ObjectiveTo compare the therapeutic effect between intramedullary fixation and external fixation on intertrochanteric fracture. MethodsBetween June 2005 and June 2011, 32 patients with Evans-Jensen type Ⅲ intertrochanteric fracture were treated with proximal femoral nail anti-rotation (PFNA), Gamma nail, dynamic hip screw plate (DHS) or locking compression plate (LCP), separately. The operation duration, peri-operative bleeding, load time, Harris hip score and postoperative complications were observed in the patients, and were used to analyze the therapeutic effect among the four methods. ResultsShorter operation duration, less bleeding in the surgery, smaller quantity of drainage after the operation (P<0.05) were found in group Gamma and group PFNA compared with those in group DHS and LCP. The duration of hospitalization didn't differ much between the two fixation systems (P>0.05). The difference in operation duration, operative bleeding and post-operative drainage between group Gamma and PFNA, and between group DHS and LCP was not significant (P>0.05). ConclusionThe intramedullary fixation was better than external fixation for Evans-Jensen type Ⅲ intertrochanteric fracture.
Objective To compare the effectiveness of the proximal femoral nail anti-rotation (PFNA) and locking compression plate (LCP) in the treatment of intertrochanteric fractures with the lateral unsubstantial femoral wall in elderly patients. Methods Between May 2009 and August 2012, 69 elderly patients with intertrochanteric fractures with the lateral unsubstantial femoral wall were treated. Fractures were fixed with PFNA in 36 patients (PFNA group), and with LCP in 33 patients (LCP group). There was no significant difference in gender, age, injury cause, side of fracture, and fracture AO type between 2 groups (P > 0.05). The incision length, operation time, intraoperative blood loss, total blood loss, fluoroscopy frequency, time for ambulation, and early (within 3 months) and late (more than 12 months) complications were compared. Fracture healing was assessed according to X-ray reexamination, the function of the hip joint was assessed according to the Harris hip scoring system. Results The incision length, operation time, intraoperative blood loss, and time for ambulation of PFNA group were significantly less than those of LCP group (P < 0.05), but the fluoroscopy frequency of PFNA group was significantly more than that of LCP group (P < 0.05). There was no significant difference in total blood loss between 2 groups (t=-1.686, P=0.096). The patients were followed up 12-24 months in PFNA group and 15-30 months in LCP group. The X-ray reexamination revealed fracture healing at (12.667±2.527) weeks in patients of PFNA group, and at (13.364±1.194) weeks in the others of LCP group except 1 case of nonunion, showing no significant difference (t=-1.443, P=0.154). There was no significant difference in Harris hip score between PFNA group (84.611±7.076) and LCP group (81.785±7.500) at 12 months after operation (t=1.626, P=0.109). The early complication rate and late complication rate were 16.7% (6/36) and 5.6% (2/36) in PFNA group and were 9.1% (3/33) and 9.1% (3/33) in LCP group, all showing no significant difference between 2 groups (χ2=0.871, P=0.481; χ2=0.320, P=0.665). Conclusion Both PFNA and LCP have good effectiveness in the treatment of intertrochanteric fractures with the lateral unsubstantial femoral wall in the elderly patients. Each has its own advantages and disadvantages.
Objective To compare the effect of proximal femoral nail anti-rotation (PFNA) and dynamic hip screw (DHS) in the treatment of intertrochanteric fracture in elderly patients with osteoporosis. Methods A total of 72 elderly patients with intertrochanteric fractures were enrolled between December 2011 and December 2014. According to the different surgical methods, the patients were divided into PFNA group (38 cases) and DHS group (34 cases). The operation time, perioperative blood loss, postoperative weight-bearing time, Harris score were compared between the two groups. Results All cases were followed up for 5–24 months (mean, 13.5 months). The operation time in PFNA group was shorter than that in DHS group [(40.25±24.23) vs. (72.65±34.65) minutes], the perioperative blood loss in PFNA group was less than that in DHS group [(136±56) vs. (256±102) mL], the postoperative weight-bearing time in PFNA group was earlier than that in DHS group [(5.24±4.52) vs. (15.69±6.78) days], and the Harris score in PFNA group was higher than that in DHS group (80.23±10.26 vs. 54.75±12.37) ; the differences above were all statistically significant (P<0.05). Conclusion Elderly patients with intertrochanteric fracture and osteoporosis treated with PFNA have shorter operation time, less wounds, better hip function, and earlier weight-bearing than the patients treated with DHS; the surgical method can improve the patient′ life quality.
ObjectiveTo compare the effectiveness of long and short proximal femoral nail anti-rotation (PFNA) in the treatment of type A2.3 intertrochanteric fracture of femur (IFF). Methods The clinical data of 54 patients with type A2.3 IFF admitted between January 2020 and December 2022 were retrospectively analyzed. According to the length of PFNA nail used in the operation, they were divided into long nail group (PFNA nail length>240 mm, 24 cases) and short nail group (PFNA nail length≤240 mm, 30 cases). There was no significant difference in baseline data such as gender, age, fracture side, body mass index, and time from fracture to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, intraoperative reduction quality score, fracture healing, and complications of the two groups were recorded and compared. Harris score was used to evaluate the hip function of patients at 1 year after operation. According to the relationship between the fracture line of type A2.3 IFF and the lesser trochanter, the two groups of patients were divided into type Ⅰ(the fracture line extends to the level of the lesser trochanter), type Ⅱ(the fracture line extends to less than 2 cm below the lesser trochanter), and type Ⅲ (the fracture line extends to more than 2 cm below the lesser trochanter), and the postoperative stability and internal fixator loosening of each subtype were evaluated. Results The operation time, intraoperative blood loss, and intraoperative fluoroscopy frequency in short nail group were significantly less than those in long nail group (P<0.05). There was no significant difference in the intraoperative reduction quality score between the two groups (P>0.05). Patients in both groups were followed up 12-18 months, with an average of 13.5 months. The postoperative stability score of short nail group was significantly lower than that of long nail group (P<0.05). The Harris score in the long nail group was significantly higher than that in the short nail group at 1 year after operation (P<0.05), but there was no significant difference in Harris score grading between the two groups (P>0.05). Complications occurred in 3 cases of the long nail group (including 1 case of coxa varus caused by external nail entry point and 2 cases of loose internal fixator), and 7 cases of the short nail group (including 1 case of coxa varus caused by external nail entry point and 6 cases of loose internal fixator). Neither group had any anterior femoral arch damage, there was no significant difference in the incidence of complications between the two groups (P>0.05). The number of type Ⅲ patients was relatively small and not included in the statistics; there was no significant difference in the postoperative stability score and the incidence of internal fixator loosening between the long and short nail groups in type Ⅰ patients (P>0.05). In type Ⅱ patients, the postoperative stability score and the incidence of internal fixation loosening in the long nail group were significantly better than those in the short nail group (P<0.05).Conclusion Long PFNA fixation for type A2.3 IFF has longer operation time and more intraoperative blood loss, but the overall stability of fracture is better after operation. For type A2.3 IFF with fracture line extending to less than 2 cm below the lesser trochanter, long PFNA is used for fixation, although the surgical trauma is large, but the postoperative stability is better than that of short PFNA; for type A2.3 IFF with fracture line extending to the lesser trochanter, there is no significant difference in postoperative stability between long and short PFNAs.
