Synovium of the Knee
– See: – Bursae of the knee: – Pigmented Villonodular synovitis – Discussion: – synovial cavity is deepest layer of joint capsule & it often has several embryological invaginations called plica that persist into adult life; – these may cuase anterior knee symptoms, – although synovium membrane is attached all around, above to articular margins … Read more
Synthes Hybrid Circular Wire Fixator
– See: – Ring characteristics – Safe Zone of Pin Insertion – Foot Inclusion – Wire Insertion Technique – Case Example: – 25 year old male who sustained a gun shot wound to the tibia which resulted in an arterial trifurcation injury; … Read more
Synthes IM Femoral Nail Insertion Technique
– See: (Synthes Product Menu) – Reaming and Nailing Maneuver – Intramedullary Nailing – Miss A Nail Technique – Spiral Blade – Incision and Entry into Meduallary Canal – Proximal Inter-Locking – Distal Interlocking
Synthes Uniplanar External Fixator for Tibial Frx
– See: Synthes Hybrid Fixator – Discussion and Initial Considerations – Operative Technique: – may be combined w/ circular wire fixators; – reduction: – in most cases, the fracture should be reduced prior to fixator application; – planning the configuration: … Read more
Synthes Tibial Nail: Proximal Interlocking
– Engaging the Nail Jig: – position the insertion block on to the proximal end of the nail; – position insertion handle onto insertion block so it will be medial to tibia for nail insertion and precise placement of proximal locking; – note that the proximal nail tip … Read more
Syringomyelia
– See: Myelodysplasia: – Discussion: – syringomyelia is a condition in which tubular cavity, or syrinx, in central area of spinal cord gradually expands leading to progressive myelopathy; – it is associated w/ disturbed hydrodynamics of cervical spinal fluid w/ or w/o associated obstruction at the cranial cervical junction; … Read more
Synergistic Nonclostridial Anaerobic Myonecrosis
– similar to gas gangrene – dishwater pus may be present; – Bacteroides and/or anaerobic streptococci may be present, together with aerobic or facultative grm neg. bacilli; Necrotizing Fasciitis: – serious infection that spreads rapidly along fascial planes and is commonly caused by Staphylococcus aureus or Streptococcus pyogenes; – anaerobes – especially clostridia and bacteroides can … Read more
Synovial Chondromatosis
Discussion a monarticular synovial proliferative disease which is characterized by the metaplastic conversion of cartilagenous tissue to ossified loose bodies; cartilagenous or osteocartilaginous metaplasia takes place w/in the synovial membrane of joints, bursae, or tendon sheaths; seen most often in middle-aged men; pts report pain and limitation of motion; location over one-half of cases occur … Read more
Synovial Plica
– Discussion: – synovial plica are folds of embryonic remnants of synovial membrane which, in fetus, divide knee is divided into medial, lateral, & patellar compartments; – although these membranes normally degenerate by the second trimester, (allowing knee to become one cavity), incomplete membrane degeneration will lead to the formation of plica – Medial (Shelf) Plica … Read more
