Musculoskeletal/Sports injuries Flashcards
-the growth plate
Physis
-the end of the long bone, adjacent to the growth plate or physis
metaphysis
-when the distal part of the deformity points inward
Varus
-when the distal part of the deformity points away from midline
Valgus
Pain Paresthesias Pallor Paralysis Pulselessness
Compartment Syndrome
- blue sclerae
- fractures during preschool years
- autosomal dominant
- hearing loss (both kinds)
- bad teeth associated with Type 1B
- type 2 is the most severe form and is usually lethal (bag of bones stillborn delivery)
- type 3 is the progressive deforming type, born with fractures, macrocephaly and short stature
Osteogenesis Imperfecta
- macrocephaly, frontal bossing, midface hypoplasia, and proximal shortening of the limbs
- MC cause of sudden death is cervicomedullary junction compression
- 80% of cases occur as a spontaneous mutation
Achondroplasia
- infant with head tilted to one side
- mass in the SCM
- facial asymmetry
- Tx: daily stretching and PT, then surgery
- can be associated with hip dysplasia
Congenital Torticollis
- infants with repeated attacks of head tilting which only last for minutes at a time.
- often accompanied by vomiting, irritability, and pallor
- require no intervention
Paroxysmal Torticollis
- head tilt with UMN findings (increased DTRs)
- Dx: MRI
Posterior fossa tumor
- fusion of the cervical vertebrae
- short neck and low occipital hairline
- scoliosis, spina bifida, renal probs, Sprengel deformity, deafness
Klippel-Feil Syndrome
- the convex alignment of the thoracic spine in the sagittal plane
- 20-40 degrees is normal
- < 60 degrees: no intervention
- > 60 degrees: PFTs
Kyphosis
- bad posture, back pain, and kyphosis in a teenager
- presents at puberty
- Tx: NSAIDs, PT
Scheurmann disease
- -results from poor fetal development and the failure of the scapula to descend to its normal position
- affected side of neck will seem broader and shorter
- mimics torticollis
Sprengel Deformity
- MC on the left
- Dx: US
- asymmetric gluteal folds
- Tx: Pavlik harness (not double diapering)
- Risks: breech, FHx, female, first born
Developmental Dysplasia of the Hip
-adduction of the hip with downward pressure
Barlow
-abduction of the hip with attempt at relocating a dislocated femoral head
Ortolani
- recent URI
- some passive ROM of the painful joint
- normal ESR
- negative gram stain
- normal or slightly elevated temperature
- Dx of exclusion
- Tx: reassurance
Toxic synovitis
- MC hematogenous spread
- high fever, joint warm to touch, little or no PROM
- positive gram stain, elevated ESR
- increased joint space on Xray
- MC younger than 2yo
- Tx: aspiration, Abx to cover S. aureus
Septic joint
-migratory arthritis coupled with a rash
Rheumatic fever
-avascular necrosis of the femoral head
-MC boys 4-8 yo
-Xray: one femoral head smaller than the other
-hip pain may be referred to the knee
(Forrest Gump)
Legg Calve Perthes Disease
- infection of the bone
- MC S. aureus
- MRI is most sensitive (but not specific)
- Bone scan is most specific
- begins with an episode of bacteremia seeding to the metaphysis
- can spread by local extension
- Dx: direct aspiration of the metaphysis
- Xray findings do not usually appear until 10-14 days after infection
- Tx: PO meds can be used when there is a good response to IV meds and an organism is identified
Osteomyelitis
- chronic knee pain that locks and swells
- MC in adolescent boys
- necrosis of the articular surface of a joint
- Dx: MRI
- Tx: immobilization and surgical removal of fragments
Osteochondritis Dessecans
- results from the stress at the insertion of the patellar tendon at the anterior tibial tubercle from excessive activity
- adolescent who presents with pain just below the knee
- Tx: couple weeks rest with gradual resumption of activity, NSAIDs
