Objective To study the effect of microtraumatic treatment of postoperative recurrent bone cysts in juvenile patients. Methods FromDecember 1984 to December 2003, 36 cases of postoperative recurrent bone cysts after focal curettage and bone graft included 19 males and 17 females, aging 9-21 years-with an average of 15 years. The size of bone cyst ranged from 2.5 cm×6.0 cm to 3.5 cm×13.0 cm with an average of 3.0 cm×8.0 cm. The locations were proximal humerus in 18 cases, humeral shaft in 10 and femoral trochanteric region in 8. The focal curette and bonegraft were given once in 23 cases, twice in 10 cases and 3 times in 3 cases. The interval between recurrence and microtraumatic treatment was 5-13 months (6.5 months on average). The posteroanterior and lateral X-ray films were takento determine the location, range and feature of the focus. Under local anesthesia, 2 canulated needles were used; one was used to aspirate the contents of the cyst, the other was used to inject hydrocortisone acetate. The dose was determined according to the range of the focus. The treatment was repeated every 3.54 months until the focus healed. Results All patients were followed up from 3 to 18 years with an average of 5 years. The microtraumatic treatment was repeated 3-11 times with an average of 6 times. Twenty-six cases healed completely, 6 cases healed significantly, and 4 cases healed partially. No local or general complications occurred during the treatment. Conclusion This microtraumatic method for the treatment of postoperative recurrent bone cyst in juvenile patients has following advantages : less pain, easy manipulation, no hospitalization, low cost and definite effect.

Objective To explore the effect of arthroscopy in diagnosis and treatment of osteochondritis dissecans of elbow joint in adolescent. Methods From May 2003 to February 2006, 11 patients with osteochondritis dissecans of elbowjoint were diagnosed and treated with arthroscopy. There were 6 males and 5 females, aging from 13 to 19 years. The left joints were involved in 4 cases and right joints in 7 cases. Seven patients had obvious history of injury. The interval of injury and operation was from 7 months to 12 years. The score of VAS was 80±10, the range of flexion and extend of joint 80±10°, the range of rotation of joint 100±5° preoperatively. The brachial plexus anesthesia, the elbow hung to traction, soft spot, interna and extrapathway were given to explore and debride elbow joint and remove corpus liberum. Results All patients recovered daily life and work 7 to 12 dayspostoperatively. There were no complications of blood vessel and nerve injuries. Eleven cases were followed up for 6 to 18 months (mean 12-5 months). The results wereexcellent in 7 and good in 4 according to HSS scoring system. At the final followup, the score of VAS was 32±15, showing statistically significant difference when compared with preoperation (Plt;0.05). The range of flexion and extend of joint was 110±10°，the range of rotation of joint was 120±5° postoperatively, showing statistically significant differences when compared with preoperation (Plt;0.05). Conclusion The elbow arthroscopy might be a reliable methodto diagnose and treat osteochondritis dissecans of elbow joint in adolescent with minor trauma，quick recovery，significant improving function and less complications.
ObjectiveTo evaluate the clinical results of arthroscopic treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fractures in adolescents with epiphyseal unclosure. MethodsBetween January 2011 and October 2013, 35 knees with ACL tibial eminence avulsion fractures (35 patients with epiphyseal unclosure) were arthroscopically treated with suture fixation. There were 25 males and 10 females, aged 8-16 years (mean, 14.7 years). The causes included sports injury in 24 cases, traffic accident injury in 9 cases, and daily life injury in 2 cases. According to Meyers-McKeever classification criteria, there were 27 cases of type Ⅱ and 8 cases of type Ⅲ. Five cases had meniscus injury. The preoperative the International Knee Documentation Committee (IKDC) score was 48.7±3.2, and Lysholm score was 51.2±4.5. The time from injury to operation was 2-16 days (mean, 5 days). ResultsPrimary healing of incision was obtained in all patients. The mean follow-up time was 22.4 months (range, 12-32 months). Anatomical reduction was achieved in 28 cases and satisfactory reduction in 7 cases. X-ray films showed all fractures healing at last follow-up. There was no limb shortening deformity, varus knee, or valgus knee. Lachman test results were all negative. The other knees had normal range of motion except 1 knee with limited flexion, whose range of motion returned to 0-120° after treatment. At last follow-up, the IKDC score was significantly improved to 93.2±4.1 (t=-53.442, P=0.000), and the Lysholm score was significantly increased to 96.2±2.5 (t=-56.242, P=0.000). ConclusionThe arthroscopic fixation technique has satisfactory results for the reduction and fixation of ACL tibial eminence avulsion fracture in the adolescents with epiphyseal unclosure because of little trauma and quick recovery.
ObjectiveTo systematically review the methodological quality of guidelines concerning attention-deficit/hyperactivity disorder (ADHD) in children and adolescents, and to compare differences and similarities of the drugs recommended, in order to provide guidance for clinical practice. MethodsGuidelines concerning ADHD were electronically retrieved in PubMed, EMbase, VIP, WanFang Data, CNKI, NGC (National Guideline Clearinghouse), GIN (Guidelines International Network), NICE (National Institute for Health and Clinical Excellence) from inception to December 2013. The methodological quality of included guidelines were evaluated according to the AGREE Ⅱ instrument, and the differences between recommendations were compared. ResultsA total of 9 guidelines concerning ADHD in children and adolescents were included, with development time ranging from 2004 to 2012. Among 9 guidelines, 4 were made by the USA, 3 in Europe and 2 by UK. The levels of recommendations were Level A for 2 guidelines, and Level B for 7 guidelines. The scores of guidelines according to the domains of AGREE Ⅱ decreased from "clarity of presentations", "scope and purpose", "participants", "applicability", "rigour of development" and "editorial independence". Three evidence-based guidelines scored the top three in the domain of "rigour of development". There were slightly differences in the recommendations of different guidelines. ConclusionThe overall methodological quality of ADHD guidelines is suboptimal in different countries or regions. The 6 domains involving 23 items in AGREE Ⅱ vary with scores, while the scores of evidence-base guidelines are higher than those of non-evidence-based guidelines. The guidelines on ADHD in children and adolescents should be improved in "rigour of development" and "applicability" in future. Conflicts of interest should be addressed. And the guidelines are recommended to be developed on the basis of methods of evidence-based medicine, and best evidence is recommended.
【Abstract】 Objective To observe the effectiveness of limited operations and Ilizarov techniques for correction of congenital clubfoot (CCF) in adolescents, and to explore the new methods and new ideas for functional reconstruction of CCF. Methods Between September 2003 and July 2010, 25 adolescent patients (40 feet) with CCF were treated. Of the 25 patients, 14 were male (20 feet) and 11 were female (20 feet) with an age range from 12 to 25 years (mean, 15.7 years). The left feet were involved in 4 cases, the right feet in 6 cases, and both feet in 15 cases. According to Qin’s clubfoot deformity scale, 9 feet were rated as degree I, 17 feet as degree II, and 14 feet as degree III. In these cases, 9 feet were accompanied by internal rotation deformities of crus and 1 case by subluxation of right hip joint. After soft tissue release and osteotomy, 9 feet (degree I) were fixed by composite external fixation instruments, 31 feet by Ilizarov external fixation instruments. The deformity was corrected from 5 to 7 days after operation with distraction of 0.5-1.0 mm/d, then distraction stopped when the ankle was corrected at a hyperextension of 5 to 10° and light valgus. The affected limb might undergo weight bearing walking with external fixation at corrected position for 4 to 6 weeks. If one had both feet deformity, staged operation should be performed with a surgery interval of 3 to 6 months (mean, 4 months). Results The fixation time was 6-12 weeks (mean, 8 weeks) in 9 feet fixed by composite external fixation instruments, and it was 6-17 weeks (mean, 13 weeks) in 31 feet fixed by Ilizarov external fixation. All 25 patients were followed up 8 months to 6 years with an average of 37 months. During distraction process, slight pin track infection occurred in 6 cases (6 feet), which were cured after expectant management. One patient had recurrence of the deformity at 2 years postoperatively, who obtained satisfactory correction after Ilizarov external fixation for 4 weeks. The satisfactory correction and foot function were achieved in the other feet with walking on full weight-bearing. According to International Clubfoot Study Group (ICFSG) score, the results were excellent in 28 feet, good in 10 feet, and fair in 2 feet, with an excellent and good rate of 95% at last follow-up. Conclusion Combined limited operation with Ilizarov technique for correcting adolescent CCF is accord with biology principle and minimally invasive surgical principle, so it is a safe，minimally invasive, and effective method. It also can broaden the operative indications and correct degree III talipes equinovarus which is unattainable by traditional orthopedic surgery.
