Elbow Biomechanics: Soft Tissue Stabilizers. Extension in the humeroulnar joint is produced by the triceps brachii and anconeus muscle, with a tiny contribution from the muscles arising from the lateral epicondyle of the humerus, such as the extensor digitorum muscle. A subluxation of the humeroradial joint is called a "nursemaid's elbow", also known as radial head subluxation.It is generally caused by a sudden pull on the extended pronated forearm, such as by an adult tugging on an uncooperative child or by swinging the child by the arms during play.. doi: 10.1016/j.jse.2004.09.032.

So, let's try out the quiz. The elbow joint is a trochoginglymoid joint: that is, it has flexion-extension [ginglymoid] motion at the ulnohumeral and radiocapitellar articulations and pronation and supination [trochoid] motion at the proximal radioulnar joint. The passive stabilizers include the bony articular geometry and the soft tissue stabilizers. Nishida K, Hashizume K, Nasu Y, Ozawa M, Fujiwara K, Inoue H, Ozaki T. Bone Joint J. When the forearm is extended and supinated, the axis of the arm and forearm are not in the same line; the arm forms an obtuse angle with the forearm, known as the carrying angle. [2][page needed] Owing to the obliquity of the trochlea of the humerus, this movement does not take place in the antero-posterior plane of the body of the humerus. 2005 Jan-Feb;14(1 Suppl S):179S-185S.

The biomechanics of the elbow joint can be divided into kinematics, stabilizing structures in elbow stability, and force transmission through the elbow joint. Coactivation of the agonist–antagonist group (biceps, brachialis, and triceps) acts to center joint forces within the available articular arc of the ulnotrochlear joint [24, 25], while activation of the wrist extensors acts to center the radial head on the capitellum [15, 26]. Author information: (1)American Sports Medicine Institute, 1313 13th Street, South Birmingham, AL 35205, USA. The humeroulnar joint (ulnohumeral or trochlear joint[1]), is part of the elbow-joint.

The elbow joint is a complex structure that provides an important function as the mechanical link in the upper extremity between the hand, wrist and the shoulder. • They provide mobility for the hand in space by shortening and lengthening the upper extremity. Biomechanics is the science of movement that deals with muscles, bones, tendons, and ligaments as well as help to understand the mechanical principles of bones and joints. Without the elbow the enormous range of movement possible at the shoulder would only give the hand access to a shell of fixed distance from the shoulder articulation, with limited capacity to … All different strokes in tennis have a different repetitive biomechanical nature that can result in tennis-related injuries.

NIH Mid-term results of alumina ceramic unlinked total elbow arthroplasty with cement fixation for patients with rheumatoid arthritis. N2 - A clear understanding of the unique anatomic features of the elbow joint aids in a more full appreciation of the biomechanical aspects of this joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. INTRODUCTION • The elbow complex includes the elbow joint ( Humeroulnar & Humeroradial joints) and the Proximal & Distal radioulnar joint. T1 - Biomechanics of the elbow joint in tennis players. Because elbow joint motion occurs about a nearly perfect hinge axis through the center of the capitellum and trochlea, the posterior bundle of the medial collateral ligament complex will be taut at different positions of elbow flexion . Biomechanics is the term used to describe the movement of the body. I.A.Kapandji, Second Edition, Churchill Livingstone, 1970 4.
