Sports hernia – tear of the rectus abdominus / adductor longus
Hi all. I have never seen anything on this topic anywhere in the forums and I wanted to share my story in hopes that it may help someone else. My story is very long, but for purposes here, I will keep my initial post brief and go into further detail if asked.

June 1, 2018 – BARCELONA, Spain – Total surface replacement may still be a viable hip arthroplasty option in young, active patients based on how well it fared in a study when it was revised to total hip replacement vs. primary THR that was revised to THR, according to a presenter at the EFORT Annual Congress…

The issue of cup slippage in the immediate postop period is a controversial one.
While bone ingrowth takes around 6 wks. – the hydroxy apatite to bone chemical reaction can occur much more quickly.
If we surgeons feel that the cup is not perfectly tight ( press fit) during the surgery then we restrict activities for a 6 -8 wk period .This is done in the hope that no precipitating event would occur that would … Read the rest

Lancet article, “Failure rates of metal-on-metal hip
resurfacings: analysis of data from the National Joint
Registry for England and Wales”, by Professor AW Blom,
published on October 2, 2012.
First of all, this is an observational scientific study with
valid research design and questions; however, the
conclusions point out the limitations of registry studies

Knowing the cause of resurfacing failure can ensure
successful conversion to THR by Edwin Su, MD
The shell can be retained in cases involving femoral
neck fracture, femoral loosening or impingement.
Causes of failure
“The cause of failure must be carefully assessed prior to the
conversion surgery in order to ensure an optimal THR outcome,” Su said.
He noted that femoral neck fracture is the primary cause of short-term
failure in resurfacing procedures.
Dr. Bose – I have bone cysts, can I have a hip resurfacing?
The presence of a cysts by itself is not a contraindication for resurfacing. It does not preclude resurfacing automatically. One must keep in mind that cyst formation is a natural occurrence in osteoarthritis and is very common though the extent, quantity & location may vary.
Cysts are of course much more common and invariably present in AVN. The assessment of certain technical … Read the rest
By Dr. Rubinstein

Chicago, IL 60657
Cysts are very common in arthritic hips and can usually be
seen on x-rays. Most of the time they are not a problem with
resurfacing because they are small and in the part of the bone removed in
milling the femoral head for a resurf. Most larger ones can be filled
with a cement of bone chips and still do a good … Read the rest
As the incidence of metal-on-metal hip resurfacing has increased in recent
years, especially in younger patients, research published in the Journal
of Bone and Joint Surgery – British Volume (JBJS-Br) discusses
occurrences of “pseudotumours” as a result.
The researchers estimate that approximately 1% of patients who have
metal-on-metal hip resurfacings develop pseudotumours within five years of
treatment. A pseudotumour is ‘a soft-tissue mass associated with the
implant…neither malignant nor infective in

THR= total hip replacement
HRA= hip resurfacing arthroplasty
If an HRA has failed, I try to solve the problem by revising
only the acetabular component whenever possible because HRA are functionally
better than THR. If only the acetabular component is revised, the patient still
has a HRA. If the femoral component is revised, the patient now has a THA.
Currently revising only the acetabular component with a
metal/metal (M/M) articulation is only … Read the rest
Acoustic Phenomena in Hip Resurfacing 2009
Koen De Smet, MD; Alessandro Calistri, MD
AMC Ghent, Krijgslaan 181, 9000 Ghent, Belgium
Background: While providing superior hardness and improved wear
characteristics, hard bearings such as metal-on-metal, or ceramic-on-ceramics
bearings have different lubrication properties than hard on soft (metal- or
ceramic-on-poly) bearing couples. A failure in this lubrication mechanism in
metal-on-metal resurfacing prostheses can lead to squeaking… Read the rest

During my several years of learning and reading about hip resurfacing, I have heard of two people having dislocations. There may be more, but I only know if people post their dislocation on the various discussion boards I belong to.
One young man was doing an exercise bringing his knee to his chest. His leg was tight and he jerk his knee toward his chest and caused a dislocation of his hip resurfacing.
