– See: Soft Tissue Tumor Menu – Discussion: – 4th most common soft-tissue sarcoma (5 to 10 percent of all cases of soft-tissue sarcoma) – tumor derived from the synovial tissues found along fascial planes, periarticular structures, and rarely, in joints; – it may involve the … 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

– 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
– 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: – 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
(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: 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
