We describe a 62-year-old woman who developed two pseudocysts, 25 × 15 cm and 20 × 12 cm, in the left proximal thigh as a complication 19 years after internal fixation of an intertrochanteric fracture. She received a 135° dynamic hip screw and side plate in May 1979. She continued to live at home without major discomfort until May 1997. Two huge pseudocysts were noted in the left proximal thigh without trauma history. Angiography was normal. Computerized tomography scan revealed two voluminous cystic lesions without septa in the left proximal thigh, with accumulated fluid. During surgery, two huge cysts were found in the left proximal thigh, and their orifices were found slightly proximal to the curvature of the side plate. The pathology showed that the cysts consisted of a nonepithelialized wall of granulation tissue compatible with a pseudocyst. The patient had no further problems 2 years after surgery. We found no reports in the literature of this rare complication. The development of the pseudocysts may have been the result of chronic low-grade trauma due to irritation between the soft tissue and the implant. Orthopedic surgeons should be aware of the possible development of this rare complication following internal fixation of an intertrochanteric fracture.
