– Discussion: – Q angle is the angle formed by a line drawn from the ASIS to central patella and a second line drawn from central patella to tibial tubercle; – an increased Q angle is a risk factor for patellar subluxation; – normally Q angle is 14 deg for … Read more
– See: Phalangeal Injury Menu: – Discussion: – fractures of the proximal phalanx are potentially the most disabling fractures in the hand; – direct blows tend to cause transverse or comminuted frx, where as twisting injury may cause oblique or spiral fracture; – proximal fragments are usually flexed by intrinsics while distal fragments … Read more
