1 " forearm posterior compartment " compartments of the forearm Posterior Fascial compartment Muscles: ** The superficial group 1. Extensor carpi radialis brevis 2. Ex. digitorum 3. Ex. digiti minimi 4. Ex. carpi ulnaris 5. anconeus ** The deep group 1.supinator 2.Abductor pollicis longus 3.Ex. pollicis brevis 4.Ex. pollicis longus 5.Ex. indicis Blood supply: Posterior & anterior interosseous arteries Lateral Fascial compartment In some books it regarded as part of Posterior compartment Muscles: 1.Brachioradialis 2.extensor carpi radialis longus 1. Blood supply: branches of the radial and brachial arteries Nerve supply: Radial nerve Anterior fascial compartment Nerve supply: Deep branch of the radial nerve (posterior interosseous nerve). 1

2 * Muscles of the Lateral Compartment of the Forearm : 1. Brachioradialis : --Origin : Lateral supracondylar ridge of humerus Upper two thirds --Insertion : Base of styloid process of radius -- Action : 1. rotates forearm to the midprone position 2. flexes forearm at elbow joint, because it crossing the elbow joint ( عضلة الكاراتيه ) muscle * So it named as karate 2. Extensor carpi radialis longus --Origin : lower third of lateral supracondylar ridge of humerus ( below the oridin of Brachioradialis ) -- Insertion : dorsal surface of base of second metacarpal bone -- Action : Extends abducts wrist في الطب كلمة وحدة بتفرق!! الزم تحدد Ant or Post Flexor Extensor Insertion Palmar surface " anterior " of the base of metacarpal bones Dorsal surface " posterior " of the base of metacarpal bones ** Both muscles have common structures: 1. Origin : Lateral supracondylar ridge of humerus 2. Blood supply : branches of the radial and brachial arteries. ( brachial artery cross from medial to lateral in the spiral groove with the median nerve, then the branches give the ant & pos branches which give the B.S to the muscles ). 3. Nerve supply : Radial nerve before it divides into superficial and deep branches (Radial nerve also give the lateral half of brachialis " has double nerve supply " ). *Suggested Question * All of the following muscles have double ( dual ) innervation Except : a. Brachialis ( Musculocutaneous, radial nerves ) 2

3 b. Deltoid ( Axillary nerve ) c. Pectoralis major ( Lateral, medial Pectoral nerves ) d. Flexor digitorum profundus ( Anterior interosseous, ulnar ) e. Subscapularis ( Upper, Lower Subscapular nerves ) أما بالنسبة لل " value " Root نحن مطالبين فقط بمعرفتها لل : Main nerves Median, ulnar, Axillary, Radial nerves ****Radial nerve : Its branch from the posterior cord of brachial plexus, in the arm it passing in the spiral groove with profunda brachii artery. it piercing the lateral intermuscular septum above the lateral epicondyle it give superficial and deep branches in the cubital fossa " the most lateral structures ". * * Deep branch of radial nerve (Posterior interosseous nerve) : 1. descends in the downward in Post Comp between the superficial and deep muscles. 2. pierces the Supinator muscle 3. then it winds around the neck of the radius ( weak point " if there is injury in the neck then the injury will happen for the the deep branch and occur finger drop only,, because deep branch give the pos compartment muscles # except anconeus # which extend the fingers). # In comparison with Radial nerve injury it'll occur complete hand drop including the fingers It eventually reaches the posterior surface of the wrist joint. Branches : 1. Muscular branches 2. Articular branches to the wrist and carpal joints 3

4 A B E Anconeus Brachioradialis Extensor carpi radialis longus * Superficial Branch of the radial Nerve( anterior interosseous nerve ) : it passes through the anterior compartment under the cover of the brachioradialis, in the insertion of brachioradialis it passes deep to the tendon and runs in the lateral two thirds of the posterior surface of the hand and skin over the proximal phalanges for lateral three and a half fingers. " in the roof of snuff box " # Snuff box -Floor : scaphoid "common side of fracture" and trapezium crapal bones -Anteriorly: *abductor pollicis longus & ex. pollicis brevis -Posteriorly : *extensor pollicis longus. -Roof : superficial branch of radail nerve -Content :radial artery "knowing the pulsation " Contents of the Pos. Fascial Compartment of the Forearm # Musles ** The superficial group 1. Ex. carpi radialis brevis O:Lateral epicondyle of humerus. " common origin " I: Dorsal surfaces of base of 3rd metacarpal. Lies deep to extensor carpi radialis longus. A:Extends and abducts wrist. NS: Posterior interosseous nerve. 2. Ex. digitorum O: Lateral epicondyle of humerus I: Base of dorsal surfaces of middle and distal phalanges. 4

5 -- Forms four tendons, each passes into a finger, so they run dorsally in the dorsum of the finger where is the extensor fibrous expansion "dorsal digital expansion" ( fibrous tissue for the insertion of the tendon,, It has 3 slips : *. one middle :attaches with middle phalanx *. two lateral : attach with the base of distal phalanx There job : fix the tendon of dorsal digital expansion A:Extends all joints of hand and fingers # there is Connection between the tendon of Ex. digitorum & Ex. digiti minimi called :" fibrous connection " 3. Ex. digiti minimi O: Lateral epicondyle of humerus I: Dorsal digital expansion of little finger along with the tendon of extensor digitorum. A:Extends MCP &IP joints of little finger Little finger has 1 tendon and connect with other tendon 4. Ex. carpi ulnaris O: Lateral epicondyle of the humerus I: base dorsal surface ( base of 5th metacarpal ) A: Extends and adducts the wrist NS: Posterior interosseous nerve. # flexor.corpi ulnaris ( NS): ulnar nerve 5. anconeus Small muscle behind the elbow joint. O: lateral epicondyle of humerus. I: Post surface &Lat aspect of Olecranon process, post surface of ulna. A: Weak extensor of elbow NS: Radial Nerve 5

6 ** The deep group 1.supinator "V. important " Two heads O: Superficial head: * lat epicondyle of humerus, * radial collateral lig of elbow( lig in elbow joint in the lateral side between humerus and radius ) * annular lig( lig surrounding the head of radius ) Deep head : supinator crest of ulna,post part of triangular area in front of it ( ulna ) I: neck and upper part of the shaft of radius A: Supination + extension of the forearm and hand # But the biceps: supination + flexion " screwing muscle " NS: Posterior interroseous nerve. ** Muscles which pass to the thumb : 2.Abd pollicis longus " ant boundary of snuff box " O: post surfaces of the radius & ulna & interosseous memb. I: - Radial side of base of 1st metacarpal.

NS: Posterior interosseous nerve ** Index has 2 separate tendons and no connection with other tendons. ( see fig 2 ) # The most important function of the hand : Opponent (done by the thumb " counting against the other fingers", writing position ( flexion at the metacarpophalangeal joint and extension in interphalangeal joint and medial rotation ) Arteries of the Post Fascial Compartment of the Forearm The anterior and posterior interosseous arteries arise from the common interosseous artery, a branch of the ulnar artery They pass downward on the anterior and posterior surfaces of the interosseous membrane, respectively, and supply the adjoining muscles ( Blood supply ) and bones. (Nutrient artery) ** They end by taking part in the anastomosis around the wrist joint. ( 6 arteries ) -Ant & post interosseous artery -Ant & post carpal of brachial artery -Ant & post carpal of ulnar artery The radial artery reaches the back of the hand by passing between the lateral collateral ligament of the wrist joint 7

8 and the tendons of the abductor pollicis longus and extensor pollicis brevis " floor of the snuff box " # Extensor Retinaculum Fibrous sheath of deep fascia attached: ^ medially with styloid process of ulna & pisiform bone & the hook of the hamate. ^laterally with lower part of radius its a thickening of deep fascia that stretches across the back of the wrist and holds the long extensor tendons in position. converts the grooves on the posterior surface of the distal ends of the radius and ulna into six separate tunnels for the passage of the long extensor tendons Each tunnel is lined by a synovial sheath (fibrous sheath has afluid to make lubrication around the tendon before and after Ex. Retinaculum ), which extends above and below the retinaculum on the tendons The tunnels are separated from one another by fibrous septa that pass from the deep surface of the retinaculum to the bones The upper and lower borders of the retinaculum are continuous with the deep fascia of the forearm and hand, respectively # Carpal Tunnel Tunnel deep of Ex. retinaculum spically for the median nerve, it names as median nerve tunnel. It found under flexor retinaculum. The median nerve lies between the tendons of the flexor digitorum superficialis and the flexor carpi radialis muscles 8
