To the Editor: I have read the article “Progression of a fracture site impaction as a prognostic indicator of impacted femoral neck fracture treated with multiple pinning” by Yoon et al. in the current issue of your esteemed journal and congratulate the authors. Yet, I would like to elaborate on a few important relevant concepts in the same regard. Th e authors have not considered the other vec...

The study describes the acoustic emission (AE) activity during human femur tissue fracture. The specimens were fractured in a bending-torsion loading pattern with concurrent monitoring by two AE sensors. The number of recorded signals correlates well with the applied load providing the onset of micro-fracture at approximately one sixth of the maximum load. Furthermore, waveform frequency conten...

This prospective study was aimed to evaluate the incidence of osteonecrosis in Thai patients with fracture neck of femur Forty-three patients who had sustained fracture were enrolled in the present study. The overall incidence of osteonecrosis was 72.1%. Incidence of osteonecrosis was 53.3% among patients who underwent surgery within 1 week after injury and 82.1% among those who underwent surge...

Ten cases of fractured neck of femur studied at necropsy were found to have established contralateral intracerebral lesions. These were mainly infarcts, and it suggested that the presence of hemiparesis predisposes to a fall on to the affected side and that the body weight acts through the hip joint in such a way as to fracture the femoral neck. This may happen irrespective of the magnitude of ...

Cathepsin K inhibitors have been demonstrated to restore bone mass in both animal model and postmenopausal osteoporotic patients. In the present study, we performed to investigate the pharmacological effect of icariin in the healing potential and biomechanical properties of femoral neck in a mice fractured model. The results showed that the mRNA and protein expression of cathepsin K was markedl...

Studying stress and strain trends in the femur and recognizing femur failure mechanism is very important for preventing hip fracture in the elderly. The aim of this study was to identify high stress and strain regions in the femur during normal walking and falling to find the mechanical behavior and failure mechanism of the femur. We developed a finite element model of the femur from the subjec...

OBJECTIVE To determine whether there is a difference on the bone architecture in patients with femoral neck fracture compared to patients with intertrochanteric fractures and assess the importance of aging on bone microarchitecture in patients with proximal femoral fracture. METHODS Biopsy of the iliac crest was made in seventeen patients between 55 and 90 years old who were admitted to the e...

The authors performed a cadaveric study to evaluate the efficacy of multiple fluoroscopic projections in detecting intra-articular penetration of the screws during femoral neck fracture fixation and also to determine the most suitable radiographic projection. Models of intra-articular penetration in 8 normal proximal femur specimens were created by placing the pins in different quadrants of the...

Hyperparathyroidism is a condition which can be primary, secondary or tertiary and is characterized by increased calcium levels, low phosphate levels, and elevated parathyroid hormone (PTH) levels. Primary hyperthyroidism can cause severe bone resorption leading to bone pains and pathological fracture. We present the case of a patient with severe primary hyperparathyroidism with an atraumatic f...

Unilateral stress fractures of the femoral neck are very uncommon and bilateral involvement is even rarer. They commonly occur in athletes, military recruits, older persons, or individuals with underlying metabolic disorders and very seldom in normal individuals. We present a rare case of simultaneous bilateral fracture neck of femur in a 25-year-old man who came with complaints of pain in bila...
