What does bone loading lead to
-bone strain (bending)
What can bone strain potentially lead to
-bone damage -no damage
If there is no damage in the bone after bone strain, what happens
-bone tries to reinforce itself -affects tolerance for next loading segment
If bone is damaged from strain what happens
-damage related remodelling
What happens if there is damage to the bone and we do not appropriately modify load for patient
-stress fracture -complete bone fracture etc
What is the role of osteoclasts
-take damaged bone away from site
What is the role of osteoblasts
-to build new bone
What is a low risk bsi
-less likely to have problems with healing process
What is a high risk bsi
-more likely to have problems with the healing process
What are some examples of low risk bsi’s
-posteromedial tibia -fibula/lateral malleolus -femoral shaft -pelvis -calcaneus
What are some examples of high risk bsi’s
-femoral neck -anterior cortex of tibia -medial malleolus -talus -navicular -proximal diaphysis of 5th metatarsal -base of second metatarsal
What are the factors modifying load
-load applied to a bone -ability to resist bone loading
What are factors modifying the load applied to a bone
-biomechanical factors -training factors -muscle strength and endurance -training surfaces and terrain -shoes and inserts
What are some examples of biomechanical factors
-ground reaction force magnitude -running gait kinematics etc
What are some examples of training factors
-duration -frequency of sessions -intensity/speed
What are factors modifying the ability of bone to resist load
-genetics -diet and nutrition -endocrine status and hormones -physical activity history -bone diseases -medications influencing bone
What is an additional risk factor for bsi’s
-RED-S
What does RED-S stand for
-relative energy deficiency in sport
What is RED-S
-comprehensive model depicting a low energy status in physically active persons -affects athletes recovery from injuries
What are some effects of RED-S
-depression -irritability -decreased concentration -decreased coordination -impaired judgement -decreased training response -increased injury risk
What are the principles for bone rehabilitation
-relative rest -early mobilization -early strengthening
What does relative rest mean for a bsi
-avoid stressing injured tissue
Should there be any pain experienced during WB with bone rehab
-no
What should pain be on NRPS during, after and 24 hours after activity
-0/10
