The radiological assessment of muscle properties-size, mass, density (also termed radiodensity), composition, and adipose tissue infiltration-is fundamental in muscle diseases. More recently, it also became obvious that muscle atrophy, also termed muscle wasting, is caused by or associated with many other diseases or conditions, such as inactivity, malnutrition, chronic obstructive pulmonary disorder, cancer-associated cachexia, diabetes, renal and cardiac failure, and sarcopenia and even potentially with osteoporotic hip fracture. Several techniques have been developed to quantify muscle morphology and function. Read More

Hip arthroscopy has been increasing tremendously in the past decade and is a very common surgical procedure to repair femoroacetabular impingement. To access the hip joint, distraction is mandatory to treat intra-articular disorders such as labral tears, cartilage loose bodies, and ligamentum teres tears and to evaluate the condition of the femoral head and acetabular cartilage. To distract the hip, counterdistraction is needed, and this is achieved with placement of a bulky and cushioned perineal post. Read More

American Hip Institute, Westmont, Illinois, U.S.A.

In the setting of true hip dysplasia, the high prevalence of intra-articular pathology may lead to recurrent symptoms and failure after periacetabular osteotomy (PAO). Femoral neck osteochondroplasty, microfracture, removal of loose bodies, and labral repair are examples of procedures that are performed with concomitant arthroscopy. When damage to the labrum is too severe to repair, reconstruction instead of extensive debridement before PAO can be more effective in restoring the labral seal to maintain joint lubrication and chondral protection.

Some proximal femur fractures may be treated surgically with the use of fracture fixation hardware such as the sliding hip screw and its variants. These devices allow the femoral head and neck fragment to compress against the trochanteric or shaft fragment as the hip screw telescopes into the barrel of the side plate. We describe an unusual complication in which the hip screw disengaged in the opposite direction, migrated through the hip joint, and came to rest inside the pelvic cavity. Read More

Elderly patients undergoing both elective and nonelective hip arthroplasty contribute markedly to health care spending, and the current aging population is likely to require even more resources. Several national joint replacement registries show a lower risk of revision surgery in patients older than 75 years who received cemented femoral components compared with cementless implants for primary total hip arthroplasty. Despite a higher incidence of early periprosthetic femoral fracture, noncemented femoral components are being used with increasing frequency in elderly patients worldwide. Read More
