BACKGROUND: Intraoperative femur fracture (IFF) is a well-known complication in primary uncemented total hip arthroplasty (THA). Variations in implant instrumentation design and operative technique may influence the risk of IFF. This study investigates IFF between a standard uncemented tapered-wedge femoral stem and its second-generation successor with the following design changes: size-specific medial curvature, proportional incremental stem growth, modest reduction in stem length, and distal lateral relief...

Hip fractures are a major cause of trauma related death, usually occurring in vulnerable elderly patients. There are an estimated 70,000 hip fractures in the UK per year with numbers set to rise. The estimated annual cost to the healthcare economy is in the region of £2 billion. A 17-year review examining litigation related to hip fractures was undertaken. Under a freedom of information request, data was obtained relating to all orthopaedic claims made to the NHS Litigation Authority (NHSLA) between 1995 and 2012...

Wilson's disease (WD) is a rare inherited disorder of copper metabolism. It chiefly has hepatic, neurological and ophthalmic manifestations. Although osteoporosis, rickets and early arthritis are common features of WD, they are under-recognized. Musculoskeletal manifestations very rarely lead to diagnosis of the disease. Here we present a case of a 12-year-old girl who presented with a 3-month-old pathological fracture of neck of femur. WD was diagnosed on investigating the cause of the pathological fracture, which was managed by performing a conventional McMurray's intertrochanteric osteotomy...

INTRODUCTION: The thrust plate hip prosthesis (TPP; Zimmer, Winterthur, Switzerland) is a hip prosthesis that is no longer in production. Few reports have focused on periprosthetic fractures following total hip arthroplasty (THA) with the use of a TPP. PRESENTATION OF CASE: We report a 57-year-old woman with a periprosthetic femoral fracture 13 years after THA with the use of a TPP. A plain radiograph showed a displaced subtrochanteric fracture of the right femur just below the distal tip of the lateral plate without implant loosening...

The intraoperatively rotational control of femoral shaft fractures treated with a closed intramedullary interlocking nailing is a challenging problem. A novel surgical technique that includes respective insertions of guidewires into the proximal and distal femur under the guidance of a 2-dimensional fluoroscopy-based navigation system and the measurements of the intersection angle subtended by the proximal and distal guidewires with the smartphone positional software has been designed to provide intraoperatively quantitative parameters of femoral rotation deformation...

Bone fracture pattern prediction is still a challenge and an active field of research. The main goal of this article is to present a combined methodology (experimental and numerical) for femur fracture onset analysis. Experimental work includes the characterization of the mechanical properties and fracture testing on a bone simulant. The numerical work focuses on the development of a model whose material properties are provided by the characterization tests. The fracture location and the early stages of the crack propagation are modelled using the extended finite element method and the model is validated by fracture tests developed in the experimental work...

OBJECTIVES: Parallel with body growth and development, bone structure in non-adults is reorganized to achieve the particular design observed in mature individuals. We traced the changes in three-dimensional trabecular microarchitectural design during the phases of locomotor maturation to clarify how human bone adapts to mechanical demands. MATERIALS AND METHODS: Micro-CT was performed on biomechanically-relevant subregions of the proximal femur (medial, intermediate and lateral neck regions, intertrochanteric region, metaphyseal region) from early postnatal period to late childhood...

INTRODUCTION: Femoral neck fractures are a common occurrence in lower limb amputees. Good post-operative results of hip hemiarthroplasty have been described in below-knee amputees. However, to our knowledge, very few such cases have been reported in above-knee amputees. CASE REPORT: We present a case of a 75-year-old male patient who underwent above-knee amputation of the right lower limb for severe crush injury right leg and a bipolar hemiarthroplasty for an ipsilateral fracture neck of femur sustained in the same road traffic accident...

INTRODUCTION: Tuberculosis is a major health problem worldwide. Extrapulmonary tuberculosis is often secondary to some primary foci in lungs. There are reports of tuberculous osteomyelitis involving maxilla, ulna, femur, and shoulder joint but none have reported pathological fracture in humeral diaphysis due to tuberculosis osteomyelitis without shoulder joint involvement. We report a case of pathological fracture of humerus diaphysis due to tuberculous osteomyelitis with normal articular space...

INTRODUCTION: The most common fractures during vaginal delivery occur in the clavicle, humerus, and femur. Cesarean section reduces the chances of a child having a birth injury. However, in some difficult extractions, long bone fractures may occur. Cesarean section further reduces the incidence of birth injuries, especially in a breech delivery. Maneuvers employed during cesarean section, energetic traction, improper uterine incisions, and contracted uterus may cause these injuries. In the medical literature, there are few articles highlighting the occurrence of long bone fractures during cesarean section...

BACKGROUND: Pathological fracture of the proximal femur is a main cause of cancer patients losing their ability to walk. Although both osteosynthetic devices (predominantly intramedullary nails) and prosthetic replacement have been widely performed for treatment, controversies exist regarding which procedure should be used for the various conditions. In order to decide the eligibility criteria of a planned randomized prospective study about the treatment of pathological fractures of the proximal femur, we assessed the factors affecting the selection of operative procedures using questionnaires sent to the members of the Bone and Soft Tissue Tumor Study Group (BSTTSG) of the Japan Clinical Oncology Group (JCOG)...

INTRODUCTION: The phases of fracture healing have been well characterized. However, the exact source and genetic profile of the skeletal progenitors that participate in bone repair is somewhat unclear. Sox9 expression in skeletal elements precedes bone and cartilage formation and a Sox9(+) cell type is retained in the adult periosteum. We hypothesized that Sox9(+) periosteal cells are multipotent skeletal progenitors normally participating in fracture repair. METHODS: To test this hypothesis we used tamoxifen (TM)-mediated lineage tracing of Sox9(+) cells in Sox9CreErt2:Td-Tomato mice...

Simultaneous bilateral intertrochanteric fractures are very rare, and only a few cases have been reported in the literature. They usually result from severe trauma. They are serious injuries with high morbidity and mortality rates. Successful management of these patients involves adequate resuscitation, treatment of associated injuries, early single-stage stable fixation, and good rehabilitation. We report the case of a 47-year-old male who presented with a simultaneous bilateral intertrochanteric fracture along with associated injuries following a car crash...
