It is derived from Latin word trabs meaning beam or bar. stage IV: medial trabeculae are in alignment with those of pelvis.stage III: medial trabeculae are out of alignment with those of pelvis.stage II: medial trabeculae of head form an angle of approximately 160° with femoral neck.stage I: medial trabeculae form an angle greater than 180°.Importance of trabecular patternĪs per the Garden classification of subcapital femoral fractures, the displacement is graded as per the position of the medial compressive trabecular 4. extends from the calcar and lesser trochanter to the greater trochanterĪ central area bounded by the three trabecular patterns is referred to as the Ward triangle 4.Secondary compressive/lateral compressive trabeculae extends from the medial cortex of the head into the femoral neck.it is vertically oriented and has a triangular configuration.Principal compressive /medial compressive trabeculae the arc traverses through the superior cortex of the neck and the femoral head.At 3-month follow-up, (B) the radiograph showed decreased bone density of the femoral head with. extends from the lateral margin of the greater trochanter to the inferior aspect below the fovea (A) AP radiograph of the right hip on presentation was normal.secondary compressive/lateral compressive trabeculae.principal compressive/medial compressive trabeculae.Both tensile and compressive forces are present and correspond to the lines of forces. Ages are approximate (generally, at most +/- 1-2 months, but mostly within + / 15 days unless stated otherwise). The proximal femur is an apt example to show the trabecular pattern based on Wolf’s law. This is a repository of radiograph examples (X-rays) of the pediatric (children) skeleton by age, from birth to 15 years. If the loading on a particular bone increases, then the bone will remodel itself over time to become stronger and resist the loading in that particular bone segment and for that particular force of loading. Wolff's Law implies a reaction of a living bone to the mechanical forces on a bone segment 3. These static forces are imposed by gravity and the dynamic forces by weight bearing.

Ultrasound allows evaluation of joint effusion, synovial thickening and neovascularity, the bone/cartilage contour, and the femoral head-neck alignment. Wolff's law suggests that there are dynamic internal forces as well as static and dynamic external forces acting on the bone. During childhood, ultrasound is a quick method to assess hip pain and quite often may be used to avoid use of irradiating techniques, such as radiography or CT. To understand the progress of trabecular pattern, it is imperative that we understand the concept put forth by Julius Wolff, known as the Wolff’s Law 3.

The trabecular pattern of growth follows the course of stress lines along the bone and maximum trabeculae develop along the lines of maximum stress. Trabeculae develop in a normal bone and also in a healing bone. the unaffected leg is bent to stabilize the patient position i.e.Trabecula is a supportive and connective tissue element which form in cancellous bone.Spinal X-rays help healthcare providers figure out why you have neck pain or back pain. On an X-ray, your bones (in this case, your vertebrae) show up as white and your soft tissues (like muscle and fat) show up as shades of gray. the patient is rolled at least 45° onto the side of interest with a hip flexion of 90° A spine X-ray is an imaging test that uses electromagnetic waves to take pictures of the bones in your neck and back.The World Health Organization (WHO) operationally defines osteoporosis as a bone mineral density T-score less than -2.5 SD (more than 2.5 standard deviations under the young-adult mean), which is measured by dual-energy x-ray absorptiometry (DEXA), in postmenopausal women and men at least 50. As this particular projection involves rolling the patient onto the side of interest, it is hence not suitable for trauma situations.įor trauma imaging of the hip, see: horizontal beam lateral. Osteoporosis is a metabolic bone disease characterized by decreased bone mass and skeletal fragility. suspected osteoarthritis of the hip) in an orthogonal plane to the AP projection. This view assesses the hip joint for any potential fractures, dislocations, bone lesions or degenerative diseases (i.e.
