Objective: We present a case of a femoral stress fracture in a male Division I basketball player. Background: During post-season conditioning, the athlete (21 years, 200 cm, 102.3 kg) presented to the team physician with anterior mid-thigh pain. He reported intense pain that had progressively increased a month before he sought medical advice. The athlete indicated that the pain had spread from ...

Insufficiency fracture is of the stress fractures and is caused by repetitive stress on fragile bone. Insufficiency fractures of pubic rami are rare occurrences in association with total hip arthroplasty (THA). Postoperative stress fractures occur due to increase of patients activity following years of disability. The physician should consider the possibility of a pelvic insufficiency fracture ...

The tibial shaft is the most common location of stress fractures in athletes. Tibial stress fractures are divided into 2 groups, anterior and posterior, based on location. Posterior tibial cortex fractures are more common and respond well to conservative treatment. Fractures in the anterior cortex are less common, accounting for only 4.6% of stress fractures, and they often heal poorly because ...

A 22-year-old man presented to the Nuclear Medicine Clinic for evaluation of distal right tibial pain. The patient reported recently beginning a rigorous exercise program involving lower extremity impact temporally related to the onset and worsening of the pain. The physical examination was remarkable for significant tenderness to palpation of the distal one-third of his right tibia. The presum...

Tibial stress fractures are a common overuse injury among military recruits. The purpose of this study was to determine what, if any, long-term effects that tibial stress fractures have on military personnel with respect to physical activity level, completion of military training, recurrence of symptoms, and active duty service. Twenty-six military recruits included in a previous tibial stress ...

Stress fracture of the tibia secondary to sports-related activities is relatively common, but rarely occurs secondary to osteoarthritis of the knee. Such fractures usually involve the proximal tibia. We report a 61-year-old woman with osteoarthritis and severe varus deformity of the knee who had a stress fracture of the distal tibial shaft. The patient had declined total knee replacement for se...

It is known for long time that the size of a structure has an important effect on its fracture stress. This phenomenon is called size effect and it seems that it can be attributed to the influence of a damaged zone which develops around the fracture area. Investigations have been made on size effect in shear fracture on two species of wood : Maritime Pine and Norway Spruce. The experimental fra...

most of the earth's crust contains fluids, and fractures are common throughout the upper part. they exist at a wide range of scales from micro-fractures within grains to major faults and shear zones that traverse the crust. in this paper, the stress-dependent permeability in fractured rock masses have been investigated considering the effects of nonlinear normal deformation and shear dilation o...

behaviors of stress corrosion cracking (scc)in martensitic stainless steel(aisi 420) and low carbon austenitic stainless steel (aisi 316l) have been compared under different conditions of temperature, environment (mgcl2), and strain rate. the results show that decreasing strain rate has detrimental effect on mechanical properties of both steels, including their strength and ductility. fractogra...

Background: Presentation of proximal tibia stress fracture is not infrequent among elderly patients due to their poorbone stock. Optimal management of patients with severe gonarthrosis of the knee and concurrent tibial stress fracture isnot known yet. In this study we report the outcome of primary total knee arthroplasty (TKA) using stemmed componentsin elderly patients.Methods: Between 2009 an...
