Abstract
Obtaining clean margins in patients who undergo surgical treatment for diabetic foot osteomyelitis (DFO) is recommended. We hypothesize that the rate of recurrence of the infection is not associated with positive margins, even when using a short-term duration of postoperative antibiotic treatment. We conducted a retrospective pilot study of patients who underwent surgery for DFO confirmed by histopathological analysis of the resected bone from August 1, 2020, to December 1, 2020. Bone samples were taken from the proximal margins to be studied by microbiology and histopathology. Twenty-five (89.3%) patients underwent conservative surgery, and 3 (10.7%) patients underwent a minor amputation. After surgery, the antibiotics were stopped in 19 (67.9%) patients and continued in 9 (32.1%) patients for a median period of 4 days. The microbiology of the bone margins was positive in 20 (71.4%) cases, but the histopathology of the bone margins was positive in just 7 (25%) cases. Recurrence of the infection was detected in 3 (10.7%) patients. Seventeen (68%) patients with microbiological-positive margins did not have a recurrence of infection, while 3 (100%) patients had a recurrence of infection (P = .53). Six (24%) patients among those with histopathological-positive margins did not have a recurrence of infection, and1 (33.3%) patient had a recurrence of infection (P = 1). The recurrence of infection was low and always detected in soft tissues, including the cases with a histopathological-positive bone margin. Postoperative antibiotics were administered for a short period of time and not based on the analysis of bone margins.

Abstract
BACKGROUND There is uncertainty regarding the optimal surgical intervention for diabetic foot osteomyelitis (DFO). Conservative surgery-amputation-free resection of infected bone and soft tissues-is gaining traction as an alternative to minor amputation. Our primary objective was to explore the comparative effectiveness of conservative surgery and minor amputations in clinical failure risk 1 year after index intervention. We also aimed to explore microbiological recurrence at 1 year, and revision surgery risk over a 10-year study period. METHODS Retrospective, single-center chart review of DFO patients undergoing either conservative surgery or minor amputation. We used multivariable Cox regression and Kaplan-Meier estimates to explore the effect of surgical intervention on clinical failure (recurrent diabetic foot infection at surgical site within 1 year after index operation), microbiological recurrence at 1 year, and revision surgery risk over a 10-year follow-up period. RESULTS 651 patients were included (conservative surgery, n = 121; minor amputation, n = 530). Clinical failure occurred in 34 (28%) patients in the conservative surgery group, and in 111 (21%) of the minor amputation group at 1 year (P = .09). After controlling for potential confounders, we found no association between conservative surgery and clinical failure at 1 year (adjusted hazard ratio [HR] 1.3, 95% CI 0.8-2.1). We found no between-group differences in microbiological recurrence at 1 year (conservative surgery: 8 [6.6%]; minor amputation: 33 [6.2%]; P = .25; adjusted HR 1.1, 95% CI 0.5-2.6). Over the 10-year period, the conservative group underwent significantly more revision surgeries (conservative surgery: 85 [70.2%]; minor amputation: 252 [47.5%]; P < .01; adjusted HR 1.3, 95% CI 0.9-1.8). CONCLUSION We found that with comorbidity-based patient selection, conservative surgery in the treatment of DFO was associated with the same rates of clinical failure and microbiological recurrence at 1 year, but with significantly more revision surgeries during follow-up, compared with minor amputations. LEVEL OF EVIDENCE Level III, retrospective comparative effectiveness study.

Abstract
Conservative surgery of diabetic foot osteomyelitis (DFO) in which bone infection is removed without amputation could minimize the biomechanical changes associated with foot surgery. We hypothesize that patients who undergo conservative surgery will have a longer survival time without recurrence of foot ulcers and further amputations than those who undergo any type of amputation to treat DFO. We assessed a retrospective cohort of 108 patients who underwent surgery for DFO from January 2011 to December 2012. Patients were followed-up until May 2020. Reulceration and reamputation-free survival times were plotted using the Kaplan-Meier method and were calculated from the date of first surgery to recurrence, new amputation, or end of the study. A stratified log rank was used to study differences among groups. Cumulative survival without recurrences at 1, 5, and 8 years was 95%, 36%, and 29%, respectively, in patients who underwent conservative surgery and 95%, 43%, and 30%, respectively, in those undergoing amputation. Cumulative survival without a new amputation at 1, 5, and 8 years was 100%, 80%, and 80%, respectively, in patients who underwent conservative surgery and 98%, 82%, and 69%, respectively, in those undergoing amputation. No differences were found regarding either recurrence (log rank, P = .98) or new amputations (log rank, P = .64). In conclusion, conservative surgery is as safe as amputation to arrest bone infection in the feet of patients with diabetes. Conservative surgery was not associated with a lower rate of recurrence and new amputations than those patients who underwent amputations.

Abstract
The cause of diabetic foot complications is often multifactorial; therefore, expertise from multiple surgical and medical specialties is warranted for improved clinical outcomes. Teamwork should be carefully coordinated with strategic planning and treatment should be adaptable to the given clinical scenario. This article describes the formation and interplay of an effective multidisciplinary team for the treatment of the diabetic foot analogous to that seen in elite team sports.

Abstract
BACKGROUND Osteomyelitis of the diabetic foot is a very challenging condition and amputation is often indicated. In some cases where the infection is localized and the surrounding soft tissue is mildly involved, an internal pedal amputation (IPA) based on resection and limited excision of the infected bone have been suggested as a viable option. This systematic review aims to look for the effectiveness of this technique in treating selected cases of diabetic foot osteomyelitis. METHODS A systematic literature search was conducted using multiple electronic databases from inception. Eight studies met the inclusion criteria; one retrospective comparative study, six retrospective observational studies and one prospective observational study. RESULTS Based on a pooled sample of 545 patients followed over a mean period of 27.7 ± 15.2 months, the weighted results were as follows: (a) healing rate was 87.7% (95% CI = 0.757-0.959), (b) time for healing was 7.1 ± 2.9 weeks, (c) wound infection rate was 5.6% (95% CI = 0.030-0.089), (d) wound dehiscence rate was 8% (95% CI = 0.010-0.204), (e) ulcer recurrence rate was of 10% (95% CI = 0.037-0.188), and (f) amputation rate was 2.8% (95% CI = 0.001-0.085) whilst all were minor amputations. CONCLUSION The findings support the selection of toe/ray sparing surgery via IPA as a viable surgical option for selected cases of focal osteomyelitis secondary to diabetic foot infection. The results would indicate that when the ulcer size could be adequately reduced, removing the infected bone while preserving the soft tissue envelope could yield high chance of success with few serious complications.

Abstract
Studies have demonstrated the importance of preserving plantar surface area, lever arm length, and plantar soft tissues in affording patients a plantigrade, stable, and functional limb. We describe a case of a patient who underwent internal pedal amputation that was amenable to functional bracing. The purpose of this case study is to present internal pedal amputation as a viable option to eradicate infection and produce a plantigrade, stable foot that is amenable to custom bracing.

Abstract
Prevention of amputation has become a key objective of clinicians providing care to patients with high-risk diabetic foot problems. In this regard, the multidisciplinary diabetic foot team (MDFT) has been embraced as the most effective way to manage patients with foot ulcers, infections, and Charcot feet. Importantly, such specialized teams have also integrated various surgical specialties to enable more expedient management of these often complex conditions. Experienced diabetic foot surgeons over the last three or four decades have contributed much to this discipline, whereby foot-sparing reconstructive procedures or minor amputations have become fundamental strategies for limb preservation teams. Central to limb salvage, of course, is the recognition of underlying vascular insufficiency and the importance of prompt (endo)vascular intervention. Restoration of adequate perfusion is essential to allow the podiatric, orthopaedic, or plastic surgeon to perform indicated functional reconstructive or minor amputation procedures. This evidence-based overview discusses the various indications and surgical principles inherent in modern concepts aimed at preventing amputation in the high-risk diabetic foot.

Abstract
From January 2007 to December 2009, 207 diabetic patients were consecutively admitted to our foot center because of osteomyelitis of a phalanx or metatarsal head. The removal of infected bone was performed by internal bone resection in 110 patients (group A) and amputation in 97 patients (46.9%; group B). Dehiscence occurred in 15 patients (13.6%) patients in group A and 10 patients (10.3%) in group B (p = 0.464). A total of 206 patients (99.5%) were followed up from January 1, 2007 to December 31, 2011. Ulcer relapse occurred in 12 patients (12.4%) in group A and 18 patients (16.4%) in group B (p = .437). A contralateral ulcer occurred in 10 group A patients (10.3%) and 14 group B patients (12.7%; p = .667). The results of the present study have demonstrated that bone resection with preservation of the soft tissue envelope is feasible in approximately one half of diabetic patients with forefoot osteomyelitis and does not result in any risk of major dehiscence or ulcer recurrence compared with ray or toe amputation.

Abstract
The treatment of 31 consecutive adult patients, ages 25–67 years with chronic draining osteomyelitis (12 cases) or infected pseudarthrosis (19 cases) by the Papineau technique was retrospectively reviewed. The initial injury was an open fracture in 24 patients and a closed fracture in 7 patients. In all cases an Ilizarov circular external fixation device was used for the stabilization of the fracture or for bone lengthening. Mean follow-up for the group was 20 months (range, 10 months to 5 years) and there was successful limb salvage in all cases with eradication of infection and bone consolidation was achieved. The Ilizarov circular external fixation was removed at a mean of 18 weeks (range, 14–24 weeks). The mean time to bone union was 5 months (range, 4–10 months). All patients returned to their pre-treatment activity levels or better.

Abstract
Despite modern surgical techniques and advanced antimicrobial therapy, open lower-extremity fracture management and osteomyelitis remain a challenge for reconstructive surgeons. Posttraumatic composite bone and soft tissue defects are usually the result of high-energy trauma and are often associated with concomitant injuries, therefore making complex reconstruction more difficult. This article presents a case report of an open distal tibial fracture managed by a simultaneous distraction osteogenesis and Papineau technique with a long term follow-up and literature review.

Abstract
Ray resection for localized necrosis, infection, and osteomyelitis is an accepted procedure allowing removal of the diseased toe and metatarsal. The traditional approach involves a rather lengthy incision and dissection that can compromise the vascular supply to the remaining forefoot. The use of minimum incision techniques to perform metatarsal ray resection as presented here represents a simple, reliable, and easily reproduced procedure that limits soft-tissue dissection and the associated wound healing-related complications inherent to the traditional approach. Following minimum incision metatarsal ray resection, the resultant defect from the toe amputation can be primarily closed, covered with a split-thickness skin graft, or closed in delayed primary fashion with the use of a mini-external fixation device. The authors present the proper indications and a step-by-step guide for performing minimum incision metatarsal ray resection with and without the supplemental use of mini-external fixation to close the soft-tissue defect about the toe amputation site.
