Hip APTA (2) Flashcards
What is the standard demographic affected by slipped capital femoral epiphysis (SCFE)?
- usually male (2:1) between 13-15yo, otherwise female between 11-15 yo. Essentially during pubescent years
- frequently w/ males who are overweight and underdeveloped
A 13 yo female presents with R hip pain that is in a noncapsular pattern. What is primary in the differential?
- SCFE
What are the odds a pt with SCFE will get it in the other hip?
- 30% chance of asynchronous B involvement
T of F;
SCFE will develop acutely.
- F-ish. The slipping event can occur gradually or more acutely
What does SCFE initially present as?
- if acute, usually significant groin pain that prohibits weight bearing in functional activities
- if more gradual, starts as mild groin pain or anterior knee pain
With slipping that advances in SCFE, what may be found clinically?
- muscle guarding
- limited IR with increased ER
- and obligatory abduction and ER (Drehmann sign)
- Trendelenburg
What is Drehmann sign?
- obligatory abduction and ER with passive hip flexion
- associated with SCFE and FAI
What structural dysfunction may be associated with SCFE?
- cam type FAI
What is the common treatment for SCFE?
- surgical pinning
- 4-6 weeks of partial WB with AD until callus formation
Avascular necrosis is associated with which diagnoses?
- in children, LCPD and SCFE
- in adults, is less clear
What type of imaging may be helpful in early recognition of LCPD?
- CT
What are the 4 stages of LCPD?
- stage I: 25% of the femoral head is involved and the CFJ has increased articular space
- Stage II: 50% of the femoral head is involved; crescent sign (half moon), with intact anterior pillar of femoral head
- Stage III: 75% femoral head involvement with progressive femoral head collapse
- Stage IV: 100% femoral head and plate involvement
What is the primary concern for management of LCPD?
- prevention of further collapse and displacement
Bracing strategies for LCPD typically involve ensuring the pt is able to maintain what two ROMs?
- abduction and IR
Exercise for LCPD is typically targeting _______ to promote _________.
- abduction to promote containment
Are noncontainment strategies appropriate for LCPD management?
- probably not. Are associated with poor articular outcomes in 68% of adults who were diagnosed with LCPD as a child
What are potential surgical management procedures for LCPD?
- innominate osteotomy (Salter procedure; increases acetabular coverage of the femoral head)
- acetabular rotation osteotomy (Chiari procedure)
- medial or lateral femoral wedge derotation osteotomy
What is appropriate management post osteotomy for LCPD?
What is a precaution following the procedure?
- first few days post-op can do passive ROM
- active hip flx and abduction should be avoided for the first 40 days post-op
What is an appropriate intervention to help mitigate risk of hip flx contracture for post-op osteotomy pts?
- prone positioning
How long can PWB be expected to be maintained post-op osteotomy management for LCPD?
- 3-6 months
How long can avascular necrosis of the hip in adults take to develop?
- can be acute, or can take months to years to develop
What are the typical signs/symptoms for an avascular necrosis of the hip in an adult?
- gradual increase in groin pain, with possible ROM limitations
- as it progresses, the symptoms increase, as well as potential for crepitus, with pain referral to glutes, anterior thigh, and knee
What are some minimally nonsurgical treatment options for adult AVN? (7)
- bisphosphonates
- anticoagulants
- statins
- vasodilators
- extracorporeal shock wave therapy
- pulsed electromagnetic therapy
- hyperbaric oxygen
How long will it be until a pt who has had an osteotomy or core decompression for AVN is able to WBAT?
- 3-6 months
