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: Achilles tendon rupture has become more common in the recent years. As suture with foreign material has been blamed for impaired healing, better results should be expected from the use of autogenous material such as plantaris tendon. We have evaluated the surgical results of end-to-end anastomosis using the plantaris tendon as suture material. Materials and Methods: Between Jan 1997 and Jan 2002, the 60 patients were included this study during one year follow-up. We performed the operations with end-to-end suture technique using modified Lynn's method. The plantaris tendon has been used as a autogenous suture material and can be utilized in the end-to-end anastomosis of ruptured Achilles tendon with modifed Bunnel suture technique. We used a clinical scoring system reported by Leppilahti to evaluate the results. Results: The overall results were excellent in thirty eight(63.3%), good in sixteen(26.6%), fair in five(8.3%) cases, and poor in only one (1.6%) case. Fifty four cases(90%) had the score more than good. We had no deep infection, rerupture, deep vein thrombosis, and skin necrosis as major complication. In just 2 cases, although there were superficial skin infection, the wounds did not proceed necrosis due to using antibiotics. Conclusion: End-to-end anastomosis using the plantaris tendon as suture material was good treatment option that had low infection rate and no foreign body reaction because of using autogenous material, and therefore we can get rapid healing of ruptured tendon due to early ragne of motion and accerlerated rehabilitation.

Last week, after our receiving online journal regarding Journal of the Korean Association of Oral and Maxillofacial Surgeons, we found a recently published original article by Alawode et al., entitled "A comparative study of immediate wound healing complications following cleft lip repair using either absorbable or non-absorbable skin sutures". Although this clinical article was well written and provided a great deal of information regarding the suture materials in the cleft lip repair, I would like to add a few additional comments based on the importance of skin suture during cheiloplasties in the primary cleft lip or secondary revision patients with representative figures.

Purpose: The purpose of this study was to document the results of fixation with ethibond suture in akin osteotomy and its advantages. Materials and Methods: From May 2001 to January 2004, Akin osteotomy was performed in 218 patients. We reviewed 110 patients (114 feet) who were possible radiographic evaluation more than 6 months after operation. 110 feet had hallux valgus and 4 feet had hallux valgus interphalangeus. 105 patients were female and 5 were male. The average age was 43.8 years old (18 to 68 years old). The average follow up was 9 months (6 to 23 months). After performing the Akin osteotomy at 7 mm from the proximal articular surface of the proximal phalanx, one hole is made on either side of the osteotomy site with a K-wire. The passer was passed through the both holes and the ethibond was passed. And then, the ethibond was tied tightly. 2 sutures in 66 feet and 1 suture in 48 feet were made. Radiographic bone union at 6 months follow up was regarded as success and loss of the reduction, nonunion was regarded as failed. Results: In the radiographic evaluation, bony union were made at 6 months follow up in all feet. There was no difference between 2 sutures and 1 suture, and the knots were removed in 3 feet because of skin irritation. Conclusion: The fixation of the osteotomy site using suture material was an effective method in Akin osteotomy. The advantage of this procedure was unnecessity of the material removal.

Purpose: The purpose of this study was to analyze the clinical results of medial horizontal suture fixation of Akin osteotomy in hallux valgus and present its advantages. Materials and Methods: This study was based on 48 cases of 35 patients with Akin osteotomy, who underwent surgery of hallux valgus between December 2014 and July 2015, and with at least 12 months of follow-up. The mean age of patients was 46.9 years (range, 16~71 years). The mean follow-up duration was 15.9 months (range, 12~18 months). Clinical evaluations included pain visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS hallux metatarsophalangeal interphalangeal scale) score, and satisfaction score. Weightbearing anteroposterior radiographs were taken to measure the distal articular set angle (DASA) of the hallux. Radiographic bone union at 6 months follow-up was regarded as a success, while a loss of reduction and nonunion was regarded as a failure. Results: The mean pre- and postoperative pain VAS scores were 4.27 and 1.67, respectively (p<0.05). The mean AOFAS score improved from 59.7 to 80.5 (p<0.05). The DASA was improved from 8.15 to -2.57 (p<0.05). There was no case of skin irritation, cortical breakage, inflammation from the knot, and infection. All patients showed union without fixation failure. Conclusion: The clinical and radiological evaluations in this study demonstrate reliable results without complication. The medial horizontal suture fixation of the Akin osteotomy was effective, and the advantage of this procedure was unnecessity of the material removal, preservation of the joint, and no skin irritation.

Purpose: When medial protrusion in the base of proximal phalanx is severe from removing metatarsal bunion during the hallux valgus surgery, it could lead to skin irritation and medial pain after the surgery. The purpose of this paper was to report our clinical and radiographic results with transarticular fixation of Akin osteotomy for the treatment of patients with hallux valgus after resection of the medial protrusion of base of the proximal phalanx. Materials and Methods: Our study is subject to 34 cases of 30 patients who went through proximal phalanx medial corticectomy among patients undergone both hallux valgus surgery and Akin osteotomy at our institution from March 2006 to March 2012. In all cases, we used absorbable suture material through the articular surface for Akin osteotomy after resection of the medial protrusion in proximal phalanx. Radiographs were reviewed to assess the union and displacement of osteotomy site at the time of postoperative 6 months. The clinical results were assessed by using AOFAS score and complication such as skin irritation and pain. Results: AOFAS score was improved from average 44 points(36-58), before operation and average 87 points(74-96), 12 months after operation. In two cases, partial union was suspected in radiological perspective, however, complete union on the osteotomy site was observed in all cases, 12 months after the operation. No patients was dissatisfied with pain, joint discomfort, skin irritation and inflammation from the knot. Conclusion: When medial protrusion in the base of proximal phalanx is severe from removing metatarsal bunion during the hallux valgus surgery, We have good results by transarticular fixation of Akin osteotomy using absorbable suture material.

Biological safety, physico-chemical and microbiological experiments were carried out in order to study the possibility of radiation sterilization on medical products, such as polyethylene and polystyrene bottles, gauze sponges and surgical silk suture. Results are as follows: 1. Biological test on plastic samples as to acute systemic toxicity, eye irritation, skin irritation, pyrogen, haemolysis showed satisfactory results. But physico-chemically, the oxidizable matter, nonvolatile residues, residue on ignition seemed to be increased slightly in irradiated samples, though the experimental results were within the range of U.S.P. 19, N.F. and K.P. III. 2. After irradiation, both plastic and gauze sponges showed considerable decrease in pH. 3. Most medical products were sterilized by 1.5 Mard. For the sterilization of the suigical silk suture, 4.5 Mrad is required dul to its radiation resistant micro-organisms. 4. Biologically, total dose of 2.5 Mrad was safe enough to sterilize the medical products, and physico-chemically the results are acceptable according to U.S.P. 19 and K.P. III. However, better results may be expected when the quality of material and additives are improved.

Purpose: The aim of our study was to present an abdominal wall closure technique using barbed suture $V-Loc^{TM}$ 90 after single incision laparoscopic appendectomy (SILA) and to compare perioperative outcomes with conventional layer by layer abdominal wall closure after SILA. Methods: From March 2014 to July 2016, a retrospective case-control study was conducted for a total of 269 consecutive patients who underwent SILA. According to abdominal wall closure methods, 129 patients were classified into the V-Loc closure group and 140 patients were assigned into the conventional layer by layer closure group. In the V-Loc group, abdominal wall closure was performed from the fascia to the skin with a single thread of unidirectional absorbable barbed suture $V-Loc^{TM}$ 90 2-0 using continuous running suture and reverse overlapping reinforced running technique. Subcutaneous closure and subcuticular suture were performed with the remaining portion of V-Loc. Results: The V-Loc closure group showed shorter total operation time ($40.0{\pm}15.4min$ vs. $44.9{\pm}16.3min$, p=0.013) and abdominal wall cusing continuous running suture and reverse overlapping reinforced running technique. Subcutaneous closure and subcuticular suture were performed with the remaining portion of V-Loc. Results: The V-Loc closure group showed shorter total operation time losure time ($5.5{\pm}0.9min$ vs. $6.5{\pm}0.8min$, p<0.001). Postoperative incision length was significantly shorter in the V-Loc closure group ($1.1{\pm}0.3cm$ vs. $1.8{\pm}0.4cm$, p<0.001). Postoperative wound pain, time to resume diet, postoperative hospital stay, complications including surgical site infection, or mean patient satisfaction score at one month after hospital discharge was not significantly different between the two groups. Conclusion: In conclusion, unidirectional knotless barbed suture is a safe alternative method for abdominal wall closure after SILA. It can save time while providing comparable cosmesis.

Background The most common cause of skin graft failure is the collection of blood or serous fluid underneath the graft. In our study, we describe the use of silicone tube for tie-over dressing to secure the skin graft margins with the aim of decreasing loss of the skin graft, particularly in grafting of deep wounds. Methods Between March 2008 and July 2011, we used this technique in 17 patients with skin defects with depths ranging from 3.5 to 8 mm (mean, 5.5 mm). First, the skin graft was sutured with 3/0 silk suture material from its corners. Then, a silicone round drain tube was sutured with 3/0 absorbable polyglactin 910 over the margins of the graft. Finally, long silk threads were tied over the bolus dressing, and the tie-over dressing was completed in the usual fashion. Results The mean follow-up was 7 months (range, 2-10 months) in the outpatient clinic. Graft loss on the graft margins due to hematoma or seroma was not developed. The results of adhesion between the graft and wound bed peripherally was excellent. Conclusions In our study, we suggest that use of a silicone tube for additional pressure on the edges of skin grafts in case of reconstruction of deep skin defects.

Purpose: Microfat graft is a common procedure for correcting tear trough deformity and dark circle. Because the tissue in this area is very thin, the grafted fat, sometimes, induces palpable lumps and uneven skin contour. When it happens, the surgical removal of the grafted fat is often needed. The authors made attempt of transconjunctival approach for removal, and this made infraorbital fat repositioning possible at the same time. Methods: 15 female patients with history of microfat graft on lower eyelid, got operation for the grafted fat removal with transconjunctival approach from April of 2009 to July of 2010. The dissection was performed in accordance with infraorbital fat repositioning surgery. Through the transconjunctival incision, knotted fat on orbital septum and orbicularis oculi muscle was removed without damage on skin. After grafted fat removal, subperiosteal space was made 1~2 mm below the inferior orbital rim by elevating periosteum. With preserving orbital septum, infraorbital fat was repositioned and anchored to subperiosteal space. Finally, transconjunctival incision was closed with absorbable suture material. Results: 14 patients in the study showed satisfactory results. The problems like uneven skin contour and knotted fat mass, were all solved. In only one patient, incomplete correction was observed, as bulging on her right lower eyelid still remained. One patient complained of transient numbness on lower eyelid, but there was no specific complication other than this. Conclusion: The authors attempted the method of transconjunctival approach to remove former grafted fat in lower eyelid and reposition infraorbital fat simultaneously. Since the study brought great results, the method would be helpful to patients and surgeons.
