Data Trace Editor – See: – Discoid Meniscus:: – Types of Meniscal Tears; – Discussion: – in shape medial meniscus resembles a C, whereas lateral meniscus is more sharply curved and resembles an O that is unclosed medially; – lateral meniscus is much more of closed circle in uniform width from anterior to posterior; – it has … Read more
– Discussion: – may position frame laterally if its cross bars are made of carbon (radiolucent); – disadvantage: relatively weak stabilization in AP plane; – if two pins are used at metaparpal level, 6 cortices are obtained by distal pin capturing two cortices & more proximal pin … Read more
– Anatomy: – LFCN, as its name suggests, is purely sensory; – it arises from L2 and L3, travels downward lateral to the psoas muscle, crosses the iliacus muscle (deep to fascia), passes either thru or underneath the lateral aspect of the inguinal ligament, and finally travels onto innervate the lateral … Read more
– See: Hallux Valgus Arthroplasty Menu: – Technique: – begins thru a short dorsal incision in 1st web space, which is made in midline in order to avoid superficial branches of deep peroneal nerve which passes on each side; – if incision is made to proximally, it … Read more
– Discussion: – arises from anterior division of upper (C5, C6) & middle trunks (C7); – lateral pectoral nerve – musculocutaneous nerve – lateral root of the median nerve : (FCR & pronator teres) and (sensory fibers to the median nerve) – lateral cord branches … Read more
– Discussion: Anterior Lesion: – lateral compression injury, contralateral type (Bucket Handle): – bucket handle type of injury is usually caused by direct blow to pelvis; – anterior fracture may be on the opposite side to the posterior lesion (contralateral type) or all four rami may fracture anteriorly; … Read more
– See: Pelvic Fractures – Discussion: – most common form of pelvic fracture; – transverse frx of pubic rami & ipsilateral / contralateral to posterior injury; – LC injuries are described by both their anterior and posterior pathology; – pelvic ring implodes or collapses, & one side rotates … Read more
– Discussion: – most severe form of Lateral Compression (Type III) is severely unstable
– Discussion: – its the most common pelvic fracture pattern; – involves compression injury to sacrum, w/ cancellous impaction; – sacral injury is often not identified & frx pattern is often misidentified as isolated pubic ramus frx; – sacral compression frxs are usually … Read more
– Discussion: – tripled layered arrangement on the lateral aspect of knee; – posterolateral part of capsule is divided into two laminae that encompass LCL, fabellofibullar, & arcuate ligaments; – Layer I – superficial Layer (Layer I): 2 parts; – iliotibial tract (and its expansion anteriorly) … Read more
