Necrosis avascular de cabeza femoral tras osteosíntesis de fractura pertrocantérea con clavo gamma

This is a case study of a patient with a intertrochanteric femoral fracture treated by gamma nailing with favourable evolution for a period of one year that subsequently developed avascular necrosis of the femoral head. The possible cause is discussed and a good surgical fixation technique is recommended to prevent this outcome. It is advisable to consider this condition as a possible explanation for the long-term deterioration of a patient with good initial postoperative clinical results.
