W9 Flashcards
Causes of buttock pain - common
Proximal Hamstring Tendinopathy
Proximal Hamstring Tendinopathy Aetiology
- Caused by compression of the hamstring tendon against ischial tuberosity
- Common in sports that involve sprinting, jumping or repeated hip flexion and extension movements
Proximal Hamstring Tendinopathy Clinical Presentation
Sudden or gradual onset posterior buttock pain
* initially with sports
* as progresses pain also with ADLs – walking, stairs, sitting (especially on hard surfaces)
Proximal Hamstring Tendinopathy
Physical Examination
- TOP (tender on palpation)
- Replication of aggravating factors = reproduction of Sx (symptoms)
- Sx/pain reproduced with hamstring stretch or contraction (remember biarticular origin and insertion)
Proximal Hamstring Tendinopathy Diagnostic Imaging
- MRI or U/S (ultrasound)
- Thickening, oedema, increased signal intensity
- Helpful for DDx (differential diagnosis) of tendon
versus, or includes, the ischiogluteal bursa
Causes of buttock pain – less common
Piriformis Syndrome
Piriformis Syndrome
Aetiology – highly debated
? Enlarged, inflamed and/or tight piriformis causing mechanical compression of the
sciatic nerve.
* Anatomical variations in course of the sciatic nerve.
? Neurological condition or myalgia due to gluteal weakness
* Frequent hip flexion, IR and adduction (e.g. cycling, skiing, dance, gymnastics)
Piriformis Syndrome
Clinical Presentation
- Either gradual or acute traumatic onset
- Deep and diffuse, central buttock Sx.
- Aggs = sitting > standing; stretching buttocks.
Piriformis Syndrome
Physical Examination
- TOP
- Possible decreased hip flexion, adduction and/or IR ROM due to pain or reduced length, OR
- decreased strength of hip extensors, abductors and/or ER, OR
- Faulty hip extension pattern
- FADER-R may reproduce Sx
- Neurodynamic SLR to DDx
causes of HIP PAIN
Labral Tear
Osteoarthritis
Hip Joint Instability
Gluteus Medius Tears & Tendinopathy
Trochanteric Bursitis- less common
Ligamentum Teres Tear
Femoroacetabular Impingement
Labral Tear (common hip pain) aeitology
- Trauma - single or repetitive trauma – rotation & flexion, repetitive pivoting, hip flexion, twisting or direct trauma (fall/MVA)
- Congenital – due to acetabular or hip dysplasia
- Degenerative – may be associated with OA
- Capsular laxity – due to systemic connective tissue disorder or repetitive activities
- Idiopathic - may be associated with FAI (Cam or pincer morphology) Syndrome
- Most common intra-articular hip injury in athletes (22% of athletes with hip pain).
Labral Tear (common hip pain) Clinical Presentation
Anterior groin pain
* Gradual onset of symptoms or related to trauma/injury
* Pain increases with activities
* intermittent, sharp “catching” pain, clicking, locking, catching, giving way
* referred pain to the buttock and/or anterior thigh
Labral Tear Physical Examination
- Hip Quadrant, and/or
- FADIR, and/or
- Thomas Test IF reproduction of patient’s pain and/or click
- FABER IF reproduction of patient’s Sx
- Possible glut med and/or lower fibres of glut max atrophy
Labral Tear
Diagnostic Imaging
- MRI and MRA most sensitive
- CT
Labral Tear Diagnostic Surgery
Arthroscope
Osteoarthritis (O.A) commom
Aetiology
- Age-related response to abnormal loading from an acute traumatic event or repetitive microtrauma.
- Trauma = cartilage degradation = inflammatory response = further cartilage damage.
Damage to subchondral bone
Hypertrophic (osteophytic) and/or atrophic bone response
Bone necrosis and periostitis
Synovial inflammation and thickening
OA clinical ptresentation
Local Sx, usually affecting a single joint, and develops gradually
* Morning stiffness < 1 hour
* Pain and stiffness in the affected joint, leading to muscle changes and functional limitations.
* May have gait changes (slower; shorter step length; greater step width; greater step duration)
non modifiable factors for hip OA
- Age – increased risk in >55 year olds, with further increased risk in >65- 80 year old
- Gender/sex – increased risk in women
- Genetic/familial predisposition
- Ethnicity or Race – lower incidence in Asian cultures than white
Caucasian. Very low incidence in Koreans - Leg length difference
- History of lower limb or hip trauma
modifiable factors for hip OA
- Occupational factors
- manual labor /physical stress work
- sporting activities
- Increased weight or obesity (BMI)
- questionable for development of OA but Yes for progression of OA)
Osteoarthritis (O.A)
Physical Examination
AROM- hip internal rotation less than 15 degrees
AROM- hip flexion less than 115 degrees
FABER will reproduce symptomes
quadrant test will be positive (will be positive in labers tear as well)
Osteoarthritis (O.A)
Diagnostic Imaging
- X-ray
- CT
- MRI
Hip Joint Instability aeitology
Causes of hip pain - common
- Capsuloligamentous laxity
- Traumatic
- hip dislocation - fall on flexed knee & hip or from dashboard (MVA)
- repetitive rotation movements with axial loading
- Trauma -> stretching of capsule, possible labral damage /tears of ligamentum teres
- Recurrent dislocation
- Atraumatic
- In congenital-hypermobility conditions = generalized ligamentous laxity and/or acetabular dysplasia
- Certain sports, including football, golf, horse riding, dance, gymnastics
Hip Joint Instability clinical presentation
Causes of hip pain - common
feeling of instability, clicking and/or clunking
* pain in hip/groin region which may increase with activity
Hip Joint Instability- Physical Examination
Causes of hip pain - common
Extremes of end AROM and PROM and PAM
ROM (significantly increased compared to normal)
* May also observe:
* Poor balance
* Poor control in functional tasks
* Excessive anterior translation of femoral
head, especially during Lx and/or hip extension
* Global hypermobility syndrome
* Hip clicking and/or clunking
