Multidirectional Instability of the Shoulder
The shoulder is unique in that it is the most mobile joint in the human body. It serves primarily to position the hand in space and thus requires a delicate…
Posterior Shoulder Instability
Compared with anterior shoulder instability, posterior instability is relatively uncommon, occurring in 2% to 10% of cases. Electrocution and convulsive seizures are rare causes of posterior shoulder dislocation reported in…
Anterior Shoulder Instability
Anterior shoulder instability is the most common type of shoulder instability. It is typically the result of a traumatic event with dislocation of the glenohumeral joint. However, instability also may…
Shoulder Arthroscopy
Background Shoulder arthroscopy was first described in the 1930s by Burman, who learned how to perform arthroscopy on cadaveric joints. Remarkably, shoulder arthroscopy has been used regularly for only the…
Proprioception and Joint Dysfunction
Proprioception of the Knee Anterior cruciate ligament (ACL) injury results in functional instability because of the increased translation of the tibia on the femur, as well as the rotatory instability…
Modalities in Sports
The use of modalities or physical agents as an intervention for the treatment of sports-related injuries has been a staple since the beginning of sports themselves. These procedure-based treatments have…
Injury Prevention
This chapter emphasizes four specific areas that are often the focus of injury prevention protocols: the hamstrings, spine, anterior cruciate ligament, and ankle. Hamstring Strains Roald Bahr Muscle injuries occur frequently…
Shoulder Diagnosis and Decision Making
Because the shoulder is a complex joint that contains many anatomic structures and articulations capable of causing pain, the evaluation of a patient whose chief complaint is shoulder pain can…
Basics of Taping and Orthotics
Taping During physical activity, the integrity of a joint and its associated structures can be compromised, especially during high-risk activities that may introduce injurious mechanisms. Sports medicine clinicians can supplement…
Shoulder Anatomy and Biomechanics
The shoulder can really be considered a complex ( Fig. 42-1 ), consisting of four joints or articulations (all with important stabilizing ligaments), two spaces, and more than 30 muscles…
