Objective To investigate the operative procedure and the therapeutic effects of unstable femoral intertrochanteric fracture in elderly patients with rebuild septum bronchiale in artificial femoral head replacement. Methods From October 2005 to October 2007, 113 elderly patients with unstable femoral intertrochanteric fracture were treated with artificial femoral head replacement with fixation of femoral greater trochanter and smaller trochanter in the help of bone cement in 58 cases (test group) and with γ-type bone nail in 55 cases (control group). In test group, there were 21 males and 37 females with an average age of 75 years, including 10 cases of type IIIA, 16 cases of type IIIB and 32 cases of type IV according to Evans-Jenson standard. In control group, there were 17 males and 38 females with an average age of 72.5 years,including 13 cases of type IIIA, 14 cases of type IIIB and 28 cases of type IV according to Evans-Jenson standard. All fractures were caused by fall damage. The disease course was 3 hours to 7.5 days (mean 1.4 days). The patients of two group compl icated with osteoporosis, and compl icated by one or several compl ications of coronary heart disease, hypertension, diabetes and chronic bronchitis. And all patients did not had fracture at other sites. There was no significant difference in general data between two groups (P gt; 0.05). Results The operations were successful, the incision healed by first intention. There were significant differences in operation time, operative blood loss and blood-transfusion between two groups (P lt; 0.05). The two group were followed 12-36 months. There were significant differences (P lt; 0.05) in the incidence rate of compl ication and the excellent and good rate of hip function (by Harris standard) between the test group (3.4% and 93.1%) and the control group (16.4% and 70.9%) 12 months after operation. Conclusion The aged patients with intertrochanteric fracture can get good result through caput femoris replacement, and rebuild septum bronchiale is of great significance.
ObjectiveTo analyze the associated risk factors of hidden blood loss in the internal fixation of intertrochanteric fracture. MethodsA retrospective analysis was made on the clinical data of 317 cases of intertrochanteric fractures which were treated by internal fixation between January 1993 and December 2008. There were 154 males and 163 females with an average disease duration of 4.58 days (range, 7 hours to 33 days); the age was (69.86±15.42) years; the average height was 1.64 m (range, 1.50-1.84 m);and the average weight was 62.26 kg (range, 39-85 kg). Of them, intramedullary fixation was used in 203 patients and extramedullary fixation in 114 patients. The operation time was (61.99±18.25) minutes. The red blood cell transfusion was given to 84 patients, and the transfusion amount was 200-1 000 mL. The drainage volume was 0-750 mL (mean, 61.85 mL). Hidden blood loss was calculated through change of hematocrit level before and after operation. The multiple linear regression was performed to analyse the risk factors of hidden blood loss. ResultsThe total blood loss was (918.60±204.44) mL, the hidden blood loss was (797.77±192.58) mL, and intraoperative visible blood loss was (257.32±271.24) mL. Single factor analysis showed hidden blood loss was significantly higher in variables as follows:gender, age, injury cause, fracture type, American anesthesiologists grading, anesthesia mode, hypertension, diabetes, disease duration, operation time, intraoperative transfusion of red blood cells, and fixation type. Multiple linear regression showed age, fracture type, anesthesia mode, and fixation type were significant risk factors. ConclusionThe risk factors of hidden blood loss are advanced age (>60 years), unstable fracture, general anesthesia, and imtramedullary fixation. Especially in elder patients with unstable fracture treated by intramedullary fixation under general anesthesia, hidden blood loss is more significant.
Objective To investigate the appl ication of anti-rotation screw after dynamic hi p screw (DHS) in treatment of intertrochanteric fracture. Methods Between April 2006 and January 2010, 22 cases of intertrochanteric fractures underwent DHS fixation operation with an anti-rotation screw, including 15 males and 7 females with an average ageof 66.3 years (range, 54-83 years). Fractures were caused by sl ipping in 16 cases, traffic accident in 5 cases, and fall ing from height in 1 case. All cases showed closed fractures, including 13 cases in the left and 9 cases in the right. Eighteen cases were simple intertrochanteric fracture, 4 cases were intertrochanteric fractures compl icated with Colles fractures. According to Evans classification standard, there were 14 cases of type I, 6 cases of type II, 1 case of type III, and 1 case of type IV. The time from wound to operation was 3-7 days (mean, 4.5 days). Results The operation time ranged from 51-95 minutes (mean, 72 minutes). The intraoperative blood loss was 150-350 mL (mean, 270 mL). The hospital ization days were 12-35 days (mean, 16.8 days). Primary heal ing was observed in all cases. All cases were followed up 6-17 months (mean, 14 months). Union of fracture was observed at 12-16 weeks (mean, 13.6 weeks); no fracture or internal fixation loosening occurred. According to HUANG Gongyi’s standard of efficacy assessment, the results were excellent in 19 cases and good in 3 cases. Conclusion Appl ication of an anti-rotation screw can help to improve the strength of the DHS for the internal fixation of intertrochanteric fracture, especially the anti-rotation abil ity, which does not increase the operation time obviously.
ObjectiveTo analyze the effectiveness of fast track protocol of geriatric intertrochanteric fracture on operative waiting time, operation time, perioperative blood loss, providing data support for clinical therapy.MethodsThe clinical data of 240 elderly patients with intertrochanteric fracture admitted between January 2015 and December 2018 were retrospectively analyzed. They were divided into traditional protocol group (148 cases, group A) and fast track group (92 cases, group B). All patients were treated with closed reduction intramedullary nail (proximal femoral nail antirotation) surgery. There was no significant difference in gender, age, sides, fracture classification, fracture type, complications, the proportion of patients with more than 3 kinds of medical diseases, and the time from injury to admission between the two groups (P>0.05). Analysis index included operative waiting time (hospitalization to operation time), operation time, percentage of operation performing in 48 and 72 hours, percentage of transfusion, changes of hematocrit (Hct) at different stage (admission, operation day, and postoperative 1, 3 days), blood loss by fracture and cephalomedullary nail, intraoperative dominant blood loss, total blood loss in perioperative period were recorded and compared.ResultsThe operative waiting time, operation time, Hct on operation day and postoperative 3 days, blood loss by fracture, transfusion volume, and total blood loss in perioperative period in group B were significantly less than those in group A (P<0.05), and the percentage of operation performing in 48 and 72 hours in group B were significantly higher than those in group A (P<0.05). There was no signifcant difference in Hct on admission and postoperative 1 day, intraoperative dominant blood loss, percentage of transfusion, blood loss by cephalomedullary nail between the two groups (P>0.05).ConclusionFast track can shorten the operative waiting time of geriatric intertrochanteric fracture, reduce the blood loss by fracture, total blood loss in perioperative period, and transfusion volume. Early operation is conducive to improve the anemia status of patients during perioperative period.
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.
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.
Objective To confirm the association between tail femur distance (TFD) and lag screw migration or cutting-out in the treatment of intertrochanteric fracture with the third generation of Gamma nail (TGN). Methods The clinical data of 124 cases of intertrochanteric fracture treated with TGN internal fixation and followed up more than 18 months between January 2012 and December 2015 were reviewed and analyzed. There were 52 males and 72 females, with an age of 46-93 years (mean, 78.5 years). According to AO/Association for the Study of Internal Fixation (AO/ASIF) classification, 43 cases were type 31-A1, 69 cases were type 31-A2, and 12 cases were type 31-A3. The time from injury to operation was 1-10 days (mean, 2.9 days). According to the fracture healing of the patients, the patients were divided into the healing group and failure group. The age, gender, height, bone mineral density (BMD), fracture AO/ASIF classification, the time from injury to operation, and the TFD value at 1 day after operation were recorded and compared. The risk factors for the migration or cutting-out of lag screw were analyzed by logistic regression. Results There were 111 cases in healing group, the healing time was 80-110 days (mean, 95.5 days). There were 13 cases in failure group, including 2 cases of lag screw cutting-out and 11 cases of significant migration. Except for the TFD value at 1 day after operation in failure group was significantly higher than that in the healing group(t=5.14, P=0.00), there was no significant difference in gender, age, height, BMD, fracture of AO/ASIF classification, and the time from injury to operation (P>0.05) between 2 groups. logistic regression analysis showed that TFD value was a risk factor for the migration or cutting-out of lag screw (B=1.22, standardized coefficient=0.32, Wald χ2=14.66, P=0.00, OR=3.37). Conclusion The patients with higher TFD value had higher risk of postoperative lag screw migration or cutting-out. This result indicates that the appropriate length of the lag screw is helpful to reduce TFD value and prevent postoperative lag screw migration or cutting-out.
ObjectiveTo evaluate the effectiveness of the leverage reduction with proximal femoral nail antirotation (PFNA) ball head screw driver for difficult-reducing intertrochanteric fracture.MethodsThe clinical data of 8 patients with difficult-reducing intertrochanteric fractures between July 2015 and February 2018 were retrospectively analysed. There were 3 males and 5 females, aged 66-89 years, with an average age of 76.3 years. According to Evans classification, there were 3 cases of type Ⅲ and 5 cases of type Ⅳ. The time from injury to operation was 2-8 days (mean, 3.9 days). All patients were reducted with ball head screw driver leverage through PFNA proximal incision during operation. The operation time, intraoperative blood loss, reduction time, and fluoroscopy times were recorded. Harris hip function score was used to evaluate the effectiveness at last follow-up.ResultsThe operation time was 52.5-83.7 minutes (mean, 68.1 minutes), the intraoperative blood loss was 49.8-96.4 mL (mean, 73.1 mL), the reduction time was 3.7-9.1 minutes (mean, 6.4 minutes), and the fluoroscopy times were 18.4-27.4 times (mean, 22.9 times). Patients were followed up 6-18 months (mean, 9.6 months). Postoperative X-ray films showed that the fracture obtained good reduction. No fracture displacement, fixation failure, and coxa vara occurred after operation. Fracture healing time was 3-6 months (mean, 4.6 months). At last follow-up, the Harris hip function score was 85-96 (mean, 91.6), with a result of excellent in 6 cases and good in 2 cases.ConclusionThe reduction of difficult-reducing intertrochanteric fracture by using ball head screw driver can obtain good reduction and reliable fixation. The method has such advantages as no more incision, and less blood loss and soft tissue injury.
ObjectiveTo measure the rotation angle of the head-neck fragment of intertrochanteric fracture after cephalomedullary nail fixation by three-dimensional CT imaging, and to explore its clinical significance.MethodsThe clinical data of 68 patients with unstable intertrochanteric fracture of AO/Orthopaedic Trauma Association (AO-OTA) type 31-A2 treated with cephalomedullary nail fixation and with complete intraoperative fluoroscopy and postoperative three-dimensional CT imaging data between July 2016 and October 2018 were retrospectively analyzed. Among them, there were 21 males and 47 females, aged 68-93 years, with an average age of 81.8 years. There were 31 cases of AO/OTA type 31-A2.2 and 37 cases of 31-A2.3. Fracture reduction quality was evaluated according to Baumgaertner et al. and Chang et al. criteria. The anteromedial cortical contact or not of each patient was observed by three-dimensional CT imaging on T3DView software after operation. The rotation of head-neck fragments were divided into three types: non-rotation, flexion rotation, and hyperextension rotation. The rotation angles of each type were measured and the relationship between the rotation type of the head-neck fragments and the contact of the anteromedial cortex was analyzed.ResultsThe reduction and fixation of the small trochanter were not performed in 68 patients. According to Baumgaertner et al. criteria, the quality of fracture reduction was excellent in 15 cases (22.1%), acceptable in 50 cases (73.5%), and poor in 3 cases (4.4%). According to Chang et al. criteria, 31 cases were excellent (45.6%), 33 cases were acceptable (48.5%), and 4 cases were poor (5.9%). Thirty-nine cases (57.4%) received anteromedial cortical support and 29 cases (42.6%) did not receive cortical support. Three-dimensional CT imaging showed non-rotation in 12 cases (17.6%), flexion rotation in 39 cases (57.4%), and hyperextension rotation in 17 cases (25.0%). There were 7 cases (58.3%), 30 cases (76.9%), and 2 cases (11.8%) of cortical support in non-rotation group, flexion rotation group, and hyperextension rotation group, respectively. The rotation angles were (1.05±0.61), (13.96±6.17), (8.21±3.88)°, respectively. There were significant differences between groups (P<0.05).ConclusionIn the unstable intertrochanteric fracture after cephalomedullary nail fixation, the rotation of head-neck fragment exists in most patients, and the types of flexion rotation and non-rotation can easily obtain cortical support reduction.
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.
