– used to evaluate the extent of ligament injury to the A-C joint – Technique: – patient is erect; – 10 to 20 pound wts (depending on patient size) are looped over the patient’s wrists suspending them from the wrists; – these are not to be griped by the … Read more
– See: Achilles Tendonitis – Discussion: – ruptures typically occur after age 30, more often in people beyond middle age; – rupture at musculous tendinous junction occurs most often in young people, but ruptures near the calcaneus also occur; – inciting event may be related to … Read more
– Exam Findings: – note that active plantarflexion may occur due to activity of tibialis posterior, peroneals, and long toe flexors; – diagnosis is clinched w/ one of two tests; – hyper-dorsiflexion sign: – the patient is … Read more
– See: Achilles Tendonitis – Discussion: – indications: – may be indicated in older patients w/ minimally displaced ruptures; – note that younger patients w/ expectations of participating in sports such as basketball may not be good candidates for non operative rx; … Read more
– See: Pseudoachondroplasia – Discussion: – autosomal dominant disorder; – arises due to a point mutation for the gene encoding a fibroblast growth factor (Fibroblast growth factor receptor 3) – over 80% of all persons with this disorder are born to parents who are not achondroplastic, & such parents rarely … Read more
– Normal Hip Development: (limb development and pediatric anteversion); – at 4 to 6 gestational weeks, the hip joint develops from the cartilaginous anlage; – by 7 weeks a cleft develops between precartilagenous cells which are programmed to form the femoral head and acetabulum; – by 11 weeks, the hip … Read more
– Graft Entry Point: – because the slope of the intercondylar notch will vary from 26 to 44 deg, the tibial tunnel should be accordingly positioned between the anterior third and the midpoint of the saggital length of the tibia; – referenced off the PCL: – this … Read more
– Determination of Graft Length: – if a “two incision – backdoor” technique is used, it is usually not necessary to measure graft length; – whether the graft is slightly long or slightly short, it is usually very easy to move the graft slightly proximally or distally (through both … Read more
– See Rotator cuff; – origin: infraspinatus fossa of scapula – insertion: posterior aspect of greater tuberosity of humerus, capsule of shoulder joint; – demensions: infraspinatus has been shown to average 29 mm wide, with a mean medial-to-lateral width of 19 mm – action: extension, horizontal extension and lateral rotation of humerus at the shoulder … Read more
– Technique Considerations: – following restoration of fracture anatomy, contour 1/3 tubular, 3.5 pelvic reconstruction, or 3.5 DCPs, to fit medial and lateral aspect of distal humerus; – the strongest bone lies along medial and lateral columns and therefore the plate screws should be placed here rather than central portion of distal end of the … Read more
