Femoral neck stress fracture occured commonly in athlete and military recruit populations, some of them are bilateral. Bilateral femoral neck stress fracture that associated with other occupation is very uncommon. We report a bilateral femoral neck stress fracture case that presented with unilateral symptoms in a male shipman laborer. The patient was successfully treated conservatively. Stress fracture sometimes occur associated with an unexpected specific occupation. Consideration of bilateral involvement is highly important in managing stress fracture...

Acetabular rim fractures, or os acetabuli, are hypothesized to occur as a result of an unfused ossification center or a stress fracture from repetitive impingement of an abnormally shaped femoral neck against the acetabular rim. When treated surgically, these fragments are typically excised as part of the correction for femoroacetabular impingement. However, in some patients, removal of these fragments can create symptoms of gross instability or microinstability of the hip. In these cases, internal fixation of the fragment is necessary...

Bone fracture healing is a complex process which at best results in full recovery of function and structure of injured bone tissue, but all the mechanisms involved in this process, and their mutual interaction, are not fully understood. Despite advancement of surgical procedures, this type of fractures is still a major public health concern. In the last few decades, a lot of attention is focused on the oxygen-free radicals and inflammatory response markers as important factors of skeletal injury. Thus, the aim of the present study was to follow the changes in redox balance and inflammatory response in elderly patients with femoral fractures during the earliest stages of fracture healing, by measuring the values of the observed markers immediately after fracture, as well as the first, third, and seventh postoperative day...

The Military Health System Management Analysis and Reporting Tool was queried to identify all active duty US military service members who underwent operative fixation of femoral neck stress fractures from 2011 to 2012. A total of 13 patients with 17 femoral neck stress fractures met the inclusion criteria. Average patient age was 23.8±5.1 years, and 62% were women. At a mean 26-month follow-up, approximately one-half (46%) of the young military recruits were able to return to their preoperative activity level...

BACKGROUND: According to currently available data, the clinical short-term results of the MoPyC radial head prosthesis (Bioprofile, Tornier, Montbonnot-Saint-Martin, France) seem favorable. However, we have encountered several implant-specific complications in recent years. Hence, this case series reports rare complications after radial head arthroplasty with the MoPyC prosthesis to make surgeons aware of their existence and to provide information about the underlying cause and possible salvage strategies...

BACKGROUND: Patients with proximal femoral neck fracture have a high short-term mortality, a high risk of postoperative complications, and impaired quality of life. One of the challenges related to the prehospital treatment of these patients is to administer systemic opioids fast and properly. Effective analgesic prehospital treatment ought be initiated rapidly in order to alleviate the stress that follows acute pain, to facilitate transportation, and to improve quality of care. The objectives of this study were to explore the prevalence of prehospital administration of intravenous fentanyl to patients with proximal femoral neck fracture in the ambulances and to assess risk factors for analgesic non-treatment...

BACKGROUND: Increased modularity in total hip arthroplasty (THA) through extra junction between the neck and the femoral stem is gaining popularity among orthopaedic community. However, the advantage of the additional junction is shadowed by an increased risk of mechanical failure. The aim of this study was to describe the exact mechanism of fracture of the modular femoral neck in an uncemented stem. METHODS: Clinical, metallurgical, and mechanical analysis including finite-element modelling and elemental-sensitive tissue analysis with the micro-PIXE method was performed on two patients treated with fully modular primary THA made from Titanium alloy of the same oval taper-cone design...

OBJECTIVES: Timely diagnosis of femoral neck stress fractures is important to prevent fracture completion and displacement. We hypothesize that an abbreviated magnetic resonance imaging (MRI) hip examination can diagnose femoral neck stress fractures and that femoral neck stress fractures are common in U.S. military recruits. METHODS: We retrospectively reviewed abbreviated hip MRI examinations performed on active duty patients from November 1, 2013, to August 5, 2014...

Bilateral stress fracture of femoral neck in healthy young patients is an extremely rare entity, whose diagnostic and treatment represent a major challenge. Patients with history of hip pain, even non-athletes or military recruits, should be analyzed to achieve an early diagnosis and prevent possible complications from the surgical treatment. This report describes a 43-year-old male patient, non-athlete, without previous diseases, who developed bilateral stress fracture of femoral neck without displacement...

The authors report on an 81-year-old woman with a pathologic hangman's fracture secondary to a complex arteriovenous fistula (AVF). The patient presented with severe, unremitting neck pain and was found to have fractures bilaterally through the pars interarticularis of C-2 with significant anterior subluxation of C-2 over C-3 along with widening of the left transverse foramen. Due to an abnormally appearing left vertebral artery (VA) on CT angiography, the patient underwent conventional angiography, which revealed a complex AVF stemming from the left VA at the level of C-2 with dilated posterior cervical veins and a large venous varix...

Osteoporosis is a common condition with significant health care costs. First-line therapy is with bisphosphonates, which have proven anti-fracture efficacy. Around 10 years after the introduction of bisphosphonates reports began to be published of atypical femoral fractures (AFFs) that may be associated with this therapy. These fractures are associated with significant morbidity although lower mortality than the more common osteoporotic neck-of-femur fractures. A case definition has been described to allow identification of this class of fracture...

Athletic overuse injuries are becoming an increasingly common entity in the active pediatric population. The prevalence of these injuries may be attributed to the combination of an underdeveloped musculoskeletal system, increased participation in competitive sport at a younger age, and increased duration and intensity of training. Many of these injuries may go unreported and/or undiagnosed, as they do not all result in time lost from sports, and are not always appreciated on imaging. Left unrecognized, untreated, or poorly managed, overuse injuries can have long-term health consequences for young athletes...

Femoral neck stress fractures have been described in military recruits and athletes. Early recognition and aggressive treatment are important, as femoral neck stress fractures have a high potential for complications and even uncomplicated fractures require an extensive course of rehabilitation. Tension-side (superolateral) stress fractures of the femoral neck are at high risk for complications such as displacement, non-union and avascular necrosis, and need to be treated surgically, while compression-side (inferomedial) fractures can be treated conservatively...

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...

Stress fractures may occur at various sites in the femur including the head, neck, shaft, supracondylar and condylar regions. To the best of our knowledge, stress fracture occurring in the trochanteric region has not been previously reported. We report here a case of trochanteric stress fracture in a 53-year-old female window cleaner treated with hip nailing without adverse consequences. Careful consideration of this entity is needed when evaluating patients who have repetitive jumping up and down.
