Strain

– See: – Elastic strain: – Biomechanics: – Discussion: – change in linear dimensions of a body resulting from the application of a force or load; – strain energy is the energy a body is capable of absorbing by changing its shape under the application of … Read more

Steel

– Discussion: – involves Salter osteotomy + osteotomy of both rami which results in placing articular cartilage over femoral head; – indicaitons: – older children w/ residual dysplasia & subluxation in whom there is minimal potential for remodeling; – older children w/ DDH since … Read more

Staph epidermidis

– Discussion: – is a coagulase negative, gram positive organism; – has emerged as one of the most common organisms in total joint infections (and in other implanted devices); – it is often minimally toxic (as compared to other bacterial infections), and many patients will have minimal symptoms of infection; … Read more

Stance Phase of Gait

– See: – Gait Menu: – Orthotics for the Foot – Discussion: – stance phase represents about 60% of the gait cycle, swing 40%; – normal gait is symmetric & thus, relationship between swing and stance phases of each leg are consistent; … Read more

Staph aureus

– Discussion: – is a coagulase positive, gram positive organism (as opposed to coag neg s. epidermidis) – has a strong propensity to invade traumatized tissue; – often responsible for toxic shock syndrome and necrotizing fascitis; – serious infection that spreads rapidly along fascial planes and … Read more

Staged Revision for Infected Total Knee Joint

– see 2 stage hip spacer – Discussion: – staged revision w/ antibiotic spacer: (see antibiotics in cement and local antibiotic delivery for septic joints) – debridement of components is followed by 6 weeks of IV antibiotics; – it is essential that all foreign material including cement be … Read more

Stage IV

– Discussion: – this is terminal phase of necrotic process, and is characterized by progressive loss of articular cartilage & development of acetabular osteophytes; – radiographic picture is of OA superimposed on a deformed femoral head; – movement is diminished until only a small range of flexion remains

Stage II Supination Inversion Injury

– Discussion: – involves injury to distal tibial ephiphysis, & are due to plantar hyperflexion or external rotation force; – presents as SH II, SH III, or SH IV type injury of distal tibia which may disrupt articular surface as well as physis; – Salter Harris III: … Read more

Stage III

– Discussion: – this stage is characterized by pathognomonic appearance of sequestrum on the radiograph; – this appearance is often preceded by changes representing a transition between stage II and III; – these are crescent line due to subchondral frx, & segmental flattening of femoral head; – sequestrum later becomes … Read more
