Summary
Posterior shoulder instability, often missed in athletes, may require surgical intervention if physical therapy for at least six months fails to resolve symptoms.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanics
Background:
- Posterior shoulder instability is a frequently misdiagnosed condition in competitive athletes.
- This condition can significantly impact athletic performance and requires accurate diagnosis.
Purpose of the Study:
- To review the existing literature on posterior shoulder instability.
- To identify diagnostic and treatment considerations for athletes with this condition.
Main Methods:
- A comprehensive clinical review of relevant studies was conducted.
- Literature search was performed using PubMed and Cochrane databases, covering studies from 1950 to 2010.
Main Results:
- A total of 107 studies met the inclusion criteria for the review.
- The reviewed studies highlight the challenges in diagnosing posterior shoulder instability.
Conclusions:
- Surgical stabilization should be considered for athletes with persistent posterior shoulder instability symptoms after a minimum of six months of physical therapy.
- Treatment should be tailored to the specific underlying pathology causing the instability.

01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:22Mitral Valve Prolapse II: Assessment and Management
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.
