Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
Risk factors in women include increased hip adduction and knee internal rotation. [2] [3] Risk factors seen in men are increased hip internal rotation and knee adduction. [2] ITB syndrome is most associated with long-distance running, cycling, weight-lifting, and with military training. [4] [5]
The lower leg and ankle is grasped maintaining 20 degrees of internal tibial rotation. The knee is allowed to sag into complete extension. The opposite hand grasps the lateral portion of the leg at the level of the superior tibiofibular joint, increasing the force of internal rotation.
Athletic taping is the process of applying tape directly to the skin or over pre-wrap in order to maintain a stable position of bones and muscles during athletic activity. It is a procedure that uses athletic tape ( pressure-sensitive tape similar to surgical tape or elastic therapeutic tape ), attached to the skin , to physically hold muscles ...
Commonly used exercises include isometric quadricep sets, side lying clamshells, leg dips with internal tibial rotation, etc. The idea is that because the medial side is most often stretched by the more common lateral dislocation, medial strengthening will add more stabilizing support.
The muscles of internal rotation include: of arm/humerus at shoulder. Anterior part of the deltoid muscle [1] Subscapularis [1] Teres major [1] Latissimus dorsi [1] Pectoralis major [1] of thigh/femur at hip [2] Tensor fasciae latae; Gluteus generalis; Anterior fibers of Gluteus meralis; Adductor longus and Adductor brevis; of leg at knee [3 ...
The thigh is then stabilized and the foot externally rotated. The examiner watches for the tibial tubercle of the affected knee to rotate as the foot rotates, comparing it to the contralateral knee. A positive test will show rotation of greater than 10-15° of rotation compared to the opposite knee.
Internal rotation (medial rotation or intorsion) is rotation towards the axis of the body, [22] carried out by internal rotators. External rotation (lateral rotation or extorsion) is rotation away from the center of the body, [22] carried out by external rotators. Internal and external rotators make up the rotator cuff, a group of muscles that ...
