Objective To analyse the factors of complications aftertreatment of intertrochanteric fractures with Gamma nail. Methods From January 1998 to May 2004, 50 patients were treated with Gamma nail, including 18 males and 32 females and ageing from 47 to 82 years. The locations were the left side in 16 cases andthe right in 34 cases. According to Evans classification, there were 4 cases oftype Ⅰ, 2 cases of type Ⅱ, 23 cases of type Ⅲ, 10 cases of type Ⅳ and 11 cases of type Ⅴ. Results Fifty patients were followed up 429 months. Accordingto the Harris criterion for evaluation, the results were excellent and good in 35 cases, showing sthenic weight loading walking and normal range of motion of the hip joint. The postoperative complications appeared in 15 cases: 5 cases of coxa vara or coxa valga, 3 cases of rotation deformity of lower limb, 2 cases oftension screwprotrusions and lower shorten, 1 case of failure of internal fixation, 1 case of femoral fracture, 2 cases of coxalgia and 1 case of pain in knee joint and stiff knee joint. Conclusion The reason of complications was various, mainly lies in insufficient comprehension and analysis of the types of fractures, unfamiliarity with the characteristics and usage of the instruments and neglected rehabi litation instruction, inappropriate functional training and too early weight loading after operation.
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.
ObjectiveTo analyze the reasons and the influence of internal fixation about the guide pin eccentricity of helical blade during proximal femoral nail anti-rotation (PFNA) internal fixation for femoral intertrochanteric fractures.MethodsA retrospective analysis of the intraoperative imaging data of 175 patients with femoral intertrochanteric fractures, who underwent closed reduction and PFNA internal fixation between January 2018 and January 2020, was performed. There were 76 males and 99 females with an average age of 79.8 years (mean, 61-103 years). The internal between admission and operation was 12-141 hours (median, 32 hours). According to AO/Orthopaedic Trauma Association (AO/OTA) classification, the fractures were rated as type 31-A1 in 64 cases and type 31-A2 in 111 cases. In the intraoperative fluoroscopy image by C-arm X-ray machine, the caputcollum-diaphysis (CCD) was measured after closed reduction and internal fixation, respectively; the angles between the center line of the head nail hole and the axis of proximal nail and between the axis of guide pin and proximal nail were measured, and the difference between the two angles was evaluated; the quality of fracture reduction was evaluated according to the alignment of the medial cortex, anterior cortex of the head and neck bone block, and femoral shaft cortex; the position of the helical blade in the femoral head was evaluated according to the Cleveland method.ResultsThe CCDs of proximal femur were (134.6±6.8)° after closed reduction and (134.9±4.3)° after internal fixation. There was no significant difference between pre- and post-internal fixation (t=0.432, P=0.766). The angles between the center line of the head nail hole and the axis of proximal nail and between the axis of guide pin and proximal nail were (125.4±2.44)° and (126.3±2.3)°, respectively, showing significant difference (t=2.809, P=0.044). The difference between the two angles was (0.8±2.2)°. The guide pin eccentricity of helical blade occurred in 47 cases. After tapping the helical blade along the eccentric guide pin, 10 cases had fracture reduction loss, and 5 cases had a poor position of the helical blade in the femoral head. ConclusionDuring PFNA internal fixation, a variety of reasons can lead to the eccentric position of the guide pin of helical blade, including unstable fracture, soft tissue inserted, severe osteoporosis, mismatched tool, and fluoroscopic imaging factors. It is possible that the fracture end would be displaced again and the helical blade position may be poor when knocking into the helical blade along the eccentric guide pin. During operation, it should be judged whether the direction of the guide pin needs to be adjusted according to the eccentric angle.
Objective To evaluate the clinical effect of bipolar long-stem prosthetic replacement on the treatment of comminuted intertrochanteric fracture of hip in the elderly osteoporotic patients. Methods From March 2000 to August 2003, 18 patients who were more than 72 years old with comminuted intertrochanteric fracture were treated with bipolar longstem prosthetic replacement. There were 8 males and 10 females (aged from 72 to 91). Fractured fragments of large trochanter and minor trochanter should be preserved during the operation so that the fragments can be fixed with steel wires and insertion of artificial femoral head.The surgical approach and operative technique, the average course of treatment in hospital, the average time to ambulate with full-weight bearing on the operated limb after the operation, complication, and mortality were observed. Results All patients were followed up 6 to 28 months(16.2 months on average). The average course of stay at hospital was 16 days. The average time to ambulate was 32 days. The incidence of the pain of the hip joint was one-eighteenth, and one patient due to another disease was unable to walk without using twocrutches one month after the surgery. The mortality of the patients was oneeighteenth one year after the surgery. Conclusion Bipolar longstem prosthetic replacement for the treament of comminuted intertrochanteric fractures in the elderly osteoporotic patients proves to be a suitable alternative.Patients have better prognosis, early full-weight bearing, rapid rehabilitation, and fewer complications.
Objective To evaluate the biomechanical properties of proximal femoral medial buttress plate (PFMBP) for fixing the reverse oblique intertrochanteric fractures by comparing with proximal femoral locking compression plate (PFLCP) and proximal femoral nail antirotation (PFNA). Methods Eighteen synthetic femoral bone models (Synbone) were divided into 3 groups (group PFLCP, group PFNA, and group PFMBP), 6 models in each group; an AO 31-A3.1 reverse oblique femoral intertrochanteric fracture was made based on the same criterion. After being fixed and embeded, the axial load testing, torsion testing, and axial load-to-failure testing were performed on each model. The axial displacement of different loads, torque of different torsion angles, and failure load of each model were recorded, and the stiffness of axial load and torsion were calculated. Results The axial stiffness in groups PFLCP, PFNA, and PFMBP were (109.42±30.14), (119.13±29.14), and (162.05±22.05) N/mm respectively, showing significant differences between groups (P<0.05). There were significant differences in torque between different torsion angles in the same group, as well as in the torque between groups at the same torsional angle (P<0.05). The torsion stiffness in groups PFLCP, PFNA, and PFMBP were (1.45±0.44), (1.10±0.13), and (1.36±0.32) N·mm/deg respectively; there were significant differences when compared groups PFLCP and PFMBP with group PFNA (P<0.05), but no significant difference was found between group PFLCP and group PFMBP (P>0.05). The failure loads of groups PFLCP, PFNA, and PFMBP were (1 408.88± 0.17), (1 696.56±0.52), and (2 154.65±0.10) N respectively, showing significant differences between groups (P<0.05). Conclusion The newly-designed PFMBP is better than PFNA and PFLCP in axial load stiffness and torsion stiffness for fixing reverse oblique intertrochanteric fracture by biomechanical test, indicating that reconstruction of medial stability is a key element for unstable intertrochanteric fracture.
Objective To investigate the perioperative changes in serum interleukin 6 (IL-6) levels in elderly male patients with intertrochanteric fractures, and provide evidence for inflammatory control in this patient population. Methods The clinical data of 40 male patients aged more than 60 years with intertrochanteric fractures who met the selection criteria between January 2021 and December 2022 were retrospectively analyzed, including 25 non-osteoporosis patients (T value>?2.5, group A) and 15 osteoporosis patients (T value≤?2.5, group B). In addition, 40 healthy men aged more than 60 years old were included as controls (group C) according to the age matching rule. There was no significant difference in age, smoking history, drinking history, body mass index, complications (hypertension and diabetes), alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, and total protein among the 3 groups (P>0.05). Serum samples were collected from group C subjects and from groups A and B patients preoperatively and on postoperative days 1, 3, 5, and 7. IL-6 levels were measured using ELISA assay. Pearson correlation analysis was used to assess the relationship between IL-6 levels and T values at various time points in groups A and B. Postoperative complications during hospitalization and 1-year mortality rates were recorded for groups A and B. Results Preoperative IL-6 levels were significantly higher in groups A and B than in group C (P<0.05), with group B being significantly higher than group A (P<0.05). In groups A and B, IL-6 levels increased significantly on postoperative day 1 compared to preoperative levels and then gradually decreased, approaching preoperative levels by postoperative day 7. IL-6 levels in group B were significantly higher than those in group A at all postoperative time points (P<0.05). Correlation analysis showed that IL-6 levels were negatively correlated with T values at all perioperative time points in all patients from groups A and B (P<0.05). Complications occurred in 4 patients (16.0%) in group A, including 2 cases of pulmonary infection, 1 case of urinary tract infection, and 1 case of heart failure, and in 3 patients (20.0%) in group B, including 2 cases of pulmonary infection and 1 case of gastrointestinal bleeding. There was no significant difference in the incidence of complications between the two groups (χ2=0.104, P=0.747). There were 2 cases (8.0%) and 4 cases (26.7%) died within 1 year after operation in groups A and B, respectively, and there was no significant difference in 1-year mortality rates between the two groups (χ2=2.562, P=0.109). Conclusion Serum IL-6 levels significantly increase in the early postoperative period in elderly male patients with intertrochanteric fractures, especially in those with osteoporosis. Monitoring the inflammatory state and promptly controlling the inflammatory response during the perioperative period, may reduce complications and improve postoperative survival in this patient population.
Objective To compare the effectiveness of lower extremity axial distractor (LEAD) and traction table assisted closed reduction and intramedullary nail fixation in treatment of femoral subtrochanteric fracture. Methods The clinical data of 117 patients with subtrochanteric fracture of femur treated by closed reduction and intramedullary nail fixation between May 2012 and May 2022 who met the selection criteria were retrospectively analyzed. According to the auxiliary reduction tools used during operation, the patients were divided into LEAD group (62 cases with LEAD reduction) and traction table group (55 cases with traction table reduction). There was no significant difference in baseline data, such as gender, age, injured side, cause of injury, fracture Seinsheimer classification, time from injury to operation, and preoperative visual analogue scale (VAS) score, between the two groups (P>0.05). Total incision length, operation time, intraoperative blood loss, fluoroscopy frequency, closed reduction rate, fracture reduction quality, fracture healing time, weight-bearing activity time, and incidence of complications, as well as hip flexion and extension range of motion (ROM), Harris score, and VAS score at 1 month and 6 months after operation and last follow-up were recorded and compared between the two groups. Results There were 14 cases in the LEAD group from closed reduction to limited open reduction, and 43 cases in the traction table group. The incisions in the LEAD group healed by first intention, and no complication such as nerve and vascular injury occurred during operation. In the traction table group, 3 cases had perineal crush injury, which recovered spontaneously in 1 week. The total incision length, operation time, intraoperative blood loss, fluoroscopy frequency, and closed reduction rate in the LEAD group were significantly better than those in the traction table group (P<0.05). There was no significant difference in the quality of fracture reduction between the two groups (P>0.05). Patients in both groups were followed up 12-44 months, with an average of 15.8 months. In the LEAD group, 1 patient had delayed fracture union at 6 months after operation, 1 patient had nonunion at 3 years after operation, and 1 patient had incision sinus pus flow at 10 months after operation. In the traction table group, there was 1 patient with fracture nonunion at 15 months after operation. X-ray films of the other patients in the two groups showed that the internal fixator was fixed firmly without loosening and the fractures healed. There was no significant difference in fracture healing time, weight bearing activity time, incidence of complications, and postoperative hip flexion and extension ROM, Harris score, and VAS score at different time points between the two groups (P>0.05). ConclusionFor femoral subtrochanteric fracture treated by close reduction and intramedullary nail fixation, compared with traction table, LEAD assisted fracture reduction can significantly shorten the operation time, reduce intraoperative blood loss and fluoroscopy frequency, reduce incision length, effectively improve the success rate of closed reduction, and avoid complications related to traction table reduction. It provides a new method for good reduction of femoral subtrochanteric fracture.
Objective To compare the inter-observer agreement, consistency with the gold standard, and accuracy of the 2007 and 2018 versions of the AO/OTA classification in femoral intertrochanteric fractures, and to identify easily confused fracture types. Methods X-ray images of patients with femoral intertrochanteric fractures at Daping Hospital, Army Medical University between 2017 and 2021 were retrospectively collected. Three senior orthopedic trauma surgeons independently classified the fractures using both the 2007 and 2018 AO/OTA versions. A committee of five experts established the gold standard. Kappa coefficients were used to evaluate inter-observer agreement and consistency with the gold standard, while a confusion matrix was used to analyze accuracy and confusion points. Results A total of 236 patients were included. Regarding inter-observer agreement, the 2007 version was superior to the 2018 version at the subtype level [Kappa value: (0.473-0.739) vs. (0.322-0.658)], with no significant difference at the subgroup level [Kappa value: (0.234-0.453) vs. (0.204-0.442)]. Regarding consistency with the gold standard, the 2018 version was slightly better than the 2007 version [Kappa value: (0.332-0.629) vs. (0.269-0.581)] at the subgroup level. In terms of accuracy, the 2007 version showed higher accuracy at the subtype level (72.50% vs. 70.11%), whereas the 2018 version demonstrated better accuracy at the subgroup level (59.04% vs. 51.99%). The most easily confused subtypes in both versions were A1 and A2. At the subgroup level, A2.2 was the most easily confused type in both versions. Conclusions There is inconsistency in the application of both classification versions by surgeons. The 2007 version demonstrates slightly better inter-observer agreement at the subtype level, while the 2018 version shows better accuracy at the subgroup level. The A2.2 subgroup is a major point of confusion, suggesting that clinical attention should be focused on this type or that auxiliary tools may be needed to improve accuracy.
ObjectiveTo explore the efficacy and safety of intravenous injection of tranexamic acid (TXA) combined with local use of TXA cocktail in intertrochanteric fracture fixation with proximal femoral nail antirotation (PFNA).MethodsPatients with intertrochanteric fractures who underwent close reduction and internal fixation with PFNA between February 2018 and March 2019 were enrolled in the study. Among them, 45 patients who met the selection criteria were included in the study and randomly allocated into 3 groups (n=15). The patients in group A were not received TXA during perioperative period. The patients were intravenously injected of 1.0 g TXA before operation in group B and combined with local use of TXA cocktail during operation in group C. There was no significant difference in the age, gender, body mass index, fracture classification, disease duration, and complications between groups (P>0.05). The perioperative blood loss and blood transfusion rate, the visual analogue scale (VAS) score before operation and at 12, 24, and 48 hours after operation, the levels of prostaglandin E2 (PGE2) and bradykinin (BK) before operation and at 1 and 3 days after operation, postoperative complications, and the maximum amplitude (MA) of thromboelastogram were recorded and compared between groups.ResultsThe total blood loss, hidden blood loss, and visible blood loss were significantly lower in groups B and C than those in group A (P<0.05), and the total blood loss and hidden blood loss were significantly lower in group C than those in group B (P<0.05). There was no significant difference in the blood transfusion rate, preoperative VAS scores and the levels of PGE2 and BK between groups (P>0.05). The postoperative VAS scores and the levels of PGE2 and BK were significantly lower in group C than in groups A and B (P<0.05). There was no significant difference in pre- and post-operative MA of thromboelastogram between groups (P>0.05). The incidences of postoperative complications were 33.33% (5/15), 20.00% (3/15), and 13.33% (2/15) in groups A, B, and C, respectively, with no significant difference between groups (χ2=1.721, P=0.550).ConclusionFor intertrochanteric fractures, application of intravenous injection of TXA combined with local use of TXA cocktail in PFNA fixation can reduce perioperative blood loss, relieve pain after operation, and do not increase the risk of complications.
