Objective To discuss the relationship between recovery of anatomical integrity and functional outcome in elderly patients with distal radius fractures by comparing the effects of open reduction and closed reduction. Methods The cl inical data were retrospectively analyzed from 78 elderly patients with distal radius fractures treating with nonoperation andoperation from February 2005 to March 2009. Thirty-seven patients underwent closed reduction and spl intlet fixation or cast appl ication (non-operation group), and forty-one patients underwent open reduction and internal fixation (operation group). In non-operation group, there were 15 males and 22 females with an average age of 73 years (60-83 years). According to the AO classification system for fracture, there were 8 cases of type A2, 7 cases of type A3, 7 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1, 2 cases of type C2, and 3 cases of type C3. The time from injury to admission was between 30 minutes and 3 days with a mean time of 1 day. In operation group, there were 18 males and 23 females with an average age of 71 years (62-80 years). According to the AO classification system for fracture, there were 5 cases of type A2, 7 cases of type A3, 7 cases of type B1, 6 cases of type B2, 3 cases of type B3, 4 cases of type C1, 5 cases of type C2, and 4 cases of type C3. The time from injury to admission was between 30 minutes and 7 days with a mean time of 1 day. There were no significant differences (P gt; 0.05) in sex, age, disease course and fracture classification between two groups. Results All incisions obtained heal ing by first intention after operation in operation group. All patients were followed up for 9-36 months (20 months on average). Fracture heal ing was achieved within 8 to 15 weeks, with an average of 11 weeks. There were no significant differences (P gt; 0.05) in fracture heal ing time between non-operation group [(10.8 ± 2.0) weeks] and operation group [(11.7 ± 2.5) weeks]. At last follow-up, thepalmar tilt angle was (5.6 ± 2.0)° and (8.6 ± 3.0)°, the radial incl ination angle was (19.1 ± 4.9)° and (21.8 ± 2.0)°, and the radial length was (8.3 ± 1.3) mm and (10.4 ± 1.4) mm in non-operation group and operation group, respectively; showing significant differences (P lt; 0.05) between two groups. According to the Gartland-Werley score, the results were excellent in 9 cases, good in 21 cases, fair in 5 cases, and poor in 2 cases in non-operation group, the excellent and good rate was 81.1%; in operation group, the results were excellent in 13 cases, good in 25 cases, fair in 2 cases, and poor in 1 case, the excellent and good rate was 92.7%, showing no significant difference (P gt; 0.05) between two groups. There were no significant differences (P gt; 0.05) in flexion and extension activity of wrist, radioulnar partial activity, pronation-supination activity, grip and pinch strength between two groups. Conclusion Open reduction and closed reduction can achieve satisfactory functional outcomes, but closed reduction was inferior to open reduction in anatomic reduction for treating distal radius fractures in elderly patients.
ObjectiveTo study intraoperative reduction strategy in treatment of femoral neck fracture using cannulated screw fixation and the relationship between excellent and good rate of reduction and postoperative effectiveness. MethodsA retrospective analysis was made on the clinical data of 174 cases of femoral neck fracture treated between August 2005 and March 2015. There were 78 males and 96 females with an average age of 53.8 years (range, 23-75 years). The injury causes were falling in 85 cases, traffic accident in 61 cases, and falling from height in 28 cases. According to Garden typing, there were 35 cases of type I, 56 cases of typeⅡ, 47 cases of typeⅢ, and 36 cases of typeⅣ. The time from injury to operation was 1-7 days (mean, 2.74 days). Based on reduction strategy, closed 3 hollow compression screws were used; evaluating standards for fracture reduction effect were also established. Harris score was used for effectiveness evaluation. ResultsAll the cases received follow-up of 12-42 months (mean, 36.5 months). Bone healing was obtained in 152 cases at 6-12 months (mean, 9 months). Non-union and internal fixation failure occurred in 9 and 3 patients respectively, who underwent hemiarthroplasty; femoral head necrosis occurred in 6 patients after removing internal fixator at 15-26 months (mean, 18.5 months) after operation, who underwent total hip arthroplasty; 4 patients with non-union received vascular pedicle iliac flap transplantation. No other serious complications were observed. At last follow-up, the excellent and good rate of reduction was 94.29% for Garden type I, 91.07% for typeⅡ, 87.23% for typeⅢ, and 75.00% for typeⅣ, with a total excellent and good rate of 87.36%; the excellent and good rate of Harris score was 97.14% for Garden type I, 78.57% for typeⅡ, 68.09% for typeⅢ, and 50.00% for typeⅣ, with a total excellent and good rate of 73.56%. ConclusionTo obtain high Harris score in fixation of femoral neck fractures by using hollow screws, surgeons not only need reasonable technology, but also follow correct and good reduction strategy and assessment, fracture complexity is inversely proportional to excellent and good rate of reduction. Higher excellent and good reduction rate of complexity fracture should be obtained as much as possible in order to achieve good prognosis.
Objective To investigate the effectiveness of modified percutaneous suture in repairing acute closed Achilles tendon rupture by comparing with conventional open suture. Methods Between January 2006 and October 2009, 50 patients with acute closed Achilles tendon rupture were treated with modified percutaneous suture by making 5 small incisions at both sides of Achilles tendon and zigzag suture (improved group, n=22) and with Kessler suture (conventional group, n=28), respectively. No significant difference was found in gender, age, time from injury to operation between 2 groups (P gt; 0.05). Results In improved group, the patients achieved healing of incisions by first intention after operation and nocomplication occurred; however, incision infection occurred in 1 case, Achilles tendon re-rupture in 1 case, and incision scar contracture in 2 cases in conventional group. The operation time of improved group [(38.7 ± 6.6) minutes] was significantly shorter (t= —12.29, P=0.00) than that of conventional group [(52.3 ± 6.9) minutes]; the blood loss of improved group [(4.9 ± 2.0) mL] was significantly less (t= —25.20, P=0.00) than that of conventional group [(40.7 ± 7.1) mL]. The patients were followed up 2-3 years (mean, 29.9 months). The American Orthopaedic Foot and Ankle Society (AOFAS) score was 99.6 ± 1.0 in improved group and was 98.4 ± 3.0 in conventional group, showing no significant difference between 2 groups (t=1.66, P=0.10). Conclusion Comparison with conventional open suture, modified percutaneous suture has some advantages, such as easy operation, less complications, rapid recovery of limb function, and so on. Modified percutaneous suture is one of the best choices for the treatment of acute closed Achilles tendon rupture.
Objective To evaluate the effect of associated ulnar styloid fracture on wrist function after distal radius fracture by comparing the cl inical data between the cases of distal radius fracture with or without ulnar styloid fractures. Methods The cl inical data of 182 patients with distal radius fracture between February 2005 and May 2010 were retrospectively analyzed, including 75 with ulnar styloid fracture (group A), and 107 without ulnar styloid fracture (group B). There was no significant difference in sex, age, disease duration, and fracture classification between 2 groups (P gt; 0.05). In groups A and B, closed reduction and spl intlet or cast fixation were performed in 42 and 63 cases respectively, and openreduction and internal fixation in 33 and 44 cases respectively. All ulnar styloid fractures were not treated. Results Thepatients were followed up 21 months on average in group A and 20 months on average in group B. All incisions healed by first intention after operation. Ulnar wrist pain occurred in 4 patients (5.3%) of group A and 6 patients (5.6%) of group B, showing no significant difference (χ2=0.063, P=0.802). The fracture heal ing time was (10.9 ± 2.7) weeks in group A and (11.6 ± 2.3) weeks in group B, showing no significant difference (t=1.880, P=0.062). There was no significant difference in the palmar tilt angle, the ulnar incl ination angle, and the radial length between groups A and B when fracture healing (P gt; 0.05). At last follow-up, there was no significant difference in wrist flexion-extension, radial-ulnar deviation, pronation-supination, and grip and pinch strength between 2 groups (P gt; 0.05). According to the Gartland-Werley score in groups A and B, the results were excellent in 24 and 35 cases, good in 43 and 57 cases, fair in 5 and 10 cases, and poor in 3 and 5 cases with execllent and good rate of 89.3% and 86.0%, respectively, showing no significant difference between 2 groups (Z= —0.203, P=0.839). There were significant differences in the above indexes between patients undergoing closed reduction and open reduction in group A (P lt; 0.05). Conclusion Associated ulnar styloid fracture has no obvious effect on the wrist function after distal radius fracture. The anatomical reduction of distal radial fracture is the crucial importance in the treatment of distal radial fracture accompanying ulnar styloid fracture.
Objective To describe a surgical device for closed reduction of tibial fracture and investigate its clinical effectiveness. Methods Between June 2010 and December 2012, 24 cases of tibial fractures were treated with intramedullary nailing using a surgical device for closed reduction. There were 18 males and 6 females with an average age of 40 years (range, 20-64 years). All fractures were closed. There were 3 proximal third fractures, 12 middle third fractures, and 9 distal third fractures. According to AO classification, 12 cases were classified as type A, 8 cases as type B, and 4 cases as type C. The mean time between injury and operation was 3 days (range, 1-12 days). The intraoperative fluoroscopy frequency to confirm closed reduction and guide wire passing the fracture site, and the duration between fracture reduction and nail insertion were recorded. The injured limb alignment and fracture angular deformity were measured as described by Freedman et al. The fuction of affected limb was estimated by Johner-Wruhs criteria. Results Closed reduction was successfully performed in 24 patients. The mean fluoroscopy frequency to confirm closed reduction was 3 (range, 2-5). The fluoroscopy frequency to confirm guide wire passing the fracture site was 2. The mean duration between fracture reduction and nail insertion was 30 minutes (range, 20-42 minutes). No intraoperative or postoperative complication occurred, such as infection, vessel and nerve injuries. All incisions healed by first intention. Seventeen patients were followed up 6-16 months (mean, 10 months). Radiographic evidence showed that bridging callous was observed at 2-4 months (mean, 2.5 months). The injured limb alignment was normal on anteroposterial and lateral radiographs at 5 months postoperatively, no malalignment and obvious angular deformity was observed. The internal fixator had good position. According to Johner-Wruhs criteria for evaluation of the affected limb function, the results were excellent in 12 cases and good in 5 cases with an excellent and good rate of 100%. Conclusion The surgical device for closed reduction of tibial fracture is simple and easy to use, and has good effectiveness combined with intramedullary nailing.
ObjectiveTo systematically review the efficacy of closed and open tracheal suction system on the prevention of ventilator-associated pneumonia.MethodsThe Cochrane Library, CNKI, WanFang Data, Airiti Library, PubMed, CINAHL and Proquest databases were electronically searched to collect randomized controlled trials (RCTs) on closed and open tracheal suction system on the prevention of ventilator-associated pneumonia. Two reviewers independently screened literature, extracted data, and assessed the risk bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 11 RCTs involving 1 187 patients were included. The results of meta-analysis showed that compared with open tracheal suction system, closed tracheal suction system was associated with a reduced incidence of ventilator-associated pneumonia (RR=0.55, 95%CI 0.44 to 0.67, P<0.000 01), late-onset ventilator-associated pneumonia (RR=0.47, 95%CI 0.28 to 0.80, P=0.005), length of stay in intensive care unit (MD=?0.85, 95%CI ?1.66 to ?0.04, P=0.04) and rate of microbial colonization (RR=0.69, 95%CI 0.56 to 0.86, P=0.000 9). However, there were no significant differences between two groups in time to ventilator-associated pneumonia development (MD=0.96, 95%CI ?0.21 to 2.12, P=0.11), length of mechanical ventilation (MD=?2.24, 95%CI ?4.54 to 0.06, P=0.06), and rate of mortality (RR=0.88, 95%CI 0.73 to 1.05, P=0.15).ConclusionsCurrent evidence shows that compared with open tracheal suction system, closed tracheal suction system can reduce the incidence of ventilator-associated pneumonia and late-onset ventilator-associated pneumonia, shorten the hospital stay in intensive care unit, and reduce rate of microbial colonization. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To introduce the method and effect of common cardiop ulmonary bypass(CPB) switched to closed extracorporeal circulation by medtronic extracorporeal membrane oxygenation(ECMO) package. Methods From Junuary 2007 to June 2008, common CPB switched to closed extracorporeal circulation by Medtronic ECMO package adding blood reservoir and artery microembolus filtrator was used to 15 patients with grave heart disease to provide CPB support during operation on heart and cardiac function support after operation. The circulation was built through femoral arteryfemoral veinsuperior vena cava intubation or aortaright auricle intubation. There were 10 male and 5 female aged from 6582 years (74.0±9.3 years) and weighed from 6389 kg (69.0±11.4 kg). There were 11 cases with old myocardial infarction, 1 case with acute myocardial infarction, 1 case with old myocardial infarction complicated with mitral stenosis and mitral incompetence, and 2 cases reopened and undergone double valve replacement. Results For all the 15 patients, the closed circulation time was 31112 min（77.3±21.5 min）. The CPB time was 51-84 min（69.7±9.8 min）. The ostoperative mechanical ventilation time was 414 h（8.3±2.9 h）. The 24 hchest drainage was 110-360 ml（227.3±80.4 ml）. All patients were cured and discharged successfully with cardiac function classification in grade ⅠⅡ. Thirteen cases were followed up. The followup time was 412 months. Their cardiac function recovered well and no complication occurred. Conclusion This method could provide effective support for heart and lung before operation，during operation and after operation. This method could save material cost. The heparin paintcoat could reduce inflammatory reaction and it is good for patients’ recovery.
Objective To explore the surgical method and cl inical short-term outcomes of internal fixation combined closed reduction with arthroscope aid in treating patellar fracture. Methods From June 2004 to July 2008, 42 patients with fresh simple patellar fracture underwent internal fixation combined closed reduction with arthroscope aid, included28 males and 14 females, aged 16-59 years (35 years on average). The locations were 19 left knees and 23 right knees. Injury was by traffic accident in 21 cases, by fall ing in 11 cases, by sports in 7 cases and by crush in 3 cases. All the patients had fresh closed fracture, including 38 cases of transverse fracture and 4 cases of stellate fracture. The Lysholm score was 68.60 ± 15.20; the proprioceptive function of the knee joints was (3.72 ± 0.12)°. The time from injury to operation was 3-42 hours (12 hours on average). After the treatment of affil iated injury under the arthroscope, patellar fracture was reduced with manipulation method, fracture was fixed with tensile force screw or modified tension band. Results All incisions obtained heal ing by first intention after operation, 42 patients were followed up for 12-39 months (16 months on average). The X-ray films showed callus at the fracture and the smooth cartilage surface 6-9 weeks (7 weeks on average) after operation. The flexed motion range of knee joint at last follow-up was at normal range in 38 cases, was l imited in 4 cases. Circumference of suffered l imbs 15 cm above the patella was the same as normal ones in 23 cases, atrophied 0.7 cm in 19 cases. There were no breakage of internal fixation and shift of fracture and patellofemoral arthritis at last follow-up. The proprioceptive function of the knee joints was (2.06 ± 0.11)° and the Lysholm score was 95.10 ± 3.92; all showing statistically significant differences when compared with preoperation (P lt; 0.05). Conclusion This treatment method has advantages as follows: mini-wound, early exercises and few compl ications, which can rinse articular cavity and repair the affil iated injury at the same time.
【Abstract】 Objective To discuss the techniques and advantages of closed reduction and intramedullary nail ing intreating femoral shaft fracture without cannulated femoral reamer. Methods From January 2006 to June 2007, 24 cases offemoral shaft fracture were treated with closed reduction and intramedullary nail ing. Among them, there were 14 males and 10 females, with the average age of 38.3 years (ranging from 18 years to 63 years), with 7 left legs and 17 right legs. The average course of the disease was 7.6 days (ranging from 3 days to 20 days). According to the AO typing, there were 5 cases of type A, 6 of type B, 7 of type C1, 2 of type C2 and 4 of type C3. Closed reduction was achieved with manipulation and reaming of femoral canal was instructed by fluoroscopy. Results The operation time lasted from 100 minutes to 170 minutes, with the average time of 128.3 minutes. One patient was given a transfusion of 400 mL, and others were not. Twenty cases were followed up with the average time of 13.1 months (ranging from 6 months to 24 months). A mild to large amount of bony callus was showed on X-ray films 6 to 12 weeks postoperatively. Walking without crutches began at the average week of 22.2 (ranging from 15 to 30) postoperatively. Range of motion of the knee was 0° to 145.5°. No infection or break of the internal fixator occurred. Myositis ossificans with pain and insufficient flexion of hip (120°) happened in 1 case and the pain disappeared after non-steroid anti-inflammatory drugs were taken. Nonsymptomatic myositis ossificans occurred in 2 cases and no treatment was needed. Conclusion Closed reductionand intramedullary nail ing can help to protect the blood supply of fracture fragments and provide central fixation. The operation process will be more compl icated if cannulated femoral reamer is not available.
