Garden stage I: undisplaced incomplete, including valgus impacted fractures. It is simple and predicts the development of AVN 1 ,2 . Grading Stress Fractures w/ MRI – Various Grading Scales/Projections of disability !Friedrickson,!1997! Stress fractures can be further broken down based upon whether they occur as the result of excessive and repetitive strain placed on structurally normal bone (fatigue reaction) or normal stress applied to structurally abnormal bone (insufficiency reaction). AU - Ramey, Lindsay N. AU - McInnis, Kelly C. AU - Palmer, William E. PY - 2016/8/1. 1-5 Locations where femoral and/or “hip” stress fractures occur include: femoral shaft, femoral diaphysis, femoral neck, pubic rami, and sacral ala. medial group of femoral neck trabeculae may demonstrate a greenstick fracture; Garden stage II: undisplaced complete The stress fracture, first described by Breithaupt in 1855, [] is a common overuse injury seen in athletes and military recruits. The commonest causative sports are marathon and long-distance running.

Femoral neck stress fractures are unusual but not rare athletic injuries. Femoral neck stress fracture is a rare occurrence but can arise in athletes and people who exercise, due to repeated stress on the lower extremities. A classification system for grading stress fractures with scintigraphy and/or MR imaging has been proposed . A stress fracture is a small crack in a bone. Femoral Neck Stress Fractures: MRI Risk Factors for Progression. T1 - Femoral Neck Stress Fracture. [3]Stress fractures of the femur can occur at the neck (highest incidence), the femurshaft and the condyle.

modality of choice for stress fractures when radiographs are normal; Bone scan has good sensitivity but very poor specificity (therefore MRI is better) Treatment: Nonoperative non-weight bearing, crutches and activity restriction. This may be useful in cases where the pre-contrast MR images show a callus, fracture, or muscle edema, and in situations where there is a concomitant malignancy or infection [ 69 ]. Most stress fractures are caused by overuse and repetitive activity, and are common in runners and athletes. Indications for obtaining an MR study include a suspicion of a femoral neck stress fracture in an athlete. indications compression side stress fractures with fatigue line <50% femoral neck … Dobrindt,!2012!!Arndt,2003!!!!! The Garden classification of subcapital femoral neck fractures is the most widely used. These are located on the outer side of the femoral neck. BACKGROUND: Femoral neck stress fractures are overuse injuries with devastating consequences if not diagnosed and treated appropriately. The aim of … Treatment of femoral stress fractures is … Author information: (1)Department of Orthopedics, Naval Medical Center San Diego, San Diego, California. One study by Orava14 reported a 3.5% incidence of femoral shaft involvement among 200 stress fractures, while Tension fracture. The most common reported symptom is exercise-related groin pain. Keywords: femoral neck stress fracture, femoral neck stress fracture classification, femoral neck stress injury, stress fracture, stress injury Lower extremity bone stress injuries (BSIs) are common in young, suboptimally conditioned individuals who abruptly engage in activities that involve running [ 1 ]. Steele CE(1), Cochran G(1), Renninger C(1), Deafenbaugh B(1), Kuhn KM(1). OF A FEMORAL STRESS FRACTURE.

tion of the femoral neck in any fluid-sensitive MRI sequence. STUDY DESIGN: Cohort study; Level of evidence, 3. 59. There are only few clinical signs, but they don’t allow to differentiate a stress fracture from another injury. mortality ~25-30% at one year (higher than vertebral compression fractures) predictors of mortality. However, dynamic enhancement has been reported in patients with higher grade stress reactions and stress fractures caused by increased tissue perfusion. Instead of resulting from a single severe impact, stress fractures are the result of accumulated trauma from repeated submaximal loading, such as running or jumping. Table 1: Radiologic Grading System for Stress Fractures* Treatment Overview. Femoral stress fractures have proven to be elusive with the average delay in diagnosis around 14 weeks. On MRI, cases without macro- All cases in which radiography was used as the single imaging modality to diagnose an FNSI had a complete macroscopic fracture spanning the entire width of the femoral neck obviating further evaluation with MRI; these cases were considered high-grade FNSI. [1]Femoral shaft stress fractures are not easy to diagnose.
