Shoulder Injuries
 
Shoulder injuries appear in a wide range of sport activities and are caused either by over-use and exhaustion of the shoulder, or by accidents. The frequency of shoulder injuries are attributed to the anatomical structure of the shoulder joint - the ratio between the round structure of the upper arm’s head bone and the flat nature of the shoulder blade is 1:4; the entire joint is built horizontally, meaning, gravity is working against it (unlike the knee joint which has gravity working for it and giving it stability.) All of these factors make the shoulder joint extremely vulnerable.

Basketball, volleyball and tennis players are especially vulnerable to shoulder injuries due to their excessive and repetitive usage of the arm.

We also see a high number of shoulder injuries among cyclists, especially extreme cyclists, caused mainly due to fallings. Weight lifters and martial arts athletes - judo, wrestling etc. - suffer from high number of shoulder injuries.

The most common shoulder injury is dislocation: the upper arm bone slips out of its socket and is left hanging on ligaments and muscles alone. The relocating must be carried out by a doctor.
Common Causes for Shoulder Injuries
Treatment
Dislocation of the shoulder: after the relocating the shoulder joint must be stabilized so the dislocation won’t occur again. The relocating is performed under local anaesthesia, sometimes without anaesthesia at all, but this is not the end of the treatment. Due to the dislocation the ligaments that hold the upper arm bone in its place are loosened, lengthened and become detached from the bone. If nothing is done the shoulder is actually not properly held in its place and the chance for repeated relocating is higher than ever. The way to prevent repeated relocation is by arthroscopic surgery during which the ligaments are restored by tying them back to the shoulder blade and stretching them until the optimal point where the shoulder joint is held in its exact place. This type of procedure is the only sure way to prevent repeated dislocation of the shoulder.

There are more severe cases in which during the dislocation the ligament is completely torn, including a partial breakage of the blade itself, and in cases that the athlete had been operated on already for shoulder relocating and the surgery wasn’t successful. In such cases there is a need to relocate parts of the bone and ligament in order to fix the damage (Latarget operation.)

The procedure is performed using the arthroscopic method: three to four 8mm cuts are done, through which bone canals are carved or anchors transplanted. The anchors hold the stitches, allowing to attach the tendon back to the bone. The speciality instruments for this sort of operation are manufactured in Israel by TAG Medical Instruments.
