Objective To evaluate the clinical and radiological results in the treatment of moderate Hallux valgus with a minimally invasive system: Mini Tightrope ® (MTR). Material and methods We selected 32 patients, 36 feet (4 bilateral), with moderate Hallux valgus according to the criteria of Mann and Coughlin, and performed the Mini Tightrope ® modified technique. The American Orthopaedic Foot and Ankle Society (AOFAS) scale, the measurement of intermetatarsal angle (IMA) and metatarsophalangeal (MTT-F), sesamoid position, first toe mobility and the level of satisfaction, were assessed in these patients. Results A mean score of 88.0 points was obtained on the AOFAS scale (47.7 preoperative) after 24 months. In the last visit the radiographic correction of the IMA and the AH was 4.8° and 10.0° on average, respectively. There were 6 complications during follow-up (16%), 2 of which led to the patient being reoperated. Discussion and conclusions The Mini Tightrope ® is a reproducible technique that allows the treatment of moderate Hallux valgus. It achieves the same correction as osteotomies but preserving and avoiding the complications arising from those, being similar to less invasive percutaneous techniques. However, it is not without complications, some of them specific to this technique, which need to be determined. |
