Extra-Articular Disorders of the Hip Flashcards
When examining a patient with hip condition : must rule out the following 3 things?
Sacroiliac Joint
Lumbar Spine
Knee/Foot/Ankle
Greater Trochanteric Pain Syndrome, which percent of population will get this?
10-25% will develop lateral hip pain
What is present in GTPS and where is it located?
Pain and reproducible tenderness in region of : greater trochanter, buttock, and lateral thigh.
What 3 contributing conditions can lead to GTPS?
Trochanteric Bursitis
Glut Med/Min/Piriformis Tendinopathy/Tears
ITB friction Syndrome/Snapping hip
Risk factors for GTPS?
Older than 40 Female Obese Knee/Hip OA RA Core instability Lumbosacral back pain
Mechanisms of Injury GTPS?
Direct trauma to hip Eccentric Hyperadduction Cumulative Microtrauma IT impingement Intrinsic degenerative tendinosis of hip abductors
What is the most common finding on an MRI for people with GTPS? What is rarely found?
Intrinsic degenerative tendinosis of hip abductors.
Rarely is trochanteric bursitis identified.
Clinical presentation of GTPS?
What exacerbates the pain?
Acute onset of pain lateral thigh, radiates down to calf on occasion.
Lying on the affected hip.
Repetitive hip flexion-extension activites
Prolonged standing or single limb activity
Repetitive hip internal or external movements
Examination of GTPS signs?
What reproduces the pain?
Need to rule out what?
Tenderness in the posterolateral area of GT; on either side of the glute med tendon
Pain reproduced with : Stretching of IT band (Ober’s Test)
-Active resistance of hip abduction and external rotation. Occasionally internal rotation.
Pain rarely reproduced with hip extension**
Pain with Straight Leg Standing for 30 seconds. 100% sensitivity.
- Positive trendelenberg
- Resisted external derotation test 97% SP
Need to rule out lumbar spine radiculopathy!
Piriformis Syndrome?
What percent of population affected
What presents?
Etiology?
Sciatic nerve passes through piriformis in 15% population.
Spasm/Hypertrophy of pirfiromis compresses the sciatic.
Presents with abnormal neuro findings in affected nerves
Etiology: multivariate . Compression of nerve, muscle imbalance, trauma, strain or overuse
Piriformis syndrome may start as what, and progress where?
Aggravated by?
Buttock pain and progress to posterior thigh and calf pain
Aggravated by walking , extended sitting, external rotation of hip
Examination for pirformis syndome?
Antalgic Gait May stand with ER leg AROM hip ER may cause pain Positive SLR with IR/ADD Weak hip ER and MMT pain Palpable tenderness in piriformis
Positive piriformis test
Patient in side-lying on uninvolved side with involved side place 60 degrees of hip flexion
Stabilize pelvis apply adduction force to opposite side.
Positive test- if movement reproduces patient’s pain in buttock leg
Snapping Hip Syndrome?
Which gender gets it more?
Females.
Patient complains of snapping noise, occasional pain.
3 classifications: External, Internal, Intra-Articular
Snapping hip syndrome: External
Tight ITB or glute Max over the greater trochanter
Snapping hip syndrome: Internal
Iliopsoas tendon over anterior acetabulum OR iliofemoral ligament over femoral head
Snapping common during hip flexion of 45 deg
Snapping hip: intra-articular
Loose body in joint from a Labral Tear
Examination: what to do? Snapping hip
Rule out intra-articular cause of snapping hip.
Snapping hip Sign
Palpate!
How to rule out intra-articular causes of snapping hip?
FADIR and Thomas Test
What is snapping hip sign?
Patient abducts and ER leg, moving into flexion and then extension.
Reproduces snapping around 45 deg.
Femoral Stress Fractures are most common where? And what percent of people will get them?
What is the most common place for a stress fracture in the femur?
Tibia and Metatarsals
7-10% in the femur
Most common in the shaft
Risk factors for stress fractures: Extrinsic
Frequency, duration, intensity, surface, footwear
Risk factors for stress fracture: Intrinsic
Poor muscular endurance/decreased muscle mass
What is the female triad?
Disordered eating, Amenorrhea, osteoporosis
Femoral Neck stress fractures are at higher risk for displacement on which side? How is it treated?
What about the other side?
Tension side (superior aspect of femoral neck) Treated with an ORIF
Compression side is treated conservatively
Femoral Shaft stress fractures occur mostly where?
Medial proximal third and treated conservatively
Diagnosis of femoral stress fractures?
Radiograph, Bone Scan, MRI
Examination of stress fractures?
Subjective
Patient complains of localized pain insidious onset in groin, thigh or knee.
Pain at end of a run that may progress.
Usually related to a change in activity level.
Hard to illicit pain with palpation
Which test can be used with high sensitivity for stress fracture femur?
Patella-pubic percussion test at 95%
Or fulcrum test
Fulcrum Test?
Possible proximal 1/3 femoral stress fracture
Patient’s femur is leveraged over examiner’s forearm and positive when pain is reproduced.
