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.
ObjectiveTo evaluate the effectiveness of locking compress plate (LCP) for the treatment of aseptic diaphyseal humeral nonunions. MethodsBetween January 2006 and January 2012, 23 patients with aseptic diaphyseal humeral nonuninons were treated with LCP and autologous iliac crest bone graft, and the clinical data were retrospectively analyzed. There were 15 males and 8 females with the average age of 42.5 years (range, 28-60 years). The fracture located at left side in 11 cases and right side in 12 cases. The mechanism of the injury was traffic accident in 15 patients, and falling from height in 8 patients. Fracture was treated by internal fixation in 20 cases and external fixation in 3 cases. And 6 patients had open fractures and other 17 had close fractures. Based on the Weber-Cech classification, 6 cases were rated as atrophic nonunions, and 17 cases as hypertrophic nonuninons. Shoulder function was evaluated by Constant-Murley score and elbow function was evaluated by Mayo score. ResultsAfter operation, 2 patients had transient radial nerve symptoms of numbness and 1 patient had superficial infection. Primary healing of incision was obtained in the other patients. All patients were followed up 22.22 months on average (range, 16-30 months). Normal range of motion of the shoulder was found in 11 cases; and limited movements of abduction, elevation, and posterior extension were observed in 12 cases. And osseous union was observed clinically and radiographically in all patients. The average union time was 16.95 weeks (range, 12-24 weeks). The average Constant-Murley score was 81.87 (range, 50-98); and shoulder function was excellent in 14 cases, good in 6, and fair in 3. And the average Mayo score was 87.78 (range, 70-96); and the result was excellent in 14 cases, good in 7, and fair in 2. ConclusionAseptic diaphyseal humeral nonunions can be successfully treated with LCP, coupled with the use of autologous iliac crest bone graft.
