– Anatomy: – origin: posterior gluteal line of the ilium, tendon of sacrospinalis, – dorsal surface of sacrum, coccyx and sacrotuberous ligament; – insertion: gluteal tuberosity of femur and iliotibial tract of fascia lata – it inserts partly into the … Read more
– Anatomy: – origin: – outer surface of ilium from iliac crest and posterior gluteal line above to the anterior gluteal line below, gluteal aponeurosis; – note that posterior border of the gluteus medius is almost in line w/ femoral shaft; the anterior border fans anteriorly; … Read more
– origin: – outer surface of ilium between anterior and inferior gluteal lines and margin of greater sciatic notch; – insertion: anterior border of greater trochanter; – action: – abducts femur at the hip and rotates it medially; – lateral pelvic stabilizer; … Read more
– Discussion: – arises from L1 and L2; – in abdomen, it descends on anterior surface of Psoas and then divides into genital and femoral branches; – genital branch innervates cremaster muscle and gives twigs to scrotum and adjacent thigh; – femoral branch passes under inguinal ligament & … Read more
– Discussion: – medial and lateral muscle bellies each carry long flaps of skin and fascia from the posterior calf and are most often used as myocutaneous flaps; these flaps are most useful for upper tibial defect reconstruction; – Contra-indications: – knee dislocation or … Read more
– See: external rotators of the hip: Origin: the outer surface of the spine of the ischium Insertion: the posterior medial surface of the greater trochanter on the femur; Action: external rotation of the femur at the hip; Nerve Supply: sacral plexus, L5, S1, S2; (see innervation) Synergists: piriformis, obturator externus, obturator internus, quadratus femoris, … Read more
– See: DDH – Discussion: – indicated for residual dysplasias in adolescents and young adults; – allows both anterior and lateral rotation as well as medialization of the hip; – can expect good improvement in the center edge angle (avg correction of 31 deg); – does not … Read more
– See: – Achilles Tendon: – Gastrocnemius Flap: (see reconstructive surgery for the leg): – Anatomy: (see superficial posterior compartment); – origin: – lateral head: lateral condyle and posterior surface of femur; – medial head: medial condyle … Read more
– Discussion: – frx of radial shaft (between middle and distal 1/3’s) & dislocation of distal radioulnar joint; – usually the dislocation is dorsal, but in some cases can be palmar; – frx is almost always … Read more
