Kavarthapu V, Haldar A. Reconstruction of unstable ankle charcot deformity using a 3-D printed titanium porous block and hindfoot nail - A case report. Foot (Edinb) 2024; 60:102116. [PMID: 39047358 DOI: 10.1016/j.foot.2024.102116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Revised: 06/11/2024] [Accepted: 06/22/2024] [Indexed: 07/27/2024]
Abstract
Charcot neuroarthropathy (CN) of the ankle joint can cause marked bone resorption of the talus resulting in severe deformity and instability. The utilisation of a 3-D printed bespoke titanium porous block that allows the use of an intramedullary calcaneo-tibial nail is an attractive option in such cases that has been reported for use in post-trauma deformities, following tumour resections, in avascular necrosis of talus and for revision of failed total ankle replacements, however has not previously been reported for Charcot ankle reconstructions. We present a novel case and surgical technique illustrating the use of a 3-D printed titanium porous block and hindfoot nail for reconstruction of a deformed and unstable Charcot hindfoot.

Abstract
BACKGROUND There are uncertainties regarding the diagnostic criteria, optimal treatment methods, interventions, monitoring and determination of remission of Charcot neuro-osteoarthropathy (CNO) of the foot and ankle in people with diabetes mellitus (DM). The aims of this systematic review are to investigate the evidence for the diagnosis and subsequent treatment, to clarify the objective methods for determining remission and to evaluate the evidence for the prevention of re-activation in people with CNO, DM and intact skin. METHODS We performed a systematic review based on clinical questions in the following categories: Diagnosis, Treatment, Identification of Remission and Prevention of Re-Activation in people with CNO, DM and intact skin. Included controlled studies were assessed for methodological quality and key data from all studies were extracted. RESULTS We identified 37 studies for inclusion in this systematic review. Fourteen retrospective and observational studies relevant to the diagnosis of active CNO with respect to clinical examination, imaging and blood laboratory tests in patients with DM and intact skin were included. We identified 18 studies relevant to the treatment of active CNO. These studies included those focused on offloading (total contact cast, removable/non-removable knee high devices), medical treatment and surgical treatment in the setting of active CNO. Five observational studies were identified regarding the identification of remission in patients who had been treated for active CNO. We did not identify any studies that met our inclusion criteria for the prevention of re-activation in patients with DM and intact skin who had been previously treated for active CNO and were in remission. CONCLUSIONS There is a paucity of high-quality data on the diagnosis, treatment, and prognosis of active CNO in people with DM and intact skin. Further research is warranted to address the issues surrounding this complex disease.

Abstract
BACKGROUND Ankle, hindfoot, and midfoot arthrodesis surgeries are standard procedures performed in orthopaedics to treat pain and functional disabilities. Although fusions can effectively improve pain and quality of life, nonunions remain a significant concern for surgeons. With the increased availability of computed tomography (CT), more surgeons rely on this modality for increased accuracy in determining whether a fusion was successful. The objective of this study was to report the rates of CT-confirmed fusion following ankle, hindfoot, or midfoot arthrodesis. METHODS A systematic review was performed using EMBASE, Medline, and Cochrane central register from January 2000 to March 2020. Inclusion criteria included studies with adults (<18 years) that received 1 or multiple fusions of the ankle, hindfoot, or midfoot. At least 75% of the study cohort must have been evaluated by CT postoperatively. Basic information was collected, including journal, author, year published, and level of evidence. Other specific information was collected, including patient risk factors, fusion site, surgical technique and fixation, adjuncts, union rates, criteria for successful fusion (%), and time of CT. Once data were collected, a descriptive and comparative analysis was performed. RESULTS Included studies (26, n = 1300) had an overall CT-confirmed fusion rate of 78.7% (69.6-87.7). Individual joints had an overall fusion rate of 83.0% (73-92.9). The highest rate of union was in the talonavicular joint (TNJ). CONCLUSION These values are lower than previous studies, which found the same procedures to have greater than 90% fusion rates. With these updated figures, as confirmed by CT, surgeons will have better information for clinical decision making and when having informed consent conversations.

Evaluation of Adjuvant Antibiotic Loaded Injectable Bio-Composite Material in Diabetic Foot Osteomyelitis and Charcot Foot Reconstruction. J Clin Med 2023; 12:jcm12093239.

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 Surgical reconstruction of deformed Charcot feet carries a high risk of nonunion, metalwork failure, and deformity recurrence. The primary aim of this study was to identify the factors contributing to these complications following hindfoot Charcot reconstructions. METHODS We retrospectively analyzed patients who underwent hindfoot Charcot reconstruction with an intramedullary nail between January 2007 and December 2019 in our unit. Patient demographic details, comorbidities, weightbearing status, and postoperative complications were noted. Metalwork breakage, nonunion, deformity recurrence, concurrent midfoot reconstruction, and the measurements related to intramedullary nail were also recorded. RESULTS There were 70 patients with mean follow-up of 54 months (SD 26). Overall, 51 patients (72%) and 52 patients (74%) were fully weightbearing at one year postoperatively and at final follow-up, respectively. The overall hindfoot union rate was 83% (58/70 patients). Age, BMI, glycated haemoglobin, and prior revascularization did not affect union. The ratio of nail diameter and isthmus was greater in the united compared to the nonunited group (0.90 (SD 0.06) and 0.86 (SD 0.09), respectively; p = 0.034). In those with a supplementary hindfoot compression screw, there was a 95% union rate (19/20 patients), compared to 78% in those without screws (39/50 patients; p = 0.038). All patients with a miss-a-nail hindfoot compression screw went on to union. Hindfoot metalwork failure was seen in 13 patients (19%). An intact medial malleolus was found more frequently in those with intact metalwork ((77% (44/57 patients) vs 54% (7/13 patients); p = 0.022) and in those with union ((76% (44/58 patients) vs 50% (6/12 patients); p = 0.018). Broken metalwork occurred more frequently in patients with nonunions (69% (9/13 patients) vs 9% (5/57 patients); p < 0.001) and midfoot deformity recurrence (69% (9/13 patients) vs 9% (5/57 patients); p < 0.001). CONCLUSION Rates of hindfoot union and intact metalwork were noted in over 80% of patients. Union after hindfoot reconstruction occurs more frequently with an isthmic fit of the intramedullary nail and supplementary hindfoot screws. An intact medial malleolus is protective against nonunion and hindfoot metalwork failure. Cite this article: Bone Joint J 2022;104-B(6):703-708.

Abstract
BackgroundCharcot neuroarthropathy of the ankle and the hindfoot is a complex clinical entity with a high risk of amputation. Charcot neuroarthropathy limb reconstruction has been proposed as a limb-salvaging procedure. However, there was a lack of information on the various available reconstruction methods, including the outcomes and complications. The present study aimed to evaluate the current literature and update on the trends regarding the surgical management of Charcot neuroarthropathy of the ankle and the hindfoot.MethodsAll data published from January 2010 to January 2020 that investigated the methods of fixation and their respective outcomes for the surgical reconstruction in Charcot neuroarthropathy were analyzed. The union rate, amputation rates, and complications associated with these techniques were taken for statistical analysis.ResultsA total of 16 studies fit the inclusion criteria of this study, with four Level-III studies and 12 Level-IV studies were included. Ten studies utilized internal fixation only; five used a combination of internal fixation and circular external fixator, whereby there are three comparative studies between internal and external fixations, and two studies applied combined technique of internal and external fixations (hybrid fixation). One study describes the usage of circular external fixation only.ConclusionsThe use of retrograde intramedullary nail as a treatment of choice in the reconstruction of Charcot neuroarthropathy ankle is recommended before an ulcer occurrence. Hydroxyapatite (HA)- coated screws are recommended for the locking mechanism to prevent migration in Charcot neuroarthropathy due to poor bony quality. Hybrid fixation is recommended for reconstruction in a condition of ulceration and more complex deformity as it provides a higher rate of limb salvage with less soft tissue irritation.

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
Charcot neuroarthropathy is a debilitating condition that frequently leads to skeletal deformity and pedal ulceration in the insensate foot. Results are often poor and no clear guidelines for surgical management exist. Additionally, amputation rates vary widely making it difficult to accurately inform patients of risks. Few studies have assessed outcomes to identify patients for whom reconstruction is likely to fail. The literature is limited, with small sample sizes and mortality infrequently addressed. We performed a retrospective observational study of patients with Charcot neuroarthropathy to assess overall amputation and mortality rates at 30 days, 1 year, and 3 years postreconstruction and evaluated associated risk factors. Rates of infection, re-ulceration, and return to walking were also assessed. We identified 151 patients over a 5-year period. Demographic and clinical characteristics were collected. Descriptive statistics, Cox proportional hazard model, and logistic regression were used. Overall, 22 (14.6%) patients died, and 23 (15.2%) patients advanced to limb amputation postoperatively. End-stage renal disease, peripheral vascular disease, reconstruction during active phase Charcot process, and reconstruction at the ankle or subtalar joint were all associated with poor outcomes. The risk of mortality was 2.5 times higher in patients with end-stage renal disease, and 3.4 times higher among patients with peripheral vascular disease. Patients with ankle or subtalar joint reconstruction were 70% less likely to return to walking compared to medial column reconstruction. Due to these findings, we suggest that patients with such comorbidities be advised of increased risk for complications including failure to return to walking, amputation, and death.

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
Charcot Neuroarthropathy (CN) of the ankle/hindfoot is a devastating condition that results in a loss of alignment, bony malleolar protrusions and frequently leads to ulceration, infection, and amputation. Major limb amputations in this patient population has a 5-year mortality rate approximating 39%-68%. The treatment goal for CN of the ankle/hindfoot is to provide stability with a plantigrade foot that is infection free, shoeable and allows independent weight bearing. The use of a circular frame external fixator is often required when treating patients with CN of the ankle/hindfoot because they often present late with deformity, soft tissue compromise and infection which are contraindications to primary internal fixation. These patients require urgent surgical attention to salvage the limb or risk amputation. In this narrative review article we will discuss the indications, management options, surgical technique, evidence and describe our experience in the use of circular frame external fixation in patients with ankle/hindfoot Charcot Neuroarthropathy.

Abstract
INTRODUCTION Diabetic peripheral neuropathy leads to foot deformity, soft tissues damage, and gait imbalance, all of which can increase the mechanical stress imposed on the foot and give rise to Charcot neuroarthropathy. The current International Working Group of the Diabetic Foot International Guidelines on offloading focus on managing neuropathic foot ulcers related to pressure: only 2 of their 9 recommendations deal with surgical interventions. We assess the role of surgical techniques in off-loading to heal and possibly prevent diabetic foot ulceration. METHODS We systematically analysed published data from January 2000 to November 2020 to assess methods of surgical offloading and associated outcomes for the surgical reconstruction. We tried to identify healing, remission-rates, return to ambulation, complications and limitations. RESULTS Five discrete categories of surgical offloading are used in recalcitrant ulcers: 1. Lesser toe tenotomies; 2. Metatarsal head resection ± Achilles tendon release; 3. Hallux procedures; 4. Bony off-loading procedures in the form of exostectomy; and 5. Complex surgical foot reconstruction. Adjuvant modalities including surgically placed antibiotic delivery systems show promise, but further studies are required to clarify their role and effect on systemic antibiotic requirements. CONCLUSIONS AND IMPLICATIONS Surgery is important to mechanically stabilise and harmonise the foot for long term off-loading and foot-protection. Surgery should not be reserved for recalcitrant cases only, but extended to ulcer prevention and remission. Further comparative studies will benefit surgical decision making to avoid recurrence and define time point when surgical off-loading could protect against irretrievable tissue loss/re-ulceration.

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. [PMID: 33717970 PMCID: PMC7919966 DOI: 10.1016/j.jcot.2021.01.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 01/26/2021] [Accepted: 01/26/2021] [Indexed: 11/22/2022] Open
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
OBJECTIVE A wide range of clinical presentations of Charcot neuroarthropathy of the foot with concomitant osteomyelitis in patients with diabetes has been described. Existing literature provides an equally diverse list of treatment options. The purpose of this systematic review was to assess the outcomes specifically for the surgical management of midfoot Charcot neuroarthropathy with osteomyelitis in patients with diabetes. METHOD A systematic review was conducted by three independent reviewers using the following databases and search engines: Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane Library, EMBASE (Excerpta Medica dataBASE), Google Scholar, Ovid, PubMed and Scopus. Search terms used were: Charcot neuroarthropathy, osteoarthropathy, neuro-osteoarthropathy, neurogenic arthropathy, osteomyelitis, midfoot, foot, ankle, diabetes mellitus, ulceration, wound, infection, surgical offloading, diabetic reconstruction, internal fixation, external fixation. Studies meeting the following criteria were included: English language studies, studies published from 1997-2017, patients with diabetes mellitus surgically treated for Charcot neuroarthropathy of the midfoot (specified location) with concomitant osteomyelitis, with or without internal and/or external fixation, follow-up period of six months or more postoperatively, documentation of healing rates, complications, and need for revisional surgery. Studies which were entirely literature reviews, descriptions of surgical-only technique and/or cadaveric studies, patients without diabetes, studies that did not specify location of osteomyelitis and Charcot neuroarthropathy, and treatment proximal to and including Chopart's/midtarsal joint specifically talonavicular, calcaneocuboid, subtalar, ankle were excluded. RESULTS A total of 13 selected studies, with a total of 114 patients with diabetes of which 56 had surgical treatment for midfoot Charcot neuroarthropathy with osteomyelitis, met the above inclusion criteria and were used for data extraction. CONCLUSION Surgical intervention for midfoot Charcot neuroarthropathy with osteomyelitis in patients with diabetes demonstrated a relatively high success rate for a range of procedures including debridement with simple exostectomy, arthrodesis with or without internal or external fixation, and advanced soft tissue reconstruction. However, this systematic review emphasises the need for larger, better designed studies to investigate the efficacy and failure rates of surgical treatment in this group of patients.

[PMID: 32405193 PMCID: PMC7211810 DOI: 10.1016/j.jcot.2020.03.025] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 03/26/2020] [Accepted: 03/27/2020] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Charcot neuroarthropathy is a complex condition characterised by progressive deformity, limited treatment options and a high amputation rate. Surgical reconstruction of Charcot foot has been proposed as a method to preserve the foot. However, limited information exists on the different methods of reconstruction available, their outcomes and complications. METHODS We systematically analysed published data from Jan 1993 to Dec 2018 to assess methods of fixation and associated outcomes for the surgical reconstruction in Charcot neuroarthropathy. Statistical analyses were undertaken to determine the amputation rates, return to ambulation and complications associated with these techniques. RESULTS A total of 1116 feet (1089 patients) were reported to have undergone reconstruction with significant heterogeneity in patient selection. Of these, 726 (65%) were reported to undergo internal fixation, 346 feet (31%) external fixation and 44 (4%) undergoing simultaneous internal and external fixation. No single technique demonstrated a significant benefit over the other. Overall, the bone fusion rate was 86.1%. Complications directly attributable to the technique employed were noted in 36% of individuals. The reported post-reconstruction amputation rate was only 5.5% with 91% apparently returning to ambulation. CONCLUSIONS Although no preferential method of fixation was identified, we find that the current options for surgical reconstruction could offer limb salvage with a low amputation risk in a highly selected population. However, the lack of controlled studies, inconsistent reporting of outcomes and heterogeneity of patient selection mean that the quality of evidence is low.

Abstract
Reconstruction of the diabetic Charcot foot can be a challenge even for the most experienced foot and ankle surgeon. The first portion of this article discusses the preoperative evaluation with an emphasis on factors that can be modified before surgical reconstruction to help optimize surgical results. The second portion of the article focuses on intraoperative methods and techniques to help improve postoperative outcomes. Surgeons should strive to provide high-quality, cost-effective care by optimizing patient selection and perioperative care. Objective measures of patient outcomes will become increasingly important with the transition from volume-based to value-based care.
