– Discussion: – decreased neck shaft angle from defect in ossification of femoral neck; – it is bilateral in 1/3 to 1/2 of cases; – it can be congenital (noted at birth & differenitated from CDH by MRI), developmental (AD-progressive), or acquired (trauma, LCP, SCFE) – Differential Dx: … Read more
Discussion if PaO2 and pH are within normal limits and PaO2 is about 100 mm but only w/ a high FiO2 or on therapeutic levels of PEEP, pt should be left to breath spontaneously with therapeutic PEEP; this is termed CPAP: continuous positive airway pressure; as arterial oxygenation improves, PEEP can be reduced in small … Read more

– Facial Fractures and Upper Airway Injuries: – in pts with major frxs of the mandible and maxilla (Lefort III) in whom massive edema has yet to occur, oral intubation is preferred, and if required is usually easily accomplished; – blind nasal intubation following major facial injury is discouraged because of … Read more

– Discussion: – in skeletally immature pt, isolated posterior arthrodesis w/ instrumentation of a lordotic curve may act as a posterior tethering bar, producing lordosis & bending of the fusion mass as the unfused anterior vertebral bodies continue to grow; – in the study by Noordeen MHH, … Read more
– Discussion: – for fixation of small bones such as forearm, fibula, & clavicle; – core diameter of 2.4 mm and requires a 2.5 mm drill bit; – 3.5 mm titanium shaft screw used as lag screw in a LC-DCP 3.5 mm – designed … Read more
– Discussion: – most common type of navicular frx; – caused by a twisting force (usually eversion) applied to the foot; – acute eversion of foot, resulting in increased tension on posterior tibial tendon or anterior fibers of deltoid ligament, places avulsion pull on navicular tuberosity, producing this fracture; … Read more
