BACKGROUND: Unintentional musculoskeletal injury has a significant impact on military personnel which is amplified in U.S. Navy Sea, Air, and Land Operators who participate in year round physical and tactical training. Full recovery from injury including restoration of strength is necessary for safe participation in training and performance of missions. Inadequate recovery may predispose the Op...

The conventional perspective has been that capsuloligamentous structures act as a mechanical restraint to humeral translation at the shoulder. Although this is true, the capsuloligamentous structures also have a sensorimotor influence on the musculoskeletal system, providing stability at the shoulder. The purpose of the current study was to discuss the sensorimotor role that the capsuloligament...

Shoulder joint is a complex integration of soft and hard tissues. It plays an important role in performing daily activities and can be considered as a perfect compromise between mobility and stability. However, shoulder is vulnerable to complications such as dislocations and osteoarthritis. Finite element (FE) models have been developed to understand shoulder injury mechanisms, implications of ...

A 6-year-old girl fell off a climbing frame and injured her left shoulder. She was seen the same day in the accident and emergency (A&E) department with diffuse left shoulder pain. On examination diffuse swelling of the shoulder was noted but no deformity was discernible. All movements of the shoulder were grossly restricted and painful. An initial X-ray (Fig. 1) showed a Salter-Harris Type II ...

The shoulder is the most mobile joint in the human body. The cost of such versatility is an increased risk of injury. It is important that family physicians understand the anatomy of the shoulder, mechanisms of injury, typical physical and radiologic findings, approach to management of injuries, and indications for referral. Clavicle fractures are among the most common acute shoulder injuries, ...

T he glenohumeral joint is the most mobile and one of the most frequently dislocated joints in the human body. Before skeletal maturity, shoulder dislocations are less frequent, and shoulder trauma more often results in fracture through the proximal humeral physis. In a recent epidemiologic study, Zacchilli and Owens found that shoulder dislocations follow a bimodal distribution, with 46.8% occ...

The shoulder (glenohumeral) joint has the greatest range of motion of all human joints; as a result, it is particularly vulnerable to dislocation and injury. The ability to accurately measure dynamic in-vivo joint kinematics in 6-Degrees-of-Freedom (6-DOF) (translations and rotations) and subsequently quantify articular cartilage contact patterns of that joint has been and remains a difficult b...

Manual wheelchair users with spinal cord injury (SCI) have a high prevalence of shoulder pain due to the use of the upper extremity for independent mobility, transfers, and other activities of daily living. Indeed, shoulder pain dramatically affects quality of life of these individuals. There is limited evidence obtained through radiographic techniques of a relationship between the forces actin...

Acromioclavicular (AC) joint injuries account for approximately 3-5% of shoulder girdle injuries (Rockwood et al., 1998). Depending on severity of injury and direction of displacement these are classified using Rockwood classification system for AC joint dislocation. We present an unusual case presenting with locked superior dislocation of the AC joint highlighting the presentation and subseque...

Purpose: Sub-acromial impingement syndrome [SIS] is one of the most common causes of shoulder pain, which affects shoulder joint proprioception. Closed kinetic chain [CKC] exercises with a Sling are more effective and safer than open kinetic chain [OKC] exercises. This study aimed to compare the efficiency of OKC and Sling exercises [TRX] on shoulder sense position joints in overhead athletes w...
