Shoulder problems in overhead sports. Part I - biomechanics of throwing.

The article discusses the biomechanical processes that occur during an overhead throw. This activity is highly specialized and requires full and proper function from the shoulder joint. It consists of active and passive stabilization and synchronous work of the accelerating and decelerating muscles. The process of the overhead throw can be divided into several phases that differ from each other in biomechanical parameters and involvement of specific muscles.

In the past, the procedure for rehabilitation after hip surgery, related to the long immobilization of the operated joint, was often delayed and limited in time. Today's surgical procedures and rehabilitation allows for a quicker return to full physical fitness. Postoperative physiotherapy is mainly focused on regaining full joint function (range of motion--ROM, strength, stability). The rehabilitation program must be a dynamic process, dosed up to the possibility of the patient, depending on the type of procedure performed. Rehabilitation must take into account not only the type of procedure performed intraarticular, but also surgical approach. Rehabilitation after surgery requiring dislocation of the hip by osteotomy with simultaneous artrotomii trochanter must take into account the time required for the stable union. Range of motion exercises begin in the first days after surgery using a continous passive movement (CPM) and passive exercises, and later a stationary bicycle. Menaging patients after treatment of CAM type femoroacetabular impingement is dependent on the degree of bone resection performed within the femur. In the treatment of Pincer-type f emoroacetabular impingement, as well as injuries of the hip labrum rehabilitation proceedings must take into account the location and the area of pathology. Rehabilitation after surgery for articular cartilage (chondroplasty or osteoplasty) in the first period is mainly focused on the avoidance of intraarticular conflicts in the reconstruction of the full ROM.
