Objective To identify an evidence-based treatment for an elderly patient with intertrochanteric fractures. Methods Clinical problems were presented on the basis of the patient’s conditions, and evidence was collected from the NGC (2000 to 2009), The Cochrane Library (Issue 4, 2009), TRIP Database, PubMed (1966 to 2009) and CBM (1978 to 2009). Treating strategies were formulated in terms of the three-combination principle (best evidence, the doctor’s professional knowledge and the patient’s desire). Results Three guidelines and sixteen studies were included. The current evidence indicated that surgery was the preferred solution to intertrochanteric fractures of the elderly patient. The sliding hip screw (SHS) appeared superior to others. There was insufficient evidence to support the routine use of closed suction drainage in orthopedic surgeries. Early surgery was associated with shorter hospital stay and improved mortality. Antibiotic prophylaxis significantly reduced infections. In order to lower the risk of venous thromboembolism, pharmacological prophylaxis should be carried out when the patient was admitted to hospital and be assisted with mechanical prophylaxis after surgery. Nutritional supplementation was conducive to the recovery of the patient. Rehabilitation ought to be performed as soon as possible. Considering the patient’s condition, the treatment option was established according to the available evidence and guidelines. Short-term follow-up showed a good outcome. Conclusion Through the evidence-based method, an individual treatment plan could obviously improve the treatment effect and prognosis.
Objective To investigate the influence of the integration of fracture treatment and exercise rehabilitation on the effectiveness in the patients with intertrochanteric fracture of femur. Methods Between January 2007 and December 2009, 3 873 patients with intertrochanteric fracture of femur were surgically treated in 56 hospitals. Of them, 1 970 cases were treated with rehabilitation training according to scale of safety assessment of early exercise rehabilitation of patients with fractures (trial group), 1 903 cases were treated with traditional rehabilitation training methods (control group). There was no significant difference in age, gender, fracture type, internal fixation type, or postoperative safety score between 2 groups (P gt; 0.05). Results All the patients were followed up 13-49 months (mean, 30.5 months). There was no significant difference in the incidences of bone nonunion, delayed union, and systemic complication between 2 groups (P gt; 0.05); significant differences were found in the incidences of incision complication, deep vein thrombosis of the lower extremity, and the overall complication between 2 groups (P lt; 0.05). At 6 and 12 months after operation, the trial group was significantly better than the control group in the recovery of hip motion, curative effectiveness classification, and the excellent and good rate (P lt; 0.05). Conclusion The treatment of intertrochanteric fracture of the femur guided by the integration of fracture treatment and exercise rehabilitation can apparently improve the prognosis and reduce the incidence of complications.
ObjectiveTo summarize the patterns and research progress of the concomitant ipsilateral fractures of intracapsular femoral neck and extracapsular trochanter, and to provide a common language among orthopedic surgeons for scientific exchange.MethodsAccording to related literature and authors own experiences concerning the anatomic border between femoral neck and trochanter region, the intertrochanteric line (or intertrochanteric belt) and its capsularligament attachment footprint, fracture patterns, and treatment strategies were reviewed and analyzed.ResultsWith the rapid growing of geriatric hip fractures, an increased incidence was noted in recent years regarding the proximal femoral comminuted fractures that involving ipsilateral intracapsular neck and extracapsular trochanter regions simultaneously. But the concept of femoral neck combined with trochanter fractures was ambiguous. Based on the anatomic type of femoral neck fracture, the location of fracture center, and the ability to achieve direct inferior calcar or anteromedial cortex-to-cortex apposition and buttress, we classified these complex fractures into 3 sub-types: ① Segmental femoral neck fractures (two separate fracture centers at subcapital and trochanteric region respectively); ② Femoral neck fracture (trans-cervical) with extension to the supero-lateral trochanteric region (fracture center in femoral neck); ③ Trochanteric fracture with extension to the medio-inferior femoral neck region (fracture center in trochanter, comminuted basicervical fracture, or variant type of comminuted trochanter fracture). For treatment strategy, surgeons should consider the unique characteristics of femoral neck and trochanter, usually with combined fixation techniques, or arthroplasty supplemented with fixation.ConclusionCurrently there is no consensus on diagnosis and terminology regarding the concomitant ipsilateral fractures of femoral neck and trochanter. Further studies are needed.
Objective To study the technique and effect of adjunctive cancellous screw in treatment of intertrochanteric fractures with dynamic hi p screw (DHS) fixation. Methods Between April 2004 and August 2007, 33 patients with intertrochanteric fracture were treated with DHS fixation and adjunctive cancellous screw. There were 13 males and 20 females, aging 43-82 years with an average age of 67 years. Fractures were caused by traffic accident in 7 patients, by fall ing from height in 11 patients, by sprain in 15 patients. All fractures were closed. The patients were operated 3-12 days after injury. According to Evans classification, there were 12 cases of type II, 15 cases of type III, and 6 cases of type IV. Twenty-twocases had osteoporosis. Weight bear time and compl ication were recorded. Fracture heal ing and neck-shaft angle were observed on radiogram. Hip functions were evaluated using Radford criterion. Results Thirty-three patients had no intraoperative compl ications with incision heal ing by first intension. All patients were followed up from 14 months to 38 months, with an average of 21 months. Fracture heal ing was achieved within 14 weeks to 21 weeks, with an average of 17 weeks after operations. The neck-shaft angles were (134.2 ± 13.7)° 3 days after operation, (128.6 ± 8.9)° 8 weeks after operation, and (128.5 ± 9.3)° after fracture heal ing, showing no significant difference when compared with that of the third day after operation (P gt; 0.05). According to the Radford criterion at last follow-up, the excellent and good rate of hi p function was 93.9% (excellent in 21 cases, good in 10 cases, and poor in 2 cases). Compl ications such as loosening, breakage, or grievous migration of hardware were not observed. Conclusion The adjunctive cancellous screw in treatment of intertrochanteric fractures with DHS fixation can provide counteraction of tension and rotation, promote fixation stabil ity, enhance fracture heal ing and decrease compl ication.
Forty cases of intertrochanteric fractures of femur were treated with percutaneous nonmetallic external fixator. The patients were followed up for 6 months to 3 years, and the fractures were all united without coxa vara or shirtening deformities. There was no mortality in this series. This method had the advantages ofbeing simple, save time and effort, less traumatic and early ambulation. The design of the apparatus tallied with the biomechanics of the neck and shaft of the femur.
Objective To investigate the reasons of failure of Gamma nail treatment for intertrochanteric fractures and define operative techniques of the revision surgery. Methods From January 1999 to January 2008, 20 cases of 432 patients treated with Gamma nails for intertrochanteric fractures were revised. There were 9 males and 11 females, aged 24-87 years (median 65 years). Among them, there were 4 cases of femoral shaft fracture, 2 cases of screw penetrating the femoral head,11 cases of screw cutting out the femoral head and neck, 2 cases of internal rotation malformation, and 1 case of nfection. The operative procedures of revision were as follows: 4 cases were treated with the long Gamma nail, 4 cases by adjusting the position of Gamma nail, 11 cases with artificial femoral head replacement, and 1 case by removing Gamma nail and debriding and reimplant the Gamma nail. Results The hospital ization days were 16-28 days (21.2 days on average); the bleeding volume during operation was 150-600 mL (380 mL on average). All wounds healed by first intention. Bed rest days were 7-15 days (12.5 days on average). All the patients were followed up for 1-8 years (5 years on average). The operations were successful, the femoral intertrochanteric fracture and femoral shaft fracture reached bony union. Compl ications such as loosening, breakage of hardware and coxa adduct were not observed. No loosening and dislocation of the prosthesis occurred. Among the patients with compl ications, 9 patients were treated with a Gamma nail again. Fracture heal ing was achieved within 2 to 5 months, with an average of 3 months. According to the WANG Fang et al. criterion for hip joint function, the results were excellent in 7 cases and good in 2 cases. In 11 patients who receieved artificial femoral head replacement, the hip joint function restored to normal. Harris score was 90-93. Conclusion Various causes such as osteoporosis, ti p-apex distance ( 25 mm), femoral shaft malformation, Gamma nail shortcomings may lead to compl ications after Gamma nail treatment for intertrochanteric fractures. Good results will be achieved by different revision techniques.
ObjectiveTo formulate the classification criteria of femoral intertrochanteric fractures based on irreducibility or not in order to predict the difficulty of fracture recovery.MethodsA clinical data of 244 patients with closed femoral intertrochanteric fractures admitted between January 2017 and March 2020 was retrospectively analyzed. There were 116 males and 128 females with an average age of 77.9 years (range, 45-100 years). The cause of injury included falling in 190 cases, traffic accident in 36 cases, smashing in 13 cases, and falling from height in 5 cases. The time from injury to operation was 1-14 days (mean, 3.6 days). According toAO/Orthopaedic Trauma Association (AO/OTA) classification, the fractures were classified as type 31-A1 in 38 cases, type 31-A2 in 160 cases, and type 31-A3 in 46 cases. According to whether the recovery difficulty occurred after intraoperative closed traction reset, the patients were divided into reducible-group and irreducible-group; combined with the literature and preoperative imaging data of two groups, the classification criteria of femoral intertrochanteric fractures was formulated based on the irreducibility or not. The 244 fractures were classified by the doctors who did not attend the operation according to the classification criteria, predicted the difficulty of fracture reduction, and compared with the actual intraoperative reduction situation.ResultsThe 244 patients were divided into reducible-group (n=164, 67.21%) and irreducible-group (n=80, 32.79%) according to the intraoperative difficulty of reduction. Comparing the imaging data and characteristics of the two groups, and formulating the classification criteria of femoral intertrochanteric fractures based on irreducibility or not, the fractures were mainly divided into two categories of irreducibility and reducibility. The fractures of irreducibility category was divided into typesⅠ-Ⅴ, among which type Ⅲ was divided into subtypes 1-4; the fractures of reducibility category was divided into typesⅠand Ⅱ. Compared with the actual intraoperative evaluation results, the total accuracy rate of the doctors who did not attend the operation was 81.15% (198/244) based on the classification criteria of femoral intertrochanteric fractures. The accuracy rate of irreducibility category was 65.74% (71/108), and the reducibility category was 93.38% (127/136). All patients were followed up 13-25 months, with an average of 17.6 months. All fractures healed except 2 cases died of infection.ConclusionThe classification criteria of femoral intertrochanteric fractures based on irreducibility or not can accurately predict the reducible cases preoperatively, and most of the irreducible cases can be correctly predicted in a wider way. But the classification criteria still need to be further improved and supplemented.
ObjectiveTo investigate the efficacy and safety of intravenous combined with topical administration of tranexamic acid (TXA) in reducing blood loss after intramedullary fixation of intertrochanteric femoral fractures by a prospective controlled trial.MethodsPatients with intertrochanteric femoral fractures, who were admitted for intramedullary fixation between June 2015 and July 2019, were selected as the study subjects, 120 of whom met the selection criteria. The patients were randomly assigned to 3 groups: intravenous administration group (group A, 41 cases), topical administration group (group B, 40 cases), and combined administrations group (group C, 39 cases). In group A, 4 patients occurred deep vein thrombosis of lower extremity before operation, 1 patient died of myocardial infarction on the 5th day after operation, and 1 patient developed severe pulmonary infection after operation. In group B, 2 patients occurred deep vein thrombosis of lower extremity before operation and 1 patient had iatrogenic fracture during operation. In group C, 3 patients occurred deep vein thrombosis of lower extremity before operation and 1 patient developed pulmonary infection before operation and gave up surgical treatment. All the above patients were excluded from the study, and the remaining 107 cases were included in the analysis, including 35, 37, and 35 cases in groups A, B, and C, respectively. There was no significant difference in gender, age, height, body mass, injury cause, fracture side and type, the interval between injury and operation, and preoperative hemoglobin (Hb), hematocrit between groups (P>0.05). Intraoperative TXA (15 mg/kg) was injected intravenously in group A at 30 minutes before operation, and 1 g of TXA was injected into the medullary cavity in group B after the proximal femur was grooted and before the intramedullary nail implantation, respectively. TXA was given in group C before and during operation according to the administration methods and dosage of groups A and B. Total blood loss, maximum Hb decrease, blood transfusion rate, operation time, fracture healing time, and the incidence of complications were recorded and compared between groups. The hip joint function were evaluated by Harris score. ResultsThere was no significant difference in operation time between groups (P>0.05). The total blood loss, the maximum Hb decrease, and the blood transfusion rate in group B were the highest, followed by group A and group C, and the differences between groups were significant (P<0.05). No incision infection or pulmonary embolism occurred in the 3 groups after operation. The incidence of anemia in group C was significantly lower than that in groups A and B, the difference was significant (P<0.05). There was no significant difference in the incidence of subcutaneous hematoma, aseptic exudation, and deep vein thrombosis of lower extremity between groups (P>0.05). All patients in the 3 groups were followed up 8-35 months, with an average of 16.2 months. The fracture healing time of groups A, B, and C was (6.12±1.78), (5.89±1.63), and (5.94±1.69) months, respectively, and there was no significant difference between groups (P>0.05). At last follow-up, the Harris scores of the hip joints in groups A, B, and C were 83.18±7.76, 84.23±8.01, and 85.43±8.34, and the difference was not significant (P>0.05). ConclusionPreoperative intravenous injection combined with intraoperative topical application of TXA can effectively reduce blood loss and blood transfusion after intramedullary fixation of femoral intertrochanteric fracture, without increasing the risk of deep vein thrombosis, and the efficacy is better than that of intravenous injection or topical administration.
ObjectiveTo investigate the effectiveness and advantages of skeletal tractor in closed reduction and proximal femoral nail antirotation (PFNA) internal fixation of intertrochanteric fracture compared with traction table.MethodsThe clinical data of 86 patients with intertrochanteric fractures, who were treated with closed reduction and PFNA internal fixation between October 2016 and March 2018 and met the selection criteria, was retrospectively analysed. Among them, 44 cases were treated with skeletal tractor (trial group) and 42 cases were treated with traction table (control group). There was no significant difference between the two groups in gender, age, cause of injury, fracture side, AO classification, and degree of osteoporosis (P>0.05). The preoperative position time, operation time, intraoperative fluoroscopy times, intraoperative blood loss, fracture healing time, intraoperative and postoperative complications, and postoperative Harris score were compared between the two groups.ResultsThe operation was successfully completed in both groups. Compared with the control group, the patients in the trial group had shorter preoperative position time and operation time, fewer intraoperative fluoroscopy times, and less intraoperative blood loss (P<0.05). The patients were followed up 12-21 months in trial group (mean, 14.2 months) and 12-22 months in control group (mean, 14.3 months). Venous thrombosis of lower extremity occurred in 8 patients (3 cases of trial group and 5 cases of control group) after operation. Internal fixation failure occurred in 5 patients (2 cases of trial group and 3 cases of control group) during 1 year after operation. All fractures healed except for those with internal fixation failure, the fracture healing time was (11.6±2.9) weeks in trial group and (12.4±3.6) weeks in control group; and there was no significant difference between the two groups (t=1.250, P=0.214). At 1 year after operation, Harris score of the trial group was 86.2±5.9 and that of the control group was 84.1±6.1. There was no significant difference between the two groups (t=1.768, P=0.080).ConclusionCompared with traction table, skeletal tractor in closed reduction and PFNA internal fixation of intertrochanteric fracture can significantly shorten the preoperative position time and operation time, reduce the intraoperative fluoroscopy times, improve the operation efficiency, and have similar effectiveness.
ObjectiveTo analyze the risk factors for postoperative mortality of elder patients with intertrochanteric fractures.MethodsPatients with intertrochanteric fractures who underwent proximal femoral interlocking intramedullary nail fixation between January 2014 and December 2015 were enrolled in the study. Among them, 135 patients who met the selection criteria were included in the study, and the clinical data were collected, including gender, age, time from admission to surgery, comorbidities, and preoperative hemoglobin, albumin, and total lymphocyte count (TLC), and nutritional status. Univariate analysis and Cox proportional hazards regression model were used to screen the risk factors for postoperative mortality.ResultsTwenty-seven patients (20.0%) died within 2 years after surgery, and 16 (11.9%) died within 1 year after surgery. Univariate analysis showed that age, coronary atherosclerotic heart disease, number of comorbidities, preoperative hemoglobin and albumin levels were the influencing factors of postoperative mortality in elder patients with intertrochanteric fractures treated with proximal femoral interlocking intramedullary nail fixation (P<0.05). Multivariate analysis showed that age (≥80 years), combined more than 2 medical diseases, and preoperative albumin (<35 g/L) were the independent risk factors for postoperative mortality (P<0.05).ConclusionTo improve the clinical outcomes, perioperative risk should be comprehensively evaluated and perioperative management strengthened in the elder patients with intertrochanteric fractures, especially those with advanced age, more combined diseases, and low albumin, for the high postoperative mortality.
