Introduction

Overhead throwing places exceptionally high stresses on the shoulder. The thrower's shoulder must be loose enough to allow excessive external rotation but stable enough to prevent symptomatic humeral head subluxations, requiring a delicate balance between mobility and functional stability. This balance is frequently compromised and believed to lead to various types of injuries to the surrounding tissues.

Further Information

The majority of patients who have been identified as having internal impingement are overhead athletes or throwing athletes (tennis, volleyball players, swimmers, or baseball players). Please redirect your reading to Internal Impingement of the Shoulder and Throwing biomechanics
