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?

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

- THA
What is the clinical triad for a loose body presentation at the hip?
- noncapsular pattern of limitation
- pathological end feel
- sharp, shooting pain plus feeling of giving way that immediately follows the pain
What is the gold standard for diagnosing intraarticular loose bodies?
- arthroscopy
- CT and Xray often underestimates prevalence
A pt with hip pain presents with limited/altered end feel at end passive ranges of abduction and ER. What is the dx of concern?
- loose intraarticular bodies
- common clinical sign, in addition to the clinical triad
What is osteochondritis dissecans?
- begins with inflammation of the cartilage and subchondral bone
- The subchondral bone begins to die due to lack of blood flow, which can cause the bone and cartilage above to break off
- Rarely seen in the hip, but if it happens, it most commonly happens in the femoral head
T or F;
Osteochondritis dissecans is a loose body of cartilage/subchondral bone that has broken off due to lack of blood supply.
- F;
- it’s the death of the bone/cartilage, but it doesn’t always result in a loose body
What conditions can result in loose bodies? (3)
- osteochondritis dissecans
- synovial osteochondromatosis (SOCM)
- osteoarthrotic cartilaginous fronds breaking off with friction during movement
- also can be idiopathic
How do loose bodies form in synovial osteochondromatosis? (SOCM)
- chondral plaques begin to develop in the synovial tissue, and then can shear off and float within the synovial tissue
- will create multiple loose bodies
What are some general red flags for non-orthopaedic process related to hip pain? (10)
- age < 20 or > 50
- previous hx of CA
- trauma
- sacral pain in the absence of trauma
- osteoporosis
- hx of IV drug use
- hx of gastrointestinal, genitourinary, or gynecological infection or inflammation
- systemic signs associated with malignancy (cachexia, fever, night sweats)
- night pain
- pain at rest
What is the “sign of the buttock”?
- noncapsular pattern of limitation
- painfully limited passive hip flexion with knee both flexed and extended
- may be indicative of serious pathology in the hip
T or F;
Primary tumors of the bone in the pelvis are usually malignant.
- T
- Less often benign.
T or F;
Primary tumors of the bone in the femur are usually malignant.
- F
- usually benign

- breast cancer
- renal cell cancer
- thyroid cancer
- lung carcinomas
What is coxa saltans? Is it intra or extraarticular?
- snapping hip syndrome; a pretty broad dx
- can be considered intra or extraarticular
- Intraarticular is caused by the snapping of the iliopsoas tendon over the iliopectineal eminence
- extraarticular is related to thickening at the:
- iliotibial tract at the greater troch
- iliopsoas at the pectin pubis
- glute max fibrosis in the posterior hip
- proximal hamstring at the ischial tuberosity
- adventitious bursal formations at any of the above
What movements are typically limited or symptomatic with snapping hip syndrome?
- flexion, ER, or IR
- walking is often limited
Is surgery appropriate for a snapping hip syndrome?
- if persistent, yes it can be managed surgically
A pt presents 2 weeks after a trauma, reporting severe initial pain in their groin for a few days, but currently the pain is much better. They have some weakness with hip flexion however.
Avulsion fx is in the differential; but would this indicate a complete or incomplete avulsion?
- more consistent with complete.
- if incomplete, would expect the pain and weakness to persist at fairly high levels
An avulsion fx of which muscle may lead to a concommitent labral tear? What is the shoulder equivalent?
- rectus femoris, due to its periarticular origin
- thought to be similar to a SLAP tear
A pt presents with a dx of avulsion fx as a result of subluxation at the hip. What should be examined given this info?
- look for nerve involvement.
- increased concern for nerve entrapment/injury following subluxation with avulsion. Probably just the subluxation.
What imaging modes are appropriate to identify an avulsion fx?
- MRI
- US
What is the appropriate treatment course for an avulsion fx in the initial 4-6 weeks of dx?
- conservative care (whatever that means)
- and rest
- return to activity is typically as tolerated following the rest period

- T; although its efficacy has been questioned
What are the potential benefits of transverse friction massage for a tendinopathy?
- stimulates fibroblast proliferation/recruitment to promote tissue healing
