Abstract
The management of diabetic foot osteomyelitis (DFO) is extremely challenging with high amputation rates reported alongside a five-year mortality risk of more than fifty percent. We describe our experience in using adjuvant antibiotic-loaded bio-composite material (Cerament) in the surgical management of DFO and infected Charcot foot reconstruction. We undertook a retrospective evaluation of 53 consecutive patients (54 feet) who underwent Gentamicin or Vancomycin-loaded Cerament application during surgery. The feet were categorised into two groups: Group 1, with infected ulcer and DFO, managed with radical debridement only (n = 17), and Group 2, requiring reconstruction surgery for infected and deformed Charcot foot. Group 2 was further subdivided into 2a, with feet previously cleared of infection and undergoing a single-stage reconstruction (n = 19), and 2b, with feet having an active infection managed with a two-stage reconstruction (n = 18). The mean age was 56 years (27-83) and 59% (31/53) were males. The mean BMI was 30.2 kg/m2 (20.8-45.5). Foot ulcers were present in 69% (37/54) feet. At a mean follow-up of 30 months (12-98), there were two patients lost to follow up and the mortality rate was 11% (n = 5). The mean duration of post-operative systemic antibiotic administration was 20 days (4-42). Thirteen out of fifteen feet (87%) in group 1 achieved complete eradication of infection. There was a 100% primary ulcer resolution, 100% limb salvage and 76% bony union rate within Group 2. However, five patients, all in group 2, required reoperations due to problems with bone union. The use of antibiotic-loaded Cerament resulted in a high proportion of patients achieving infection clearance, functional limb salvage and decrease in the duration of postoperative antibiotic therapy. Larger, preferably randomised, studies are required to further validate these observations.

Abstract
Aims Diabetic foot care is a significant burden on the NHS in England. We have conducted a nationwide survey to determine the current participation of orthopaedic surgeons in diabetic foot care in England. Methods A questionnaire was sent to all 136 NHS trusts audited in the 2018 National Diabetic Foot Audit (NDFA). The questionnaire asked about the structure of diabetic foot care services. Results Overall, 123 trusts responded, of which 117 admitted patients with diabetic foot disease and 113 had an orthopaedic foot and ankle surgeon. A total of 90 trusts (77%) stated that the admission involved medicine, with 53 (45%) of these admissions being exclusively under medicine, and 37 (32%) as joint admissions. Of the joint admissions, 16 (14%) were combined with vascular and 12(10%) with orthopaedic surgery. Admission is solely under vascular surgery in 12 trusts (10%) and orthopaedic surgery in 7 (6%). Diabetic foot abscesses were drained by orthopaedic surgeons in 61 trusts (52%) and vascular surgeons in 47 (40%). Conclusion Orthopaedic surgeons make a significant contribution to both acute and elective diabetic foot care currently in the UK. This contribution is likely to increase with the movement of vascular surgery to a hub and spoke model, and measures should be put in place to increase the team based approach to the diabetic foot, for example with the introduction of a best practice tariff.

Abstract
AIMS In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method. METHODS We conducted a retrospective analysis of prospectively collected data of all patients with infected Charcot foot deformity who underwent two-stage reconstruction with internal fixation between July 2011 and November 2019, with a minimum of 12 months' follow-up. RESULTS We identified 23 feet in 22 patients with a mean age of 56.7 years (33 to 70). The mean postoperative follow-up period was 44.7 months (14 to 99). Limb salvage was achieved in all patients. At one-year follow-up, all ulcers have healed and independent full weightbearing mobilization was achieved in all but one patient. Seven patients developed new mechanical skin breakdown; all went on to heal following further interventions. Fusion of the hindfoot was achieved in 15 of 18 feet (83.3%). Midfoot fusion was achieved in nine of 15 patients (60%) and six had stable and painless fibrous nonunion. Hardware failure occurred in five feet, all with broken dorsomedial locking plate. Six patients required further surgery, two underwent revision surgery for infected nonunion, two for removal of metalwork and exostectomy, and two for dynamization of the hindfoot nail. CONCLUSION Two-stage reconstruction of the infected and deformed Charcot foot using internal fixation and following the principle of 'long-segment, rigid and durable internal fixation, with optimal bone opposition and local antibiotic elusion' is a good form of treatment provided a multidisciplinary care plan is delivered.

Abstract
Diabetic Foot Infection (DFI), in its severest form the acute infected 'diabetic foot attack', is a limb and life threatening condition if untreated. Acute infection may lead to tissue necrosis and rapid spread through tissue planes, in the patient with poorly controlled diabetes facilitated by the host status. A combination of soft tissue infection and osteomyelitis may co-exist, in particular if chronic osteomyelitis serves as a persistent source for recurrence of soft tissue infection. This "diabetic foot attack" is characterised by acutely spreading infection and substantial soft tissue necrosis. In the presence of ulceration, the condition is classified by the Infectious Diseases Society of America/International Working Group on the Diabetic Foot (IDSA/IWGDF Class 3 or 4) presentation requiring an urgent surgical intervention by radical debridement of the infection. Thus, 'time is tissue', referring to tissue salvage and maximal limb preservation. Emergent treatment is important for limb salvage and may be life-saving. We provide a narrative current treatment practices in managing severe DFI with severe soft tissue and osseous infection. We address the role of surgery and its adjuvants, the long term outcomes, potential complications and possible future treatment strategies.

Current concepts and challenges in managing ankle fractures in the presence of diabetes: A systematic review of the literature. J Clin Orthop Trauma 2021; 17:44-53.

Abstract
BACKGROUND Ankle fractures in diabetic patients are known to have an increased morbidity. This systematic review aims to evaluate the current evidence in terms of risk profile and inform treatment options. METHODS Following the methodology of the Cochrane collaboration, an extensive literature search was conducted. Outcomes included, complications, operative and non-operative management and early weight-bearing. RESULTS A total of 40 studies were included. Complication rates were higher in diabetic patients and more so in poorly controlled diabetes, IDDM, or "complicated" diabetes. Supplementary fixation was associated with lower complication rates. Regarding early weight-bearing, similar results to non-diabetics in the stable fracture pattern were found providing there was no evidence of neuropathy. CONCLUSION Diabetes, especially complicated diabetes, presents an increased risk of complications. However non operative management of diabetic ankle fractures do poorly, and with the use of 'ORIF plus' techniques there is no increase in complications from early fixation. The use of external fixation for definitive fixation should be minimised as it is associated with high complication rates.

Abstract
Surgery for acute and chronic diabetic foot problems has long been an integral component of care. While partial foot amputations remain as important diabetic limb-salvaging operations, foot-sparing reconstructive procedures have become equally important strategies to preserve the functional anatomy of the foot while addressing infection, chronic deformities, and ulcerations. A classification of types of diabetic foot surgery is discussed in accordance with the soft tissue status and acuity of the presenting foot problem. This brief overview from the Association for Diabetic Foot Surgeons describes common conditions best treated by surgical interventions, as well as specific indications. While techniques and indications continue to evolve, effective surgical management of the diabetic foot remains an integral component of care as well as for the prevention of recurrent ulceration.

Abstract
Comprehensive management of a severe diabetic foot infection focus on clear treatment pathways. Including rapid, radical debridement of all infection in addition to intravenous antibiotics and supportive measures. However, inexperienced surgeons can often underestimate the extent of infection, risking inadequate debridement, repeated theatre episodes, higher hospital morbidity, and hospital length of stay (LOS). This study aims to assess protocolized diabetic-foot-debridement: Red-Amber-Green (RAG) model as part of a value-based driven intervention. The model highlights necrotic/infected tissue (red-zone, nonviable), followed by areas of moderate damage (amber-zone), healthy tissue (green-zone, viable). Sequential training of orthopedic surgeons supporting our emergency service was undertaken prior to introduction. We compared outcomes before/after RAG introduction (pre-RAG, n = 48; post- RAG, n = 35). Outcomes measured included: impact on number of debridement/individual admission, percentage of individuals requiring multiple debridement, and length-of-hospital-stay as a function-of-cost. All-patients fulfilled grade 2/3, stage-B, of the Texas-Wound-Classification. Those with evidence of ischemia were excluded. The pre-RAG-group were younger (53.8 ± 11.0 years vs 60.3 ± 9.2 years, P = .01); otherwise the 2-groups were matched: HbA1c, white blood cell count, and C-reactive protein. The post-RAG-group underwent significantly lower numbers of debridement's (1.1 ± 0.3 vs 1.5 ± 0.6/individual admission, P = .003); equired fewer visits to theatre (8.6% vs 38%, P = .003), their LOS was reduced (median LOS pre-RAG 36.0 vs post-RAG 21.5 days, P = .02). RAG facilitates infection clearance, fewer theatre-episodes, and shorter LOS. This protocolized-management-tools in acute severely infected diabetic foot infection offers benefits to patients and health-care-gain.
