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.
【Abstract】ObjectiveTo study the mechanism of spontaneous rupture of hepatocellular carcinoma (HCC). MethodsArticles have been reviewed to find out the theory of spontaneous rupture of HCC. ResultsResearchful results suggested that the injury of small arteries was usually followed in patients of spontaneous rupture of HCC. In this review, the immune complex, which composed of hepatitis B virus e antigen, complement C1q and immunoglobulins, was found deposited in the elastic membrane of arteries. Likely as a result of immune complex deposition, vascular injury occurs mainly in the small arteries where the deposition of immune complex was present. The small arteries in which immune complex deposited are readily injuried and cause hemorrhage and rupture of HCC during vascular load increase. ConclusionWe would conclude that immune complex deposition in vessel wall led to the small arteries injury may be the factor involved in the pathogenesis of spontaneous ruptured HCC.
Objective To study the relationship of hepatitis B virus （HBV） to spontaneous rupture of hepatocellular carcinoma （HCC-SR） and its mechanism. Method The related literatures about theory of HCC-SR were consulted and reviewed. Results The injury of small arteries was usually followed in patients with HCC-SR， which was related to vascular autoimmune injury caused by the HBV infection. The small arteries in which immune complex deposited were readily injured， as a result HCC-SR happened while vascular load increased. Conclusion The HBV infection resulted in vascular autoimmune injury maybe a important factor in the pathogenesis of HCC-SR.
ObjectiveTo investigate the effectiveness of modified suture technique in the treatment of acute closed Achilles tendon rupture.MethodsBetween December 2013 and December 2016, 29 cases with acute closed Achilles tendon rupture were treated with modified suture technique. There were 23 males and 6 females with an average age of 34 years (range, 22-45 years). All patients were sport injuries. The injury located at left side in 22 cases and right side in 7 cases. American Foot and Ankle Surgery Association (AOFAS) ankle and hind foot function score was 44.6±3.6. According to the Amer-Lindholm criteria, 29 cases were rated as poor. MRI showed the complete rupture of the Achilles tendon.ResultsThe operation time was 35-62 minutes (mean, 46 minutes). The intraoperative blood loss volume was 7-15 mL (mean, 10 mL). The incisions healed by first intention, and no sural nerve injury occured. All patients were followed up 5-38 months (mean, 18.4 months). AOFAS ankle and hind foot function score was 93.1±4.3 at 3 months after operation, showing significant difference when compared with the preoperative value (t=–49.581, P=0.000). According to the Amer-Lindholm criteria, the results were excellent in 24 cases and good in 5 cases, and the excellent and good rate was 100%; there was significant difference between pre- and post-operation (Z=–7.294, P=0.000). MRI showed the continuous and integrity of Achilles tendon. No Achilles tendon rupture recurred during the follow-up period.ConclusionModified suture technique in the treatment of acute closed Achilles tendon rupture owns the advantages of less trauma, lower recurrence rate of rupture, lower risk of the sural nerve injury, and satisfactory function recovery.
ObjectiveTo summarize the application and experience of repairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor. MethodsBetween January 2011 and December 2013, 31 patients with spontaneous Achilles tendon rupture were treated by part-Kessler technique with suture anchor. Of 31 cases, 23 were male and 8 were female, aged 16-53 years (mean, 38 years). The left side was involved in 15 cases and the right side in 16 cases. The causes of injury included sudden heel pain and walking weakness during sports in 22 cases; no surefooted down-stairs, slip, and carrying heavy loads in 9 cases. The distance from broken site to the calcaneus adhension of Achilles tendon was 3-6 cm (mean, 4.2 cm). The time from injury to operation was 7 hours to 4 days (mean, 36.8 hours). ResultsAll incisions healed by first intention without nerve injury or adhering with skin. The patients were followed up 6-24 months (mean, 15 months). All patients could complete 25 times heel raising without difficulty at 6 months after operation. No Achilles tendon rupture occurred again during follow-up. At 6 months after operation, the range of motion of the ankle joint in dorsiflexion and plantar flexion showed no significant difference between normal and affected sides (t=0.648, P=0.525; t=0.524, P=0.605). The circumference of the affected leg was significantly smaller than that of normal leg at 6 months after operation (t=2.074, P=0.041), but no significant difference was found between affected and normal sides at 12 months after operation (t=0.905, P=0.426). The American Orthopedic Foot and Ankle Society (AOFAS) scores at 6, 12, 18, and 24 months after operation were significantly higher than preoperative score (P<0.05); the score at 6 months after operation was significantly lower than that at other time points (P<0.05), but no significant difference was shown between the other time points (P>0.05). ConclusionRepairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor can supply strong strain and decrease the shear forces of suture. So part-Kessler technique with suture anchor is successful in repairing spontaneous Achilles tendon rupture.
Objective To compare the difference of the changes of platelet counts after splenectomy between the patients with splenic rupture and patients with cirrhosis and portal hypertension, and to analyze the possible reasons and clinical significance. Methods The platelet count of 47 splenic rupture patients and 36 cirrhosis patients who had been carried out splenectomy from July 2008 to December 2009 in our hospital were counted, and the differences in platelet count and it’s change tendency of two groups were compared. Results In the splenic rupture group，the platelet count of all 47 patients increased abnormally after operation, the maxlmum value of platelet count among 300×109/L-600×109/L in 6 cases，600×109/L-900×109/L in 21 cases，and above 900×109/L in 20 cases. In the cirrhosis group，the maxlmum value of platelet count after operation was above 300×109/L in 26 cases，100×109/L-300×109/L in 8 cases，and below 100×109/L in 2 cases. The difference of maxlmum value of platelet count in the two groups had statistic significance（P=0.00）. Compared with the cirrhosis group, the platelet count increased more significant and decreased more slow in splenic rupture group（P＜0.05）.The abnormal days and rising range of platelet count were higher in patient with Child A than Child B and C（P=0.006，P=0.002）. Conclusions The change of platelet count after operation in splenic rupture group was obviously different from cirrhosis group because of the difference of the liver function and body situation of patients. To patients with splenic rupture or cirrhosis, appropriate treatment based on the platelet count and liver function could obtain good therapeutic effect.
Objective To investigate effectiveness of a improved technique for perforation of patella combined with suture anchor and non-tourniquet for repairing acute rupture of the bone tendon junction of quadriceps tendon. Methods Between June 2010 and June 2016, 15 patients with acute rupture of the bone tendon junction of quadriceps tendon were treated with the improved technique for perforation of patella combined with suture anchor and non-tourniquet. Of them, 14 were male and 1 was female, aged from 19 to 74 years (mean, 44 years). Seven cases were sports injuries, 5 cases were caused by slipping, and 3 cases were caused by violent trauma. The duration of quadriceps tendon rupture ranged from 3 hours to 3 days (median, 2 days). The right side was involved in 9 cases, and the left side in 6 cases. All of the cases were closed injuries. The patients had no sequelae of limb dysfunction and no limb joint surgery in the past. All the patients received anteroposterior and lateral X-ray films of the knee joint and patella axial films during follow-up. Knee function of the patients after operation was evaluated by Lysholm scoring system and Kujala scoring system. Results The operation time was 50-60 minutes (mean, 55 minutes). The intraoperative blood loss was 50-150 mL, with an average of 87 mL. Primary healing of incision was obtained in all patients without complications. All patients were followed up 12-24 months (mean, 18 months). At 1 year after operation, the knee joint function of all patients recovered well; the knee Lysholm score was 92-96, with an average of 94 and the patellofemoral joint Kujala score was 90-95, with an average of 93. There was no re-rupture of quadriceps tendon or loosening of internal fixation during follow-up. According to the lateral and axial X-ray films at 1 year after operation, the patella depth index, femur trochlea depth, sulcus angle, and Insall-Salvati index were 3.62-4.09 (mean, 3.84), 4.45-6.50 (mean, 5.56), 137-145° (mean, 142°), and 0.90-1.18 (mean, 1.06). The lateral patellofemoral angle increased, and the patellar tilt angle and the patella lateral shift distance reduced, all showing significant differences when compared with preoperative ones (P<0.05). Conclusion The improved technique for perforation of patella combined with suture anchor and non-tourniquet for repairing acute rupture of the bone tendon junction of quadriceps tendon can reconstruct a stable patellofemoral joint, increase the strength of fixing, disperse stress effectively and evenly, and increase the area for tendon-bone healing.
From 1982 to 1991, there were 13 cases of traumatic rupture of spleen, 26 percent in a total of 50 cases of splenic rupturesin the same period. The abdominal punctures were all positive preoperatively. In general, traumatic rupture of spleen should bc first repaired, if it failed, the subsplenectomy or transplatation of autosplenic tissues in the omental sack might be adopted. We used the technique to repair the ruptured splenic tissues in order to achieve cure. They did not require a second operation. Immunoiogical evaluation was normal 3-4 week safter operation .No postoperative sepsis was encountered.The follow-up results were good (1-7years,mean 3.5years).
Objective To probe into the surgical methods and therapeutic effect of repairing old calcaneal tendon rupture and defects with tissue engineered tendons. Methods The tissue engineered tendons were prefabricated by co-cultivatingallogeneic tendon cells with composite of carbon fiber and polyglycolic acid for 5 days. From August 1999 to June 2002, 7 patients with calcaneal tendon rupture and defects (5-7 cm in length) were treated with tissue engineered tendons. The defects were repaired by suturing repeatedly with tissue engineered tendons. Meanwhile, the defects were covered by gastrocnemius fascial flap for protection and strengthening. After surgery, the ankle joints were fixed with plaster 4to 6 weeks, and then the functional exercise was done. Results All the patients were followed up 22 to 56 months (46.9 months on average). Six patients achieved healing by the first intention, only one patient had delayed union. No local or systemic complication occurred in all the cases. No patients were given the second operation for adhesion. In accordance with YIN Qingshui’s criterion for therapeutic effect,the results were excellent in 5 cases, good in 1 case and moderate in 1 case. Conclusion Repairing old rupture and defects of calcaneal tendon withtissue engineered tendons can achieve good clinical outcome, it is an optional therapy.
Objective To review the progress in the treatment of acute Achilles tendon rupture. Methods Recent literature about the treatment of acute Achilles tendon rupture was reviewed and analyzed. Results Treatments of acute Achilles tendon rupture include operative and non-operative treatments. Operative treatments include open surgery and percutaneous minimally invasive surgery. Compared with non-operative treatment, operative treatment can effectively reduce the re-rupture incidence, but it had higher complication incidences of wound infection and nerve injury. Although early functional rehabilitation during non-operative treatment could reduce the re-rupture incidence, there is no consistent orthopaedic device and guideline for functional rehabilitation. Conclusion Both operative and non-operative treatments have advantages and disadvantages for the treatment of acute Achilles tendon rupture. No consistent conclusion is arrived regarding functional recovery. Future studies should explore the strategy of early functional rehabilitation during non-operative treatment and its mechanism of promoting tendon healing.
