“…The most striking feature in H. sapiens was the relatively large insertion site of the RSC + LRL ligaments (Figure ). These ligaments play an important role in stabilizing the radiocarpal joint in modern humans (Apergis, ; Cardoso & Szabo, ), since they limit the extension and ulnar deviation of the scaphoid and lunate during the extension and ulnar deviation of the wrist (Bateni et al, ; Nordin & Frankel, ; Ringler & Murthy, ; Short et al, ; Short et al, ). This functional importance of the two ligaments in humans reflects their histology, since they are composed of densely packed collagen fibers with little innervation, making them especially adapted to resist the axial loads transmitted through the radial region of the wrist (Hagert, ).…”

“…In addition, the RSC and LRL ligaments are an important stabilizing element of the radial region of the wrist (Cardoso & Szabo, ). The RSC ligament stabilizes the scaphoid, while the LRL and SRL ligaments stabilize the lunate (Apergis, ; Bateni, Bartolotta, Richardson, Mulcahy, & Allan, ; Cardoso & Szabo, ; Nordin & Frankel, ; Ringler & Murthy, ; Short, Werner, Green, & Masaoka, ; Short, Werner, Green, Sutton, & Brutus, ). The stabilizing function of the ligaments RSC, LRL, and SRL is of great importance during extension and ulnar deviation of the wrist because they limit the movements of extension and ulnar deviation affecting the scaphoid and the lunate in these cases (Apergis, ; Short et al, ; Short et al, ).…”

Objectives: To identify anatomic differences in the insertion sites of the palmar radiocarpal ligaments in different species of hominoid primates that may be related to their different types of locomotion. Materials and methods:We have used three-dimensional geometric morphometrics (3D GM) to analyze the distal radius ligament insertion sites in 31 Homo sapiens, 25 Pan troglodytes, 31 Gorilla gorilla, and 15 Pongo pygmaeus. We have also dissected the radioscaphocapitate (RSC), long radiolunate (LRL) and short radiolunate (SRL) ligaments in six H. sapiens and five P. troglodytes to obtain quantitative values that were then compared with the results of the 3D GM analysis.Results: H. sapiens had a relatively larger insertion site of the RSC + LRL ligament than the other hominoid primates. P. pygmaeus and P. troglodytes had a relatively large SRL ligament insertion site with a palmar orientation. In G. gorilla, the two ligament insertion sites were relatively smaller and the SRL insertion site had an ulnopalmar orientation.Discussion: The morphological differences observed can be related to the types of locomotion used by the different species and to quantitative data obtained from the dissection of ligaments in H. sapiens and P. troglodytes. 3D GM analysis of ligament insertion sites can help in interpreting the types of locomotion used by extinct hominoid primates through the analysis of preserved fossilized fragments of the distal radius.

“…The scaphoid attachment of the dorsal SL band is weaker and more likely to avulse than the stronger lunate attachment. 19,22,25,26 A partial SL ligament tear involves the palmar (weaker) or dorsal band, whereas a complete SL tear is an injury of all three segments. Moser nicely depicts on CTA the partial-thickness and full-thickness tears of the SL bands, also known as noncommunicating or communicating defects, respectively.…”

Carpal stability depends on the integrity of both intra-articular and intracapsular carpal ligaments. In this review, the role of the radial-sided and ulnar-sided extrinsic and intrinsic ligaments is described, as well as their advanced imaging using magnetic resonance arthrography (MRA) and contrast-enhanced magnetic resonance imaging (MRI) with three-dimensional (3D) scapholunate complex sequences and thin slices. In the last decade, the new concept of a so-called “scapholunate complex” has emerged among hand surgeons, just as the triangular ligament became known as the triangular fibrocartilage complex (TFCC).The scapholunate ligament complex comprises the intrinsic scapholunate (SL), the extrinsic palmar radiocarpal: radioscaphocapitate (RSC), long radiolunate (LRL), short radiolunate (SRL) ligaments, the extrinsic dorsal radiocarpal (DRC) ligament, the dorsal intercarpal (DIC) ligament, as well as the dorsal capsular scapholunate septum (DCSS), a more recently described anatomical structure, and the intrinsic palmar midcarpal scaphotrapeziotrapezoid (STT) ligament complex. The scapholunate (SL) ligament complex is one of the most involved in wrist injuries. Its stability depends on primary (SL ligament) and secondary (RSC, DRC, DIC, STT ligaments) stabilizers.The gold standard for carpal ligament assessment is still diagnostic arthroscopy for many hand surgeons. To avoid surgery as a diagnostic procedure, advanced MRI is needed to detect associated lesions (sprains, midsubstance tears, avulsions and chronic fibrous infiltrations) of the extrinsic, midcarpal and intrinsic wrist ligaments, which are demonstrated in this article using 3D and two-dimensional sequences with thin slices (0.4 and 2 mm thick, respectively).

“…Con los estudios obtenidos con RMN de 3 teslas se obtiene una especificidad de hasta el 100% comparado con la artroscopia de muñeca y una sensibilidad del 22 al 82%. Si se incluye la artroRMN en los estudios, esta sensibilidad aumenta del 50 al 100%, siendo mayor en las roturas completas que en las parciales 13 . Por otra parte, la obtención de imágenes en un plano oblicuo axial (perpendicular al intervalo EL o LP) en vez de un plano axial (perpendicular al radio) aumenta la seguridad en la detección de lesiones de los ligamentos interóseos 14 .…”

Artroscopia de muñeca; Ligamento lunopiramidal; Volar Intercalated Segmentary Instability (VISI); Inestabilidad carpianaResumen Históricamente, la inestabilidad en el lado radial de la muñeca ha recibido mucha más atención que la inestabilidad en el lado ulnar, a pesar de ser una patología relativamente frecuente. Como consecuencia de ello, suele darse un retraso en el diagnóstico correcto y el tratamiento apropiado. Las lesiones del ligamento lunopiramidal pueden ser parciales o completas, y estas últimas pueden estar asociadas a lesión de los estabilizadores secundarios. Cuando se lesionan estos estabilizadores es cuando se produce una inestabilidad estática del carpo conocida como Volar Intercalated Segmentary Instability (VISI). Entre los test clínicos más utilizados para detectar una inestabilidad del ligamento lunopiramidal están el Ballottement test, descrito por Reagan, y el Shear test, descrito por Kleinman, aunque ambos poseen una sensibilidad y una especificidad bajas. Para el diagnóstico de estas lesiones se emplean técnicas como la radiografía simple (que suele ser normal si no hay una inestabilidad estática del carpo), la artrografía y la RMN, entre otras, aunque el gold standard lo constituye la artroscopia de muñeca. No existe un consenso en cuanto al tipo de tratamiento óptimo, ya que la mayoría de los estudios publicados son retrospectivos de nivel iv sin medidas objetivas estandarizadas mediante instrumentos validados. Además, en su mayoría describen los resultados del tratamiento tardío, ya que no se suelen diagnosticar en la fase aguda. Dentro de los tratamientos descritos se encuentran el tratamiento artroscópico (desbridamiento/termocoagulación asociados o no a estabilización con agujas de Kirscher), la reparación abierta, la reconstrucción del ligamento y la artrodesis del ligamento lunopiramidal.Abstract Radial-sided wrist instability has historically received greater attention than ulnarsided instability despite being a relatively frequent pathology. As a result, there is often a delay in correct diagnosis and appropriate treatment. Lunotriquetral ligament injuries can be * Autor para correspondencia.
