Origin: outer surface of inferior ramus of pubis; Insertion: on a line extending from lesser trochaner to linea aspera and proximal 1/4 of linea aspera; Action: adduction of the femur at the hip; lateral rotation as it adducts the thigh. some assistance to femur flexion at the hip; Nerve Supply: Obturator, L2, L3, L4; (See Innervation) Synergists: Gracilis, Pectineus
– Discussion: – 11% of cases – occurs following significant trauma, produces sudden onset of pain severe enough to prevent weight bearing; – pts usually report minimal or no previous symtoms; – Treatment: – reduction vs. traction: – gentle repositioning can reduce … Read more
Autogenous bone graft remains the most effective treatment for fracture non unions, pseudoarthroses and for optimizing the success rate of arthrodesis. It is safer and more effective than artificial hydroxyapatite materials or allograft. The Acumed bone graft harvesting instruments facilitates safe, rapid harvest of morsellized autogenous graft through a small skin incision which minimizes the … Read more
Clinical Presentation pts recounts h/o aching in hip, thigh, or knee (from chronic slip) along w/ h/o sudden severe pain (from concomitant acute slip); Treatment pin placement: reduction may be obtain by gentle skeletal traction in flexion & internal rotation; – forceful manipulation must be avoided.
(see also: 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 atrophy of the soleus muscle, and commonly occur in weekend athletes; in 5-33% … Read more
(see also: 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 have second achondroplastic child; it is presumed in these … 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
optimal graft angle the report by Howell SM, et al, the authors studied the angle of the tibial tunnel to graft function; 5 surgeons treated 119 subjects by reconstructing a torn ACL using a double-looped semitendinosus and gracilis graft and a standardized technique; radiographs were analyzed for tibial tunnel placement and a clinical evaluation was … Read more
