We present three patients with signs and symptoms of meralgia paresthetica (MP) after long-distance walking and cycling. No other possible causes of MP, such as trauma or exogenous compression, were present. A neuropathy of the lateral femoral cutaneous nerve was confirmed in all patients with somatosensory evoked potentials. We propose that conduction block due to local ischemia during repetit...

After a review of previous classifications the authors suggest that cases of congenital longitudinal deficiency of the femur fall into one of two groups, each with specific features. The treatment alternatives and their indications are discussed in detail and a treatment plan suggested.

The development of pseudotumors is not uncommon with metal-on-metal total hip arthroplasty. Pseudotumors that dissect into the retroperitoneal space can cause symptoms of nerve compression. We describe a case of a 53-year-old male with a metal-on-metal total hip arthroplasty who developed mild symptoms of a femoral nerve neuropathy 6 years postoperatively. Revision arthroplasty to a ceramic-on-...

Although the existence of atypical femoral fractures is well established and bisphosphonate therapy is thought to be a major risk factor, the underlying mechanisms are poorly understood. Epidemiological data show that atypical femoral fractures account for only a small proportion of diaphyseal subtrochanteric femoral fractures, being about 100 times less common than proximal femoral fractures. ...
