Metal-on-metal (MoM) hip resurfacing was introduced into clinical
practice because it was perceived to be a better alternative to
conventional total hip replacement for young and active patients.
However, an increasing number of reports of complications have arisen
focusing on design and orientation of the components, the generation
of metallic wear particles and serum levels of metallic ions. The
procedure introduced a combination of two elements: large-dimension
components and hard abrasive particles of metal wear. The objective
of our study was to investigate the theory that microseparation
of the articular surfaces draws in a high volume of bursal fluid
and its contents into the articulation, and at relocation under
load would generate high pressures of fluid ejection, resulting
in an abrasive water jet. This theoretical concept using MoM resurfacing components (head
diameter 55 mm) was modelled mathematically and confirmed experimentally
using a material-testing machine that pushed the head into the cup
at a rate of 1000 mm/min until fully engaged.Objectives
Methods
Negative pressure wound therapy (NPWT) and vessel loop assisted
closure are two common methods used to assist with the closure of
fasciotomy wounds. This retrospective review compares these two
methods using a primary outcome measurement of skin graft requirement. A retrospective search was performed to identify patients who
underwent fasciotomy at our institution. Patient demographics, location
of the fasciotomy, type of assisted closure, injury characteristics,
need for skin graft, length of stay and evidence of infection within
90 days were recorded.Introduction
Methods
Surgical marking during tendon surgery is often used for technical
and teaching purposes. This study investigates the effect of a gentian
violet ink marker pen, a common surgical marker, on the viability
of the tissue and cells of tendon.
