Q

Slipped upper femoral epiphysis : Pathophysiology

A
  1. Adolescence during growth spurt:
    * Growth plate is a weak area where growth occurs
  2. Increased stress on the hip joint
    * Mechanical stress
    * Obesity
  3. Head of the femur slips and is displaced at the growth plate - posterior-inferiorly

Q

Perthes disease : Clinical features

A
  1. Hip pain : progressive over few weeks
  2. Limp
  3. Stiffness and reduced range of movement
20
Q

Perthes disease : Investigation

A

X-ray : Widening of joint space, decreased femoral head size/flattening

21
Q

Perthes disease : Management

A
  1. Supportive Casts/Braces : keeps femoral head within the acetabulum
  2. < 6 years : Observation
  3. Surgical management
    Most cases resolve with conservative management
22
Q

Developmental dysplasia of the hip : Definition

A

Congential disease which occurs when the hip joint does not develop properly in infants.

Presentation : Dysplasia to complete Dislocation of the hip joint

23
Q

Developmental dysplasia of the hip : Causes/Risk factors

A
  1. Female (more common)
  2. Breech presentation : legs in breech are extended and affect development of hip in utero
  3. Oligohydramnios : low level of amniotic fluid limits baby’s movement
  4. Genetics : Family hx
24
Q

Developmental dysplasia of the hip : Clinical symptoms

A
  1. Leg length discrepancy
  2. Level of knees when hips + knees are bilaterally flexed
  3. Restricted ROM : abduction of the hip in flexion
25
Developmental dysplasia of the hip : Clinical signs
* Barlow test: attempts to dislocate an articulated femoral head * Ortolani test: attempts to relocate a dislocated femoral head
26
Developmental dysplasia of the hip : Investigations
1. Screening; * New born check * 6 week baby check:  Barlow + Ortolani test 2. Ultrasound - if >5 months for X-ray
27
Developmental dysplasia of the hip : Management
1. Spontaneously resolve by 3-6 weeks 2. < 5 months : Pavllik harness
28
Chondromalacia patellae : Definition
Softening and degeneration of the underside of the knee cap
29
Chondromalacia patellae : Clinical features
1. Pain : * Surrounding or behind patella * Up/down Stairs : anterior knee pain * Pain around or behind knee * Pain after prolonged knee bending 2. Crepitus : When moving knee 3. Overuse/repetitve stress on the knee
29
Chondromalacia patellae : Incidence
Teenage girls
30
Chondromalacia patellae : Management
Physiotherapy
31
Osgood-Schlatter disease : Definition
1. Condition affecting sporty teenagers 2. Inflammation and pain at the tibial tuberosity
32
Osgood-Schlatter disease : Pathophysiology
1 . Tibial tuberosity * Has a growth plate * Patella tendon attaches to tibia 2 . Growth spurt * Bones and tendons grow at different rate * Increased tension on growth plate 3 . Pulling on patellar  tendon on the growth plate * Inflammation and pain
33
Osgood-Schlatter disease : Incidence
Athetic teenager : sports requiring flexion of the knees
34
Osgood-Schlatter disease : Clinical features
1. Pain below patella : tender tibial tuberosity, exacerbated by activity 2. Swelling and tenderness of tibial tuberosity
35
Patellar tendonitis : Definition
Inflammation of the patellar tendon causes by repetitive jumping/running or intense physical activity
36
Patellar tendonitis : Pathophysiology
1. Repetitve stress on tendon without adequate recovery time * Microscopic tears accumulate and cause inflammation
37
Patellar tendonitis : Clinical features
1. Anterior knee pain : below kneecap, where tendon attaches to tibia 2. Pain during and after activity 3. Tenderness and swelling of Patella tendon
38
Osteochondritis dissecans : definition
Triggered by chronic activity and causes by separation of cartilage and underlying bone
39
Osteochondritis dissecans : Pathphysiology
1. Repeated stress or trauma 2. Disruption of blood supply 3. Ischaemia, fragmentation and detachment * Necrosis : segment and underlying bone can become fragmented and detach from joint surface 4. Loose body formation * Detatched fragment may  remains within joint
40
Osteochondritis dissecans : Clinical features
1. Joint pain and swelling 2. Joint instability : catching and locking 3. Limited range of movement
41
Patellar subluxation : Definition
Partial dislocation of the patella from its position within the patellofemoral groove
42
Patellar subluxation : Incidence
Sporty children - high impact sport
43
Patellar subluxation :Clinical features
1. Instability / locking : knee may give away 2. Medial knee pain from lateral subluxation
44
Osteogenesis imperfecta : Definition
Autosomal dominant disorder - mutation of genes affecting synthesis of type 1 collagen
45
Osteogenesis imperfecta : Pathophysiology
* Bone fragility /high risk of fractures * Collagen is in the extra cellular matrix - contributes to bone strength * Abnormal bone formation : * Dysfunction collagen affects bone formation * Growth retardation
46
Osteogenesis imperfecta : Clincial features
1. Brittle teeth 1. Hypermobility 1. Blue sclera : thin and translucence of the scleral tissue which is caused by collagen abnormalities 1. Hearing loss : collagen is present in inner ear and abnormalities can cause hearing loss
