Introduction. Diabetes is increasing on a global scale. By 2030, 10% of the global population, ½ billon people, are predicted to have diabetes. Potentially there will be a corresponding increase in number of patients referred for surgery. Traditional surgical management of these patients is challenging. Presented is a case series utilizing
Background:. Previous attempts at small incision hallux valgus surgery have compromised the principles of bunion correction in order to minimise the incision. The
There are many different procedures described for the correction of hallux valgus deformity. Minimally invasive surgery has become increasingly popular, with clinical and radiological outcomes comparable to traditional open osteotomy approaches. There is increasing interest in hallux valgus deformity correction using third-generation minimally invasive chevron akin osteotomy (MICA) technique. To assess the radiographic correction and 2 year clinical outcomes of third-generation MICA using validated outcome measures.Background
Objective
First metatarsophalangeal joint (MTPJ) arthrodesis plays a significant role in the management of symptomatic hallux rigidus. Several open and very few percutaneous techniques have been described in the literature. The authors present a new minimally invasive technique along with patient reported outcome, radiological parameters and a discussion on this novel technique. A total of fifteen cases of first MPTJ arthrodesis were included in this prospective continuous series from September 2011 to June 2012. Mean age was 56 years and the indication for surgery was hallux rigidus in 13 of 15 cases. All patients underwent the same minimally invasive procedure by the same primary surgeon (AHS), 13 of 15 as day cases. Clinical outcome and patient satisfaction were assessed by the Manchester-Oxford Foot Questionnaire (MOXFQ) preoperatively and at most recent follow up. Radiographic and clinical evaluation of fusion was also assessed. No patients were lost to follow up and all scores were collected by an independent surgical practitioner to avoid bias. Mean follow up was six months (range 1 to 9 months). The MOXFQ score for cases where fusion was achieved (n=14) improved from a mean 40/64 preoperatively to a mean 15/64 at last follow up ( This minimally invasive technique for first MTPJ arthrodesis is simple and can achieve results similar or better than open techniques in experienced hands. Further cases are needed to expand this series and evaluate for further complications.
Optimal management of displaced intra-articular calcaneal fractures remains controversial. The aim of this prospective cohort study was to compare the clinical and radiological outcomes of minimally invasive surgery (MIS) versus non-operative treatment in displaced intra-articular calcaneal fracture up to 2-years. All displaced intra-articular calcaneal fractures between August 2014 and January 2019 that presented to a level 1 trauma centre were considered for inclusion. The decision to treat was made by a multidisciplinary meeting. Operative treatment protocol involved sinus tarsi approach or percutaneous reduction & internal fixation. Non-operative protocol involved symptomatic management with no attempt at closed reduction. All fractures were classified, and the MOXFQ/EQ-5D-5L scores were used to assess foot and ankle and general health-related quality of life outcomes respectively.Background
Methods
MIS (minimally invasive surgery) aims to improve cosmesis and facilitate early recovery by using a small skin incision with minimal soft tissue disruption. When using MIS in the forefoot, there is concern about neurovascular and tendon damage and cutaneous burns. The aim of this anatomical study was to identify the structures at risk with the proposed MIS techniques and to determine the frequency of iatrogenic injury. 10 paired normal cadaver feet were used. All procedures were performed using a mini C-arm in a cadaveric lab by 2 surgeons: 1 consultant who has attended a cadaveric MIS course but does not perform MIS in his regular practice (8 feet), and 1 registrar who was supervised by the same consultant (2 feet). In each foot, the surgeon performed a lateral release, a MICA (minimally invasive chevron and Akin) procedure for the correction of The dorsal medial cutaneous and the plantar interdigital nerves were intact in all specimens. There was no obvious damage to the arterial plexus supplying the first metatarsal head. No flexor or extensor tendon injuries were identified. There is a significant learning curve to performing the osteotomy cuts in the desired plane. In the DMO, the dissection also revealed some intact soft tissue at the osteotomy site indicating that the metatarsal heads were not truly floating.Materials and Methods
Results
Open Prospective study of 47 patients. 22 patients had MIS In the MIS group, the median follow up was 11 months (4–23). The median preoperative MOXFQ score was 34/64(23) and the median postoperative score was 19/64 (p = <0.02). In the open group the median follow up was 17 months (9–27). The median preoperative MOXFQ score was 35/64 and the median postoperative score was 7.5/64 (p = <0.0001). The metric score of the three domains of the MOXFQ showed statistical improvement in both groups. The improvement didn't reach statistical significance between the open and MIS groups. There were three failures in the open group (Fusion) compared to none in the MIS.Methods
Results
I consider the term ‘minimally invasive surgery’ (MIS) to represent a wide range of techniques directed at achieving a surgical objective with less collateral tissue damage. The surgeon choosing to employ such techniques may aspire to achieve improved or more consistent outcome for their patients but is this so? What are the complications? In certain areas of surgery the concept of MIS is well established (e.g. knee and ankle arthroscopy). In forefoot surgery the concept has been met with interest but also skepticism. Much of this skepticism pivots around concerns that the loss of direct vision (maintained in arthroscopic techniques) may increase the risk of complications. In other words, there is a concern that due to the loss of direct visualization (replaced by intra-operative xray imaging), any benefit that might arise from the less invasive technique of the operation will be negated by either poorer quality of surgical correction or higher risk of injury to adjacent structures. All surgery is associated with a degree of risk and in considering the complications specifically associated with MIS of the forefoot we must try to separate out those complications related to the specific MIS technique involved and those that are not. In other words, we need to identify whether the complication has occurred as a result of incorrect surgical planning (e.g. wrong choice of osteotomy/flaws in surgical objective), poor execution of the surgical technique, or as a result of the MIS instrumentation/equipment. I will discuss the above in relation to my experience of complications encountered whilst employing minimally invasive surgical techniques in the treatment of forefoot pathology over the last 2 years.
We describe our experience with a minimally invasive Chevron and Akin (MICA) technique for hallux valgus correction. This technique adheres to the same principles as open surgical correction but is performed using a specialized high-speed cutting burr under image intensifier guidance via tiny skin portals. All patients undergoing minimally invasive hallux valgus correction between November 2009 and April 2010 were included in this study and were subject to prospective clinical and radiological review. Patients were scored using the Kitaoka score as well as radiological review and patient satisfaction survey. Surgery was performed under general anaesthetic and included distal soft tissue release, Chevron and Akin osteotomies, with the same indications as for open surgery. All osteotomies were internally fixed with cannulated compression screws.Introduction

In recent years the Weil osteotomy has become the dominant technique employed by most surgeons for distal metatarsal osteotomy. This is generally a reliable technique but problems with stiffness can frequently occur in the operated metatarso-phalangeal joints. We present our experience with a minimally invasive distal metatarsal extra-articular osteotomy technique. This technique utilises a high-speed burr via a tiny skin portal to perform a distal metatarsal extra-articular osteotomy under image intensifier guidance without the need for fixation. A consecutive series of 55 osteomies in 21 patients were included in the study. All osteotomies were performed for metatarsalgia/restoration of metatarsal cascade. The mean age was 49 (38-78), and 20/21 were female. The senior author performed all surgery. All patients were allowed to weight bear immediately in a postoperative shoe and then an ordinary shoe from 4-6 week post-operatively. Mean follow-up was 8 months (4-13) and patients were assessed clinically and scored using the AOFAS scoring system and a subjective outcome score. The mean AOFAS score improved significantly postoperatively. All patients were very satisfied/satisfied with the outcome. Two patients had minor superficial portal infections, which resolved with oral antibiotics. One patient reported irritating numbness and stiffness in toes (1st case performed). Most patients reported swelling persisting to 3-4 months. There was one symptomatic delayed at 4 months treated successfully with short air boot immobilisation. There were no mal unions. This series suggests that MIS distal metatarsal osteotomy results compare well with outcomes reported with modern open techniques such as the Weil. We now favour an MIS distal metatarsal osteotomy technique for most indications due to the minimal stiffness observed postoperatively as well as much reduced surgical time without the need for tourniquet.
Minimally invasive chevron and akin osteotomy are being used in a few centres in the UK. The purpose of our study was to analyse our early results and present our early experience of minimally invasive chevron and akin osteotomy (MICA) for the correction of mild to moderate hallux valgus. This study assessed the radiological and clinical measurements, American Orthopaedic Foot and Ankle Society (AOFAS) scores, pain scores and patient satisfaction associated with performance of the MICA, for the treatment of hallux valgus. Between September 2010 and April 2012, 96 consecutive patients (122 feet) who underwent MICA were assessed. The overall satisfaction rate was over 90%. The mean total AOFAS score was 89.7 points. VAS for pain reduced from a mean of 7.4 to less than 1 point. On weight bearing anterior-posterior foot radiographs there was a significant improvement in the mean IMA and HVA. Complications included 2 episodes of superficial infection (1.6%), 1 fracture (0.8%), 4 incidence of nerve injury (3.3%) (Numbness) and 9 patients requiring removal of screw (7.4%). However, these screw removals occurred early on in the study and diminished after a slight modification in surgical technique. Based on our findings we concluded that MICA is an effective procedure with good patient satisfaction in the treatment of mild to moderate hallux valgus.
Introduction:. The surgical treatment of intractable metatarsalgia has been traditionally been an intra-articular Weil's type of metatarsal osteotomy. In such cases, we adopted the option of performing a minimally invasive distal metaphyseal metatarsal ostetomy (DMMO) to decompress the affected ray. The meta-tarsophalangeal joint was not jeopardised. We present our outcomes of
