INTRODUCTION: Paediatric avulsion fractures of the pelvis and hip joint are rare injuries most commonly associated with a rapid muscle contraction of the respected apophysis, which is the weakest component of the growing skeleton. The chosen therapy option can be either conservative or surgical. METHODS: We present a cohort of 69 patients treated for an apophyseal avulsion fracture of the anterior superior / inferior iliac spine, the lesser and greater trochanters iliac crest and the ischial tubercle...

Off-loading or the Orthotic approach to wheelchair seating has been used successfully to provide seating that optimizes tissue protection at the ischial tuberosities (ITs), sacrum and greater trochanters. Recent publications indicate the significance of preventing tissue compression to reduce ulcer formation. Comparative Magnetic Resonance Imaging (MRI) of individuals seated on two cushion types provides direct evidence of tissue unloading resulting in the reduction in tissue compression. Measurement of tissue compression in MRI images provides the cumulative impact of compression and shear resulting in ultimate tissue thickness documented here...

NEW PATHOPHYSIOLOGICAL INSIGHTS: Based on improved knowledge of the vascular supply of the proximal femur, a safe surgical dislocation of the hip joint was established allowing direct insights to the pathomorphological malfunctioning of the joint. One insight was that slipped capital femoral epiphysis (SCFE) impingement leads to substantial damage of the chondrolabral rim area, even in the presence of minor slips. A further surgical development was the extended retinacular flap allowing for correction of the deformity with calculable risk for iatrogenic necrosis...

PURPOSE: Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures...

BACKGROUND: Dislocation is the second most common complication after total hip arthroplasty (THA). The effectiveness of soft tissue repair to reduce dislocation rate is still debated and thus a meta-analysis was conducted. METHODS: A systematic search in PubMed, Embase, and Cochrane databases was conducted for this meta-analysis. INCLUSION CRITERIA: clinical comparative trials on the use of soft tissue repair including rotators and capsule repair in primary THA...

The location of perianal abscesses and the course of the fistula follow certain patterns, especially in the relationship between external and internal openings. However, it is still not clear how the contents of the ischioanal fossa, especially the fibrous network of fat tissue, affect the route for such diseases. Ten male adult cadavers were selected for the study. Seven horizontal transverse section planes from 1cm above the pubic symphysis to the inferior border of the lesser trochanter of the femur were recorded after P45 sheet plastination...

BACKGROUND: Antegrade intramedullary (IM) nailing for skeletally immature femur fractures can damage the capital femoral epiphysis blood supply, leading to avascular necrosis (AVN) of the femoral head. Reported AVN rates are 2% for piriformis entry and 1.4% for trochanteric entry. None of previous reports described IM lengthening nails for limb lengthening procedures. We have used self-lengthening telescopic nails with a proximal Herzog bend and standard trochanteric entry for femoral lengthening in children...

An 85-year-old woman developed severe swelling and pain in the proximal thigh after internal fixation of an intertrochanteric fracture of the femur with a hip nail. In order to identify the causes and determine the effective treatment, angiography was performed. The results of the angiography revealed a pseudoaneurysm of a branch of deep femoral artery. Endovascular embolization was used to treat the pseudoaneurysm. After reviewing all possible causes, we found a mistake in insertion of a guide wire for hip nail...

AIMS: It may not be possible to undertake revision total hip arthroplasty (THA) in the presence of massive loss of acetabular bone stock using standard cementless hemispherical acetabular components and metal augments, as satisfactory stability cannot always be achieved. We aimed to study the outcome using a reconstruction cage and a porous metal augment in these patients. PATIENTS AND METHODS: A total of 22 acetabular revisions in 19 patients were performed using a combination of a reconstruction cage and porous metal augments...

BACKGROUND: Evidence on the diagnostic performance of palpatory methods and possible confounding factors is scarce. OBJECTIVES: To examine the sensitivity of palpatory methods for location of lumbopelvic landmarks and to assess its association with personal characteristics. METHODS: Eighty-three participants (41 men, 55.6 (16.5) years, 25.9 (4.8) kg/m2 [mean (SD)]) were enrolled in this single-blinded study. Fourteen body and softy-tissue landmarks were sequentially palpated from the spinous process of L4 to the ischial tuberosity...

Myasthenia gravis (MG) patients had low proximal hip BMD, which could be explained by reduced muscle strength, elevated bone resorption markers, vitamin D deficiency, and increased PTH levels in those with MG compared to controls. INTRODUCTION: Muscle strength is closely correlated with bone mineral density (BMD) and vitamin D status. Here, we evaluated muscle strength, BMD, and vitamin D status in a large sample of Chinese patients with MG. METHODS: In this cross-sectional survey, 86 patients with MG without glucocorticoid treatment and 86 healthy controls were included...

F Hefti, L Donnan, A H Krieg
AIMS: The severe form of coxa vara, the 'shepherd's crook deformity', is always a consequence of a locally extensive form of polyostotic fibrous dysplasia (or McCune-Albright syndrome). Treatment of this deformity is a challenge. The soft bone does not tolerate any implant that depends on the stability of the cortical bone (like plates or external fixators). Intramedullary nails are the most appropriate implants for stabilisation, but if they are inserted from the greater trochanter, they cannot correct the varus deformity enough...

BACKGROUND: Assessing femoral version in orthopedic surgery is important for preoperative planning of total hip arthroplasty, especially for recognizing excessive anteversion or retroversion. The present study addressed the following: (1) Is the position of the lesser trochanter correlated to the femoral neck axis? (2) If so, may femoral version be assessed by means of plain pelvic radiographs? METHODS: Three-dimensional computed tomography scans of 60 patients undergoing minimally invasive cement-free total hip arthroplasty were retrospectively analyzed, particularly with regard to the relation between the femoral neck axis and the lesser trochanter, the femoral version, and the size of the projected lesser trochanter in different rotational positions...

Wide-gauge posture of titanosauriform sauropods remains an enigmatic peculiarity among terrestrial vertebrates. Here, two-dimensional geometric morphometrics and thin plate splines analyses were used to quantitatively analyze shape differences among sauropodomorph humeri and femora to identify how these elements may differ according to body gauge. Results demonstrate that titanosauriforms generally possess proportionately gracile humeri in comparison to other sauropods, with relatively more medially oriented humeral heads and proximally located deltopectoral crests...

A new quill mite species of the family Syringophilidae (Acariformes: Prostigmata: Cheyletoidea) is described from Phimosus infuscatus (Lichtenstein) (Pelecaniformes: Threskiornithidae) in Argentina. Selenonycha insperata n. sp. differs from other species of the genus Selenonycha Kethley, 1970 by the presence of wing-like cuticular projections of coxal fields III-IV situated in front of trochanters (vs absence). An unexpected finding of this species on a bird of the family Threskiornithidae (Pelecaniformes) is discussed as an example of host shift...

BACKGROUND: Avulsion fractures of the pelvic apophyses typically occur in adolescent athletes due to a sudden strong muscle contraction while growth plates are still open. The main goals of this systematic review with meta-analysis were to summarize the evidence on clinical outcome and determine the rate of return to sports after conservative versus operative treatment of avulsion fractures of the pelvis. METHODS: A systematic search of the Ovid database was performed in December 2016 to identify all published articles reporting outcome and return to preinjury sport-level after conservative or operative treatment of avulsion fractures of the pelvis in adolescent patients...
