Objective To explore the method and outcome of knee resurfacing arthroplasty in treating late-staged diffuse pigmented villonodular synovitis (PVNS). Methods Between November 2002 and May 2009, 11 cases of late-staged diffuse PVNS were treated, including 3 males and 8 females with an average age of 51.2 years (range, 42-63 years). The diseaseduration was 2.5-10.0 years (mean, 5.2 years). Unilateral knee was involved in all patients, including 7 left knees and 4 right knees. Nine patients had a history of trauma and 2 cases had no obvious inducing factors. The range of motion was (90.1 ± 17.2)° and Hospital for Special Surgery Knee Score (HSS) was 68.9 ± 8.7. After synovectomy, knee resurfacing arthroplasty was performed in all patients. Results Superficial infection of the incision occurred in 1 case at 6 days postoperatively and was cured after debridement; other incisions healed by first intention. Limited flexion and extension, incomplete palsy of common peroneal nerve, and deep venous thrombosis occurred in 1 case respectively, and were cured or improved after symptomatic treatment. All the 11 cases were followed up 38 months on median (range, 13 to 102 months). Two cases developed chronic pain and were not given treatment. Recurrence occurred in 1 case 12 months postoperatively and recovered after synovectomy again. X-ray films showed no signs of loosening, sinking, and bone destruction. At last follow-up, the range of motion was (109.1 ± 18.6)° and HSS score was 86.7 ± 9.3, showing significant differences when compared with those before operation (P lt; 0.05). According to the HSS score system, the results were excellent in 6 cases, good in 3, fair in 1, bad in 1, and the excellent and good rate was 81.8%. Conclusion A combination of knee resurfacing arthroplasty and synovectomy for the treatment of late-staged diffuse PVNS is able to get a good cl inical results in restoration of function, improvememt of the l ife quality, and decrease of recurrence rate.
Objective To evaluate the postoperative effects of different thoracoscopic sympathectomy on palmar hyperhidrosis patients. Methods We searched the Wanfang Database, CNKI, Weipu, CBM, PubMed, Cochrane Library (from inception to March 2016) to identify studies about thoracoscopic sympathectomy on palmar hyperhidrosis patients. Quality of the included studies was evaluated. The meta-analysis was performed by RevMan5.3 software. Results A total of 15 studies (9 randomized controlled trials, 3 cohort studies, and 3 retrospective studies) involving 2 542 patients were included. The result of meta-analysis suggested that there was statistical difference in postoperative compensatory hyperhidrosis (OR=4.88, 95% CI 1.88 to 12.68,P=0.001) between T2 sympathectomy and T3 sympathectom. Compared with T2-4 sympathectomy patients, the risk of postoperative compensatory hyperhidrosis in T2-4 sympathectomy group was significantly lower (OR=5.13, 95% CI 2.91 to 9.02,P<0.000 01). Compared with T3 sympathectomy group, the risk of postoperative compensatory hyperhidrosis and hand dry in the T4 sympathectomy group was significantly lower (OR=2.91, 95% CI 2.06 to 4.12,P<0.000 01;OR=14.60, 95% CI 3.06 to 69.63,P=0.000 8), respectively. Conclusion The rate of postoperative compensatory hyperhidrosis or hand dry is lower on T4 sympathectomy patients and supposed to be the best segment for the treatment of palmar hyperhidrosis patients.
Objective To explore the effectiveness of bipolar femoral head replacement combined with tension band wire fixation for intertrochanteric fracture in elderly osteoporotic patients. Methods Bipolar femoral head replacement combined with tension band wire fixation were used for intertrochanteric fracture in 48 elderly osteoporotic patients between January 2004 and December 2010. Of 48 patients, 15 were male and 33 were female, aged 90-99 years (mean, 94.1 years). All fractures were caused by falling, and pathological fracture was excluded. It was 2-7 days (mean, 4.2 days) from fracture to surgery. According to the Tronzo Evans classification, 25 cases were rated as type IV, 20 cases as type III, and 3 cases as type II. And all of the cases were accompanied with severe osteoporosis and accompanied by more than one medical diseases, and 10 cases had spinal compression fracture. Results All patients underwent the operation successfully. Six cases died of underlying medical illness within 2 years postoperatively. A total of 39 cases were followed up 2-7 years, averaged 3.1 years. After operation, short-term mental disorders occurred in 9 cases, suspected urinary tract infection in 2 cases, sacral rear bedsore in 1 case, hip pain in 1 case, thigh pain in 1 case, and deep vein thrombosis of affected limb in 1 case. All the incisions healed by first intension, and X-ray film showed bone union in all cases; no complications of bone osteolysis, prosthesis loosening, subsidence, rupture, and heterotopic ossification occured postoperatively. No case needed revision. According to the Harris score system, the results were excellent in 5 cases, good in 28 cases, fair in 5 cases, and poor in 1 case, with an excellent and good rate of 84.6%; the score at 2 years was significantly higher than that at 6 weeks (t= — 14.79, P=0.00). The physical health score and mental health score of SF-12 at 2 years postoperatively were significantly higher than those at 6 weeks postoperatively (P lt; 0.05). The visual analogue scale (VAS) scores at 6 weeks and 2 years postoperatively were significantly lower than those at preoperation (P lt; 0.05), and the score at 2 years was significantly lower than that at 6 weeks (P lt; 0.05). Conclusion The bipolar femoral head replacement combined with tension band wire fixation for intertrochanteric fracture in elderly osteoporotic patients has the advantages of firm fixation, early function exercise with load bearing, pain relieving, improving hip function, and avoiding complication in bed.
Objective To evaluate the effect of remote ischemic perconditioning on inflammation and oxidative stress in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB). Methods Sixty adult patients undergowent cardiac valve replacement under CPB. There were 29 males and 31 females with an age ranging from 40–60 years and weight from 45–70 kg. They were randomly divided into 2 groups (n=30 in each) by random number generator: a control group (group C, 14 males and 16 females) and a remote ischemic perconditioning group (group R, 15 males and 15 females). Anesthesia was induced with intravenous injection of midazolam, fentanyl, vecuronium. The patients were mechanically ventilated after endotracheal intubation. Anesthesia was maintained with intravenous injection of midazolam, fentanyl, vecuronium and inhalation of sevoflurane. Three cycles of 5-min ischemia and 5-min reperfusion were performed on the right lower extremity immediately after aortic occlusion by means of a tourniquet in group R. A tourniquet was only placed under the right lower extremity in group C. Before CPB and at 0, 1, 6 and 24 h after termination of CPB (T0-4), blood samples were obtained from the right internal jugular vein for determination of levels of serum IL-6, IL-10, SOD and MDA and the count of white blood cell and the percentage of monocytes. The bladder temperature was measured at T0-4 and SIRS score was evaluated on preoperative 1 d and postperative 1, 2 and 3 d. Tracheal extubation time and length of ICU stay were record. Results Compared with group C, the concentration of serum IL-6 at T1-3, the concentration of MDA at T1, the count of leukocyte T3, the bladder temperature at T4 and the SIRS scores on postperative 1 d were significantly decreased, while the concentration of serum IL-10 at T2-T3, the SOD activity at T1-T2, and the percentage of monocyte at T3-T4 were significantly increased in group R (P<0.05). Tracheal extubation time and length of ICU stay in group R were significantly shorter than those of group C (P<0.05). Conclusion Remote ischemic perconditioning can reduce inflammation and oxidative stress and improve post-operative recovery in patients undergoing cardiac valve replacement with CPB.
ObjectiveTo evaluate the effectiveness of femoral oval tunnel technique versus round tunnel technique in single-bundle anterior cruciate ligament (ACL) reconstruction.MethodsBetween March 2016 and February 2018, 125 patients who underwent anatomical single-bundle ACL reconstruction with hamstring tendon and met the inclusive criteria were included in the retrospective study. Of the included patients, 43 patients underwent ACL reconstruction using oval tunnel technique (group A) and 82 patients with round tunnel technique (group B). There was no significant difference between the two groups in terms of age, gender, body mass index, the interval between injury and operation, the injured side, the cause of injury, and preoperative Lysholm score, International Knee Documentation Committee (IKDC) score, Tegner score, and the outcome of KT-1000 measurement (P>0.05). At 3, 6, 12, and 24 months after operation, the knee function scores (Lysholm score, IKDC score, Tegner score) were recorded; and KT-1000 was used to evaluate the knee stability. The position and shape of the tunnels were evaluated by the three-dimensional CT (3D-CT) at 1 day after operation; and MRI was performed at 6, 12, and 24 months to calculate the signal/noise quotient (SNQ) of ACL grafts. Secondary arthroscopy was conducted to estimate the graft status, synovial coverage, and tension.ResultsAll patients were followed up 12-26 months (mean, 23 months). Two patients in group A and 5 patients in group B presented with redness and swelling of the surgical site, 1 patient in group B sustained a tibial tunnel fracture, and 1 patient in group A had postoperative stiffness. The Lysholm score, IKDC score, and Tegner score were significantly higher in group A than in group B at the different time points (P<0.05) except for the Tegner score at 3 months. The outcomes of KT-1000 measurement were significantly lower in group A than in group B (P<0.05). The entrances of the femoral tunnel and tibial tunnel in both groups were within the ACL anatomical footprint confirmed by 3D-CT. No re-rupture of ACL occurred confirmed by the MRI. There was no significant difference in SNQs of the middle and distal grafts between the two groups at 6 months (P>0.05), whereas the SNQ of the proximal grafts in group A was significantly lower than that in group B (P<0.05). The SNQs of the proximal, middle, and distal grafts in group A were significantly lower than those in group B at 12 and 24 months after operation (P<0.05). Twenty-one patients in group A and 38 patients in group B underwent secondary arthroscopy and the results showed no significant difference in graft status, synovial coverage, and tension between the two groups (P>0.05).ConclusionThe effectiveness and graft maturity of the femoral oval tunnel technique were superior to the round tunnel technique. The single-bundle ACL reconstruction with femoral oval tunnel technique can obtain a better knee function.
