Abstract
We reviewed radiographs of 1234 of the 1271 women who had a subtrochanteric or shaft fracture and identified 59 patients with atypical fractures. Data on medications and coexisting conditions were obtained from national registries. The relative and absolute risk of atypical fractures associated with...

Abstract
Valgus extension overload (VEO) is a constellation of symptoms and pathology commonly seen in the overhead athlete. Athletes in many sports may experience VEO and other common pathologies related to the high repetitive stresses generated by the overhead throwing motion. VEO is characterized by repro...

Abstract
Running has many beneficial effects, including cardiovascular and skeletal health. Poor training technique and a variety of risk factors may predispose runners to lower-limb overuse injuries affecting muscle, tendon, and bone. Injuries to the bone include stress reactions to full-fledged stress frac...

Abstract
Stress fracture represents an overuse injury of the bone resulting from excessive repetitive stress. Diagnosis in most cases is based on clinical evaluation. Plain radiographs may show characteristic changes 2 to 4 weeks from onset of symptoms. Increasingly, magnetic resonance imaging is recognized...

Abstract
Stress fracture is one of the common injuries of over-use syndrome among long-distance runners. This injury is more common among women, often relating to anorexia, menstrual disorder and the lowering of bone density. An early diagnosis is considered to be of importance for a rapid recovery which lea...

Abstract
Nonunions of fractures occur infrequently and can be multifactorial. Some predisposing factors include fracture instability, poor vascularity and inadequate fracture reduction. The role of metabolic bone disease and endocrine abnormalities in nonunions is often overlooked. This article reports a cas...

All four cases that fractured had a "dreaded black line" in the lesion, whereas only 1 of 12 patients had this fracture in femurs which remained intact (100% versus 8.3%, P = 0.003). All patients who fractured reported thigh discomfort over 1 month (range, 0.1-9.0 months; standard deviation, 4.0 mon...

Abstract
Evidence for preventive strategies to lessen running injuries is needed as these occur in 40%-50% of runners on an annual basis. Many factors influence running injuries, but strong evidence for prevention only exists for training modification primarily by reducing weekly mileage. Two anatomical fact...

Medial tibial stress syndrome (MTSS) is one of the most common lower leg injuries in athletes who run. Studies have reported MTSS to occur in 4% to 20% of this population. It can be defined as an overuse injury that creates pain over an area covering the distal to middle third of the posteriomedial...

A stress fracture of the calcaneus is the result of rhythmically recurring sub-threshold traumata and is typically seen in athletes. The diagnosis is difficult because stress fractures are easily missed in traditional radiographs. It is therefore recommended to perform magnetic resonance imaging. Tr...
