Objective To systematically review literature on the influencing factors related to adolescent sub-health problems. Methods We electronically searched the following four databases including CBM, VIP, CNKI and WanFang Data to collect Chinese literature on adolescent sub-health status and problems in China published before May 2012. Two reviewers independently screened literature, extracted data, and cross checked records. Then qualitative analysis was applied. Results According to the inclusion and exclusion criteria, 41 cross-sectional studies were included. The results of qualitative analysis showed that the influencing factors of adolescent sub-health could be classified into four categories including social factors, family factors, school factors, and interpersonal relationships. The main ones were social support, employment pressure, family economic conditions, learning burden, unhealthy habits, etc. Conclusions There are many influencing factors of adolescent sub-health with interaction. Due to the limitation of the included studies, more prospective cohort studies are needed to provide high quality evidence.

Objective To investigate the effectiveness of arthroscopic medial retinaculum plication (MRP) for acute patellar dislocation (APD) in adolescents. Methods Between March 2007 and June 2011, 24 adolescent patients suffering from APD were treated by arthroscopic MRP. There were 14 males and 10 females, aged 8-18 years (mean, 12.7 years). The location was the left knee in 16 cases and the right knee in 8 cases. Injury was caused by sports in 19 cases, by traffic accident in 4 cases, and by heavy bruising in 1 case. The duration from injury to operation was 3 to 21 days with an average of 7.8 days. The results of floating patella test and dislocation apprehension test were both positive. MRI examination showed the arthroedema in all cases; associated injuries included medial retinaculum injury in 20 cases, medial patellar injury in 8 cases, and meniscus tear in 5 cases. Results All incisions healed by first intention without complication of infection or neurovascular injury. All the patients were followed up 12-36 months (mean, 14.6 months). Only 2 patients suffered from patellar re-dislocation at 4 months and 6 months after operation respectively. The knee joint activity returned to normal at 12 months. The Lysholm, Kujala, and International Knee Documentation Committee (IKDC) scores at 3 and 12 months after operation were significantly higher than those before operation (P lt; 0.05), and the scores at 12 months were significantly higher than those at 3 months (P lt; 0.05). Conclusion Treatment of APD with arthroscopic MRP has the advantages of minor trauma and good knee functional improvement. The technique can decrease incidence of patellar re-dislocation in adolescent.
Objective To review and summarize the surgical techniques and their outcomes for the treatment of lumbar spondylolysis in young patients by direct surgical repair. Methods Both home and abroad literature on the surgical techniques and their outcomes respectively for the treatment of lumbar spondylolysis in young patients by direct surgical repair was reviewed extensively and summarized. Results Direct surgical repair of lumbar spondylolysis can offer a simple reduction and fixation for the injured vertebra, which is also in accord with normal anatomy and physiology. In this way, normal anatomy of vertebra can be sustained. As reported surgical techniques of direct repair, such as single lag screw, hook screw, cerclage wire, pedicle screw cable, pedicle screw rod, and pedicle screw hook system, they all can provide acceptable results for lumbar spondylolysis in young patients. Furthermore, to comply strictly with the inclusion criteria of surgical management and select the appropriate internal fixation can also contribute to a good effectiveness. Within the various methods of internal fixation, pedicle screw hook system has been widely recognized. Conclusion Pedicle screw hook system fixation is simple and safe clinically. With the gradual improvement of this method and the development of minimally invasive technologies, it will have broad application prospects.
Objective To compare the rib regeneration in patients with adolescent idiopathic scoliosis (AIS) after convex short length rib resection or conventional thoracoplasty. Methods Between January 2005 and December 2009, 36 patients with Lenke 1 AIS underwent posterior correction, instrumentation, and fusion, and the clinical data were retrospectively analyzed. Conventional thoracoplasty was performed in group A (n=14), convex short length rib resection in group B (n=22). There was no significant difference in gender, age, Cobb angle of major curve, flexibility, and preoperative rib hump between 2 groups (P gt; 0.05). The standing long-cassette anteroposterior and lateral X-ray films of spine were taken at 3 months, 6 months, l year, and 2 years respectively after operation. Rib regeneration classification established by Philips was used to analyze the rib formation. Results All patients were followed up 32 months on average (range, 24-48 months). Cobb angle of major curve and rib hump were significantly improved when compared with preoperative values in 2 groups (P lt; 0.05), and there was no obvious correction loss. At each time point after operation, there was no significant difference in Cobb angle of major curve between 2 groups (P gt; 0.05), but the rib humb of group B was significantly bigger than that of group A (P lt; 0.05). The rib regeneration in group B was better than that in group A, showing significant difference (P lt; 0.05). At 3 months after operation, 80.0% rib regeneration was below grade 4 in group A, and 96.3% rib regeneration reached grade 4 or above in group B. At 2 years after operation, 52.0% and 96.3% rib regeneration reached grade 6 or above in groups A and B, respectively. Conclusion The rib regeneration in patients with AIS after convex short length rib resection is better than that after conventional thoracoplasty.
【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.
Objective To explore the effectiveness of arthroscopic medial retinaculum pl ication (MRP) for recurrent patellar dislocation in adolescents. Methods Between March 2000 and October 2007, 30 adolescent patients with recurrent patellar dislocation underwent arthroscopic MRP, and 28 of them (12 left knees and 16 right knees) completed thefinal follow-up and were enrolled. There were 5 males and 23 females with an average age of 14.7 years (range, 12-19 years). The dislocation duration was 4 to 39 months with an average of 18.8 months. All patients experienced 2-4 episodes of dislocation. Before operation, all the patients showed positive apprehension test; the degree of lateral patellar translation was (2.9 ± 0.7)° and there was no hardness termination in lateral translation. The International Knee Documentation Committee (IKDC), Lysholm, Kujala, and Tegner scores were 47.7 ± 3.7, 52.6 ± 4.9, 66.7 ± 5.9, and 3.1 ± 1.3, respectively. All patients underwent arthroscopic MRP procedure. Results All incisions healed by first intention without compl ication. All the patients were followed up 2-7 years (4.8 years on average). During the follow-up, more and more patients showed positive apprehension test, and at 24 months of follow-up, 12 patients showed positive apprehension test; less and less patients had hardness termination in lateral translation, only 3 patients at 24 months of follow-up; the degree of lateral patellar translation increased, (2.3 ± 1.1)° at 24 months of follow-up. There were significant differences in positive apprehension test and hardness termination between preoperation and 24 months of follow-up (P lt; 0.05). Moreover, 6 patients suffered from redislocation, and 23 patients experienced patella instabil ity. The IKDC, Lysholm, Kujala, and Tegner scores at 24 months of follow-up were 62.5 ± 6.2, 70.7 ± 5.1, 76.6 ± 4.8, and 3.9 ± 0.7, respectively, showing significant differences when compared with preoperative scores (P lt; 0.05). CT examination showed that the congruence angle, lateral patellar angle, and patellar tilt angle were recovered to normal level after operation immediately, however, the final patellar position at 24 months of follow-up was not significantly betterthan that before surgery (P gt; 0.05). There was significant difference in the lateral patellar displacement between preoperation and 24 months of follow-up (P lt; 0.05). Conclusion Arthroscopic MRP is not rel iable for maintaining the corrected position of the patella for recurrent patellar dislocation in adolescents, though functional improvements are significant.
Objective To analyze the cl inical results of different surgical approaches in treating hallux valgus deformity in children and adolescents. Methods From April 2000 to April 2007, 18 cases of hallux valgus deformity (30 feet) were treated. According to different ages, they were divided into children group ( 10 years) and adolescent group (11-18 years). In children group, 4 female patients included 2 bilateral and 2 unilateral hallux valgus deformity (2 left feet, 4 right feet). Each patient underwent a combination of Austin osteotomy and McBride procedure. The American Orthopaedic Foot and AnkleSociety-Hallux Metatarsophalangeal Interphalangeal (AOFAS-HMI) score was 55.0 ± 15.0, and the visual analogue scale (VAS) score was 6.0 ± 2.0. The hallux valgus angle (HVA) and 1st-2nd intermetatarso-phalangeal angle (IMA) were (35.0 ± 4.0)° and (14.4 ± 2.0)°. In adolescent group, 14 patients included 3 males (4 feet) and 11 females (20 feet), 10 bilateral and 4 unilateral hallux valgus deformity (10 left feet, 14 right feet). Each patient underwent the modified Mitchell osteotomy. The AOFAS-HMI score was 55.6 ± 14.0, and the VAS score was 7.0 ± 1.0. The HVA and IMA were (38.5 ± 5.0)° and (15.0 ± 3.0)°. Results All incisions healed primarily. The patients of two groups were followed up 12-32 months (21 months on average). In adolescent group, pain of metatarsophalangeal joint occurred in 1 case and the symptom disappeared after 3-month physical therapy; 1 case recurred after 21 months of operation and achieved satisfactory results after Lapidus operation. In children group, the AOFASHMI score was 92.1 ± 5.0, the VAS score was 1.0 ± 0.6, HVA was (14.7 ± 3.0)°, and IMA was (5.5 ± 2.0)°; showing significant differences (P lt; 0.05) when compared with those before operation. In adolescent group, the AOFAS-HMI score was 90.0 ± 6.0, the VAS score was 1.0 ± 0.6, HVA was (13.7 ± 3.0)°, and IMA was (6.8 ± 2.0)°; showing significant differences (P lt; 0.05) when compared with those before operation. Conclusion It has the advantages of rapid bone heal ing, short course of treatment, and less compl ication to treat hallux valgus deformity in children with a combination of Austin osteotomy and McBride procedure and in adolescent with the modified Mitchell osteotomy.
Objective To analyze the cl inical features of scol iosis associated with Chiari I malformation in adolescent patients, and to explore the val idity and safety of one-stage posterior approach and vertebral column resection for the correction of severe scol iosis. Methods Between October 2004 and August 2008, 17 adolescent patients with scol iosis associated with Chiari I malformation were treated with surgical correction through posterior approach and pedicle instrumentation. There were 9 males and 8 females with an average age of 15.1 years (range, 12-19 years). The MRI scanning showed that 16 of 17 patients had syringomyel ia in cervical or thoracic spinal cord. Apex vertebra of scol iosis were located atT7-12. One-stage posterior vertebral column resection and instrumental correction were performed on 9 patients whose Cobb angle of scol iosis or kyphosis was more than 90°, or who was associated with apparent neurological deficits (total spondylectomy group). Other 8 patients underwent posterior instrumental correction alone (simple correction group). All patients’ fixation and fusion segment ranged from upper thoracic spine to lumbar spine. Results The operative time and the blood loss were (384 ± 65) minutes and (4 160 ± 336) mL in total spondylectomy group, and were (246 ± 47) minutes and (1 450 ± 213) mL in simple correction group; showing significant differences (P lt; 0.05). In total spondylectomy group, coagulation disorder occurred in 1 case, pleural perforation in 4 cases, and lung infection in 1 case. In simple correcction group, pleural perforation occurred in 1 case. These patients were improved after symptomatic treatment. All patients were followed up 24-36 months (32.5 months on average). Bony heal ing was achieved at 6-12 months in total spondylectomy group. No breakage or pull ingout of internal fixator occurred. The angles of kyphosis and scol iosis were significantly improved at 1 week after operation (P lt; 0.01) when compared with those before operation. The correction rates of scol iosis and kyphosis (63.4% ± 4.6% and 72.1% ± 5.8%) in total spondylectomy group were better than those (69.4% ± 17.6% and 48.8% ± 19.3%) in simple correction group. Conclusion Suboccipital decompression before spine deformity correction may not always be necessary in adolescent scol iosis patients associated with Chiari I malformation. In patients with severe and rigid curve or apparente neurological deficits, posterior vertebral column resection would provide the opportunity of satisfied deformity correction and decrease the risk of neurological injury connected with surgical correction.
