Distal Radioulnar Joint (DRUJ) instability is a pathology without a clear reconstructive procedure. Throughout history, numerous techniques have been described whose objectives have been to increase stability as well as relieve pain. The main stabilizing element is the Triangular Fibrocartilage Complex (TFCC) and, there are also secondary stabilizers among where the Distal Oblique Bundle (DOB) is consistently located. We performed a biomechanical study with three cadaveric arms to verify the influence of DOB on joint stability and performing a new reconstruction technique with hemi tendon of carpi radialis longus extensor to get distal radio cubital stability for fiber cartilage repair. There are positive results in the volar and dorsal displacement of the ulna on the radius with the reconstruction technique presented to restore joint stability. The proposed technique is a valid and biomechanically effective option to restore joint stability as a complement to the repair of the TFCC or as a unique technique if the TFCC is irreparable. This technique became important when you cannot repair TFCC in athletes, the recommended alternative can be done and distal oblique soft plasty.
Hand and finger soft tissue defects have always represented a surgical challenge at any accident and emergency department. Techniques may vary from just direct closure of the wound to free tissue transfer. Knowledge of the main locoregional hand flaps is paramount to solve most of the soft tissue defects at this level. Flaps vary depending on their blood supply and design. Their vascularity might be at random, they can be pedicled with anterograde or reversed flow or they can rely on simple or complex free tissue transfer whose blood flow depends on vascular anastomosis. This article reviews all the main soft tissue local or locoregional reconstructive techniques for hands and fingers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
