REVIEW
Jan Lesensky, Daniel E Prince
Successful cure is achieved in almost 70% of patients with primary bone sarcomas with currently available therapies. Some soft tissue sarcomas require wide bone resection in order to achieve appropriate margins for cure of disease, and patients undergoing these procedures need durable reconstruction. Biological reconstruction has been shown to provide patients with superior long-term results over other alternatives. Distraction osteogenesis is well studied in the correction of deformities as well as in addressing some congenital musculoskeletal pathologies...

Observational cross-sectional study. The current study aims to yield normative data: i.e., the physiological standard for 30 selected quantitative 3D parameters that accurately capture and describe a full-skeleton, upright-standing attitude. Specific and exclusive consideration was given to three distinct categories: postural, spine morphology and pelvic parameters. To capture such 3D parameters, the authors selected a non-ionising 3D opto-electronic stereo-photogrammetric approach. This required the identification and measurement of 27 body landmarks, each specifically tagged with a skin marker...

PURPOSE: The correlation between tibial tuberosity-trochlear groove distance (TT-TG) and joint size, taking into account several different parameters of knee joint size as well as lower limb dimensions, is evaluated in order to assess whether TT-TG indices should be used in instead of absolute TT-TG values. METHODS: This study comprised a retrospective analysis of knee CT scans, including 36 cases with patellofemoral instability (PFI) and 30 controls. Besides TT-TG, five measures of knee joint size were evaluated in axial CT slices: medio-lateral femur width, antero-posterior lateral condylar height, medio-lateral width of the tibia, width of the patella and the proximal-distal joint size (TT-TE)...

BACKGROUND: Hip dislocation is one of the most common postoperative complications after total hip arthroplasty (THA). Potential contributors include patient- and surgical-related factors. We performed a retrospective cohort study to identify risk factors for postoperative dislocation in patients receiving THA via the posterolateral approach. METHODS: We assessed 1326 consecutive primary THAs performed between 2010 and 2015. Patient information was documented, and plain radiographic films were used to evaluate cup positioning, hip offset, and hip length change...

PURPOSE: Good results of the cephalomedullary nails have been reported in proximal femoral fractures recently. Based on length of nails and shape of screws fixed in a femoral head for proximal fragment fixation, the proper nail length was in dispute. The purpose of this study was to evaluate the clinical and radiological results of a long cephalomedullary hip nail for the treatment of comminuted subtrochanteric femoral fractures. MATERIALS AND METHODS: Twenty-one consecutive patients with severe subtrochanteric femoral fractures who had undergone intramedullary fixation using long-PFNA II between March 2010 and March 2013 were followed-up for over 12 months...

Sam Khamis, Eli Carmeli
Controversy still exists as to the clinical significance of leg length discrepancy (LLD) in spite of the fact that further evidence has been emerging regarding the relationship between several clinical conditions and LLD. The objectives of our study were to review the available research with regard to LLD as a cause of clinically significant gait deviations, to determine if there is a relationship between the magnitude of LLD and the presence of gait deviations and to identify the most common gait deviations associated with LLD...

Developmental dislocation of the hip(DDH) is one of the most serious hip diseases. Patients with unilateral DDH are prone to secondary osteoarthritis, low back pain, gait disturbance and compensatory scoliosis because of the leg length discrepancy. Total hip arthroplasty(THA) is the highly effective treatment for patients with hip pain or dysfunction caused by unilateral DDH, thus decrease the demand for hip-preserving surgeries such as capsular arthroplasty which may postpone or avoid hip replacement. However, the failure rate of THA for young patients is high and the majority of young patients may require one or more revision arthroplasties throughout their lifetime...

STUDY QUESTION: Are body size across the life course and adult height associated with endometriosis? SUMMARY ANSWER: Endometriosis is associated with lean body size during childhood, adolescence and adulthood; tall total adult height; and tall sitting height. WHAT IS KNOWN ALREADY: The literature suggests that both adult body size and height are associated with endometriosis risk, but few studies have investigated the role of body size across the life course...

BACKGROUND: Accurate cup positioning is one of the most challenging aspects of total hip arthroplasty (THA). Undetected movement of the patient during THA surgery can lead to inaccuracies in cup anteversion and inclination, increasing the potential for dislocation and revision surgery. Investigations into the magnitude of patient motion during THA are not well represented in the literature. METHODS: We analyzed intraoperative pelvic motion using a novel navigation device used to assist surgeons with cup position, leg length, and offset during THA...

The posterior cruciate ligament (PCL) plays an important role in the structural stability and sensory feedback at the knee. Altered structural and proprioceptive function at the PCL-deficient knee may affect the joint motions and the end-point control during functional activities. The current study identified the effects of unilateral PCL deficiency (PCLD) on the end-point control and joint kinematics of the lower limbs during obstacle-crossing. Eighteen patients with unilateral PCLD and eighteen healthy controls were each asked to walk and cross obstacles of heights of 10%, 20% and 30% of their leg lengths, with the affected and the unaffected limb leading, while their kinematic data were measured...

PURPOSE: A dry powder inhaler formulation of the inhaled corticosteroid fluticasone furoate (FF) is being evaluated for use in children. An important potential risk associated with the use of inhaled corticosteroids in children is growth suppression. Therefore, the aim of this study was to assess the short-term lower leg growth in children with asthma treated for 2 weeks with inhaled FF versus placebo from the ELLIPTA inhaler. METHODS: Prepubertal children with persistent asthma (n = 60; aged 5 to <12 years) were recruited into a randomized, double-blind, placebo-controlled, 2-way crossover, noninferiority study...
