Objective To investigate the cl inical effect of minimally invasive internal fixation percutaneous plate osteosynthesis (MIPPO) assisted by arthroscopy on tibial plateau fractures. Methods From September 2005 to December 2007, 29 patients with tibial plateau fracture underwent arthroscopy-assisted MIPPO, including 18 males and 11 females aged18-59 years old (average 34.7 years old). There were 8 cases of type II, 10 of type III, 5 of type IV, 3 of type V, and 3 of type VI according to Schatzker classification system. The fracture was combined with meniscus injury in 13 cases, anterior cruciate l igament injury in 4 cases, and medial collateral l igament injury in 3 cases. The time from injury to operation was 2-10 days. Firstly, the combined injury was treated under arthroscopy. Then, reduction of tibial plateau fractures was performed, bone grafting was conducted in the area of bone defect, and internal fixation using strut plates was performed after establ ishing subcutaneous tunnel via minimally invasion. Early rehabil itation activities were carried out for each patient 1 day after operation. Results No early compl ications such as poor heal ing of incisions, infections, and osteofascial compartment syndrome occurred. Over the follow-up period of 12-39 months (average 24 months), there was no failure of internal fixation, traumatic knee osteoarthritis, and inversion and eversion of the knee. The fractures healed within 3-4.5 months (average 3.5 months). The cl inical effect was excellent in 23 cases, good in 4 cases, and fair in 2 cases according to Lysholm knee rating system, and the excellent and good rate was 93.1%. Conclusion Arthroscopy-assisted MIPPO is a safe and effective way of managing tibial plateau fractures due to its features of minimal invasion, earl ier recovery, fewer compl ications, and simultaneous treatment of associated intra-articular injuries.
Objective To evaluate the clinical value of ureteroscope in cholelithiasis treated by laparoscopic surgery. Methods The clinical data of 36 patients admitted because of hepatolithus with ureteroscope combination in laparoscopic surgery from February 2007 to September 2009 in Guidong People’s Hospital of Guangxi were analyzed retrospectively. Results In 33 cases, stones were removed once by ureteroscope in laparoscopic surgery with residual stones (in 3 cases residual stone were removed secondarily through T tube) and the other 3 cases were transferred to laparotomy forcedly due to bleeding of biliary duct and vessels of porta hepatis and tearing of bile duct. During operation, blood loss was 30-280 (94.51±54.70) ml; operation time was 110-260 (147.22±48.45) min; recovery time of bowel movement was 1-3 (2.03±0.76) d; postoperative hospitalization time was 6-13 (7.12±1.65) d (some discharged with T tube); the time of patients of T tubes pulled out was 28-45 (38.92±6.52) d. Bile leakage happened in 1 case and infection of biliary tract in 1 case, no complications such as biliary stricture or bile duct bleeding were found after operation. Conclusions Treatment of intrahepatic bile duct or a single extra-hepatic sand-like stones with ureteroscopy usage in laparoscopic surgery is feasible and less invasive. It is a minimally invasive treatment for intra- or extra-hepatic stones due to rapidly postoperative rehabilitation.
Objective To expand the utilization of minimally invasive technologies for parapancreatic abscess, and summarize the application experience of choledochoscope for treatment of parapancreatic abscess. Methods The clinical data and treatment effectiveness of 36 patients with parapancreatic abscess from Dec. 2000 to Dec. 2008 were analyzed retrospectively. These patients had experienced percutaneous puncture and been placed drainage tube under the ultrasound guidance first, then expanded the sinus tract gradually, and performed debridement by choledochoscope. The flexibility of choledochoscope was used to remove the necrotic tissue and pyogenic membrane repeatedly by clamping, netting and vacuum aspiration in every domain. Results Thirty-six patients were performed percutaneous puncture and placed drainage tube, 3 cases were given canalis singularis, 7 cases were double tube, 26 cases were over three tube. The debridement times were 3-14 by choledochoscope, average 5.6 times. There were 6 cases with improving systemic symptoms, blood routine and temperature recovering normal, and drink and food recovering, then discharged from hospital with tube after 1-2 times of debridement. Length of stay was 25-132 d, average 76 d. The curing rate was 91.7% (33/36). Two cases were turned into open surgery because of broad necrotic tissue range combined with many abdominal cavity abscess with good postoperative recovery and cured. One case was dead of severe multiple organ failure combination. There were 2 patients with hemorrhage, 3 patients with external intestinal fistula. Conclusions The debridement of choledochoscope for parapancreatic abscess treatment is a simple, flexible and effective method. It changes the viewpoint that parapancreatic abscess can be cured only by operation drainage, decreases the patients’ trauma and accomplishes the idea of damage control by minimally invasive technologies.
ObjectiveTo compare the clinical results between percutaneous poking reduction fixation and open reduction and internal fixation for the displaced Sanders Ⅱ type calcaneal fractures. MethodsA retrospective analysis was made on the clinical data of 122 patients with Sanders Ⅱ type calcaneal fractures between May 2007 and May 2012, who accorded with the inclusion criteria. The closed reduction and percutaneus Kirschner wire fixation were used in 61 patients (closed group), and open reduction and internal fixation were used in 61 patients (open group). There was no significant difference in gender, age, fracture side, weight, height, body mass index, the causes of injury, the fracture type, Böhler angle, Gissane angle, and the time from trauma to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, hospitalization days, wound complications, fracture healing time, American Orthopaedic Foot and Ankle Society (AOFAS) score, and radiographic results were compared between 2 groups. ResultsThe operation time, intraoperative blood loss, and hospitalization days in closed group were significantly less than those in open group (P<0.05). There was no deep infections in both group; wound dehiscence, skin flap necrosis, and wound infection occurred in 3 patients, 2 patients, and 1 patient of the open group, no wound complication happened in closed group, and there was significant difference in the incidence of wound complications between 2 groups (P=0.027). The patients were followed up 24-68 months (mean, 38.7 months) in the closed group and 26-66 months (mean, 38.7 months) in the open group. There was no significant difference in the fracture healing time between 2 groups (t=-1.562, P=0.121). The Böhler angle and Gissane angle at last follow-up were significantly improved when compared with preoperative angle in the closed group (t=-27.929, P=0.000; t=-26.351, P=0.000) and the open group (t=-32.565, P=0.000; t=-25.561, P=0.000), but there was no significant difference between 2 groups (P>0.05). AOFAS score showed no significant difference between 2 groups (t=-0.492, P=0.624). ConclusionFor the displaced Sanders Ⅱ type calcaneal fractures, the use of closed reduction and percutaneus Kirschner wire fixation or open reduction and internal fixation can both obtain satisfactory clinical function and radiographic results, but the former has the advantage of less trauma, shorter hospitalization time, and fewer wound complications.
ObjectiveTo evaluate the effectiveness of minimally invasive osteosynthesis using the helical plate for complex humeral shaft fractures involved proximal metaphysis, and to explore its feasibility and security. MethodsA retrospective analysis was made on the clinical data of 16 patients with complex humeral shaft fractures involved proximal metaphysis who underwent minimally invasive osteosynthesis with the helical plate between December 2009 and May 2015. There were 11 males and 5 females, aged from 18 to 56 years (mean, 34.6 years). The causes of fracture included falling injury in 5 cases, falling injury from height in 3 cases, traffic accident injury in 4 cases, sports injury in 3 cases, and belts twisted injury in 1 case. Accroding to Orthopaedic Trauma Association (OTA) classifications, 6 cases were rated as type 12-C1, 3 cases as type 12-C2, and 7 cases as type 12-C3. The time between injury and operation was 2-13 days (mean, 7.2 days). The operation time, intraoperative blood loss, complications, union time were recorded, the functional outcome of the elbow joint was evaluated by Mayo elbow performance score, and the function of the shoulder was assessed by the University of California at Los Angeles (UCLA) shoulder rating scale. ResultsThe mean operation time was 92 minutes (range, 51-127 minutes), and the mean intraoperative blood loss was 212 mL (range, 100-450 mL). All incisions healed by first intention without neurologic complications or wound infection. All patients were followed up 8-28 months (mean, 16.6 months), and bony union was obtained at 13-36 weeks (mean, 19.2 weeks). No loosening or breakage of internal fixation occurred. The Mayo elbow performance score was 90-100 (mean, 99), and the UCLA shoulder rating scale was 31-35 (mean, 34.6). ConclusionThe technique of minimally invasive osteosynthesis using the helical plate is safe and feasible for humeral shaft fracture, especially for complex humeral shaft fractures involved proximal metaphysis, and it has the advantages of minimal invasion and low risk for iatrogenic nerve injury and satisfactory effectiveness.
