Applied anatomy and biomechanics of the elbow joint. title = "Applied anatomy and biomechanics of the elbow joint.". Anatomy and They are both extracapsular. They are both syndesmosis connections. 3.90). Fig 1 Humeroulnar and humeroradial joints (anterior view). The dotted line shows the insertion of the joint capsule. ONLINE Applied anatomy of the sacroiliac joint 41. There are, of course, individual differences. The functional anatomy of the elbow joint complex is unique in orientation and configuration. Disorders of the sacroiliac joint 44. 307). It includes two articulations : (a) humero-ulnar articulation, between the trochlea of the humerus and trochlear notch of the ulna, and (b) humero-radial articulation, between the capitulum of the humerus and the head of radius. 315) and the oblique cord join the two bones of the forearm to prevent any longitudinal movement and assist as a fulcrum in pronation–supination (i.e. This unique osseous structure provides … These ligaments help to maintain the articular surfaces in contact with each other. TY - JOUR T1 - Applied anatomy and biomechanics of the elbow joint. It is attached to the lower end of humerus in a continuous line, which excludes the two epicondyles but include three fossae. The end-feel of this movement is hard. The functional anatomy of the elbow joint complex is unique in orientation and configuration. 1). • The oblique cord extends inferolaterally from the lateral border of the tuberosity of the ulna to the radius, just below its tuberosity (see Putz, Fig. Articular surfaces: Elbow joint consists of two articulations. The three joints lie within the same lax joint capsule, which is spanned by muscular fibres of the brachialis, triceps and anconeus muscles. It consists of three ‘joints’, which lie within one joint capsule and together have two separate functions. Subcutaneous bursitis: Repeated friction and pressure on the bursa can cause it to become inflamed. http://www.anatomyzone.com3D anatomy tutorial on the features of the elbow joint using the Zygote Body Browser (http://www.zygotebody.com). The articulation between the trochlea and ulna is so shaped as to allow no lateral motion, but only an anteroposterior one. The elbow joint is one important joint in our body that is found where the humerus, ulna and radius bones meet. Upper: 1, anterior part; 2, middle part; 3, posterior part; 4, ligament of Cooper. 5). The three ‘joints’ are the humeroulnar, the humeroradial and upper radioulnar joint (Figs 1–3, see Putz, Fig. Applied anatomy and biomechanics of the elbow joint. 3.93). The elbow's functions include positioning the hand in space for fine movements, powerful grasping and serving as a fulcrum for the forear … Cushions of extra-synovial fat fill up the three … Anatomy Sport-specific applied anatomy of the elbow joint complex can be broken down and divided into osseous, capsuloligamentous, musculotendinous, and neurologic components. This overextension is the result of the format of the olecranon fossa and process. 315). 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. • The humeroradial joint – a ball-and-socket joint – consists of (a) the spheroidal capitulum of the humerus and (b) the proximal surface of the head of the radius. 77 The ulnohumeral joint resembles a hinge (ginglymus), allowing flexion and extension. 3.89) and the olecranon fossa (dorsal aspect) (see Gosling et al, Fig. The main factors involved in malformations of the limbs (O'Rahilly and Müller, 1996) are dominant and recessive genes, chromosomal abnormalities, drugs (e.g., thalidomide), and (in a few instances) amniotic bands. Because it articulates with the capitulotrochlear sulcus at the ulnar side, it allows pronation–supination movements as well. The elbow joint is a synovial joint found in the upper limb between the arm and the forearm. The mean degree of elbow joint laxity … Dive into the research topics of 'Applied anatomy and biomechanics of the elbow joint.'. Interpretation of the clinical examination of the sacroiliac joint and coccyx 43. On radius: 9, radial head. FIG.330– Left elbow-joint, showing posterior and radial collateral ligaments.The Anterior Ligament (Fig. The elbow joint helps the hand to approach or move away from the body, whatever the arm position resulting from shoulder movement. Their two functions are flexion/extension, which is performed at the humeroulnar and humeroradial joints, and pronation/supination, which takes place at the upper radioulnar joint in close association with the lower radioulnar joint. First, the large spherical head of the humerus articulates against the small shallow glenoid fossa of the scapula (only 25–30% of the humeral head is covered by the glenoid surface). Together they form a unique fingerprint. In its anterior course, the axis of movement is horizontal: therefore, in flexion, the forearm lies exactly in front of the upper arm. The elbow joint helps the hand to approach or move away from the body, whatever the arm position resulting from shoulder movement. Abstract Knowledge of the anatomy and surgical approaches is crucial to develop a surgical strategy while minimizing complications. The elbow is a seemingly simple joint. The elbow joint helps the hand to approach or move away from the body, whatever the arm position resulting from shoulder movement. 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. By continuing you agree to the use of cookies. • The quadrate ligament attaches the radial neck to the distal aspect of the radial notch of the ulna. The main action of the humeroulnar joint is flexion and extension of the elbow. The mean valgus and varus deviation of the elbow joint was 11.2 (6.4 16.1 ) and 6.6 (3 10.7 ), respectively. Studies on the elbow joint are now especially pertinent because of the increasing interest in congenital anomalies of the skeleton. This rotation is easily noticed during activities such as hand-to-mouth eating motions. 329).—The anterior ligament is a broad and thin fibrous layer covering the anterior surface of the joint. This facet exactly follows the shape of the humeral capitulum. 4): Fig 4 The medial (upper) and radial (lower) collateral ligaments. Three bones, the ulna, radius, and humerus, articulate to form four articulations: the humeroulnar, humeroradial, superior radioulnar, and inferior radioulnar joints. It is the point of articulation of three bones: the humerus of the arm and the radius and the ulna of the forearm. On ulna: 1, trochlear notch; 2, coronoid process; 3, olecranon process; 4, radial notch; 5, ulnar tuberosity. Second, the bony surfaces of the joint are largely incongruent (flat glenoid and round humerus). This knowledge may, it is hoped, be translated into a broader understanding of the scientific basis of the management of elbow problems. journal = "Instructional course lectures". Research output: Contribution to journal › Article › peer-review. Stability of Elbow Joint  The elbow joint is stable because  of the wrench- shaped articular surface of the olecranon and the pulley-shaped trochlea of the humerus;  strong medial and lateral ligaments. We applied 160 N of axial force during cyclic and functional range of forearm rotation (40 o pronation/40 o supination), and force, contact pressure, and contact area through the elbow joint were measured simultaneously. On radius: 6, circumference; 7, articular facet; 8, radial tuberosity. The forearm then usually lies in line with the upper arm, except in most women and in some men, in whom the elbow may sometimes overextend. Fig 3 Upper radioulnar joint. Fig 2 Humeroulnar and humeroradial joints (posterior view). The Anatomy of the Elbow The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. diagonal rotation). The coronoid fossa, into which the coronoid process of the ulna fits, as is the case for the olecranon fossa and olecranon process, together with the forward projection of both the lower humeral and the upper ulnar extremities, allows a considerable range of flexion–extension between forearm and upper arm. FIBROUS CAPSULE Fibrous capsule completely envelop the joint. Humero-radial articulation is between the capitulum of humerus and superior surface of head of radius. On humerus: 1, trochlea; 2, coronoid fossa; 3, medial epicondyl; 4, capitulum; 5, radial fossa; 6, capitulotrochlear sulcus. The radiohumeral and proximal radioulnar joint allows axial rotation or a pivoting (trochoid) type of motion. LIGAMENTS OF ELBOW JOINT  Capsular ligament  Ulnar collateral ligament or Medial ligament  Radial collateral ligament or Lateral ligament 9. It has the appearance of a plain hinge between 3 bones, the humerus above and the ulna and radius below (Fig. It consists of three ‘joints’, which lie within one joint capsule and together have two separate functions. The unique positioning and interaction of the bones in the joint allows for a small amount of rotation as well as hinge action. The distal extremity of the humerus is a fork, the axis of its articular surfaces running through the humeral capitulum and trochlea. Fig 5 The physiological valgus position. All three parts are reinforced by an oblique band (ligament of Cooper) distally on the ulna. The capsule is reinforced by strong lateral ligaments (Fig. Around the surgical neck of the humerus and the glenohumeral joint , there are anastomotic contributions coming from the second and third part of the axillary artery. / Morrey, B. F. T1 - Applied anatomy and biomechanics of the elbow joint. The articular surfaces on the humerus are the spool-shaped trochlea with, proximal to it, the coronoid fossa (ventral aspect) (see Gosling et al, Fig. Anatomy of the Elbow Joint The three bones that are responsible for the formation of the elbow joint are humerus , radius and ulna . On ulna: 3, olecranon process. On ulna: 7, coronoid process; 8, radial notch. The elbow joint is classified structurally as a synovial joint. 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.

The articulation between the capitellum and upper surface of the head of the radius is, on the contrary, a ball-and-socket joint. Fig 6 The range of flexion–extension movement. The prominent medial and lateral epicondyles serve as the attachment point for the medial collateral ligament (MCL), the flexor pronator group and lateral collateral ligament complex (LCL), … publisher = "American Association of Orthopaedic Surgeons". The most widely used approaches of the elbow will be reviewed with an emphasis on how to extend the approaches if so needed and according to which exposures are best used for the most common elbow pathologies. AB - 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. The articular facet of the radius, with which the proximal part of the humeroradial joint articulates, is at the top of the head of the radius. Anterior elbow osseous anatomy. The ends of the bones are covered with cartilage. It consists of three ‘joints’, which lie within one joint capsule and together have two separate functions. The trochlear surface of the humerus articulates with the trochlear notch of the ulna along an imaginary line A–A’ which runs slightly oblique (downwards and outwards) in its posterior course.

Lower: 1, annular ligament; 2, radial collateral ligament; 3, lateral ulnar collateral ligament. Morrey BF. This knowledge may, it is hoped, be translated into a broader understanding of the scientific basis of the management of elbow problems. This obliquity explains the physiological valgus position of the elbow in extension (Fig. The elbow joint articulation is classified as a trochoginglymoid joint. Extension is mainly limited by the olecranon abutting against the posterior aspect of the humerus in the olecranon fossa (Fig. It plays an important role in pronation–supination (see Gosling et al, Fig. Clinical examination of the sacroiliac joint 42. • The medial collateral ligament has an anterior part, which runs from the medial epicondyle of the humerus towards the annular ligament, a middle part towards the coronoid process, and a posterior part, directed towards the olecranon. Anatomy of the Elbow The elbow is a hinge joint made up of the humerus, ulna and radius.
