چکیده
PURPOSE OF THE STUDY The Minimally Invasive Chevron Akin (MICA) is a percutaneous technique used to correct hallux valgus deformity. combination of distal osteotomy the first metatarsal and proximal phalanx big toe stabilized with internal fixation was over last decade. retrospective study presents results measurements performed on preoperative postoperative X-rays offers comparison conventional osteotomies. MATERIAL AND METHODS population consists 76 patients who underwent 93 operations between 2015 2018 at Department Orthopaedics, 1st Faculty Medicine, Charles University in Prague. mean age 50.2 years (range 18-74 years). evaluates measures parameters attributes interest weight-bearing foot before after operation 6-week or 3-month follow-ups. intermetatarsal angle measured according mechanical anatomic axis bone. Apart from that, displacement head osteotomy, articular were analysed. position medial sesamoid bone congruency metatarsophalangeal joint evaluated as well. RESULTS 33.2° ± 7.3° 10.2° 5.8° postoperatively. value decreased 12.4° 2.8° 7.4° 2.5° increased 13.7° 3.6° 17.4° 4.6°. restored 85 cases (91%). lateral fragment 50% its width 18% 84%). X-ray exposure during 0.58 mGy personnel exposed radiation for 79 seconds average. DISCUSSION One many questions raised regard surgery choice right order achieve proper toe. surgeon should have opportunity use that provides possibility change orientation surface three planes. Our found out using MICA transversal plane 4 mm 18 (in 20 diameter head). method thus mild, moderate partially severe deformities main disadvantage necessity C-arm operating theatre. CONCLUSIONS deformity based two extraarticular osteotomies part stable screws sagittal, transversal, even frontal plane, useful mild deformities.

Treatment of Pseudoarthrosis After Minimally Invasive Hallux Valgus Correction
OBJECTIVE Treatment of mild and moderate hallux valgus deformities. DISCUSSION Minimally invasive technique enables surgeons to treat mild and moderate hallux valgus deformities with excellent and good results in the majority of patients. Nonunion of first metatarsal, moreover, has only rarely been reported. SUMMARY We describe the essential steps of a surgical technique for the treatment o...

A case-controlled study of minimally invasive vs open hallux valgus surgery
Methodology This is a consecutive case series performed between 2009 and 2012. This includes the learning curve for minimally invasive surgery. All cases were performed by a single surgeon at two different sites, one centre where minimally invasive surgery is available and the other where it is not. The standard procedure in both centres is a modified Chevron osteotomy. Regardless of whether th...
متن کاملRevision Hallux Valgus Surgery
Foot and ankle surgeons routinely perform surgery of the fi rst ray, such as correction of hallux valgus deformity. The complication rate in hallux valgus surgery ranges between 10% and 55%. 1 Although hallux valgus surgery is common, several common complications can occur that necessitate revision. There are several causes of hallux valgus surgery failure; often, potential complications can be...
