UPPER LIMB PATHOLOGY - RAPID ASSESSMENT Murali Bhat www.ukorthocare.com BASIC ANATOMY • Root- between scalenus anterior & scalenus posterior muscles with Subclavian artery • Inferior part of neckroots unite trunks • Trunks – superior, middle, inferior • Each trunk divides into anterior & posterior division • Division form 3 cords • Cords – names indicated by relationship with Median Nerve PRONATER TERES PRONATER TERES ANTERIOR INTEROSSEOUS NERVE FDS Ulnar Nerve MEDIAN NERVE ULNAR NERVE SYMPTOMS 1. Pain 2. Loss of function 3. Cosmesis Examination • Look • Move • Feel (Special tests) Surface anatomy Palmar Surface Anatomy Pain • Localised Wrist • Generalised hand and arm B.Movements Passive movements -extension B.Movements • Passive movements -flexion PALPATION Dorsal Palpation & Special Test Palpation & Special Test • Scaphoid • -the waist in the anatomical snuffbox • -painful non union can be tested by the grinding test • Axial pressure along 1st metacarpal with wrist in radial deviation • -crepitus can be felt in OA of the CMC joint or scaphoid non union Surface anatomy LISTER’S TUBERCLE Dorsal Surface anatomy SCAPHOLUNATE LIGAMENT Dorsal B.Movements • Active movement -pronation B.Movements • Active movement • -supination Surface anatomy Ulnar head Dorsal Surface anatomy Ulnar styloid Dorsal Palpation & Special Test • TFCC • Clamp both radius & ulna • The other hand applies axial loading in ulnar deviation • Carpus is pronated & supinated • TFCC is assessed for pain and clicking Examination of DRUJ Palpation & Special Test • FCU & Pisiform bone • -feel the tendon and pisiform bone with the tip of the index finger Palpation & Special Test • Piso-triquetral joint • -by applying gentle thumb pressure on the pisiform towards the midline • -FCU tendon,push against resisted flexion and ulnar deviation Palpation & Special Test • Hook of hamate • -can be tender in non union • -place thumb on pisiform and move distally 1-2 cm and • -radially along a line joining the pisiform to the neck of the 2nd metacarpal • -simultaneous pressure is applied on the dorsal and ulnar aspect of this bone with the index & middle finger Diffuse Arm Pain Cross section through carpal tunnel • Roof is formed by the tranverse carpal ligament • Floor and wall formed by the carpal bones Surface anatomy Palmar Thoracic Outlet Syndrome – Five clinical syndromes • • • • • Major arterial syndrome Minor arterial syndrome Venous obstruction syndrome True neurogenic thoracic outlet syndrome Disputed neurogenic thoracic outlet syndrome – Generally: pain, weakness, numbness and tingling, swelling, fatigue or coldness in the arm and hand Neurological Disturbance • Usually in C8 andT1 distribution but may also involve entire hand • if numbness extend to ulnar border of forearm or upper arm, increased likelihood of thoracic outlet or root aetiology (since these are medial cutaneous nerves of forearm and arm territories, not ulnar nerve) Loss of Function • Deformity • Instability COSMESIS • Swelling • Deformity COMMON SWELLINGS Elbow examination Look • Muscle wasting • Swelling or effusion • Deformity e.g. cubitus varus /valgus Carrying angle of the elbow • Males:2-22 deg • Females :2-26 deg Feel •Relationship and Tenderness over both epicondyles and olecranon process ,radial head •Tenderness over ulnar nerve region Palpation of ulnar nerve Relationship between both epicondyles & olecranon process • • • • 3 bony landmarks Medial epicondyle Lateral epicomndyle Olecranon process • Equilateral triangle in flexion • Straight line in extension Move • • • • Extension/hyperextension Flexion –screening /actual measurement Pronation-screening/actual measurement Supination-screening/actual measurement Flexion & Extension Pronation & Supination
