Purpose: The purpose of this study was to figure out the appropriate and systemic insurance charge for the hallux valgus operations. Materials and Methods: 5 Hospitals for hallux valgus operations were analyzed how they have been charging the national health insurance corporation for their operation fees and how to use the estimated guide and authoritive interpretation through the guide book of health insurance medical treatment grant expense and the guide book of Health insurance medical treatment. Results: There are nothing for guiding principle of hallux valgus operations in both books but a guide of Mcbride operation which is approved 'JA-93-KA and JA-31' for operation fee. So majority of hospitals have charged operation fee depending on their own interpretations they like. According to the guide books, there was a authoritive interpretation that simultaneous operation of osteotomy and tendon transfer for cerebral palsy and flat foot can be eatimated as 'osteotomy+JA-93-NA'. Conclusion: Distal soft tissue procedure should be approved as 'JA-93-NAx100%+JA-31x50%' according to the the estimated guide and authoritive interpretation if transected adductor hllucis is transfered to first metatarsal head. So distal chevron osteotomy could be 'JA-30-1-RAx100%+JA-31x50%', proximal metatarsal osteotomy could be 'JA- 93-NAx100%+JA-31-50%+JA-30-1-RAx50%', first metatarsocuneiform joint arthrodesis could be 'JA-93-NAx100%+ JA-31x50%+JA-73-RAx50%'.

Purpose: Patellar dislocations have a range of causes. This study examined the results of treatment aimed at balancing soft tissues around the patella. Materials and Methods: Thirty-two patellar dislocations in 28 patients (21 females and seven males) were examined. The mean patient age at the time of surgery was 11.5 years, and the mean follow-up period was 4.6 years. Dislocations were 19 chronic, six habitual, six congenital, and one acute. Soft tissue balancing surgery included lateral capsular release, medial capsular plication, and inferolateral transfer of the vastus medialis obliquus. Medial transfer of the patellar tendon, partial strip of the rectus femoris and patella tendon, and distal femoral osteotomy were also performed selectively. The preoperative Q angle, femoral anteversion angle, tibial external rotation angle, tibial tubercle-trochlear groove distance (TT-TG distance), mechanical femoral-tibial angle, and femoral trochlear dysplasia according to Dejour were measured, and the pre- and postoperative Lysholm-Tegner scores were used to analyze the clinical results. Results: The mean preoperative Q angle, TT-TG distance, femoral anteversion angle, tibial external rotation angle, mechanical femoraltibia angle, and Lysholm-Tegner score were 9.3°, 15.5 mm, 25.6°, 30.4°, 3.0°, and 75.8, respectively. Eleven patients had systemic ligament laxity with a Beighton score of five or more. Twenty-two patients had femoral trochlear dysplasia: four type A (3 patients), 16 type B (15 patients), one type C (1 patient), and four type D (3 patients). Of the 32 cases, 28 were corrected successfully by the first operation. Of four cases of postoperative subluxation, three were corrected by the second operation, and one of them was corrected after a third operation. The last patient is currently being followed-up. The mean Lysholm-Tegner score improved to 85.6 after the operation. Conclusion: Correcting all the causes of patella dislocation simultaneously is difficult. Nevertheless, satisfactory outcomes were obtained with soft tissue balancing surgery around the patella and a corrective osteotomy for an abnormal mechanical axis of the femur-tibia and torsion.

Purpose : Plantar surfaces, calcaneal area, and region of Achilles insertion, which are extremely related with weight-bearing area and shoes application, must be reconstructed with glabrous and strong fibrous skin. Numerous methods of reconstructing defects of these regions have been advocated, but the transfer of similar local tissue as a cutaneous flap with preservation of sensory potential would best serve the functional needs of the weight-bearing and non-weight-bearing surfaces of this region. Therefore it is recommended to use the limited skin of medial surface of foot that is similar to plantar region and non-weight-bearing area. In this paper we performed the medial plantar flap transfered as a fasciocutaneous island as one alterative for moderate-sized defects of the plantar forefoot, plantar heel, and area around the ankle in 25 cases and report the result, availability and problem of medial plantar flap. Materials and methods : We performed proximally based medial plantar flap in 22 cases and reverse flow island flap in 3 cases. Average age was $36.5(4{\sim}70)$ years and female was 3 cases. The causes of soft tissue defect were crushing injury on foot 4 cases, small bony exposure at lower leg 1 case, posterior heel defect with exposure of calcaneus 8 cases, severe sore at heel 2 cases, skin necrosis after trauma on posterior foot 4 cases, and defect on insertion area of Achilles tendon 6cases. Average follow up duration was 1.8(7 months-9.5 years) years. Results: Medial plantar flaps was successful in 22 patients. 18 patients preserved cutaneous branches of medial plantar nerve had sensation on transfered flap but diminished sensation or dysesthesia. At the follow up, we found there were no skin ulceration, recurrence of defect or skin breakdown in all 18 patients. But there was one case which occurred skin ulceration postoperatively among another 4 cases not contained medial plantar nerve. At the last follow up, all patients complained diminished sensation and paresthesia at medial plantar area distally to donor site, expecially with 4 patients having severe pain and discomfort during long-time walking. Conclusion : Medial plantar island flap based on medial plantar neurovascualr pedicle have low failure rate with strong fibrous skin and preserve sensibility of flap, so that it is useful method to reconstruct the skin and soft tissue defect of foot. But it should be emphasized that there are some complications such like pain and paresthesia by neuropraxia or injury of medial plantar nerve at more distal area than donor site. We may consider that medial plantar flap have limited flap size and small arc of rotation, and require skin graft closure of the donor defect and must chose this flap deliberately.

Purpose: To analyze the clinical and radiologic results of the shoulder arthrodesis in brachial plexus injury patients with flail upper extremity. Material and Method: From Aug 1978 to April 2008, 29 shoulders in 29 patients with brachial plexus injury with shoulder fusion, we evaluated 20 shoulders in 20 patients, more than 1 year follow up. The average follow-up period was 6.45years (range: 1year~24years). There were 13 men and 7 women, and the mean age at the time of trauma was 32.0years(2~65 years). The type of injury was a motorcycle accident in 11 patients, in car accident in 5, pedestrian accident in 3, and fall from a height in 1. The lesion of injury was root and trunk in 1 patient, trunk and cord in 1, trunk in 18. Surgery was performed on the whole arm type paralysis in 12 patients, lower arm type paralysis in 8 patients. The preoperative visual analog scale score was 8.7(7~10). When the trapezius and serratus anterior muscle were in function, operation was performed. 18 patients were processed to the additional operation. Gracilis free flap in 6 patients, neurotization in 3, Steindler flexor plasty in 6, and tendon transfer in 3 were performed. Fixation was conducted with cancellous screws in 13 patients, Knoles pins in 5, and cancellous screws and Knoles pins in 2. The position of the arthrodesis at operation was $28.5^{\circ}$($20~45^{\circ}$) in abduction, $30.3^{\circ}$($20~45^{\circ}$) in flexion, and $30.8^{\circ}$($20~40^{\circ}$) in internal rotation. Result: The follow up visual analog scale score was 3.4(0~7). Postoperatively, shoulder spica cast was applied for 15.3weeks(8-20weeks). The median time to bony union was 17.7weeks(9~28weeks). Average range of motion was $32.0^{\circ}$($15~40^{\circ}$) of abduction, $24.0^{\circ}$($10~40^{\circ}$) of flexion, and $18.5^{\circ}$($10~30^{\circ}$)of internal rotation. Conclusion: The shoulder fusion in brachial plexus injury patients is one of the good methods to relieve pain, improve the function and stabilize the flail shoulder joint.

Purpose: This study evaluated the results of surgical treatment for residual or recurrent deformity after the conservative treatment of idiopathic clubfoot. Materials and Methods: Fifty-one cases (32 patients), who were followed up to skeletal maturity, were reviewed retrospectively. The mean age at the last follow-up was 18.7 years. The surgical options included selective or comprehensive soft tissue release, tendon lengthening and transfer, and various types of osteotomy. The radiology measurements included the talocalcaneal angle and talo-first metatarsal angle in the anteroposterior (AP) view, and the talocalcaneal angle and calcaneal pitch in the lateral view. The radiology measurements were compared with the normal values for adults. The clinical evaluations were made using the ankle-hindfoot score and the midfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS): excellent (>85), good (71-85), pair (56-70), and poor (<56). Results: At the last follow-up, the percentages of the 51 cases, whose parameter values fell within the normal ranges were as follows: in the AP view, 41.2% (talocalcaneal angle); and 90.2% (talo-first metatarsal angle). In the lateral view, the percentage was 84.3% (talocalcaneal angle). For the calcaneal pitch, the percentages were 61%. The mean AOFAS score was 88.1±10.7 on the ankle-hindfoot score and 86.7±11.5 on the midfoot score. Conclusion: The long-term outcome of patients with idiopathic clubfoot, who underwent surgical treatment after conservative treatment, was found to be 43%-90% of the normal range of radiographic indices. Clinically, the mean AOFAS scores were "excellent". Therefore, a satisfactory result can be obtained by analyzing the elements of deformity more accurately and then using the selective operation method, even if the non-surgical correction method fails.
