“…With so few cases, definitive conclusions about the mechanism of injury and treatment outcomes are not available. Direct force to the triquetrum or wrist extension and ulnar deviation have been the proposed mechanisms of injury in a few of the reported cases [31,32]. Both volar and dorsal displacements have been seen, with volar displacement being associated with transient median nerve compression.…”

Carpal dislocations are rare but devastating injuries. They most often occur from high-energy trauma such a motor vehicle accidents, falls from a height, or industrial-related accidents. Encompassing a spectrum of pathology, these injuries include perilunate dislocations, transcarpal fracture-dislocations, radiocarpal dislocations, axial or longitudinal dislocations, and the rare isolated carpal bone dislocations. A thorough understanding of the carpal anatomy, injury patterns, and treatment options is critical for proper management of these serious injuries. In this article, the authors address the five main categories of carpal dislocations, the associated anatomy, and their diagnosis, treatment, and prognosis.

“…Hemos encontrado en la literatura solo 6 casos de luxaciones aisladas del piramidal [6][7][8][9][10][11] , con desplazamiento del hueso hacia dorsal o volar, con una incidencia similar de ambos tipos. Aunque esta lesión se referencia como una luxación aislada del piramidal, suele haber un desplazamiento asociado del pisiforme en mayor o menor grado, como ocurrió en nuestro caso, perdiéndose la congruencia de las superficies articulares de ambos huesos a nivel de la articulación pirámido-pisiforme, lo que cuestiona la validez de denominar estas lesiones como luxación aislada del piramidal.…”

Recibido el 18 de junio de 2016; aceptado el 26 de agosto de 2016 PALABRAS CLAVE Piramidal; Luxación volar; Lesión carpoResumen Aunque las luxaciones carpianas son lesiones relativamente frecuentes, la luxación aislada del piramidal es excepcional. Presentamos un caso aislado de luxación volar del hueso piramidal, revisando los casos similares publicados en la literatura y analizando los aspectos más importantes en relación con su diagnóstico y tratamiento.Varón de 38 años de edad, con caída sobre su mano derecha en hiperextensión. Inicialmente el diagnóstico pasó desapercibido. Al mes se realizó reducción abierta y estabilización con agujas de Kirchner.A los 4 años de la cirugía el paciente se encuentra asintomático y con la misma fuerza de agarre que la mano contralateral. Las radiografías postoperatorias muestran una buena reducción del carpo sin signos de inestabilidad.La falta de un diagnóstico inicial y en consecuencia un retraso en el tratamiento hacen más difícil el manejo de las lesiones, pero es una reducción inadecuada del carpo el factor pronóstico más negativo. © 2016 SECMA.

KEYWORDS Triquetrum; Volar dislocation; Carpal injury Isolated dislocation of the triquetrumAbstract Although carpal dislocations are a relatively common injury, isolated dislocation of the triquetrum is exceptional. The report of a new case is presented of isolated volar dislocation of the triquetrum, as well as an analysis of similar cases published in the literature. The main factors related to their diagnosis and treatment are also reviewed.A 38-year-old man fell and landed on his right hand in hyper-extension. Diagnosis was initially unnoticed. An open reduction and Kirchner wires stabilisation was performed one month later. * Autor para correspondencia. Correo electrónico: fegosu@yahoo.es (F. Gómez-Suárez).http://dx

Volar Dislocation of the Triquetrum - Case Report and Review of Literature

et al. 2016

In contrast to triquetral fractures, dislocations of the triquetrum are very uncommon because of the very strong ligamentous support. They occasionally occur in association with complex wrist injuries, isolated dislocations however are extremely rare. We report a case of a male athlete who sustained an isolated volar dislocation of the triquetrum. The injury was treated by open reduction, fixation with Kirschnerwires and direct repair of torn ligaments. Kirschner-wires were removed after 6 weeks and physiotherapy was started. At 3 years follow-up he reported to be free of pain and showed only slightly restricted grip strength and range of motion when compared to his uninjured hand. A review of the literature indicates that final outcomes are usually satisfactory if prompt diagnosis and treatment occurs. However persistent pain and impaired hand function may result because of delayed diagnosis or insufficient repair of associated ligament injuries.
