Objective To assess the effect of atraumatic restorative treatment (ART) on decayed deciduous and permanent teeth in children. Methods Such databases as CENTRAL of The Cochrane Library, MEDLINE, EMbase, CBM, CNKI, and VIP were searched, and the China clinical trial register center were also searched. The search was conducted by the end of April, 2009 to collect the randomized controlled trials (RCTs) of ART vs. conventional restorative treatment (CRT) for childhood caries. The data extraction was performed by two reviewers independently. The quality of the included studies was critically assessed and the data analyses were performed by the Cochrane Collaboration’s RevMan 5.0.2 software. Results A total of seven randomized controlled trials were included. Only was the descriptive analysis conducted because of the difference of restorative materials used in each study, the types of target teeth, the measure indexes, and the year limit of follow up, which showed that, most of the included studies suggested that the survival rate of restorative materials in all types of caries hole was similar between the ART group and the CRT group; only a few studies suggested that the CRT group was superior to the ART group; the children in the ART group felt more comfortable than those in the CRT group during the treatment procedure; two studies compared the working time and got an opposite results. Conclusion Because of the higher clinical heterogeneity of the include studies, the merger analysis fails to be conducted, so it is impossible to get a precise conclusion about the effect of treating childhood caries with ART vs. CRT, and more RCTs with high quality are needed for confirmation.
Objective To evaluate the effectiveness of arthroscopic debridement and release for post-traumatic arthritis of subtalar joint. Methods Between January 2011 and December 2014, 14 cases of post-traumatic arthritis of the subtalar joint underwent arthroscopic debridement and release, and the clinical data were retrospectively analyzed. All patients were male, aged 42 years on average (range, 32-62 years). Calcaneus fracture was caused by falling from height; 8 cases received conservative treatment and the other 6 cases received open reduction and internal fixation. The mean interval from injury to operation was 3.4 years (range, 2-7 years). The arthroscopic debridement and release were performed through lateral portals. The injury degree of articular cartilage was classified as grade 3 in 4 cases and grade 4 in 10 cases based on Outerbridge rating. The degree of pain was assessed by visual analogue scale (VAS) and the function of joint was assessed by the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle Hindfoot Scale. Results All incisions healed by first intention and no complication occurred. The follow-up time was 18 months. Pain was relieved obviously; VAS was significantly decreased to postoperative 3.8±0.9 at 18 months from preoperative 7.7±1.2 (t=9.728,P=0.000), and AOFAS Ankle Hindfoot Scale was significantly increased to postoperative 59.1±8.8 from preoperative 37.6±8.2 (t=6.688,P=0.000). During follow-up, no patient was given arthrodesis and no worsened sign was found on the postoperative CT and MRI. Conclusion Arthroscopic debridement and release for post-traumatic arthritis of the subtalar joint can relieve clinical symptoms and delay subtalar arthrodesis.
ObjectiveTo explore the effectiveness of vacuum sealing drainage (VSD) combined with open bone graft for tibial traumatic osteomyelitis. MethodsBetween June 2007 and December 2012, 23 cases of tibial traumatic osteomyelitis were treated, including 15 males and 8 females with an average age of 32.5 years (range, 22-48 years). The time from injury to admission was 7-18 months (mean, 8.6 months). There was local bone scarring in 15 cases, the size ranged from 8 cm×4 cm to 15 cm×8 cm. The CT multi-planar reconstruction was carried out preoperatively. Eleven cases had segmental bone sclerosis with a length of 1.5 to 3.8 cm (mean, 2.6 cm); 12 cases had partial bone sclerosis with a range of 1/3 to 2/3 of the bone diameter. On the basis of complete debridement, infection was controlled by VSD; bone defect was repaired by VSD combined with open bone graft. After there was fresh granulation tissue, the wound was repaired by free skin graft or local skin flap transfer. ResultsNail infection occurred in 2 cases, which was cured after the use of antibiotics. The wound healed at the first stage after repairing. All cases were followed up 10-18 months (mean, 13.5 months). In 11 cases of segmental bone sclerosis, the infection control time was 7-14 days (mean, 8.8 days); the bone healing time was 32-40 weeks (mean, 34.4 weeks); and the frequency of VSD was 3-6 times (mean, 4.5 times). In 12 cases of partial bone sclerosis, the infection control time was 7-12 days (mean, 8.3 days); the bone healing time was 24-31 weeks (mean, 27.3 weeks); and the frequency of VSD was 3-5 times (mean, 3.6 times). Infection recurred in 1 case, and the patient gave up the therapy. No infection recurrence was observed in the other patients. ConclusionThe VSD combined with open bone graft is an effective method for the treatment of tibial traumatic osteomyelitis.

Objective To evaluate the effectiveness of Ilizarov external fixation and ankle arthrodesis in the treatment of late traumatic ankle arthritis. Methods Between June 2013 and June 2015, 27 patients with late traumatic ankle arthritis were treated with Ilizarov external fixation technique. There were 16 males and 11 females with an age of 27-69 years (mean, 45.7 years). Sixteen cases were on the left side, 11 on the right side. All the patients suffered from traumatic ankle fractures or ligament damages caused by initial traumas. After 6 months of standard conservative treatment, the results was invalid and all patients had ankle joint pain and movement disorders. The disease duration was 3-39 years (mean, 11.5 years). According to Takakura ankle arthritis staging, there were 16 cases in stage 3 and 11 cases in stage 4. The tibial-talar angle before operation was (102.55±4.02) ° measured on conventional double-feet loading anteroposterior and lateral X-ray films. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and foot joint score was 45.72±6.45, and the visual analogue scale (VAS) score was 8.61±1.96. Results All the patients were followed up 15-42 months (mean, 28.1 months). All ankles achieved bony fusion, the clinical healing time was 12.9 weeks on average (range, 11-18 weeks). No persistent bleeding in the incisions and needle tract occurred during the follow-up. There were 4 cases of mild needle infection, 2 cases of anterior dislocation of talus, and 3 cases with different degree of limited activity. No traumatic bone defect, bone disconnection, and false joint formation was observed. At 12 months after operation, the AOFAS ankle and foot joint score, VAS score, and tibial-talar angle were 80.53±9.14, 2.77±0.82, and (94.36±2.48)°, respectively, which were significantly improved when compared with preoperative ones (t=16.17, P=0.00; t=14.28, P=0.00; t=9.01, P=0.00). The effectivenss was excellent in 9 cases, good in 13 cases, and fair in 5 cases, with an excellent and good rate of 81.5%. Conclusion Satisfactory effectiveness can be obtained through Ilizarov external fixation and ankle arthrodesis in the treatment of traumatic ankle arthritis, showing certain application prospect, while long-term effectiveness should be comfirmed by large sample randomized controlled trials.
Objective To explore the effectiveness of arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release in the treatment of non-traumatic elbow stiffness. MethodsThe clinical data of 15 patients with non-traumatic elbow stiffness treated with arthroscopic release of elbow joint assisted by medial small incision ulnar nerve release between April 2019 and September 2023 were retrospectively analyzed. There were 6 males and 9 females with an average age of 46 years ranging from 34 to 56 years. The causes included rheumatoid arthritis in 3 cases, gouty arthritis in 2 cases, loose bodies in 3 cases, and elbow osteoarthritis in 7 cases. There were 4 cases with ulnar neuritis and 3 cases with synovial osteochondromatosis. The duration of elbow stiffness ranged from 6 to 18 months, with an average of 10 months. The operation time and intraoperative blood loss were recorded. The effectiveness was evaluated by visual analogue scale (VAS) score, range of elbow motion (maximum flexion, maximum extension, and total flexion and extension), Mayo score, and Hospital for Special Surgery (HSS) elbow score. ResultsThe operation time was 60-90 minutes, with an average of 65 minutes, and the intraoperative blood loss was 40-100 mL, with an average of 62 mL. All patients were followed up 13-18 months, with an average of 14 months. There was no complication such as vascular and nerve injury, poor wound healing, collateral ligament injury, elbow joint space narrowing, osteophyte proliferation, or loose body formation around the joint. At last follow-up, the elbow range of motion (maximum flexion, maximum extension, and total flexion and extension), VAS score, and Mayo score significantly improved when compared with those before operation (P<0.05). The HSS elbow score was 85-95, with an average of 92; 12 cases were excellent, 3 cases were good, and the excellent and good rate was 100%. ConclusionArthroscopic release of elbow joint assisted by medial small incision ulnar nerve release is an effective way to treat non-traumatic elbow stiffness, which has the advantages of small trauma, short operation time, and good effectiveness. It can carry out early elbow rehabilitation training and significantly improve elbow function.
Objective To investigate the effectiveness of lateral closing wedge osteotomy for treatment of traumatic cubitus varus deformity in children. Methods Between July 1996 and June 2010, 20 cases of traumatic cubitus varus deformity after humeral supracondylar fracture were treated by lateral closing wedge osteotomy. There were 13 boys and 7 girls, aged from 7 to 14 years (mean, 10.6 years). The left elbow was involved in 12 cases and right elbow in 8 cases. Thirteencases had received closed reduction, percutaneous Kirschner wire fixation, and external fixation in other hospital, and 7 cases misdiagnosed as elbow luxation and soft tissue injury had given external fixation. Cubitus varus deformity occurred at 2-12 years after injury. Preoperatively, the elbow range of motion (ROM) in flexion and extension was 100-150° (mean, 133.0°) and 0-24° (mean, 11.7°), respectively. The angle of cubitus varus deformity was 20-50° (mean, 32.1°). Results All incisions healed by first intention, and no related complication occurred. A total of 17 patients were followed up 1-14 years (mean, 5 years). X-ray films revealed that bone union was achieved in all cases within 5-8 weeks after operation (mean, 6 weeks). The deformity of cubitus varus was corrected in all cases. At last follow-up, the elbow ROM in flexion and extension was 110-150° (mean, 135.9°) and 0-27° (mean, 12.9°), respectively. According to Jupiter et al. elbow score system, the results were excellent in 14 cases, good in 2 cases, and fair in 1 case; the excellent and good rate was 94.1%. One patient underwent recurrence at 1 month after removal of the Kirschner wire, and lateral closing wedge osteotomy was performed again after 1 year. Conclusion Lateral closing wedge osteotomy is a safe and effective surgical procedure in correcting traumatic cubitus varus deformity in children, which is easy to operate and can be effective in reducing the complications.
Objective To investigate the effectiveness of calcaneal V-shaped osteotomy combined with subtalar arthrodesis in the treatment of Stephens Ⅱand Ⅲ calcaneal fracture malunion. MethodsThe clinical data of 24 patients with severe calcaneal fracture malunion treated by calcaneal V-shaped osteotomy combined with subtalar arthrodesis between January 2017 and December 2021 were retrospectively analyzed. There were 20 males and 4 females with an average age of 42.8 years (range, 33-60 years). Conservative treatment of calcaneal fracture failed in 19 cases and operation failed in 5 cases. Stephens classification of calcaneal fracture malunion was type Ⅱ in 14 cases, and type Ⅲ in 10 cases. Preoperative Böhler angle of calcaneus was 4.0°-13.5° (mean, 8.6°), Gissane angle was 100°-152° (mean, 119.3°). The time from injury to operation was 6-14 months (mean, 9.7 months). American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analogue scale (VAS) score were used to evaluate the effectiveness before operation and at last follow-up. Bone healing was observed and the healing time was recorded. The talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were measured. Results Necrosis of the cuticle edge of the incision occurred in 3 cases, which were cured by dressing change and oral administration of antibiotic therapy. The other incisions healed by first intention. All the 24 patients were followed up 12-23 months, with an average of 17.1 months. The foot shape of the patients recovered well, the shoes were restored to the size before injury, and there was no anterior ankle impingement. Bone union was achieved in all patients, and the healing time ranged from 12 to 18 weeks, with an average of 14.1 weeks. At last follow-up, no adjacent joint degeneration occurred in all patients; 5 patients had mild foot pain during walking, which had no significant impact on daily life and work; no patient needed revision surgery. The AOFAS ankle and hindfoot score was significantly higher than that before operation (P<0.001), the results were excellent in 16 cases, good in 4 cases, and poor in 4 cases, and the excellent and good rate was 83.3%. The VAS score, talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were significantly improved after operation (P<0.001). ConclusionCalcaneal V-shaped osteotomy combined with subtalar arthrodesis can effectively relieve hindfoot pain, correct talocalcaneal height, restore talus inclination angle, and reduce the risk of nonunion after subtalar arthrodesis.
