"For the bone contacting surface, it's important that surface should promote bone ingrowth
or ongrowth for better attachment," explained Parimal Bapat, Ph.D., a research engineer at Orchid Orthopedic Solutions, a Lansing, Mich.-based provider of orthopedic medical device outsourcing, offering contract design and manufacturing services.
With regard to stem stability, 108 hips were classified as fixation by bone ingrowth
, and two as stable fibrous ingrowth
; none were classified as unstable.
The mid-portion of this stent is covered with a membrane to prevent tumor ingrowth
. Both the proximal end (2 cm) and distal end (0.5 ~ 1 cm) of the stent are uncovered.
There are two main concepts in acetabular reconstruction: one is to achieve rigid containment and recover bone stock using metal mesh or reinforcement devices with bone grafting to stabilize the cemented cup and the other is to achieve bone ingrowth
using a cementless cup with or without bone grafting or augmentation devices.
They found that AM implants displayed significantly more bony ingrowth
into the device's core versus superficial ingrowth
with the TPS coated implant.
Stent obstruction due to tumor ingrowth
occurred in two patients, 13 and 20 weeks after stent placement.
In the present study, all 215 cups had stable fixation by bone ingrowth
at an average follow-up of 4 years, and a minimum cup-CE angle of-9.2[degrees] (BCI: 48.8%) was acceptable for stable bony fixation.
This can provoke bone tissue ingrowth
, consequently leading to the development of a stable interface between the scaffold and host tissue .
It can be due to either tumor overgrowth/ ingrowth
into the stentmesh or impaction of food bolus.
TLIF (Transforaminal Lumbar Interbody Fusion) cage is a miniature device made out of Tritanium or porous Titanium by Stryker company that allows for bone ingrowth
or bone growth through the cage which is far superior than other materials allowing for it to be best incorporated by the vertebral bodies or bones of the spine column.
Prolene meshes cause parietal ingrowth
, which repairs and strengthens the hernia repair.
Biosynthetic meshes provide a temporary scaffold for deposition of proteins and cells necessary for tissue ingrowth
, neovascularization and host integration (Kim et al., 2014).
