Isolated lesser trochanter fracture in adults: An early indicator of tumor infiltration

SummaryWe report on a case of isolated lesser trochanter fracture, without associated trauma, secondary to pulmonary adenocarcinoma metastasis. Treatment consisted in resection–reconstruction by megaprosthesis. This form of isolated fracture is rare, and results from infiltration of the trochanteric area by a malignant tumoral process, which is usually metastatic.
