Data Trace Editor – 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
– Discussion: – primary internal fixation is treatment of choice for unstable scaphoid frxs; – frx treated by primary internal fixation, avg time for return to work is 3.7 wks w/ union rate, 97 %; – this compares very favorably with conservative treatment; – indications for surgery: – main indication is an unstable scaphoid frx … Read more
– outcomes: – in the report by Saeden B, et al, the authors compared the long-term outcome in 61 patients (62 fractures) treated operatively or conservatively for an acute fracture of the carpal scaphoid; – total of … Read more

Discussion is preferred by many for use in older children and adolescents; skeletal traction is applied w/ Steinman pin inserted thru distal femur; see: insertion technique knee should be flexed 30 deg to relax the hamstrings; deformity: w/ mid shaft frx, there is tendency is toward posterior angulation; to restore the normal anterior bowing of … Read more
– Discussion: – fractures of the sustentaculum tali result from landing on the heel combined with severe inversion of the foot; – inversion of foot produces acute pain just below the medial malleolus; – pain may be accentuated by passive hyperextension of the great toe; – this fracture may be mistaken … Read more
– Discussion: – insert blunt Homan retractors superiorly & inferiorly to obtain exposure of entire superior, posterior, & inferior portions of capsule; – divide exposed portion of capsule along its attachment to femur; – make a longitudinal or T shaped extension of capsular incision along axis of femoral neck, directing incision … Read more
– Discussion: – bluntly split gluteus maximus proximally in direction of its fibers & coagulate any vessels w/in substance of muscle; – note that muscle does not have to be split in line w/ incision, but can be split in line w/ its fibers in a direction superior to skin incision; … Read more
