Carpometacarpal Joint Dislocations: Management and Long-Term Outcomes at a Specialized Hand Surgery Center in Latin America.

Carpometacarpal joint dislocations are uncommon hand injuries. These dislocations are usually misdiagnosed due to their non-specific clinical signs and tend to be difficult to identify in simple X-rays. We report our experience in the management of carpometacarpal bone dislocations at a specialized hand surgery center. Patients with carpometacarpal dislocations seen at the emergency department between 2013 and 2017 were included. All patients were treated with either closed reduction and percutaneous pinning (CRPP) or open reduction and internal fixation (ORIF). Postoperative functional assessment was performed at 6 and 18 months using the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Eleven patients were included, 8 (72%) were managed with CRPP and the rest required ORIF (28%). For the functional outcome, we found an average DASH score of 27.9 at the 6 months threshold and of 1.5 at the 18 months threshold. Carpometacarpal dislocations are uncommon and easy to misdiagnose; the hand surgeon should have a high clinical suspicion in patients who sustained high-energy trauma, and imaging studies should be thoroughly evaluated. Closed reduction and percutaneous pinning is a safe and effective treatment option, with long-term good functional results.

Les dislocations des articulations carpométacarpiennes sont des blessures peu courantes de la main. Elles sont généralement mal diagnostiquées en raison de leurs signes cliniques non spécifiques et ont tendance à être difficiles à dépister au moyen d'une simple radiographie. Les auteurs rendent compte de leur expérience dans la prise en charge des dislocations des os carpométacarpiens dans un centre spécialisé de chirurgie de la main. Les patients atteints d'une dislocation carpométacarpienne vus à l'urgence entre 2013 et 2017 étaient inclus dans l'étude. Tous les patients ont subi une réduction fermée et un embrochage percutané (RFEP) ou une réduction ouverte et une fixation interne (ROFI). L'évaluation fonctionnelle postopératoire a eu lieu au bout de six et 18 mois au moyen du score d'incapacité du bras, de l'épaule et de la main (DASH). Onze patients ont participé : huit (72 %) ont subi une RFEP et les autres ont dû subir une ROFI (28 %). Le score DASH moyen du résultat fonctionnel s'établissait à 27,9 au seuil de six mois et à 1,5 à celui de 18 mois. Puisque les dislocations carpométacarpiennes sont rares et faciles à mal diagnostiquer, le chirurgien de la main devrait en présumer la possibilité chez les patients victimes d'un traumatisme de forte énergie, et les études d'imagerie devraient faire l'objet d'une évaluation approfondie. La RFEP est une possibilité de traitement sécuritaire et efficace qui donne de bons résultats fonctionnels à long terme.

Hernia interna estrangulada por plastrón en el tercio distal del apéndice cecal. Reporte de un caso / Internal Hernia Strangulated by Plastron in the Distal Third of the Cecal Appendix. Case Report

Resumen Las hernias internas son causa infrecuente de obstrucción intestinal con una incidencia del 0.2-0.9%, por lo que su diagnóstico temprano representa un reto. El órgano más frecuentemente herniado es el intestino delgado, lo que confiere un gran espectro de síntomas, desde dolor abdominal ligero hasta datos de abdomen agudo1,2. Se presenta el caso de una paciente de 8 años de edad con sintomatología digestiva inespecífica; se realizó diagnóstico transoperatorio en el que se encontró hernia interna estrangulada por plastrón en el tercio distal del apéndice. Se realizó apendicectomía y a los cuatro días se dio de alta sin complicaciones.

Abstract Internal hernias are an infrequent cause of intestinal obstruction with an incidence of 0.2-0.9%, therefore their early diagnosis represents a challenge. The most frequently herniated organ is the small bowel, which results in a wide spectrum of symptoms, varying from mild abdominal pain to acute abdomen1,2. We present the case of an eight-year old patient with nonspecific digestive symptoms, a transoperative diagnosis was made in which an internal hernia was found strangulated by plastron in the distal third of the appendix. Appendectomy was performed and four days later the patient was discharged without complications.

Malformación vascular capilar y venosa en la mano. Reporte de caso de una extraña patología quirúrgica / Vascular capillary and venous malformation in the hand. Case report of a strange surgical pathology

Resumen Introducción: Las anomalías vasculares representan un amplio panorama de distintas lesiones donde los tumores son los más frecuentes. Las malformaciones vasculares suelen presentarse en etapas tardías de la vida secundarias al lento crecimiento y a los síntomas que padecen los pacientes. Debe de darse un manejo multidisciplinario donde el diagnóstico es la piedra angular. Los casos de malformaciones venosas o linfáticas suelen tratarse mediante la resección de la malformación en su totalidad. Presentación del caso clínico: Varón de 35 años de edad quién presenta aumento de volumen y dolor de 3 meses de evolución en la mano derecha. A la exploración física se observa una masa en la región tenar de dicha mano, con bordes bien definidos de aproximadamente 3 × 3 cm, no móvil, adherida a planos profundos, dolorosa a palpación, con hiperestesias en trayecto del nervio mediano. Se realizaron ultrasonido Doppler y resonancia magnética, los cuales sugirieron una lesión vascular. Se realizó exploración quirúrgica y se observó una lesión vascular adherida a las estructuras nerviosa y tendinosa, las cuales se liberaron y se extrajo la tumoración. Se envió la pieza quirúrgica a patología, que reportó hemangioma capilar y venoso. Conclusiones: Las malformaciones vasculares mixtas (venoso y capilar) en la mano son una entidad poco frecuente que requiere de un manejo quirúrgico preciso. Estas lesiones generan síntomas asociados al aumento de volumen, entre los que destacan: dolor, disminución del rango de movimientos. El tratamiento quirúrgico se asocia a una mejoría de los síntomas.

Abstract Introduction: Vascular anomalies in the hand represent a rare disease that needs an accurate diagnosis and prompt surgical treatment. One of the uncommon anomalies is the mixed vascular one. The diagnosis of these malformations is clinical but radiological studies such as magnetic resonance and Doppler ultrasound are mandatory. Once the diagnosis is made, surgery is the next and final step. Recurrence is rare when the entire tumor is resected. Clinical Case Study: A 35-year-old male presented with an increase in volume and pain of three months of evolution in the right hand. On physical examination, a mass in the righthand thenar region was observed, with well-defined edges of approximately 3 x 3 cm, not mobile, adhered to deep planes, painful to palpation, with hyperesthesias in the median nerve pathway. A magnetic resonance and a Doppler ultrasound were applied showing a well-circumscribed tumor. The patient underwent surgery and the whole vascular malformation was removed with no damage of neighbor structures. Pathology reported a venous and capillary hemangioma. Conclusions: Mixed vascular malformations in the hand are uncommon pathologies that require a correct diagnosis and a prompt surgical resolution. The most frequent symptoms associated with these tumors are: tenderness, pain and limitation in the movement of the hand. Surgical treatment is always recommended.

Surgical-Based Classification for Microtia.

The known classifications for microtia have been cumbersome and difficult to apply in daily consultation. The lack of a progressive surgical behavior according to each degree of affection also contributes to confusion and in a lower success rate in clinical application. The authors propose a progressive surgical classification that takes into consideration the principal anatomical defect and the corresponding correction with modern techniques, having eliminated from previous classifications, those elements that are now considered deformations of the ear, capable of conservative treatment in early stages of life.

Mozart Ear Deformity: a Rare Diagnosis in the Ear Reconstruction Clinic.

Mozart ear is a rare auricular deformity; clinically the auricle is characterized by the bulging appearance of the anterosuperior portion of the auricle due to fusion of the crura of the antihelix, an inversion in the normal form of the cavum conchae resulting in its convexity and a slit-like narrowing of the orifice of the external auditory meatus.A retrospective review of clinical and photographic records of patients attended at the ear reconstruction clinic of our hospital between June of 2010 and May 2016 was performed; out of 576 consecutive patients only 3 fulfilled the inclusion criteria, with a prevalence of 0.5%. The authors present these patients.Surgical interventions mainly focus on the correction of the convex concha; however, the procedure should be tailored to the severity of the deformity and the wishes of the patient.
