Data Trace Editor – See: – Plantar Muscles of the Foot: – Innerv. Musc. Lower Limb – Origin: – medial process of the calcaneus, central part of the plantar aponeurosis, and the intermuscular septa; – entire muscle belly is firmly united with the plantar aponeurosis; … Read more
– See: Plantar Muscles of the Foot: – Origin: posterior surface of middle 3/5 of tibia; – Insertion: branches into 4 tendons that insert the plantar surface of base of distal phalanx of the 4 lesser toes. – Action: – flexes phalanges at all phalangeal and metatarsophalangeal articulations of 2nd … Read more
– See: – Forearm Flexors – Swan Neck Deformity following Excision of FDS – FDS Laceration: – Anatomy: – origin: – humero-ulnar head: medial epicondyle of humerus by common tendon, ulnar collateral ligament of elbow & coronoid process of … Read more
– See: Plantar Muscles of the Foot: – Origin: – medial portion of the plantar surface of the cuboid bone, adjacent portion of the lateral cuneform bone and prolongation of tendon of tibialis posterior. – Insertion: – medial and lateral heads of the F.H.B. insert onto … Read more
– Anatomy: – origin: distal 2/3 of posterior fibula, interosseous membrane and adjacent intermuscular septum; (see deep posterior compartment) – tendon passes through posterior aspect of fibro-osseous tunnel, plantar midfoot (knot of Henry); – insertion: – plantar surface of base of distal phalanx … Read more

– See: – Chance Frx: – Fracture Dislocation: – Definition: – flexion distraction injuries may occur thru bone or soft tissue, and they may involve one or several levels; – flexion distraction injuries occur secondary to distractive disruption of posterior & middle columns w/ compression failure … Read more
– See: Lower Cervical Burst Frx: – Discussion: – most severe fracture of cervical spine – results from combination of extreme flexion & compressive forces – commonly results from a dive into a shallow pool of water; – associated w/ acute anterior cervical cord syndrome … Read more
Discussion: – 5-10% of all supracondylar frxs – occurs from fall w/ elbow flexed as it hits the ground; – posterior cortex fails first; – resulting frx has anterior displacement of the distal fragment in sagittal plane, and lateral/valgus displacement in coronal plane … Read more
– See: Forearm Flexors – Discussion: – origin: medial epicondyle of humerus; – anatomy at the wrist: – when pt flexes wrist & radially deviates his hand, tendon becomes prominent next to the palmaris longus; – FCR lies radial to the … Read more
