Objective : To determine deformity correction by postural correction and subsequent balloon inflation in acute vertebral compression fractures (OVCFs) and to examine the effect of bone mineral density on deformity correction. Methods : A totol of 50 acute OVCFs received balloon kyphoplasty. Lateral radiographs were taken and analyzed at five different time points : 1) preoperative, 2) after placing the patient in prone hyperextended position, 3) after balloon inflation, 4) after deposition of the cement, and 5) postoperative. All fractures were analyzed for height restoration of anterior (Ha), middle (Hm) and posterior (Hp) vertebra as well as Cobb angle and Kyphotic angle. The bone mineral density (BMD) of lumbar spine was measured by dual-energy X-ray absorptiometry. According to the T-score, the patients were divided into two groups which were osteoporosis group and osteopenia group. Results : Postoperative measurements of Ha, Hm and the Cobb angle demonstrated significant reduction of 4.62 mm, 3.66 mm and $5.34^{\circ}$ compared with the preoperative measurements, respectively (each p<0.05). Postural correction significantly increased Ha by 5.51 mm, Hm by 4.35 mm and improved the Cobb angle by $8.32^{\circ}$ (each p<0.05). Balloon inflation did not demonstrate a significant improvement of Ha, Hm or the Cobb angle compared with baseline prone hyperextended. Postural correction led to greater improvements of Ha, Hm and Cobb angle in osteoporosis group than osteopenia group (each p<0.05). Conclusion : In acute OVCFs, the height restoration was mainly attributed to postural correction rather than deformity correction by balloon inflation. BMD affected deformity correction in the process of postural correction.

Purpose: It is accepted universally that correction of the cleft lip nasal deformity requires multiple stages of surgery. Following primary lip repair in infancy or early childhood, secondary surgery to improve the deformity of the lip and nose is frequently necessary. A suitable surgical procedure to correct the accompanying deformity, such as cleft palate and alveolus, must be carried out at an appropriate age. In developing countries, it is common for patients with cleft lip nasal deformity to present severe secondary deformities in adolescence, because of poor follow-up and inappropriate surgery. Methods: The first patient was a 12 year old Mongolian boy. He presented prominent lip scar, short lip, wide columella, asymmetric nostril, palatal fistula, cleft alveolus, and velopharyngeal incompetence. He underwent cheilorhinoplasty, transpositional flap, alveoloplasty by iliac bone graft, and sphincter pharyngoplasty. On follow-up, a bilateral maxillary hypoplasia and a class III malocclusion developed. He underwent LeFort I osteotomy and maxillary advancement at the age of 16 years. The second patient was an 18 year old Eastern Russian girl. She presented with a deviated nose, right alar base depression, short lip, protrusion on vermilion, large palatal fistula, and severe VPI due to short palate. She underwent the combined procedure of cheilorhinoplasty, corrective rhinoplasty, tongue flap for palatal fistula, and superiorly based pharyngeal flap. And the tongue flap was detached at postoperative 3 weeks. Results: The overall results have been extremely pleasing and satisfactory to patients. There were no postoperative complications. Conclusion: We discovered the one stage operation for radical correction was sufficient procedure to provide excellent clinical outcomes in patients with severe cleft lip nose deformity.

Two patients with funnel chest deformity were corrected in the department of Thoracic Surgery, N.M.C. The first case was a 12 months old male suffering from recurrent upper respiratory tract infection and symmetrical funnel chest deformity, of which hollow cavity was measured 40 ml of water. He was corrected by method of sternal turnover. The result was satisfactory. The second case was a 16 years old male suffering from exertional dyspnea, recurrent upper respiratory tract infection, wheezing sound [esp., at night], and asymmetrical funnel chest deformity, of which hollow cavity was measured 80 ml of water. He was corrected by modified Ravitch method. Until postoperative 4 months, result was satisfactory. Thereafter, respiratory wheezing, exertional dyspnea and chest wall deformity were returned to pre-operative status.

Objectives : The purpose of this study was to evaluate surgical outcomes and complications of spinal deformity associated with neurofibromatosis type-1 (NF-1). Methods : From 2012 to 2018, patients suffering from spinal deformity associated with NF-1 who underwent surgical correction were identified. Demographic data and radiographic measures were retrospectively reviewed. Pre- and postoperative whole spine radiograph images were used to determine both coronal and sagittal Cobb angles. All of patients underwent 3-dimentional computed tomographic scan and magnetic resonance imaging scan to confirm dystrophic features. For evaluation of clinical outcomes, we surveyed the pre- and postoperative scoliosis research society-22r (SRS-22r) score. Results : Seven patients with spinal deformity associated with NF-1 were enrolled in this study. The mean age of patients was 29.5±1.2 years old. The mean follow-up period was 2.8±1.4 years. The apex of the deformity was located in cervicothoracic (n=1), thoracic (n=4), and lumbar region (n=2). Most patients have poor bone quality and decreased bone mineral density with average T-score of -3.5±1.0. All patients underwent surgical correction via posterior approach. The pre- and postoperative mean coronal and sagittal Cobb angle was 61.6±22.6° and 34.6±38.1°, 56.8±18.5° and 40.2±9.1°, respectively. Mean correction rate of coronal and sagittal angle was 44.7% and 23.1%. Ultimate follow-up SRS-22r score (average score, 3.9±0.4) improved comparing to preoperative score (average score, 3.3±0.9). Only one patient received revision surgery due to rod fracture. No serious complication occurred, such as neurological deficit, and viscerovascular injury. Conclusion : The surgical correction of patients having spinal deformity associated with NF-1 is challenging, however the radiographic and clinical outcomes are satisfactory. The all posterior approach can be a safe and effective surgical option for patients having dystrophic curves associated with NF-1.

In spite of all fine methods developed for treating cleft lip, a certain percentage of cases might still need secondary correction. Generally, secondary revision of cleft lip is much difficult to produce esthetic outcome, because the cleft lip scar gives a variable symmetrical and anatomic defect that may not be possible to make inconspicuous of this scar and rebuild good esthetics. In this case report, a five year-old girl was underwent secondary cleft lip repair using straight line technique to correct unfavorable postoperative scar, peaking of Cupid's bow, notching of vermillion and shortened lip on cleft side with simultaneous repairing cleft palatal fistula. After operation, the secondary deformity was much improved, but, long term follow up is needed to evaluate the additional postoperative deformity might be happen during growth.

Purpose: Saddle nose deformity results from lack of support to the nasal dorsum. The integrity of both the cartilaginous or bony portion of the nose is compromised. Cantilever bone graft is the mainstay for correction of saddle nose deformity, but the problems of bone graft are stiffness of the nasal tip and resorption. Thus the authors propose a costochondral cantilever graft, with the bony and cartilaginous portion harvested as one block, using cartilaginous portion as support to the nasal tip. Methods: Between October of 1996 and July of 2005, 8 cases of saddle nose deformity were treated by the same surgeon. All patients had undergone costochondral cantilever graft. Postoperative evaluation included the depression of the nasal dorsum and tip. Comparisons of preoperative and postoperative photographs was done if possible. Results: The mean follow-up period was 5.9 years. The results were excellent aesthetically and there was no complication. Conclusion: The authors' method maximize the benefits of each bone and cartilage graft while minimizing their inherent limitations.

The goal of surgical correction for hallux valgus is to achieve a painless, shoe-wearable, and relatively straight toe with a balanced joint motion that results in aesthetically and functionally satisfactory toe. To date, there has not been a consensus on the ultimate surgical procedure for hallux valgus correction. Unfortunately, such a consensus may be difficult since it is not uncommon to encounter complications after hallux valgus correction. Postoperative soft tissue complications include difficult wound healing, infection, hypertrophy, or pain of the scar, joint stiffness, and tendon or sensory nerve damage. Postoperative bony complications include malunion, nonunion, failure of fixation, failure of angle correction, recurred deformity, osteomyelitis, and failure of balance between the metatarsal heads. Herein, we review common complications after surgical correction of hallux valgus, such as stiff joint, bony complications, recurrence of the deformity, and hallux varus.

Background: We investigated the effectiveness of fibular strut allograft augmentation of proximal humerus fractures to prevent varus deformity in patients over the age of 65 years with insufficient medial support. Methods: We analyzed the clinical and radiological outcomes of locking plate fixation with adjunct fibular strut allograft augmentation in 21 patients with proximal humeral fractures. The inclusion criteria were age (65-year-old or older); presence of severe medial comminution; inadequate medial support; and those who could participate in at least a one year follow-up. The average age was 76.4 years. We analyzed each patient's Constant score, our indicator of clinical outcome. As radiological parameters, we analyzed time-to-bone union; restoration of the medial hinge; difference between the immediately postoperative and the last follow-up humeral neck-shaft angles;; and anatomical reduction status, which was assessed using the Paavolainen method. Results: A successful bone union was achieved in all patients at an average of 11.4 weeks. We found that the average Constant score was 74.2, showing a satisfactory outcome. The average difference in the humeral neck-shaft angles between the immediately postoperative time-point and at the final follow-up was $3.09^{\circ}$. According to the Paavolainen method, the anatomical reduction was rated excellent. The medial hinge was restored in 14 of 21 patients. Although we did not find evidence for osteonecrosis, we found that a single patient had a postoperative complication of screw cut-out. Conclusions: Fibular strut allografting as an adjunct treatment of proximal humeral fractures may reduce varus deformity in patients with severe medial comminution.

Background: Cubitus varus and cubitus valgus deformities are common complications of distal humeral fractures in children. We evaluated the usefulness of supracondylar dome osteotomy as a treatment option for adults with cubitus varus or valgus deformity developed during childhood. Methods: Ten patients who had received supracondylar dome osteotomy and stabilization with plates to treat cubitus varus or valgus deformity between July 2006 and August 2013 were included in this study. Their mean age at the time of surgery was $36.50{\pm}10.22years$. The mean follow-up duration was $54.80{\pm}32.50months$. We evaluated humerus-elbow-wrist angles (HEWA), improvements in the lateral prominence index (LPI) or medial prominence index (MPI), Mayo elbow performance scores (MEPS), and overall results in accordance with the Banerjee criteria. Results: For the six patients with cubitus varus, the mean postoperative HEWA, mean correction angle, and mean improvement in LPI were $9.72^{\circ}{\pm}3.95^{\circ}$, $27.67^{\circ}{\pm}10.75^{\circ}$, and $6.92%{\pm}3.40%$, respectively. For the four patients with cubitus valgus, the mean postoperative HEWA, mean correction angle, and mean improvement in MPI were $14.73^{\circ}{\pm}2.97^{\circ}$, $11.55^{\circ}{\pm}3.26^{\circ}$, and $11.33%{\pm}6.39%$, respectively. There was no significant difference between postoperative and preoperative mean MEPS. The subjective ulnar nerve symptoms were alleviated in all patients. The overall results were excellent in six and good in four patients. Conclusions: This study suggests that supracondylar dome osteotomy with secure fixation using double plates may be useful in correcting cubitus varus or cubitus valgus deformity, yielding good functional outcomes in adults.
