ObjectiveTo investigate the effectiveness of internal fixation using Kirschner with hole and tension band system with wire winding and pressure in the treatment of patellar fracture. MethodsBetween February 2008 and January 2010, 39 patients with patellar fracture were treated using Kirschner with hole and tension band system with wire winding and pressure. The average age was 37 years (range, 18-65 years), including 23 males and 16 females. The left side was involved in 21 cases and the right side in 18 cases. The causes were falling injury in 21 cases, traffic accident injury in 11 cases, and striking injury in 7 cases. The injury to operation time was 5 hours to 6 days (mean, 3.5 days). Twelve cases had open fractures, and 19 cases had comminuted fractures. ResultsAll incisions healed by first intention, and no deep venous thrombosis of lower limbs formed. Thirty-nine patients followed up 12-21 months (mean, 14 months). There was no wire breaking during operation and after operation. X-ray film showed no re-fracture, fracture displacement, or needle displacement; fracture healed well, fracture line disappeared at 6-8 weeks (mean, 7.5 weeks) after operation. After 12 months, the internal fixation was removed; according to the Lysholm knee score standard, the results were excellent in 22 cases, good in 16 cases, fair in 1 case, and the excellent and good rate was 97.4%. ConclusionInternal fixation using Kirschner with hole and tension band system with wire winding and pressure has satisfactory effectiveness for the treatment of patellar fracture, with the following advantages: wire is not easy to break, the needle does not fall off, and the pressure strength is powerful.
Objective To summarize the cl inical appl ication and experience of repairing acute avulsion-type achilles tendon rupture by locking-loop stereoscopic suture. Methods Between January 2006 and June 2010, 41 cases of acute avulsion-type achilles tendon rupture were treated by locking-loop stereoscopic suture. Among 41 patients, 33 were male and 8were female with an average age of 41 years (range, 18-56 years); the locations were left side in 27 cases and right side in 14 cases. There was palpable defect in 33 cases, 7 cases underwent B-ultrasound, and 1 case underwent MRI to confirm the diagnosis. The time from injury to operation was 36 hours to 7 days. All cases were restored by locking-loop stereoscopic suture. Results All incisions healed by first intention. Thirty-one cases were followed up 12 months to 3 years and 10 months with an average of 17 months. The muscle strength reached grade 5; the patients could walk normally, and the heel raising was powerful at 1 year after operation. The circumference difference between wrong leg and good leg was less than 3 cm, and the ankle dorsiflexion was 20-30°, plantar flexion was 40-50°. No re-rupture of achilles tendon or deep infection occurred during follow-up period. At last follow-up, according to evaluation of curative effects by Arner-Lindholm standard, the results were excellent in 21 cases and good in 10 cases with an excellent and good rate of 100%. Conclusion Locking-loop stereoscopic suturing is a safe and effective method with avulsion-type control abil ity, tensile strength, l ittle effect on the blood supply of the achilles tendon for repairing acute avulsion-type achilles tendon rupture.
Objective To investigate the method and curative effect of malposed-suture hanging and fastening method of double-lariat lock catch knot in repairing origin of medial collateral l igament (MCL) rupture. Methods From February 2008 to February 2009, 36 patients with acute MCL rupture were treated with malposed-suture hanging and fastening method of double-lariat lock catch knot. There were 21 males and 15 females with an average age of 40 years (range, 17-58 years),including 19 left knees and 17 right knees. Repture was caused by traffic accident in 5 cases, by fall ing in 11 cases, by kicking in 3 cases, by crush in 4 cases, and by sprain in 13 cases. The X-ray films of double knees at stress state showed the medial joint space of affected knee joint increased 6.5-13.5 mm (11.2 mm on average) when compared with that of normal knee joint. The time from injury to operation was 36 hours to 8 days (3.5 days on average). Results All wounds healed by first intention. Thirty-one cases were followed up 12-20 months (15 months on average). No compl ication of wound infection, deep venous thrombosis, and l igament rerupture occurred. The medial joint space of affected knee joint increased 1.5-5.6 mm (3.5 mm on average) when compared with that of normal knee joint. According to Lysholm assessment standard, the results were excellent in 20 cases and good in 11 cases, the excellent and good rate was 100%. Conclusion Repair of origin of MCL with malposedsuture hanging and fastening method of double-lariat lock catch knot has advantages of less injury, rel iable fixation, and rapid recovery of knee stabil ity.
