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 evaluate the operative methods and therapeutic effects of nasal septum cartilage-sil ica gel complex for two-stage repair of nasal deformities of unilateral cleft l ip. Methods From June 2001 to June 2007, 38 cases of secondary nasal deformity and septum deviation of cleft l ip were treated with transplanting nasal septum cartilage-sil ica gelcomplex. Among of them, there were 21 males and 17 females, aging 14-23 years with an average of 17.6 years. All cases were with nasal deformities of unilateral cleft l ip, including 21 cases of complete cleft l ip and 17 cases of incomplete cleft l ip. The locations were left side in 26 cases and right side in 12 cases. Nasal deformities were columella nasi deflexion, flattened nasal tip, pteleorrhine and alanasi collapse. The patients received 1-4 times operations, and the interval of two operations was 3-10 years (mean 5.5 years). According to nasal deformity, the nasal septum cartilage of 1.8 cm × 1.2 cm was cut, and transplanted into the nose point phantom surface forming “the shield” to extend nose column and to raise the tip of the nose. At the same time the nasal tip fat-connective tissue flap graft with fat knot was given. After fixation, the nasal alar cartilage and soft tissues were reduced to normal position. Results Primary heal ing of the incisions was achieved in all cases. The nasal deformity was corrected. The postoperative follow-up period was 12-18 months with an average of 15.6 months. All the patients of regional cartilage scars had no compl ication. The figure of nose was sl inky, the height of apex of nose and the shape of nose was natural,the apex of nose, nasal ala, nostrils and nasal columella were satisfactory [(the results were satisfactory in 30 cases (78.9%), general in 8 cases (21.1%)]. The nose department overall esthetics shape was improved in all the patients, no compl ications of the phantom sl iding, shifting and exposure, hemorrhage and infection occurred. Conclusion The nasal septum cartilagesil ica gel complex to repair the nasal deformities of unilateral cleft l ip is an ideal operation style.
To analyze the effectiveness of posterior pedicle screw system combined with interbodyfusion in treating lumbar spondylol isthesis. Methods Between January 2005 and January 2009, 26 patients with lumbar spondylol isthesis underwent posterior pedicle screw system combined with interbody fusion, including 11 males and 15 females with an average age of 56.8 years (range, 36-73 years). The disease duration was 7 months to 11 years. The affected lumbars were L3 in 3 cases, L4 in 12 cases, and L5 in 11 cases. According to the Meyerding evaluating system, 21 cases were classified as degree III, 5 cases as degree III-IV, and 1 case as degree IV. The cl inical results were investigated by measuring radiographic measurements, including Taillard index, Boxall index, sl i pping angle, lumbar lordosis angle,and intervertebral height index preoperatively, immediately, 2 weeks and 3 months postoperatively, respectively. SUK’s criteria was used to judge bone graft fusion. Results Primary heal ing of the incisions was achieved in all cases. Allpatients were followed up 25.8 months on average (range, 10-51 months). There were significant differences in Taillardindex, Boxall index, sl i pping angle, lumbar lordosis angle, and intervertebral height index between preoperatively andimmediately, 2 weeks, 3 months after operation (P lt; 0.05). Bone graft fusion was achieved at 3-8 months after operation(mean, 3.5 months); and the fusion rate was 100%. According to Japanese Orthopedic Association (JOA) scoring, theresults were excellent in 17 cases, good in 7 cases, fair in 1 case, and poor in 1 case; and the excellent and good rate was 92.3%. Compl ications occurred in 2 cases, including nail or rod breakage and nerve injury, and they were cured aftertreatment. Conclusion Posterior pedicle screw system combined with interbody fusion treating lumbar vertebralspondylol isthesis can afford sol id internal fixation and achieve a satisfactory reduction, so it maybe an ideal procedure and a worthy recommended method for treating lumbar spondylol isthesis.
Objective To investigate the cl inical outcomes of one stage debridement and closed-suction drainage for treatment of infection after lumbar instrumentation. Methods Between June 2002 and March 2008, 12 patients with infection after lumbar instrumentation were treated with one stage debridement and closed-suction drainage, including 9 males and 3females and aging 35-68 years (48.5 years on average). The disease duration varied from 7 days to 183 days (56 days on average). The segments of internal fixation included 7 cases single segment at levels of L4, 5, 4 cases of double segments at levels of L 4, 5, L5, S1 (2 cases), and L3, 4, L4, 5 (2 cases), and 1 case of three segments at levels of L3, 4, L4, 5, L5, S1. Two patients were treated with internal fixator removal. Results The bacterial culture results of intervertebral discs were positive in 8 cases for Staphylococcus aureus and in 3 cases for Enterobacter cloacae, negative in 1 case. Primary healing of incisions were achieved in all cases. Twelve patients were followed up 18-53 months (34.7 months on average). The white blood cell count, erythrocyte sedimentation rate, and C reactive protein significantly decreased after operation, showing significant differences at 15 days after operation when compared with those before operation (P lt; 0.05). No obvious low back pain was observed. Pathological-changed vertebra-space fused. No displacement and breakage of internal fixator occurred; in 2 patients who were given internal fixator removal, no removal of the instrumentation was performed again. The X-ray films showed that the average kyphosis decreased 0.8° at 18 months after operation. At last follow-up, the visual analogue scale score was 2 ± 1, showing significant difference (P lt; 0.05) when compared with that (10 ± 2) before operation. Conclusion One stage debridement and closed-suction drainage therapy is an effective method for treating infection after lumbar instrumentation. The operation is easy and can reduce hospitalization days.
Objective To observe the cl inical outcome of treating blepharophimosis-ptosis-epicanthus inversus syndrom (BPES) by means of primary and complex recection of levator palpebrae superioris musculus. Methods From May 2001 to May 2007, 12 patients with BPES were treated, including 6 males and 6 females aged 4-15 years old (average 7 years old).All patiens marked signs of BPES— typical ptosis of the upper eyel ids, epicanthus inversus, palpebral fissure, and increased distance between inner canthus.The eye fissure width was (2.8 ± 1.8) mm, the eye fissure length was (19.8 ± 4.7) mm, and the inner canthic diameter was (41.6 ± 6.5) mm.The muscular strength of levator palpebrae superioris was deficient in 4 cases, the muscular strength of levator palpebrae superioris was (2.0 ± 0.6) mm in 8 cases.All patients were associated with visual function congenital defects of varying degrees.The surgical technique included shortening of the internal canthal l igaments, recection of the tarsus and levator muscle, and skin plasty. Results All the incisions healed by first intension.Twelve patients were followed up for 12-48 months (average 30 months).Amel ioration of ptosis and epicanthus was achieved.At 18 months after operation, the eye fissure width of 10 petients was (9.0 ± 2.1) mm, the eye fissure length was (26.5 ± 3.5) mm, and inner canthic diameter was (30.2 ± 2.7) mm, the muscular strength of levator palpebrae superioris increased to (5.6 ± 1.9) mm, showing significant difference when compared with preoperation (P lt; 0.05). Conclusion The primary and complex recection of levator palpebrae superioris musculus can provide relating good cosmetic and functional results for the correction of BPES. Patients with BPES should receive surgery as early as possible.
