MSK Revision Flashcards
what is a back SPRAIN?
injury involving only ligamentous tissue, or the attachment of ligament to bone, without dislocation or fracture.
occurs with excessively strong contractions related to VC movements e.g. excessive extension or rotation.
what is a back STRAIN?
some degree of stretching or microscopic tearing of muscle fibres due to overly strong muscular contraction.
muscles often those producing movements of lumbar IV joints, especially the erector spine.
what is a muscle spasm?
a sudden involuntary contraction of 1 or more muscle groups.
attended by cramps, pain, and interference with function

why are adolescents at risk of osteochondrosis?
combined stress on epiphyseal plates not yet fused, resulting from physical activity and rapid growth of the bone which grows faster than the attached muscle in growth spurts, causing irritation and injury of the epiphyseal plates and developing bone.

where do avulsion fractures of hip bone occur?
where muscles are attached: ASIS, AIIS. ischial tuberosities and ischiopubic rami

what is coxa vara?
decreased angle of inclination between the long axis of the femoral neck and the femoral shaft
causes a mild shortening of lower limb and limits passive abduction of hip
what is coxa valga?
increased angle of inclincation between the long axis of the femoral neck and the femoral shaft.

what muscle of the thigh is often removed and used to replace damaged muscles e.g. in the hand?
gracilis
as relatively weak member of the adductors
can also be used to replace a non-functional external anal sphincter*
