Q

What is the management of Slipped Upper femoral epiphysis

Study These Flashcards
A
  • Urgent surgical repair: screw fixation

* Prophylactic fixation of contralateral hip

23
Q

What Investigations should be undertaken if suspecting Slipped upper femoral epiphysis

Study These Flashcards
A
  • Bilateral AP x rays: Klein’s line doesn’t intersect femoral head
  • Bilateral Frog laterals: Bloomberg’s sign: Physis is blurred/widened
  • ? metabolic panel: TFTs, serum GH
24
Q

What are the complications of slipped upper femoral epiphysis

Study These Flashcards
A
  • Long term OA – 90%
  • Avascular necrosis of femoral head 10-15%
  • Chondrolysis: acute cartilage necrosis
  • Deformity
  • Limb length discrepancy
25
What are the signs and symptoms of Juvenile idiopathic arthritis
* Joint pain – often knee * Joint swelling/effusion * Morning stiffness: not like first nappy change * Limp/decreased movement * Non-puritic salmon coloured rash on trunk and proximal extremeties * Enthesis: inflammation of tendon and ligament insertions on bone
26
What are the risk factors for Juvenile idiopathic arthritis
* Female * HLA polymorphism * FH autoimmunity * <6 years old
27
What investigations should you consider if suspecting Idiopathic arthritis
* FBC: normal, decreased Hb or increased platelets * ESR/CRP: can be raised * RF * Anti-CCP * ANA * Chlamydia in teenage? * USS joint * Ferritin
28
Complications of Juvenile idiopathic Arthritis
``` • Low mood • Eye inflammation: 10-20% uveitis • Stiff joints • Medications can have an impact on - Growth - Puberty ```
29
What is the acute management of Juvenile idiopathic arthritis
Physio | Pain relief - NSAIDs
30
what is the chronic management of juvenile idiopathic arthritis
Disease modifying drugs - methotrexate/sulfasalezine Folic acid pain relief
31
What are the risk factors for Developmental Dysplasia of the hip?
- First born - Female - Breech - FH - Oligohydramnios - Macrosomia - Swaddling - cultural
32
Dysplasia definition
Shallow or underdeveloped acetabulum (usually ant or anterolateral)
33
Subluxation definition
displacement of the joint with some contact remaining between the articular surfaces
34
What is a teratologic hip
o dislocated in utero and irreducible on neonatal exam o presents with a pseudoacetabulum o associated with neuromuscular conditions and genetic disorders o commonly seen with arthrogryposis, myelomeningocele, Larsen's syndrome, Ehlers-Danlos
35
What does the barlow test do
Dislocates a dislocatable hip by adducting and depressiong a flexed femur – ‘click of exit’
36
What does the ortolani test do
Reduces a dislocated hip be elevation and abduction of a flexed femur – ‘click of entry’
37
What is the Galaezzi test
Hip flexed at 90 degrees, feet on table, femur appears shortened on dislocated side
38
what would you find on examination between 3-12 months in developmental dysplasia of the hip
- Limitations of hip abduction: laxity resolves and stiffness begins to occur (most sensitive) Will be decreased symmetrical in bilateral disloations. - Limb length discrepancies
39
What is the klisic test
o used to detect bilateral dislocations o line from the long finger placed over the greater trochanter and the index finger over the ASIS should point to the umbilicus o if the hip is dislocated, the line will point halfway between the umbilicus and pubis
40
What would you find on examination >12 months in a child with developmental dysplasia of the hip?
- pelvic obliquity - lumbar lordosis: in response to hip contractures resulting from bilateral dislocations in a child of walking age - Trendelenburg gait : results from abductor insufficiency - toe-walking: attempt to compensate for the relative shortening of the affected side
41
When would you do an Xray if suspected developmental dysplasia of the hip
o Primary imaging >4-6 months as femoral head begins to ossify o Positive physical exam o Leg length discrepancy - AP view of pelvis
42
When would you do an US scan if suspecting developmental dysplasia of the hip
- 4 weeks – 6 months - Positive physical exam - RF - Monitoring of reduction using Pavlik harness - Not cost effective for routine screening
43
What are the non operative management options for developmental dysplasia of the hip
- abduction splinting/bracing (Pavlik harness) | -
44
indications/contraindications for abduction splinting/bracing (Pavlik harness)
- Indications o < 6 months old and reducible hip - Contraindications: o teratologic hip dislocations and patients with spina bifida or spasticity  requires normal muscle function for successful outcomes
45
What are the indications for closed reduction and spica casting
o 6-18 months old | o failure of Pavlik treatment
46
What are the operative management options for developmental dysplasia of the hip
Open reduction and spica casting Open reduction and femoral osteotomy Open reduction and pelvic osteotomy
47
What are the indications for Open reduction and spica casting
o > 18 months old | o failure of closed reduction
48
What are the indications for Open reduction and femoral osteotomy in developmental dysplasia of the hip
o > 2 years old with residual hip dysplasia o anatomic changes on femoral side (e.g., femoral anteversion, coxa valga) o best in younger children (< 4 years old) - after 4 years old, pelvic osteotomies are utilized
49
What are the indications for Open reduction and pelvic osteotomy
o > 2 years old with residual hip dysplasia o severe dysplasia accompanied by significant radiographic changes on the acetabular side (increased acetabular index) o used more commonly in older children (> 4 yr) o decreased potential for acetabular remodeling as child ages
50
What are the risk factors for septic arthritis
* Underling joint disease * Joint prosthesis * IVDU * DM/cutaneous ulcers * Intra-articular steroid injections * Low socioeconomic status * Hx or RA or OA
51
What are the signs and symptoms of septic arthritis
* Hot, swollen, tender, restricted joint * Short Hx of Sx * Fever
52
What investigations would you order if you suspected septic arthritis
* Synovial fluid, gram stain and culture and WCC * Blood culture * FBC * CRP/ESR * USS: effusion for aspiration * X-ray: degeneration changes?
53
What is the management of septic arthritis
* IB Abx + joint aspiration for 2 w * Oral Abx 4 weeks further * RISK OF OSTEOMYELTIIS AND JOINT DESTRUCTION
