Physical examination should focus on muscles innervated by the ulnar nerve distal to the cubital tunnel: the flexor carpi ulnaris, the flexor digitorum palmaris, the hypothenar eminence, and the intrinsic muscles of the hand. acts as a lever arm when positioning the hand, 40% of weight is through ulnohumeral joint, 60% of weight is through radiohumeral joint, the shaft for humerus has a spiral groove posteriorly (contains radial nerve), this lies approximately 13 cm proximal to the articular surface of trochlea, the distal flare of humerus includes the medial and lateral epicondyles, the flare accounts for half of the elbow joint, the sublime tubercle on the ulna is where the anterior bundle of the medial ulnar collateral ligament attaches distally, distal humerus contains medial and lateral column, the joint surface is anteriorly tilted approximately, it passes through anteroinferior medial epicondyle, radial head is covered by cartilage for approximately 240 degrees, the lateral 120 degrees contains no cartilage, this is crucial for internal fixation of radial head fractures, coronoid fossa on distal humerus receives the coronoid tip in deeper flexion, the coronoid tip has a buttress effect in the prevention of posterior dislocations, distal attachment of anterior capsule is found 6 mm distal to tip of coronoid, the distal biceps attachment is at the level of the radial tuberosity, the attachment of the brachialis 11 mm distal to the tip of the coronoid, loss of 50% or more of coronoid height results in elbow instability, the MCL is composed of the anterior, posterior and transverse bundles, the MCL provides resistance to valgus and distractive stresses, anteroinferior aspect of medial epicondyle, sublime tubercle of medial coronoid process, most important restraint against valgus stresses, the posterior bundle forms the floor of the cubital tunnel, primary restraint to valgus stress in maximal elbow flexion, if this is contracted, flexion may be limited, lateral collateral ligament complex (LCL), primary restraint to varus and external stress during full arc of elbow motion, some believe that the the accessory collateral ligament and the radial collateral ligament contribute substantially to lateral elbow stability, provides stability to the proximal radioulnar joint, the LCL arises from isometric point on lateral aspect of capitellum, optimal stability is conferred with an appropriately tensioned LCL repair, this functions as an important constraint to valgus stress, the radial head provides approximately 30% of valgus stability, this is most important at 0-30 deg of flexion/pronation, greatest contribution the capsule on stability occurs with the elbow extended, origins of the flexor and extensor tendons, it exits laterally, distal to the biceps tendon, it will terminate as the LABC (forearm), which is found deep to the cephalic vein, it leaves the triangular interval (teres major, long head of triceps and humeral shaft), found in spiral groove 13 cm above the trochlea, pierces lateral intermuscular septum 7.5 cm above the trochlea, this is usually at the junction of the middle and distal third of the humerus, lies between the brachialis and the brachioradialis, distally it is located superficial to the joint capsule, at the level of the radiocapitellar joint, medial/lateral cords of the brachial plexus, it courses with brachial artery, running from lateral to medial, lies superficial to brachialis muscle at level of elbow joint, runs medial to brachial artery, pierces medial intermuscular septum (at the level of the arcade of Struthers) and enters posterior compartment, it traverses posterior to the medial epicondyle through the cubital tunnel, first motor branch to FCU is found distal to the elbow joint, contents-- biceps tendon (lateral), brachial artery, median nerve (medial), at the level of elbow it splits into the radial and ulnar arteries, the axis of rotation is found at the center of trochlea, pronation (pronator teres and quadratus) & supination (biceps and supinator), the axis of motion is found at the capitellum through to the radial/ulnar heads, there are large joint reaction forces due to short and inefficient lever arms around elbow (biceps inserts not far from center of rotation), this contributes to degenerative changes of the elbow, is a line through isometric points on the capitellum about trochlea, the axis of pronation / supination is a line drawn from capitellum, through radial head, to distal ulna, Free body diagram demonstrate inefficiencies of elbow, Dynamic loads are greater than body weight, one elbow in 110 of flexion for feeding, one elbow in 65 of flexion for perineal hygiene, Intra-articular injection best given in
