Here, we present a standardized series of protocols to observe the superior ocular sulcus, a recently-identified, evolutionarily-conserved structure in the vertebrate eye. Using zebrafish larvae, we demonstrate techniques necessary to identify factors that contribute to the formation and closure of the superior ocular sulcus.

Intra-articular Shoulder Injection for Reduction Following Shoulder Dislocation

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA The anterior shoulder dislocation is one of the most common joint dislocations seen in emergency settings. In anterior shoulder dislocation, the humeral head is displaced out of the glenohumeral joint in front of the scapular glenoid, resulting in a loss of the articulation between the arm and the rest of the shoulder. This can be caused by a fall onto an abducted, extended, and externally...
FAQs
Rouviere's Sulcus gives the surgeon a spatial reference for interpreting the inferior visceral surface of the liver during hepatobiliary surgery. Its horizontal course to the right of the hepatic hilum and posterior relationship to the porta hepatis help organize the operative field. This orientation supports identification of a safer dissection plane before work proceeds around the extrahepatic bile ducts.
Because the sulcus lies posterior to the porta hepatis, it helps distinguish the posterior reference region from the plane containing the extrahepatic bile ducts. That relationship allows the surgeon to use the landmark as an anatomical boundary during dissection. Maintaining awareness of this spatial arrangement can reduce the likelihood of extending dissection into structures associated with the common bile duct.
The landmark reflects the location of the right posterior portal pedicle, giving it significance beyond surface appearance. It also helps define the plane of the extrahepatic bile ducts. Recognizing these associations connects visible liver anatomy with deeper portal structures, allowing operative decisions to follow consistent anatomical relationships rather than relying only on the immediate dissection view.
Dissection should remain above and anterior to Rouviere's Sulcus when the landmark is used for orientation. This position keeps the operative plane away from the deeper posterior reference represented by the sulcus and its associated portal anatomy. In laparoscopic cholecystectomy, that spatial discipline is intended to lower the risk of injuring the common bile duct.
During laparoscopic cholecystectomy, the surgeon identifies the sulcus and uses its course to orient the working field before dissecting near the biliary structures. The landmark helps maintain dissection above and anterior to the reference groove. Applying this relationship provides a reproducible anatomical guide and supports safer decisions as the extrahepatic bile duct region is approached.
Its principal practical value is prevention of common bile duct injury through better anatomical orientation. By relating the sulcus to the right posterior portal pedicle, porta hepatis, and extrahepatic bile duct plane, surgeons can make dissection choices with a clearer spatial framework. This contributes to safer operative anatomy and more consistent decision-making in hepatobiliary procedures.
