Effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions / 中国修复重建外科杂志

Objective: To investigate the effectiveness of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions. Methods: Between January 2012 and December 2016, 36 patients (36 feet) with ankle diseases underwent tibio-talo-calcaneal arthrodesis with parallel double thread headless compression screws via minimal anterior and lateral oblique incisions. There were 14 males and 22 females with an average age of 53.8 years (range, 18-76 years). There were 19 cases of left feet and 17 cases of right feet. There were 21 cases of talar necrosis, 7 cases of post-traumatic arthritis, 3 cases of rheumatoid arthritis, 2 cases of tuberculosis infection (inactive), 1 case of talar absence, 1 case of Charcot’s disease, and 1 case of pigmented villonodular synovitis of ankle and subtalar joints. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were 53.7±2.5 and 5.9±0.2, respectively. The operation time was recorded and the wound healing and complications were observed. The bone healing was assessed by X-ray film and CT scanning. The function and pain of joint were evaluated by AOFAS and VAS scores. Results: The mean operation time was 49.8 minutes (range, 33-82 minutes). Incision infection occurred in 1 patient (2.8%) at 3 weeks after operation, and recovered after debridement. The other incisions healed by first intention without complications. Thirty-five patients were followed up with an average of 18.5 months (range, 12-29 months). Imaging examination showed fusion of the ankle and subtalar joints with an average fusion time of 10.9 weeks (range, 8-15 weeks). After 1 year, the AOFAS score (84.7±0.6) and VAS score (0.3±0.1) were significantly higher than preoperative scores ( t=12.596, P=0.000; t=30.393, P=0.000). Conclusion: It is an effective surgical method of tibio-talo-calcaneal arthrodesis with full thread headless compression screws via combined minimal incisions for end-stage ankle disease because of the less complications incidence and the higher postoperative fusion rate.

Comparison between a novel Super-Minimal Incision Kidney Transplantation and conventional Gibson incision kidney transplantation / 中华器官移植杂志

Objective To evaluate the safety of super-minimal incision kidney transplantation (SMIKT).Methods We included the clinical data and outcomes of 40 cases of SMIKT and 56 cases of conventional Gibson incision kidney transplantation (CIKT),and compared the operation time,post operative pain,analgesic requirements,1 month renal function and 1 month Vancouver scar scale between the two groups.Results As compared with CIKT,operation time was significantly shortened (100 ± 10 versus 127.5 ± 34.3 min,P =0.044),incision length was significantly shortened (5.2 ± 0.2 versus 13.0 ± 2.0 cm,P＜0.001),and post-operative pain at day 1 was significantly reduced in SMIKT (1.31 ± 1.15 versus 4.02 ± 1.83,P =0.004).However,there was no significant difference in post-operative pain at day 2 and day 3 between CIKT and SMIKT.SMIKT required less analgesic medications than CIKT (3.13 ± 1.74 versus 11.69 ± 2.89,P =0.002).No significant difference in 1 month renal function was observed between two groups.SMIKT had fewer Vancouver scar scale score than CIKT (6.50 ± 0.58 versus 8.67 ± 0.58,P =0.004).Conclusion SMIKT is a safe novel surgery,which can significantly reduce operation time,post-operative pain,had fewer analgesic requirements and better 1-month cosmetic effect.

Minimal abdominal incisions / Incisões abdominais mínimas

ABSTRACT Minimally invasive procedures aim to resolve the disease with minimal trauma to the body, resulting in a rapid return to activities and in reductions of infection, complications, costs and pain. Minimally incised laparotomy, sometimes referred to as minilaparotomy, is an example of such minimally invasive procedures. The aim of this study is to demonstrate the feasibility and utility of laparotomy with minimal incision based on the literature and exemplifying with a case. The case in question describes reconstruction of the intestinal transit with the use of this incision. Male, young, HIV-positive patient in a late postoperative of ileotiflectomy, terminal ileostomy and closing of the ascending colon by an acute perforating abdomen, due to ileocolonic tuberculosis. The barium enema showed a proximal stump of the right colon near the ileostomy. The access to the cavity was made through the orifice resulting from the release of the stoma, with a lateral-lateral ileo-colonic anastomosis with a 25 mm circular stapler and manual closure of the ileal stump. These surgeries require their own tactics, such as rigor in the lysis of adhesions, tissue traction, and hemostasis, in addition to requiring surgeon dexterity - but without the need for investments in technology; moreover, the learning curve is reported as being lower than that for videolaparoscopy. Laparotomy with minimal incision should be considered as a valid and viable option in the treatment of surgical conditions.

RESUMO Procedimentos minimamente invasivos visam resolver a doença com o mínimo de trauma ao organismo, resultando em retorno rápido às atividades, reduções nas infecções, complicações, custos e na dor. A laparotomia com incisão mínima, algumas vezes referida como minilaparotomia, é um exemplo desses procedimentos minimamente invasivos. O objetivo deste trabalho é demonstrar a viabilidade e utilidade das laparotomias com incisão mínima com base na literatura e exemplificando com um caso. O caso descreve uma reconstrução de trânsito intestinal com o uso desta incisão. Paciente masculino, jovem, HIV-positivo, pós-operatório tardio de ileotiflectomia, ileostomia terminal e fechamento do cólon ascendente por abdome agudo perfurativo devido a uma tuberculose íleo-colônica. Enema opaco mostrava coto proximal do cólon direito próximo da ileostomia. O acesso à cavidade foi feito através do orifício resultante da liberação do ostoma-realização de anastomose íleo-colônica látero-lateral com grampeador circular de 25 mm e fechamento manual do coto ileal. Estas cirurgias exigem táticas próprias, como rigor na lise de aderências, tração dos tecidos e hemostasia, além de demandar destreza do cirurgião; contudo, sem necessidade de investimentos em tecnologia e, além disso, a curva de aprendizado é relatada como menor que a da videolaparoscopia. A laparotomia com incisão mínima deve ser considerada como opção válida e viável no tratamento de afecções cirúrgicas.

A Comparative Study of Surgical Treatment Result in the Ruptured Achilles Tendon: Minimal Incision Percutaneous Repair and Open Repair / 대한정형외과학회잡지

PURPOSE: To compare and analyse the clinical outcomes between minimal-incision percutaneous repair and open repair among the surgical treatments for Achilles tendon ruptures. MATERIALS AND METHODS: We retrospectively analyzed and compared the outcomes between 25 patients with minimal incision percutaneous repair (group 1) and 30 patients with open repair (group 2), from January 2006 to June 2014. The postoperative clinical evaluations were done by Arner-Lindholm scale, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, overall patient's satisfaction, and cosmetic satisfaction of scar. RESULTS: There were statistically significant differences between the two groups with respect to AOFAS hind foot score, mid-calf circumference differences, overall patient's satisfaction, and satisfaction of scar; the group 1 showed better achievement. There was no statistical difference between two groups in regards to other clinical outcomes. In group 1, there were 2 cases of sural nerve hypoesthesia, which fully recovered spontaneously at about 6 months after the surgery. In group 2, there were 3 cases of deep vein thrombosis, re-rupture, and deep infection. CONCLUSION: We recommend minimal incision percutaneous repair as one of the effective surgical treatment options for Achilles tendon ruptures.

Curative effect observation of minimally invasive incision combined with plate fixation for calcaneal fractures / 局解手术学杂志

Objective To analyze the curative effect of minimally invasive incision combined with plate fixation for calcaneal fractures.Methods Retrospectively analyzed the clinical data of 30 cases(30 feet) of calcaneal fractures who were treated with minimal incision(sinus tarsi approach combined with posterior lateral incision) from August 2014 to August 2015.Minimally invasive incision combined with plate fixation were performed for the treatment.X-rays were taken in the regular follow-up,B(o)hler and Gissane angle as well as the complications were measured.The final curative effect was comprehensively assessed according to the ankle hind foot score of American Aryhopaedic Foot and Ankle Society(AOFAS).Results All cases were followed up for an average of 14.5 months (from 12 to 16 months), and all fractures healed with no complication such as incision infection or poor healing.The average B(o)hler angle was improved from preoperative(13.42°±4.2°) to (29.3°±3.8°) at the last follow-up with a significant difference(t=-20.424,P=0.000),and the average Gissane angle was significantly improved from preoperative(97.8°±9.7°) to (123.6°±6.5°) at the last follow-up (t=-17.5,P=0.000).The outcomes were evaluated with AOFAS,resulting in an excellent and good rate of 83.3%.Conclusion Treatment of calcaneal fractures with minimal incision has the advantages of less trauma,lower incision complication rate,stronger reduction and fixation,which can achieve satisfactory outcomes.

Results of Minimal Incision Distal Metatarsal Osteotomy for Moderate to Severe Hallux Valgus / 대한족부족관절학회지

PURPOSE: Minimal incision distal metatarsal osteotomy (MIDMO) is known to be an effective surgical procedure for mild to moderate hallux valgus. However, the result of MIDMO on moderate to severe hallux valgus is controversial; therefore, we investigated the radiological and clinical results of MIDMO on moderate to severe hallux valgus. MATERIALS AND METHODS: We reviewed 51 feet (48 patients) with moderate to severe hallux valgus. The mean age was 67.0 years and the mean follow-up period was 32.2 months. Radiological data of hallux valgus angle, first intermetatarsal angle, and distal metatarsal articular angle on plain radiographs were analyzed. Recurrence, union, lateral translation of distal fragment and angulation were also analyzed. The clinical data were obtained using American Orthopaedic Foot and Ankle Society (AOFAS) score of preoperation and last follow-up. Receiver operating characteristic (ROC) curve was used to determine a cut-off value. RESULTS: The mean hallux valgus angle measured at preoperation was 37.7o and 15.9degrees at last follow-up. The mean first intermetatarsal angle of preoperation and last follow-up were 15.2degrees and 8.3degrees. The mean distal metatarsal articular angle changed from 12.6degrees at preoperation to 7.8degrees at last follow-up. Preoperative hallux valgus angle (p=0.0051) and distal metatarsal articular angle (p=0.0078) were statistically significant factors affecting postoperative AOFAS score. Cut-off value of each was 37degrees and 13degrees, respectively. Lateral translation of distal fragment in 5 recurrent cases was 23.0% compared to 45.3% of 46 non-recurrent cases. The result was statistically significant and the cut-off value was 38%. CONCLUSION: Sufficient lateral translation over 38% in MIDMO on moderate to severe hallux valgus patients with preoperative hallux valgus angle under 37degrees and distal metatarsal articular angle under 13degrees can lead to good clinical results without recurrence.

A Comparative Study of Surgical Treatment in the Ruptured Achilles Tendon: Minimal incision and Open repair / 대한족부족관절학회지

PURPOSE: The purpose of this study was to compare and analyse the clinical outcomes of minimal incision repair and open repair in ruptured Achilles tendon. MATERIALS AND METHODS: We retrospectively analyzed the outcomes of 10 patients with minimal incision repair (group 1) and 19 patients with open repair (group 2) from February 2007 to June 2011. The postoperative clinical evaluations were done by Arner-Lindholm scale, AOFAS score, overall patient's satisfaction and cosmetic satisfaction of scar. RESULTS: There was no statistical difference between two groups in Arner-Lindholm scale, AOFAS score, overall patient's satisfaction (p=1.21, 0.87, 1.07). There was statistically high rate of cosmetic satisfaction in group 1(p<0.001). There were no complications in group 1. Complications occurred in three patients (deep infection, rerupture, deep vein thrombosis) of group 2. CONCLUSION: Treatment of minimal incision repair in Achilles's tendon ruptures showed high rate of cosmetic satisfaction and low rate of complication's, but there were no significant differences with open repair in other clinical outcomes. The minimal incision repair could be recommended as one of the effective treatment for the Achilles's tendon ruptures.

The Treatment of Subtrochanteric Fracture with Cephallomedually Nail: Minimal Incision and Lowman Clamp Assisted Reduction

PURPOSE: To evaluate the radiographic results of patients with subtrochanteric femoral fracture using minimal incision and cephalomedullary nail technique. MATERIALS AND METHODS: This study was performed on 54 patients, 54 cases of hip, recruited among patients who underwent minimal incision and Cephalomedullary nail from September 2005 to August 2008 and were available for 1-year or longer follow up. The gender ratio was 37 males and 17 females, and the mean age at the time of surgery was 57.4 years (range; 16~81 years). According to injury mechanism, traffic accident was 29 cases, fall down form high height was 18 cases, slip down was 7 cases. In classification by Seinsheimer, type II was 23 cases (m/c), type III was 18 cases, type IV was 13 cases. Average follow up period was 14 months (12~18). Radiographic evaluation was performed for time taking union, mal-union and complication. RESULTS: 53 of the 54 cases united. 39 of 54 reductions were anatomic. 19 fractures had a monir varus deformity of proximal fragment (between 2degrees and 5degrees). There was no varus deformity of more than 5degrees. 1 case that had been treated with PFN had nail breakage without trauma. There were no other complications. CONCLUSION: Surgical treatment of subtrochanteric fractures with minimal incision and Cephalomedullary nail technique can reslut in excellent reduction without complications including inflammation & malunion. Careful attention to detail for using Lowman clamp is demanding to decrease soft tissue injury.

Prevention of Cheek Drooping in Intraoral Reduction Malarplasty without Internal Fixation

PURPOSE: In general, orientals including Korean, have a mesocephalic face whereas Caucasians, among the western, have a dolichocephalic face .Unlike the western, in orientals including Korean, prominent malar bones are recognized as stubborn and unattractive appearance. That is why reduction malarplasty is one of the most popular aesthetic surgical procedure in Korea. Many surgical methods to reposition prominent malar bones have been performed by means of a coronal incision or a combined incisions, using both the intraoral and the external incision. Bicoronal approach has advantage such as wide operative field, easy to maintain symmetry and possibility of combining facial lift but has shortcoming, such as external scars, long operative time, and the possibility of facial nerve or artery injury. Intraoral approach has advantages of short operative time, simplicity of procedure and no external scar. But this approach is associated with problems of cheek drooping, limited exposure and difficulty in making symmetry. METHODS: During 8 years, we performed a reduction malarplasty without internal fixation through an minimal intraoral incision and dissection in 39 patients. RESULTS: The patients were followed for 46 months, with satisfactory results and no cheek drooping. There was no patient who want to revise the inappropriate operative result such as asymmetry and incomplete correction. CONCLUSION: We conclude that minimal intraoral incision and dissection could acquire satisfactory result of reduction malarplasty along with prevention of cheek drooping.

Clinical Results of Carpal Tunnel Release with Open Minimal Incision

PURPOSE: To find out the clinical usefulness of carpal tunnel release with open minimal incision MATERIALS AND METHODS: We studied 149 patients (152 carpal tunnel) who were able to follow up for more than 6 months after being treated with carpal tunnel release with open minimal incision from January 2000 to January 2006. We compared the clinical results of this procedure using recovery time, the disappearance of symptoms, the presence of the kelloid and the scar tenderness and analyzed preoperative and postoperative VAS score of tingling sensation, dull sensation, inappropriate hand movement, muscle weakness, edema, palmar pain as subjective satisfaction. We used the independent t-test for the statistical significance. RESULTS: All cases had complete disappearance or marked improvement in symptoms, and there was no kelloid formation. Residual symptoms and tenderness of the scar was found in 8 cases (5.4%), but gradually disappeared. In last follow up, tingling sensation decreased from 7.8 to 1.0 and dull sensation from 7.0 to 1.5, inappropriate hand movement from 4.8 to 1.1, muscle weakness from 5.9 to 0.8, edema from 2.0 to 0.5, palmar pain from 2.1 to 0.2 in preoperative and postoperative VAS score, all were significantly improved statistically (P<0.05). CONCLUSIONS: We think that carpal tunnel release with open minimal incision has little complication and is a safe and effective operation method having similar effect with endoscopic surgery or conventional open surgery.

The Early Results of Linear Distal Metatarsal Osteotomy with Minimal Incision for Correction of Hallux Valgus / 대한족부족관절학회지

PURPOSE: Good results using minimal invasive hallux valgus surgery has been reported recently. We evaluate the usefulness of linear distal metatarsal osteotomy with minimal skin incision in mild and moderate hallux valgus deformity. MATERIALS AND METHODS: Twenty-eight patients (thirty-one cases) who had mild to moderate hallux valgus deformity and underwent linear distal metatarsal osteotomy using minimal skin incision were evaluated between February 2005 and February 2006. Hallux-metatarsophalangeal-interphalangeal scale of AOFAS (American Orthopaedic Foot and Ankle Society) score was used as clinical evaluation. Preoperative, postoperative, after pin removal, and final follow up plain radiographs were used as radiologic evaluation. RESULTS: Twenty-six cases (83%) among thirty-one cases showed more than average satisfaction, Average AOFAS score were improved from 63.2 points (range 45-74 points) to 86.4 points (range 67-93 points). Preoperative radiologic index of IMA 14.0 degrees (range 10-18 degrees), HVA 30.2 degrees (range 19-39 degrees), DMAA 13.8 degrees (range 5-23 degrees) were improved postoperatively as IMA 8.3 degrees (range 5-10 degrees), HVA 10.5 degrees (range 2-20 degrees), DMAA 7.2 degrees (range 0-14 degrees) correctively. Mean operative time was 15.5 minutes (range 11-18 minutes) and mean operative time was 5.6 days (range 2-8 days). CONCLUSION: Despite small skin incision and short operative time and admission period, linear distal metatarsal osteotomy with minimal skin incision showed similar results with conventional distal metatarsal osteotomy. Thus, it was thought to be useful operation in mild and moderate hallux valgus deformity.

Clinical application of the anterolateral acromial approach with minimal incision in the treatment of proximal humerus fracture / 中国矫形外科杂志

[Objective]To evaluate the clinical application and results of the anterolateral acromial approach with minimal incision in the treatment of proximal humerus fracture.[Method]From December 2006 to December 2008,42 patients with proximal humeral fracture were treated by the anterorlateral acromial approach using locking plate.There were 25 males and 17 females.All the fractures were classified with AO/OTA classification.There were 5 A2-fractures,11A3-fractures,7 B1-fractures,12 B2-fractures,3 C1-fractures,4 C2-fractures.Anterolateral acromial approach with minimal incision was applied and the deltoid muscle was seperated to expose the fracture fragments.Under direct vision the direct and indirect reduction of the fractures were performed.The locking plate was inserted distally beneath the deltoid muscle and between the distal plate and the humeral shaft was adjusted through another small skin incision on the lateral upper arm.Locking screws were inserted to the proximal and distal plate.Operation time,incision length,blood loss,reduction,Neer scores at 1 year were analyzed in different time points.[Result]All the cases were completed with minimal incision.There were significant differences(P

Minimal incision osteotomy for tailor's bunion / 中国矫形外科杂志

[Objective] To retrospectively analyze the treatment of tailor's bunion with minimal incision osteotomy,and to investigate the indications and effects of this procedure.[Method]Thirty-seven patients(69 feet)underwent the procedure from July 2002 to August 2007.The axial and lateral films of all feet with loading were taken before and after operation.AOFAS were recorded and analyzed preoperatively and postoperatively.[Result]The forth intermetatarsal angle was 14.36??7.32? before operation and 9.36??2.92?after operation.The unguis aduncus angle of digitus quintus pedis was 20.44??7.36? before operation and 4.36??1.35?after operation.The forth reforming intermetatarsal angle was 10.36??.2.81? before operation and 7.83??2.37?after operation.The exstrophy angle of the fifth metatarsal was 5.46??1.70? before operation and 2.13??0.38?after operation.The score of AOFAS was 45.7?5.6 before operation and 85.3?5.1 after operation.[Conclusion]The treatment of tailor's bunion with minimal incision osteotomy is easy to operate and its therapeutic effect is convincing.

Minimal incision surgery for total hip replacement / 中国矫形外科杂志

[Objective]To explore the advantages and disadvantages of minimal incision surgery(MIS) for total hip replacement.[Methods]Thirty-two patients(37 hips) who had undergone a MIS were compared with 32 patients(37hips) who had undergone conventional incision surgery with similar condictions.The length of incision,operation time,intraoperative blood loss,postoperative drainage,hospitalized days and complications were observed.[Results]The average incision length was 7.7 cm for MIS group and 11.5 cm for conventional incision group(P0.05).In MIS group,greater trochanter fracture occured in 1 patient during operation.Dislocation occurred in another patient with anterolateral approach 3 days postoperatively because of malposition of the cup,the cup was then adjusted to proper position by re-operation with extended incision length.In conventional incision group,no complication occured during or after operations.[Conclusion]Total hip replacement with the incision length of 6～8.5 cm is a very demanding technique.There were no much advantages of MIS for total hip replacement concerning surgical time,blood loss or trauma compare with a conventional incision surgery.The incision length for total hip replacement should not be stressed.The most important thing for total hip replacement is not the length of the incision and the length of incision should not be reduced at the price of more soft tissue injury.

A Minimal-Incision Technique in Total Hip Arthroplasty : Early Postoperative Results and Learning Curve

Purpose: We hereby would like to compare on the basis of the initial 12 hips and latter 18 hips by analyzing the initial results of the minimal incision total hip arthroplasty of 30 hips we experienced. Materials and Methods: For the period of December 2004 through June 2005, we performed the total hip arthroplasty with minimal incision in 10cm or shorter using the posterolateral approach on 25 patients (30 hips) whose BMI(body mass index) is 30 or lower. We compared by analyzing results of the initial 12 cases and 18 latter cases. Results: The average BMI was 23.7. There weren`t statistically meaningful differences the change in the hemoglobin value of pre-op and post-op, necessity of blood transfusion, position of component, and the Harris hip score 6 weeks after operation. But, the average initial operation time of 124 minutes was remarkably reduced to 65 minutes in average in the latter operation and the length of a skin incision was reduced from the average 9.2 cm in the initial operation to an average of 8.1cm in the latter operation. There wasn't the malposition of acetabular cup and femoral stem. Conclusion: Although we need more statistical data through more cases and the analysis of long-term results, we think that, to surgeons with much experience in the conventional total hip arthroplasty, the total hip anthroplasty using minimal incision for patients with BMI of 30 or below would be a useful approach having the advantage in a cosmetic aspect.

Minimal incision hip replacement through the modified Hardinge approach / 中国微创外科杂志

Objective To investigate the feasibility of hip replacement through a minimal incision via modified Hardinge approach.Methods Hip replacement was performed in 21 cases(22 hip joints) from July 2005 to March 2006.The operation was completed through a minimal incision via modified Hardinge approach,with the greater trochanter as the center.There were 12 cases of total hip replacement(13 hip joints) and 9 cases of bipolar femoral head replacement.A biological prosthesis was used in all the cases. Results The mean length of incision was 7.6 cm(range,6.0~9.0 cm),the mean operation time was 76 min(range,(45~)150 min),and the mean blood loss,370 ml(range,190~580 ml).No severe complications occurred.All the cases were followed for a mean of 38 weeks(range,22~53 weeks).Evaluation with the Harris hip score system showed excellent outcomes in 18 cases(19 hips) and good in 3 cases,with a rate of excellent or good results of 100%.Conclusions Minimal incision hip replacement through the modified Hardinge approach has advantages of minimal trauma,little blood loss,low complication rate,and quick recovery.

Surgical Repair of Achilles Tendon Rupture by Minimal Incision Technique / 대한족부족관절학회지

PROPOSE: There have been many debates about the ideal surgical technique for acute Achilles tendon rupture. The purpose of this study is to review and analyze the clinical outcome of the acute Achilles tendon ruptures that had been repaired by indirect suture technique with minimal incision that utilized an instrument called Achillon (Newdeal, France). MATERIALS AND METHODS: This study is based on the 14 cases (14 patients) of acute Achilles tendon total ruptures that have been repaired by minimal incision technique utilizing Achillon instrument from June 2003 to December 2004. Two cases were reruptured before 8 weeks and repaired again using Krackow suture which left 12 feet for postoperative functional evaluation with at least 6 months of follow-up. Ten cases were men and average age at time of injury was 34.4 (26-49) years. The time from injury to surgery was an average of 4.5 (1-9) days and the postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. The ability to return to original work and sports activities as well as patient satisfaction were also evaluated. RESULTS: The follow-up period was averaged for 13.2 (6-24) months. Seventy-one percent of cases were ruptured during sports activities. The ruptured level was the average of 5.1 cm (3.2-8 cm) above calcaneal attachment and the skin incision was averaged for 2.7 cm (2.5-3.0 cm) long. At final follow-up, standing on tip-toe was possible in all cases while the heel-floor height on ruptured side was shorter by 0.7 cm (0-2 cm). By Arner-Lindholm evaluation scale, 9 cases were excellent, and 3 cases were good. Overall AOFAS score was an average of 96.1 (94-100), and all patients were satisfied with the result. Patients returned to work at an average of 1.3 months after the surgery and pre-injury sports activities were all possible from at 6 months after operation. CONCLUSION: Since we have treated acute Achilles tendon ruptures with minimal incision technique utilizing the Achillon and gained encouraging functional results with all patients returning to previous work with high patient satisfaction, this technique could be recommended as one of the ideal surgical options for the Achilles tendon ruptures.
