Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb
Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement. [citation needed] This sense of the term "reduction" does not imply any sort of removal or quantitative decrease but rather implies a restoration: re ("back [to initial position]") + ducere ("lead"/"bring"), i.e., "bringing back to ...
Abduction is a motion that pulls a structure or part away from the midline of the body, carried out by one or more abductor muscles. In the case of fingers and toes, it is spreading the digits apart, away from the centerline of the hand or foot. [ 15 ]
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
An abductor wedge is designed to separate the legs of a patient. It is often used after hip surgery to prevent the new hip from "popping out".. It can also be used to support the legs of an individual with spinal cord injury or severe physical or neurological disabilities in abduction (legs apart position) while seated in a wheelchair.
The sole reliance on the hip joint to control the entire prosthetic limb makes fine-tuning foot placement difficult. Lowering the knee joint height was found to effectively increase the hip joint's lever arm, thereby increasing precision control of the hip joint to improve gait symmetry and increase running velocity by 26% on average.

The internal obturator muscle arises from the inner surface of the antero-lateral wall of the pelvis. [1] It surrounds the obturator foramen. [1] [2] It is attached to the inferior pubic ramus and ischium, and at the side to the inner surface of the hip bone below and behind the pelvic brim. [1]
Minimally invasive hip resurfacing (MIS) is a total or partial hip surgery that can be carried out through an incision of less than 10 cm (4 inches) without imparting great forces on the anatomy or compromising component positioning.
