    ABSTRACT: STUDY DESIGN:: To review the study of severe upper thoracic scoliosis (>90 degrees) in adolescence treated with pedicle screw constructs. OBJECTIVE:: The purpose of the present study was to analyze the treatment for upper thoracic scoliosis in adolescence. SUMMARY OF BACKGROUND DATA:: Upper thoracic scoliosis is an uncommon spinal deformity in young children. Upper thoracic scoliosis is special. METHODS:: There were 21 patients (11 boys and 10 girls) with severe upper thoracic scoliosis and their mean age was 15 years (range, 13-18 y). The mean Cobb angle was 102.2 degrees (90-118 degrees) The clavicle angle ranged from 18 to 23 degrees, with an average of 21 degrees. Patients with the major curve of scoliosis located in the upper thoracic spine were treated with a posterior spinal fusion with a pedicle screw-only construct. There was a minimum 2-year follow-up. Follow-up information was obtained clinically and radiologically. RESULTS:: All patients underwent a posterior spinal fusion with a pedicle screw-only construct. Their shoulders were nearly balanced. The preoperative major curve was 102.2±8.9 degrees with a flexibility of 25.8%±8.1% in a side-bending film. The deformity was corrected to 29.7±5.9 and 32.1±5.6 degrees at the most recent follow-up. There was a 3.9-degree correction loss during the postoperative follow-up. There were no neurological or vascular complications at 2 years of follow-up. There was no crankshaft phenomenon. CONCLUSIONS:: The pedicle screw constructs can be safely used for severe upper thoracic scoliosis. Curve correction is powerful for these curves, which are stiff and difficult to manage. Screw accuracy was excellent in this review.

    ABSTRACT: To investigate the clinical effects of the minimal invasive osteotomy treatment for hallux valgus combined with tailor's bunion deformity. From May 2007 to May 2009, Forty-nine feet of 32 patients (a mean age of 57 years old) of hallux valgus combined with tailor's bunion deformity were reviewed retrospectively, including 2 males(2 feet) and 30 females (47 feet). All patients were treated by the minimal invasive osteotomy. The axial and lateral films of all feet with loading were taken before and after operation. The hallux abducto valgus angle(HAV),intermetatarsal angle(IM), fourth-fifth intermetatarsal angle (IM 4 to 5), modified fourth-fifth intermetatarsal angle (MIM 4 to 5), Metatarsophalangeal-fifth angle (MPA) and lateral deviation of the fifth matatarsal angle (LDA) were compared before and after operation. Therapeutic effects of all the patients were observed after operation, the item including AFAS score and WEN Jian-min's therapeutic effects standard. The average operating time was 40 minutes. All the patients were followed up,and the duration ranged from 6 to 24 months. The HAV angle, IM angle, IM 4 to 5 angle, MIM 4 to 5 angle,MPA angle and LDA angle significantly decreased after operation. The AFAS score significantly raised after operation. According to the criteria, 33 feet got an excellent result, 15 good and 1 fair. The minimal invasive osteotomy treatment for hallux valgus combined with tailor's bunion is effective and safe. This method is mini-trauma,less pain and it can make a very soon rehabilitation. This method has widely clinical value.
