Factores etiopatogénicos y tratamiento de la enfermedad de Müller-Weiss / Etiopathogenic factors and treatment of Müller-Weiss disease

Antecedentes y objetivo: La enfermedad de Müller-Weiss (EMW) es una anomalía poco frecuente del escafoides tarsiano. Maceira y Rochera propusieron la teoría etiopatogénica más comúnmente aceptada, en la que estarían implicados factores displásicos, mecánicos y ambientales socioeconómicos. Se pretende describir las características clínicas y sociodemográficas de los pacientes de nuestro entorno con EMW, corroborar su asociación con los factores socioeconómicos descritos previamente, estimar la influencia de otros factores descritos en el desarrollo de la EMW, así como describir el tratamiento realizado. Materiales y métodos: Estudio retrospectivo de 60 pacientes diagnosticados de EMW en 2 hospitales terciarios de Valencia (España) entre los años 2010 y 2021. Resultados: Se incluyeron 60 pacientes, 21 (35,0%) hombres y 39 (65,0%) mujeres. En 29 (47,5%) casos la afectación fue bilateral. La media de edad de inicio de la sintomatología fue de 41,9±20,3 años. Durante la infancia, 36 (60,0%) pacientes sufrieron movimientos migratorios, y 26 (43,3%) problemas dentarios. La edad media de inicio laboral fue de 14,6±4,5 años. Se trataron de forma ortopédica 35 (58,3%) casos frente a 25 (41,7%) tratados quirúrgicamente, 11 (18,3%) mediante osteotomía de calcáneo y 14 (23,3%) con artrodesis. Conclusiones: Al igual que en la serie de Maceira y Rochera, encontramos una mayor prevalencia de EMW entre los nacidos alrededor de la Guerra Civil española y el periodo de movimientos migratorios masivos acontecidos en la quinta década del siglo xx. El tratamiento sigue sin estar bien establecido.(AU)

Background and aim: Müller-Weiss disease (MWD) is a rare anomaly of the tarsal scaphoid. Maceira and Rochera proposed the most commonly accepted etiopathogenic theory, in which dysplastic, mechanical, and socioeconomic environmental factors would be involved. The aim is to describe the clinical and sociodemographic characteristics of patients with MWD in our setting, corroborate their association with the socioeconomic factors previously described, estimate the influence of other factors involved in the development of MWD, and describe the treatment carried out. Materials and methods: Retrospective study of 60 patients diagnosed with MWD in 2 tertiary hospitals of Valencia (Spain) between 2010 and 2021. Results: Sixty patients were included, 21 (35.0%) men and 39 (65.0%) women. In 29 (47.5%) cases, the disease was bilateral. The mean age of onset of symptomatology was 41.9±20.3 years. During childhood, 36 (60.0%) patients suffered migratory movements, and 26 (43.3%) had dental problems. The mean age of onset was 14.6±4.5 years. Thirty-five (58.3%) cases were treated orthopedically versus 25 (41.7%) treated surgically, 11 (18.3%) by calcaneal osteotomy, and 14 (23.3%) with arthrodesis. Conclusions: As in the series of Maceira and Rochera, we found a higher prevalence of MWD among those born around the Spanish Civil War and the period of massive migratory movements that occurred in the fifth decade of the 20th century. Treatment is still not well established.(AU)

Combined Pedicled Vascularized and Wedge Nonvascularized Bone Graft for Treating Scaphoid Waist Nonunion With Humpback Deformity.

Pedicled vascularized bone graft (VBG) is a useful method in treating the scaphoid fracture nonunion, especially when the avascular necrosis exists. Humpback deformity is an important issue that we have to correct it during the treatment. We describe a method by using combined wedge non-VBG to correct the nonunion deformity when treating scaphoid nonunion with pedicled VBG. The wedge bone graft was harvested just proximal to the 2,3 intercompartmental supraretinacular artery VBG and was used as an inlay at the volar site to correct the humpback deformity, whereas the VBG was set at the dorsal site for bone bridging and blood supply. We also present our results of 10 patients with scaphoid fracture nonunion and humpback deformity treated with this method. Bone healing was achieved and the lateral intrascaphoid angles could be improved in all the 10 patients. Functional outcomes, including the Visual Analog Pain Scale for pain during activity, grip strength, the shortened Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), and the modified Mayo Wrist Scores, were significantly improved.

Dysplasia epiphysealis hemimelica combined with contralateral accessory scaphoid bone: A case report and literature review.

RATIONALE: Dysplasia epiphysealis hemimelica (DEH), also known as Trevor disease, is a rare, developmental bone disorder of childhood. PATIENT CONCERNS: A 9-year-old girl was admitted due to pain in front of the medial malleolus of her right foot after a long walk or distance movement, in which the pain could be relieved after rest, while it was repeated and lasted for several months. DIAGNOSIS: Dysplasia epiphysealis hemimelica INTERVENTIONS:: The patient underwent an open resection surgery. After operation, the pain was totally relieved. Postoperative pathological diagnosis showed DEH. OUTCOMES: At the 6-month follow-up, pain and claudication symptoms fully disappeared, and range of motion of the right foot returned to normal level. CONCLUSIONS: Dysplasia epiphysealis hemimelica is an uncommon disease which can cause pain of foot in children. LESSONS: When the pediatric orthopedic surgeon treated the children suffered with foot pain should be aware of this rare disease, especially accessory scaphoid bone was found in another foot.

Arthroscopic treatment of scaphoid nonunion with humpback deformity and DISI with corticocancellous bone grafting: Technical note.

For two decades, scaphoid nonunion has been treated arthroscopically. However, compressed cancellous bone graft does not have the same mechanical properties as corticocancellous bone graft for reducing the scaphoid humpback deformity and DISI tilt. Here, we describe an arthroscopic technique to treat Alnot stage IIB scaphoid nonunion. We treated a 27-year-old male patient for scaphoid waist nonunion with humpback deformity and DISI. A 8×8×10 mm cylindrical corticocancellous bone graft was harvested from the dorsal aspect of the radius using a single-use osteochondral autograft transfer system (OATS®, Arthrex Inc., Naples, USA). It was inserted in the nonunion site through an arthroscopic volar approach. Bone union was obtained at 3 months with lasting correction of the scaphoid humpback deformity and DISI. The functional result at 6 months was excellent. There were no complications. Scaphoid nonunion with humpback deformity and DISI may be treated arthroscopically with a corticocancellous bone graft.

Scaphoid-trapezium hereditary coalition. A case report. / Coalición carpiana escafotrapezoidea hereditaria. A propósito de un caso.

Carpal coalitions are relatively frequent between bones in the same carpal row. Coalitions between bones of different rows, however, are very uncommon. We present a case of bilateral intercarpal coalition between the trapezium and scaphoid as an incidental finding, confirming its hereditary origin since a parent has the same bilateral coalition.

[The scaphoid fracture : Between pseudoarthrosis and possible anatomical variance]. / Die Skaphoidfraktur : Zwischen Pseudarthrose und möglicher anatomischer Varianz.

The diagnosis of a scaphoid fracture, especially in the differentiation of a fresh fracture, the nonunion or a possible anatomical norm variant, can be difficult. We report on two patients who presented with stress-related, radiocarpal pain in our department. In both cases, radiological abnormalities were observed in the scaphoideal area, with a scaphoideum bipartitum on both sides, as well as an approximately 25-year-old scaphoid pseudarthrosis.

Unilateral fusion of the scaphoid and the trapezium.

Fusion of the carpal bones is a rare anatomical abnormality, caused by a defect in the separation and cavitation during embryonic development. It has a prevalence of about 0.1% and most of the time, patients do not present with symptoms. Symptoms are usually caused by wear and tear of the ligaments attached to the fused carpal fragments. We present a case in which a woman aged 36 years experiences pain caused by a lunato-triquetral instability which in turn is caused by a unilateral complete fusion of the scaphoid and the trapezium. A unilateral complete fusion of the scaphoid and trapezium has not been reported before.

Escafoides tarsiano accesorio y disfunción del tibial posterior. A propósito de un caso (AU) / Accessory navicular bone and posterior tibial tendon dysfunction. A case report

Objetivo: Mostrar mediante un caso clínico que, aunque los huesos accesorios del pie no suelen ser sintomáticos, la presencia del escafoides accesorio, pueden ser responsables de un cuadro clínico doloroso y de disfunción del tibial posterior. Planteamos la cirugía para los casos que no se resuelven con medidas conservadoras. Material y método: paciente mujer de doce años con clínica dolorosa en el mediopié. Se diagnosticó de escafoides tarsiano accesorio e insuficiencia del tendón tibial posterior. Tras el fracaso del tratamiento conservador, se llevó a cabo la exéresis de dicho hueso y la reinserción del tibial posterior en la zona plantar del escafoides. Resultados: tras la cirugía se consiguió sólo la resolución del cuadro doloroso sin conseguir resolver el aplanamiento y valgo. La paciente permaneció asintomática. Conclusiones: No debe desestimarse el tratamiento quirúrgico para resolver la clínica, pero sólo debe emplearse

Background: accessory navicular bone is rarely symptomatic. However, pain and flat foot are associated in some cases. Surgery is recommended when the conservative treatment fails. Methods: we report a case of a 12 year old dancer girl with pain localized to the navicular tuberosity and medial foot, and diagnosis of accessory navicular bone associated with posterior tibial tendon dysfunction. Nonsurgical measures dind´t provide relief, so we underwent the navicular accessory excission and posterior tibial tendon advancement. Results: after surgery, the pain improved but not the appearance and functional discapacity. Our patient achieved a good clinical result. Conclusion: even surgical treatment is considered, it is indicated when conservative procedures don't relief the symptoms

Bilateral bipartite carpal scaphoid: a case report and literature review.

Congenital bipartite carpal scaphoid has been reported as an extremely rare congenital anomaly. We report a case of a 47-year-old man who was found with bilateral bipartite carpal scaphoids with no history of injury. Radiographs demonstrated symmetric findings of the distinct bipartition of the scaphoid without obvious degenerative change in both wrists. The patient complained of no other symptoms. The diagnostic differentiation of scaphoid bipartition from the pseudarthrosis of the scaphoid could be important in avoiding unnecessary surgery and inappropriate assessment in compensation cases.

Bilateral scaphotrapezium-trapezoid coalition with bipartite scaphoid: case report.

We report on a 15-year-old girl with bilateral scaphotrapezium-trapezoid coalitions and bipartite scaphoids. There was no history of trauma or any other associated pathology. Wrist pain was alleviated by arthrodesis of the pseudarthrosis of the scaphoid component of the coalitions. Coalition of the distal portions of the scaphoids may have interfered with union of 2 ossification centers of the scaphoid. It is also possible that the carpal coalitions predisposed the scaphoid to fracture and that this represents bilateral nonunion.

Ausencia congénita unilateral del escafoides carpiano y displasia del hueso grande. A propósito de un caso / Unilateral congenital absence of the carpal scaphoid associated with dysplasia of the capitate. Presentation of a case

Presentamos un caso de aplasia o ausencia congénita unilateral del escafoides carpiano asociado a displasia del hueso grande. La ausencia congénita del escafoides carpiano es una entidad rara e infrecuente, pero bien documentada. Es el séptimo caso presentado en la literatura. A diferencia de la mayoría de los casos publicados de aplasia/hipoplasia de escafoides carpiano, en nuestro caso no se ha detectado asociación de otras anomalías congénitas tipo hipoplasia o aplasia de musculatura tenar y antebrazo, malformaciones del esqueleto del pulgar, ausencia de huesos sesamoideos o alteraciones del desarrollo de los huesos del antebrazo. El estudio radiológico revela la ausencia congénita del escafoides asociado a una displasia del hueso grande e hipoplasia de la estiloides radial. Se completa el estudio con resonancia magnética nuclear (AU)

We report on a case of aplasia or unilateral congenital absence of the carpal scaphoid associated with dysplasia of the capitate. Congenital absence of the carpal scaphoid is a rare but well-documented condition. As far as we know, the present case is the seventh one reported in the medical literature. Imaging studies (X-ray and MRI) confirmed the absence of the carpal scaphoid associated with a dysplasia of the capitate and malformation of the radial styloid process. Congenital absence of the scaphoid when other congenital abnormalities (such as hypoplasia or aplasia of either forearm bones or thenar eminence, malformations of the skeletal elements of the thumb, absence of sesamoid bones or abnormal development of the forearm bones) do not exist is probably the main feature of the present case report (AU)

Unusual coalition of the carpal bones with simian crease: a case report.

We present a case of scapholunate coalition with absent fifth metacarpal on one hand, and scapholunate triquetral coalition on the other hand. The patient was asymptomatic, though he was aware of the deformity of the little and ring fingers on the right hand. No treatment was offered as the deformity was not incapacitating and the syndactyly did not interfere with hand function.

El pie plano; las recomendaciones del traumatólogo infantil al pediatra / Flat feet; recommendations from the pediatric orthopaedic surgeon to the pediatician

El pie plano es una situación clínica caracterizada por la desaparición o no formación del arco plantar. Sus formas pueden ser variadas y fundamentalmente banales, pero algunas pueden requerir un tratamiento quirúrgico. La forma más frecuente es el pie plano flexible, que es difícil de diferenciar de un pie normal, y que mejora espontáneamente con el crecimiento. Otras formas de pie plano deben diferenciarse y evaluarse adecuadamente, ya que pueden llegar a requerir tratamientos quirúrgicos. Se proponen algunas recomendaciones prácticas desde la perspectiva del traumatólogo infantil (AU)

Flat feet is the result of the disappearance or lack of formation of the arch of the feet. It has varied shapes and are mainly commonplace, but some may require surgery. The most frequent is flexible flat feet, which is difficult to differentiate from a normal foot, and which improves spontaneously with growth. Other types of flat feet should be differentiated and evaluated properly, as they might require surgical treatment. There are several practical recommendations from the perspective of pediatric orthopedists (AU)

Carpal coalition with radioscaphoid synostosis and hypoplastic thumb.

Carpal coalition is an anomaly that is usually discovered as an incidental finding on roentgenograms. The most common site is between the lunate and the triquetrum, though fusion of almost every combination of carpal bones has been reported. Carpal coalition can be isolated but has also been associated with numerous congenital malformation syndromes. In this article, we report the case of a 12-year-old boy with left-sided asymptomatic fusion of the trapezoid and trapezium, fusion of the radius and scaphoid, and hypoplasia of the thumb.
