Middle meningeal artery hemorrhage: an incorrect name.

Extradural hemorrhage is most commonly assumed to result from a middle meningeal artery rupture. This article challenges that assumption. The meningeal vasculature of 29 cadaveric specimens was examined macroscopically and microscopically at the level of the greater wing of the sphenoid bone and foramen spinosum. It was observed that the middle meningeal artery is accompanied by a pair of dural sinuses throughout the majority of its course, thus making exclusively arterial rupture an anatomical improbability. Furthermore, as these dural sinuses pass caudally through the foramen spinosum with the middle meningeal artery, they were seen to diverge to form a plexiform arrangement around the artery. This has not been reported before.

Population-based analysis of the risk of adhesion-related readmissions after abdominal surgery in children.

PURPOSE: The aim of this study was to quantify the risk of adhesion-related readmissions after abdominal surgery in children. METHODS: This was a population-based study. One thousand five hundred eighty-one children younger than 16 years underwent laparotomy in 1996. Patients were identified from the Scottish Morbidity Records database and followed up for 4 years. RESULTS: In children younger than 5 years, 4.2% had a readmission "directly" owing to adhesions. In children younger than 16 years, 1.1% had a readmission directly owing to adhesions. The highest risk of readmission followed surgery on the small intestine (9.3%), followed by abdominal wall surgery (5.8%), duodenal surgery (2.6%), colonic surgery (2.1%), and appendicectomy (0.3%). 55% of all readmissions occurred in the first year. CONCLUSION: There was no difference in readmission rates between younger and older children when comparing the organ on which surgery was initially performed. The highest readmission rate followed small intestinal surgery and the lowest followed appendicectomy. The risk of readmission was highest in the first year.

The Spencer Wells forceps.

This is the first of a six-part biographical series tracing the lives of the people behind some of today's most commonly used surgical instruments. Surely the most recognisable 'name behind the instrument' must be that of Sir Thomas Spencer Wells (1818-1897), whose ratchet haemostatic forceps represented a simple but important advance in surgical instrument technology.

The Sims' speculum.

An instrument that is taken for granted in gynaecological clinics, operating theatres and GP surgeries all over the world is the humble Sims' speculum. How would we manage without it? In the fourth article of this biographical series, Professor Ellis looks at the work of James Marion Sims.

Charnley's hip prosthesis.

When he sat the FRCS examination in 1951 Harold Ellis was advised that, if asked by the examiner, 'What is the best treatment for osteoarthritis of the hip?' to reply, 'Provide the patient with a walking stick and prescribe aspirin.' The results of surgery for this condition at that time were pretty discouraging. Here, Professor Ellis outlines the development of this surgical technique.
