Introduction: Painful plantar callosities under the second and third metatarsal heads are not uncommonly associated with hallux valgus and there have been controversies concerning its treatment modalities. We performed the Weil osteotomy in patients with painful callosities under the second and third metatarsal head associated with hallux valgus, and evaluated the outcome clinically & radiologically. Materials and Methods: From November 2000 through November 2001, out of 51 patients diagnosed with hallux valgus, the Weil osteotomy was performed in 5 women associated with painful callosities under the second and third metatarsal heads. The mean age was 53.4 years (range, 31-66) with a minimum follow-up period of 12 months(range, 12-16). Results: The mean AOFAS lessor metatarso-phalangeal-interphalngeal Scale(LMIS) improved from 61.2 points preoperatively to 88.8 points postopertively. Mean decreases in length of the second and third metatarsal after surgery were 3.2mm and 3mm. Conclusion: We experienced improvement of metatarsalgia in 80% of patients by Weil osteotomy and all patients were symptom-free at last follow-up, suggesting that the Weil osteotomy is an effective procedure in treating painful plantar callosities under the second and third metatarsal heads associated with hallux valgus.

Purpose: The Akin osteotomy which is a closing wedge osteotomy of the proximal phalanx widely used for the correction of hallux valgus has several methods of fixation. we tried to report the effects of the fixation using an absorbable suture material during the Akin osteotomy for the hallux valgus. Materials and Methods: This study was based on 448 cases of 346 patients who were able for follow-up more than 12 months among the patients who had an Akin osteotomy together with the surgery of hallux valgus between March of 2006 and May of 2010. Absorbable suture material had been used in all cases. Radiologically displacement and union of osteotomy site were observed after the surgery, and clinically postoperative complication such as skin irritation, pain and satisfaction were investigated. Results: Radiologically all cases had showed complete union and no case had the loss of an correction due to loss of fixation. Also, any case had no skin irritation due to a knot. Three cases had a medial cortical breakage due to a strong knot, and the initial one case among them had additionally fixed the osteotomy site for four weeks using K-wire, and the remaining two cases had fixed a suture on an articular surface without any fixation of an additional wire. If a medial cortical bone was lost by carrying out an ostectomy due to proximal protrusion of proximal phalanx, three cases could show union through the fixation of suture on an articular surface. Conclusion: This study considers that the fixation of the osteotomy site using an absorbable suture material in an Akin osteotomy was effective method and the advantage of this procedure was unnecessity of the material removal and no skin irritation.

Purpose: The purpose of this study is to evaluate the sequential changes of clinical and radiographic results after proximal chevron osteotomy in patients with moderate to severe hallux valgus. Materials and Methods: Between January 2008 and December 2009, 93 patients (117 feet) were treated with proximal chevron osteotomy and distal soft tissue procedure for symptomatic moderate to severe hallux valgus deformity. The mean age of patients was 51 years (range, 19 to 71) and the mean duration of follow-up was 27.5 months (range, 24 to 35). Clinical results were evaluated using visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) score preoperatively, at 3, 6, and 12 months after surgery, and at the last follow-up. Radiographic parameters including hallux valgus angle, intermetatarsal angle, and sesamoid position were evaluated preoperatively, immediately postoperatively, at 6 weeks, at 3, 6, and 12 months after surgery, and at the last follow-up. Results: VAS and AOFAS score showed significant improvement until 12 months after surgery. Hallux valgus angle and sesamoid position stabilized at 12 months after surgery and intermetatarsal angle stabilized at 6 months after surgery. Conclusion: Clinical and radiographic results were stabilized beyond 12 months after proximal chevron osteotomy in patients with moderate to severe hallux valgus.

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.

Purpose: To treat hallux valgus in old age patients with chevron metatarsal osteotomy and to see the subsequent clinical and radiological outcomes. Materials and Methods: 23 cases of 18 hallux valgus patients of age 60 years or older who received proximal or distal corrective osteotomy from April 2007 to August 2009 and were followed up for at least 1 year were included in the study. The mean age at operation was 65 years (range, 60~81 years), and the mean follow-up period was 2 years and 6 months (range, 1 year~3 years 6 months). Clinical outcome was assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) score, complications, satisfaction rate, as well as measurements and comparison of pre- and postoperative hallux valgus angles, the 1st~2nd intermetatarsal angle, and the position of hallucal medial sesamoid bone. Results: The AOFAS score was improved from preoperative average of 35.1 (range, 13-47) to average 85.1 at last follow-up (range, 75-100). Patients were satisfied about the operation in 21 cases (91.3%). Preoperative hallux valgus angle was $31.7^{\circ}$ on average (range, $19.1^{\circ}-48.9^{\circ}$), and $4.9^{\circ}$ on average at last follow-up (range, $0.3^{\circ}-21.2^{\circ}$). The 1st~2nd intermetatarsal angle was $14.4^{\circ}$on average (range, $8.7^{\circ}-25.7^{\circ}$) and $3.1^{\circ}$ on average at last follow-up (range, $0.6^{\circ}-7.5^{\circ}$). The hallucal medial sesamoid bone position was improved from preoperative average 3.5 (range, 3-4) to postoperative average 1.0 (range, 0-2). Conclusion: Proximal and distal metatarsal osteotomy treatment yielded good clinical and radiological outcomes in old age hallux valgus patients.

Purpose: Recurrence is one of the most common complications after primary correction for hallux valgus deformities. The purpose of this study was to evaluate the usefulness of Scarf osteotomy with axial decompression in the treatment of recurrent hallux valgus. Materials and Methods: From April 2006 to April 2011, 14 cases (12 patients) of recurrent hallux valgus were managed with shortening Scarf osteotomy. Preoperative and postoperative radiographs were reviewed for the measurement of the hallux valgus angle (HVA), intermetatarsal angle (IMA), and the amount of the $1^{st}$ metatarsal shortening. Clinical outcomes including the visual analogue scale (VAS), the AOFAS score, and the range of motion [ROM] of the 1st metatarsophalangeal (MTP) joint were evaluated. Results: The mean HVA decreased from 27.9 degrees to 5.2 and the mean IMA decreased from 12.9 to 3.4. The mean VAS improved from 5.3 to 0.3 and the mean AOFAS score improved from 41 to 90. The mean amount of the 1st metatarsal shortening was 3.4 mm (2-5). The mean ROM of the $1^{st}$ MTP joint improved from 22 degrees (15-35) to 68 (55-75). Conclusion: Scarf osteotomy associated with axial decompression can be a useful revision procedure for the treatment of recurrent hallux valgus deformity.

Occurrence of pseudoaneurysm in the foot and ankle is rare, and is usually caused by traumatic injury or by iatrogenic intervention. Iatrogenic pseudoaneurysms in the foot and ankle have been observed after rearfoot and ankle fusions, ankle arthroscopy, endoscopic and open plantar fasciotomy, tibial osteotomy with limb lengthening, midfoot amputation, and Lapidus procedure. We report on a patient who developed a pseudoaneurysm of the dorsal metatarsal artery following correction of hallux valgus. The patient underwent proximal chevron osteotomy and Akin phalangeal osteotomy. The feeding artery was ligated and the pseudoaneurysm was excised.

Purpose: The purpose of this study is to evaluate the effect of axial shortening metatarsal osteotomy on the treatment of advanced rheumatoid arthritis patients with severe hallux valgus and claw toe deformity of lesser toes which is used for preserving the metatarsophalangeal joint. Materials and Methods: From January 2005 to June 2009, 18 cases of axial shortening metatarsal osteotomy in advanced rheumatoid arthritis were reviewed ; all of them followed up for more than 2 years after surgical procedures and the mean follow up period was 3.4 years. We performed axial shortening Scarf osteotomy and Akin osteotomy for hallux valgus and Weil osteotomy with soft tissue release for claw toe of lesser toes, respectively. We measured preoperative and postoperative hallux valgus angle, each metatarsal shortening length and the range of motion of the metatarsophalangeal joints through radiographic and clinical examination and compared them each other. Clinical results were evaluated by American Orthopedic Foot and Ankle Society (AOFAS) score and subjective satisfaction of the patients. Results: The hallux valgus angle was reduced from the preoperative mean value of 44.8 degree to 9.0 degree postoperatively and the range of motion of the metatarsophalangeal joint of great toe and lesser toes was increased from the mean of 21.7 degree and 11.0 degree preoperatively to 38.0 degree and 32.5 degree, respectively at postoperation. Also, the mean AOFAS score was improved from 26.5 points to 67.4 points. Conclusion: Axial shortening osteotomy is a useful method to correct the deformity and preserve the metatarsophalangeal joint for severe hallux valgus and claw toe deformity in advanced rheumatoid arthritis.

Purpose: The purpose of this study was to retrospectively analyze the clinical and radiologic results of the proximal crescentic osteotomy for moderate to severe hallux valgus deformity. Materials and Methods: Between March 2001 and March 2008, 55 patients (71 feet) who had undergone crescentic osteotomy and distal soft tissue procedure for hallux valgus were followed up for more than one year. The average follow-up period was 15.8 months (12~28 months) and the average age at the time of surgery was 49.8 years (20~69 years). We analyzed the hallux valgus angle (HVA), the first-second intermetatarsal angle (IMA), the length of 1st metatarsal bone and the position of medial sesamoid in preoperative and the last follow-up radiographs. The American Othopeaedic Foot and Ankle Society (AOFAS) score and patient satisfaction were measured by modifying Johnson's method which were used for clinical outcome assessments. Results: The HVA and the IMA were 36.2 and 15.8 degrees preoperatively, and 10.8 and 3.9 degrees at the last follow-up, respectively. The amount of shortening of 1st metatarsal bone averaged $2.3{\pm}1.1$ rum postoperatively. The medial sesamoid position improved from a preoperative average of grade 6.6 to the last follow-up average of grade 1.9. The AOFAS score improved from a preoperative average of 45.3 points to an average 90.6 points at the last follow-up. The patient's satisfaction was completely satisfied in 61 cases (85.9%), satisfied with minor reservations in 6 cases (8.5%), satisfied with major reservations in 2 cases (2.8%), and dissatisfied in 2 cases (2.8%). Conclusion: Proximal crescentic osteotomy produced satisfactory results for moderate to severe hallux valgus deformity.

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.
