Typical symptoms include pain and stiffness first thing in the morning. This uncommon form of inflammatory arthritis can target the spine, knees and hips. Inflammation in joints results in pain, prolonged stiffness (particularly first thing in the morning or after periods of rest) and swelling. The exact reason some people develop rheumatoid arthritis is unknown, although genetics and environmental factors like smoking may increase risk. Rheumatoid arthritis is an autoimmune disease that causes inflammation in joints such as the hands, wrists, elbows, shoulders, neck, hip, knees and feet.

Movement of the hip may also be restricted. Osteoarthritis in the hip can lead to pain in the groin or buttock area, particularly on walking. The exact cause of osteoarthritis is not known, but genetics, stress on the joint and local inflammation are thought to play a role. It is associated with degeneration of the joint cartilage and with changes in the bones underlying the joint. As well as the hip joints, it most often affects the hands, spine, knees and feet. Osteoarthritis is a common form of arthritis that tends to affect people as they age.

Referred pain (for example, from the spine).

Pain around the hip arises from structures separate from the hip joint itself, for example: There are also some hip problems predominantly seen in children, including: There are many condition that may cause hip problems, such as.

pain when trying to put weight through the leg on the affected side.

pain in the hip joint (usually felt in the groin area).

The hip joint is complicated so as to allow a wide range of motion while still supporting the weight of the body. The muscles of the legs overlay these ligaments. The ball is anchored firmly into the socket with tough connective tissue called ligaments. The joint is sealed inside a tough capsule made of membrane (synovial capsule), which contains lubricating fluid that aids smooth motion of the joint. Both the ball and socket are lined with cushioning tissue called cartilage. The thigh bone (femur) ends with a rounded projection or ball (femoral head), which fits into the socket (acetabulum) of the pelvic girdle. It is derived from Latin word trabs meaning beam or bar.The hip joint is the largest joint of the human body.

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.extends from the lateral margin of the greater trochanter to the inferior aspect below the fovea.secondary compressive/lateral compressive trabeculae.principal compressive/medial compressive trabeculae.Both tensile and compressive forces are present and correspond to the lines of forces. The proximal femur is an apt example to show the trabecular pattern based on Wolf’s law. 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. Wolff's law suggests that there are dynamic internal forces as well as static and dynamic external forces acting on the bone. 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. Trabecula is a supportive and connective tissue element which form in cancellous bone.
