Week 6 Flashcards
Describe the bone anatomy?
Cortical - outer compact bone, cylindrical shape, dense\
Trabecular - inner spongy bone, porous, honeycomb like, holes filled with marrow
What is bone remodelling?
New bone tissue formed to replace/ remove old bone tissue
What are osteoblasts?
Cells that build + strengthen new bone
What are osteoclasts?
cells that remove + resorb old bone
What is Wolffs law?
bone grows/ remodels in response to forces and demands
What are the 6 types of bone fractures and describe them?
Transverse - horizontal fracture
Oblique - Diagonal fracture
Spiral - Fracture that spirals around the bone
Comminuated - Shattered
Avulsion - Bone attached to tendon is pulled away from main bone
Impacted - Broken ends of the bone are jammed together
What are the 4 stages of bone healing?
Hematoma formation
Callus Formation
Callus Ossification
Bone remodelling
What are internal and external stressors and give some examples?
Internal stressors are within the body - HR or RPE
External stressors are outside the body - distance, duration, reps, weight
What is the acute:chronic work load?
Acute load (week)/chronic load (4 weeks) Sweet spot is 0.8-1.3
How does a lumbar stress fracture occur?
Overuse injury, low back pain L5+4 localised to one side. Pain through lumber extension, side flexion and rotation.
What is femoroacetabular impingement?
Abnormalities of the acetabulum or head of the femur which causes damage to the soft tissue to surrounding hip structures.
CAM - bony growth anterior/superior neck of femur
Pincer - growth of the socket = deep socket
Describe shin splints.
Pain along the posterior medial border of tibia, usually subsides with warm up.
What is a navicular stress fracture?
a fracture usually in the middle third of the navicular bone.
What is a navicular stress fracture?
a fracture usually in the middle third of the navicular bone.
