ABSTRACT

Introducción: La enfermedad de Caffey es una patología ósea inflamatoria, rara, autolimitada, casi exclusiva de lactantes. Objetivos: Jerarquizar el abordaje diagnóstico de una patología poco frecuente. Caso clínico: 4 meses 22 días, varón, consulta por irritabilidad y edema de miembro inferior izquierdo de 4 días de evolución. Sin traumatismos ni fiebre. Examen físico: edema indurado en tercio medio e inferior de pierna izquierda, no rubor ni calor local. Dolor a la palpación de cara anterior y lateral de tibia y peroné. Limitación funcional, no resaltos óseos. Radiografía: engrosamiento del periostio en tibia y peroné a nivel diafisario. Hemograma: Glóbulos blancos 15.380 KU/L, Hemoglobina 10,8 g/dL, Plaquetas 816.400 10/ul, proteína C reactiva 13,90 mg/dl. Con planteo de probable infección osteoarticular se inicia clindamicina ( gentamicina e ingresa a cuidados moderados. Dada la persistencia de edema e irritabilidad, al quinto día se solicita resonancia magnética: hallazgos sugerentes de un probable proceso inflamatorio- infeccioso de partes blandas con compromiso óseo. Completa 14 días de clindamicina y 7 días de gentamicina intravenosa, hemocultivo negativo. Persiste con edema, irritabilidad y dolor. A los 21 días, se revalora la presentación clínica-imagenológica, se plantea enfermedad de Caffey. Se inicia anti-inflamatorio con buena evolución. Conclusiones: La enfermedad de Caffey es una colagenopatía rara, que afecta lactantes. El diagnóstico es clínico - radiológico (irritabilidad, tumefacción de partes blandas y alteraciones radiológicas). El pronóstico a largo plazo suele ser favorable. Es importante considerar el diagnóstico en lactantes que se presentan con esta sintomatología para evitar retrasos diagnósticos e instauración de tratamientos innecesarios.


Introduction: Caffey's disease is a rare disease that is reported almost exclusively in infants. Objective: Describe the case of a rare pathology, prioritizing the diagnostic approach. Clinical case: 4 month -old, healthy male. Consultation due to irritability and edema of the left lower limb for 4 days. No trauma or fever. Physical examination: indurated edema in the left leg, no redness or local heat. Pain on palpation of the anterior and lateral aspect of the tibia and fibula. Functional limitation, no bony protusions. Leg x-ray: thickening of the periosteum in the tibia and fibula at the diaphyseal level. Hemogram: White Blood Cells 15,380 KU/L Hemoglobin: 10.8 g/dL. Platelets: 816,400 10/ul, C-reactive protein: 13.90 mg/dl. He was admitted with a suggestion of probable osteoarticular infection. Clindamycin ( gentamicin is started. Given the persistence of edema and irritability despite treatment, on the fifth day an MRI was requested: findings suggestive of a probable inflammatory-infectious process of soft tissues with bone involvement. Completed 14 days of clindamycin and 7 days of intravenous gentamicin, blood culture negative. It persists with edema, irritability and pain. After 21 days, the clinical-imaging presentation was reassessed and Caffey's disease was considered. Anti-inflammatory begins with good evolution. Conclusions: Caffey's disease is a rare collagenopathy, that affects infants. The diagnosis is clinical - radiological (irritability, soft tissue swelling and radiological alterations). The long-term prognosis is usually favorable. It is important to consider the diagnosis in infants who present with these symptoms to avoid diagnostic delays and initiation of unnecessary treatments.

ABSTRACT

Introducción: El autoinjerto vascular de peroné se presenta como una muy buena opción en la reconstrucción de grandes defectos óseos en huesos largos gracias a sus características estructurales y propiedades biológicas. Materiales y Métodos: Se realizó un estudio observacional descriptivo y retrospectivo que incluyó a todos los pacientes operados con un injerto vascular de peroné aislado o asociado a injerto estructural (técnica de Capanna) desde el 1 de enero de 2014 hasta el 1 de enero de 2021 en nuestro hospital. Resultados: Se realizaron 26 cirugías mediante un injerto vascular de peroné; en 8 de ellas, se utilizó el colgajo vascularizado de peroné para la reconstrucción del defecto óseo en hueso largo. El tamaño medio del defecto era de 7,7 cm. El origen del defecto era postraumático en 5 casos y tumoral en el resto. Se consiguió la consolidación completa en todos los pacientes. Los resultados clínicos y funcionales en las escalas de valoración fueron mejores en pacientes operados en el miembro inferior. Conclusiones: El uso de un colgajo vascularizado de peroné asociado o no a aloinjerto estructural es una estrategia útil en la reconstrucción de grandes defectos óseos (≥5 cm), independientemente de la causa de la lesión; la supervivencia del injerto y la función son buenas, con una tasa de complicaciones aceptable. Nivel de Evidencia: IV


Background: Given its biological and structural qualities, vascular fibular autograft is a good option for the reconstruction of large defects in long bones. Materials and Methods: A descriptive and retrospective observational study was conducted. We included all cases of patients who underwent surgery in our hospital between January 1, 2014, and January 1, 2021, and who had a vascular fibula autograft either standalone or in combination with a structural graft (Capanna technique). Results:There were 26 documented vascular fibula autograft procedures. Eight of the procedures involved the reconstruction of a long bone defect. The bone defect was an average of 7.7 cm in length. In five of the cases, the origin of the bone defect was post-traumatic, and in the remaining cases, it was tumoral. In all cases, complete consolidation was achieved. Surgical procedures performed on the lower extremities yielded better clinical and functional outcomes. Conclusions:Vascular fibula autograft either on its own or in combination with a structural graft, as described in the Capanna technique, is an excellent alternative for the reconstruction of bone defects ≥ 5 cm. Radiological, clinical and functional outcomes are good, with an acceptable rate of complications. Level of Evidence: IV

ABSTRACT

Jaw defects caused by various reasons often seriously affect appearance and function. The goal of the treatment of oral and maxillofacial tumors should include the cure of the tumor and the restoration of premorbid function. The development of microsurgery and digital surgery technology has promoted the development of jaw reconstruction with vascularized free bone flap. Good appearance and improved predictability could be obtained with the help of preope-rative visual design. How to rehabilitate occlusal function on the reconstructed jaw and improve the quality of life of patients has become an important research direction. This article discusses the challenge of jaw reconstruction, the selection of vascularized bone flap, the choice of implant timing, the treatment of peri-implant soft tissue, and the influence of radiotherapy on implants after jaw reconstruction.

ABSTRACT

OBJECTIVE@#To investigate the difference in sensitivity between X-ray and three-dimensional reconstruction of computed tomography (3D-CT) for the diagnosis of distal fibular avulsion fracture, and the radiographic presentation of the ossicle.@*METHODS@#From January to October 2018, 92 patients with distal fibular avulsion fracture were visited for surgical treatment in Department of Sports Medicine, Peking University Third Hospital, and 60 cases were finally enrolled according to the inclusion and exclusion criteria. Intraoperative detection was regarded as the gold standard, and the diagnostic sensitivity of preoperative ankle X-ray and 3D-CT for the distal fibular avulsion fractures was statistically determined. The ossicle maximum diameter as well as the degree of its displacement were also measured. On 3D-CT, the distance from the ossicle center point to the anterior fibular tuberosity (a), the distance to the fibular tip (b), and the a/b value was used to present the ossicle displacement.@*RESULTS@#Among the 60 patients, 36 and the 52 patients were correctly detected by X-ray and 3D-CT, respectively, and the sensitivities was 60.0% and 86.7%, respectively (P=0.004). The mean diameter of the ossicle on X-ray and 3D-CT was (9.2±3.9) mm and (10.5±3.2) mm, respectively. The mean distance from the ossicle center to the anterior fibular tuberosity (a) was (17.5±3.6) mm and the mean distance to the fibular tip (b) was (17.4±4.8) mm, with mean a/b values of 1.1±0.7. The intraclass correlation coefficients (ICC) for each measurement ranged from 0.891-0.998 with a high degree of consistency.@*CONCLUSION@#Compared with X-ray, 3D-CT has higher sensitivity in diagnosing distal fibular avulsion fractures, can help clinicians evaluate ossicle's location and choose surgical methods, and is recommended to be performed in patients with suspected distal fibula avulsion fractures in clinical practice.

ABSTRACT

OBJECTIVE@#To establish the finite element model of varus-type ankle arthritis and to implement the finite element mechanical analysis of different correction models for tibial anterior surface angle (TAS) in supramalleolar osteotomy.@*METHODS@#A female patient with left varus-type ankle arthritis (Takakura stage Ⅱ, TAS 78°) was taken as the study object. Based on the CT data, the three-dimensional model of varus-type ankle arthritis (TAS 78°) and different TAS correction models [normal (TAS 89°), 5° valgus (TAS 94°), and 10° valgus (TAS 99°)] were created by software Mimics 21.0, Geomagic Wrap 2021, Solidworks 2017, and Workbench 17.0. The 290 N vertical downward force was applied to the upper surface of the tibia and 60 N vertical downward force to the upper surface of the fibula. Von Mises stress distribution and stress peak were calculated.@*RESULTS@#The finite element model of normal TAS was basically consistent with biomechanics of the foot. According to biomechanical analysis, the maximum stress of the varus model appeared in the medial tibiotalar joint surface and the medial part of the top tibiotalar joint surface. The stress distribution of talofibular joint surface and the lateral part of the top tibiotalar joint surface were uniform. In the normal model, the stress distributions of the talofibular joint surface and the tibiotalar joint surface were uniform, and no obvious stress concentration was observed. The maximum stress in the 5° valgus model appeared at the posterior part of the talofibular joint surface and the lateral part of the top tibiotalar joint surface. The stress distribution of medial tibiotalar joint surface was uniform. The maximum stress of the 10° valgus model appeared at the posterior part of the talofibular joint surface and the lateral part of the top tibiotalar joint surface. The stress on the medial tibiotalar joint surface increased.@*CONCLUSION@#With the increase of valgus, the stress of ankle joint gradually shift outwards, and the stress concentration tends to appear. There was no obvious obstruction of fibula with 10° TAS correction. However, when TAS correction exceeds 10° and continues to increase, the obstruction effect of fibula becomes increasingly significant.

ABSTRACT

ANTECEDENTES El peroné flotante tras un traumatismo de alta energía es una entidad muy poco frecuente. Este es el primer reporte de caso asociado a luxación del tendón bicipital. OBJETIVO Presentar un caso de peroné flotante tras luxación divergente de tobillo asociado a luxación peronea proximal. MATERIALES Y MÉTODOS Mujer de 17 añ que, tras accidente de tráfico, sufrió caída y presentó dolor y deformidad del tobillo izquierdo, junto con dolor e impotencia funcional de la rodilla ipsilateral. En las radiografías, se apreció una luxación pura divergente del tobillo izquierdo de tipo IV. Se realizó reducción cerrada en urgencias. El estudio se complementó con una resonancia magnética que mostró una rotura completa de la sindesmosis y del ligamento deltoideo, así como una fractura no desplazada de la meseta tibial externa, junto con un desgarro de la cápsula tibioperonea proximal y desprendimiento completo del ligamento lateral externo y del tendón bicipital desde su inserción en la cabeza del peroné. Se realizó reanclaje de la sindesmosis y del ligamento deltoideo, así como del ligamento lateral externo y del tendón bicipital mediante anclajes óseos metálicos y reducción de peroné tanto proximal como distalmente, mediante sistema de sutura tipo botón. Se inmovilizó con férula cruropédica por cuatro semanas. RESULTADOS La paciente presentó recuperación completa de la fuerza a los cinco meses de seguimiento, con movilidad completa del tobillo y de la rodilla. CONCLUSIÓN El peroné flotante es muy poco frecuente; sólo se ha descrito un caso en la literatura. Implica la disrupción de la articulación tibioperonea proximal y distal, lo que puede provocar inestabilidad en la rodilla y en el tobillo. Por tanto, ante un traumatismo de alta energía en el tobillo, es necesaria la exploración minuciosa de la rodilla ipsilateral.


BACKGROUND Floating fibula after high-energy trauma is a very uncommon entity. The present is the first report of a case associated with avulsion of the bicipital tendon. PURPOSE To present a case of floating fibula after divergent ankle dislocation associated with proximal peroneal dislocation. MATERIALS AND METHODOS A 17-year-old woman who fell after a traffic accident and presented pain and deformity of the left ankle with pain and functional impotence in the ipsilateral knee. The radiographs showed a pure divergent type-IV left-ankle dislocation. Closed reduction was performed in the emergency room. The study was complemented with a magnetic resonance imaging scan which showed complete rupture of the syndesmosis and the deltoid ligament, as well as a non-displaced fracture of the external tibial plateau together with a tear of the proximal tibiofibular capsule and complete detachment of the external lateral ligament and bicipital tendon from its insertion in the peroneal head. The syndesmosis and deltoid ligament were reanchored, as well as the external lateral ligament and the bicipital tendon, using metallic bone anchors and fibula reduction both proximally and distally, using a suture-button system. The patient was immobilized with a long-leg splint for four weeks. RESULTS The patient presented complete recovery of strength at five months of follow-up. CONCLUSSION Floating fibula is a rare entity, with only one case described in the literature. It involves a disruption of the proximal and distal tibiofibular joint, which can lead to knee and ankle instability. Therefore, in cases of high-energy trauma to the ankle, a careful examination of the ipsilateral knee is necessary.

ABSTRACT

Proximal tibiofibular instability is a rare condition for which treatment is poorly codified. A 21-year-old patient, a leisure sportswoman, presented a post-traumatic anterolateral instability of the proximal tibiofibular articulation without cartilage lesion. We propose an original surgical technique based on a review of the literature that combines an anatomical ligamentoplasty of the proximal tibiofibular joint and a proximal fibular diaphyseal osteotomy to reduce the distal tibiofibular mechanical stresses. This original technique allows a favorable evolution with recovery of professional and sports activities at 6 months.

ABSTRACT

El acortamiento y la rotación del peroné son las deformidades más frecuentemente encontradas cuando se presentan maluniones postraumáticas del tobillo resultando en ensanchamiento de la mortaja e inestabilidad astragalina, con consecuentes cambios artrósicos. Los pacientes acuden por presentar dolor y limitación en sus actividades diarias y deportivas. En el presente estudio retrospectivo se hace una evaluación de los resultados clínicos y radiológicos de 9 pacientes que se sometieron a tratamiento quirúrgico posterior a maluniones de fracturas de peroné, en los cuales se realizaron osteotomías de alargamiento y desrotación para reconstrucción del tobillo, en la Unidad de Cirugía de Pie y Tobillo del Hospital Universitario de Caracas, entre junio de 2014 y agosto del 2019. Se realizaron mediciones radiológicas pre y postoperatorias de los ángulos de inclinación astragalina, talocrural y bimaleolar, y se reportaron los cambios degenerativos articulares. Para la evaluación clínica y funcional se aplicó la Escala Análoga Visual (VAS) para el dolor, y la Escala AOFAS de retropié, evidenciándose mejoría en cuanto a dolor, función y alineación. El objetivo del tratamiento fue restituir la longitud inicial del peroné, mediante osteototomías oblicuas en el sitio de la fractura anterior, o transversas suprasindesmales, con lo cual también se corrige la alineación del astrágalo, y de esta manera prevenir o disminuir los síntomas y signos inherentes a degeneración articular progresiva(AU)


The shortening and rotation of the fibula are the most frequent deformities found when post-traumatic ankle malunions occur, resulting in widening of the mortise and talus instability, with consequent arthritic changes. Patients have pain and limitation in their daily activities and sports. In the present retrospective study, an evaluation of the clinical and radiological results of 9 patients who underwent surgical treatment after fibular fracture malunions was performed, in which osteotomies of lengthening and de-rotation were performed for reconstruction of the ankle, in the Unit of Foot and Ankle Surgery at the University Hospital of Caracas, between June 2014 and August 2019. Pre and postoperative radiological measurements of the astragaline, talocrural and bimaleolar inclination angles were performed, and degenerative joint changes were reported. For the clinical and functional evaluation, the Visual Analog Scale (VAS) was applied for pain, and the AOFAS Hindfoot Scale, evidencing improvement in pain, function, and alignment. The objective of the treatment was to restore the initial length of the fibula by means of oblique osteotomies at the site of the previous fracture or suprasindesmal transverse osteotomy, which also corrects the alignment of the talus and thus prevents or decreases the symptoms and signs inherent to joint progressive degeneration(AU)

ABSTRACT

La inestabilidad de la articulación tibioperonea proximal puede presentarse con una luxación, con escasos síntomas laterales de la rodilla, dolor, malestar e incomodidad durante distintas actividades o síntomas relacionados con la irritación del nervio peroneo común. Un preciso diagnóstico prequirúrgico es imperativo, así como el tratamiento conservador con inmovilización y kinesiología por cuatro a seis semanas. En la población adolescente, el planeamiento prequirúrgico puede ser dificultoso por la presencia de los cartílagos abiertos, por lo tanto, se debe tomar precaución en la realización de los túneles y en la colocación de implantes en relación con la fisis abierta. El objetivo del siguiente trabajo es presentar el caso de un niño de once años con inestabilidad tibioperonea proximal recurrente, además mostrar detalles de la técnica quirúrgica, protocolo postoperatorio y sus excelentes resultados


Instability of the proximal tibiofibular joint (PTFJ) can present as dislocations, vague symptoms of lateral knee pain, discomfort during activity, or symptoms related to irritation of the common peroneal nerve. An accurate preoperative diagnosis is imperative and should include a trial of taping of the PTFJ for a 4- to 6-week time frame before surgical reconstruction is indicated. In the adolescent population, surgical planning can be complicated by the presence of open physes; therefore, caution must be taken to avoid drilling through or placing screw fixation across the physes. Potential complications include growth arrest and limb length discrepancy. Therefore, the purpose of this case report is to describe the surgical technique for addressing PTFJ instability in adolescent patients. The aim of this case report is to present a case of instability of the proximal tibiofibular joint (PTFJ) treated surgically in an eleven-year-old male soccer player, focused on technical tips, strict rehab protocol with excellent results

ABSTRACT

Introducción El estándar de manejo para las fracturas del peroné distal es la reducción abierta más fijación interna con placa y tornillos (bloqueados o no), sin embargo, existen complicaciones asociadas a este tipo de intervención. En pacientes ancianos con mala calidad de tejidos blandos o en quienes presentan traumas de alta energía como etiología de las fracturas en el tobillo, la tasa de complicaciones previamente mencionadas aumenta, por lo que el manejo de las fracturas de peroné distal con tornillos percutáneos representa una alternativa con menor riesgo de complicaciones y con desenlaces similares al manejo convencional. Materiales y métodos Se realiza una serie de casos de pacientes con fractura de peroné manejados de forma percutánea. Se obtuvo una muestra de 17 pacientes por un año, a quienes se les realizó seguimiento sobre tasa de consolidación, funcionalidad y complicaciones postoperatorias. Resultados Diez (62,5%) fueron hombres, con una media de edad de 59 años (rango entre 24 y 90). El 100% fueron secundarios a traumas de alta energía, 10 (62,5%) fueron izquierdas, 14 (87,5%) se clasificaron como Weber B y 7 casos (56,25%) se presentaron concomitantemente con fracturas abiertas. Conclusiones Con el fin de evitar complicaciones, se debe considerar este abordaje en pacientes con comorbilidades, de edad avanzada o con tejidos blandos lesionados severamente o de mala calidad


Background The standard management for distal fibula fractures is open reduction plus internal fixation with plate and screws (blocked or not), however, there are complications associated with this type of intervention. In elderly patients with poor soft tissue quality or in those with high-energy trauma as the etiology of ankle fractures, the rate of previously mentioned complications increases, so that the management of distal fibula fractures with percutaneous screws represents a alternative with lower risk of complications and similar outcomes to conventional management. Methods A series of cases of patients with fibula fracture managed percutaneously was carried out. A sample of 17 patients was obtained for one year, who were followed up on consolidation rate, functionality, and postoperative complications. Results 10 (62.5%) were men, with a mean age of 59 years (range between 24 and 90). 100% were secondary to high-energy trauma, 10 (62.5%) were left, 14 (87.5%) were classified as Weber B and 7 cases (56.25%) presented concomitantly with open fractures. Discussion In order to avoid complications, this approach should be considered in patients with comorbidities, the elderly, or those with severely injured or poor-quality soft tissues.

ABSTRACT

La concepción original del mecanostato como un regulador de la rigidez estructural ósea orientado a mantener un determinado 'factor de seguridad' en todos los esqueletos parece no corresponder por igual a cualquier hueso y para cualquier tipo de estímulo. Hemos descubierto que la estructura cortical diafisaria del peroné humano manifiesta un comportamiento ambiguo del sistema, referido al uso del pie. La diáfisis peronea, además de ser insensible al desuso, se rigidiza, como sería de esperar, por entrenamientos en disciplinas deportivas que rotan o revierten el pie (hockey, fútbol, rugby); pero, llamativamente, se flexibiliza en su mitad proximal por entrenamiento en carrera larga, que optimiza el rendimiento del salto que acompaña a cada paso. La referida rigidización robustecería la región peronea de inserción de los músculos que rotan o revierten el pie, favoreciendo la locomoción sobre terrenos irregulares o 'gambeteando', propia de especies predadoras como los leopardos. La 'inesperada' flexibilización proximal, pese a reducir la resistencia a la fractura por flexión lateral (poco frecuente en el hombre), favorecería la absorción elástica de la energía contráctil de la musculatura inserta, optimizando el rendimiento del salto al correr, condición vital para especies presas como las gacelas. La falta de analogía de estas respuestas de la estructura peronea a distintos entrenamientos, incompatible con el mantenimiento de un factor de seguridad, sugiere su vinculación preferencial con la optimización de aptitudes esqueléticas con valor selectivo. Esto ampliaría el espectro regulatorio del mecanostato a propiedades esqueléticas 'vitales', más allá del control de la integridad ósea. Su manifestación en el hombre, ajena a connotaciones selectivas (quizá resultante del mantenimiento de genes ancestrales), permitiría proponer la indicación de ejercicios orientados en direcciones preferenciales a este respecto, especialmente cuando estas coincidieran con las de las fuerzas que podrían fracturar al hueso. (AU)


The original notion of the mechanostat as a regulator of bone structural rigidity oriented to maintain a certain 'safety factor' in all skeletons does not seem to correspond equally to every bone and for any type of stimulus. We have discovered that the diaphyseal cortical structure of the human fibula shows an ambiguous behavior of the system, with reference to the use of the foot. The peroneal shaft, in addition to being insensitive to disuse, becomes stiffened, as might be expected, by training in sport disciplines that involve rotating or reversing the foot (hockey, soccer, rugby); but, remarkably, it becomes more flexible in its proximal half by long-distance running training, which optimizes the performance of the jump that accompanies each step. The stiffening would strengthen the peroneal region of insertion of the muscles that rotate or reverse the foot, favoring locomotion on uneven terrain or 'dribbling', typical of predatory species such as leopards. The 'unexpected' proximal flexibilization, despite reducing the resistance to lateral flexion fracture (rare in human), would favor the elastic absorption of contractile energy from the inserted muscles, optimizing jumping performance when running, a vital condition for prey species such as gazelles. The lack of analogy of these responses of the peroneal structure to different training, incompatible with the maintenance of a safety factor, suggests its preferential link with the optimization of skeletal aptitudes with selective value. This would expand the regulatory spectrum of the mechanostat to 'vital' skeletal properties, beyond the control of bone integrity. Its manifestation in humans, oblivious to selective connotations (perhaps resulting from the maintenance of ancestral genes), would make it possible to propose the indication of exercises oriented in preferential directions, especially when they coincide with the direction of the forces that could fracture the bone.

ABSTRACT

OBJECTIVE@#To investigate the short-term clinical effect of double channel decompression and bone grafting through the greater trochanter combined with allograft fibula propping in the treatment of osteonecrosis of femoral head (ONFH).@*METHODS@#Twenty two patients (23 hips) with osteonecrosis of the femoral head were included from November 2017 to February 2019. According to Association Research Cirulation Osseous(ARCO) staging, there were 13 hips at stageⅡgroup, aged from 20 to 48 years old with an average of(32.5±8.5)years old;10 hips at stageⅢgroup, aged from 18 to 45 years old with an average of(32.7±8.6) years old. A single approach through the greater trochanterwas used for decompression, bone grafting and fibula support. Harris scoring system was used to evaluate the function of hip joint before and after implantation, and the anteroposterior and lateral X-ray films of hip joint were taken at 3, 6, 12 and 18 months after implantation to observe and analyze the progress of femoral head necrosis and regeneration.@*RESULTS@#All patients were followed up, and the duration ranged from 12 to 18 months with an average of (14.6±2.1) months. Harris score of stageⅡand stageⅢpatients increased from 73.2± 5.5 and 66.5±3.4 to 87.6±8.7(@*CONCLUSION@#The effect of double trochanteric decompression and bone grafting combined with fibular allograft propping in the treatment of early and middle stage avascular necrosis of the femoral head is good, especially suitable for young and middle aged patients with ARCOⅡstage avascular necrosis of the femoral head.

ABSTRACT

OBJECTIVE@#To measure anatomical data of calcaneofibular ligament (CFL), relevant data of CFL attachment to provide an anatomical basis for CFL reconstruction.@*METHODS@#Twenty-seven adult ankle specimens were selected, including 11 males and 16 females, aged from 22 to 71 years old with an average of (41.6±17.2) years old;9 cases on the left side and 18 cases on the right side. The specimens reserved at least 20 cm above ankle joint and a complete foot, and exclude deformities, fractures, incomplete development and degenerative lesions. CFL was performed detailed anatomical observation, morphological parameters of CFL was measured, and coordinates of fibula side and calcaneal side of CFL in the coordinate axis were measured. The distance between fibula insertion of CFL and fibula tip, distance between calcaneal insertion of CFL and lateral calcaneal nodule, and Angle between CFL and long axis of fibula were also measured.@*RESULTS@#In these 27 specimens, CFL cases were all single bundles and the length of CFL was (32.83 ± 8.19) mm. The center point of fibula attachment in CFL was(2.87± 1.21) mm proximal with a coefficient of variation of 42.16% and (2.08±1.34) mm anteriorly with a coefficient of variation of 64.42%. The center point of calcaneal attachment region of CFL was located on coordinate axis on the distal end (15.32±5.33) mm, with a coefficient of variation of 34.79%, and the posterior part (6.38±2.15) mm, with a coefficient of variation of 33.86%. The distance between center point of fibula attachment and fibula tip was (4.81±0.82) mm. The distance between center point of calcaneal attachment area of CFL and lateral calcaneal nodules was(17.25±3.12) mm. Angle between CFL and fibula axis is (43 ±18)° .@*CONCLUSION@#According to anatomical studies, we could locate the fibula and calcaneal attachment of CFL by anatomical markers around ankle joint. However, the location of CFL attachment has a large variation, and the anatomical characteristics need to be considered in anatomical reconstruction.

ABSTRACT

Objective: To analyse the quality of life of patients receiving repair of bone defect with folded fibula flap after removal of mandibular ameloblastoma. Methods: The case data of 39 patients with ameloblastoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2013 to April 2016 were retrospectively analysed, including 21 males and 18 females, from 18 to 58 years old. 3D printing and digital technology were used in flap preparation before surgery in all patients. The folded fibular flaps were used to repair mandibular defects and the implants were placed between 6-9 months after surgery. The short form-36 health survey questionnaire (SF-36) and the university of Washington quality of life questionnaire (UW-QOL) were applied to evaluate the quality of life of patients before surgery and at 6 months and 24 months after surgery. The higher the score, the better the condition. SPSS 20.0 was adopted for statistical analysis. Results: The SF-36 survey showed that the mean score of body role before surgery (72.4±11.7) was significantly higher than that at 6 months after surgery (39.6±11.1, t=23.580, P<0.05) or that at 24 months after surgery (59.8±6.4, t=8.358, P<0.001). Compared with the preoperative mean scores of Physical Pain (73.0±11.0), General Health (73.4±10.4) and Health Changes (79.2±3.9) before surgery, the mean scores Physical Pain (53.1±7.7), General Health (53.5±7.5) and Health Changes (63.9±11.7) at 6 months after surgery were decreased significantly respectively (t=13.068, 13.756 and 10.880, respectively, all P<0.05), but the mean scores Physical Pain (78.8±14.0), General Health (80.9±12.6) and Health Changes (84.4±4.6) at 24 months after surgery were increased significantly respectively (t=-2.904, -4.027 and -7.586, respectively, all P<0.05), with significant differences in the mean scores of Physical Pain, General Health and Health Changes between 6 and 24 months after surgery (t=-14.241, -16.490, -14.294, respectively, all P<0.001). The UW-QOL survey showed that the mean scores of chewing, language and taste functions decreased at 6 months after surgery (53.1±6.7, 53.0±7.7 and 62.2±9.9, respectively), but improved at 24 months after surgery (67.9±3.9, 63.9±2.9 and 68.4±11.1, respectively), with statistically significant difference (t=-16.765, -11.675 and 2.498, respectively, all P<0.001). Conclusion: The application of folded fibula flaps to repair bone defects after sugery of mandibular ameloblastoma can better meet the needs of language and chewing functions and improve the quality of life of patients.

ABSTRACT

RESUMEN Introducción: Las fracturas abiertas del tercio distal de tibia o pilón son poco frecuentes, en nuestro medio se producen por traumas de alta energía como los accidentes de tránsito, y pueden ser de distintos grados según su envergadura. Entre las complicaciones frecuentes están la seudoartrosis, deformidades y artritis postraumática. Cuando el dolor es refractario a los analgésicos están indicadas las artrodesis. Objetivo: Presentar los resultados del tratamiento realizado en un paciente con seudoartrosis distal de tibia y artritis postraumática del tobillo, dolorosa, con gran lesión de partes blandas, por lo que fue imposible realizar los procedimientos quirúrgicos habituales. Presentación del caso: Se realizó artrodesis de las articulaciones tibio-peronea-astragalina-calcánea, mediante un injerto libre del peroné autólogo, compresión, y estabilización con un fijador externo RALCA®; se asoció un campo electromagnético pulsátil para acelerar la formación del callo óseo y disminuir el dolor posquirúrgico. Durante dos años se le hizo seguimiento. Conclusiones: Se logró el objetivo del tratamiento al fusionar la articulación tibiotarsiana, comenzar el apoyo precoz y su capacidad funcional. Los resultados demuestran además los beneficios de la compresión realizada con los fijadores externos en las artrodesis; el uso del campo electromagnético asociado aceleró la osteogénesis, se consiguió la consolidación ósea, la estabilización, disminuyó el edema y el dolor, además la reincorporación del paciente a la sociedad. No se encontró en la bibliografía revisada otra técnica quirúrgica similar(AU)


ABSTRACT Introduction: Open fractures of the distal third of the tibia or pilon are rare, in our environment they are caused by high-energy traumas such as traffic accidents, and can be of different degrees depending on their size. Common complications include nonunion, deformities, and post-traumatic arthritis. When pain is refractory to analgesics, arthrodesis is indicated. Objective: To report the results of the treatment carried out in a patient with distal tibial pseudoarthrosis and post-traumatic arthritis of the ankle, painful, with a large soft tissue injury, which made it impossible to perform the usual surgical procedures. Case report: Arthrodesis of the tibiofibular-talar-calcaneal joints was performed, using a free graft of the autologous fibula, compression, and stabilization with a RALCA® external fixator. A pulsatile electromagnetic field was associated to accelerate bone callus formation and reduce postoperative pain. This patient was followed up for two years. Conclusions: The treatment objective was achieved by fusing the tibiotarsal joint, by starting early support and functional capacity. The results also prove the benefits of compression performed with external fixators in arthrodesis. The use of the associated electromagnetic field accelerated osteogenesis, bone consolidation and stabilization were achieved, edema and pain decreased, as well as the patient's reincorporation into society. No other similar surgical technique was found in the reviewed literature(AU)

ABSTRACT

RESUMEN Cronobacter sakazakii es una bacteria Gram negativa que pertenece a un grupo emergente de patógenos oportunistas de la familia de los Enterococos, que causa infecciones nosocomiales. Afecta típicamente a los recién nacidos de bajo peso; puede causar graves infecciones como meningitis, sepsis o enterocolitis necrotizante, potencialmente mortales, aunque la gran mayoría de las infecciones se producen en pacientes ancianos, en los que son mucho más leves. Se reporta el primer caso confirmado de infección de herida quirúrgica en España causada por C. sakazakii en un adulto inmunocompetente(AU)


ABSTRACT Cronobacter sakazakii is a Gram negative bacterium that belongs to an emerging group of opportunistic pathogens of the Enterococci family, which causes nosocomial infections. It typically affects low birth weight newborns. It can cause serious infections such as meningitis, sepsis, or life-threatening necrotizing enterocolitis, although the vast majority of infections occur in elderly patients, where they are much milder. We report the first confirmed case of surgical wound infection in Spain, caused by C. sakazakii in an immunocompetent adult(AU)

ABSTRACT

La expansión modeladora de la geometría cortical de un hueso inducida por su entorno mecánico podría ser difícil de modificar por estímulos ulteriores con diferente direccionalidad. Este estudio, que por primera vez combina datos tomográficos del peroné (pQCT) y dinamométricos de la musculatura peronea lateral, intenta demostrar que, en individuos jóvenes no entrenados, el entrenamiento en fútbol produce cambios geométricos peroneos expansivos, similares a los del rugby, que podrían interferir en los efectos de un entrenamiento ulterior direccionalmente diferente (carrera larga). Confirmando la hipótesis, los resultados indican, con evidencias originales, 1) la relevancia creciente del uso del pie (rotación externa y eversión provocadas por los peroneos laterales) para la determinación de la geometría peronea (incremento del desarrollo de los indicadores de masa y de diseño óseos), evidenciada por la secuencia creciente de efectos: carrera < fútbol < rugby; 2) la predominancia de esos efectos sobre el desarrollo centro-proximal del peroné para resistir a la flexión lateral, y en la región distal para resistir el buckling (principal sitio y causa de fractura del hueso) y 3.) la relevancia de la anticipación de esos efectos para interferir en la manifestación de los cambios producidos por un entrenamiento ulterior (carrera), cuando los del primero (fútbol) afectan la modelación cortical de modo expansivo. Esta última deducción demuestra, en forma inédita, que un cambio modelatorio expansivo tempranamente inducido sobre la estructura cortical ósea 'delimitaría el terreno'para la manifestación de cualquier otro efecto ulterior por estímulos de distinta direccionalidad. (AU)


The modeling-dependent, geometrical expansion of cortical bone induced by the mechanical environment could be hard to modify by subsequent stimulations with a different directionality. The current study aimed to demonstrate that in young, untrained individuals, training in soccer or rugby enhances the geometric properties of the fibula cortical shell in such a way that the geometrical changes could interfere on the effects of a second training in which the loads are induced in a different direction, e.g. long-distance running. The original findings reported herein confirm our hypothesis and support 1) The relevance of the use of the foot (external rotation and eversion produced by peroneus muscles) to determine fibula geometry (improved development of indicators of bone mass and design) as evidenced by the increasing nature of the effects induced by running < soccer < rugby trainings; 2) The predominance of those effects on the ability of the fibula to resist lateral bending in the centralproximal region (insertion of peroneus muscles), and to resist buckling in the distal region (the main cause and site of the most frequent bone fractures), and 3) The interaction of the effects of a previous training with those of a subsequent training with a different orientation of the loads when the former induced a modeling-dependent expansion of the cortex. Our results support the proposed hypothesis with original arguments by showing that a first, expansive effect induced on cortical bone modeling would set the stage the manifestation of any subsequent effect derived from mechanical stimuli.

ABSTRACT

El ligamento tibiofibular anterior suele presentar un fascículo distal independiente de la banda principal, denominado fascículo distal del ligamento tibiofibular anterior (FD-LTFA). Este discurre oblicuamente, cubriendo sus fibras más inferiores la zona anterolateral de la articulación talocrural. Su presencia se asocia a pellizcamiento del tobillo en esta zona, el cual puede producir un desgaste cartilaginoso de la cara anterolateral de la tróclea talar. El propósito de este estudio fue determinar la presencia y biometría del FD-LTFA, y su relación con la troclea talar en tobillos de un grupo de individuos Chilenos. En este estudio se utilizaron 30 miembros inferiores de cadáveres de individuos adultos. Se evaluó en el fascículo distal: Ancho en la inserción tibial, ancho en la inserción fibular, longitud del margen superior, longitud del margen inferior y el espesor. Se determinó si había contacto talar por parte del FD-LTFA y se observó desgaste articular en la superficie del domo talar, a nivel de la región de contacto del mencionado ligamento. El FD-LTFA fue encontrado en un 76,7 % de los casos, su anchura a nivel del sitio de fijación tibial fue de 5,30 mm (± 1,4) y a nivel fibular 4,43 mm (± 0,85). En cuanto a su longitud en el margen superior fue de 14,26 mm (± 3,66) y a nivel del margen inferior fue de 16,74 mm (± 2,91). Su espesor fue de 2,1 mm (± 0,36). En las 23 muestras de tobillo con presencia del FD-LTFA, hubo contacto talar en el 100 % de los casos y desgaste articular en esta zona en 3 de ellas (13,04 %). Los datos biométricos aportados por este estudio complementarán el conocimiento anatómico del FD-LTFA en la población Chilena.


The anterior tibiofibular ligament usually presents an independent distal fascicle of the main band, denominated distal fascicle of the anterior tibiofibular ligament (DF-ATiFL). Which obliquely passes, covering its most inferior fiber to the anterolateral corner of the talocrural articulation. Its presence is associated with the anterolateral impingement of the ankle in this area, which can produce cartilage wear of the anterolateral surface of the talar trochlea. The purpose of this study was to determine the presence and biometry of DF-ATiFL and its relation with the talar trochlea on the ankles of a group of Chilean individuals. Thirty inferior members were used in this study, all from adult individuals. It was evaluated: Width of the tibial insertion, width of the fibular insertion, length of the top margin, length of the bottom margin, and the thickness. It was determined whether there was talar contact by the distal fascicle of the anterior tibiofibular ligament. Also, it was observed the articular wear on the surface of the talar dome, at the level of the contact region of the distal fascicle of the anterior tibiofibular ligament. The DFATiFL was found in 76.7 % of the cases, its width at the level of the place of tibial fixation was 5.30 mm (± 1.40), and at the fibular level 4.43 mm (± 0.85). Regarding its length on the top margin was 14.26 mm (± 3.66), and at the bottom, the margin level was 16.74 mm (± 2.91). Its thickness was 2.1 mm (± 0.36). In the 23 ankles samples with the presence of DF-ATiFL, there was talar contact in 100 % of the cases and articular wear in this area in 3 of them (13.04 %). The biometric data contributed by this study will supplement the anatomical knowledge of the distal fascicle of the anterior tibiofibular ligament on the Chilean population.

ABSTRACT

Abstract Objective The literature entails various intramedullary and extramedullary methods for distal fibula fracture fixation; with no consensus yet over the ideal method of fixation. We have retrospectively analyzed the results of using a twisted and contoured 3.5 mm locking compression plate (LCP) as a posterior buttress plate. Methods Of the 62 cases with ankle fractures managed at our institute by the senior author from 1st January 2012 to 31st December 2015, 41 patients met our inclusion criteria (Danis-Weber types B and C). Results All 41 distal fibular fractures healed uneventfully, at a mean of 10.4 weeks (8-14 weeks) (Figs. 6, 7, 8 to 9) with no complications. The mean American Orthopaedic Foot & Ankle Society (AOFAS) score was 92.6 (86-100) at a mean follow-up of 31.5 months (14-61 months). Conclusions We have achieved excellent clinical and radiological outcomes using a twisted 3.5 mm LCP as a posterior buttress by combining the advantages of posterior antiglide plating and lateral LCP.
