Injury of the Subscapularis Tendon

Injury of the subscapularis tendon

The subscapularis muscle (which originates on the inner surface of the scapula, runs anterior to the shoulder joint, and is inserted high into the anterior aspect of the head of the humerus) is the most important internal rotator of the upper arm. Its tendon can be affected by partial or […]

Etiology of Running Injuries

The etiology of running injuries is multifactorial. Factors may be extrinsic or intrinsic.

Running

Running is an effective way to exercise large muscle groups and has a documented effect in the preservation of health and in the prevention of cardiovascular problems. However, it is a potentially harmful activity, and running injuries are common—although 2–2.5 times […]

Insertionitis (Tenoperiostitis)

Attachment of a muscle to bone involves a gradual transition from muscle-tendon to cartilage and from mineralized cartilage to bone. Bone-tendon junctions are poorly supplied with blood because the fibrocartilage creates a ‘barrier’; this may explain why these injuries often take a long time to heal and may become chronic.

Inflammation of the muscle-tendon attachment […]

Peritenonitis (Peritendinitis)

Repetitive one-sided movements or persistent mechanical irritation may cause an inflammatory reaction in the tendon sheath, and a minor inflammatory reaction in the tendon itself. The condition frequently becomes chronic and can be difficult to treat.

Location

The Achilles tendon peritenon is mostly affected, along with the sheath and the tendons of the long head […]

Classification of Tendon Injuries

‘Tendinitis’ has been the clinical term traditionally applied to virtually all painful tendon structures, including the tendon, the synovial sheath, and the adjacent bursa. It has, however, been established that there is only a limited inflammatory response in the tendon to injury. Injuries are most often associated with a degenerative process, which increases with age […]

Myositis

Myositis or muscle inflammation is rare; it mainly affects the muscles of the thigh, back, shoulder, and calf.

Symptoms and diagnosis

The following may suggest a diagnosis of myositis: – pain in the affected muscle group on exertion; – symptoms increasing as effort becomes more intensive and repetitive; – tender, firm areas felt on examination […]

Intermuscular Hematoma

Bleeding may occur between muscles when a muscle fascia and its adjacent blood vessels are damaged. After an initial increase, causing the bleeding to spread, the pressure falls quickly. Typically, bruising and swelling, caused by a collection of blood, appear distally to the damaged area 24–48 hours after the injury, due to gravity. Because there […]

Ligament injuries

Ligament injuries in athletes are common, particularly around the knee and the ankle. They also occur in the shoulder, elbow, and thumb

Functional anatomy

Ligaments are attached to the two bones that compose the joint . Ligaments provide stability to the joint, while still allowing motion. They cannot actively resist motion, but provide a ‘check […]

A Patient’s Guide to Joint Injections for Arthritis

Doctors recommend injections of corticosteroids (also commonly known as cortisone) for many arthritis patients. Cortisone is a powerful anti-inflammatory medication that can reduce joint inflammation. Because the medication is injected directly into the joint, the effects of the medication are concentrated on the painful joint. The injected cortisone can bring the inflammation in the joint […]

A Patient’s Guide to Fibromyalgia

Introduction

Fibromyalgia, though common, is a disease that’s not well understood. It involves widespread pain throughout the body, with especially tender spots near certain joints. The pain stops people with fibromyalgia from functioning normally, partly because they feel exhausted most of the time. Fibromyalgia is a chronic (meaning long-lasting) condition that usually requires many years […]
