The rupture occurred in a proximal biceps tendon, resulting in retraction distally. This is one of the two forms of the "Popeye deformity." This image shows a biceps brachii tendon rupture on the left arm. The rupture occurred in the distal biceps tendon, resulting in retraction of the muscle belly proximally.
Muscle weakness is a lack of muscle strength. Its causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy.
The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso) and distal muscles (close to hands or feet), most apparent in the finger flexors and knee extensors. [3] IBM is often confused with an entirely different class of diseases, called hereditary inclusion body ...
The Preacher curl, also known as the Scott Curl, is a popular exercise for biceps. The proximal tendons of the biceps brachii are commonly involved in pathological processes and are a frequent cause of anterior shoulder pain. [18] Disorders of the distal biceps brachii tendon include insertional tendonitis and partial or complete tears of the ...
Denervation can occur as a consequence of nerve injury. The three primary categories of nerve injury are neurapraxia, axonotmesis, and neurotmesis, each corresponding to varying degrees of damage and potential for recovery. In cases of nerve injury, the brain demonstrates an impressive ability to rewire or reorganize its neuronal circuitry ...
Biceps femoris tendon rupture can occur when the biceps femoris is injured in sports that require explosive bending of the knee as seen in sprinting.If the athlete is fatigued or has not warmed up properly he/she may suffer a hamstring strain/rupture, which is the tearing of the hamstring muscle.
Structures found in the posterolateral corner include the tibia, fibula, lateral femur, iliotibial band (IT band), the long and short heads of the biceps femoris tendon, the fibular (lateral) collateral ligament (FCL), the popliteus tendon, the popliteofibular ligament, the lateral gastrocnemius tendon, and the fabellofibular ligament.
The overuse of the coracobrachialis can lead to stiffening of the muscle. Common causes of injury include chest workouts or activities that require one to press the arm very tight towards the body, e.g. work on the rings in gymnastics. [8] Symptoms of overuse or injury are pain in the arm and shoulder, radiating down to the back of the hand.
