Chapter 74 / Orthopaedic Surgery 715

What is the usual

Pain and swelling; pathologic fractures

presentation?

are rare

What is the treatment?

Curettage and bone grafting

ARTHRITIS

 

 

 

 

Which arthritides are

Osteoarthritis

classified as degenerative?

Post-traumatic arthritis

What signs characterize

Heberden’s nodes/Bouchard’s nodes

osteoarthritis?

Symmetric destruction, usually of the

 

 

hip, knee, or spine

What are Bouchard’s nodes?

Enlarged PIP joints of the hand from

 

cartilage/bone growth

What are Heberden’s nodes?

Enlarged DIP joints of the hand from

 

cartilage/bone growth

What is post-traumatic

Usually involves one joint of past trauma

arthritis?

 

 

What are the treatment

1. NSAIDS for acute flare-ups, not for

options for degenerative

 

long-term management

arthritis (3)?

2.

Local corticosteroid injections

 

3. Surgery

What are the characteristics

Autoimmune reaction in which invasive

of rheumatoid arthritis?

pannus attacks hyaline articular cartilage;

 

rheumatoid factor (anti-IgG/IgM) in 80%

 

of patients; 3 more common in

 

women; skin nodules (e.g., rheumatoid

 

nodule)

What is pannus?

Inflammatory exudate overlying synovial

 

cells inside the joint

What are the classic hand

Wrist: radial deviation

findings with rheumatoid

Fingers: ulnar deviation

arthritis?

 

 

What are the surgical

1.

Arthroplasty

management options for

2.

Arthrodesis (fusion)

joint/bone diseases (3)?

3. Osteotomy

716 Section III / Subspecialty Surgery

What is the major difference between gout and pseudogout?

Gout: caused by urate deposition, negative birefringent, needle crystal

Pseudogout: caused by calcium pyrophosphate positive birefringent square crystals (Think: Positive Square crystals PSeudogout)

What is a Charcot’s joint?

Arthritic joint from peripheral

 

neuropathy

PEDIATRIC ORTHOPAEDICS

 

 

 

What are the major differences between pediatric and adult bones?

Children: increased bone flexibility and bone healing (thus, many fractures are treated closed, whereas an adult would require O.R.I.F.), physis (weak point)

What types of fractures are

Greenstick fracture

unique to children?

Torus fracture

 

Fracture through physis

SALTER-HARRIS CLASSIFICATION

 

 

 

What does it describe?

Fractures in children involving physis

What does it indicate high

Potential growth arrest

risk of?

 

Define the following terms:

 

Salter I

Through physeal plate only

Salter II

Involves metaphysis and physis

Salter III

Involves physis and epiphysis

Salter IV

Extends from metaphysis through physis,

 

into epiphysis

Salter V

Axial force crushes physeal plate

Chapter 74 / Orthopaedic Surgery 717

Define the following fractures by Salter-Harris grade:

Salter III

Salter IV

Salter I

Salter V

718 Section III / Subspecialty Surgery

What acronym can help you remember the Salter classifications?

What is the simple numerical method for remembering the SalterHarris classification?

Salter II

“SALTR”:

Separated type I Above type II Lower type III Through type IV Ruined type V

(N normal)

Why is the growth plate of concern in childhood fractures?

Growth plate represents the “weak link” in the child’s musculoskeletal system; fractures involving the growth plate of long bones may compromise normal growth, so special attention should be given to them

Chapter 74 / Orthopaedic Surgery 719

What is a chief concern when oblique/spiral fractures of long bones are seen in children?

What is usually done during reduction of a femoral fracture?

What is unique about ligamentous injury in children?

What two fractures have a high incidence of associated compartment syndrome?

Child abuse is a possibility; other signs of abuse should be investigated

Small amount of overlap is allowed because increased vascularity from injury may make the affected limb longer if overlap is not present; treatment after reduction is a spica cast

Most “ligamentous” injuries are actually fractures involving the growth plate!

1.Tibial fractures

2.Supracondylar fractures of humerus (Volkmann’s contracture)

CONGENITAL HIP DISLOCATION

What is the epidemiology?

Female male, firstborn children,

 

breech

 

Presentation, 1 in 1000 births

What percentage are bilateral?

How is the diagnosis made?

What is Barlow’s maneuver?

10%

Barlow’s maneuver, Ortolani’s sign Radiographic confirmation is required

Detects unstable hip: patient is placed in the supine position and attempt is made to push femurs posteriorly with knees at 90 /hip flexed and hip will dislocate (Think: push Back Barlow)

What is Ortolani’s sign? “Clunk” produced by relocation of a dislocated femoral head when the examiner abducts the flexed hip and lifts the greater trochanter anteriorly; detects a dislocated hip (Think: Out Ortolani’s)

What is the treatment? Pavlik harness—maintains hip reduction with hips flexed at 100 to 110

720 Section III / Subspecialty Surgery

SCOLIOSIS

What is the definition?

Lateral curvature of a portion of the spine

 

 

Nonstructural: corrects with positional

 

 

change

 

 

Structural: does not correct

What are three treatment

1.

Observation

options?

2.

Braces (Milwaukee brace)

 

3.

Surgery

What are the indications for

Respiratory compromise

surgery for scoliosis?

Rapid progression

 

Curves 40

 

Failure of brace

MISCELLANEOUS

Define the following terms: Legg-Calvé-Perthes disease

Slipped capital femoral epiphysis

Idiopathic avascular necrosis of femoral head in children

Migration of proximal femoral epiphysis on the metaphysis in children; the proximal femoral epiphysis externally rotates and displaces anteriorly from the capital femoral epiphysis, which stays reduced in the acetabulum

(Note: Hip pain in children often presents as knee pain)

Blount’s disease

Idiopathic varus bowing of tibia

Nursemaid’s elbow

Dislocation of radial head (from pulling

 

toddler’s arm)

Little League elbow

Medial epicondylitis

Osgood-Schlatter’s

Apophysitis of the tibial tubercle resulting

disease

from repeated powerful contractions of

 

the quadriceps; seen in adolescents with

 

an open physis

 

Treatment of mild cases: activity

 

restriction

 

Treatment of severe cases: cast

What is the most common

Osteochondroma (Remember, 80% of

pediatric bone tumor?

bone tumors are benign in children)
