| Question | Answer |
|---|---|
| tears that occur over the superior part of the labrum of the glenoid cavity, occurs both in front and back of attachment point of biceps brachii | SLAP lesion |
| what does SLAP stand for | superior labrum anterior and posterior lesions |
| in what muscles will you see a bulge with a SLAP lesion | bicep |
| detachment of anterior inferior labrum from underlying glenoid, humeral head falls posteriorly and rolls forward, involves tearing of the anteroinferior part of the labrum | Bankart lesion |
| if a Bankart lesion involves the glenoid margin what kind is it | boney |
| encompassing term used for the conditions of subacromial bursitis, rotator cuff tendinitis, supraspinatus tendinitis, painful arc syndrome, caused by a consistent "throwing" motion, acromial head displaced anteriorly, area becomes inflamed | impingement syndrome |
| adhesive capsulitis, thickening of joint capsule, supraspinatus tendon will become scarred and bursa will become calcified which results in a lack of movement | frozen shoulder |
| common in kids under 4, caused by a sudden pull on the extended pronated arm can lead to subluxation of radial head from annular lig., pronated radial head slips partially under annular lig. and displaces into radiocapitellar joint | pulled (nursemaid's) elbow |
| treated by firmly supinating the forearm and flexing the elbow while pressing down on the radial head | pulled (nursemaid's) elbow |
| compression of ulnar n. between humeral and ulnar heads of flexor carpi ulnaris m., can palpate, causes tingling, impacts everything distal to the compression | cubital tunnel syndrome |
| compression of median n. between humeral and ulnar heads of pronator teres m., caused by pronator teres m. becoming inflamed, causes m. atrophy and tingling of fingers or forearm | pronator syndrome |
| caused by pinching/impinging on the radial n. in the axillary region, everything below it will be impacted, causes motor and sensory loss | crutch palsy |
| loss of digit extension at MCP joints, weak digit extension at IP joints, weak wrist adduction, wrist drop, weak forearm supination, loss of elbow extension | motor loss from crutch palsy |
| dorsal skin of lat. 3 1/2 digits, lower lateral and posterior arms, and posterior forearm | sensory loss from crutch palsy |
| causes triceps to be weakened but not paralyzed; wrist drop; sensory loss of posterior forearm, lower lateral arm, and dorsal skin of lat. 1/3 digits; weak elbow extension; weak forearm supination; muscles in forearm are paralyzed/begin to atrophy | symptoms of saturday night palsy |
| named for radial n. being impinged around shaft of humerus, usually caused by a break in that location, radial n. and deep brachial a. at risk (triangular interval) | saturday night palsy |
| motor: loss of digit extension at MCP joints, weak digit extension at IP joints, weak wrist adduction, wrist drop, weak forearm supination sensory: dorsal skin of lateral 3 1/2 digits | radial tunnel syndrome |
| test by putting two fingers on the radial n. at elbow joint and trying to flex the wrist posteriorly | radial tunnel syndrome |
| compression of deep motor branch of radial n. between the superficial and deep strata of supinator m., supinator m. compresses PIN | supinator syndrome |
| motor: loss of digit extension at MCP joints, weak digit extension at IP joints, weak wrist extension and adduction sensory: some lost and some remain because of superficial radial n. | supinator syndrome |
| motor: loss of digit extension at MCP joints, weak digit extension at IP joints, weak wrist extension and adduction sensory: some in forearm (little) | PIN palsy |
| median n. is compressed by flexor retinaculum; causes tingling and atrophy of forearm muscles | carpal tunnel syndrome |
| effects depend on location of lesion (more prox. = more affected, more dist. = less effected), mostly flexion lost | injury to n. |
| also known as hand of Benediction | injury to median n. |
| flexion of prox. IP joints of 1-3 digits is lost, flexion of dist. IP joints of 2nd and 3rd digits is lost, extensor compartment will be unopposed and extend back, flexion of 4th and 5th digits is weakened | median n. lesion at elbow |
| flexor carpi ulnaris m., hypothenar mm., 3rd and 4th lumbricals, interosseous mm., adduction, abduction, flexion of distal IP joints of 4th and 5th digits due to FDP and lumbricals remain after a lesion to what nerve | median n. |
| causes hyperextension at MCP joints, weakened extension at DIP joints, and unopposed flexion at PIP joints, unopposed action of extensors and FDP, wrist adduction impaired; mostly affects intrinsic mm., loss of flexion at IP joints of 4th and 5th digits | injury to ulnar n. |
| also known as claw hand | injury to ulnar n. |
| entrapment of superficial branch of the radial n. with sensory deficits | Wartenberg's syndrome |
| also known as cheiralgia paresthetica | Wartenberg's syndrome |
| common fracture, dist. fragment of radial n. is usually displaced dorsally, produces a "fork" deformity | Colles' fracture |
| common carpal fracture, prox. segment of this bone undergoes reduced/restricted blood flow before dist. component | scaphoid fracture |
| herniated disc that affects spinal nerves | posterolateral |
| herniated disc that affects spinal cord and everything below it | central |
| which region of the spinal cord are herniated discs more complicated | lumbosacral |
| usually happens when you fall on your shoulder, has 2 types | dislocation of acromioclavicular joint |
| types: dislocation of AC joint without ligament tear, dislocation of AC joint with ligament rupture | dislocation of acromioclavicular joint |
| if piriformis m. becomes inflamed it will press on what n. and causes pain and sensory issues, numbness, and atrophy of lower leg | sciatic n. |
| when standing on an unaffected limb, foot drop, walking with a waddling gait, leg will be thrown/swung out while walking | trendelenberg's syndrome |
| caused by an issue with the long thoracic n., tested by having someone push on a wall | winging of scapula |
| cervical and/or lumbar curvature | lordosis |
| thoracic and/or sacral curvature | kyphosis |
| osteoarthritis of the intervertebral joint | spondylosis |
| stress fracture of pars interarticularis | spondylolysis |
| anterior displacement of a vertebrae | spondylolisthesis |
| excessive axial loading (ex. diving into shallow water), forces lateral masses apart, damage to spinal cord, uncommon | Jefferson's (burst) fracture |
| traumatic spondylolysis of C2, associated with spinal cord injury, results from hyperextension | hangman's fracture |
| tested by pulling lower leg forward when bent, relates to anterior cruciate ligament | anterior drawer sign |
| tested by pushing lower leg backward when bent, relates to posterior cruciate ligament | posterior drawer sign |
| what is harmed when a foot is planted and fixed, the leg rotates, and there's an impact to the body | unhappy triad |
