Describing the sternalis muscle: a new variant and an amended classification.

Purpose: With emphasis on the clinical setting, knowledge of anatomical variation decreases misdiagnoses and surgical complications. We report a previously undocumented variant of sternalis muscle and recommend an augmented classification scheme.

Methods: Dissection of the anterior thoracic wall on an 83-year-old female cadaver revealed bilateral sternalis muscles.

A previously unclassified variant of sternalis muscle.

Purpose: We propose an addition to the Snosek et al. classification to include a subtype variant of sternalis muscle: mixed type and triple subtype.

Methods: Dissection of the anterior thorax of a 96-year-old female cadaver revealed bilateral sternalis muscles with an undocumented variant of the right sternalis muscle.

Randomized, prospective comparison of open and closed peritoneal lavage for abdominal trauma.

Study Objective: The study was designed to determine if open peritoneal lavage is superior to closed peritoneal lavage.

Design And Participants: Patients who were admitted to a trauma center and needed peritoneal lavage were assigned to alternate trauma teams. Team 1 performed only open lavages one month and then switched to closed lavages; team 2 did only closed lavages and then switched to open lavages.
