MSK Exam Notes
Document Sample


MSK CCC 1: DDX of Cervical Pain
Cervical Radiculopathy – direct irritation of cervical nerve root from:
Osteophyte, space occupying lesion, increased stress or tension in foraminal area
S/S: Arm pain
Clumsiness
Pain in Trapezius, Paraspinal, Interscpular muscles
Dermatomal paresthesias or hypesthesia
Cervical Spondylosis – various degenerative diseases of spine, ankylosis of adjacent vertebral bodies,
degeneration of intervertebral disc from:
Age related degeneration, trauma or genetics
S/S: Decreased ROM
Pain in paracervical, trapezius, interscapular muscles
Pain with upward gaze or rotation of neck, extension of neck
Progression leads to:
Dehydration of the disc, thinning of disc space, protrusion of disc
Buckling/dysfunction of intralaminar ligaments
Abnormal loading and fxn of joint surface
Compensatory Changes (ex. Osteophytes)
PE: Spasm of cervical m. knotty or firous texture of muscles
Loss of normal cervical lordosis
Somatic dysfunction
Cervical Degenerative Joint Disease – degenerative/hypertrophic changes in bone/cartilage of 1+ joints
with progressive wearing down of opposing joint surfaces => distortion of joint position

Somatic Dysfunction Cervical Spondylosis/DJD
Cervical Radiculopathy Visceral Referred Pain
Mechanical Referred pain Pathologic Fracture
Infection
Diagnosis:
X-rays: AP/lat/oblique views Myelogram

Treatment approach for cervical pain
OMT, PT, Cervical traction, Medications, Surgical referral
Cervical Dermatomes/Muscle Groups
C5 – elbow flexors
C6 = wrist extensors
C7 – elbow extensors
C8 - finger flexors
T1 – small finger abductors
Hints for PE:
If during gross motion testing, the head automatically sidebends and rotates in opposite
directions, think OA &/or Sternocleidomastoid (SCM).
If during gross motion testing, the head automatically sidebends and rotates in same direction,
think single SDs (perhaps a few of them).
If restriction in flexion, think trapezius; restriction in extension SCM & strap muscles (muscles
that connect to the hyoid).
If dysphagia (sensation of swallowing difficulties), think strap muscles and hyoid.
If radiation of pain to upper extremities, think entrapment (spondylosis, scalenes, first rib
dysfunction, herniated disc).
If radiation of pain to occiput - many muscles, occipital nerves.
If headache with pressure and tight headband sensation, think suboccipital and occipitalis
muscles and greater & lesser cranial nerves.
Any kind of symptom, think somatic dysfunction.
If dizziness or syncope, especially on head turning, think compromise of carotids &/or vertebral
arteries. Be Careful
In cases of respiratory disease, think scalenes & sternocleidomastoid (secondary muscles of
respiration) and C3,C4, & C5 (attachment of scalenes and origin of phrenic nerves)
If radiation of pain to the ear or jaw, think SCM and stylohyoid
MSK CCC 2: Imaging of spine
Why imagine the spine?
trauma, pain, disturbance in sensation/movement, neoplastic disease workup
Techniques:
Plain radiographs
Cervical: AP, lat, obliques, open mouth (c1-c2), swimmer’s (c7)
Assess lines on lateral (anterior, posterior, spinolaminar, posterior spinous)
Thoracic: AP, lat
Lumbar: AP, lat, obliques, lateral sacrum
Sacrum/coccyx: AP, lat, obliques for SI joints
CT + CT thin section - Better for bony structures
Needed for many thoracic cases because of superimposed structures seen on xray
Lumbar – disc or bone abnormality
MRI - Better soft tissue structures: cord, ligaments, discks, marrow
Cervical – axial + sagittal + coronal without contrast
Thoracic – not good due to pulsating structures
Lumar – cord, disc abnormalities, bone contusion, ligamentous injury
Bone scan – look for multiple areas of involvement or unsuspected lesions
Traumatic lesions – most from blunt trauma
Indications for imaging: pain, neurologic deficit, distracting injuries, altered consciousness, high
risk MOI, vascular injury
Initial screen = plain films, then follow up with a spiral CT
Compression fracture – in thoracic/lumbar spine
Jefferson Fracture – in bony ring of C1
Dens fractures (Type I, II, and III)
Flexion teardrop fracture
Burst fracture – of C3-C7 from axial compression injury, common to injure cord due to posterior
displacement of fragments

>50% compression of vertebral body
>20° of kyphosis Interpediculate widening
>2 mm of translation Dislocation

Questions to ask in a possible tumor:
Age – certain tumors for certain age groups
Duration of complaint
Rate of growth
Pain associated with the mass – B9 are not painful
History of trauma
Personal/family hx of cancer
Systemic signs or symptoms
Tumors are named by tissue origin and location within the bone:
Know: Tumors that recur and tumors that can become BAD
Osteochondroma from bone and cartilage “harmatomas”
MC B9 bone tumor that arise near the ends of long bones
10-20 years of age
Secondary malignant chondrosarcoma arises in 10%
X-ray shows bony outgrowth from cortex (most of tumor is in cartilage cap so opacity on xray is
smaller than the mass feels clinically)
Tx: Necessary if tumor is near a nerve, causes pain (fxs), disturbs growth or becomes malig
Hereditary multiple osteochondromatosis
AD inheritance, lots and lots of tumors
Risk for chondrosarcoma development is higher
Fibrous Dysplasia – defect in osteoblastic differentiation and maturation
Any bone can be affected with medullary bone replaced by fibrous tissue
Appears “ground-glass” on xray
CT scan can show expansion of the bone due to intramedullary expanding lesion
*Monostotic is 7-10x times more common than polyostotic
Associated with systemic conditions (precocious puberty/McCune-Albright/myxomas)
Tx: conservative primarily to prevent deformity
Surgical indications: severe/progressive, nonunion, painful, fx
Chondroma – uncommon B9 tumor within bone marrow that forms mature cartilage
Men in 2-4th decade, asymptomatic – found incidentally as lytic lesions with stippled calcification
when x-rays are taken for something else
~small bones of hand/feet usually
~can be mistaken for chondrosarcoma
Tx: asymptomatic requires no tx, but need to rule out progressive
Non-ossifying fibroma – nonneoplastic, asymptomatic
Usually found in children with 75% occurring in the 2nd decade
Femur > Tibia at juxtaepiphyseal region
Larger lesions presents as a pathologic fracture
Xrays show lesion migrating away from epiphyseal plate with time
Normally regress spontaneously – treat only if it has a pathologic fx
Chondroblastoma “Codman’s tumor”
Rare B9 tumor originating from cartilage
See pain wherever the tumor is, especially at ends of long bones
People age 10-20 years
X-ray: cyst containing spots of calcification that must be excised
Tx: sx, bone graft, PT – tumor may recur
Chondromyxofibroma
Rare, occurs before age 30
Located near end of long bones
Xray: lytic lesion with well defined margins in the metaphysic of leg
Radiolucent area is a giveaway
Tx: excision or curettage
Osteoid osteoma – MC benign osteoid-forming tumor
Primarily seen in long bones (proximal femur), classically causes pain at night in young adults
Xrays: new bone formation with sometimes a lucent spot
Tx: NSAIDs for pain

Risk factors: low calcium, smoking, alcoholism, meds
Age Women Men
Puberty to mid-20s & 30s Bone mass increases rapidly, reaching peak bone mass
Mid-30s to 40s A few years of stability, then slow bone loss No risk factors
bone loss 1% / yr
Mid-40s to 50s Menopause w/o estrogen replacement, then rapid
bone loss 7% / yr for With risk factors (smokers, i
7 yrs bone loss 6% / yr
Mid-50s to late life Continuing bone loss of 1% to 2% / yr
Epidemiology of Osteoporosis Fractures:
High prevalence
1.25 million female & 500,000 male hip fractures worldwide (1990)

Causes of Osteoporosis:
*Estrogen deficiency
Calcium deficiency & secondary hyperparathyroidism
Androgen deficiency
Changes in bone formation (getting older)
Secondary causes/meds (steroids, diuretics, heparin, etc.)

Vitamin D: 400-800 IUday regardless of sunlight exposure
Estrogen replacement: worried about side effects (PMS-like syndrome), risk of
endometrial/breast cancer
Big difference between natural and equine estrogen.
Bisphosphonates: stops the resorption of bone
Bad dentition! Do not give! Can cause osteonecrosis of the jaw!
Selective Estrogen receptor modulators
Prevent osteoporosis
Antagonists in breast/uterine tissue = less risk of cancer development
Calcitonin: hormonal inhibitor of bone resorption
Osteoarthritis/Degenerative Joint disease = MC type of arthritis
Layer of cartilage breaks down and wears away
Degree of abnormality on x-ray and clinical findings/symptoms do not always correlate
Spinal – intervertebral disks, vertebral bodies, posterior apophyseal joints
Nerve root compression = radicular pain
Degenerative changes:
Apophyseal joint
Spondylosis – degenerative DISK disease
Spondylolysis – classic OA change!

Morning stiffness for minutes vs hours in RA
Degree of pain > physical findings
Tenosynovitis: epicondylitis, rotator cuff tendinitis, Achilles tendinitis, posterior tibial tendinitis,
plantar fasciitis
Diagnosis:
No single diagnostic marker
Lupus presents with one or several of the following:
Unexplained nonspecific symptoms such as fever, fatigue, wt loss, or anemia
Photosensitive rash
Arthralgia, arthritis
Raynaud phenomenon
Serositis
Nephritis or nephritic syndrome
Neurologic symptoms (seizures or psychosis)
Alopecia
Phelbitis
Frequent miscarriages
Laboratory testing:
CBC, creatinine, albumin, ESR, CRP, UA, 24 hour urine
ANA (negative makes it unlikely – good for ruling out, not for positive diagnostic)
Antiphospholipid antibodies for hypercoagulability
*Anti dSDNA
*Anti Smith Abs
*+ abs confirm a diagnosis of SLE
Treatment:
1st line for pain + inflammation – NSAIDs or acetaminophen
Contraindicated in lupus nephritis (also COX-2)
Inflammation as prominent feature = NSAIDs (ibuprofen, naproxen, nabumetone)
Use with PPI if at risk for NSAID-induced GI toxicity
Pain without inflammation = Acetaminophen
Contraindicated in liver disease/alcoholism
Hydroxychloroquine (antimalarial) – for joint symptom relief, prevention of clinical relapse
For articular manifestations, rashes, and fatigue
Corticosteroids – used infrequently, only for inflammation – not pain
Risk of developing osteoporosis
Goal – use for acute flare-ups but get dose reduced as quickly as possible
Anakinra – IL1 receptor antagonist – for severe arthritis patients unresponsive to other rxs
Methotrexate – resistant inflammatory arthritis
Methotrexate + prednisone = more effective than pred alone
Amitriptyline – TCADs – when pain is unresponsive to other measures
Rheumatoid Arthritis – chronic systemic inflammatory disorder of unknown origin
*Causes inflammation of synovium causing chemicals to be released to thicken the
synovium/damage the cartilage/bone or affected joint inflammation pain + swelling
Clinical findings: Polyarticular, symmetrical, joints/tendons involved with destruction + synovitis

ORIF (test question – indications)
Indications: Displaced GT fx > 5mm, fx that involves articular surface, surgical neck fx, displaced
anatomical neck in young pt, displaced 3-/4- part fractures
Hemiarthroplasty - best for elderly, head splits, AVN
Indications – young/middle age with severe head split or extruded anatomic neck OR elderly
Technique – beach chair position with deltopectoral approach, retain tuberosity fragments,
bone graft from head if necessary
Ends up with unpredictable results from a functional standpoint
Complications of proximal humerus fracture
Avascular necrosis – due to disrupted arcuate artery
Adhesive Capsulitis – almost always develops, minimized by early motion and controlled PT
May be fixed with arthroscopic release
Acromioclavicular Joint Injuries
Anatomy
Clavicle – S shaped bone
SC joint, AC joint, CC ligaments with muscles attached : SCM, trap, pec major
AC joint – between acromion and lateral clavicle stabilized on all sides by ligaments (superior AC
most important)
CC ligs – at distal clavicle (suspend Upper extremity)
Trapezoid + conoid = stronger than AC, provide vertical stability to AC joint
MOI for AC joints
Moderate/high-energy traumatic impacts to the shoulder
PE:
Neurovascular exam (cervical roots)
UE motor/sensation + Shoulder ROM
Radiographic Evaluation:
AP, Zanca (orthogonal view)

Type II – vertical displacement, with joint disrupted
Type III - AC joint dislocated and the shoulder complex displaced inferiorly
Type IV - AC joint dislocated and clavicle displaced posteriorly into or through the trapezius
muscle, seen on axillary view
Type V - AC joint dislocated and gross disparity between the clavicle and the scapula (100-300%)
Type VI - AC joint dislocated and clavicle displaced inferior to the acromion or the coracoid
process
Treatment
Type I/II – conservative with rare surgery for type II
Type III – may or may not need acute surgery, conservative tx unless an overhead arm user
Type IV, V, VI - Surgery
Indications for Late surgical Treatment of AC injuries (if a Type I-III was treated and failed)
Pain, weakness, deformity
Clavicle Fractures
<5 mm – acceptable results at 5 years
>20 mm shortening associated with increased risk of nonunion, poor functional outcome
Treatment
Nonoperative – difficult to reduce clavicle fxs by closed means
They will heal, but are they healing correct? May not have union of fxed ends
Simple sling until signs of healing ROM exercises
Plate Fixation – ORIF (open reduction internal fixation)

Radial Head Fractures
Elbow Anatomy
3 joints: Humeral-ulnar, humeral-radial, proximal radial-ulnar
Valgus Elbow Stability – from MCL and radial head
MOI – usually a fall with axial load to elbow + valgus force
Could be combined with high energy injuries: elbow dislocation, coronoid fx, collateral lig injury
PE:
Neurovascular
Valgus stress, PLRI (valgus, supination, axial load)
Distal radio/ulnar joint stability
Forearm rotation
Radiographic Evaluation:
X-rays: AP, Lat, Oblique
MRI: ligamentous injury
Classification: 3 Types increasing in severity – not responsible for these for test
Treatment: radial Head Fixation
ORIF difficulties:
Communition is worse than anticipated
Fixation into the head is difficult
Essex - Lopresti Lesions
Defined as longitudinal disruption of forearm interosseous ligament, usually combined with
radial head fx and/or dislocation plus distal radioulnar joint injury
Difficult to diagnose
Treatment requires restoring stability of both elbow and Distal Radial Ulnar Joint components of
injury.
Radial head excision in this injury will result in disabling proximal migration of the radius.
Complications of Tx:
Improperly placed headward
Loss of fixation
Posterior interosseous nerve injury
Elbow Stiffness
MSK CCC 12: Thoracolumbar Spine Fractures
90% occur between T11 and L4, with 60% between T12-L2
Majority due to MVA
Biomechanics
Burst Fractures – from compression
Wedge Fractures – from Flexion
Fracture Dislocations – from Rotation
Seatbelt Type Fracutres – from shear
Thoracic spine – stabilized by ribs, MC flexion/compression injuries
Thoracolumbar junction– predisposed to rotation/axial compression injuries
B/w rigid thoracic and mobile lumbar spine
TL experiences compression when T goes into kyphosis and L goes to lordosis
Lacks ribs, transition point between Anterior facets and inward facets
Classification
Denis Three Column Model – to explain injuries/guide treatments
Columns: Anterior, middle*, and posterior
Instability = failure of 2+ columns
Middle distinguishes 4 types of spinal fractures
1st degree = mechanical
2nd degree = neurological
3rd degree = mechanical + neurological
Imaging:
Plain film series – most important with lateral being most informative
Pedicle or TP splaying
Fracture on lateral
Vertebral body widening
Listhesis
CT – bony anatomy
MRI – for spinal cord/ligament anatomy
Evaluation
Hx – blunt trauma must have spine cleared
Exam – sans clothes, full neuro exam (rectal tone, perianal sensation), log roll for bruising, deformity,
tenderness/crepitus, etc.
Imaging
X-rays – AP/Lat for all spinal injuries (excludes the most dangerous pathology)
CT – abdomen/pelvis for trauma management, abdominal can pick up TL fxs
MRI – upon request, useful for soft tissue and cord injuries
Classification of TL fractures:
Flexion-Compression
MC type, failure of anterior column, generally stable
Tx: Hyperextension orthosis, kyphoplasty, vertebroplasty, sx stabilization
Burst
Retropulse into canal + fx of posterior elements
Failure of anterior and middle columns = unstable
Widening of intrapedicular distance = decreasd body height
MC T10-T12
Tx: Decompress/stabilize with neurological deficits
Without neuro deficit – based on stability of fracture
Seat Belt/Chance
Hyperflexion-Distraction of posterior elements
Middle/posterior columns fail
S/S: Posterior tenderness, hematoma, interspinous widening + abdominal injuries
Tx: Osseous – bracing
Ligamentous - fusion
Fracture-Dislocation
All 3 columns under compression, distraction, rotation, or shear forces
Types:
A – flexion-rotation (3/4 with neuro deficit)
B – shear (all with neuro deficit)
C – flexion-distraction (3/4 with neuro deficit)
Tx: Rapid mobilization and rehab!
Treatments
One column = stable
Two columns = mixed, if neuro injury surgery
Three columns = surgery
Decompress neurological elements (remove structures causing compression)
Stabilize spine
Spine fusion
Corpectomy with retroperitoneal flank approach to decompress
Kyphosplasty for stable compression fractures – relieves pain
MSK CCC 13: Peds UE Disorders
Pediatrics vs. Adults
Overuse injuries are common
Bones bend before they break
Greenstick fractures,
Plastic deformity

Do at least 4 views: standing AP, lateral, 30° sunrise for patellar tracking, tunnel view)
Asses for arthritis, fracture, growth plate injury, loose body, joint effusion, alignment
Risk factors for Overuse Injury:
Biomechanical
Age:
Peds - rapid growth, usually injury to the apophysis (where tendon attaches to bone)
Middle aged – inadequate conditioning and flexibility
Senior – look for meds or underlying disease process
Extrinsic Factors:
Mechanical, coaching, environment, drug use, training
Classification:
Grade I – post activity pain only
Grade II – pain with activity, does not restrict
Grade III – pain with activity + restriction in performance
Grade IV – pain with activity & rest
Tendonitis (chronic or acute)
Causative factors: changes in mechanical loading or changes in muscle tendon extensibility
Intrinsic factors: structural failure due to overload, wkness, or a combo
Extrinsic Factors: impingement by bone or other structures
“choking the tendon”
Pediatric and Growth Issues
Apophyseal injury – traction induced microtrauma at tendon-bone junction
Physeal injuries – repetitive loading causing metaphyseal ischemica and poor growth in the
proliferative zone widening or narrowing of growth plate
Osgood Schlatter’s Disease – common cause of knee pain in active adolescents (M>F 10-14 years)
Diagnosis – localized pain at tibial tuberosity, no need for radiographs but they can confirm your
suspicion and exlude other causes of knee pain
Patho – microtrauma at deep fibers of patellar tendon at its insertion on the tibial tuberosity
“apophysitis”
Usually self-limited with resolution at skeletal maturity
Tx – relative rest and enhance strength/flexibility
Popliteal (Baker’s Cyst) – distended bursa in the popliteal space
MC bursa involved is beneath the medial head of the gastroc or semi-membranous tendon
Present with complaint of aching pain in the posterior knee/proximal calf
Diagnosis: AP, lateral, tangential X-rays of the knee
Adults – usually associated with intra-articular pathology
Tx: children – may resolve with time, occasionally have to excise
Adults – treat intra-articular pathology first, if discomfrt still remains excise (rare)
Lg, tense cysts can be aspirated with common recurrence
Sinding – Larsen – Johansson Syndrome – inflammation of patella at its inferior pole at the origin of the
patellar tendon, “traction injury”
S/S: swollen, warm, tender bump below the kneecap
Pain w/ activity especially when straightening the leg against force or post vigorous
activity, if more severe – pain with any activity
Tx: Ice, stretching, strengthening, exercises, modification of activities

Quad strengthening, flexibility (address kinetic chain)
Orthotics, icing, knee sleeve
Osteochondritis Dissecans – unknown etiology
S/S: generalized pain with swelling/aching post activity

Distal Femoral Condyle Fxs and Supracondylar Femur Fractures
Avulsion of Tibial Spine or “bicycle” fracture in children
Soft Tissue Trauma – rare to occur in children
Knee Ligament Tears
Internal: ACL/PCL will not heal on their own (ACL more commonly repaired – must do a graft)
Recovery takes 6 months
External: MCL/LCL – heal on their own
Meniscus Tears – require major trauma at young ages, but minimal twisting/squatting if >35 years
S/s: Pain along joint line, stiffness, mild swelling or knee with or without locking/catching
Audible popping with flexion/extension
Repair is one of the top 3 orthopedic surgical procedures done in US
Repaired with sewing/stapling if the tear is in the right location
Transplant cadaver menisci but unproven efficacy
Articular Cartilage Damage
Poor healing potential, nearly always leads to arthritis
Repair techniques:
Trimming/contouring of torn surface
Abrasion/micro fracture in an attempt to grow fibrocartilage repair cartilage
Filling a contained defect with cartilage and bone grafts from elsewhere
Growing autologous cartilage cells in tissue culture and implanting them
Combos of the above + Knee Dislocation
