applied anatomy of elbow joint

They are both extracapsular. Abstract Knowledge of the anatomy and surgical approaches is crucial to develop a surgical strategy while minimizing complications. The elbow joint is a synovial joint found in the upper limb between the arm and the forearm. The ends of the bones are covered with cartilage. All three parts are reinforced by an oblique band (ligament of Cooper) distally on the ulna. They are both syndesmosis connections. 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 ulna: 1, trochlear notch; 2, coronoid process; 3, olecranon process; 4, radial notch; 5, ulnar tuberosity. Other ligamentous structures are: • The radial annular ligament, a U-shaped fibrous collar, covered with cartilage at its inner aspect, joins the radial head to the proximal ulnar extremity so that they can articulate. 3.93). Fig 3 Upper radioulnar joint. This knowledge may, it is hoped, be translated into a broader understanding of the scientific basis of the management of elbow problems. Dive into the research topics of 'Applied anatomy and biomechanics of the elbow joint.'. This overextension is the result of the format of the olecranon fossa and process. 315). 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. Interpretation of the clinical examination of the sacroiliac joint and coccyx 43. On humerus: 1, trochlea; 2, coronoid fossa; 3, medial epicondyl; 4, capitulum; 5, radial fossa; 6, capitulotrochlear sulcus. The ulna is also adducted (brought closer to the body) in supination and abducted in pronation. abstract = "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 elbow joint helps the hand to approach or move away from the body, whatever the arm position resulting from shoulder movement. Research output: Contribution to journal › Article › peer-review. Proximal to the capitulum lies the radial fossa and beside it a capitulotrochlear sulcus (between capitulum and trochlea).

It consists of three ‘joints’, which lie within one joint capsule and together have two separate functions. • The interosseous membrane (see Putz, Fig. 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. 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. 5). 307). Anatomy and title = "Applied anatomy and biomechanics of the elbow joint.". This knowledge may, it is hoped, be translated into a broader understanding of the scientific basis of the management of elbow problems.". The unique positioning and interaction of the bones in the joint allows for a small amount of rotation as well as hinge action. Fig 6 The range of flexion–extension movement. Figure 3-5 Posterior elbow osseous anatomy. Extension is mainly limited by the olecranon abutting against the posterior aspect of the humerus in the olecranon fossa (Fig. It is attached to the lower end of humerus in a continuous line, which excludes the two epicondyles but include three fossae. LIGAMENTS OF ELBOW JOINT  Capsular ligament  Ulnar collateral ligament or Medial ligament  Radial collateral ligament or Lateral ligament 9. The dotted line shows the insertion of the joint capsule. 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. 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. On radius: 6, circumference; 7, articular facet; 8, radial tuberosity. The articulation between the capitellum and upper surface of the head of the radius is, on the contrary, a ball-and-socket joint. This obliquity explains the physiological valgus position of the elbow in extension (Fig. 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. 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.

Wrist joint – applied anatomy November 27, 2011 admin Applied Anatomy 0 Dr Jyothi K BHMS, MD(Hom) Wrist joint This joint is also called radio-carpal 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. Clinical examination of the sacroiliac joint 42. 6) and by stretching of the anterior part of the joint capsule. Disorders of the sacroiliac joint 44. The arteries that contribute include: from the brachial artery The three joints work closely together and make pronation and supination movements possible whatever the extent of flexion or extension of the elbow: • The humeroulnar joint acts as a hinge. Applied anatomy and biomechanics of the elbow joint. The circumference of the head of the radius articulates with the radial notch of the ulna. On ulna: 3, olecranon process. The elbow-joint is a pure hinge- joint. These ligaments help to maintain the articular surfaces in contact with each other. It plays an important role in pronation–supination (see Gosling et al, Fig. publisher = "American Association of Orthopaedic Surgeons". The three ‘joints’ are the humeroulnar, the humeroradial and upper radioulnar joint (Figs 1–3, see Putz, Fig. Anatomy Sport-specific applied anatomy of the elbow joint complex can be broken down and divided into osseous, capsuloligamentous, musculotendinous, and neurologic components. Subcutaneous bursitis: Repeated friction and pressure on the bursa can cause it to become inflamed.  the annular ligament binds the head of the radius to the radial notch of the ulna forming the proximal radioulnar joint – this is a pivot joint allowing for pronation and supination 8. • 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. Cushions of extra-synovial fat fill up the three … Anatomy and biomechanics 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. Buy Membership for Orthopaedics Category to continue reading. Oblique line is A–A’ (see text). It prevents downwards movement of the radius. The other part of the joint is formed by the olecranon, with its trochlear notch and its olecranon (proximal) and coronoid (distal) processes. ONLINE Applied anatomy of the sacroiliac joint 41. The elbow is a seemingly simple joint. In its anterior course, the axis of movement is horizontal: therefore, in flexion, the forearm lies exactly in front of the upper arm. • 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. 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. The elbow joint helps the hand to approach or move away from the body, whatever the arm position resulting from shoulder movement. The capsule is reinforced by strong lateral ligaments (Fig. 329).—The anterior ligament is a broad and thin fibrous layer covering the anterior surface of the joint. Applied anatomy and biomechanics of the elbow joint. The radiohumeral and proximal radioulnar joint allows axial rotation or a pivoting (trochoid) type of motion. This rotation is easily noticed during activities such as hand-to-mouth eating motions. The functional anatomy of the elbow joint complex is unique in orientation and configuration. TY - JOUR T1 - Applied anatomy and biomechanics of the elbow joint. This facet exactly follows the shape of the humeral capitulum. The articulation between the trochlea and ulna is so shaped as to allow no lateral motion, but only an anteroposterior one. 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. It functions to allow blood to flow around the elbow joint no matter which position the joint is in. Fig 1 Humeroulnar and humeroradial joints (anterior view). By continuing you agree to the use of cookies. Morrey BF. Fig 2 Humeroulnar and humeroradial joints (posterior view). 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. • The quadrate ligament attaches the radial neck to the distal aspect of the radial notch of the ulna. FIBROUS CAPSULE Fibrous capsule completely envelop the 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. The dotted line shows the insertion of the joint capsule. Anatomy of the Elbow Joint The three bones that are responsible for the formation of the elbow joint are humerus , radius and ulna . Fig 5 The physiological valgus position. The periarticular arterial anastomosis of the elbow consists of several arteries that supply the elbow joint and its supporting structures. Articular surfaces: Elbow joint consists of two articulations. Anatomy of the Elbow The elbow is a hinge joint made up of the humerus, ulna and radius. The elbow is the visible joint between the upper and lower parts of the arm.It includes prominent landmarks such as the olecranon, the elbow pit, the lateral and medial epicondyles, and the elbow joint.The elbow joint is the synovial hinge joint between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the … 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. It is the point of articulation of three bones: the humerus of the arm and the radius and the ulna of the forearm. Studies on the elbow joint are now especially pertinent because of the increasing interest in congenital anomalies of the skeleton. Have you been making any of these common anatomy learning mistakes? Applied anatomy and biomechanics of the elbow joint. On radius: 9, radial head. Because this bursa lies relatively superficially, it can also become infected (e.g cut from a fall on the elbow) 4): Fig 4 The medial (upper) and radial (lower) collateral ligaments. The elbow joint helps the hand to approach or move away from the body, whatever the arm position resulting from shoulder movement. It consists of three ‘joints’, which lie within one joint capsule and together have two separate functions. It has the appearance of a plain hinge between 3 bones, the humerus above and the ulna and radius below (Fig. 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. This knowledge may, it is hoped, be translated into a broader understanding of the scientific basis of the management of elbow problems. Because it articulates with the capitulotrochlear sulcus at the ulnar side, it allows pronation–supination movements as well. LIGAMENTS OF ELBOW JOINT Capsular ligament Ulnar collateral ligament or Medial ligament Radial collateral ligament or Lateral ligament 10.
