Discussion: – oblique diaphyseal osteotomy that is directed proximal-plantar to distal-dorsal; – long dorsal shelf of bone supports the distal fragment, making dorsal displacement of the osteotomy unlikely; – type of intrinsically stable metatarsal osteotomy (weightbearing on the foot compresses the osteotomy) – other types of intrinsically stable osteotomies include the proximal … Read more
– See: – Congenital Deformities of the Hands: – Discussion: – rare anomaly – absence of digit, w/ cleft hand (“lobster claw” hand); – phalanges of middle finger, & sometimes corresponding metacarpal, are absent, & cleft in the plane of the missing digit & metacarpal separates … Read more

– Discussion: – at wrist, Lister’s tubercle is palpable on dorsum of radius; – it serves as a pulley for the EPL; – radial and ulnar styloid processes are also palpable, w/ tip of radial styloid process projecting 1 cm distal to that of ulna; – on … Read more
– See: Midfoot/Forefoot Fractures – Discussion: – anatomy of the midfoot – mechanism: – because 2nd metatarsal is the longest metatarsal proximally, it will often be frxed at its base, with the other metatarsals dislocated; – dorsal capsule of Lisfranc’s joint, lacking sufficienct reenforcement, will to support the load and will collapse, resulting in dorsal … Read more
– See: – Anatomy of the Physis – Deformities – Enchondral Ossification – Longitudinal Growth: – Pediatric Bone Circulation – Salter Harris – Discussion: – at about the 4th week of development, paired upper and … Read more
– Discussion: – see: limb development and physeal anatomy; – leg length discrepancy leads to awkward gait, & pelvic obliquity. – treatment of limb length inequality, requires an ability to predict leg length discrepancy at skeletal maturity; – differential diagnosis of limb length inequality – … Read more
– Volar Wrist Ligaments: – ligaments of wrist are most highly developed on palmar side of wrist; – palmar wrist ligaments originate laterally from radial styloid, & are directed in a distal ulnar direction; – intrinsic ligaments: – radial ligaments arise on palmar facet of radial styloid passing on to capitate; – ulnar sided intrinsic … Read more
Case Example by Dr. James R. Urbaniak MD – Discussion: – indicated for patients with basal joint arthritis or CMC instability; – LRTI involves partial or complete resection of the trapezium and recreation of the palmar oblique ligament using the distally based radial half of FCR to reconstruct ligamentous support for the metacarpal; – … Read more
Co-authored by: Jan Van Der Bauwhede MD – Discussion: – disorder of unknown etiology characterised by local proliferation of abnormal fibrous tissue in the plantar fascia – this tissue is locally aggressive and progressively replaces the normal plantar aponeurosis – this leads to often painful thickened fascia with nodules … Read more
