Data Trace Editor – 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
– See: Technique of Snydesmotic Fixation – Discussion: – if only syndesmotic ligaments are divided (w/ fibula & collateral ligaments intact) there will be no widening of mortise or lateral displacement of talus; – compressing the fibula and tibia above the ankle elicits tenderness at the syndesmosis, implies injury to the … Read more
– See: syndesmotic sprain – Anatomy: – syndesmosis is made up of anterior-inferior tibiofibular ligament, interosseous ligament, and posterior-inferior fibular ligaments, inferior transverse tibiofibular ligament, and interosseous ligament; – these stabilize the mortise by opposing the fibula in the fibular notch (incisura fibularis tibiae); – section of the anterior tibiofibular ligament results in diastasis of … Read more
– Acrosyndactyly; – Delta Phalanx; – Poland’s syndrome: – hypoplasia of hand and simple syndactyly of fingers on the same side as the absent pectoral muscles (and other chest wall muscles); – Apert’s Syndrome: – when all digits are … Read more
– See: Acrosyndactyly; – Discussion: – failure of differentiation of the tisses between the fingers at 5th-8th week of intrauterine life (see limb development); – most common in the middle and ring fingers; – syndactyly (webbing or fusion of two or more digits), a result of failure of … Read more
– Discussion: – includes ankle disarticulation, removal of malleoli, & anchoring heel pad to the wt bearing surface) allows execellent gait with a cosmetic prosthesis; – symes amputations will not heal w/o palpable posterior artery pulse; – surgery may be performed in 2 stages; – most common … Read more
– Discussion: – caused by non hemolytic Strep and hemolytic Staph aureus; – although staph alone may show up on culture, special attention may must be paid to isolating the microaerophilic Streptococceae; – necrotizing fascitis may occur, especially in diabetics; – any hand infection that does not respond … Read more
– See: Gait Menu: and Muscle Activity During Gait – Discussion: – during swing, the ankle dorsiflexes by the concentric contraction of anterior tibialis muscle; – all other muscles are silent; – momentum generated by the gastrocsoleus and hip flexors at terminal stance carries the leg forward – during initial swing … Read more
(1) full passive movement of the PIP Joint; – functional loss in these pts is related to loss of DIP joint extension; – consider flexor synovectomy, intrinsic release, FDS tenodesis, dermadesis, retinacular ligament reconstruction or DIP arthrodesis (to correct primary mallet finger deformity); (2) restriction of PIP flexion depending on MCP position … Read more
– See: – Phalangeal Injury – Thumb Swan Neck Deformity – Transverse Retinacular Ligament – Discussion: – deformity involves hyperextension of PIP Joint w/ flexion of DIP joint; – deformity may start at either the PIP or DIP; – at PIP joint, there … Read more
