Participation in combat sports continues to rise in the United States, especially in younger populations. According to an ESPN survey, 5.5 million teens and 3.2 million kids under 13 years-of-age, perform some type of mixed martial arts (MMA)(1). The incidence of injury from participation in MMA is between 22.9 and 28.6 per 100-fight encounters(1). Because more... MORE

In part two of this series, Chris Mallac outlines the imaging/radiology techniques used when diagnosing brachial plexus injuries, and the typical injury-management protocols. Recapping from part one, brachial plexus injuries (commonly known as‘stingers’ and ‘burners’) typically occur as a result of a fall onto the shoulder (such as falling from a bike or horse), contact...

Admittedly most soccer related injuries are to the lower extremities. However a recent study by researchers at Brown University found that a rising number of soccer related injuries are suffered in the upper extremity(1). The study evaluated a sample of 100 hospital emergency departments from 1999 to 2016 and found that nearly a quarter (20.4%)... MORE

Chris Mallac describes the anatomy and biomechanics of the infraspinatus, outlines some common injury mechanisms, and provides rehab ideas to improve strength and range of motion in this muscle. The infraspinatus (IS), a muscle of the glenohumeral joint, has multiple functions. These include shoulder external rotation, abduction, and stabilization. It works in conjunction with the... MORE

Chris Mallac discusses the pathophysiology of brachial plexus injuries, how they occur in high-risk sports, and the typical signs and symptoms suffered by the athlete. Brachial plexus injuries (BPI) are a reasonably common injury in contact-sport athletes. These are typically referred to as ‘stingers’ and ‘burners’, and represent a transient and reversible peripheral neuropraxia of all... MORE

The shoulder’s rotator cuff consists of four small muscles doing a big job. Known as the SITS muscles, the supraspinatus, infraspinatus, trees minor, and subscapularis help keep the free-moving ball end of the humerus in the shallow glenoid fossa of the scapula (see figure 1). They attach on the ventral, dorsal, and superior portions of... MORE

In a previous article, Chris Mallac explored the unique anatomical and biomechanical features of the subscapularis, the common injury patterns associated with this muscle and the important role it has in shoulder stability. In this article, Chris outlines the classical signs and symptoms of subscapularis injury and provides rehabilitation ideas for injured and dysfunctional subscapularis... MORE

The subscapularis is the largest and most powerful muscle of the rotator cuff, and an important anterior stabiliser of the humeral head. With that in mind, Chris Mallac explores the anatomy and biomechanics of subscapularis in the first of two articles, including the most common injury presentations. Direct injuries to the muscle-tendon unit of the subscapularis... MORE

In today’s feature article, Chris Mallac explores the impact of axillary nerve injury. Damage to the axillary nerve occurs in athletes via a stretch from a fall or shoulder dislocation, compression, trauma, or as an unwelcome result of shoulder surgery. This peripheral nerve injury decreases both the strength around the shoulder, as the nerve innervates... MORE

The axillary nerve provides both motor innervation and sensation to the upper arm. Injury to this nerve, as described by Chris Mallac, presents athletes in contact sports with significant deficits. Athletes who participate in contact sports such as football, rugby, ice hockey and wrestling, are particularly vulnerable to injuries to the axillary nerve(1,2). Common mechanisms... MORE
