Excessive Sliding of the Helical Blade and the Femoral Neck Fracture after Insertion of Proximal Femoral Nail Anti-Rotation for Type A2 Intertrochanteric Fractures - A Case Report -

Proximal femoral nail anti-rotation (PFNA) with a lag screw that is shaped like a spiral blade shape is an orthopedic implant to fix trochanteric fractures of the proximal femur. In addition the reason of the biomechanical advantages, PFNA widely been used recently. We report an 83-year-old man with excessive sliding of the helical blade and a femoral neck fracture after AO/OTA type A2 intertrochanteric fracture, which was fixed with a PFNA.

Necrotising Fascitis of the Thigh through Short External Rotator Muscles Due to an Unrecognized Perforated Rectal Cancer / 대한고관절학회지

Necrotizing fasciitis is one of the few true emergencies in orthopedic surgery that has a very high mortality rate unless recognized promptly and treated aggressively. The authors report a case of a patient with necrotizing fasciitis on the thigh that developed secondary to an unrecognized rectal cancer perforation through the short external rotator muscles. Clinicians should always be alert to the potential that rectal cancer perforations can cause necrotizing fasciitis in rare cases.
