– Discussion: – AC joint is situated between the clavicle and acromion; – acromion has two ossification centers which fuse at age 22 yrs; – it permits motion in three planes: – AP gliding of acromion during protraction & retraction of scapula; … Read more
– 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
