RESUMO
Time spent in the operating room is valuable to both surgeons and patients. One of the biggest rate-limiting factors when it comes to arthrodesis procedures of the foot and ankle is cartilage removal and joint preparation. Power instrumentation in joint preparation provides an avenue to decrease joint preparation time, thus decreasing operating room time and costs. Arthrodesis of 47 joints (n) from 27 patients were included. Power rasp joint preparation in 26 joints was compared to traditional osteotome and curette joint preparation in 21 joints in both time (seconds), cost (total operating room time cost per minute), and union rate. The overall mean joint preparation time using power rasp for the subtalar joint was 268.3 seconds, talonavicular joint 212.3 seconds, calcaneocuboid joint 142.6 seconds, 1st TMT 107.2 seconds. Mean joint preparation time using traditional method for subtalar joint 509.8 seconds, talonavicular joint 393.0 seconds, calcaneocuboid joint 400.0 seconds, 1st TMT 319.6 seconds. Mean cost of joint preparation using power rasp for subtalar joint $165.47, talonavicular joint $130.89, calcaneocuboid joint $87.94, 1st TMT $66.11. Mean cost of joint preparation using traditional techniques for subtalar joint $314.34, talonavicular joint $242.35, calcaneocuboid joint $246.67, 1st TMT $197.33. Overall union rate was 98% (1 asymptomatic non-union). Increasing efficiency in the operating room is vital to every surgeon's practice. Power rasp joint preparation is a viable option to increase efficiency and decrease operative time, this study shows no statistically significant differences in union rate, with comparable rates to existing literature.

BACKGROUND: The purpose of this study was to evaluate the prevalence of foot involvement in psoriatic arthritis and to describe its different clinical and radiological features. PATIENTS AND METHODS: We conducted a cross sectional study including 40 patients with psoriatic arthritis over a period of 12 months. Anamnesis, clinical examination of feet, podoscopic examination, X-rays of feet and heels, and ultrasound in B mode and power Doppler mode were done for each patient. RESULTS: Foot involvement was found in 95% of cases. It was symptomatic in 70% and inaugural of the disease in 20% of cases. The hindfoot and the forefoot were the sites most affected (77.5% and 47.5% respectively). The involvement of the midfoot was rarer (25%). Dactylitis was found in 17.5% and deformities of forefoot were found in 22.5% of cases. Antalgic gait was noted in 17.5% and static disorders of foot at podoscopic examination were identified in 35% of cases. Feet dermatological manifestations were found in 45% of cases. Diagnosis of different rheumatological manifestations was based on clinical findings and caracteristic radiological images on X-rays. We demonstrate he sensitivity of ultrasound in the detection and the diagnosis of different foot lesions including enthesitis, synovitis and tenosynovitis, dactylitis, bone erosions and psoriatic nail dystrophy.

Injury to the tarsometatarsal joint (TMT) results in instability throughout the midfoot that does not often improve with conservative management. If instability is identified, surgical intervention is frequently recommended, either open reduction and internal fixation (ORIF) or primary arthrodesis (PA). These 2 treatment options have been compared in the literature multiple times, often reporting similar outcomes. Due to this, as well as the need for subsequent hardware removal after ORIF has led many surgeons towards PA at the index surgery. Concern for nonunion is a leading concern with surgeons who advocate instead for ORIF. The purpose of this study is to review patients who underwent PA and observe nonunion rates. Nonunion at the TMT has been previously studied, but only in the chronic setting. We performed a retrospective study of 34 patients who had PA in the management of an acute Lisfranc injury. The average age in our study was 43.9 years old (range 19-72, SD 17.4) with an average follow-up of 9.4 months (range 4-33, SD 6.2). Radiographs were evaluated for signs of nonunion at regular postoperative intervals. Within the patients included in the study, a total of 71 TMT joints were fused. Overall successful fusion rate was 95.8% at an average of 7.9 weeks (range 6-12, SD 1.4) postoperatively. Individual nonunion rates at the first, second, and third TMT were 0%, 1.4% and 2.8% respectively. Our study demonstrates that primary arthrodesis provides a predictable outcome with low nonunion rates in the management of acute Lisfranc injury.

OBJECTIVES: Hallux valgus is associated with tarsometatarsal arthritis; its pathophysiology remains unknown. Therefore, we aimed to elucidate the relationship between arthritis of the second and third tarsometatarsal joints and incongruity of the first tarsometatarsal joint in the sagittal plane. METHODS: Forty-three patients (64 feet) with hallux valgus who underwent surgery at University Hospital Kyoto Prefectural University of Medicine were included and divided into two groups: control (without second and third tarsometatarsal joint degeneration) and osteoarthritis (with second and third tarsometatarsal joint degeneration). Intergroup comparisons of the incongruity of the first tarsometatarsal joint in the sagittal plane, age, body mass index, hallux valgus angle, first-second intermetatarsal angle, metatarsus adductus angle, Meary's angle, and calcaneal pitch angle were performed. RESULTS: The proportion of patients with incongruity of the first tarsometatarsal joint was significantly higher in the osteoarthritis group than in the control group. Logistic regression analysis identified incongruity of the first tarsometatarsal joint and metatarsus adductus angle as significant related factors for arthritis of the second and third tarsometatarsal joints. CONCLUSIONS: Incongruity of the first tarsometatarsal joint in the sagittal plane was involved in the development of arthritis of the second and third tarsometatarsal joints in patients with hallux valgus.

Ankle osteoarthritis does not only led to lower ankle power generation, but also results in compensatory gait mechanics at the hip and Chopart joints. Much of previous work explored the relative work distribution after total ankle replacement (TAR) either across the lower extremity joints where the foot was modelled as a single rigid unit or across the intrinsic foot joints without considering the more proximal lower limb joints. Therefore, this study aims, for the first time, to combine 3D kinetic lower limb and foot models together to assess changes in the relative joint work distribution across the foot and lower limb joints during level walking before and after patients undergo TAR. We included both patients and healthy control subjects. All patients underwent a three-dimensional gait analysis before and after surgery. Kinetic lower limb and multi-segment foot models were used to quantify all inter-segmental joint works and their relative contributions to the total lower limb work. Patients demonstrated a significant increase in the relative ankle positive joint work contribution and a significant decrease in the relative Chopart positive joint work contribution after TAR. Furthermore, there exists a large effect toward decreases in the relative contribution of the hip negative joint work after TAR. In conclusion, this study seems to corroborate the theoretical rationale that TAR reduces the compensatory strategy in the Chopart and hip joints in patients suffering from end-stage ankle osteoarthritis.

Tarsometatarsal joint injuries can be painful and debilitating and are most commonly due to direct or indirect trauma. Posttraumatic arthritis is a well-known long-term complication, with incidence as high as 58%. Conservative treatment options include shoe modifications, orthotic inserts, topical or oral anti-inflammatories, and intra-articular corticosteroid injections. There are various joint prep and fixation techniques reported in the literature, many with positive clinical and radiographic outcomes. This article discusses nonoperative and operative management of posttraumatic tarsometatarsal joint arthritis, reviews available literature, and includes the authors' tips and techniques.

BACKGROUND: Historically, most Lisfranc injuries have been considered to be unstable and treated with surgical intervention. However, with better access to cross-sectional imaging, stable injury patterns are starting to be recognised. The aims of the current study were to perform a systematic review of outcomes of Lisfranc injuries treated non-operatively. METHODS: A literature review was performed of studies reporting nonoperative management of Lisfranc injuries (PROSPERO registered and following PRISMA guidelines). Following exclusions, 8 papers were identified: 1 prospective and 7 retrospective studies. A total of 220 patients were studied with a mean age of 39.8 years and a mean follow-up of 4.3 years. Outcomes included function, displacement, and rates of surgery. RESULTS: High heterogeneity was observed with variable outcomes. Four papers reported good outcomes, with adjusted functional scores ranging from 82.6 to 100 (out of 100). However, one study reported late displacement in 54 % of patients. Rates of secondary osteoarthritis ranged from 5 % to 38 %. Rates of surgical intervention were as high as 56 %. Several studies compared operative to non-operative treatment, reporting superior outcomes with surgery. Those injuries with no displacement on CT, measured at the medial cuneiform-second metatarsal had the best outcomes. CONCLUSION: Reported outcomes following nonoperative treatment of Lisfranc injuries vary widely, including high rates of conversion to surgery. In contrast, some studies have reported excellent functional outcomes. CT seems to be an important diagnostic tool in defining a stable injury. Due to limited data and lack of a clear definition of a stable injury or treatment protocol, prospective research is needed to determine which Lisfranc injuries can be safely treated nonoperatively.

A stable medial column is important to the normal function of the foot and ankle. Medial column instability and forefoot varus can result in compensatory hindfoot motion leading to stress along the medial soft-tissue structures. Medial column stabilization should therefore be considered when (1) forefoot varus deformity is identified following hindfoot realignment; (2) pronounced medial column instability is present, even in the absence of forefoot varus; and (3) when degenerative changes are present within the medial column articulations. Common surgical procedures include arthrodesis of the talonavicular joint, naviculocuneiform joint, and first tarsometatarsal joint, as well as osteotomy of the medial cuneiform (Cotton osteotomy).

The adult-acquired flatfoot is a complex multiplanar deformity that requires the foot and ankle surgeon to balance soft tissue, correct hindfoot valgus, and address instability of the medial column. The naviculocuneiform joint is historically underappreciated in regard to its involvement in medial column instability relative to the talonavicular and tarsometatarsal joints. Proper clinical and radiographic evaluation of the medial column, specifically evaluating for deformity at each medial column joint, will allow the surgeon to ensure correction of deformity and decrease the recurrence of instability or failure of the reconstruction.

BACKGROUND: Recently, temporary bridge plate fixation has gained popularity in the treatment of unstable Lisfranc injuries. The technique aims to reduce the risk of posttraumatic osteoarthritis, and after plate removal, the goal is to regain joint mobility. Here we explore marker-based radiostereometric analysis (RSA) to measure motion in the 1st tarsometatarsal (TMT) joint and asses the radiological outcome in patients treated with this surgical technique. METHOD: Ten patients with an unstable Lisfranc injury were included. All were treated with a dorsal bridge plate over the 1st TMT joint and primary arthrodesis of the 2nd and 3rd TMT joints. The plate was removed four months postoperatively. Non- and weight-bearing RSA images were obtained one and five years postinjury to assess joint mobility and signs of osteoarthritis. RESULTS: Detectable 1st TMT joint motion was observed in 2/10 patients after one year, and 6/9 patients after five years. At the final follow-up, mean 1st TMT dorsiflexion was 2.0°. Radiologically, the incidence of posttraumatic osteoarthritis was present in 4/10 patients after one year, and 5/9 patients after five years. All patients had observed TMT joint stability throughout the follow-up period. CONCLUSION: Preservation of joint motion can be achieved with a temporary bridge plate fixation over the 1st TMT joint. TYPE OF STUDY/LEVEL OF EVIDENCE: Prospective cohort study/Therapeutically level IV.

INTRODUCTION: Instability/collapse of the medial column has been associated with many conditions, particularly progressive collapsing foot deformity (PCFD), hallux valgus (HV), and midfoot arthritis (MA). Restoration of first ray length and sagittal plane alignment to restore the foot tripod is essential when treating these deformities. This study aimed to assess early results, healing, and complication rate of a distraction dorsal opening plantarflexion wedge allograft first tarsometatarsal joint fusion (LapiCotton Procedure) in patients with collapse/instability of the medial column. METHODS: In this prospective cohort study, we included PCFD, HV, and MA patients that underwent a LapiCotton procedure. Fusion site healing was defined by > 50% bone bridging in both interfaces between allograft wedge and host bone using weight-bearing computed tomography (WBCT) after 3 months. First ray collapse radiographic correction and minor and major complications (deep dehiscence, deep infection, and reoperation) were assessed. RESULTS: A total of 22 patients (22 feet) were included (11 PCFD, 6 MA, and 5 of HV patients). Mean follow-up was 5.9 months (range 3-12) and median allograft size was 8 mm (range 5-19 mm). Bone healing was observed in 91% of cases. Two minor complications (9%, both superficial dehiscence) and one major complication (4.5%, deep infection) were observed. Statistically significant improvement of the sagittal plane talus-first metatarsal angle was observed, with mean improvement of 9.4° (95% CI 6.7-12.1°; p < 0.0001). CONCLUSION: In this prospective cohort study of 22 patients treated with the LapiCotton procedure for medial longitudinal arch collapse/instability, we observed a low complication rate (9% minor, 4.5% major), high healing rate after 3 months (91%), one clinically stable radiographic non-union (4.5%) and one unstable non-union (4.5%) needing reoperation. Our results demonstrate promising initial results for LapiCotton technique in treating collapse of the medial longitudinal arch in patients with PCFD, MA and HV deformities. Long-term results are needed to confirm these promising results. LEVEL OF EVIDENCE: Level II, prospective cohort study.

Lisfranc injuries are complicated injuries of the tarsometatarsal joint with high rates of sequelae. Both anatomy and injury of the Lisfranc joint are variably documented. Descriptions of these injuries and their associated structures vary greatly. The most injured structures are those of the Lisfranc joint complex, which involves the medial cuneiform, second and third metatarsals, and the dorsal, interosseous, and plantar Lisfranc ligaments. This study sought to examine morphology of the Lisfranc joint in cadavers. Twenty-two embalmed cadaveric feet were dissected (13 male, 9 female, 80.3 years ± 14.03) to isolate the bones and ligaments of the Lisfranc joint complex. The dorsal, interosseous, and plantar Lisfranc ligaments were present in each specimen. Each ligament was measured and morphology noted. The dissected dorsal Lisfranc ligament had consistent morphology (mean = 10.8 mm ± 1.79). The interosseous Lisfranc ligament had a consistent path, but 11/17 of specimens possessed a connection to the plantar Lisfranc ligament. The plantar Lisfranc ligament demonstrated wide variability with a Y-variant (n = 3) and a fan-shaped variant (n = 14). Ligament thickness was greatest in the interosseous Lisfranc ligament (mean = 13.74 ± 3.08) and least in the dorsal Lisfranc ligament (mean = 1.36 ± 0.42). While the objective of defining joint and ligament morphology was achieved, further questions were raised. Variations of the interosseous and plantar Lisfranc ligament may play a role in susceptibility to joint injury, and arthritic changes to the joints examined raise questions regarding the prevalence of arthritis in the uninjured Lisfranc joint.

Las luxaciones del escafoides aisladas y sin fractura son poco frecuentes. Por lo general, se presentan asociadas a fracturas del escafoides o a diversos patrones de lesión de la columna lateral. Presentamos el caso de un paciente con luxación medial y plantar del hueso navicular y fractura conminuta del proceso anterior del calcáneo y subluxación calcaneocuboidea. En el Servicio de Urgencia, se procedió a la reducción cerrada y la estabilización con agujas de Kirschner y, como tratamiento diferido, se colocaron placas en puente astragalonaviculo-cuneiforme y calcaneocuboidea de 2,0 mm, en forma transitoria, y el material de osteosíntesis se retiró a los 5 meses. El puntaje de la escala de la AOFAS fue excelente al año de seguimiento. Conclusiones: Es necesario llegar a un diagnóstico adecuado descartando lesiones de la columna lateral y reducir esta lesión en la atención de urgencia. La estabilización con placas en puente es una opción válida que podría evitar la pérdida de la reducción que se observa al retirar los clavos de Kirschner y permite una carga precoz.

Isolated navicular dislocations are unusual. They are frequently associated with navicular fractures or diverse patterns of lateral column injuries. We report a case of a patient with medial and plantar navicular dislocation with a comminuted intra-articular fracture of the anterior process of the calcaneus and associated subluxation at the calcaneocuboid joint. The patient underwent closed reduction and Kirschner wire stabilization in the Emergency Service. As part of the deferred treatment, talonavicular-cuneiform and calcaneocuboid 2.0 mm bridge plates were temporarily placed and osteosynthesis material was removed 5 months later. The AO-FAS score was excellent in the one-year follow-up. Conclusion: An accurate diagnosis, ruling out lateral column injuries, should be done in the Emergency Service. Bridge plate stabilization is a valid option to prevent loss of reduction, which is observed when removing Kirschner wires, allowing early weight-bearing. Level of Evidence: IV

Introducción: La lesión del ligamento calcaneonavicular ha sido descrita como una de las causas de la deformidad en el pie plano del adulto. El objetivo de este artículo es describir portales modificados para el diagnóstico y la reparación endoscópica de las lesiones del fascículo superomedial del ligamento calcaneonavicular y evaluar la seguridad de los portales utilizados. Materiales y Métodos:Se llevó a cabo un estudio cadavérico con seis preparados reproduciendo una lesión del fascículo superomedial del ligamento calcaneonavicular con una punta de corte de radiofrecuencia y la posterior reparación endoscópica. Se crearon dos portales modificados para el abordaje. Luego se procedió a la disección anatómica para evaluar la seguridad de los portales en relación con las estructuras anatómicas. El primer portal se realiza inmediatamente proximal a una línea trazada desde la punta del maléolo medial dirigida al centro del talón, el segundo portal se emplaza 0,5 cm proximal a la inserción del tendón tibial posterior en el escafoides por transiluminación. Si es necesario, se coloca un portal accesorio inmediatamente dorsal al tendón tibial posterior a mitad de camino entre los dos portales antes descritos. Resultados:En todos los casos, fue posible la reparación del ligamento con el procedimiento endoscópico. En la disección anatómica de los portales, se observó una distancia promedio a las estructuras vasculonerviosas de 11,83 mm del portal proximal y de 9,66 mm del portal distal. Conclusión: Los portales modificados son seguros y permiten la visualización directa del haz superomedial del ligamento calcaneonavicular y su reparación endoscópica. Nivel de Evidencia: IV
Introduction: Calcaneonavicular ligament injury has been described as a cause of adult flat foot deformity. The objective of this study is to describe modified portals for the diagnosis and treatment of injuries to the superomedial bundle of the calcaneonavicular ligament and to evaluate the safety of the portals used. Materials and Methods: We performed a cadaveric specimen study on 6 feet, where we reproduced a lesion of the superomedial bundle of the calcaneonavicular ligament with a radiofrequency ablation device and repaired it endoscopically. Two modified portals were created for the approach and an anatomical dissection was performed to assess the safety of the portals in relation to the anatomical structures. The first portal was placed immediately proximal to a line drawn from the tip of the medial malleolus toward the center of the heel; the second portal was placed 0.5 cm proximal to the posterior tibial tendon insertion into the navicular bone, guided by transillumination. If needed, an accessory portal was placed halfway between the two previously described portals immediately dorsal to the posterior tibial tendon. Results:In all cases, ligament repair was achieved with the endoscopic procedure. In the anatomical dissection of the portals, we observed an average distance of 11.83 mm from the proximal portal and 9.66 mm from the distal portal to neurovascular structures. Conclusion:Modified portals are safe and allow direct visualization of the superomedial bundle of the calcaneonavicular ligament to perform endoscopic repair. Level of Evidence: IV

Abstract Objective This study proposes the Niza box, a device created to reduce interpretive errors among professionals and facilitate the correct positioning of structures by standardizing orthopedic radiography of the foot in anteroposterior, loaded, and Saltzman views. Methods Descriptive study based on material collected at an Orthopedics Ambulatory from a tertiary service in a large Brazilian city. The X-ray device was a Lotus X, model HF 500 M, 500 milliamperes and 125 kilovolts capacity, 100 cm focus-film distance, and 24 × 30 cm radiographic chassis. Device controls were set at 100 mA, 5 mA/sec, and 60 kilovolts, depending on the variable size of the foot. The same team of previously trained radiography technicians performed the tests under the authors' supervision. The chassis were positioned in three specific Niza box spaces per the proposed incidence. Data from 50 images from people between 18 and 70 years old were analyzed. Results Radiographs taken using the proposed device usually had a satisfactory quality, allowing correct identification of the anatomical elements of the foot and ankle and angular reconstruction. Small image variations due to foot size were acceptable and expected, allowing radiograph standardization. Conclusion The Niza box is a good method for minimizing interference and avoiding radiographic interpretation errors, providing quality and agility to the examination, and reducing cost and unnecessary repetitions. It is an innovative, low-cost device made of recyclable and biodegradable material.

AIM: To determine from a patient perspective what improves the quality of care and patient satisfaction during the treatment and recovery process of Lisfranc fractures and to reveal possible points for improvement in this process. METHODS: We performed a qualitative study based on semi-structured interviews with patients treated for a Lisfranc fracture-dislocation in the Netherlands with either open reduction and internal fixation or primary arthrodesis, until data saturation was reached, focusing on the quality of care during treatment and recovery, from a patient perspective. RESULTS: Data saturation was reached after interviewing 10 patients. The main themes emerging from the analysis were expectation management regarding the recovery period; communication with and between health care providers; information provided during consultations; and support during the recovery period. Participants expressed a need for improved provision of information about the different treatment options, the different kinds of pain that can arise, the expected duration of the recovery period, education on strong pain killers, likelihood of a second surgery, risks of osteoarthritis, risks of the surgery itself, allied health care and patient experiences. Participants mentioned the importance of good allied health care and a preference for starting allied health care as soon as possible. Insoles and compression socks were also appreciated by various participants. Finally, multiple patients saw a positive attitude on the part of the health care providers towards the recovery period as a key factor in recovery. CONCLUSION: This study found that patients value more tailored approaches to the pre-and post-operative care program, more guidance regarding allied health care (physiotherapy), and a broader scope of available references and information for patients, both oral (during consultations and in informative videos) and written, such as brochures or evidence-based web pages and mobile platforms, which may be offered during consultations or when being discharged from the hospital.

BACKGROUND: Compensatory motion of foot joints in hallux rigidus (HR) are not fully known. This study aimed to clarify the kinematic compensation within the foot and to detect whether this affects plantar pressure distribution. METHODS: Gait characteristics were assessed in 16 patients (16 feet) with HR and compared with 15 healthy controls (30 feet) with three-dimensional gait analysis by using the multi-segment Oxford Foot Model, measuring spatio-temporal parameters, joint kinematics and plantar pressure. RESULTS: HR subjects showed less hallux plantar flexion during midstance and less hallux dorsiflexion during push-off, while increased forefoot supination was detected during push-off. No significant differences in plantar pressure were detected. Step length was significantly smaller in HR subjects, while gait velocity was comparable between groups. CONCLUSIONS: HR significantly affects sagittal hallux motion, and the forefoot compensates by an increased supination during push-off. Despite this kinematic compensatory mechanism, no significant differences in plantar loading were detected.

Coronal plane hindfoot malalignment produces abnormal compensatory forces within the midfoot and forefoot. The primary aim of this study is to compare radiographic hindfoot alignment in patients with a midfoot Charcot event, and identify patterns associated with breakdown. A retrospective review of 43 patients (48 limbs) with midfoot Charcot neuroarthropathy were compared between the coronal hindfoot alignments and Charcot joint involvement. Coronal hindfoot alignment was classified as neutral (n = 15), valgus (n = 16), and varus (n = 17) utilizing the Saltzman hindfoot alignment radiograph. Charcot joint breakdown was classified as isolated tarsometatarsal joint (n = 8), combination of tarsometatarsal and naviculocuneiform joints (n = 22), and midtarsal joints including talonavicular and calcaneocuboid joints (n = 18). Patients exhibiting varus hindfoot alignment had 5.8 times greater risk of breakdown at the tarsometatarsal and naviculocuneiform joints (odds ratio 5.8, 95% confidence interval 1.7-22.9, p < .01). Hindfoot varus induces external rotation of the talus, resulting in compensation through the naviculocuneiform and tarsometatarsal joint, which correlates with our findings of a 6-fold increase in naviculocuneiform and tarsometatarsal joint collapse. Patients exhibiting valgus hindfoot alignment had 27 times greater risk of breakdown at the midtarsal joint (odds ratio 27.0; 95% confidence interval 5.6-207.0, p < .01). Hindfoot valgus induces internal rotation of the talonavicular joint, which correlates with our findings of a 27-fold increase in midtarsal joint breakdown. Varus and valgus hindfoot alignment are associated with different midfoot injury patterns, which may have implications in surgical management and allow for focused surveillance in neuropathic patients presenting with early-stage clinical findings consistent with Charcot neuroarthropathy.
