Research summary
To investigate the long term patient reported outcome measures and radiographs of patients who have undergone minimally invasive surgery for hallux valgus (bunions) using the MICA (Minimally Invasive Chevron Akin) technique. Minimally invasive, also referred to as percutaneous (done through the skin) bunion surgery involves the use of systematically placed small skin incisions which are used to introduce specialised instruments to allow, under the guidance of an intra-operative X-ray machine, the cutting and movement of bones and release of soft tissues where required to correct a bunion deformity which is securely held with specialised screws. MICA is the most modern, 3rd generation, version of minimally invasive bunion correction techniques and, although short term results are equivalent to if not better than its open surgical counterpart. Minimally invasive bunion corrections have been shown to result in similar corrections of deformity and functional outcome with no increase in complications. Early benefits over open surgery have been demonstrated such as lower infection and wound problem rates, less post-operative pain, better range of motion, and minimal scars. Although early results are very promising, reports on medium and long term outcomes are lacking. This study aims to investigate the patient reported outcome measures and X-ray measurements of bunion correction in the medium to long term.
