Association between the procedure of tibiotalocalcaneal arthrodesis by hindfoot nailing and quality of life in Charcot's joint.

INTRODUCTION: Charcot arthropathy is a progressive disorder of the ankle and foot joints that can lead to foot deformity and instability. Surgical intervention is often necessary for deformity and ulcer management during the chronic phase. The device used for arthrodesis remains a challenge. METHODS: This clinical trial study included diabetic patients aged 40 years or older with Charcot foot. Lateral approach with lateral malleolar osteotomy was used to access the ankle joints and remove the cartilage. A small incision was made on the plantar aspect of the foot to pass an appropriately sized intramedullary nail. Demographic information, medical history, surgical details and Clinical data were collected at 2-week and 1-year follow-ups using the Ankle-Hindfoot Scale (AOFAS) score and the EuroQol 5-Dimensional 5-Level (EQ-5D-5L) health utility score. RESULTS: Twenty-six patients with a mean age of 63 ± 0.23 years were included in the study. The findings showed significant improvements in AOFAS questionnaire items related to pain score, length of the walk, walking surfaces, walking disorders, sagittal alignment, back leg alignment, sustainability, alignment and the total score (P value < 0.001). The EQ-5D-5L questionnaire also showed a significant improvement in the total score (P value = 0.002). CONCLUSION: This study provides evidence supporting the effectiveness of tibiotalocalcaneal arthrodesis by hindfoot nailing in diabetic patients with Charcot foot joints and demonstrated comparable and superior outcomes in terms of patient satisfaction and complication rate when compared to previous studies.

Compressive Strength of Midfoot Fusion Nail vs Midfoot Fusion Bolt and Role of Subtalar Fusion in Midfoot Charcot Fixation Model.

BACKGROUND: Operative management of midfoot Charcot arthropathy often involves an extended midfoot arthrodesis with intramedullary bolts for fixation, a method called "beaming." Recently intramedullary nails have been introduced for the same indication, presumably providing stronger fixation. This study compares midfoot fusion nails to bolts with regard to stiffness and compressive ability. Additionally, we assessed how the addition of a subtalar fusion affects the construct. METHODS: Medial column fusions were performed on 10 matched cadaver foot specimens with either a midfoot fusion nail or bolt. Specimens underwent cyclical compression loading, and displacement was measured. Separately, compressive forces produced were compared between the 2 fixation constructs using a synthetic bone block model. Lastly, another 10 matched specimens with midfoot fusion nails were evaluated with or without subtalar fusions. RESULTS: No differences in stiffness were found in comparing matched specimens between nail vs bolt or comparing nail only without subtalar fusion (STF) vs nail with STF. The compressive force produced by the nail specimens was significantly and substantially greater than the bolted specimens (751.7 vs 139.0 N, P = .01). The accumulated height drop at the midfoot after cycling was 0.5 mm more in the nail group than in the bolt group (1.72 vs 1.22 mm, P = .008). The nail with STF group had greater initial height drop at the midfoot than the nail-only group (0.68 vs 0.34 mm, P = .035) with similar initial height drop at the ankle. However, there were no differences in strength among the matched pairs of midfoot nail-only vs midfoot nail with STF as measured by displacement after fatigue or maximum force at load to failure. CONCLUSION: The overall cadaveric comparisons between matched pairs of nails vs bolts, and nail-only vs nail with STF, did not provide noteworthy differences between the groups with regard to strength or stiffness. However, the compressive force of the midfoot fusion nail was far superior to the bolt in a synthetic bone model. These data provide valuable insight comparing implants used in Charcot midfoot arthrodesis.

Surgical Outcomes in Charcot Arthropathy.

Treatment of Charcot neuroarthropathy (CN) of the foot and ankle remains challenging for both patients and surgeons. Nonoperative treatment with cast/orthosis immobilization has long been the mainstay of treatment, but surgical intervention has gained interest to improve poor long-term outcomes. A review of existing data on the operative management of CN demonstrates the potential benefits but also the continued risks associated with treatment. Additionally, a retrospective review of cohorts managed with limited surgical interventions (wound debridements, exostectomies, and other surgical procedures) compared to reconstructive procedures provides additional insight into the surgical management of CN.

Polymethylmethacrylate (PMMA) Augmentation Enhances the Mechanical Characteristics of Midfoot Beam Constructs in Charcot Neuroarthropathy Cadaver Model.

BACKGROUND: Even with the best conservative care, patients with Charcot neuroarthropathy (CN) of the foot and ankle often ulcerate, increasing their risk of infection, amputation, and death. Surgical fixation has been associated with risk of recurrent ulceration, potentially due to poor bone quality prone to recurrent deformity and ulceration. We propose midfoot beam reconstruction with PMMA augmentation as a novel means of improving fixation. METHODS: A protocol was developed to create characteristic CN midfoot fragmentation both visually and fluoroscopically in each of 12 matched-pair cadaveric feet. Afterward, the pairs were divided into 2 groups: (1) midfoot beam fusion surgery alone, and (2) midfoot beam fusion surgery augmented with PMMA. A solid 7.0-mm beam was placed into the medial column and a solid 5.5-mm beam was placed across the lateral column. In the PMMA group, 8 to 10 mL of PMMA was inserted into the medial column. The hindfoot of each specimen was potted and the metatarsal heads were cyclically loaded for 1800 cycles, followed by load to failure while load and displacement were continually recorded. RESULTS: One specimen in the beam alone group failed before reaching the 1800th cycle and was not included in the failure analysis. The midfoot beam only group demonstrated greater mean displacement during cycle testing compared with the PMMA group, P < .05. The maximum force (N), stiffness (N/mm), and toughness (Nmm) were all significantly greater in the group augmented with PMMA, P < .05. CONCLUSION: In a CN cadaveric model, PMMA augmentation significantly decreased gapping during cyclic loading and nearly doubled the load to failure compared with midfoot beams alone. CLINICAL RELEVANCE: The results of this biomechanical study demonstrate that augmentation of midfoot beams with PMMA increases the strength and stiffness of the fusion construct. This increased mechanical toughness may help reduce the risk of nonunion and infection in patients with neuropathic midfoot collapse.

Intraoperative Radiation Exposure During Midfoot Charcot Reconstruction.

While radiation exposure in foot and ankle surgery varies by procedure, attempts to minimize this hazard remain imperative to protect patients and surgeons. Hindfoot deformity correction employs significant radiation through intraoperative fluoroscopy, however, a paucity of data exists concerning Charcot reconstruction. This investigation describes and compares radiation exposure across varying Charcot pathology and fixation constructs. A retrospective chart review of patients undergoing midfoot Charcot reconstruction under large C-arm assistance from 2016-2022 was conducted. Demographics, pathology-specific, and intervention-specific variables were recorded and compared among midfoot reconstructions. The threshold for statistical significance was set at p ≤ .05. Among 40 patients, the average midfoot radiation exposure and fluoroscopy times were 9.5 ± 5.39 mGy and 256.64 ± 130.67 seconds, respectively. There existed no statistically significant difference in radiation exposure (p = .32) or fluoroscopy times (p = .71) among the different midfoot constructs. There existed a statistically significant relationship between radiation exposure with weight (p = .01) body mass index (p = .03) and number of stages (p = .04). Similarly, a relationship existed between fluoroscopy time with weight (p = .02), body mass index (p = .03), and number of beams/screws (p = .003). Due to the complexity of Charcot reconstruction coupled with multiple robust types of fixation, surgeons must remain cognizant of fluoroscopy usage. Moreover, providers who routinely perform Charcot reconstruction should wear personal protective equipment to protect against radiation.

Midfoot Fusion Using Superconstructs for the Charcot Foot: Current Techniques and Complications.

Neuroarthropathy of the foot and ankle presents a series of challenges. The treating physician faces a perfect storm of pathomechanics, deformity, and medical comorbidities. Successful treatment requires a systematic approach in diagnosis, nonsurgical management, surgical management, and long-term maintenance of the affected extremity. Nonsurgical care of the Charcot foot remains the mainstay of treatment and is successful in most cases. Surgery has become more accepted for patients with severe deformity. The concept of a superconstruct has been introduced to describe modern surgical techniques and implants that have been developed since the early 2000s where stability and durability are maximized. A superconstruct is defined by four factors: (1) fusion is extended beyond the zone of injury to bridge the area of bony dissolution; (2) aggressive bone resection is performed to allow for adequate reduction of deformity without undue tension on the soft-tissue envelope; (3) stronger implants are used than for nonneuropathic fusion procedures, including some specifically developed for fixation of the Charcot foot; and (4) the devices are applied in a position that maximizes mechanical stability to allow the implants to become load sharing. It is important to review the current techniques and implants used in fusion of the neuropathic midfoot and discuss the expected outcomes and complications based on the authors' experience.

Management of Infections and Osteomyelitis in Patients With Charcot Foot Arthropathy.

There is growing interest in performing reconstruction of deformities associated with Charcot foot arthropathy. At least half of the patients undergoing this reconstruction will have chronic wounds and osteomyelitis overlying the deformity. It is important to provide orthopaedic surgeons with tools for making the diagnosis of osteomyelitis in this patient population and creating a strategy for treatment.

Resumen: La artropatía de Charcot se define como un padecimiento articular degenerativo, crónico y progresivo que se caracteriza por lesiones óseas destructivas sin presencia de infección. La neuropatía está asociada directamente con la diabetes mellitus tipo 1 y 2. La cirugía está indicada cuando existe compromiso de partes blandas, inestabilidad de las articulaciones del tobillo y pie, cuando se desarrollan úlceras recurrentes o no es posible adecuar el tobillo o el pie a un calzado normal o en los pacientes que presentan deformidad severa, úlceras o dolor crónico y limitación para realizar las actividades de la vida diaria. El presente es un trabajo observacional, prospectivo, transversal y descriptivo de pacientes con diagnóstico de neuroartropatía de Charcot tipo 3a de Brodsky tratados quirúrgicamente mediante artrodesis de tobillo con clavo centromedular retrógrado bloqueado, del 1o de Enero de 2010 al 31 de Agosto de 2015. Se analizaron 16 pacientes. En el preoperatorio la media de la escala de AOFAS fue de 35.0 ± 5.2 puntos. Un seguimiento postoperatorio de cuatro años con un mínimo de siete meses. En el postoperatorio la escala de AOFAS mostró un incremento de 40 puntos hacia la mejoría (p = 0.0001). La técnica revisada logra la estabilización ósea, resultando en un pie con apoyo plantígrado que disminuye la aparición de úlceras crónicas y mejora el desarrollo en las actividades de la vida cotidiana.

Abstract: Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living. Material and methods: Design: observational, prospective, transversal, descriptive. Sample: patients diagnosed with Charcot neuropathy type 3a of Brodsky. Surgically treated by ankle arthrodesis with an intramedullary blocked nail, from January 2010 to August 2015. Results: 16 patients were analyzed. Preoperative AOFAS score was 35.0 ± 5.2 points. Postoperative follow-up period of 4 years to 7 months. Postoperative AOFAS scale showed an improvement of 40 points (p = 0.0001). Conclusions: The proposed treatment allows bone stabilization, resulting in a full foot plantar support and decreases the occurrence of chronic ulcers that are difficult to treat, and is an alternative method that avoids lead to amputation.
