SUMMARY
The greater trochanter pain syndrome refers to pain on the lateral aspect of the hip joint. This is frequently attributedto trochanteric bursitis and distension of the subgluteal bursae. Associated tears of the tendons of gluteus medius andminimus have been described and may result from repetitive frictional trauma to these tendons and their associatedbursae secondary to impingement beneath the tensor fascia lata. Occasionally tendinous damage may result fromacute local direct trauma or a hyperadductive strain injury. We describe MRI in two patients with chronic lateralhip pain.
Key words:
greater trochanter pain syndrome; magnetic resonance imaging.
INTRODUCTION
The greater trochanter pain syndrome refers to pain on the
lateral aspect of the hip joint. This is frequently attributed to
trochanteric bursitis and distension of the subgluteal bursae.
Associated tears of the tendons of gluteus medius and minimus
have been described and may result from repetitive frictional
trauma to these tendons and their associated bursae second-
ary to impingement beneath the tensor fascia lata. Occasionally
tendinous damage may result from acute local direct trauma
or a hyperadductive strain injury. We describe MR imaging in
2 patients with chronic lateral hip pain.
CASE 1
A 74-year-old-female presented with a 6-month history of pain
on the lateral aspect of the left hip joint. T-weighted axial MRI
showed atrophy and partial fat replacement of the left gluteus
medius with some atrophy and fat infiltration of both gluteus
mediuus and minimus muscles (Fig. 1a) T2-weighted coronal
images showed marked distension of subgluteus maximus and
medius bursae. The gluteus medius tendon showed thickening
and increased signal intensity proximally and attenuation distally,
appearances consistent with tendinopathy/partial tear (Fig. 1b).
CASE 2
A 72-year-old woman presented with a long history of dis-
comfort on the lateral aspect of the right hip joint. T2-weighted
coronal MRI showed increased signal intensity surrounding
gluteus minimus and discontinuity of the tendon at its insertion
onto the greater trochanter. High signal intensity consistent with
fluid was also evident surrounding the gluteus medius tendon
(Fig. 2a). T1-weighted coronal images with fat suppression
post-intravenous administration of gadopentetate dimeglumine
(Magnevist; Schering, Berlin, Germany) showed a complete
tear of the gluteus minimus tendon (Fig. 2b) and a partial tear of
gluteus medius tendon with peritendinous synovial enhance-
ment (Fig. 2c).
DISCUSSION AND CONCLUSION
Pain on the lateral aspect of the hip joint is a common clinical
presentation the differential diagnosis of which includes local
trauma, hip joint osteoarthrosis, avascular necrosis of the
femoral head and degenerative spinal disease.

The greater
trochanteric pain syndrome refers to pain on the lateral aspect
of the hip joint and is frequently attributed to trochanteric
bursitis with fluid distension of the bursae.

G WALSH AND CG ARCHIBALD
In 1961, Gordon stated that the primary lesion in ‘trochan-
teric bursitis’ was damage to the gluteal tendons at their
insertion onto the greater trochanter and that the adjacent
bursae were involved secondarily.
2
A number of reports from
the orthopaedic literature have described tears of the gluteus
medius and minimus tendons observed during hip joint sur-
gery. Bunker
et al
. described tears of the gluteus medius and
minimus tendons in 11 of 50 consecutive patients with femoral
neck fractures.
3
Kagan described partial tears of the gluteus
medius tendon at its trochanteric insertion in seven patients
with refractory symptoms undergoing iliotibial band release.

The greater trochanteric pain syndrome is seen most
frequently in middle-aged to elderly women but has been
described more recently in recreational runners and in those
who perform step aerobics.
4,5
An acute syndrome might result
from severe local trauma or from a hyperadductive strain
injury.
6
When conservative treatment fails, surgery to release
the iliotibial band has been advocated.
5
Surgical options range
from transverse fascial release to fascial windowing with or
without reattachment of the gluteal tendons to the greater
trochanter.

(a) T1 weighted axial sequence showed atrophy with partial
fat replacement of the left gluteus medius muscle (arrow) with some fat
infiltration of the gluteus minimus muscle bilaterally. (b) T2-weighted
coronal image showing marked distension of the subgluteus maximus
and subgluteus medius bursae with thickening and increased signal
intensity of the gluteus medius tendon proximally and attenuation
distally (arrows), with appearances consistent with tendinopathy/
partial tear.

weighted coronal image with fat suppression post-intravenous adminis-
tration of gadopentetate dimeglumine showing a complete tear of the
gluteus minimus tendon (arrow; b) and a high grade tear of the gluteus
medius tendon (arrowhead; c) together with peritendinous synovial
enhancement.
GREATER TROCHANTER PAIN SYNDROME
87
Imaging has traditionally played a limited role in the diag-
nosis of the greater trochanteric pain syndrome.
7
Plain
radiographs might show calcification at the trochanteric inser-
tion of the gluteal tendons or irregularity and sclerosis of the
greater trochanter.
8,9
A characteristic scintigraphic appearance
has been described as a linear band of increased tracer uptake
on the superior and lateral aspect of the greater trochanter
on blood pool and delayed images.
10
More recently, Kingzett-
Taylor
et al
. described gluteal tendon tears in 22 cases and
appearances consistent with tendinopathy in 13 of 250 patients
undergoing MRI evaluation for buttock, lateral hip and groin
pain.
6
We found appearances consistent with tendinopathy
and partial tear of gluteus medius and muscle atrophy together
with associated distension of the subgluteus maximus bursa in
one patient while our other case showed gluteus medius and
minimus tendon tears with surrounding synovial enhancement.
In conclusion, we suggest that MRI evaluation for greater
trochanteric pain syndrome should include assessment for both
bursal distension, evidence of tendinopathy and tears involving
gluteus medius and minimus. Recognition of atrophy and fatty
replacement of the gluteus medius and minimus muscles
should prompt a review of the tendon insertions for signs of
tendinopathy and tears. This syndrome has not received much
attention in the radiological literature to date and increased
familiarity with the imaging signs will probably result in diag-
nosis of a greater number of cases.
