Morphological Spectra of Adult Human Stellate Ganglia: Implications for Thoracic Sympathetic Denervation.

Cardiac sympathetic denervation (CSD) to treat ventricular arrhythmias (VAs) requires transection at the middle or lower third of stellate (cervicothoracic) ganglia (SG). However, the morphological appearance of the adult SG and distribution of neuronal somata within it are not well described. To determine the morphology of left and right SG (LSG and RSG) and the distribution of somata within.

Clinical implications of novel variants of the fibularis (peroneus) quartus muscle inserting onto the cuboid bone: peroneocuboideus and peroneocalcaneocuboideus.

Two variants of the fibularis (peroneus) quartus muscle were identified and photographed in the legs of a 70-year-old white male cadaver. A rare peroneocuboideus (fibulocuboideus) muscle (as described by Chudzinski) and a novel peroneocalcaneocuboideus (fibulocalcaneocuboideus) muscle was found in the right and left leg, respectively. The latter muscle has not been previously reported and was termed "peroneocalcaneocuboideus" on the basis of its origin and insertions.

Locating the sural nerve during calcaneal (Achilles) tendon repair with confidence: a cadaveric study with clinical applications.

The sural nerve is at risk of iatrogenic injury even during minimally invasive operative procedures to repair the calcaneal (Achilles) tendon. Through 107 cadaveric leg dissections, the data derived from the present study was used to develop a regression equation that will enable surgeons to estimate the intersection point at which the sural nerve crosses the lateral border of the Achilles tendon, an important surgical landmark. In most cases, the sural nerve crossed the lateral border of the Achilles tendon 8 to 10 cm proximal to the superior border of the calcaneal tuberosity.

The fibulocalcaneus (peroneocalcaneus) internus muscle of MacAlister: Clinical and surgical implications.

A fibulocalcaneus (peroneocalcaneus) internus (PCI) muscle (of MacAlister) was identified and photographed in the left leg of a 78-year-old Caucasian female cadaver. This case study provides the first gross anatomical photo of this anomalous leg muscle and represents the first gross anatomical dissection of this muscle since 1914. The PCI muscle arose from the distal third of the fibula, posterior intermuscular septum of the leg, and flexor hallucis longus muscle.
