Objective To explore the effectiveness of irreducible intertrochanteric femoral fracture in the elderly by treating with folding top technique and right-angle pliers prying and pulling under G-arm X-ray fluoroscopy. Methods The clinical data of 74 elderly patients with irreducible intertrochanteric femoral fracture admitted between February 2016 and December 2022 and met the selection criteria were retrospectively analyzed. Among them, 38 cases were treated with folding top technique combined with right-angle pliers prying and pulling under G-arm X-ray fluoroscopy and intramedullary nailing fixation (study group), and 36 cases were treated with limited open reduction combined with other reduction methods and intramedullary nailing fixation (control group). There was no significant difference in baseline data between the two groups, such as age, gender, cause of injury, affected side and classification of fractures, complicated medical diseases, and time from injury to operation (P>0.05). The operation time, intraoperative blood loss, hospital stay, fracture reduction time, fracture healing time, and complications of the two groups were recorded and compared. The quality of fracture reduction was evaluated by Baumgaertner et al. and Chang et al. fracture reduction standards. ResultsPatients in both groups were followed up 10-14 months, with an average of 12 months. The operation time and intraoperative blood loss in the study group were significantly less than those in the control group (P<0.05), there was no significant difference in hospital stay between the two groups (P>0.05). At 2 days after operation, according to the fracture reduction standards of Baumgaertner et al. and CHANG Shimin et al., the quality of fracture reduction in the study group was better than that in the control group, and the fracture reduction time in the study group was shorter than that in the control group, with significant differences (P<0.05). After operation, the fractures of the two groups all healed, and there was no significant difference in healing time between the two groups (P>0.05). During the follow-up, there was no complication such as incision infection, internal fixation failure, deep venous thrombosis of lower limbs, intramedullary nail breakage, spiral blade cutting, or hip varus in the two groups, except for 2 cases of coxa vara in the control group. Conclusion For the irreducible intertrochanteric femoral fracture, using folding top technique combined with right-angle pliers prying and pulling under G-arm X-ray fluoroscopy can obviously shorten the operation time, reduce the intraoperative blood loss, and improve the quality of fracture reduction.
Objective To evaluate effectiveness of proximal femur bionic nail (PFBN) in treatment of intertrochanteric fractures in the elderly compared to the proximal femoral nail antirotation (PFNA). Methods A retrospective analysis was made on 48 geriatric patients with intertrochanteric fractures, who met the selection criteria and were admitted between January 2020 and December 2022. Among them, 24 cases were treated with PFBN fixation after fracture reduction (PFBN group), and 24 cases were treated with PFNA fixation (PFNA group). There was no significant difference in baseline data such as age, gender, cause of injury, side and type of fracture, time from injury to operation, and preoperative mobility score, American Society of Anesthesiologists (ASA) score, Alzheimer’s disease degree scoring, self-care ability score, osteoporosis degree (T value), and combined medical diseases between the two groups (P>0.05). The operation time, intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, occurrence of complications, weight-bearing time after operation, and postoperative visual analogue scale (VAS) score, walking ability score, mobility score, self-care ability score were recorded and compared between the two groups. And the radiographic assessment of fracture reduction quality and postoperative stability, and fracture healing time were recorded. ResultsThe operations in both groups were successfully completed. All patients were followed up 6-15 months with an average time of 9.8 months in PFBN group and 9.6 months in PFNA group. The operation time was significantly longer in PFBN group than in PFNA group (P<0.05), but there was no significant difference in intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, change in activity ability score, and change in self-care ability score between the two groups (P>0.05). The weight-bearing time after operation was significantly shorter in PFBN group than in PFNA group (P<0.05), and the postoperative VAS score and walking ability score were significantly better in PFBN group than in PFNA group (P<0.05). Radiographic assessment showed no significant difference in fracture reduction scores and postoperative stability scores between the two groups (P>0.05). All fractures healed and there was no significant difference in fracture healing time between the two groups (P>0.05). The incidence of complications was significantly lower in PFBN group (16.7%, 4/24) than in PFNA group (45.8%, 11/24) (P<0.05). ConclusionCompared with PFNA, PFBN in the treatment of elderly intertrochanteric fractures can effectively relieve postoperative pain, shorten bed time, reduce the risk of complications, and facilitate the recovery of patients’ hip joint function and walking ability.
Objective To analyze the failure factors of proximal femoral nail antirotation (PFNA) in the treatment of geriatric intertrochanteric fractures. Methods The clinical data of 136 cases of intertrochanteric fracture treated with PFNA internal fixation between May 2015 and June 2017 were retrospectively analyzed. There were 106 males and 30 females, aged from 60 to 80 years, with an average age of 75.5 years. According to Evans-Jensen classification, there were 45 cases of type Ⅰ, 50 cases of type Ⅱ, 23 cases of type Ⅲ, 13 cases of type Ⅳ, and 5 cases of type Ⅴ. The time from injury to operation was 2-4 days, with an average of 3 days. According to the X-ray films before and after operation, the fracture types (stable and unstable), reduction quality (according to Baumgaertner’s criteria), integrity of lateral wall and posteromedial cortex of the patients with failure of PFNA internal fixation were summarized, and the causes of failure were analyzed. Results All the 136 patients were followed up 7-18 months (mean, 13.6 months). There were 17 cases (12.5%) of PFNA internal fixation failure after operation, including 3 cases of stable fracture and 14 cases of unstable fracture; the quality of fracture reduction was excellent in 2 cases, good in 5 cases, and poor in 10 cases; 10 cases with complete lateral wall and 7 cases with defect; 9 cases with complete posteromedial cortex and 8 cases with defect. Reasons for failure of internal fixation: ① There were 8 cases of coxa varus at 12 weeks after operation due to the loss of posteromedial cortex of femoral intertrochanteric, 7 of them continued non-weight-bearing observation and fracture healed at 6 months after operation; 1 case underwent total hip arthroplasty with spiral blade excision after operation. ② There were 7 cases of internal fixation failure caused by lateral wall defect, including 2 cases of screw blade retraction, continued non-weight-bearing observation, and removed the internal fixator after fracture healing; 2 cases of malunion of rotation with the rotation of no more than 15°, fracture healed at 6 months after operation without special treatment; and 3 cases of rupture of lateral intertrochanteric wall during operation, continued non-weight-bearing observation and fracture healed at 6 months after operation. ③ The distal locking of the main screw was deviated in 2 cases during operation. One of them was found and replanted in time during operation, and 1 case was found with fracture of femoral shaft on 3 days after operation, following 1 year of non-weight-bearing observation and fracture ending healing. Conclusion The types of intertrochanteric fractures (especially unstable fractures), the integrity of the proximal lateral wall of femur, and the defect of the posteromedial cortex are the internal risk factors for the success or failure of PFNA in the treatment of geriatric intertrochanteric fractures. The effective protection of the lateral wall during operation and the good quality of fracture reduction are the external factors that must be paid attention to.
ObjectiveTo investigate the effect of the screw blade position on the effectiveness of proximal femoral nail anti-rotation (PFNA) internal fixation for unstable intertrochanteric fractures in the elderly.MethodsA clinical data of 131 elderly patients with unstable intertrochanteric fractures who were treated with PFNA internal fixation between January 2010 and January 2017 was retrospectively analyzed. According to the anteroposterior X-ray films, the screw blades were placed in the middle of the femoral neck in 72 patients (group A) and at one-third of the femoral neck in 59 patients (group B). There was no significant difference between the two groups (P>0.05) in the gender, age, bone density, classification of fractures, other medical diseases, and the time between injury and operation. Multiple treatment indexes were analyzed, including complications, hip Harris score, the healing status of fracture, tip-apex distance (TAD), and the height of the tail nail.ResultsAll patients were followed up 11-14 months, with an average of 12.1 months. All incisions healed by first intention with no complications. All fractures healed and no significant difference in bone healing time between the two groups (Z=−0.190, P=0.849). At 6 months after operation, TAD was (2.23±0.07) cm in group A and (2.85±0.12) cm in group B, showing significant difference (t=−47.643, P=0.000); and the height of the tail nail was (1.72±0.14) cm in group A and (0.53±0.26) cm in group B, showing significant difference (t=31.031, P=0.000). According to the Harris score, the hip functions were rated as excellent in 48 cases, good in 15 cases, and poor in 9 cases in group A, while as excellent in 38 cases, good in 16 cases, and poor in 5 cases in group B, with no significant difference between the two groups (Z=−0.075, P=0.941).ConclusionFor the unstable intertrochanteric fracture in the elderly, the PFNA internal fixation with appropriated TAD and the screw blades placed in the middle or at one-third of the femoral neck can obtain good effectiveness.
ObjectiveTo compare the effectiveness of proximal femoral nail anti-rotation (PFNA) combined with minimally invasive percutaneous plate osteosynthesis (MIPPO) and Intertan intramedullary nail fixation by closed reduction in the treatment of AO/Orthopaedic Trauma Association (AO/OTA) type 31-A3.3 intertrochanteric fracture with incomplete lateral wall.MethodsThe clinical data of 54 patients with AO/OTA type 31-A3.3 intertrochanteric fracture who met the selection criteria and were admitted between January 2012 and January 2018 were retrospectively analyzed. According to different surgical methods, the patients were divided into group A (24 cases with lateral wall reconstruction by MIPPO combined with PFNA internal fixation) and group B (30 cases with Intertan intramedullary nail fixation by closed reduction only). There was no significant difference between the two groups (P>0.05) in terms of gender, age, side of injury, cause of injury, and combined medical diseases. The operation time, intraoperative blood loss, time to weight-bearing, fracture healing time, and postoperative complications were recorded and compared between the two groups. The tip apex distance (TAD) was measured at 2 days, 2 months, and 1 year after operation. At 12 months after operation, the hip joint function was evaluated according to Harris scoring standard, and the rate of conformity (Harris score were more than 70) was calculated.ResultsThe wounds of the two groups healed by first intention, without infection, skin deformity, and other incision complications. The operation time and intraoperative blood loss of group A were significantly more than those of group B, and the time to weight-bearing and fracture healing were significantly shorter than those of group B (P<0.05). The patients were followed up 9-20 months (mean, 14.7 months) in group A and 9-19 months (mean, 13.8 months) in group B. There was no significant difference in TAD values at 2 days, 2 months, and 1 year after operation between the two groups (P<0.05), and there was also no significant difference in TAD values between the postoperative time points (P>0.05). There was 1 case of infection, 1 case of screw withdrawal, 2 cases of screw removal, and 1 case of bone nonunion in group B, the incidence of complications was 16.7%; there was only 1 case of screw withdrawal combined with screw blade withdrawal in group A, the incidence of complications was 4.2%; there was no significant difference between the two groups (χ2=2.109, P=0.146). At 12 months after operation, the Harris scores of pain, function, malunion, range of motion, and total score in group A were significantly better than those in group B (P<0.05). The rate of conformity of group A was 95.83% (23/24) and 76.67% (23/30) in group B, and the difference between the two groups was significant (χ2=3.881, P=0.049).ConclusionFor the AO/OTA type 31-A3.3 intertrochanteric fracture with incomplete lateral wall, compared with the closed reduction Intertan intramedullary nail fixation, the incidence of internal fixation failure after MIPPO reconstruction with lateral wall combined with PFNA fixation was lower, the time to weight-bearing was earlier, and the postoperative function was better.
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 compare the effectiveness of proximal femoral nail anti-rotation (PFNA) in the treatment of intertrochanteric fracture of femur in traction bed supine position and non-traction bed lateral position.MethodsA retrospective analysis of 102 elderly patients with intertrochanteric fracture of femur who met the selection criteria between January 2013 and April 2018 was made. According to the different operative positions, the patients were divided into two groups: group A (50 cases, PFNA internal fixation in traction bed supine position) and group B (52 cases, PFNA internal fixation in non-traction bed lateral position). There was no significant difference in age, gender, fracture side, cause of injury, AO classification, complications, and time from injury to operation between the two groups (P>0.05). The preoperative preparation time, incision length, operation time, intraoperative blood loss, intraoperative X-ray fluoroscopy times, fracture healing time, and complications were recorded and compared between the two groups, and the effectiveness was evaluated by Harris hip score at 1 year after operation.ResultsThere was no significant difference in incision length between groups A and B (t=1.116, P=0.268). In addition, the preoperative preparation time, operation time, intraoperative blood loss, and intraoperative X-ray fluoroscopy times in group A were significantly greater than those in group B (P<0.05). Both groups were followed up 12-14 months, with an average of 13 months. There were 3 postoperative complications in group A and group B respectively. In group A, there were 2 cases of hip joint pain and 1 case of local fat liquefaction (healed after dressing change); in group B, there were 2 cases of hip joint pain and 1 case of deep vein thrombosis in lower extremity; there was no significant difference in the incidence of postoperative complications between the two groups (P=0.642). The patients of the two groups had a good result of fracture reduction and the internal fixation quality, and there was no main nail loosening, screw fracture, spiral blade cutting, withdrawal, and the nail breakage occurred, and no nonunion of bone, coxa vara, and other complications occurred. X-ray showed that the fracture healed in both groups, and there was no significant difference in fracture healing time between the two groups (t=1.515, P=0.133). There was no significant difference in Harris hip score between the two groups at 1 year after operation (t=0.778, P=0.438).ConclusionCompared with the traction bed supine position, PFNA internal fixation for intertrochanteric fracture of femur in the non-traction bed lateral position has the advantages of short preparation time, short operation time, less intraoperative blood loss, less X-ray fluoroscopy times, and satisfactory postoperative recovery effect.
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.
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 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.
