Purpose: The authors intended to evaluate the results of symptomatic bunionette treated with a diaphyseal oblique osteotomy. Materials and Methods: Nine patients were followed for more than 1 year after diaphyseal oblique osteotomy for a bunionette deformity with plantar callosity. The mean age was 43 years (23-69 years), and the mean follow-up period was 27 months (12-70 months). As a combined disorder, 7 patients had hallux valgus, for which 3 distal metatarsal oteotomies, 3 proximal osteotomies, and 1 double osteotomy were performed. Clinically, preoperative and postoperative AOFAS MP-IP scale, patient's satisfaction, postoperative complications were analyzed. Radiologically, the 4th intermetatarsal angle and the 5th metatarso-phalangeal angle were analyzed. Results: Clinically, AOFAS MP-IP scale was increased from 59 points preoperatively to 93 points postoperatively, and all patients were satisfied with the results. The plantar callosity had all disappeared at the final follow up. The 4th intermetatarsal angle was decreased from $12.6^{\circ}$ preoperatively to $4.3^{\circ}$ postoperatively, and the 5th metatarsophalangeal angle was decreased from $21.9^{\circ}$ preoperatively to $2.4^{\circ}$ postoperatively. There were no significant postoperative complications. Conclusion: Diaphyseal oblique osteotomy of the 5th metatarsal appears to be safe and satisfactory procedure for the treatment of a symptomatic bunionette with plantar callosity.

Purpose: To report the clinical results of tibio-talo-calcaneal arthrodesis fixed with multiple cannulated screws for the cases of painful ankle and hindfoot arthropathy regardless of any deformity or instability. Materials and Methods: A retrospective analysis was performed upon 10 patients that underwent tibio-talo-calcaneal arthrodesis from October 1999 to May 2006. There were 4 males and 6 females, with an average age of 63 years (43-70). The etioloty of arthrodesis included 5 osteoarthritis, 2 Charcot joints, 1 rheumatoid arthritis, 1 Tbc arthritis and 1 residual poliomyelitis. Chief complaints were pain in 9 cases and instability in 1 case. Three patients had combined severe varus deformity. Tibio-talo-calcaneal arthrodesis using multiple cannulated screws was performed by transfibular approach for all cases and short leg cast was applied for 12 weeks postoperatively. Results: The average follow-up period was 16.5 months (12-26 months). VAS pain score was average 8.2 (7-10) and modified AOFAS score was average 25 (8-40, total 86) preoperatively. At final follow-up, VAS score was average 1.0 (0-3) and AOFAS score improved to average 66 (58-75). There were 4 complications: 2 nonunion, 1 tibia stress fracture and 1 malunion. Seven of 8 patients were satisfied with the results at final follow-up. Conclusion: Fixation with multiple cannulated screws for tibio-talo-calcaneal arthrodesis through transfibular approach is a recommendable surgical option.

Purpose: We conducted this study to examine the clinical results of the proximal metatarsal wedge osteotomy using a single screw fixation and the distal soft tissue procedure in patients with moderate to severe hallux valgus deformity. Materials and Methods: Between February 2002 and February 2004, we performed these procedures on 12 patients (15 cases). The 6 cases of all patients had mild to moderate instability in the first MTC (metatarsocuneiform) joint. We estimated the clinical outcomes, the radiological findings and complications. Results: AOFAS score was improved from preoperative 41.5 points to 87.7 points lastly on average. The mean correction angle of HVA and IMA was $23.8^{\circ}$ and $6.6^{\circ}$, respectively. The mean position of tibial sesamoid was 2.67 before surgery and 0.87 after surgery. The mean shortening of the first metatarsal bone was 3.07 mm after surgery. There was no pain and complications on the first MTC joint except the breakage of screw in one case and instability of the first MTC joint was improved postoperatively. Conclusion: We obtained good clinical and radiographic outcomes in our series. So, proximal metatarsal wedge osteotomy using a single screw fixation and distal soft tissue procedure seems one of the good surgical treatments for moderate hallux valgus deformity.

Purpose: We evaluate the results of subtalar arthroereisis with $Kalix^{(R)}$ implant (Newdeal, Lyon, France) that were performed in painful flatfoot deformity. Materials and Methods: We performed the subtalar arthroereisis on 16 feet of children symptomatic flexible flat feet after more than 6 months of conservative treatment. Average age was 11 years (8-14 years) old. We checked the functional status with AOFAS functional score in pre-operatively and at final follow-up. Radiologically, we took weight bearing anterior to posterior and lateral view of the feet, and measured the talo-$1^{st}$ metatarsal angle, calcaneal pitch angle, cuboid-surface height. Finally, we asked to patient's parents for satisfaction of the surgery. Results: Mean follow up period was 34.1 months. Average AOFAS score improved from preoperatively 71.9 to postoperatively 91.3. Only one patient has subtalar pain. Average lateral $1^{st}$ metatarsal angle reduced from $-18.2^{\circ}$ preoperatively to $-4.6^{\circ}$ at final follow-up. Average anterior to posterior $1^{st}$ metatarsal angle was reduced from $18.9^{\circ}$ preoperatively to $6.5^{\circ}$ at final follow-up. Average calcaneal pitch angle was increased from $8.6^{\circ}$ preoperatively to $12.6^{\circ}$ at final follow-up. Average cuoboid-surface height was improved from 12.1 mm preoperatively to 16.0 mm at final follow-up. All patients had excellent or good satisfaction. Conclusions: Subtalar arthroereisis with $Kalix^{(R)}$ implant is a viable surgical alternative for painful flatfoot deformity of children.

Purpose: End-stage ankle arthritis is frequently combined with ankle-hindfoot deformity or ankle instability and therefore additional surgical procedures are often required when performing total ankle arthroplasty. We report the short term clinical and radiographic results of the total ankle arthroplasty with/without the combined adjunctive surgical procedures. Materials and Methods: The study is based on the 17 ankles (16 patients) of end-stage ankle arthritis that were treated with $HINTEGRA^{(R)}$ Total ankle prosthesis (Newdeal, Lyons, France) total ankle arthroplasty (TAA) from 2004 to 2007 with at least 12 months follow-up. The combined adjunctive procedures as well as the VAS pain score, AOFAS score, radiographic measurements and patient satisfactions were evaluated. Results: Average follow-up period was 29 months (13${\sim}$55 months), and the age was average 62 years (39${\sim}$75 years) old. Among total of 17 ankles, varus deformity and lateral ankle instability were found in 4 cases and 3 cases respectively. Twenty additional procedures such as Achilles triple hemisection (9), calcaneal displacement osteotomy (4) and lateral ankle ligament reconstruction (3) were performed in adjunct to TAA in 13 ankles. VAS pain score improved from preoperative average 8.4 (7${\sim}$10) to 2.0 (0${\sim}$5) and the AOFAS functional score improved from 41.8 points (13${\sim}$71 points) to 90.6 (77${\sim}$100 points) at final follow-up. Ninety-four percent of the patients were satisfied with the surgery. Conclusion: We confirmed that many adjunctive combined surgical procedures are often necessary in addressing the end-stage ankle arthritis (74%) with total ankle arthroplasty. We also achieved quite good clinical and radiographic short term results, although the long term follow-up study with larger number of cases are needed in the future.

Purpose: The purpose of this study was to evaluate the radiographic results and complications after the proximal dome osteotomy for hallux valgus. Material and Methods: 127 cases of clinically moderate to severe hallux valgus from October 1994 to September 1997 were included in this study. All had been surgically corrected with proximal dome osteotomy, bunionectomy, and distal soft tissue release. We compared the hallux valgus angle(HVA) and intermetatarsal angle(IMA) at preoperative, postoperative 3 weeks, postoperative 6 weeks, and postoperative 3 months. Also we reviewed the postoperative com plications. Result: The HVA averaged $34.1^{\circ}$ at preoperative, $4.3^{\circ}$ at 3 weeks after operation, $8.1^{\circ}$ at 6 weeks after operation, and $10.2^{\circ}$ at 3 months after operation. The lMA averaged $14.6^{\circ}$ at preoperative, $5.1^{\circ}$ at 3 weeks after operation, $5.6^{\circ}$ at 6 weeks after operation, and $7.3^{\circ}$ at 3 months after operation. We experienced 7 cases of malunion, 5 cases of limitation of motin at the first metatarso-phalangeal joint, 3 cases of hallux varus deformity, 2 cases of delayed union. Conclusion: Proximal dome osteotomy for moderate to severe hallux valgus deformity was considered as one of the effective treatment methods. And we try to avoid limitation of motion at the first metatarso-phalangeal joint after operation.

목 적: 후족부의 병리학적 상태의 치료와 평가를 위해서는 관상면에서 종골과 경골이 연관된 배열상태의 정확한 평가가 필수적이다. 이전의 방사선학적 검사인 발과 발목의 전후방향, 측방향, 사방향 촬영과 종골 축방향 촬영 등의 X-선 촬영상은 관상면에서 종골과 경골이 연관된 배열상태를 증명하지 못했다. 이에 본 연구에서는 후족부 관상면 배열영상(hindfoot coronal alignment view)을 새롭게 소개하고자 한다. 검사방법 : 1) 양쪽 발을 지탱할 수 있는 방사선투과성의 스탠드형 보조기구를 제작한다. 2) 양측 발은 weight-bearing position이 되게 한다. 3) 각각의 발의 위치는 발의 종축이 보조기구 판과 수직이 되도록 자세를 유지한다. 4) silhouette tracing: 발뒷꿈치 outline과 둘째 발가락이 일직선상으로 지나도록 위치시킨다. 5) 중심 X-선: 발바닥 쪽을 향해 약 $15{\sim}20^{\circ}의 각도로 종골의 뒷쪽을 향해 입사한다. 결 과 : 1) 경골 축과 종골의 내측, 외측 결절의 영상이 함께 표출된다. 2) 종골이 회전되지 않아야 한다. 3) 거퇴관절강(talotibial joint space)이 함께 나타나야 한다. 결 론: CT나 MRI 영상에서도 관상면에서 후족부의 배열상태를 증명할 수 있지만, 환자의 체중이 주어지지 않기 때문에 발의 임상적인 증상을 보여주기에는 충분하지 못했다. 하지만 후족부 관상면 배열영상은 후족부의 inversion, eversion의 자세변화를 보여주고, 경골 원위부와 종골의 varus, valgus deformity의 치료를 위한 평가 자료로 좋은 검사방법이며, 비교적 자연스럽고 편안한 자세로 환자에게 큰 도움을 줄 것으로 사료된다.

Purpose: A retrospective review of the radiographs of the proximal metatarsal osteotomy and distal soft tissue procedure for hallux valgus, evaluating the correction of the tibial sesamoid, was undertaken. We evaluated the correlation between the reduction of the tibial sesamoid and the clinical outcomes. Materials and Methods: 17 patients (23 cases) with moderate to severe hallux valgus deformity underwent the proximal metatarsal osteotomy and distal soft tissue procedure. The preoperative and last follow-up radiographs were reviewed according to the tibial sesamoid grade classification recommended by the Research Committee of the American Orthopedic Foot and Ankle Society (AOFAS). We divided them into two groups according to the reduction of the tibial sesamoid. We anaylyzed the clinical outcomes in each group according to Mayo Clinic Forefoot Scoring System (FFSS). Results: In all of the patients, the preoperative tibial sesamoid position were grade 2 or greater. At the last follow-up, 52% (n=12) were grade 1 or less (Group I) and 48% (n=11) were grade 2 or greater (Group II). In group I, the forefoot score was improved from preoperative mean value of 32.0 points to final follow-up value of 66.3 points. In group II, the forefoot score was improved from preoperative mean value of 31.7 points to final follow-up value of 65.9 points. There was no statistical significance between postoperative, average scores in group I and II (p>0.05). Conclusion: The position of the tibial sesamoid was corrected insufficiently in almost half of all cases. In view of clinical outcomes, there was no significant difference between the corrected group and the other group.

Purpose: The purpose of this study is to evaluate the clinical and radiographic results of symptomatic bunionette treated with a diaphyseal oblique osteotomy. Materials and Methods: We retrospectively reviewed 12 feet of nine patients diagnosed as symptomatic bunionette and treated with diaphyseal oblique osteotomy. All patients were female and the average age at the time of surgery was 48 years. We checked the foot standing anteroposterior, oblique, and lateral images pre- and post-operatively. We measured the fourth intermetatarsal angle and fifth metatarsophalangeal angle and evaluated the clinical results using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal (MTP-IP) scale preoperatively and six months postoperatively. Results: Of the nine patients, hallux valgus was combined with symptomatic bunionette in seven feet of five patients. In all of our cases, the average AOFAS lesser MTP-IP scale showed improvement after surgery. Painful callosity around the fifth metatarsophalangeal joint disappeared after surgery in all of our cases. The fourth intermetatarsal angle improved from $12.7^{\circ}$ to $3.1^{\circ}$ and the fifth metatarsophalangeal angle improved from $16.6^{\circ}$ to $2.3^{\circ}$. Conclusion: Diaphyseal oblique osteotomy of the fifth metatarsal appears to be a safe and satisfactory surgical procedure for treatment of symptomatic bunionette.

Because traumatic tissue damage on hands and feet often lead to loss of function, permanent deformity, prompt and adequate reconstruction is essential. For children, future growth, as well as function and esthetics, must be taken into account. Several techniques have been employed to reconstruct hand and foot dorsum defects of children. However, skin graft and muscle free flap with skin graft cannot prevent contracture and will interfere with normal growth. Fasciocutaneous free flap reduces contracture and enables early physical therapy, decreasing the need for additional surgical intervention. Parascapular flap is particularly suitable because it has reliable pedicle and is relatively thin. There is little functional loss in the donor site, and also simultaneous extensor tendon reconstruction of hand and foot is possible. The disadvantage of this technique is that postoperative defatting is needed to adjust volume. Our department has achieved satisfactory results using this approach, and would like to report 13 cases of hand and foot reconstruction using parascapular flap in patients under the age of 15 (from March, 1998 to May, 2003).
