– See: Plantar Muscles of the Foot Origin: 2 heads, the medial surface and the lateral border of the inferior surfaces of the calcaneus; Insertion: fuses with the tendon of the flexor digitorum longus; Action: flexes the 2nd to 5th toes; Nerve Supply: Lateral plantar, S1, S2; (See … Read more
– arises from T12, L1, L2, L3, {L4}
origin: iliolumbar ligament, posterior part of the iliac crest; insertion: inferior border of the first rib and transverse process of the upper 4 lumbar vertebrae; action: pure lateral flexion of lumbar vertebral column; helps action of the diaphram in inspiration; nerve supply: Lumbar Plexus, T12, L1, L2, L3
– See: external rotators of the hip: Origin: superior aspect of external border of the tuberosity at ischium; Insertion: superior aspect of the linea quadrata, the line which extends downward from the intertrochanteric crest of femur; Synergists: piriformis, obturator externus, obturator internus, gemellus superior, gemellus inferior; Action: external rotation of the femur at the hip; … Read more
– Discussion: – multiple approaches can be used, but a medial approach is easiest w/ knee in extension as the patella can be rocked up anteriorly to aid in entry; – if pt will allow the knee to be flexed to 45 deg., then do so; – palpate the inferomedial and inferolateral borders … Read more
Discussion short sature beomes evident in early childhood; other manifestations of disorder (enlarged skull, short & broad hands & feet, dstrophic nails, and blue sclerae) usually are recongnized in infancy; pathologic fractures are a frequent complication; on x-ray, bone sclerosis appears during infancy
– Discusison: – not to be confused w/ pyogenic granuloma – poorly understood papulovesicular skin disorder involving ulcerations and necrosis which usually occurs along w/ an underlying systemic disease; – concomitant ulcerative colitis occurs in 30 – 60% of infected patients; – other … Read more
– Discussion: – Q angle is the angle formed by a line drawn from the ASIS to central patella and a second line drawn from central patella to tibial tubercle; – an increased Q angle is a risk factor for patellar subluxation; – normally Q angle is 14 deg for … Read more
– Discusison: – lesion should not be confused ith pyoderma gangrenosum; – it is not primarily a true infection; – an acquired vascular lesion lesion which may follow a laceration or skin puncture; – lesions may be found in oral mucosa and in the hands; … Read more
