Document Summary

4 main joints: sternoclavicular, acromioclavicular, glenohumeral, scapulothoracic, movements & trade-off between mobility & stability depends on the articulation between the joints. Important to understand type of injury & how the muscles were involved etc. I. e. muscles usually provide a function such as providing stability & to move the arm it(cid:495)s. )f you don(cid:495)t have force couple or appropriate co-activation of ghj muscles humeral head causes excessive movement inside the glenoid fossa & acts as a (cid:498)wrecking ball(cid:499) Is a matter of skeletal changes not flexibility changes (so stretching will not fix it!: usually see humeral torsion only on throwing side see high stresses on bone due to. Swimming: you see retrotorsion in bone due to twisting forces, over time, prior to puberty, there can be longitudinal axis rotation which causes retrotorsion & therefore >80-90 degrees in the bone angle. Relevant for case study defense muscles )nvolved )n mvt(cid:495)s. From any direct trauma, damage many internal structures.
