Effect of Preoperative Nutritional Status on Postoperative Functional Recovery of Hip Joint in Elderly Patients with Intertrochanteric Fractures.

OBJECTIVE

The state of nutrition of senior patients with intertrochanteric fracture of femur before operation affects the patients' tolerance to the operation,the body recovery, healing of the wound and clinical prognosis. For these patients, the poor state of nutrition may lengthen the time of being in hospital, leading to poor hip recovery and clinical outcome. But currently, the relationship between functional recovery of hip joint after operation of intertrochanteric fracture in elderly patients and camp condition has not been reported. To investigate the effect of preoperative nutritional status on postoperative recovery of hip joint function in elderly patients with intertrochanteric fractures.

METHODS

Retrospective analysis was performed on the data of 96 elderly patients with intertrochanteric fracture of the femur treated with closed reduction PFNAfrom January 2021 to January 2022 in Dongying People's Hospital Trauma Orthopedics Department. There were 36 male patients and 60 female patients aged from 65 to 92.The patients were divided into the normal nutrition group (GNRI ≥ 92, n = 46) and the malnutrition group (GNRI < 92, n = 50). The general clinical data, time from injury to operation, intraoperative and postoperative allogeneic blood transfusion rate, postoperative complication rate, postoperative mortality 1 year, and Harris hip function score at 3, 6, 9 months and the last follow-up were compared between the two groups.

RESULTS

All patients were followed up for 9 to 15 months(mean,13.9 months) after surgery. The preoperative hemoglobin levels in the normal and malnutrition groups were 8.6-13.2 and 7.4-11.2 g/dL, respectively (P < .05). The time from injury to surgery in the normal nutrition group was significantly shorter than that in the malnutrition group (P < .01). The preoperative hemoglobin level in the normal nutrition group was significantly higher than that in the malnutrition group. The time from injury to operation in normal nutrition group and malnutrition group are respectively (1.1-5.2), (4.3-6.6)d; the intraoperative and postoperative allogeneic blood transfusion rates are respectively 47.8%(22/46), 92%(46/50);the incidence of postoperative complications are respectively 6.52%(3/46), 32%(16/50); the mortality rates within 1 year after operation are respectively 2.17%(1/46), 12%(6/50). In contrast, the postoperative allogeneic blood transfusion, postoperative complication, and postoperative complication rates in the normal nutrition group were significantly lower than those in the malnutrition group (P < .05). 3 months after surgery, the Harris hip function scores of patients in normal nutrition group and malnutrition group are respectively (75.26±4.02), (64.28±3.82); 6 months after surgery, the Harris hip function scores of them are respectively (80.42±3.86), (70.14±5.06).During the last follow-up, scores are (82.23±2.98), (72.12±4.62). At the 3, 6, and last follow-up after surgery, the Harris hip function score in the normal nutrition group was significantly higher than in the malnutrition group (P < .05).

CONCLUSION

Preoperative malnutrition in elderly patients with intertrochanteric fracture has adverse effects on postoperative hip function recovery, and 1-year postoperative survival rate.GNRI can be used for simple screening. Early assessment of patients' nutritional status.
