ObjectiveTo explore the effectiveness difference between titanium elastic intramedullary nail internal fixation and bone plate internal fixation in the treatment of adult Galeazzi fracture.MethodsNinety-seven patients of Galeazzi fracture according with the selection criteria were divided into 2 groups by prospective cohort study, who were admitted between January 2012 and November 2015. In the patients, 59 were treated with open reduction and bone plate internal fixation (plate group), and 38 with titanium elastic intramedullary nail internal fixation (minimally invasive group). There was no significant difference in the gender, age, cause of injury, fracture site, type of fracture, and time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were recorded and compared between 2 groups, and the forearm function was evaluated by Anderson score.ResultsAll the patients were followed up 12-23 months (mean, 17 months). The operation time, intraoperative blood loss, fracture healing time of minimally invasive group were significantly less than those in plate group (P<0.05). There were 1 case of fracture nonunion, 1 case of wound infection in plate group, and 1 case of nail tail slight infection in minimally invasive group, which were all cured after the corresponding treatment. The remaining patients had good fracture healing, and no vascular injury, internal fixation failure, deep infection, or other complications occurred. According to Anderson score at 12 months after operation, the forearm function results were excellent in 46 cases, good in 12 cases, and poor in 1 case, with an excellent and good rate of 98.3% in plate group; and the results were excellent in 26 cases, good in 11 cases, and poor in 1 case, with an excellent and good rate of 97.4% in minimally invasive group; showing no significant difference (χ2=0.10, P=0.75).ConclusionMinimally invasive fixation with titanium elastic nail has such advantages as small damage, quick recovery, no skin scarring, etc. As long as the correct indication is selected, minimally invasive titanium intramedullary nail internal fixation of Galeazzi fractures can also get good effectiveness.
【Abstract】 Objective To explore the effectiveness of bone grafting by intervertebral disc endoscope for postoperativenonunion of fracture of lower limb. Methods Between August 2004 and August 2008, 40 patients (23 males and 17 females) with postoperative nonunion of femoral and tibial fracture, aged 20-63 years (mean, 41.5 years) were treated. Nonunion of fracture occurred at 10-16 months after internal fixation. During the first operation, the internal fixation included interlocking intramedullary nail ing of femoral fracture in 12 cases and plate in 16 cases, and interlocking intramedullary nail ing of tibial fractures in 9 cases and plate in 3 cases. The X-ray films showed hypertrophic nonunion in 24 cases, common nonunion in 3 cases, and atrophic nonunion in 13 cases. Results The average operation time was 61 minutes (range, 40-80 minutes), and the blood loss was 80-130 mL (mean, 100 mL). The hospital ization time were 6-11 days (mean, 8.1 days). Incisions healed by first intention in all patients with no complication of infection or neurovascular injury. Forty patients were followed up 10-16 months (mean, 12.3 months). The X-ray films showed that all patients achieved healing of fracture after 4-10 months (mean, 6.8 months). No pain, disfunction, or internal fixation failure occurred. Conclusion Bone grafting by intervertebral disc endoscope is an effective method for treating postoperative nonunion of femoral and tibial fracture.
Objective To evalute the cl inical outcomes of two different surgical treatments for arachnoid cysts in sacral canal. Methods From January 2004 to March 2009, 55 cases of arachnoid cysts in the sacral canal were treated by traditonal simple sacral laminectomies with resection of the cysts (group A, 25 cases) and novel CT-guided percutaneous fibrin glue therapy of arachnoid cysts (group B, 30 cases). Of them, there were 23 males and 32 females, aging 15-66 years with an average of 42.6 years; the duration of symptoms was 6 months to 15 years with an average of 3.5 years. L5-S1 was involved in 22 cases, S1,2 in 25 cases, S2,3 in 12 cases, S2 in 8 cases, and presacral in 2 cases. The size of cysts was 1.5 cm × 1.0 cm to 6.0 cm × 2.8 cm. The MRI examination showed that all patients had cysts in the sacral canal. There were no significant difference (P gt; 0.05) in sex, ages, disease duration and cysts size between two groups. Preoperative data and postoperative lumbosacral pain and function improvement were analyzed and compared between two groups. Results All operations were performed successfully. The operative time, blood loss and hospital ization days of group B were significantly less than those of group A (P lt; 0.01). All 55 cases were followed up from 9 to 61 months (mean 23 months). In group A, postoperative cerebrospinal fluid leakage (25 cases), intracranial infection (2 cases), nerve injury (3 cases), and nerve root irritation (8 cases) occurred; in group B, mild meningitis (3 cases) and low grade fever (5 cases) occurred. Except for nerve injury, other compl ications were cured after symptomatic management. During the follow-up, 2 recurrent cases were found in group A and 1 case in group B. Of them, 2 recurrent cases were treated with CT-guided percutaneous fibrin glue therapy of arachnoid cysts, and cysts disappeared. For two groups, there were significant differences in Oswestry functional disabil ity index and visual analogue scale score between preoperation and postoperation (P lt; 0.01), and in the rate of score improvement between two groups (P lt; 0.01). According to the rating scale, the excellent and good rates of pain improvement were 64% in group A and 100% in group B; the excellent and good rates of function improvement were 24% in group A and 97% in group B. Conclusion CT-guided percutaneous fibrin glue therapy for arachnoid cysts in the sacral canal is a mini-invasive, safe, effective, and economical method, it may be better choices for the treatment of arachnoid cysts in the sacral canal.
Objective To explore and summarize the application of minimally invasive technique to every stage of severe acute pancreatitis (SAP). Methods The treatment of 101 SAP patients admitted to our hospital between January 1995 and December 2008 were retrospectively analyzed. After calculi were removed by endoscopic retrograde cholangiopancreatograpy (ERCP) and endoscopic sphincterotomy (EST), endoscopic nasobiliary drainage (ENBD) were applied, then rhubarb liquid was perfused into gut with a nutrient canal and ultrasound-guided abdominal drainage tube were simultaneously placed at the early stage. Some patients received continuous renal replacement therapy (CRRT) at the same time. Laparoscopic cholecystectomy (LC) was performed at the subacute stage, and choledochoscope was introduced to remove parapancreatic necrotic tissues at the late stage of SAP.Results Of all the 101 cases treated by the method mentioned above, 75 cases received ERCP (or EST) and ENBD, and 31 cases underwent rhubarb liquid perfusion with a nutrient canal. Eight cases underwent continuous renal replacement therapy (CRRT). Forty-eight cases underwent LC and ultrasoundguided abdominal drainage. Thirtysix cases with infected peripancreatic tissue or abscess underwent debridement under choledochoscope 3 to 14 times at the later stage. Five cases died of multiple organ failure (MOF) and acute respiratory distress syndrome (ARDS). The hemobilia ocurred in 2 patients during choledochoscopy and was cured under direct visualization by electric coagulation. Intestinal fistula happened in 3 cases and cured by drainage. Pancreatic pseudocyst was latterly seen in 3 cases and treated by the anastomosis of cyst with jejunum through selective operation. After the hospitalization of 9-132 d (mean 24 d), 96 cases completely recovered. Conclusion Timely application of minimally invasive technique to every stage of SAP can avoid the defects of traditional operations, decrease the injury and interference to the maximum, and raise the cure rate.
Objective To explore an effective micro-traumatechnic with small incision for hallux valgus. Methods From August 2002 to June 2004, 136 cases (263 feet) with hallux valgus were treated with micro-trauma technic with small incision and postoperative external elastic fixation. Of all the cases, 7 were males and 129 werefemales. Their ages ranged from 19 to 84 years. According to Coughlin classification, there were 24 gentle cases, 63 medium cases, and 49 severe cases. All the feet were with some degree of pain and flatfoot. Symptom, sign and theresults of X-ray were evaluated. Results Wound healed at stage Ⅰ.All cases were followed up for 8 to 26 months, 19 months on average. Hallux valgus of the 263 feet were completely healed, feet pain disappeared, and no nonunion or osteonecrosis was observed. Xray examination indicated that 105 feet’s hallux valgus angle was less than 12°, inter metatarsal angle less than 9°, and remedy subluxation of the tibial sesamoid less than 50%. Evaluation on the result indicated that there were 84 cases of excellent result, 48 cases of good result, 3 cases of fair result, and 1 case of poor result. The rate of excellent and good was 97%. Conclusion With less injury, less pain, complete restoration, and fewer possibility of relapse, microtrauma technic with small incision is effective in treating hallux valgus.
Objective To assess the effectiveness of a novel minimally invasive Achilles tendon suture instrument in the treatment of fresh closed Achilles tendon rupture. Methods A retrospective study was conducted on 150 patients who underwent surgical intervention for fresh closed Achilles tendon rupture. Eighty patients were treated with the novel minimally invasive Achilles tendon suture instrument (minimally invasive group) and 70 patients with traditional open surgery (traditional group). The two groups were comparable in terms of gender, age, injured side, cause of injury, the interval between injury and operation, and the distance from the fracture end to the calcaneal tuberosity (P>0.05). The operation time, intraoperative blood loss, incision length, hospital stays, hospitalization expenses, and complications were recorded and compared. At 1 year after operation, the ankle joint function was evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. Results The minimally invasive group demonstrated significantly shorter operation time, smaller incision length, and lower intraoperative blood loss when compared with the traditional group (P<0.05). However, there was no significant difference in terms of hospital stays and hospitalization expenses between the two groups (P>0.05). All patients were followed up 12-24 months after operation (mean, 15.5 months). In the traditional group, 6 cases of incision necrosis and 7 cases of Achilles tendon adhesion occurred, while in the minimally invasive group, all incisions healed at first intention and no Achilles tendon adhesion occurred. The differences in the incidences of the two complications between the two groups were significant (P<0.05). At 1 year after operation, the AOFAS ankle-hindfoot score in the minimally invasive group was superior to that of the traditional group (P<0.05). Conclusion In comparison with traditional open surgery, the use of self-designed novel minimally invasive Achilles tendon suture instrument proves to be an ideal technique for treating fresh closed Achilles tendon ruptures. This approach offers the benefits of smaller incisions, fewer complications, and better postoperative functional recovery, without increasing hospital costs.
Objective To summarize the cl inical appl ication of minimally invasive percutaneous locking compression plate (LCP) internal fixation in the treatment of tibial fractures and to evaluate its cl inical effects. Methods From September 2005 to September 2007, 13 patients with tibial fractures were treated with indirect reduction and minimally invasive percutaneous LCP internal fixation, 8 males and 5 females, aged 18-35 years old (27 on average). Among them, the fractures were caused by traffic accidents in 3 cases, by fall ing in 5 cases, by fall ing from height in 4 cases and by bruise in 1 case. The fractures were located at 1/3 upper tibia in 2 cases, at 1/3 medium tibia in 6 cases and at 1/3 lower tibia in 5 cases. All fracture were closed ones. According to the AO classification, 4 cases were type A, 7 type B and 2 type C. The time between fractures and operation was from 3 hours to 5 days (2.5 days on average). Results All incisions obtained heal ing by first intention. All patients were followed up for 10-18 months (13 months on average). All fractures reached cl inical heal ing, and the heal ing time was 12-20 weeks (16 weeks on average). There was no delayed fracture heal ing, nonunion, infection and internal fixation failure. No compl ications such as rotation, crispatura deformity and internal fixation loosening were found. According to the HSS scoring, the function of the knee joint was graded 85-95 (90 on average), and the range of motion was 100-130° (120° on average). According to the AOFAS Ankie Hindfoot Scoring, the function of the ankle joint was graded 80-95 (92.4 on average). Nine cases were excellent, 4 good, and the choiceness rate was 100%. Conclusion Minimally invasive percutaneous LCP internal fixation is in accord with biological set principles and beneficial for tibial fracture heal ing and reconstruction of soft tissues.
Objective To review the application progress of minimally invasive technique in the treatment of calcaneus fractures and to analyze the advantages and disadvantages of each method as well as to predict the trend of development in the field. Methods Domestic and abroad literature concerning the minimally invasive technique applied in calcaneus fractures in recent years was reviewed extensively and analyzed thoroughly. Results There are both advantages and limitations of each minimally invasive technique including percutaneous reduction and fixation, limited incision, external fixator, arthroscopic assisted reduction, and balloon expansion reduction. But every technique is developing rapidly and becoming more and more effective. Conclusion A variety of minimally invasive technique can not only be used independently but also can be applied jointly to complement one another. It needs further study how to improve the effectiveness and expand the indications. And the theoretical basis of evidence-based medicine needs to be provided more.
