Introduction. Osteonecrosis of the femoral head (ONFH) is an intractable disease that causes progressive femoral head collapse, severe pain, and gait disturbance. We report a case of avascular necrosis of the femoral head following an occult femoral neck stress fracture, which shows that early diagnosis and treatment are very important. Case report. A 55-year-old woman presented to our department with a chief complaint of low back pain that radiated into the left anterolateral thigh for 2 months Her left anterolateral thigh became progressively more painful over a period of about 2 weeks. No abnormal findings indicative of ONFH or an occult fracture of the femoral neck were detected by X-ray or computed tomography (CT), but an occult insufficiency fracture of the left femoral neck was identified on magnetic resonance imaging (MRI). The diagnosis of femoral neck stress fracture was delayed, resulting in femoral head necrosis. The fracture was treated with total hip arthroplasty and the resected femoral head was subjected to histopathology. Based on the histopathological findings, the final diagnosis of this case was ONFH with an occult fracture of the left femoral neck. Clinical symptoms were relieved postoperatively. Conclusion. In patients presenting with a suspected stress fracture of the femoral neck, early MRI examination is recommended to avoid femoral head necrosis due to a delayed diagnosis.

Background: Stress fracture of the femoral neck is rare in children. Its differential diagnosis includes muscle strain, synovitis, infection, dysplasia, etc. Since physicians rarely see this type of fracture in children, they often overlook it or misdiagnose it.  Case Report: A seven-year-old girl presented to our service with right groin pain following a fall on her right hip 15 days ago. Pelvic and knee radiographs of her right limb showed a fracture line with sclerosis at the femoral neck. Magnetic-resonance imaging (MRI) confirmed the diagnosis of a stress fracture of the femoral neck. We opted for conservative management and gave the patient analgesics and limited weight-bearing with the help of crutches for eight weeks. Three weeks after her first visit, the patient presented with severe limping and inability to bear weight on her right leg. Right hip radiographic imaging showed a varus displaced fracture of the femoral neck, which we managed surgically with an open reduction and internal fixation using plate and screws, followed by immobilization of the right hip with a hip spica cast. Six weeks following the surgery, the patient had no complaints, and the radiographic images showed an appropriate reduction and signs of union. The patient was allowed to start partial weight-bearing for a further six weeks before proceeding to full weight-bearing. Conclusion: Our case emphasizes the importance of considering femoral neck stress fracture in children, through a thorough clinical evaluation and imaging analysis, especially for those carrying classical risk factors. Failure to do so can complicate the disease course and may lead to a displaced fracture requiring more invasive and timely management.

Abstract Background Femoral neck stress fractures are rare and often recognized as overuse injuries that occur in young athletes or military personnel. A case following osteonecrosis of the femoral head is quite rare; even more uncommon is its occurrence in the bilateral hips. Magnetic resonance imaging has been established as the preferred tool for diagnosing nondisplaced femoral neck stress fracture due to overuse injury. Magnetic resonance imaging was also useful to detect the initial lesion even in this case, although the etiology was different between overuse injury and insufficiency fracture. Case presentation A 41-year-old Japanese woman diagnosed with bilateral early stage idiopathic osteonecrosis of the femoral head was observed non-weight-bearing as much as possible using a stick. However, her pain and difficulty in walking progressed. Bilateral femoral neck stress fractures were subsequently detected by magnetic resonance imaging. The fracture initially appeared as a spot of bone marrow edema at the medial site of the femoral neck, and then developed into a fracture line. The patient underwent internal fixation of both hips with sliding hip screws to stabilize the stress fractures. In addition, the preparatory reaming served as core decompression of the femoral heads, as well as being treatment for osteonecrosis. Her bone mineral density and 25-hydroxy vitamin D values were low for her age. We administered eldecalcitol and teriparatide acetate. Her symptoms mostly improved, and the fracture lines and necrotic lesions on magnetic resonance imaging reduced at 5 months after the surgery. Conclusions Bilateral femoral neck stress fractures are a very rare condition and are often missed. It is important to listen to the patient’s complaints and perform an appropriate examination. We encountered a case of bilateral femoral neck stress fracture that occurred in a patient with early stage osteonecrosis of the femoral head, and were able to observe progression of stress fracture since before fracture occurred. This is considered to be the first report to capture imaging changes before and after the onset.

<p> </p><p>Las fracturas por estrés afectan, con mayor frecuencia, a personas físicamente activas con hueso normal y son infrecuentes en los niños con placa de crecimiento abierta. Aun más infrecuentes son las fracturas por estrés del cuello femoral en la población pediátrica. Sin embargo, constituyen entidades muy importantes debido al riesgo de complicaciones graves, como la necrosis avascular. Se describe el caso de una niña de 7 años medicada con metilfenidato que sufrió una fractura por estrés del cuello del fémur atípica. La paciente consulta por dolor inguinal derecho sin limitaciones en las actividades cotidianas. La radiografía muestra una fractura por estrés del cuello del fémur, que se confirma con tomografía. Se instaura un tratamiento conservador, y la paciente está asintomática a las cuatro semanas. Este caso representa una alerta sobre esta infrecuente entidad en la que podrían presentarse errores diagnósticos. Investigaciones recientes también sugieren la posible participación de fármacos, como el metilfenidato, en la desmineralización ósea, que podría constituir un posible factor de riesgo de fractura.</p>
