We report the case of a two and a half-year-old girl who presented with injury to the right thigh along with a discharging sinus in the midthigh region following a nonorthopaedic surgical procedure. Radiographs of the thigh indicated osteomyelitis of the femoral diaphysis with pathological fracture. During follow-up examination, shortening was observed in the affected limb, along with complete separation of the femoral epiphysis with partial resorption of the femoral head. A few cases of physeal separation of the femoral head following osteomyelitis of the femoral diaphysis have been reported in the published literature, but still it may go undiagnosed until late stages because of the lack of awareness among orthopaedicians about this entity...

BACKGROUND AND AIMS: Extravasation of irrigation fluid used in shoulder arthroscopy can lead to life-threatening airway and systemic complications. This study was conducted to assess the effect of irrigation fluid absorption on measurable anthropometric parameters and to identify whether these parameters predict airway/respiratory compromise. METHODS: Thirty six American Society of Anaesthesiologists physical status one or two patients aged 15-60 years undergoing shoulder arthroscopy under general anaesthesia were recruited...

Verbal instructions play a key role in motor learning and performance. Whereas directing one's attention toward bodily movements or muscles (internal focus) tends to hinder performance, instructing persons to focus on the movement outcome, or an external object related to the performed task (external focus) enhances performance. The study's purpose was to examine whether focus of attention affects maximal force production during an isometric midthigh pull (IMTP) among 18 trained athletes (8F & 10M). Athletes performed 3 IMTP trials a day for 3 consecutive days...

INTRODUCTION: Muscle is strongly related to cortical bone architecture in children; however, the relationship between muscle volume and trabecular bone architecture is poorly studied. The aim of this study was to determine if muscle volume is related to trabecular bone architecture in children and if the relationship is different than the relationship between muscle volume and cortical bone architecture. MATERIALS AND METHODS: Forty typically developing children (20 boys and 20 girls; 6 to 12y) were included in the study...

BACKGROUND: Whole-body magnetic resonance imaging (MRI) is the gold standard for the assessment of skeletal muscle (SM) and adipose tissue volumes. It is unclear whether single-slice estimates can replace whole-body data. OBJECTIVE: We evaluated the accuracy of the best single lumbar and midthigh MRI slice to assess whole-body SM, visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT). DESIGN: Whole-body MRI was performed in 142 healthy adults aged 19-65 y [mean ± SD age: 37...

The efficacy of electrical muscle stimulation to restore motor function was investigated in fifteen males who described prior knee surgery/injury. Persisting strength imbalance between limbs related also to reduction in cross-sectional area of the affected quadriceps, as assessed by computed tomography of the midthigh. Subjects underwent a four-week programme of daily electro-motor stimulation with repeated assessment of force production by the knee extensors, correlated with surface electro-myography. Results showed no change in quadriceps cross-sectional area over the course of the study, however, significant improvements in force production for both limbs were achieved, accompanied by alteration in motor unit activity patterns to suggest that neural efficiency of motor unit activation (synchronization) may account for the improvements, as opposed to a marked morphological contribution...

CONTEXT: In adults with Prader-Willi syndrome (PWS), abnormal body composition with decreased lean body mass and skeletal muscle (SM) volume has been related to altered GH secretion and may possibly contribute to greatly reduced motor capacity. OBJECTIVE: The scope of the study was to test the hypothesis that GH treatment has favorable effects on SM characteristics and motor performance in adults with PWS. DESIGN, SETTING, AND PARTICIPANTS: Fifteen obese PWS subjects (nine males and six females; age range, 19-35 y; body mass index, 37...

Lateral impact tests were performed using seven male post-mortem human subjects (PMHS) to characterize the force-deflection response of contacted body regions, including the lower abdomen. All tests were performed using a dual-sled, side-impact test facility. A segmented impactor was mounted on a sled that was pneumatically accelerated into a second, initially stationary sled on which a subject was seated facing perpendicular to the direction of impact. Positions of impactor segments were adjusted for each subject so that forces applied to different anatomic regions, including thorax, abdomen, greater trochanter, iliac wing, and thigh, could be independently measured on each PMHS...
