We present a case of multiple osteolytic lesions in a 28-year-old adult who presented with headache, back pain, and hip pain of 6 months. There was no history of localized swelling or rise of temperature, no history of weight loss or evening rise of temperature. On examination, there were no focal neurological deficits. Routine laboratory investigations, including total leukocyte counts, differential leukocyte counts, hemoglobin, and platelet counts, were within normal limits. There was a borderline elevation of erythrocyte sedimentation rate...

Locomotion task and speed changes affect dynamic joint function. Walking and running require different coordination patterns of lower extremity joint mechanics. These coordination differences can result in measurable changes in kinematic and kinetic patterns. When locomotion speed changes, the functional role and movement strategy of each joint is altered. A deeper understanding of joint level mechanics and functional interactions will benefit rehabilitation programs and assistive device development. In this study, joint stiffness, joint mechanical work and power were assessed, as they relate to dynamic function of joints during locomotion...

BACKGROUND: Generalized Joint Hypermobility (GJH) is suggested as a contributing factor for injuries in young athletes and adults. It is presumed that GJH causes decreased joint stability, thereby increasing the risk of joint and soft tissue injuries during sports activities. The aim of this study was to determine the correlation between the hypermobility rate (using the Beighton`s modification of the Carter-Wilkinson criteria of hypermobility) in gymnasts and injury rate, during the period of one year...

The aim of this study was to determine the medium to long term survivorship of the Birmingham Hip Resurfacing prosthesis in an independent series of young men. The medical records and radiographs of all men aged 55 and under who had undergone Birmingham hip resurfacing by the senior author were reviewed. Patients who had not attended recent follow-up or had been previously discharged were contacted by telephone. Between 1999 and 2011 a total of 147 hips were resurfaced in 155 patients (mean age 47 years (19 to 55)) with minimum 5 year follow-up (mean 8...

While many femoral neck fractures can be reliably treated with surgical intervention, Pauwels III femoral neck fractures in the young adult population continue to be a challenging injury, and there is no consensus on optimal treatment. As such, there are past and ongoing biomechanical studies to evaluate the fixation provided by different constructs for this inherently unstable fracture. While many investigations rely on cadavers to evaluate the biomechanical performance of a construct, significant inter-subject variability can confound the analysis...

Does imaging of the pelvis using a set of radiographs and computed tomography (CT) cause cancer? A computer-based simulation study using 5 different imaging and radiation dose protocols has calculated the lifetime risk of malignancy for young adults for pelvic radiographs and CT scans. The cumulative lifetime-attributable risk of cancer was 0.2% for males and 0.35% for females. This appears low but the numbers needed to harm were 952 for males and 564 for females. However, the authors have based their calculations on the linear no-threshold model, which is controversial, and a linear relationship between dose and risk may not exist...

Estimated lifetime risk of an osteoporotic fracture in men over the age of 50 years is substantial and lifestyle factors such as physical activity may explain variation in bone mass and bone loss associated with aging. Men (n = 253) aged 20-66 years were followed for 7.5 years and factors that influence changes in means and rates of change in bone mass, density, and size using dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) were investigated; in particular, seasons of sports participation during high school and college...

BACKGROUND: Increased mechanical load secondary to a large body mass index (BMI) may influence bone remodeling. The purpose of this study was to investigate whether BMI is associated with the morphology of the proximal part of the femur and the acetabulum in a cohort of adolescents without a history of hip disorders. METHODS: We evaluated pelvic computed tomographic (CT) images in 128 adolescents with abdominal pain without a history of hip pathology. There were 44 male patients (34%) and the mean patient age (and standard deviation) was 15 ± 1...

BACKGROUND: Hip resurfacing arthroplasty (HRA) is an alternative to total hip arthroplasty (THA) for the treatment of hip osteoarthritis in patients younger than 50 years. Data on revision rates after HRA are conflicting. The National Institute for Health and Care Excellence (NICE) recommends performing only those hip arthroplasty procedures associated with 10-year revision rates no greater than 5% (0.5% per year). Follow-up studies can rapidly determine whether this criterion is met...

BACKGROUND: Multiple Ephiphyseal Dysplasia (MED) is a rare autosomal dominant skeletal dysplasia that causes deformation of the epiphysis of the involved joints. The hips are invariably affected and symptoms due to incapacitating early onset degenerative hip disease often begin between the second and fourth decade of life. Literature regarding the clinical and radiographical outcomes after total hip arthroplasty in this young population are very scarce. HYPOTHESIS: In patients with multiple epiphyseal dysplasia and early onset degenerative hip disease, hybrid total hip arthroplasty is a safe and reliable procedure...

Metal-on-metal bearings for total hip replacements have been introduced as an alternative to polyethylene in young and more active patients. These have, however, been shown to be prone to implant malpositioning and have been limited by some specific design features. In that context, coatings present an option to increase wear resistance by keeping the high fracture strength of the metal substrate. A custom-made electroplating setup was designed for the coating of CoCr substrates using (a) an industrial standard chromium electrolyte; (b) a custom-made hexavalent chromium (Cr6+) electrolyte with a reduced chromium trioxide (CrO₃) content, both without solid additives and (c) with the addition of fullerene (C60) nanoparticles; and (d) a trivalent chromium (Cr3+) electrolyte with C60 addition...

The hip rotator cuff tear usually develops in the middle-aged through gradual degenerative changes, similar to rotator cuff tears in the shoulder. An acute tear in the hip abductor by a traumatic event in young ages is very uncommon. The authors experienced an unusual case of an acute traumatic tear isolated to the gluteus medius in a young male; thus, we report the treatment results in this rare case with a review of the literature.

Atypical insufficiency fracture of the femur following prolonged bisphosphonate use is well described. Regardless of the cause, insufficiency fracture of the acetabulum is extremely rare, and no reports have described insufficiency fractures of the acetabulum that are associated with prolonged bisphosphonate use. This report demonstrates the possibility of insufficiency fracture at the acetabulum following long-term alendronate use and the necessity of particular care in managing insufficiency fractures in "frozen" bone...
