The aim of this study was to describe a quantitative 3D CT method to measure rotator cuff muscle volume, atrophy, and balance in healthy controls and in three pathological shoulder cohorts. In all, 102 CT scans were included in the analysis: 46 healthy, 21 cuff tear arthropathy (CTA), 18 irreparable rotator cuff tear (IRCT), and 17 primary osteoarthritis (OA). The four rotator cuff muscles were manually segmented and their volume, including intramuscular fat, was calculated. The normalized volume (NV) of each muscle was calculated by dividing muscle volume to the patient’s scapular bone volume. Muscle volume and percentage of muscle atrophy were compared between muscles and between cohorts.Aims
Methods
The purpose of this study was to identify the changes in untreated long head of the biceps brachii tendon (LHBT) after a rotator cuff tear and to evaluate the factors related to the changes. A cohort of 162 patients who underwent isolated supraspinatus with the preservation of LHBT was enrolled and evaluated. The cross-sectional area (CSA) of the LHBT on MRI was measured in the bicipital groove, and preoperative to postoperative difference was calculated at least 12 months postoperatively. Second, postoperative changes in the LHBT including intratendinous signal change, rupture, dislocation, or superior labral lesions were evaluated with seeking of factors that were correlated with the changes or newly developed lesions after rotator cuff repair.Aims

Aims. Failure of healing is a well-known problem after repair of the rotator cuff. This study aimed to investigate if early repair of trauma-related full-thickness rotator cuff tears (FTRCTs) could prevent this failure. Patients and Methods. In this prospective trial, 62 consecutive patients (14 women (23%), 48 men (77%); median age 61 years (interquartile range (IQR) 54 to 65)) with trauma-related FTRCT underwent arthroscopic single-row repair within six weeks of trauma. Tendon integrity was assessed one year after surgery using the Sugaya score on
The aim of the study was to develop a quantitative scoring system
to predict whether a large-to-massive rotator cuff tear was arthroscopically
reparable prior to surgery. We conducted a retrospective review of the pre-operative MR imaging
and surgical records of 87 patients (87 shoulders) who underwent
arthroscopic repair of a large-to-massive rotator cuff tear. Patients
were divided into two groups, based on the surgical outcome of the
repair. Of the 87 patients, 53 underwent complete repair (Group
I) and 34 an incomplete repair (Group II). Pre-operative MR images
were reviewed to quantify several variables. Between-group differences
were evaluated and multiple logistic regression analysis was used
to calculate the predictive value of significant variables. The
reparability index (RI) was constructed using the odds ratios of
significant variables and a receiver operating characteristic curve
analysis performed to identify the optimal RI cutoff to differentiate
between the two groups.Aims
Patients and Methods
This study compared the clinical outcomes following
mini-open rotator cuff repair (MORCR) between early mobilisation
and usual care, involving initial immobilisation. In total, 189
patients with radiologically-confirmed full-thickness rotator cuff
tears underwent MORCR and were randomised to either early mobilisation
(n = 97) or standard rehabilitation (n = 92) groups. Patients were
assessed at six weeks and three, six, 12 and 24 months post-operatively.
Six-week range of movement comparisons demonstrated significantly
increased abduction (p = 0.002) and scapular plane elevation (p
= 0.006) in the early mobilisation group, an effect which was not
detectable at three months (p >
0.51) or afterwards. At 24 months
post-operatively, patients who performed pain-free, early active mobilisation
for activities of daily living showed no difference in clinical
outcomes from patients immobilised for six weeks following MORCR.
We suggest that the choice of rehabilitation regime following MORCR
may be left to the discretion of the patient and the treating surgeon. Cite this article:
We have compared three different methods of treating
symptomatic non-traumatic tears of the supraspinatus tendon in patients
above 55 years of age. A total of 180 shoulders (173 patients) with
supraspinatus tendon tears were randomly allocated into one of three
groups (each of 60 shoulders); physiotherapy (group 1), acromioplasty and
physiotherapy (group 2) and rotator cuff repair, acromioplasty and
physiotherapy (group 3). The Constant score was assessed and followed
up by an independent observer pre-operatively and at three, six
and twelve months after the intervention. Of these, 167 shoulders were available for assessment at one
year (follow-up rate of 92.8%). There were 55 shoulders in group
1 (24 in males and 31 in females, mean age 65 years (55 to 79)),
57 in group 2 (29 male and 28 female, mean age 65 years (55 to 79))
and 55 shoulders in group 3 (26 male and 29 female, mean age 65
years (55 to 81)). There were no between-group differences in the
Constant score at final follow-up: 74.1 ( Cite this article:
