RESUMO
Background: Evidence concerning the complex foot trauma, especially its definitive management, is scarce. Soft tissue envelope sequalae are the primary parameters that delay or make internal fixation implausible. Stability conferred by external fixators makes them a reasonable initial treatment choice. Although AO or circular fixators can be applied around the foot, this can involve a learning curve and substantial costs, especially for the circular fixator. There is little evidence as to how well external fixators work as a definite method of fixation in patients where progression to internal fixation cannot be made. Methods: We prospectively evaluated 10 adult patients with severe and complex foot trauma who were consecutively treated at our clinic. Initial reduction and stabilization were performed with an external fixator that was initially conceived for distal radius fractures, applied during the initial procedure and mantained throughout the treatment. Results: Fracture healing was obtained in all 10 cases, and both internal and external column length was restored. One of the patients developed chronic osteomyelitis. At the 1-year follow-up visit, these patients averaged 45.6 points in the physical and 44.8 points on the mental status sections of the 12-Item Short Form Health Survey (SF-12). The Foot Function Index findings for pain, disability, and daily activities limitations were 33.3, 39, and 41.5, respectively, which suggest moderate residual impairment. Conclusion: In this relatively small case series of complex foot trauma, we found that the use of simple external fixation as definitive treatment worked reasonably well. Level of Evidence: Level III, prospective cohort study.
RESUMO
Background: Combining osteotomies and soft tissue procedures is believed to reduce sesamoids in their anatomical position and maintain long-term correction when treating hallux valgus deformity. This study determines if a radiologic association exists between a radiolucent sign and a full percutaneous adductor tendon release (PATR), including a cadaveric study and a consecutive case series. Another aim was to determine the intra- and interobserver reliability of these observations. Methods: A prospective observational study was made between 2018 and 2019. First, a PATR was done on cadaveric specimens and, after the procedures, dissected to correlate what was seen fluoroscopically. The clinical group included 39 feet that presented mild-to-moderate HV deformity and were treated with percutaneous osteotomies associated with PATR. Results: Observers 1 and 2 saw a radioscopic radiolucent sign in 100% of cadavers and the patient population. They also observed a triangle-shaped image with an incidence of 75%, which we have named the "triangle sign." Conclusion: The triangle sign may be helpful in the intraoperative confirmation of PATR and latero-plantar capsule release using this percutaneous technique. Level of Evidence: Level II, development of diagnostic criteria.
RESUMO
Background: Hindfoot coronal alignment is an important factor in the assessment of patients with many different foot and ankle complaints. A number of clinical and radiographic techniques have been described to measure hindfoot coronal alignment, but none of them are widely accepted. The purpose of the present study was to assess the correlation between clinical and radiographic hindfoot alignment measures and to evaluate the reproducibility of each. Methods: We evaluated 85 patients with foot and/or ankle symptoms. Hindfoot clinical alignment was measured from photographs. Each patient was placed at a distance of 1 m from the observer, with both feet placed parallel. Four photographs were taken, at a height of 40 cm: a posterior view of both lower limbs including knees, a posterior view focalized on the studied hindfoot, an anterior view of the foot, and the last view of the medial aspect of the foot. Radiographic alignment was quantified on long axial view radiographs. Patients were lying over the film cassette with a focus distance of 1 m and the beam pointed to the ankle joint. The inclination angle of the beam was 45 degrees to the floor. Measurements were independently made by 2 observers, who were asked to classify pictures into 3 categories: varus, neutral, and valgus. Radiographic measurements were made using the angle measurement tool on the radiograph viewer. The intraclass correlation coefficients (ICCs) and the 95% confidence interval (CI) of the ICC were used to quantify the inter- and intraobserver reliability for clinical assessment. Radiographic parameters were correlated by calculating the Pearson correlation coefficient (r). Results: The intraobserver ICC for clinical analysis was good for both observers, while the interobserver ICC was moderate for both measurements. Regarding radiographic assessment, there was significant intra- and interobserver reliability. The correlation between both methods was weak for both observers. Conclusions: We found only weak intra- and interobserver correlations between the clinical and radiographic assessment of hindfoot coronal alignment. It is therefore necessary to complement the clinical evaluation of hindfoot alignment with an objective measurement method such as a long axial view radiograph. Further studies comparing different measurement methods need to be performed to establish the most objective evaluation. Level of Evidence: Level III, diagnostic study.
RESUMO
Objetivo: Describir los resultados radiográficos y funcionales, y las complicaciones de la osteosíntesis de fracturas de calcáneo mediante el abordaje del seno del tarso. Materiales y Métodos: Se evaluaron 54 fracturas articulares de calcáneo desplazadas en 50 pacientes con radiografías de pie, de frente y de perfil, y tomografía computarizada preoperatorias. Se tomaron radiografías de pie, de frente y de perfil sin carga en el posoperatorio inmediato y con carga a las semanas 6 y 12, y al final del seguimiento. Se midió el ángulo de Böhler y se cuantificó el grado de artrosis subastragalina y calcaneocuboidea. Se determinó el puntaje de la AOFAS y se registraron las complicaciones de la herida, las lesiones neurológicas y la necesidad de cirugías adicionales, como retiro del material de osteosíntesis y artrodesis subastragalina. Resultados: El seguimiento fue de 30.8 meses. La serie estaba formada por 8 mujeres y 42 hombres, con una edad de 39.40 ± 14 años (rango 18-65). Cuarenta fracturas eran Sanders tipo II, 13 tipo III y 1 tipo IV. El puntaje de la AOFAS fue: excelente (12 casos), bueno (25 casos), regular (12 casos) y malo (5 casos). El ángulo de Böhler preoperatorio era de 10,8 ± 10,4° y 30,77 ± 8,24° al final del seguimiento (p <0,00001). El 3,7% tuvo complicaciones menores de la herida y el 5,6%, complicaciones mayores. Conclusión: El abordaje del seno del tarso permite una reducción aceptable con resultados buenos y excelentes en la mayoría de los pacientes y escasas complicaciones de partes blandas. Nivel de Evidencia: IV
Objective: To describe functional and radiographic outcomes, and complications of osteosynthesis in calcaneus fractures with the sinus tarsi approach. Materials and Methods: 54 displaced articular calcaneus fractures in 50 patients were assessed through preoperative foot radiographs (anteroposterior and lateral) and computerized tomography. AP and lateral radiographs were obtained in the immediate postoperative period (without weightbearing), after 6 and 12 weeks (with weightbearing), and at the end of follow-up, measuring the Böhler angle and quantifying the degree of subtalar and calcaneocuboid osteoarthritis. The AOFAS score was determined, registering wound complications, neurological injuries and necessary additional surgeries -such as osteosynthesis and subtalar arthrodesis hardware removal. Results: Follow-up time was 30.8 months. The series consisted in 8 women and 42 men. The patients' average age was 39.40±14 years (18-65). There were 40 Sanders type II, 13 type III, and 1 type IV fractures. The AOFAS score was excellent (12 patients), good (25), regular (12), and poor (5). The Böhler angle was 10.8°±10.4° before surgery, and 30.77°±8.24° at the end of follow-up (p<0.00001). 3.7% of the patients presented minor wound complications, while 5.6% presented major wound complications. Conclusion: The sinus tarsi approach allows for acceptable reduction with good and excellent outcomes in most patients, coupled with few soft-tissue complications. Level of Evidence: IV

During the last 2 decades, there was an increasing interest in mini-invasive procedures for hallux valgus correction. In this scenario the Bösch technique appears to be a reproducible distal metatarsal osteotomy (DMO) to achieve a proper correction. Our DMO variant, called BC, was planned to combine the stability and predictability of the chevron osteotomy, with the power of correction, low surgical time and mini-invasive approach of the Bösch-SERI technique. The purpose of this investigation is to describe the surgical technique and report the results of this modified procedure at a minimum 2-year follow-up. Sixty-three patients who underwent the BC technique for mild and moderate hallux valgus were prospectively evaluated. Mean follow-up was 36.5 (range 23.4-59.8) months, the mean American Orthopedic Foot and Ankle Society score improved from a median of 47.4 points preoperatively to a median of 88 points postoperatively (p < .05). First MTPJ ROM did not change from preoperative period (mean 32.5°) to the postoperative period (mean 31.8°) (p > .65). All osteotomies went on to bony healing in the 6-week follow-up visit. Fifty-two (82%) of patients were either very satisfied or satisfied with the procedure (p < .05). With our numbers, BC osteotomy is shown to be a technique that can treat both mild and moderate deformities, achieving correction that is maintained over the follow-up evaluated, with a 24 relatively simple procedure and short operative time.

Objetivo: Describir los factores asociados con niveles de dolor mas severo en una cohorte de pacientes con fascitis plantar. El objetivo secundario fue analizar cuales de estos factores estaban asociados con niveles mas altos de mejoria clinica luego del tratamiento conservador. Materiales y Métodos: Se evaluo a una cohorte prospectiva de pacientes con diagnostico de fascitis plantar. Cada participante completo una escala ordinal visual de dolor (del 1 al 10) para dolor del primer paso y dolor al final del dia y encuestas FFI-R (Foot Function Index-Revised). Tambien se realizo una evaluacion demografica. La dorsiflexion de la articulacion del tobillo, el rango de movilidad de la primera articulacion metatarsofalangica, la rigidez del gastrocnemio y el angulo popliteo tambien se evaluaron de manera estandar. Resultados: Se incluyo a 214 pacientes. El 64% eran hombres (118 pacientes), la media de la edad era de 49.67 anos (DE 13.16) y el indice de masa corporal promedio, de 28,53 (DE 5,18). En el analisis multivariado, se observo que el riesgo de un puntaje ≥8 en la escala de dolor aumento cuando el paciente refirio estar de pie por mas de 6 h (OR 1,17; p = 0,03; IC95% 1,02-1,35). El riesgo de un puntaje >8 fue mayor cuando el grado de dorsiflexion del tobillo fue <0° (OR 1,20; p = 0,03; IC95% 1,02-1,41). Conclusión: Nuestros hallazgos apoyan indirectamente la hipotesis de que la dorsiflexion limitada del tobillo juega un papel como factor de riesgo asociado a un puntaje ≥8 en la escala de dolor, en los casos de fascitis plantar.

Objective: The main purpose of our study was to describe the factors associated with more severe pain levels in a cohort of patients with plantar fasciitis (PF). The secondary purpose of this study was to determine which of these factors were associated with higher levels of clinical improvement after conservative therapy. Materials and Methods: We conducted a prospective study in a cohort of patients with PF. Each participant completed an ordinal pain scale (1-10) for first-step pain and end-of-day pain, and Foot Function Index-Revised (FFI-R) surveys at enrollment. Also, patient demographics were evaluated. The ankle joint dorsiflexion, the range of motion (ROM) for the first metatarsophalangeal joint (MTPJ), the gastrocnemius tightness, and the popliteal angle were evaluated through standard tests. Results: Our study included 214 participants, of which 64% (118 patients) were males, the average age was 49.67 years (SD 13.16) and the average BMI was 28.53 (SD 5.18). The multivariate analysis showed that the risk of having a Visual Analog Scale (VAS) score ≥8 increased when the patient reported standing for more than 6 hours (OR=1.17; P=0.03; CI95%: 1.02-1.359). The risk of a >8-VAS score was higher when the level of ankle dorsiflexion was <0 (OR=1.20; P=0.03; CI95%: 1.02-1.41). Conclusion: Our findings indirectly support the hypothesis that limited ankle dorsiflexion ROM plays a role as a risk factor associated with VAS scores ≥8 in PF patients. Level of Evidence: IV

BACKGROUND: In high-risk patients, common prophylaxis may be insufficient to prevent thromboembolic events after orthopaedic procedures. In this scenario, a retrievable vena cava filter (VCF) could be considered as an alternative, although it's use remains controversial. Therefore, we asked: (1) what is the overall mechanical complication rate associated with the use of retrievable VCFs in orthopaedic surgery?, (2) what is the association with thromboembolic disease (TED) recurrence, post-thrombotic syndrome and/or major bleeding according to different surgical characteristics?, (3) What is the overall mortality rate attributed to VCF use? METHODS: We retrospectively analyzed a cohort of 68 patients who underwent orthopaedic surgery with a previous diagnosis of TED, in whom a retrievable VCF was placed. Permanent filters were excluded. We studied the filter's mechanical complications and considered as possible outcomes death and 3 hematologic complications: TED recurrence, post-thrombotic syndrome and major bleeding. To estimate association with risk factors, we subclassified surgeries into 5 groups: 1, arthroplasty/non-arthroplasty; 2, primary/revision; 3, elective/urgent; 4, oncologic/non-oncologic; 5, preoperative/postoperative filter. RESULTS: Mechanical complications were 16% and required a filter revision. Sixty-four percent of the revised VCFs developed a mechanical failure and could not be retrieved. Overall prevalence of TED recurrence, post-thrombotic syndrome and hemorrhage was 33%, 15% and 4.5%, respectively. Spinal surgeries were a risk factor for developing TED recurrences. Only 4% of patients died of a TED recurrence. CONCLUSIONS: Orthopaedic procedures had a high risk of mechanical and hematologic complications after using a retrievable VCF. However, mortality was low due to these complications.
