ObjectiveTo investigate the medium-term effectiveness of both side stereo suture for meniscus bucket handle tear under arthroscopy. MethodsBetween January 2009 and December 2012, 38 patients with combined injury of meniscus bucket handle tear underwent arthroscope surgery by the method of both side stereo suture. There were 26 males and 12 females with an average age of 32 years (range, 19-42 years). The injury causes included sports injury in 21 cases, traffic accident injury in 11 cases, and other trauma in 6 cases. The left knee was involved in 15 cases and the right knee in 23 cases. The interval between injury and operation was 2 days to 6 months (mean, 2.5 months). MRI examination showed meniscus injury at grade Ⅲ, including 22 cases of internal injury and 16 cases of lateral injury. The Barrett standard, Lysholm score of knee joint, and joint mobility were used to assess the function recovery of the knee joint. ResultsAll incisions healed primarily with no complication. All cases were followed up 24.5 months on average (range, 18-36 months). Based on the Barrett standard, meniscus bucket handle tear was successfully repaired in all cases. The Lysholm scores and range of motion of the knee at 6 months, 12 months, and last follow-up were significantly better than preoperative ones (P<0.05). ConclusionThe both side stereo suture of meniscus bucket handle tear under arthroscopy has an excellent medium-term effectiveness, with the advantages of firm suture and high healing rate.
Objective To evaluate the effect of mechanical suture in surgery of esophageal carcinoma,Methods Five hundred and sixty-eight cases of esophagogastrostomy and esophagojejunostomy for esophageal and cardiac carcinoma were collected in our hospital between January, 1988 and December, 2002. They were devided into two groups according to the methods of anastomoses, the group by stapler and the group with hand. The incidence of postoperative complications in the two groups was compared. Results The time of esophagogastrostomy, the total operating time, and postoperative fasting time of group by stapler were shorter than those of group with hand （Plt;0. 01）, and there was no statistically difference in the median hospitalized time after operation for two groups. The anastomotic leakage, anastomotic stricture, anastomotic bleeding , incidence of postoperative complications in respiration and circulation and mortality rate of group by stapler were lowed than those of group with hand （2.1%, 1.4%,0%,2.8% and 0.7% vs.6.8%,4.3%,1.4%,16.5% and 2.9%）. There was no statistical difference in the postoperative gastro-esophageal reflux for two groups （P 〉 0.05 ）. Conclusion The median time of esophagogastrostomy and the median operating time by stapler are decreased and the incidence of postoperative complications is decreased.
Objective To investigate the effectiveness of double-needle suture for mixed meniscus tear repair under arthroscope. Methods Between April 2006 and January 2011, 22 patients with mixed meniscus tear were treated with double-needle suture under arthroscope. There were 14 males and 8 females, aged 18-41 years (mean, 31.3 years). All injuries were caused by sports. The time between injury and admission ranged from 2 days to 4 years (median, 11 months). International Knee Documentation Committee (IKDC) score was 42.5 ± 15.2, Lysholm score was 45.5 ± 13.5, and Tegner score was 2.9 ± 1.6. Seventeen cases complicated with anterior cruciate ligament injury. Results Healing of incision by first intention was achieved in all patients. No injury of nerve and blood occurred. The patients were followed up 12-48 months with an average of 27.6 months. According to Barrett et al. standard, 19 cases (86%) got clinical healing. The IKDC, Lysholm, and Tegner scores were improved to 77.1 ± 8.9, 79.8 ± 9.9, and 6.8 ± 1.6 respectively at last follow-up, showing significant differences when compared with preoperative scores (P lt; 0.05). Conclusion Arthroscopic meniscus repair using double-needle suture can provide good effectiveness because it has high firmness.
Objective To evaluate the surgical techniques and effectiveness of arthroscopic treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fracture with non-absorbable suture fixation combined with the mini-plate. Methods Between January 2009 and March 2012, 32 patients with ACL tibial eminence avulsion fractures were treated. There were 18 males and 14 females, aged 12-40 years (mean, 17.5 years). The injury causes included traffic accident injury in 15 cases, sport injury in 6 cases, and falling injury in 11 cases. The time from injury to operation ranged 7-18 days with an average of 9.5 days. Before operation, the results of Lachman test were all positive; the Lysholm score was 52.13 ± 4.22 and the International Knee Documentation Committee (IKDC) score was 44.82 ± 2.44. According to Meyers-McKeever classification criteria, there were 12 cases of type II and 20 cases of type III. After arthroscopic poking reduction of fracture, tibial eminence avulsion fractures were fixed with the Ethibond non-absorbable sutures bypass figure-of-eight tibial tunnel combined with the metacarpal and phalangeal mini-plate. Results Primary healing was obtained in all incisions; no joint infection or skin necrosis occurred after operation. All patients were followed up with an average time of 22.4 months (range, 12-50 months). The patients showed negative Lachman test at 12 weeks after operation. Except 3 patients having knee extension limitation at last follow-up, the knee extension range of motion (ROM) was normal in the other patients; the knee flexion ROM was normal in all patients. The Lysholm score and IKDC score were significantly improved to 94.19 ± 0.93 and 94.35 ± 1.22 at last follow-up, showing significant differences when compared with preoperative values (t=55.080, P=0.000; t=101.715, P=0.000). Conclusion The arthroscopic treatment of ACL tibial eminence avulsion fracture with Ethibond non-absorbable suture fixation combined with mini-plate is an effective procedure with the advantages of minimal trauma, reliable fixation, and satisfactory recovery of the knee joint function.
Objective To investigate the impact of joint capsule repair and external rotators suture on the prognosis in primary total hip arthroplasty (THA) by posterolateral approach. Methods Between January 2006 and June 2009, 159 patients with femoral neck fracture underwent primary THA by posterolateral approach, and were divided into 4 groups according to different treatments: joint capsule repair and external rotators suture were given in group A (n=38), only joint capsule repair in group B (n=39), only external rotators suture in group C (n=41), and no joint capsule repair or external rotators suture in group D (n=41). There was no significant difference in gender, age, cause of injure, disease duration, type of fracture, combined medical disease, or prosthesis selection among 4 groups (P gt; 0.05). The bleeding volume, drainage, postoperative hip dislocation rate, hip Harris score, and the hip range of motion (ROM) in internal rotation and external rotation were compared. Results There was no significant difference in operative time, bleeding volume, or drainage among 4 groups (P gt; 0.05). Postoperative hip dislocation occurred in 0, 0, 4 (9.8%), and 4 (9.8%) cases of groups A, B, C, and D, respectively, showing significant difference in incidence of postoperative hip dislocation among 4 groups (χ2=7.910, P=0.048). The hip Harris scores were significantly improved after operation when compared with preoperative scores in 4 groups (P lt; 0.05). Significant differences were found in hip Harris score at 6 weeks and 6 months after operation among 4 groups (P lt; 0.05); group D was significantly lower than groups A, B, and C, and groups B and C were significantly lower than group A (P lt; 0.05). There was no significant difference in the hip ROM in internal rotation among 4 groups at 6 weeks and 6, 12 months after operation (P gt; 0.05); but the hip ROM in external rotation were significantly bigger in groups A and C than in groups B and D at 6 weeks and 6 months after operation (P lt; 0.05). Conclusion Joint capsule repair and external rotators suture in primary THA by posterolateral approach do not increase the bleeding volume and drainage, but can reduce the early postoperative hip dislocation risk, increase the Harris score, and recover the external rotation function of involved hip. So joint capsule and external rotators should be repaired in THA by posterolateral approach.
Objective To evaluate the surgical technique and effectiveness of arthroscopic treatment for lateral discoid meniscus injury. Methods Between January 2010 and May 2011, 38 patients (42 knees) with lateral discoid meniscus injuries underwent arthroscopic treatment. There were 23 males (24 knees) and 15 females (18 knees), aged 7-62 years (median, 32.8 years). The disease duration was 7 days to 40 years (median, 8.6 months). According to Watanabe’s classification of discoid meniscus, 22 knees were classified as complete type, 19 knees as incomplete type, and 1 knee as Wrisberg type. Meniscus plasty combined with suture was performed in 25 patients (28 knees), partial meniscectomy in 12 patients (13 knees), and complete meniscectomy in 1 patient (1 knee). After operation, the rehabilitation training programs (including straight-leg-raising exercise and range of motion exercise) were carried out. Results All incisions healed primarily. The patients basically had normal activities after 3-4 weeks. All the patient were followed up 12-18 months (mean, 14.3 months). No joint locked or clicking symptom occurred; no tear or revision was noted during follow-up. At 3 months, 6 months, and 1 year after operation, the range of flexion and extension were significantly improved when compared with ones at preoperation (P lt; 0.05). Based on Ikeuchi’s grading, the results were excellent in 22 knees, good in 16 knees, and fair in 4 knees with an excellent and good rate of 90.4%. The Lysholm score was significantly increased to 88.57 ± 2.95 at immediate, 91.02 ± 4.17 at 3 months, 92.90 ± 3.36 at 6 months, and 94.74 ± 3.52 at 12 months after operation from 69.38 ± 4.59 before operation (P lt; 0.05). C onclusion Treatment of lateral discoid meniscus injury under arthroscopy has the advantages of minor trauma, precise resection or repair meniscus, preservation of more meniscus function, and low incidence of osteoarthritis. If the operation is combined with standard rehabilitation training, the short-term effectiveness can be enhanced.
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 compare the advantages and disadvantages between double Perclose ProGlide crossing suture and traditional suture for the closure of 20F or 22F access points so as to provide a basis for selecting appropriate approach to repair the puncture points in endovascular aortic repair. Methods Between June 2007 and May 2011, 103 patients (115 common femoral arteries) underwent endovascular aortic repair using sheaths of 20F or 22F (outer diameter); double Perclose ProGlide crossing suture was performed for closure of puncture sites in 57 cases (64 common femoral arteries) (double Perclose group) and traditional suture in 46 cases (51 common femoral arteries) (traditional group). There was no significant difference in age, gender, or disease duration between 2 groups (P gt; 0.05). Results The operation time, blood loss, and hospitalization days of double Perclose group were significantly better than those of traditional group (P lt; 0.05). Ecchymoma in inguinal region and lymphatic leakage occurred in 5 cases (5 common femoral arteries) and 2 cases (2 common femoral arteries) of double Perclose group respectively, in 2 cases (2 common femoral arteries) and 6 cases (8 common femoral arteries) of traditional group respectively; no significant difference was found in the rate of the early complication between double Perclose group and traditional group (7.8% vs. 15.7%, χ2=1.76, P=0.19). The technique success rate of double Perclose group was 96.9% (62/64), and was 100% (51/51) in traditional group, showing no significant difference (χ2=0.31, P=0.50). All patients were followed up, 2-19 months (mean, 15 months) in double Perclose group and 2-18 months (mean, 14 months) in traditional group. Pseudoaneurysm occurred in the puncture region at 3 months in 1 case (1 common femoral artery) of double Perclose group, and incision and suture therapy was performed; no arteriostenosis or pseudoaneurysm occurred in other cases; and the rate of mid-term complication was 1.6% (1/64) in double Perclose group and was 0 in traditional group, showing no significant difference (P=1.000). Conclusion Double Perclose ProGlide crossing suture has the same effectiveness to traditional surture in repairing the puncture point with 20F or 22F, but it is superior to traditional suture in reducing operation time, blood loss, and hospitalization days.
ObjectiveTo compare the effectiveness between micro-anchor repair and modified pull-out suture in the treatment of mallet fingers. MethodsBetween June 2010 and March 2011, 33 patients with mallet fingers were treated by micro-anchor repair method (n=18, group A) and by modified pull-out suture method in which the broken tendons were sutured with double metal needle Bunnell’s suture and a knot was tied palmarly (n=15, group B). There was no significant difference in age, gender, and disease duration between 2 groups (P gt; 0.05). ResultsThe operation time was (62.5 ± 3.1) minutes in group A and (65.0 ± 4.6) minutes in group B, showing no significant difference (t=1.85, P=0.07). The treatment expense in group A [(8 566.2 ± 135.0) yuan] was significantly higher than that in group B [(5 297.0 ± 183.5) yuan] (t=58.92, P=0.00). Incision infection occurred in 2 cases of group A and 1 case of group B; the other patients obtained healing of incision by first intention. Relapsed mallet finger was observed in 1 case of group B. All patients in 2 groups were followed up 12-21 months. According to the Crawford functional assessment system, the results were excellent in 5 cases, good in 10 cases, fair in 2 cases, and poor in 1 case at the last follow-up with an excellent and good rate of 83.3% in group A; the results were excellent in 4 cases, good in 9 cases, fair in 1 case, and poor in 1 case with an excellent and good rate of 86.7% in group B. There was no significant difference in the excellent and good rate between 2 groups (χ2=0.23, P=0.97). ConclusionBoth micro-anchor repair and modified pull-out suture are simple and effective methods in the treatment of mallet finger. But compared with micro-anchor repair, pull-out suture has lower expense.
