Passive pronation

Procedure.

Perform an adduction movement in the shoulder: the hand pulls the inner side of the foot downwards while the thumb pushes the outer side upwards.

Common mistakes.

The ankle and subtalar joints are not stabilized.

Normal functional anatomy:

• Range: 30-60° • Elld-feel: soft ligamentous • Limitiug structures: medial and dorsal midtarsal ligaments.

Passive pronation

Positioning.

The subject stands with the arm hanging and the elbow bent to a right angle. The examiner stands in front of the subject. Both hands encircle the distal forearm in such a way that the heel of the contralateral hand is placed against the volar part of the ulna and the fingers of the […]

Elbow, wrist and hand

Wrist and hand rehabilitation

Because the function of the wrist and hand is essential to daily activities, special care is needed to avoid compromising the functional integrity of these structures. In addition to range-of-motion and strengthening exercises, attention should be paid to dexterity exercises and to tactile senses. The wrist and hand are a series […]

Entrapment of the Median Nerve (Pronator Teres Syndrome)

The median nerve runs in front of the elbow joint and past the pronator muscle. Entrapment of this nerve is a rare condition in sport.

Symptoms and diagnosis

– Pain and tenderness occur in the middle anterior aspect of the elbow. – Numbness is felt in the second and third fingers, and in the radial […]

Triangular Fibrocartilage Complex Tear

Basics

Description The TFCC: A group of ligaments and cartilaginous structures that stabilize the distal radioulnar joint during pronation and supination of the forearm Extends from the ulnar styloid to the sigmoid notch of the distal radius Central portion: More cartilaginous than its periphery Acts as a meniscal homolog, similar to the menisci of the […]

Tennis Elbow

Basics Description Lateral epicondylitis (tennis elbow) is a tendinopathy of the origin of the ECRB tendon. The lateral epicondyle is the origin of the common wrist extensor tendon, including: ECRL ECRB Extensor digitorum communis Extensor carpi ulnaris The ECRB lies beneath the ECRL. These extensors stabilize the wrist and are used in sports (such […]

Talus Fracture

Basics Description The talus, a small bone in the hindfoot: Articulates with the calcaneus and the remainder of the midfoot bones Supports the body’s weight and distributes the body’s forces to the foot Is critical to proper function of the foot Is covered (~60%) with articular cartilage Is vascularly supplied by vessels through a […]

Elbow Anatomy and Examination

Basics Description Bones Ulnohumeral joint: The trochlea of the humerus articulates with the trochlear notch of the proximal ulna. The olecranon process of the ulna lies posterior to the joint. Allows for elbow flexion and extension Radiohumeral joint: The capitulum of the humerus articulates with the radial head. Allows for forearm supination and pronation […]

Ankle Fracture

Basics Description Fractures of the distal end of the fibula and tibia are termed ankle fractures. Usually caused by the twisting of the body around a planted foot or a misstep that results in overstressing the ankle joint Severe fractures may result in dislocation of the ankle. 2 fracture classification systems are used currently: […]
