[A femur head preserving osteosynthesis procedure in para-articular femoral fracture of the hip in cardiopulmonary at-risk patients].

A series of 224 patients with fractures near the hip joint underwent internal fixation with conservation of the femoral head. Between January 1983 and December 1987 the operations with conservation of the femoral head were performed with Ender pins and Böhler nails. From January 1988 to December 1988 dynamic hip screws (DHS) were used exclusively for conservation of the femoral head. The patients were divided into three risk groups by preoperative cardiac and pulmonary risk score. In a retrospective study we compared different osteosyntheses for lethality, complications and duration of stay in hospital. The lethality with DHS was lower in risk groups II and III. The complication rate was significantly lower (P less than 0.05) in the group with DHS. The duration of hospital stay was significantly shorter (P less than 0.001) in the group in which DHS were used.
