Radiographic Pincer Morphology Not Associated With Hip Osteoarthritis, Reveals Study
Radiographic Pincer Morphology Not Associated With Hip Osteoarthritis, reveals study published in the Arthritis Care and research.
The objective of this study was to assess the relationship between pincer morphology and radiographic hip osteoarthritis (RHOA) over 2, 5, 8, and 10 years’ follow-up and to study the interaction between pincer morphology and pain. Individuals from the prospective Cohort Hip and Cohort Knee study were drawn. Anteroposterior pelvic and false profile radiographs were obtained. Hips free of definite RHOA (Kellgren and Lawrence [KL] grade 0 or 1) at baseline were included. Pincer morphology was defined as a lateral or anterior center edge angle or both ≥40° at baseline. Incident RHOA was defined as KL ≥ 2 or total hip replacement at follow-up. Multivariable logistic regression with generalized estimating equations estimated the associations at follow-up. Associations were expressed as unadjusted odds ratios (ORs) and adjusted ORs with 95% confidence intervals (CIs).
An interaction term was added to investigate whether pincer morphology had a different effect on symptomatic hips. Results: Incident RHOA developed in 69 hips (5%) at 2 years’ follow-up, in 178 hips (14%) at 5 years’ follow-up, in 279 hips (24%) at 8 years’ follow-up, and in 495 hips (42%) at 10 years’ follow-up. No significant associations were found between pincer morphology and incident RHOA (adjusted OR 0.35 [95% CI 0.06–2.15]; adjusted OR 1.50 [95% CI 0.94–2.38]). Significant interactions between pain and anterior pincer morphology in predicting incident RHOA were found at 5, 8, and 10 years’ follow-up (OR 1.97 [95% CI 1.03–3.78]; OR 3.41 [95% CI 1.35–8.61]). No associations were found between radiographic pincer morphology and incident RHOA at any follow-up moment. Anteriorly located pincer morphology with hip pain, however, was significantly associated with incident RHOA. This highlights the importance of studying symptoms and hip morphology simultaneously.
