57%) were OA hip, 8 (28.57%) were Avascular necrosis of Femoral head and 3 case (10.71%) is of Perthes' disease. In FAI cases 4(44.44%) patients were of Pincer type, 5(55.55%) were of Combined type with no any case of isolated CAM form. All were unilateral involvement with average CE angle of 32.67 ° ± 11.67 °. In Pincer type mean CE angle was 36.25 ° ± 7.5 ° while in combined form the mean CE angle was 29.8 ° ± 14.4 °. Out of 4 patients of Pincer FAI, 3 patients of Pincer type had CE angle between 25 - 40 ° which comes under normal range of CE angle so all were planned for non-operative management.
Conclusions: We have found that all the hip pathologies reported to us had spectrum of variations in CE angle depending on the severity of disease. Variation was maximum seen in Osteoarthritis and Femoroacetabular impingement, in the cases of FAI maximum were of Pincer type.
