ObjectiveTo compare the clinical effect of proximal femoral nail antirotation (PFNA) and locking proximal femoral plate (LPFP) for femoral intertrochanteric fracture in elderly patients. MethodsWe respectively analyzed the clinical data of 116 senile patients with femoral intertrochanteric fracture treated between October 2008 and March 2014. Among them, 60 were treated with PFNA, and 56 were treated with LPFP. We compared the two groups of patients in terms of operating time, surgical blood loss, surgical complications, walking exercise time, fracture healing time and joint function recovery. ResultsA total of 115 patients had regular follow-up from 12 to 24 months (averaging 15.7 months). One patient died. The operating time was (83.26±14.81) minutes in PFNA group and (102.58±15.31) minutes in LPFP group. The surgical blood loss was (202.16±33.14) mL in PFNA group and (255.80±45.92) mL in LPFP group. The walking exercise time was (1.80±0.91) weeks in PFNA group and (3.48±3.03) weeks in LPFP group. The fracture healing time was (11.80±2.26) weeks in PFNA group and (12.14±2.21) weeks in LPFP group. The postoperative Harris score for hip joint was 84.56±9.55 in PFNA group and 82.47±9.22 in LPFP group. There were statistical differences in operating time, surgical blood loss and walking exercise time (P<0.05), while no statistical differences were found in fracture healing time and postoperative Harris score for hip joint (P>0.05). ConclusionPFNA and LPFP are effective methods for femoral intertrochanteric fracture in elderly people, but PFNA has a shorter operating time, less surgical blood loss and earlier walking exercise time.
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 proximal femur nailing and hemiarthroplasty in the treatment of intertrochanteric femur fractures in the elderly. Methods The study included 60 patients at the age of 75 or above who were diagnosed with intertrochanteric femur fracture between January 2011 and December 2013. After informed consent was obtained from the patients, they were randomized into two groups. Patients in internal fixation group (n=35) were internally fixated with proximal femoral nail, while patients in hemiarthroplasty group (n =25) were treated with cemented hemiarthroplasty. Complications, surgery time, hospital stay, postoperative function and blood loss during the surgery were recorded and functional results were evaluated using Harris Hip Score. Results Blood loss in the internal fixation group and the hemiarthroplasty group was respectively (124.7±23.4) and (207.5±19.4) mL, and the surgery time was (41.7±8.1) and (64.2±7.3) minutes, and the differences were significant (P<0.05). There was no significant difference in terms of complications between the two groups (P>0.05). Harris Hip Score analysis revealed that the difference between the patients treated with hemiarthroplasty and proximal femoral nailing was statistically significant in favor of the hemiarthroplasty group within the first 3 months. However, this difference diminished at the 6th month time point (P>0.05), and even reversed at the 12th month postoperatively (P<0.05). Conclusions Internal fixation with proximal femoral nail displays a better level of activity in the end in the treatment of intertrochanteric femur fractures. It is helpful for the patients to improve their life quality with convenient operation and less invasion.
ObjectiveTo compare the efficacy of proximal femoral nail anti-rotation (PFNA), locking compression plate (LCP), and artificial femoral head replacement for femoral intertrochanteric fracture in aged patients so as to provide reference for clinical treatment.MethodsA retrospective analysis was made on the clinical data of 150 aged patients with femoral intertrochanteric fracture treated between September 2009 and March 2016. PFNA was used in 51 cases (group A), LCP in 53 cases (group B), and artificial femoral head replacement in 46 cases (group C). There was no significant difference in sex, age, side, cause of injury, injury to operation time, type of fracture, and combined medical diseases between groups (P>0.05). The incision length, operation time, intraoperative blood loss, time for full weight bearing, hip Harris score, and complications were recorded and compared between groups.ResultsThe patients were followed up 12-23 months (mean, 18.6 months) in group A, 12-25 months (mean, 19.0 months) in group B, and 12-24 months (mean, 18.9 months) in group C. The incision length, operation time, and intraoperative blood loss of group A were significantly less than those of groups B and C (P<0.05); the operation time of group C was significantly shorter than that of group B (P<0.05), but there was no significant difference in incision length and intraoperative blood loss (P>0.05). The time for full weight bearing was significantly shorter in group C than groups A and B, and in group A than group B (P<0.05). Postoperative complications occurred in 11 patients of group A (21.6%), 14 patients of group B (26.4%), and 2 patients of group C (4.3%), showing significant difference between group C and group A or group B (P<0.05), but no significant difference was found between groups A and B (P>0.05). Hip Harris score at 12 months after operation had no significant difference between groups (P>0.05).ConclusionPFNA, LCP, and artificial femoral head replacement are all effective methods to treat femoral intertrochanteric fracture in aged patients. PFNA has the advantages of small incision, short operation time, less bleeding and simple procedure, and artificial femoral head replacement has the advantages of early time for full weight bearing, less bed rest time, and less complications. For these patients, PFNA and artificial femoral head replacement are appropriate.
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 evaluate the feasibility and effectiveness of proximal femoral nail anti-rotation (PFNA) combined with curettage and bone graft through Watson-Jones approach in the treatment of proximal femur benign tumors and tumor like lesions.MethodsThe clinical data of 38 patients with benign tumors and tumor like lesions in the proximal femur who were treated through the Watson-Jones approach with PFNA combined with curettage and bone graft between January 2008 and January 2015 were retrospective analysed. There were 24 males and 14 females with an average age of 28 years (range, 15-57 years). Pathological types included 20 cases of fibrous dysplasia, 7 cases of bone cyst, 5 cases of aneurysmal bone cyst, 3 cases of giant cell tumor of bone, 2 cases of enchondroma, and 1 case of non-ossifying fibroma. Before operation, hip pain occurred in 19 patients, pathological fracture occurred in 12 patients, limb shortening and coxa varus deformity was found in 4 patients, and 3 patients received surgery for the local recurrence. The operation time, intraoperative blood loss, and full-weight bearing time after operation were recorded. Patients were followed up to observe union of bone graft and the position of internal fixator on X-ray films and CT images. Visual analogue scale (VAS) score was used to evaluate the level of pain. The Musculoskeletal Tumor Society (MSTS93) score was used to evaluate lower limb function. Harris hip score was used to evaluate hip joint function.ResultsThe operation time was 130-280 minutes (mean, 182 minutes) and the intraoperative blood loss was 300-1 500 mL (mean, 764 mL). After operation, 3 cases of fat liquefaction of incision healed successfully by carefully dressing, and the rest incisions healed by first intention. All patients started partially weight-bearing exercise at 2-4 weeks after operation. The total weight-bearing time was 3-6 months (mean, 4.2 months). All the patients were followed up 24-108 months (median, 60 months). Imaging examination showed that the bone graft fused and the fusion time was 8-18 months (mean, 11.4 months). During the follow-up period, there was no complication such as pathological fracture, femoral head ischemic necrosis, hip joint dislocation, internal fixation loosening and fracture, and no tumor recurrence or distant metastasis occurred. At last follow-up, the VAS score, MSTS93 score, and Harris score were significantly improved when compared with preoperative ones (P<0.05).ConclusionThe treatment of proximal femoral benign lesions by PFNA combined with curettage and bone graft through the Watson-Jones approach is safe and effective, with advantages of better mechanical stability, less residual tumor, and less postoperative complications.
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 explore the effectiveness of proximal femoral nail antirotation (PFNA) combined with mini plate for reconstruction of lateral femoral wall in the treatment of type AO/Orthopaedic Trauma Association (AO/OTA) type 31-A3 intertrochanteric fracture. Methods The clinical data of 70 elderly patients with AO/OTA type 31-A3 intertrochanteric fracture treated between January 2013 and January 2018 were retrospectively analyzed. They were divided into group A (PFNA alone, 35 cases) and group B (PFNA combined with mini plate reconstruction of lateral femoral wall, 35 cases). There was no significant difference in the general data of gender, age, side, cause of injury, time from injury to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, fracture healing time, postoperative complications, and the tip apex distance (TAD) at 2 months after operation were recorded and compared between the two groups. Harris hip score was used to evaluate the function at 12 months after operation. Results Both groups were followed up 9-21 months, with an average of 16.6 months. The operation time and intraoperative blood loss in group A were significantly less than those in group B (P<0.05); there was no significant difference in TAD between the two groups at 2 months after operation (t=0.096, P=0.462). There were 5 complications (14.3%) occurred in group A, including 2 cases of blade perforating from the hip joint, 2 cases of screw back out, and 1 case of bone nonunion; only 1 case (2.9%) in group B had screw back out after operation; there was no significant difference in the incidence of complications between the two groups (χ2=2.917, P=0.088). All the fracture healed in group B, and 1 patient in group A suffered bone nonunion and eventually main nail fracture. The healing time of fracture in group A [(15.6±2.7) weeks] was significantly longer than that in group B [(12.5±2.5) weeks], showing significant difference (t=2.064, P=0.023). At 12 months after operation, according to Harris score, the results were excellent in 5 cases, good in 9 cases, fair in 13 cases, and poor in 8 cases in group A, the qualified rate (Harris score>70) was 77.14%; and the results were excellent in 7 cases, good in 11 cases, fair in 16 cases, and poor in 1 case in group B, the qualified rate was 97.14%; there was significant difference in the qualified rate between the two groups (χ2=6.248, P=0.012). Conclusion Compared with PFNA alone, the treatment of AO/OTA type 31-A3 intertrochanteric fracture with PFNA combined with mini plate reconstruction of lateral femoral wall can significantly reduce postoperative complications, promote fracture healing, and improve functional recovery of patients after operation.
ObjectiveTo investigate the association between the tip apex distance (TAD) and migration of helical blade in the femoral head of geriatric intertrochanteric fractures.MethodsA retrospective study of intertrochanteric fractures treated with the proximal femoral nail antirotation (PFNA) between June 2015 and June 2018 was performed. There were 32 males and 55 females with an average age of 84.7 years (range, 80-101 years). All of them were unilateral fresh closed intertrochanteric fractures caused by low energy injury. According to AO/Orthopaedic Trauma Association (AO/OTA) classification, 33 cases belonged to type 31-A1, 35 cases to type 31-A2, and 19 cases to type 31-A3. The time interval from injury to operation was 1-16 days (mean, 3.7 days). The TAD was measured according to immediate postoperative X-ray films. The cases were divided into two groups: group A with TAD less than 20 mm and group B with TAD greater than 20 mm. The difference of fracture healing and migration of helical blade between the two groups were observed.ResultsAccording to the TAD value immediately after operation, 49 patients in group A had TAD of 8.9-19.7 mm, with an average of 18.6 mm; 38 patients in group B had TAD of 20.1-41.4 mm, with an average of 27.7 mm. The 87 patients were followed up for an average of 11.7 months, ranging from 4 to 28 months. Three cases (all in group B) underwent screw blade cutting and displacement, which resulted in internal fixation failure, including 1 case with femoral head cut upward and 2 cases with femoral head penetrated inward. The remaining 84 cases had bone healing without internal fixation related complications such as fracture of internal fixator and fracture of femoral shaft. There was significant difference in the incidence of internal fixation failure between group A and group B (P=0.049). ConclusionReducing the TAD value of helical blade appropriately (15-20 mm) in PFNA internal fixation for intertrochanteric fracture patients over 80 years old can increase initial stability without increasing the risk of helical blade migration.
