Objective
To investigate the difference in the effectiveness between proximal femoral nail anti-rotation (PFNA) and proximal femoral locking compression plate (PFLCP) for intertrochanteric fracture in elderly patients combined with hemiplegia due to cerebral infarction.
Methods
The clinical data of 67 cases of intertrochanteric femoral fractures combined with hemiplegia due to cerebral infarction between October 2013 and January 2017 were retrospectively analyzed. Among them, 32 cases were treated with PFNA internal fixation (PFNA group), and 35 cases were treated with PFLCP internal fixation (PFLCP group). There was no significant difference in gender, age, injury side, modified Evans classification of fracture, preoperative medical disease, and interval from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, postoperative bed time, incidence of perioperative complications, time of fracture healing, and hip Harris score at 6 months and 1 year after operation were recorded and compared.
Results
Both groups were followed up 12-24 months with an average of 14 months. Compared with the PFLCP group, the PFNA group had shorter operation time, less intraoperative blood loss, and shorter bed time, and the differences were significant (P<0.05). X-ray films showed that the fractures healed in both groups. The fracture healing time of the PFNA group was shorter than that of the PFLCP group, but the difference was not significant (t=0.743, P=0.460). During hospitalization, there were 3 cases of pulmonary infection, 2 cases of deep venous thrombosis of lower limbs, and 1 case of urinary tract infection in the PFNA group; and the incidence of perioperative complications was 18.8% (6/32). There were 4 cases of pulmonary infection, 6 cases of deep venous thrombosis of lower limbs, 1 case of recurrent cerebral infarction, and 1 case of stress ulcer in the PFLCP group; and the incidence of perioperative complications was 34.3% (12/35). There was no significant difference in the incidence of perioperative complications between 2 groups (χ2=2.053, P=0.152). At 6 months after operation, the Harris total score and individual scores in the PFNA group were higher than those in the PFLCP group (P<0.05). At 1 year after operation, there was no significant difference in the Harris total score and pain score, life ability score, and walking ability score between the PFNA group and the PFLCP group (P>0.05); However, the joint deformity and activity score of the PFNA group was significantly better than that of the PFLCP group (t=4.112, P=0.000).
Conclusion
For intertrochanteric fracture in elderly patients with cerebral infarction hemiplegia, the PFNA has shorter operative time, less intraoperative blood loss, shorter bed time after operation, and better short-term hip function when compared with the PFLCP.
Objective To compare the effects of cutting and retaining the pes anserinus tendon on effectiveness following tibial plateau fracture. MethodsA clinical data of 40 patients with tibial plateau fracture treated with open reduction and internal fixation with plate via posteromedial approach between January 2015 and January 2020 was retrospectively analyzed, including 18 patients retained the pes anserinus tendon (study group) and 22 patients cut the pes anserinus tendon (control group) during operation. There was no significant difference in gender, age, side of affected knee, cause of injury, Schatzker classification, time from injury to operation, and associated ligament injury between the two groups (P>0.05). The operation time, intraoperative blood loss, hospital stay, anatomic reduction rate, incidence of complications, fracture healing time, knee flexion and extension range of motion at 2 weeks and 12 months, and knee extension range of motion at 3 months after operation were recorded and compared between the two groups. The visual analogue scale (VAS) score was used to evaluate the early postoperative pain improvement at 1, 3, and 14 days after operation and hospital for special surgery (HSS) score was used to evaluate the improvement of knee function at 3, 6, and 12 months after operation. ResultsThe patients in both groups were followed up 12-15 months with an average of 12.8 months. There was no significant difference in operation time, intraoperative blood loss, and fracture healing time between the two groups (P>0.05). The hospital stay in the control group was significantly longer than that in the study group (t=8.339, P=0.000). There was no significant difference in the anatomic reduction rate (90.9% vs. 83.3%) between the control group and the study group (χ2=0.058, P=0.810). There were 1 case of proximal tibial osteomyelitis, 3 cases of skin necrosis, 3 cases of traumatic arthritis, and 2 cases of lower deep venous thrombosis after operation in the control group, and 1 case of metaphyseal nonunion, 2 cases of traumatic arthritis, and 1 case of lower deep venous thrombosis in the study group, showing no significant difference in the incidence of complications (40.9% vs. 22.2%) between the two groups (χ2=1.576, P=0.209). In the study group, knee flexion and extension range of motion at 2 weeks and 12 months and knee extension range of motion at 3 months after operation were significantly better than those of the control group (P<0.05). VAS scores and HSS scores in both groups improved with time after operation (P<0.05), in addition, the HSS score and VAS score of the study group were significantly better than those of the control group (P<0.05). ConclusionCompared with traditional pes anserinus tendon cutting group, pes anserinus tendon retaining group can significantly reduce postoperative short-term pain, improve postoperative knee range of motion and knee function within 1 year after operation.
