The tibiofemoral (knee) joint allows 2 degrees of freedom, flexion and extension, and internal and external rotation. -elbow is comprised of 3 synovial joints, surrounded by 1 capsule - proximal radioulnar joint functions as part of the forearm-serves as middle link in UE kinematic chain For more in-depth information on each study, the reader is referred to the reference list at the end of this chapter. Most of the studies from which data were derived were performed in healthy adults, although some data were obtained from elderly and pediatric subjects. During pronation and supination of the forearm, motion occurs at the proximal and distal radioulnar joints simultaneously. Elbow and radio-ulnar arthrokinematics applying the rules of concavity and convexity to the humero-ulnar joint: in an open chain, concave ulnar surface rolls … When the forearm is fully supinated, the radius and the ulna lie parallel to each other. The proximal radioulnar joint is located anatomically within the capsule of the elbow joint and consists of the articulation between the rim of the radial head and the fibro-osseous ring formed by the annular ligament and the radial notch of the ulna (Fig. BASIC ANATOMY OF WRIST JOINT Wrist joint is a synovial joint of ellipsoid variety between lower end of radius and three lateral bones of proximal row of carpus.

The annular ligament is attached to the anterior and posterior margins of the radial notch of the ulna and encircles the radial head, holding it firmly against the radial notch (see Figs. The radial head spins anteriorly during pronation and posteriorly during supination. 4-8 Elbow and forearm motion required to comb one’s hair. Elbow and forearm motion required to comb one’s hair. For more complete coverage of the structure and function of the low back and pelvis, Kinesiology – The Skeletal System and Muscle Function, 3 rd ed. For example anywhere on the body, there are two parallel forces F acting in the plane of motion of a body. Elbow extension ROM is limited by contact of the olecranon process of the ulna with the olecranon fossa of the humerus.10 Information regarding normal ROM for the elbow is located in Appendix B. FOREARM JOINTS OSTEOKINEMATICS ulna and radius pronate with respect to - articular disc of the inferior radioulnar joint. At the extremes of flexion and extension, rolling motions of the ulna and radius replace the gliding motion.13,28 Bony anatomy of the joints of the elbow—posterior view. yes: Term. 4-4) collateral ligaments, respectively. There are two kinds of osteokinematics: Active range of motion (AROM) and passive range of motion (PROM). Lower – scaphoid ; lunate ; triquetral bones. Elbow and forearm motion required to eat with a spoon. As the forearm pronates, the radius crosses anteriorly over the surface of the ulna. Fig. soft tissue stretch. Supination of the forearm is limited by tension in ligamentous structures (anterior radioulnar ligament and oblique cord). Fig. Fig. - wrist & hand Flexion extensors Ant. -open pack: 60-70 flex -closed pack: full ext with supination -capsular pattern: flexion> extension Of 50 subjects examined, 49 were able to perform all 12 functional activities included in the study, with elbow motion limited to a range of 75 degrees to 120 degrees of flexion. Elbow/Forearm Rom Requirements For Functional Activities. During pronation and supination of the forearm, motion occurs at the proximal and distal radioulnar joints simultaneously. Numerous other investigators have attempted to quantify the amount of elbow and forearm motion required to perform various functional activities.3,6,14,15,19,20,22–24 A summary of elbow and forearm range of motion related to various functional activities is provided in Table 4-1. Capsular restrictions of forearm ROM result in relatively equal deficits of forearm pronation and supination.4,9. 4-7 Anatomy of the middle radioulnar union. 4-1 Bony anatomy of the joints of the elbow—anterior view. 4-7 Anatomy of the middle radioulnar union. Because bony contact limits pronation, the normal end-feel for that motion is hard. Elbow flexion and extension may be measured with the patient in the upright (standing or sitting), supine, or side-lying position. Elbow flexion range of motion (ROM) is limited by soft tissue approximation between the structures of the anterior arm and the forearm, particularly during active flexion of the joint when contact between contracting flexors of the arm and forearm stops the motion. Most functional activities require a fairly large amount of elbow flexion ROM (Figs. - triceps brachii, anconeus Agon. Distally, the concave ulnar notch of the radius rolls and slides anteriorly on the ulnar head during pronation and posteriorly during supination.21 Although the elbow joint traditionally has been classified as a hinge joint, the hinge component occurs at the humeroulnar articulation, and the humeroradial joint is classified as a plane joint. The dorsal and palmar radioulnar ligaments assist in stabilization of the distal radioulnar joint.11. Both proximal and distal radioulnar joints are classified as pivot joints, allowing rotation of the radius around the ulna in a transverse plane. Because of the multiple joints involved during shoulder movement, it is prudent to refer to the area as the shoulder complex. wind up (see below); cocking; acceleration; deceleration; follow-through ; Biomechanics. crosses anteriorly to glenohumeral joint's the joint surfaces while other positions are looser. Osteokinematics of the Tibiofemoral Joint. • Stability for the elbow joint depends upon the configuration of the joint surfaces, the ligaments, and joint capsule. Essentials of the study populations and the instrumentation used are included in the table. 4-7).17 Ligamentous reinforcement of the proximal radioulnar joint occurs via two ligaments. Within the elbow joint capsule are three articulations, two that make up the elbow joint complex and one that is part of the forearm complex. If elbow flexion is more restricted than elbow extension, then a capsular pattern is present, and involvement of the capsule should be suspected.4,9 Ligamentous reinforcement of the elbow joint occurs primarily on the medial and lateral sides of the joint via the ulnar (Fig. Bony anatomy of the joints of the elbow—anterior view.
