Abstract
Introduction
Improved understanding of the pathomechanics associated with hip osteoarthritis has heightened interest in joint preservation surgery. Nevertheless, the specific disease patterns associated with hip degeneration are not completely understood. The purpose of this study was to define the etiologies of premature hip joint deterioration and to characterize the structural abnormalities associated with secondary osteoarthritis.
Methods
We reviewed 730 hips treated with primary total hip arthroplasty in patients younger than 50 years. Clinical and radiographic records were examined to define the etiology of disease and to characterize structural anatomy.
Results
Of 730 hips, 54% were in men, and 46%, in women. Average age was 40.2 years. Two hundred twenty (30.1%) had osteonecrosis; 48 (6.6%), posttraumatic disease; 37 (5.1%), inflammatory arthritis; 405 (55.5%), osteoarthritis; and 20 (2.7%), inadequate radiographs. Of the 405 osteoarthritic hips, 181 had DDH; 32, Perthes; 21, SCFE; 6, postsepsis; and 165, osteoarthritis of unknown etiology. An indepth radiographic analysis was then performed on these 165 hips: 78 had radiographic findings consistent with cam impingement (reduced head-neck offset, aspherical femoral head), 10 with pincer impingement (retroversion or coxa profunda/protrusio), and 40 with combined cam/pincer impingement. Thirty-seven had no obvious structural abnormality, or disease was too advanced for interpretation.
Discussion
This study indicates that secondary osteoarthritis and osteonecrosis are the major mechanisms of premature hip joint degeneration. For osteoarthritis cases with an unknown etiology, these data indicate that hip impingement disorders are the most common cause of secondary osteoarthritis.
