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
Metabolic syndrome and low-grade systemic inflammation are associated with knee osteoarthritis (OA), but the relationships between these factors and OA in other synovial joints are unclear. The aim of this study was to determine if a high-fat/high-sucrose (HFS) diet results in OA-like joint damage in the shoulders, knees, and hips of rats after induction of obesity, and to identify potential joint-specific risks for OA-like changes. A total of 16 male Sprague-Dawley rats were allocated to either the diet-induced obesity group (DIO, 40% fat, 45% sucrose, n = 9) or a chow control diet (n = 7) for 12 weeks. At sacrifice, histological assessments of the shoulder, hip, and knee joints were performed. Serum inflammatory mediators and body composition were also evaluated. The total Mankin score for each animal was assessed by adding together the individual Modified Mankin scores across all three joints. Linear regression modelling was conducted to evaluate predictive relationships between serum mediators and total joint damage.Objectives
Methods
Patient-specific glenoid guides (PSGs) claim an improvement in
accuracy and reproducibility of the positioning of components in
total shoulder arthroplasty (TSA). The results have not yet been
confirmed in a prospective clinical trial. Our aim was to assess
whether the use of PSGs in patients with osteoarthritis of the shoulder
would allow accurate and reliable implantation of the glenoid component. A total of 17 patients (three men and 14 women) with a mean age
of 71 years (53 to 81) awaiting TSA were enrolled in the study.
Pre- and post-operative version and inclination of the glenoid were
measured on CT scans, using 3D planning automatic software. During
surgery, a congruent 3D-printed PSG was applied onto the glenoid
surface, thus determining the entry point and orientation of the
central guide wire used for reaming the glenoid and the introduction
of the component. Manual segmentation was performed on post-operative
CT scans to compare the planned and the actual position of the entry
point (mm) and orientation of the component (°).Aims
Patients and Methods
We report the clinical results of glenoid osteotomy in patients
with atraumatic posteroinferior instability associated with glenoid
dysplasia. The study reports results in 211 patients (249 shoulders) with
atraumatic posteroinferior instability. The patients comprised 63
men and 148 women with a mean age of 20 years. The posteroinferior
glenoid surface was elevated by osteotomy at the scapular neck.
A body spica was applied to maintain the arm perpendicular to the
glenoid for two weeks postoperatively. Clinical results were evaluated
using the Rowe score and Japan Shoulder Society Shoulder Instability
Score (JSS-SIS); bone union, osteoarthrosis, and articular congruity
were examined on plain radiographs.Aims
Patients and Methods
The aim of this study was to report the long-term outcome and
implant survival of the lateral resurfacing elbow (LRE) arthroplasty
in the treatment of elbow arthritis. We reviewed a consecutive series of 27 patients (30 elbows) who
underwent LRE arthroplasty between December 2005 and January 2008.
There were 15 women and 12 men, with a mean age of 61 years (25
to 82). The diagnosis was primary hypotrophic osteoarthritis (OA)
in 12 patients (14 elbows), post-traumatic osteoarthritis (PTOA)
in five (five elbows) and rheumatoid arthritis (RA) in ten patients
(11 elbows). The mean clinical outcome scores including the Mayo
Elbow Performance Score (MEPS), the American Shoulder and Elbow
Surgeons elbow score (ASES-e), the mean range of movement and the
radiological outcome were recorded at three, six and 12 months and
at a mean final follow-up of 8.3 years (7.3 to 9.4). A one sample Aim
Patients and Methods
The eccentric glenosphere was principally introduced into reverse
shoulder arthroplasty to reduce the incidence of scapular notching.
There is only limited information about the influence of its design
on deltoid power and joint reaction forces. The aim of our study was to investigate how the diameter and
eccentricity of the glenosphere affect the biomechanics of the deltoid
and the resultant joint reaction forces. Different sizes of glenosphere and eccentricity were serially
tested in ten cadaveric shoulders using a custom shoulder movement
simulator.Aims
Methods
Accurate characterisation of fractures is essential in fracture management trials. However, this is often hampered by poor inter-observer agreement. This article describes the practicalities of defining the fracture population, based on the Neer classification, within a pragmatic multicentre randomised controlled trial in which surgical treatment was compared with non-surgical treatment in adults with displaced fractures of the proximal humerus involving the surgical neck. The trial manual illustrated the Neer classification of proximal humeral fractures. However, in addition to surgical neck displacement, surgeons assessing patient eligibility reported on whether either or both of the tuberosities were involved. Anonymised electronic versions of baseline radiographs were sought for all 250 trial participants. A protocol, data collection tool and training presentation were developed and tested in a pilot study. These were then used in a formal assessment and classification of the trial fractures by two independent senior orthopaedic shoulder trauma surgeons.Objectives
Methods
Failed internal fixation of a fracture of the
proximal humerus produces many challenges with limited surgical options.
The aim of this study was to evaluate the clinical outcomes after
the use of a reverse shoulder arthroplasty under these circumstances.
Between 2007 and 2012, 19 patients (15 women and four men, mean
age 66 years; 52 to 82) with failed internal fixation after a proximal
humeral fracture, underwent implant removal and reverse shoulder arthroplasty
(RSA). The mean follow-up was 36 months (25 to 60). The mean American
Shoulder and Elbow Score improved from 27.8 to 50.1 (p = 0.019).
The mean Simple Shoulder Test score improved from 0.7 to 3.2 (p
= 0.020), and the mean visual analogue scale for pain improved from
6.8 to 4.3 (p = 0.012). Mean forward flexion improved from 58.7°
to 101.1° (p <
0.001), mean abduction from 58.7° to 89.1° (p
= 0.012), mean external rotation from 10.7° to 23.1° (p = 0.043)
and mean internal rotation from buttocks to L4 (p = 0.034). A major
complication was recorded in five patients (26%) (one intra-operative
fracture, loosening of the humeral component in two and two peri-prosthetic
fractures). A total of 15 patients (79%) rated their outcome as
excellent or good, one (5%) as satisfactory, and three (16%) as
unsatisfactory. An improvement in outcomes and pain can be expected when performing
a RSA as a salvage procedure after failed internal fixation of a
fracture of the proximal humerus. Patients should be cautioned about
the possibility for major complications following this technically
demanding procedure. Cite this article:
Few studies have evaluated the relationship between patients’
pre-operative expectations and the outcome of orthopaedic procedures.
Our aim was to determine the effect of expectations on the outcome
after primary anatomical total shoulder arthroplasty (TSA). We hypothesised
that patients with greater expectations would have better outcomes. Patients undergoing primary anatomical TSA completed the Hospital
for Special Surgery’s Shoulder Expectations Survey pre-operatively.
The American Shoulder and Elbow Surgeons (ASES), Shoulder Activity
Scale (SAS), Short-Form-36 (SF-36), and visual analogue scale (VAS)
for pain, fatigue, and general health scores were also collected
pre-operatively and two years post-operatively. Pearson correlations
were used to assess the relationship between the number of expectations
and the outcomes. Differences in outcomes between those with higher
and lower levels of expectations for each expectation were assessed
by independent samples Aims
Patients and Methods
A variety of operative techniques have been described as under
the term ‘Bristow-Latarjet’ procedure. This review aims to define
the original procedure, and compare the variation in techniques
described in the literature, assessing any effect on clinical outcomes. A systematic review of 24 studies was performed to compare specific
steps of the technique (coracoid osteotomy site, subscapularis approach,
orientation and position of coracoid graft fixation and fixation
method, additional labral and capsular repair) and detect any effect
this variability had on outcomes.Objectives
Materials and Methods
Restoring the pre-morbid anatomy of the proximal humerus is a
goal of anatomical shoulder arthroplasty, but reliance is placed
on the surgeon’s experience and on anatomical estimations. The purpose
of this study was to present a novel method, ‘Statistical Shape
Modelling’, which accurately predicts the pre-morbid proximal humeral anatomy
and calculates the 3D geometric parameters needed to restore normal
anatomy in patients with severe degenerative osteoarthritis or a
fracture of the proximal humerus. From a database of 57 humeral CT scans 3D humeral reconstructions
were manually created. The reconstructions were used to construct
a statistical shape model (SSM), which was then tested on a second
set of 52 scans. For each humerus in the second set, 3D reconstructions
of four diaphyseal segments of varying lengths were created. These
reconstructions were chosen to mimic severe osteoarthritis, a fracture
of the surgical neck of the humerus and a proximal humeral fracture
with diaphyseal extension. The SSM was then applied to the diaphyseal
segments to see how well it predicted proximal morphology, using
the actual proximal humeral morphology for comparison.Aims

Manipulation under anaesthetic (MUA) is a recognised form of
treatment for patients with a frozen shoulder. However, not all
patients benefit. Some have persistent or recurrent symptoms. There
are no clear recommendations in the literature on the optimal management
of recurrent frozen shoulder after a MUA. We aimed to address this
issue in this study. We analysed a prospectively collected, single-surgeon, consecutive
series of patients who underwent MUA for frozen shoulder between
January 1999 and December 2015. The Oxford Shoulder Scores (OSS)
and range of movement were the outcome measures. Aims
Patients and Methods
This pilot study reports the clinical outcomes
of a combination of partial subscapularis tendon transfer and small-head
hemiarthroplasty in patients with rotatator cuff arthropathy. A
total of 30 patients (30 shoulders; eight men and 22 women) with
a mean age of 74 years (55 to 84) were assessed at a mean follow-up
of 31 months (24 to 60). The inclusion criteria were painful cuff
tear arthropathy with normal deltoid function and a non-degenerative subscapularis
muscle and tendon and a preserved teres minor. Outcome was assessed using the University of California Los Angeles
score, the Japanese Orthopaedic Association score, and the Oxford
Shoulder Score. Radiographic measurements included the centre of
rotation distance and the length of the deltoid. All clinical scores were significantly improved post-operatively.
The active flexion and external rotation improved significantly
at the most recent follow-up (p <
0.035). Although the mean centre
of rotation distance changed significantly (p <
0.001), the mean
length of the deltoid did not change significantly from the pre-operative
value (p = 0.29). The change in the length of the deltoid with <
100° flexion was significantly less than that with >
100° (p <
0.001). Progressive erosion of the glenoid was seen in four patients.
No patient required revision or further surgery. A combination of partial subscapularis tendon transfer and small-head
hemiarthroplasty effectively restored function and relieved pain
in patients with rotator cuff arthropathy. Cite this article: 2015;97-B:1090–5.
In this study we evaluated whether the Instability
Severity Index Score (ISIS) and the Western Ontario Shoulder Instability
Index (WOSI) could detect those patients at risk of failure following
arthroscopic Bankart repair. Between April 2008 and June 2010, the
ISIS and WOSI were recorded pre-operatively in 110 patients (87
male, 79%) with a mean age of 25.1 years (16 to 61) who underwent
this procedure for recurrent anterior glenohumeral instability. A telephone interview was performed two-years post-operatively
to determine whether patients had experienced a recurrent dislocation
and whether they had returned to pre-injury activity levels. In
all, six (5%) patients had an ISIS >
6 points (0 to 9). Of 100 (91%)
patients available two years post-operatively, six (6%) had a recurrent dislocation,
and 28 (28%) did not return to pre-injury activity. No patient who
dislocated had an ISIS >
6 (p = 1.0). There was no difference in
the mean pre-operative WOSI in those who had a re-dislocation and
those who did not (p = 0.99). The pre-operative WOSI was significantly
lower (p = 0.02) in those who did not return to pre-injury activity, whereas
the ISIS was not associated with return to pre-injury activity (p
= 0.13). In conclusion, neither the pre-operative ISIS nor WOSI predicted
recurrent dislocation within two years of arthroscopic Bankart repair.
Patients with a lower pre-operative WOSI were less likely to return
to pre-injury activity. Cite this article:
Glenoid bone loss can be a challenging problem when revising
a shoulder arthroplasty. Precise pre-operative planning based on
plain radiographs or CT scans is essential. We have investigated
a new radiological classification system to describe the degree
of medialisation of the bony glenoid and that will indicate the
amount of bone potentially available for supporting a glenoid component.
It depends on the relationship between the most medial part of the
articular surface of the glenoid with the base of the coracoid process
and the spinoglenoid notch: it classifies the degree of bone loss
into three types. It also attempts to predict the type of glenoid reconstruction
that may be possible (impaction bone grafting, structural grafting
or simple non-augmented arthroplasty) and gives guidance about whether
a pre-operative CT scan is indicated. Inter-method reliability between plain radiographs and CT scans
was assessed retrospectively by three independent observers using
data from 39 randomly selected patients. Inter-observer reliability and test-retest reliability was tested
on the same cohort using Cohen's kappa statistics. Correlation of
the type of glenoid with the Constant score and its pain component
was analysed using the Kruskal-Wallis method on data from 128 patients.
Anatomical studies of the scapula were reviewed to explain the findings.Aims
Patients and Methods
In this study, we describe a morphological classification
for greater tuberosity fractures of the proximal humerus. We divided
these fractures into three types: avulsion, split and depression.
We retrospectively reviewed all shoulder radiographs showing isolated
greater tuberosity fractures in a Level I trauma centre between
July 2007 and July 2012. We identified 199 cases where records and
radiographs were reviewed and included 79 men and 120 women with
a mean age of 58 years (23 to 96). The morphological classification
was applied to the first 139 cases by three reviewers on two occasions
using the Kappa statistic and compared with the AO and Neer classifications.
The inter- and intra-observer reliability of the morphological classification
was 0.73 to 0.77 and 0.69 to 0.86, respectively. This was superior
to the Neer (0.31 to 0.35/0.54 to 0.63) and AO (0.30 to 0.32/0.59
to 0.65) classifications. The distribution of avulsion, split and
depression type fractures was 39%, 41%, and 20%, respectively. This
classification of greater tuberosity fractures is more reliable
than the Neer or AO classifications. These distinct fracture morphologies
are likely to have implications in terms of pathophysiology and
surgical technique. Cite this article:
Advances in arthroscopic techniques for rotator cuff repair have
made the mini-open approach less popular. However, the mini-open
approach remains an important technique for repair for many surgeons.
The aims of this study were to compare the integrity of the repair,
the function of the shoulder and satisfaction post-operatively using
these two techniques in patients aged >
50 years. We identified 22 patients treated with mini-open and 128 patients
treated with arthroscopic rotator cuff repair of July 2007 and June
2011. The mean follow-up was two years (1 to 5). Outcome was assessed
using the American Shoulder and Elbow Surgeons (ASES) and Simple
Shoulder Test (SST) scores, and satisfaction. The integrity of the repair
was assessed using ultrasonography. A power analysis ensured sufficient
enrolment.Aims
Patients and Methods
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:
