The in vivo assessment of the three-dimensional (3D) kinematics of the hip in patients with femoroacetabular impingement (FAI) under weight-bearing conditions has not been previously reported. We evaluated the pre- and postoperative hip kinematics of a 34-year-old man, with a cam-type FAI while squatting, using image-matching techniques with measurement of the rim-neck distance. Post-osteochondroplasty, the α-angle improved from 51.0° to 35.5° and the head-neck offset ratio from 0.04 to 0.23. Coxalgia during squatting disappeared, and the Harris Hip Score improved from 79 to 92 at 1 year post-surgery...

Scapholunate (SL) instability is the most common form of carpal instability. Imaging (especially radiography) plays an important role in the staging, management, and postoperative follow-up of SL instability. In the final stage of SL instability, known as scapholunate advanced collapse, progressive degenerative changes occur at the carpal level. The goals of this article are to review the surgical options available for addressing the different stages of scapholunate advanced collapse, along with an emphasis on normal postoperative imaging and complications associated with each surgical option...

Hutchinson-Gilford progeria syndrome, also known as progeria, is an extremely rare disorder with an incidence rate of 1 in 8 million. It occurs sporadically, and patients suffering from this syndrome usually exhibit premature ageing. It has an autosomal recessive inheritance with a slight male predominance. The affected children usually die early with an average life span of 13.4 years. The most common cause of death in such patients is a cardio-vascular abnormality such as myocardial infarction. We present a rare case of progeria in an 8-year-old boy who was diagnosed clinically and was referred to our department for a skeletal survey...

We report a case of a 23-year-old female with pain and fullness in the right popliteal fossa. An MRI scan demonstrated an ossified enhancing soft tissue mass. Evaluation of the resected specimen showed a high-grade extraskeletal osteosarcoma juxtaposed to the three zones of myositis ossificans. At 1-year follow-up the patient is alive and disease free. A review of the literature purporting to document such an association failed to demonstrate a single case in which an osteosarcoma and MO with its zonal architecture co-existed...

OBJECTIVES: To evaluate the diagnostic value of MR arthrography (MRA) in diagnosing instability of the LHBT in patients with rotator cuff tendon tear. MATERIALS AND METHODS: The MR arthrograms of 101 patients were retrospectively reviewed and correlated with arthroscopic findings as the standard reference. Images were evaluated for (1) the integrity of the LHBT, (2) the position of the LHBT (subluxation/dislocation on axial images, inferior displacement on oblique sagittal image) and (3) the integrity of the biceps pulley (SGHL, supraspinatus and subscapularis tendon adjacent to the rotator interval)...

OBJECTIVE: To evaluate the variability of clinical treatment and outcomes based on reporting of diabetic foot ulcer MRI findings of adjacent marrow T2 hyperintensity with normal T1 signal. MATERIALS AND METHODS: A retrospective review was conducted of 46 MRI examinations evaluating diabetic foot ulcers that demonstrated normal T1 marrow signal, but T2 marrow hyperintensity deep to the ulcer. The cohort was divided based on MRI report impressions into three groups; "osteitis without osteomyelitis" (OW), "osteitis but cannot exclude early osteomyelitis" (OCEO) and "early osteomyelitis" (EO)...

OBJECTIVE: The coracoglenoid ligament (CGL) forms part of the anterosuperior capsuloligamentous complex of the shoulder. Although it has received attention in the anatomical literature, it has not been investigated on imaging. The purpose of this study is to determine the percentage value and the interobserver agreement of identification and classification of the CGL on MR and MR arthrography (MRA) imaging. MATERIALS AND METHODS: Retrospectively, 280 MR and 150 MRA examinations were evaluated for detection of the CGL by two musculoskeletal radiologists...

OBJECTIVE: Severe mismatch between pelvic incidence (PI) and lumbar lordosis (LL) leads to extra anterior displacement of the gravity line. The objective of this study is to investigate whether femoral head retroposition is a separate compensatory mechanism responsible for the extra anterior displacement. SUBJECTS AND METHODS: Based on the values of PI and LL, 94 patients were divided into the PI-LL match group (PI-LL ≤ 0°), the mild PI-LL mismatch group (20°> PI-LL >0°), and the severe PI-LL mismatch group (PI-LL ≥ 20°)...

REVIEW
Julia Crim
Arthroscopic surgery for femoroacetabular impingement (FAI) is increasingly frequently performed. Initial reports were that complications were very low, but as experience has increased, a number of long-term complications, in addition to factors related to poor clinical outcomes, have been identified. This review describes the normal and abnormal postoperative imaging appearance of the hip after arthroscopy for FAI. Abnormalities discussed include incomplete resection or over-resection of the impingement lesion, heterotopic ossification, cartilage damage, chondrolysis, instability and dislocation, recurrent labral tear, adhesions, psoas atrophy, infection, and avascular necrosis...

Slipped capital femoral epiphysis (SCFE) is a common hip disorder in older children and adolescents, classically with medial and posterior slippage of the proximal femoral epiphysis. However, valgus SCFE is a very rare entity, where the proximal femoral epiphysis slips laterally and posteriorly. To our knowledge, valgus SCFE with magnetic resonance imaging (MRI) features of contralateral pre-slip has not yet been reported. We present a case of a 9 year old girl with symptomatic valgus SCFE on the left and asymptomatic contralateral pre-slip on the right with concurrent radiographic, sonographic, and MRI findings...

Omar M Albtoush, Marius Horger
Multiple ligaments are involved in avulsion injuries of the knee joint, including both anterior and posterior cruciate ligaments; however, avulsion injury of the posterior cruciate ligament is less frequently encountered than the anterior counterpart. Furthermore, avulsion of the femoral side of the posterior cruciate ligament is far less common than the tibial one.Femoral attachment avulsion fracture of the posterior cruciate ligaments has been reported in literature in adolescents, rarely in adulthood, and never before in elderly patients, showing an inverse relationship with advancement in patient age...

Combining bone allografts and vascularized fibular autografts in intercalary reconstructions after resection of bone sarcomas is of particular interest in young patients as it facilitates bone healing and union and helps reduce fractures. However, adverse events related to bone adaptation still occur. Bone adaptation is driven by mechanical loading, but no quantitative biomechanical studies exist that would help surgical planning and rehabilitation. We analyzed the bone adaptation of a successful femoral reconstruction after Ewing sarcoma during 76-month follow-up using a novel methodology that allows CT-based quantification of morphology and density...

OBJECTIVE: The magnetic resonance imaging (MRI) appearance of the anterolateral ligament (ALL) has been described. However, the appearance of this structure and injury, in the presence of anterior cruciate ligament (ACL) injury, is less well defined. We studied the incidence of injury to the ALL and the pattern of this injury on MRI. MATERIALS AND METHODS: Following Institutional Review Board approval, a retrospective study of 375 consecutive MRI studies was performed...

Approximately 3300 new primary bone tumors will present to American physicians this year. This small but important group of malignancies has become more defined with developments in pathologic morphology, immunohistochemistry, and molecular studies. As tumor types are better partitioned, their specific characteristics are more readily observed. In this article we present the first reported case of a myxofibrosarcoma of bone developing within a bone infarct. With improved delineation of rarer tumor types, it is expected that additional cases of myxofibrosarcoma of bone will be recognized, potentially arising from a bone infarct...
