Injury to the Main Branch of the Saphenous Nerve following Hamstring Tendon Graft Harvesting: A Report of 3 Cases.

Background: Hamstring tendon grafts are commonly utilized tendon autografts; however, the harvesting procedure can result in saphenous nerve injury due to its proximity to the semitendinosus and gracilis tendons. Injury to the main branch of the saphenous nerve is a less commonly reported and understood injury during these procedures.

Purpose: This case report aimed to identify and present cases of iatrogenic injury to the main branch of the saphenous nerve during hamstring tendon graft harvesting.

Analysis of Cephalometric Differences of the Midface and Upper Face in Males and Females: A Radiographic Study.

Gender affirmation facial surgery (GAFS) is an important component in treating gender dysphoria among transgender individuals by addressing gender incongruence of the face. There is a paucity of literature describing objective characterizations of the anatomic differences between male and female faces. In this study, cephalometric measurements were taken on routine CT imaging performed on cisgender patients between 2017 and 2020.

Critical Portions of a Foot or Ankle Surgical Procedure From Patient and Surgeon Perspectives.

Background: Over the past decade, overlapping procedures in orthopaedic surgery have come under increased public scrutiny. Central to this discussion is what should constitute a "critical portion" of any surgical procedure-a definition which may differ between patients and surgeons. This study therefore aimed to assess which components of three common foot and ankle procedures are considered "critical" from both the patient and surgeon perspectives.

Comprehensive Characterization of Operon Activation in .

Wildtype cells cannot grow on L-1,2-propanediol, as the operon within the fucose () regulon is thought to be silent in the absence of L-fucose. Little information is available concerning the transcriptional regulation of this operon. Here, we first confirm that operon expression is highly inducible by fucose and is primarily attributable to the upstream operon promoter, while the promoter within the 3'-end of is weak and uninducible.
