The aim of this study was to assess hypertrophy of the extra-articular
tendon of the long head of biceps (LHB) in patients with a rotator
cuff tear. The study involved 638 shoulders in 334 patients (175 men, 159
women, mean age 62.6 years; 25 to 81) with unilateral symptomatic
rotator cuff tears. The cross-sectional area (CSA) of the LHB tendon
in the bicipital groove was measured pre-operatively in both shoulders
using ultrasound. There were 154 asymptomatic rotator cuff tears
in the contralateral shoulder. Comparisons were made between those
with a symptomatic tear, an asymptomatic tear and those with no
rotator cuff tear. In the affected shoulders, the CSAs were compared
in relation to the location and size of the rotator cuff tear. Aims
Patients and Methods
This retrospective study was designed to evaluate
the outcomes of re-dislocation of the radial head after corrective osteotomy
for chronic dislocation. A total of 12 children with a mean age
of 11 years (5 to 16), with further dislocation of the radial head
after corrective osteotomy of the forearm, were followed for a mean
of five years (2 to 10). Re-operations were performed for radial
head re-dislocation in six children, while the other six did not
undergo re-operation (‘non-re-operation group’). The active range
of movement (ROM) of their elbows was evaluated before and after
the first operation, and at the most recent follow-up. In the re-operation group, there were significant decreases in
extension, pronation, and supination when comparing the ROM following
the corrective osteotomy and following
re-operation (p <
0.05). The children who had not undergone re-operation achieved a better
ROM than those who had undergone re-operation. There was a significant difference in mean pronation (76° Cite this article:
We conducted a prospective follow-up MRI study
of originally asymptomatic healthy subjects to clarify the development
of Modic changes in the cervical spine over a ten-year period and
to identify related factors. Previously, 497 asymptomatic healthy
volunteers with no history of cervical trauma or surgery underwent
MRI. Of these, 223 underwent a second MRI at a mean follow-up of
11.6 years (10 to 12.7). These 223 subjects comprised 133 men and 100
women with a mean age at second MRI of 50.5 years (23 to 83). Modic
changes were classified as not present and types 1 to 3. Changes
in Modic types over time and relationships between Modic changes
and progression of degeneration of the disc or clinical symptoms
were evaluated. A total of 31 subjects (13.9%) showed Modic changes at
follow-up: type 1 in nine, type 2 in 18, type 3 in two, and types In the cervical spine over a ten-year period
We studied degenerative changes in the cervical intervertebral discs of 497 asymptomatic subjects by MRI and evaluated disc degeneration by loss of signal intensity, posterior and anterior disc protrusion, narrowing of the disc space and foraminal stenosis. In each subject, five disc levels from C2–C3 to C6–C7 were evaluated. The frequency of all degenerative findings increased linearly with age. Disc degeneration was the most common observation, being present in 17% of discs of men and 12% of those of women in their twenties, and 86% and 89% of discs of both men and women over 60 years of age. We found significant differences in frequency between genders for posterior disc protrusion and foraminal stenosis. The former, with demonstrable compression of the spinal cord, was observed in 7.6% of subjects, mostly over 50 years of age. Our results should be taken into account when interpreting the MRI findings in patients with symptomatic disorders of the cervical spine.
