Objective To compare the effectiveness of proximal femoral nail antirotation (PFNA) and reconstruction nail with minimally invasive technique for ipsilateral femoral shaft and extracapsular hip fractures in young and middle-aged patients. Methods Sixty-nine young and middle-aged patients with ipsilateral femoral shaft and extracapsular hip fractures were treated between January 2000 and August 2010, and their data were analyzed retrospectively. Of them, fractures were fixed by reconstruction nail in 44 cases (reconstruction nail group) and by PFNA in 25 cases (PFNA group). There was no significant difference in gender, age, weight, injury cause, fracture type, or disease duration between 2 groups (P gt; 0.05). The operation time, blood loss, fracture healing time, complications, and functional outcomes were compared between 2 groups to evaluate the effectiveness. Results The operation time and blood loss in the PFNA group were significantly less than those in the reconstruction nail group (P lt; 0.05). The follow-up time was 12-38 months (mean, 20 months ) in the PFNA group and was 12-48 months (mean, 22 months) in the reconstruction nail group. No complication occurred as follows in 2 groups: wound infection, deep venous thrombosis, pulmonary embolism, breakage of the implants, avascular necrosis of the femoral head, or serious rotation and shortening deformity of lower limbs. In the PFNA group and the reconstruction nail group, 1 patient underwent technical difficulty in nail implant and 7 patients underwent technical difficulty in proximal locking screw, respectively; 3 patients and 6 patients had intra-operative iatrogenic fracture of femoral shaft, respectively; and delayed union of femoral shaft was observed in 1 patient and 2 patients, respectively. The complication rate was 20% (5/25) in the PFNA group and 34% (15/44) in the reconstruction nail group, showing no significant difference (χ2=1.538, P=0.215). No significant difference was found in fracture healing time between 2 groups (P gt; 0.05). At last follow-up, there was no significant difference in Harris hip score and Evanich knee score between 2 groups (P gt; 0.05). Conclusion PFNA or reconstruction nail with minimally invasive technique is a good method to treat ipsilateral femoral shaft and extracapsular hip fractures, but the PFNA is superior to the reconstruction nail because of simple operation.
Objective To compare the risk of bone fractures in proton pump inhibitor users and nonusers, so as to evaluate the effects of proton pump inhibitors on the risk of bone fractures. Methods We searched PubMed, MEDLINE and EMbase databases to March 1st 2011 to identify case-control studies or cohort studies evaluating the risk of fracture in proton pump inhibitor users and nonusers. We conducted systematic review and meta-analysis according to the fracture site, duration of exposure, average daily dose and time of last use. Summary odds ratios (OR) and 95% confidence interval (CI) were calculated by RevMan 5.0.25 software. We also calculated and looked for heterogeneity. Results Eleven studies were identified from ten literatures, including seven case-control studies and four cohort studies. In case-control studies, the risk of total fractures increased by 36% in proton pump inhibitor users as compared with nonusers (OR=1.36, 95%CI 1.20 to 1.55). The risk of hip fracture increased by 39% (OR=1.39, 95%CI 1.13 to 1.71). In cohort studies, the risk of total fractures increased by 59% (OR=1.59, 95%CI 1.47 to 1.73). The risk of non-hip fractures increased by 65% (OR=1.65, 95%CI 1.47 to 1.85). As compared with nonusers, fracture risk increased by 41% in current users and by 38% in past users whose last use was at least 1 year ago. There was no significant difference between the two groups. Conclusion Proton pump inhibitors increase the risk of fracture to a certain degree. The effect does not fade away by discontinuation of PPI use for at least one year. Stricter clinical trials are needed to exclude confounding factors.

ObjectiveTo investigate the clinical features of elderly hip fracture in Leshan area in China. MethodsThe clinical data of patients with hip fractures from June 2006 to January 2013 were retrospectively analyzed. Gender, age, fracture type, injury causes, activities before injury and treatment were analyzed. ResultsThe mean age of patients with a hip fracture was 76.5 years. The overall male to female ratio with hip fracture was 1:1.44. There were 154 patients (50.0%) with femoral neck fracture, 138 patients (44.8%) with intertrochanteric fracture, and 16 patients (5.2%) with subrtrochanteric fracture. A total of 248 patients (77.3%) were poorly educated, and 210 patients (68.2%) had basic medical insurance. The mean time between being injured and hospitalized after injury was 3 days. There were 257 patients (83.4%) with fall damage. ConclusionFemale patients with hip fracture are more than male patients. Fall damage is the main injure type. The features of elderly hip fracture in Leshan include retardation to consult a doctor, poor education of the patients, dependence primarily on basic medical insurance and under-emphasis of anti-osteoporosis therapy.
ObjectiveTo introduce the clinical pathway for geriatric hip fracture regulated by our hospital and report the five-year outcomes after the implementation of the pathway. MethodsThe geriatric hip fracture patients treated between September 2003 and August 2012 were followed up. We did not implement the clinical pathway until January 2007. Statistical analysis was done to evaluate the effect of the clinical pathway on patient outcomes by comparing rate of complication, mortality, and length of hospital stay before and after the implementation of the clinical pathway. ResultsAfter the implementation of the pathway, the in-hospital mortality, one-year mortality and the rate of complication were significantly lower. Besides, the time from admission to operation and the total length of stay in hospital were obviously shortened. ConclusionThe use of clinical pathway for geriatric hip fracture can reduce the rate of complication and mortality, and shorten hospital stay, and the five-year outcomes after the implementation of the pathway are satisfying.
ObjectiveTo research on the condition of constipation during the first 30 days after hip fracture. MethodsOne hundred and four patients with hip fracture treated between May 2014 and March 2015 participated in this study. We judged whether there was constipation by recording the defecation pattern and stool consistency in three time periods: from admission to the time just before surgery, from the end of surgery to the time of discharge, and from discharge to 30 days after injury. The defecation pattern was assessed using Bristol Stool Scale and a scale of four-stage defecation was used to assess the stool consistency. ResultsThere were 51.9% (54) of the patients who developed constipation during the first time period, 69.0% (69) during the second time period, and 63.4% (59) in the third time period. The proportion increased by 17% during the second period over the first (P=0.003), while there was no significant difference between the latter two time periods (P=0.581). Normal defecation pattern was re-established 9.7 days after surgery, though 23.7% (22) of the patients did not re-establish normal defecation pattern within the first 30 days after injury. ConclusionThe incidence of constipation during the first 30 days after hip fracture is high. The results imply that further studies are needed to prevent constipation.
ObjectiveTo analyze the correlation between the trabecular microstructure and the clinical imaging parameters in the fracture region of osteoporotic hip so as to provide a simple method to evaluate the trabecular microstructure by a non-invasive way. MethodsBetween June 2012 and January 2013, 16 elderly patients with femoral neck fracture underwent hip arthroplasty were selected as the trial group; 5 young patients with pelvic fracture were selected as the control group. The hip CT examination was done, and cancellous bone volume/marrow cavity volume (CV/MV) was analyzed with Mimics 10.01 software in the control group. The CT scan and bone mineral density (BMD) measurement were performed on normal hips of the trial group, and cuboid specimens were gained from the femoral necks at the place of the tensional trabeculae to evaluate the trabecular microstructure parameters by Micro-CT, including bone volume fraction (BV/TV), trabecular number (Tb. N), trabecular spacing (Tb.Sp), trabecular thickness (Tb.Th), connect density (Conn.D), and structure model index (SMI). The correlation between imaging parameters and microstructure parameters was analyzed. ResultsIn the trial group, the BMD value was 0.491-0.698 g/cm2 (mean, 0.601 g/cm2); according to World Health Organization (WHO) standard, 10 cases were diagnosed as having osteoporosis, and 6 cases as having osteopenia. The CV/MV of the trial group (0.670 1±0.102 0) was significantly lower than that of the control group (0.885 0±0.089 1) (t=-4.567, P=0.000). In the trial group, CV/MV had correlation with BV/TV, Tb.Th, and SMI (P<0.05); however, CV/MV had no correlation with Tb.N, Tb.Sp, or Conn.D (P>0.05). BV/TV had correlation with Tb.Th, Tb.N, Tb.Sp, and SMI (P<0.05), but it had no correlation with Conn.D (P=0.075). There was no correlation between BMD and microstructure parameters (P>0.05). ConclusionCV/MV obviously decreases in the osteoporotic hip, and there is a correlation between CV/MV and the microstructure parameters of BV/TV, Tb.Th, and SMI, to some extent, which can reflect the variety of the microstructure of the trabeculae. There is no correlation between BMD of femoral neck and microstructure parameters.
ObjectiveTo explore the impact of perioperative average blood-glucose level on the prognosis of patients with hip fracture and diabetes mellitus. MethodsA retrospective analysis was made on the clinical data of 244 patients with hip fracture and diabetes mellitus who accorded with the inclusion criteria between September 2009 and September 2012.Of 244 patients,125 patients with poorly controlled fasting blood-glucose (average fasting blood-glucose level >7.8 mmol/L) were assigned in group A,and 119 patients with well controlled fasting blood-glucose (average fasting blood-glucose level ≤7.8 mmol/L) were assigned in group B according to "China guideline for type 2 diabetes" criteria.There was no significant difference in gender,age,disease duration of diabetes mellitus,serum albumin,fracture type and disease duration,surgical procedure,anaesthesia,and complications between 2 groups (P>0.05).Group A had a higher hemoglobin level and fewer patients who can do some outdoor activities than group B (t=-2.353,P=0.020;χ2=4.333,P=0.037).The hospitalization time,days to await surgery,stitch removal time,the postoperative complication rate,the mortality at 1 month and 1 year after operation,and ambulatory ability at 1 year after operation were compared between the 2 groups. ResultsA total of 223 patients (114 in group A and 109 in group B) were followed up 12-15 months (mean,13.5 months).The days to await surgery of group A were significantly more than those of group B (t=-2.743,P=0.007),but no significant difference was found in hospitalization time and stitch removal time between 2 groups (P>0.05).The postoperative complication rate of group A (19.2%,24/125) was significantly higher than that of group B (8.4%,10/119)(χ2=5.926,P=0.015).Group A had a higher mortality at 1 month after operation than group B (6.1% vs.0)(χ2=5.038,P=0.025),but no significant difference was shown at 1 year after operation between groups A and B (8.8% vs.4.6%)(χ2=1.555,P=0.212).At 1 year after operation in patients who can do some outdoor activities,the proportions of patients who turned to do some indoor activities was 19.2%(15/78) in the group A and 13.5%(12/89) in group B,showing no significant difference (χ2=1.013,P=0.314). ConclusionPoorly controlled perioperative fasting blood-glucose may lead undesirable influence on the prognosis of patients with hip fracture and diabetes mellitus.In order to reduce the complication rate and other accidents,the fasting blood-glucose level should be controlled to 7.8mmol/L or less.
