“…Brunner et al [13] have already evaluated a CT-based navigation protocol for improving the accuracy of arthroscopic osteochondroplasty in impingement patients. Although the navigational system itself is highly accurate, the authors concluded that it does not improve the rate of insufficient alpha angle corrections after hip arthroscopy (24%).…”

Several theoretical models have shown that the range of motion of the hip joint is impaired in patients with femoroacetabular impingement, and that the acetabular cartilage is at risk of being damaged as a result of abnormal shear stresses, even during normal everyday activities. Computer aided technologies might add to the early diagnosis and adequate treatment of such lesions. This paper describes the technique, theories and algorithms we have developed for patient-specific detection, analysis and computer aided surgery of femoroacetabular impingement.Currently available models applicable to femoroacetabular impingement offer modeling based on collision analysis of a constrained hip joint. Such an approach implies that neither the femur nor the acetabulum can be analyzed completely separately for the presence of structural lesions responsible for the impingement problem. Moreover, a constrained model does not allow for comprehensive prediction of the possible locations and extent of secondary cartilage lesions (so-called contre-coup lesions) of the posterior acetabulum opposite the anterior impingement site. We report a new technique for the subject-specific morphological analysis of the proximal femur, acetabulum and hip joint. The technique offers a number of advantages compared to currently used techniques for the diagnosis and evaluation of hip impingement, and has direct orthopaedic applications as it allows computer aided planning and minimally invasive surgery for patients with femoroacetabular impingement.

“…Of these, five reported outcomes for both CAM and Pincer radiographic outcomes in the same study [20,25,26,29,31]. Three studies included magnetic resonance imaging (MRI) as part of their postoperative imaging protocol [22,26,31], while three other studies utilized computed tomography (CT) scan as part of their postoperative imaging protocol [27,29,32]. Table 2 shows radiographic outcomes for the included studies.…”

Femoroacetabular impingement (FAI) is a condition increasingly being recognized as a cause of hip pain and disability. Hip arthroscopy is a common method used to treat this condition. The purpose of this review was to identify reported radiographic outcomes after arthroscopic surgery for FAI. Online databases (PubMed, EMBASE, and Medline) were screened for studies involving arthroscopic management of FAI. Full-text reviews of eligible studies were conducted. We identified 23 eligible studies involving 1348 patients from an initial screen of 1304 studies involved. There were 15 different radiographic parameters among the 23 studies. The most commonly reported radiographic outcomes included the alpha angle (69.6 %), center edge angle (34.7 %), and femoral offset ratio (17.4 %). This study highlights the significant variation in reported radiographic outcomes after arthroscopic FAI surgery.

“…Various radiographic indices calculated on plain X-rays [standing AP pelvis, elongated-neck lateral view (Dunn lateral radiograph), and false profile], such as Tonnis OA grade, coronal CE angle, Tonnis angle, and variables derived from the three-dimensional CT scan (alpha-angle, beta-angle, McKibbon indices, acetabular version, coronal and sagittal CE angle, neck-shaft angle, and femoral version), which better delineates the bone anatomy, can facilitate the mechanical diagnosis, and specifically whether there is a structurally normal, undercovered, or overcovered hip (Figs. 1, 8, and 9) Computer navigation surgical planning software can be used to confirm and model osseous impingements [12,36]. These resultant mechanical stresses lead to reactive hip pain related to insufficient congruency or impingement between the head and socket, leading to asymmetric wear of the chondral surfaces of the acetabulum and femoral head with or without associated instability of the hip.…”
