femoral neck stress fracture

Gun-Woo Lee, Kyung-Soon Park, Taek-Rim Yoon, Eshnazarov Kamolhuja Eshnazarovich
A femoral neck stress fracture in child is rare, particularly in bilateral case. It is easy to miss initially or may be misdiagnosed. The authors experienced a case of bilateral femoral neck stress fracture in a 10-year-old boy with bilateral hip. The patient was successfully healed by conservative treatment. We report this rare case with a review of the literature. A femoral neck stress fracture should be included in the differential diagnosis in children who present with sustained hip or groin pain.

BACKGROUND: Hip fractures are mainly caused by accidental falls and trips, which magnify forces in well-defined areas of the proximal femur. Unfortunately, the same areas are at risk of rapid bone loss with ageing, since they are relatively stress-shielded during walking and sitting. Focal osteoporosis in those areas may contribute to fracture, and targeted 3D measurements might enhance hip fracture prediction. In the FEMCO case-control clinical study, Cortical Bone Mapping (CBM) was applied to clinical computed tomography (CT) scans to define 3D cortical and trabecular bone defects in patients with acute hip fracture compared to controls...

Chronic obstructive pulmonary disease(COPD)is a chronic inflammatory disease associated with an increase of fracture risk. Bone strength is determined by bone mass and quality.Bone quality is thought to encompass the structural and material properties of bone. Bone collagen crosslinking plays important roles in bone strength. The quantitative and qualitative deterioration of lysyl oxidase control and non enzymatic cross-links(advanced glycation end products, AGEs, pentosidine)of collagen in patients with osteoporotic femoral neck fracture and diabetes, and COPD might be affected by increased oxidative stress and glycation...

UNLABELLED: Femoral-neck stress fractures are relatively rare and may present as sports-related injuries. The presentation is variable, and prompt diagnosis facilitates the earliest return to pre-morbid functional activity levels. Delayed detection may precipitate femoral non-union or avascular necrosis, resulting in long-term functional deficit. AIMS: We describe the clinical, diagnostic and therapeutic approach of a femoral-neck stress fracture that occurred in a 28-year-old female recreational runner...

BACKGROUND: Serum uric acid (SUA) accounts for about 50% of extracellular antioxidant activity, suggesting that hyperuricemia may have a protective role in diseases characterized by high levels of oxidative stress, such as osteoporosis. We aimed to meta-analyse data regarding bone mineral density (BMD), osteoporosis and fractures in people with higher SUA vs. lower SUA concentrations. MATERIALS AND METHODS: Two investigators conducted a literature search using PubMed and Scopus, without language restrictions...

Over 90% of hip fractures are caused by falls. Due to a fall-induced impact on the greater trochanter, the posterior part of the thin superolateral cortex of the femoral neck is known to experience the highest stress, making it a fracture-prone region. Cortical geometry of the proximal femur, in turn, reflects a mechanically appropriate form with respect to habitual exercise loading. In this finite element (FE) modeling study, we investigated whether specific exercise loading history is associated with femoral neck structural strength and estimated fall-induced stresses along the femoral neck...

BACKGROUND: Femoral neck fractures in young individuals are typically vertical shear fractures. These injuries are difficult to stabilize due to a significant varus displacement force across the hip with weight bearing. The purpose of this study was to evaluate the biomechanical stability offered by the addition of an augmented wire to conventional inverted triangle triple screw fixation for stabilizing vertical shear femoral neck fracture. METHODS: Sixteen medium 4th-generation synthetic composite femurs (Sawbones Pacific Research Laboratories, Vashon, WA) were divided into two groups...

Stress insufficiency fracture is usually diagnosed clinically and on the basis of routine X-ray imaging findings. However, the absence of any known predisposing factors and negative or occult radiographic findings pose diagnostic challenges. We report the case of an elderly male patient who presented with a chief complaint of trivial left hip pain and with equivocal radiographic findings. Triphasic (99m)Tc-methylene diphosphonate bone scan and single-photon emission computed tomography/computed tomography helped in arriving at the diagnosis of stress insufficiency fracture involving femoral neck...

Treatment of periprosthetic femur fractures after total hip arthroplasty remains a major challenge in orthopedic surgery. Recently, a novel surgical technique using intraprosthetic screw fixation has been suggested. The purpose of this study was to evaluate the influence of drilling the femoral hip stem on integrity and strength of the implant. The hypothesis was that intraprosthetic drilling and screw fixation would not cause the load limit of the prosthesis to be exceeded and that deformation would remain within the elastic limit...

A systematic review, following strict inclusion criteria, identified 32/48 low and 16/48 high-performance runners with stress fractures of the femoral neck. Surgical treatment was performed in 33/48 cases and was significantly higher (p = 0.009) in high-performance runners. Among the 28/48 runners who resumed running, there were significantly more lower-performance runners (23/32) than higher-performing runners (5/16) (p = 0.012) and significantly more non-displaced (22/30) than displaced fractures (6/18) (p = 0...

BACKGROUND: Limited research is available regarding return-to-running (RTR) time after femoral neck stress fractures. While studies have shown the prognostic value of image-based grading scales for stress fractures at other sites, few have included femoral neck stress fractures. PURPOSE: To determine if the grade of femoral neck stress fractures based on magnetic resonance imaging (MRI) characteristics correlates with RTR time. STUDY DESIGN: Cohort study; Level of evidence, 3...

In Fanconi syndrome, hypophosphatemic osteomalacia is caused by proximal renal tubule dysfunction which leads to impaired reabsorption of amino acids, glucose, urate, and phosphate. We present a rare case of a 43-year-old Korean male who was found to have insufficiency stress fracture of the femoral neck secondary to osteomalacia due to Fanconi syndrome. He had been receiving low-dose adefovir dipivoxil (ADV, 10 mg/day) for the treatment of chronic hepatitis B virus infection for 7 years and he subsequently developed severe hypophosphatemia and proximal renal tubule dysfunction...

Image-based finite element analysis (FEA) has been considered an effective computational tool to predict hip fracture risk. The patient specific FEA gives an insight into the inclusive effect of three-dimensional (3D) complex bone geometry, and the distribution of inhomogeneous isotropic material properties in conjunction with loading conditions. The neck region of a femur is primarily the weakest in which fracture is likely to happen, when someone falls. A sideways fall results in the development of greater tensile and compressive stresses, respectively, in the inferior and superior aspects of the femoral neck, whereas the state of stress is reversed in usual gait or stance configuration...

Introduction Acute gastrointestinal stress ulceration is a common and serious complication of trauma. Prophylactic proton pump inhibitors (PPIs) or histamine receptor antagonists have been used in poly-trauma, burns and head and spinal injuries, as well as on intensive care units, for the prevention of acute gastric stress ulcers. Methods We prospectively studied the use of prophylactic PPIs in with femoral neck fracture patients, gathering data on all acute gastric ulcer complications, including coffee-ground vomiting, malena and haematemesis...

Femoral neck stress fractures in young healthy individuals are rare and occur in those who take part in physical training with repetitive loading and those with osteoporosis. Bone density is related to sex hormone status, which is artificially manipulated during gender reassignment. Conflicting evidence currently exists on the effect of cross sex hormone treatment on bone density, with no literature suggesting a link between hormone treatment in gender reassignment and stress fractures. Our aim is to highlight the potential risk of stress fractures amongst transsexual patients receiving cross sex hormones as part of gender reassignment...
