Type:-
Hinge variety of synovial joint
Location:
between lower end of humerus upper ends of radius & ulna
4
Upper: capitulum & trochlea of humerus
• Lower : upper surface of head of radius: capitulum trochlear
notch of ulna: trochlea.
Note: continues with superior radioulnar joint.
5
Collaboration of…
Humeroradial
Humeroulnar
Superior radioulnar
(collaboration means the action of working with someone to produce somthing)
(the elbow joint is a synovial joint found in the upper limb between the arm and the
forearm. It is the point of articulation of three bone : humerus of the arm and the
radius and the ulna of forearm.)
6
Capsular ligament(joint capsule)
Ulnar collateral ligament
Radial collateral/ lateral ligament
7
Attechment:-
Above:
Medial epicondyle,upper margin of
radius,coronoid and olecranon fossa and
lateral epicondyle of humerus.
Below:
- Anterior and medial margin of coronoid
process of ulna.
- Upper margin of annular ligament.
- Upper and medial margin of olecranon
process.
8
Also khowns as medial ligament
shape: Triangular ligament
Apex: medial epicondyle of humerus
Base: ulna
Parts:
Anterior band
Posterior band
Oblique band
NOTE:- Crossed by ulnar nerve
Origin : flexor digitorum superficialis
9
Also khowns as lateral
ligament
• Fan shaped
• Extension:
lateral epicondyle to annular
ligament
10
• Anteriorly: brachialis, median nerve, brachial artery, biceps
tendon
• Posteriorly: triceps & anconeus
• Medially: ulnar nerve, flexor carpi ulnaris, common flexors
• Laterally: supinator, extensor carpi radialis brevis, common
extensors
11
Subtendinous olecranon bursa:
Small bursa between triceps tendon and upper surface of olecranon
process.
Subcutaneous olecranon bursa :
large bursa between skin and subcutaneous triangle area on the
posterior surface of olecranon.
Bicipitoradial bursa:
Small bursa seperating biceps tendon from smooth anterior part of
radial tuberosity.
12
Pully-shape trochlea
of humerus fits
properly into jaw
like trochlear notch
of ulna.
Strong ulnar and
radial collateral
ligament.
13
Arterial anastomosis around
the elbow formed by branches
of brachial,radial and ulnar
arteries.
14
Articular branches from
1) radial nerve
2) muskulocutaneous nerve
3) ulnar nerve
4) median nerve
15
Flexion:
brachialis, biceps, brachioradialis
Extension:
triceps, anconeus
Supination and pronation are rotatory movement of forearm which occur at superior radio-
ulnar joint.
supinator muscle .
Brachioradialis supinator the pronated forearm to midprone position.
Pronator teres
Pronator quadratus
16
17
Carrying AngleThe transverse axis of elbow joint is oblique
being directed downwards and medially
The angle of deviation of long axis of forearm from long axis
of arm is termed as carrying angle.
Carrying angle disappears during pronation and full flexion of
forearm.

Subluxation of elbow
Tennis elbow
Miner’s (or student elbow)
Elbow tunnel syndrom
Bicipitoradial bursatis
