SLIDE 3
My Position
S
ympt omat ic glut eal t ears should be repaired
By themselves if the hip is not arthritic In conj unction with THR if the hip is arthritic
No evidence t hat sympt omat ic t ears will lead t o hip OA A THR t reat s pain from cart ilage loss not from a glut eal
t ear Disclosure: a minimal evidence based t alk
SLIDE 4 What we don’ t know
How sensitive are MRI at finding abductor tears?
Beware of scanners <1.5 Tesla
How reliably do MRI abductor abnormalities predict symptomatic
tears? I have explored 1 case with a complete “ tear” and found normal
tendons
Can a small or partial tear be improved by surgery?
I don’ t operate on these but suggest consultation with an arthroscopic surgeon
Does Bursectomy help patients?
I have never done this and am highly skeptical
SLIDE 5 Incidence of isolated abductor tears?
2/ 3482 (0.06% ) patients presenting with surgical hip pain
Incidence of finding a tear with THR?
1.6% Cates 2010 22% Bunker 1997 20% Howell 2001 2% Gross 2017 I rarely operate on older women
Incidence of symptomatic tear after lateral approach?
4.9% lateral pain Iorio 2006
SLIDE 6 How often are abductor tears missed at S x? I diagnosed my first one 4/ 2009 (8 years) I now see a tear in 1-2%
(2.4% in women & 0.6% in men)
80%
Mean age HRA =52 years, tear=63 years Most tears are in older women

Approach
Lat eral:
always see t hem and repair t hem but you creat e more wit h t he approach
Ant erior:
Difficult t o see t hem
Post erior:
Can find t hem if you always make a point t o look I missed t hem all before 2009
SLIDE 10 How to find a tear?
Awareness of the problem Maybe a preop MRI Irregularity of the lateral trochanter on preop XR A few are obvious if you are not going too fast S
uspicious findings: A thick bursa
resect it and look carefully
A rough gritty feel to the trochanter
If you are suspicious carefully detach the anterior ¼ of the G.
medius and look at the minimus tendon.
The G minimus is usually the problem
SLIDE 11
Dissatisfaction with THR
Anakwe JOA 2011 7% Mancuso JOA 1997 11% How many of t hese are due t o unrecognized unt reat ed abduct or t ears?
SLIDE 12 Repairing Tears during THR
Most with 2 #2 fiberwire Krackow stiches in minimus into a
bone trough and #2 Quill absorbable medius repair
S
maller partial tears with suture anchors
Extra slow program

Cane as needed thereafter Formal PT at 6 months.
More residual pain and limp for 1 year Most have a no/ slight limp and 5-/ 5 strength at I year.

S ummary
Most pat ient s are improved by repair Large t ears probably do bet t er open S
maller t ears probably do bet t er art hroscopically
Most occur in conj unct ion wit h an art hrit ic hip Many are missed during THR possibly leading t o residual
pain and weakness
Most occur in older women
SLIDE 21
S ummary
Warn pat ient s wit h a repair t hat t hey will have a longer
recovery
Limit WB for several mont hs MARS
MRI may discover t hem in a painful THR
Unclear if a failed abduct or form a lat eral approach can
be improved wit h surgery
SLIDE 22
S ummary
Have a High index of suspicion:
Older women Incidental preop MRI Irregular lateral trochanter on XR Thick trochanteric bursa Gritty texture on lateral trochanter
If you miss these and don’ t repair them you will have more dissatisfied limping THR patients
SLIDE 23 My Opinion
Isolat ed t ears are rare…order a hip MRI for lat eral pain
,limp, and abduct or weakness
Don’ t j ust repeat edly inj ect bursit is Y
- u won’ t really help someone wit h referred back
pain
Y
- u may cause t endon degenerat ion
Y
- u’ ll miss someone who can be fixed
Therapy does not heal complet e t ears Repair complet e t ears…but set expect at ions correct ly don’ t replace t he hip unless it is bad.
