Soleus

– See:      – Blood Supply of the Soleus:      – Soleus Muscle Flap:      – Superficial Posterior Compartment: – origin:         – posterior surface of the head and upper 1/3 of the shaft of the fibula;         – middle 1/3 of the medial border of … Read more

Soleus Muscle Flap

– Discussion:  – soleus is a bipiniform (double feather) shaped muscle;  – its width encompasses the posterior two thirds of the calf;  – it originates from the upper one third of the dorsum & medial surface of the fibula and mid-posterior tibia;  – it inserts into the achilles tendon over a 5 cm area just … Read more

Somites

– See: limb development – Discussion:     – skeleton and skeletal muscle develop from the mesoderm;           – thin layer of cells in early embryo located between ectoderm & endoderm & interrupted in midline by notochord;     – mesoderm on either side of notochord forms longitudinal mass, paraxial mesoderm; … Read more

SORBITOL

– for constipation; bowel prep;  – mixed with Kayexalate to prevent fecal impaction and aid in elimination of potassium in cases of hyperkalemia;  – osmotic / emollient laxative;  – dose: 30-60ml of a 20-70% solution prn;  – useful laxative with renal failure

Space of Poirier

– See:     – Ligaments of the Wrist – Discussion:     – an atomical defect or weak spot in the floor of the carpal tunnel;     – it lies at the volar aspect of the proximal capitate, lying between the volar radiocapitate and volar radiotriquetral ligaments (see ligaments);     – area expands … Read more

Smith’s Fracture

– See:        – Barton’s Fracture – Discussion:      – extra-articular palmarly displaced distal radius frx;      – volar angulation of frx is referred to as “Garden Spade” deformity (reversed Colles Fracture);      – hand & wrist are displaced forward or volarly w/ respect to forearm;      – frx may … Read more

Snake Bite Wounds

– See: necrotizing fascitis – Discussion:     – snake bite resources     – snake types:          – pit vipers (crotaline) which include rattlesnakes, cottonmouths, and copperheads;                – crotalus (rattlesnakes)                – agkistrodon (copperheads, water moccasins)                – micrurus … Read more

Sodium Fluoride

– Discussion:     – stimulates osteoblasts directly;     – in dosages of 40-80 mg per day, Na fluoride can increase trabecular-bone density of the axial skeleton substantially but does not increase cortical-bone density in the appendicular skeleton;     – concurrent calcium administration prevents or minimizes the mineralization defect that may occur when fluoride … Read more

Sodium Polystyrene Sulfonate/Kayexalate

– Discussion:  – is a potassium removing resin, for hyperkalemia;  – works as cation exchange resin, Na for K;  – because of its delayed action, a cation exchange resin such as sodium sulfonate should be used only in mild cases of hyperkalemia or in catabolic patients with continuous release of intracellular potassium;  – Precautions:  – … Read more
