HIP - SNAPPING HIP SYNDROME
- A palpable or audible snapping sensation that is heard during the movement of the hip joint.
HIP - SNAPPING HIP SYNDROME - CAUSE
- Most commonly a result of overuse
- External snapping hip syndrome most commonly is caused by the iliotibial band snapping over the greater trochanter of the femoral head during movements such as flexion, extension, and external or internal rotation.
- Internal snapping hip is most commonly caused by the iliopsoas tendon snapping over underlying bony prominences, such as the iliopectinal eminence or the anterior aspect of the femoral head.
HIP - SNAPPING HIP SYNDROME - POPULATION AFFECTED
- Slightly more common in women than men
Heavy labour jobs, ballet dancers, weight lifters
liotibial band tightness, shorter muscle or tendon lengths, muscle tightness
HIP - SNAPPING HIP SYNDROME - CLINICAL PRESENTATION
- External SHS may also have coxa vara, fibrotic scar tissue, a prominent greater trochanter, smaller lateral pelvic width, or a past surgery for anterolateral knee instability.
- Internal SHS Ps describe a painful sensation coming from deep within the anterior groin as they move their hip from flexion into extension or external rotation.
- The snapping movement can produce an auditory clunk or click.
- Pain
- Inflammation
- Feeling like hip is dislocation
- Leg muscle weakness
- Swelling
- Difficulty standing up from a chair
HIP - ACQUIRED DISLOCATION OF THE HIP
- Hip dislocation is the displacement of the femur head from the acetabulum
HIP - ACQUIRED DISLOCATION OF THE HIP - CAUSE
- Majority from motor vehicle collisions - posterior dislocations
HIP - ACQUIRED DISLOCATION OF THE HIP - POPULATION AFFECTED
- More common in elderly/females
- Within 3 months of a hip replacement surgery
HIP - ACQUIRED DISLOCATION OF THE HIP - CLINICAL PRESENTATION
- The hip will be shortenend, in external rotation, slight flexion and adduction in the more common posterior dislocations.
HIP - COXA VARA
- Normal femoral neck-shaft is 160deg in adults – angle less than 120deg is called coxa vara. Can be either congenital (CCV) or acquired (ACV).
- CCV due to defect of endochondral ossification in medial part of femoral neck
When child starts to crawl or stand the femoral neck bends or develops a stress fracture - Infancy and early childhood (CCV)
- ACV can develop at any age if the femoral neck gives way
- Limb length discrepancy, Leg is short, thigh may be bowed
- Prominent greater trochanter
- Limitation of abduction and internal rotation of the hip
HIP - FEMORAL ANTEVERSION
- The femur turns inwards causing the whole leg to turn in
HIP - FEMORAL ANTEVERSION - CAUSE
- Excessive anteversion of the femoral neck, so that the internal rotation of the hip is increased and external rotation is diminished.
HIP - FEMORAL ANTEVERSION - POPULATION AFFECTED
- Most evident in children 2-4
- Twice as common in girls than boys
HIP - FEMORAL ANTEVERSION - CLINICAL PRESENTATION
- When a child walks or runs, the feet turn inward instead of pointing straight ahead
- Usually sit on floor with knees facing each other – should be advised to sit with knees facing outwards
HIP - PYOGENIC ARTHRITIS
- Bacterial, viral or fungal infections - spreads through the bloodstream to a joint.
HIP - PYOGENIC ARTHRITIS - CAUSE
- Lining of your joints has little ability to protect itself from infection. Your body’s reaction to the infection — including inflammation that can increase pressure and reduce blood flow within the joint — contributes to the damage.
HIP - PYOGENIC ARTHRITIS - RISK FACTORS
- Children under 2
- Complication of joint surgery
- Diabetes mellitus
- Immunodeficiency
- Pre-existing joint disease, Rheumatoid arthritis
HIP - PYOGENIC ARTHRITIS - CLINICAL PRESENTATION
- Child is in pain and ill
- Hip movements resisted to total lack of ROM
- Aspiring pus from joint
- Severe joint pain, usually in just 1 joint, that started suddenly
- Swelling around a joint
- Skin around a joint has changed colour
- Pt feels generally unwell and have a high temperature or feel hot and shivery
HIP - RHEUMATOID ARTHRITIS
- Autoimmune disease.
- This means your immune system attacks the cells that line your joints by mistake, making the joints swollen, stiff and painful.
HIP - RHEUMATOID ARTHRITIS - POPULATION AFFECTED
- Women more likely to get it than men
- Develops mainly 30-60
- 16-40 diagnosed as early onset RA
HIP - RHEUMATOID ARTHRITIS - CLINICAL PRESENTATION
- Usually, Pt has RA in many other joints
- Groin pain comes on subtly
- Limp common, may be as a result of knee or ankle RA too
- Wasting of buttock or thigh muscles, limb usually held in external rotation and fixed flexion
- Painful and restricted in all ROM
HIP - OSTEOARTHRITIS
- Most common non-traumatic disorder of the hip in the middle and late age
HIP - OSTEOARTHRITIS - CAUSE
- Usually no specific cause
HIP - OSTEOARTHRITIS - POPULATION AFFECTED
- <50
- In younger Ps (under 40) may appear as a sequel to childhood and adolescent disorders, such as coxa vera, perthes’ disease and Femoroacetabular impingement
HIP - OSTEOARTHRITIS - CLINICAL PRESENTATION
- Typically occurs after periods of activity
- Later becomes more constant and sometimes disturbs sleep
- Stiffness most notable after waking up
- Limp
- Limited ROM
HIP - FEMOROACETABULAR IMPINGEMENT
- Femoral head (ball of the hip) pinches up against the acetabulum (cup of the hip). When this happens, damage to the labrum (cartilage that surrounds the acetabulum) can occur, causing hip stiffness and pain, and can lead to arthritis.
HIP - FEMOROACETABULAR IMPINGEMENT - CAM
- Cam – deformity at femoral head/neck junction, an unusual degree of bony thickening causes jamming of femoral neck against front of acetabulum and abrasion of articular cartilage
HIP FEMOROACETABULAR IMPINGEMENT - PINCER
- Pincer – over-coverage of femoral head by anterior edge of acetabulum due to depth or retroversion of acetabular socket at a localised site. Hard acetabular margin abuts against the femoral head during movement causing degeneration of the acetabular labarum and adjacent articular cartilage
HIP - ILIOPECTINEAL BURSITIS
- Largest bursa in the region of the hip joint
HIP - ILIOPECTINEAL BURSITIS - CAUSE
- Trauma, osteoarthritis, rheumatoid arthritis, septic arthritis
HIP - ILIOPECTINEAL BURSITIS - CLINICAL PRESENTATION
- Pt may have radicular pain and edema from groin to anterior thigh as enlargement of the bursa can irritate or entrap the femoral nerve and vein.
HIP - TROCHANTERIC BURSITIS
- Inflammation of the bursa at the outside (lateral) point of the hip known as the greater trochanter
HIP - MERALGIA PARASTHETICA
- Disorder characterised by tingling, numbness, and burning pain in the outer side of the thigh - may intensify after walking.
HIP - MERALGIA PARASTHETICA - CAUSE
- Tight clothes, trauma
- Compression of the lateral femoral cutaneous nerve, a sensory nerve to the skin, as it exits the pelvis.
- Often under the inguinal ligament, which runs along your groin from your abdomen to your upper thigh.
HIP - MERALGIA PARASTHETICA - RISK FACTORS
- Obesity or weight gain
- Pregnancy
- Local trauma
- Diseases like diabetes
HIP - MERALGIA PARASTHETICA - CLINICAL PRESENTATION
- Patients may complain ofpain, burning, numbness, muscle aches, coldness, lightning pain, or buzzing (like a cell phone) in their lateral or anterolateral thigh
HIP - PROTRUSIO ACETABULI
- Condition of the hip where there is medial displacement of the femoral head into the pelvis and the medial aspect of the femoral head lies medial to the ilioischial line.
