Transient Osteoporosis of the Hip

Stress osteopathy of the femoral head: 10 military recruits followed for 5-11 years

“…The diffuse decrease in the signals in the bone marrow in the T1-weighted images is a nonspecific finding, but it corresponds well to the signals that are seen in association with stress fractures (Lee and Yao 1988), early avascular necrosis of the femoral head (Turner et al 1989) and transient osteoporosis (Takatori et al 1991). Hofman et al (1993) ascribed transient osteoporosis to the bone marrow edema syndrome and showed a correlation of the histologic bone marrow edema to the MRI findings.…”

“…Stress osteopathy, using bone scan and MRI, clinically resembles transient osteoporosis of the hip (Bloem 1988, Takatori et al 1991, Urbanski et al 1991.…”

Síndrome de edema de la médula ósea de cadera

“…La RM permite un diagnóstico precoz, incluso a las 48 h del inicio del dolor 50 , detecta casos sin osteopenia radiográfica y excluye otros diagnósti-cos. El patrón de edema de la médula ósea consiste en disminución uniforme y difusa de la señal en T1 y aumento de la señal en T2 y STIR en la cabeza y cuello que se extiende a la región intertrocantérica (Figura 2) 6,7,29,35,[50][51][52][53][54] . Es común encontrar derrame articular.…”

“…En el caso de la cadera, el diagnóstico diferencial incluye necrosis avascular (NAV), fractura por estrés del cuello femoral, neoplasias, infecciones osteoarticulares (osteomielitis, artritis, tuberculosis), artritis inflamatorias, condromatosis sinovial o sinovitis villonodular [4][5][6][7][8][9] , con las posibles implicaciones que esto trae en cuanto a procedimientos diagnósticos y terapéuticos.…”

Displaced subcapital fracture of the hip in transient osteoporosis of pregnancy

“…Pain typically comes on gradually during the last trimester of pregnancy, and is localised to the groin, greater trochanter and anterior part of the thigh. Active and passive movements of the hip are usually full, and laboratory tests are normal, apart from a raised sedimentation rate and urinary hydroxyproline level [10]. Bone scans show increased uptake in the proximal femur shortly after the onset of symptoms [7].…”
