Aims. This study aimed to determine the minimal detectable change (MDC), minimal clinically important difference (MCID), and substantial clinical benefit (SCB) under distribution- and anchor-based methods for the Mayo Elbow Performance Index (MEPI) and
Scapular notching is a frequently observed radiographic phenomenon
in reverse shoulder arthroplasty (RSA), signifying impingement of
components. The purposes of this study were to evaluate the effect
of glenoid component size and glenosphere type on impingement-free
range of movement (ROM) for extension and internal and external
rotation in a virtual RSA model, and to determine the optimal configuration
to reduce the incidence of friction-type scapular notching. Preoperative CT scans obtained in 21 patients (three male, 18
female) with primary osteoarthritis were analyzed using modelling
software. Two concurrent factors were tested for impingement-free
ROM and translation of the centre of rotation: glenosphere diameter

Materials and Methods
Aims. Ultrasound (US)-guided injections are widely used in patients with conditions of the shoulder in order to improve their accuracy. However, the clinical efficacy of US-guided injections compared with blind injections remains controversial. The aim of this study was to compare the accuracy and efficacy of US-guided compared with blind corticosteroid injections into the glenohumeral joint in patients with primary frozen shoulder (FS). Methods. Intra-articular corticosteroid injections were administered to 90 patients primary FS, who were randomly assigned to either an US-guided (n = 45) or a blind technique (n = 45), by a shoulder specialist. Immediately after injection, fluoroscopic images were obtained to assess the accuracy of the injection. The outcome was assessed using a visual analogue scale (VAS) for pain, the American Shoulder and Elbow Surgeons (ASES) score, the subjective shoulder value (SSV) and
Aims. The purpose of this study was to determine whether there were long-term differences in outcomes of reverse shoulder arthroplasty (RSA) undertaken for acute proximal humeral fracture versus rotator cuff deficiency with a minimum follow-up of five years. Methods. This was a prospective cohort study comparing 67 patients with acute complex proximal humeral fracture and 64 patients with irreparable rotator cuff deficiency who underwent primary RSA. In the fracture group, there were 52 (77.6%) females and 15 (22.4%) males, with a mean age of 73.5 years (51 to 85), while in the arthropathy group, there were 43 (67.1%) females and 21 (32.9%) males, with a mean age of 70.6 years (50 to 84). Patients were assessed by the Constant score, University of California Los Angeles shoulder score (UCLA), short version of the Disability of the Arm Shoulder and Hand score (QuickDASH), and visual analogue scales (VAS) for pain and satisfaction. Radiological evaluation was also performed. Results. Mean follow-up was 8.4 years (5 to 11). There were no significant differences in mean absolute (p = 0.125) or adjusted (p = 0.569) Constant, UCLA (p = 0.088), QuickDASH (p = 0.135), VAS-pain (p = 0.062), or
Aims. The aim of this study was to report the outcomes of different treatment options for glenoid loosening following reverse shoulder arthroplasty (RSA) at a minimum follow-up of two years. Patients and Methods. We retrospectively studied the records of 79 patients (19 men, 60 women; 84 shoulders) aged 70.4 years (21 to 87) treated for aseptic loosening of the glenosphere following RSA. Clinical evaluation included pre- and post-treatment active anterior elevation (AAE), external rotation, and Constant score. Results. From the original cohort, 29 shoulders (35%) were treated conservatively, 27 shoulders (32%) were revised by revision of the glenosphere, and 28 shoulders (33%) were converted to hemiarthroplasty. At last follow-up, conservative treatment and glenoid revision significantly improved AAE, total Constant score, and pain, while hemiarthroplasty did not improve
Aim. The primary aim of this retrospective study was to identify the
incidence of heterotopic ossification (HO) following elective and
trauma elbow arthroplasty. The secondary aim was to determine clinical
outcomes with respect to the formation of heterotopic ossification. Patients and Methods. A total of 55 total elbow arthroplasties (TEAs) (52 patients)
performed between June 2007 and December 2015 were eligible for
inclusion in the study (29 TEAs for primary elective arthroplasty
and 26 TEAs for trauma). At review, 15 patients (17 total elbow
arthroplasties) had died from unrelated causes. There were 14 men
and 38 women with a mean age of 70 years (42 to 90). The median
clinical follow-up was 3.6 years (1.2 to 6) and the median radiological follow-up
was 3.1 years (0.5 to 7.5). Results. The overall incidence of HO was 84% (46/55). This was higher
in the trauma group (96%, 25/26) compared with the elective arthroplasty
group (72%, 21/29) (p = 0.027, Fisher’s exact test). Patients in
the trauma group had HO of higher Brooker class. The presence of
HO did not significantly affect elbow
Aims. The crucial role of the radial head in the stability of the elbow in terrible triad injury is acknowledged. This retrospective study aims to compare the results of resection of a severely comminuted radial head with or without prosthetic arthroplasty as part of the reconstruction for this injury. Patients and Methods. The outcome of radial head resection was compared with prosthetic arthroplasty in 29 and 15 patients with terrible triad injuries, respectively. There were ten female patients (34.5%) in the resection group and six female patients (40%) in the prosthesis group. The mean age was 40.7 years (. sd. 13.6) in the resection group and 36 years (. sd. 9.4) in the prosthesis group. The mean follow-up of the patients was 24.4 months (. sd. 12) in the resection group and 45.8 months (. sd. 6.8) in the prosthesis group. Outcome measures included visual analogue scale (VAS) for pain, Mayo Elbow Performance Score (MEPS), Disabilities of Arm, Shoulder and Hand (DASH) Score, and
Aim. 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. Patients and Methods. 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
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. Patients and Methods. 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)

Aims. Revision total elbow arthroplasty (TEA) is often challenging.
The aim of this study was to report on the clinical and radiological
results of revision arthroplasty of the elbow with the Latitude
TEA. Patients and Methods. Between 2006 and 2010 we used the Latitude TEA for revision in
18 consecutive elbows (17 patients); mean age 53 years (28 to 80);
14 women. A Kudo TEA was revised in 15 elbows and a Souter-Strathclyde
TEA in three. Stability,
Unlinked, linked and convertible total elbow
arthroplasties (TEAs) are currently available. This study is the
first to report the clinical results of the convertible Latitude
TEA. This was a retrospective study of a consecutive cohort of 63
patients (69 primary TEAs) with a mean age of 60 years (23 to 87).
Between 2006 and 2008 a total of 19 men and 50 women underwent surgery.
The mean follow-up was 43 months (8 to 84). The
Aims. Radial head arthroplasty (RHA) may be used in the treatment of
non-reconstructable radial head fractures. The aim of this study
was to evaluate the mid-term clinical and radiographic results of
RHA. Patients and Methods. Between 2002 and 2014, 77 RHAs were implanted in 54 men and 23
women with either acute injuries (54) or with traumatic sequelae
(23) of a fracture of the radial head. Four designs of RHA were
used, including the Guepar (Small Bone Innovations (SBi)/Stryker;
36), Evolutive (Aston Medical; 24), rHead RECON (SBi/Stryker; ten)
or rHead STANDARD (SBi/Stryker; 7) prostheses. The mean follow-up
was 74.0 months (standard deviation (. sd. ) 38.6; 24 to 141).
The indication for further surgery,
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.

Aims. Cubitus varus is the most common late complication of a supracondylar
fracture of the humerus in children. Correction can be performed
using one of a number of techniques of osteotomy but each has disadvantages.
We describe a new technique for correcting post-traumatic cubitus
varus using a lateral closing wedge isosceles triangular osteotomy. Patients and Methods. A lateral closing wedge isosceles triangular osteotomy was performed
in 25 patients (15 male and ten female with a mean age of 9.5 years
(6 to 12)) between May 2010 and April 2013. All patients had cubitus
varus secondary to malunion of a supracondylar fracture, with good
function of the elbow and a full
Aims. The aim of this study was to analyze the results of reverse shoulder
arthroplasty (RSA) in patients with type 1 sequelae of a fracture
of the proximal humerus in association with rotator cuff deficiency
or severe stiffness of the shoulder. Patients and Methods. A total of 38 patients were included: 28 women and ten men. Their
mean age at the time of arthroplasty was 73 years (54 to 91). Before
the RSA, 18 patients had been treated with open reduction and internal
fixation following a fracture. A total of 22 patients had a rotator
cuff tear and 11 had severe stiffness of the shoulder with < 0°
of external rotation. The mean follow-up was 4.3 years (1.5 to 10).
The Constant score and the
Aims. To date, there is insufficient evidence available to compare
the outcome of cemented and uncemented fixation of the humeral stem
in reverse shoulder arthroplasty (RSA). . Methods. A systemic review comprising 41 clinical studies was performed
to compare the functional outcome and rate of complications of cemented
and uncemented stems in RSA. These included 1455 cemented and 329
uncemented shoulders. The clinical characteristics of the two groups
were similar. Variables were compared using pooled frequency-weighted means
and relative risk ratios (RR). Results. Uncemented stems had a significantly higher incidence of early
humeral stem migration (p <
0.001, RR 18.1, 95% confidence interval
(CI) 5.0 to 65.2) and non-progressive radiolucent lines (p <
0.001, RR 2.4, 95% CI 1.7 to 3.4), but a significantly lower incidence
of post-operative fractures of the acromion compared with cemented
stems (p = 0.004, RR 14.3, 95% CI 0.9 to 232.8). There was no difference
in the risk of stem loosening or revision between the groups. The
cemented stems had a greater relative risk of infection (RR 3.3,
95% CI 0.8 to 13.7), nerve injury (RR 5.7, 95% CI 0.7 to 41.5) and
thromboembolism (RR 3.9, 95% CI 0.2 to 66.6). The functional outcome

We report our experience of performing an elbow
hemiarthroplasty in the treatment of comminuted distal humeral fractures
in the elderly patients. A cohort of 42 patients (three men and 39 women, mean age 72;
56 to 84) were reviewed at a mean of 34.3 months (24 to 61) after
surgery. Functional outcome was measured with the Mayo Elbow Performance
Score (MEPS) and
The outcomes following nonoperative management of minimally displaced greater tuberosity (GT) fractures, and the factors which influence patient experience, remain poorly defined. We assessed the early patient-derived outcomes following these injuries and examined the effect of a range of demographic- and injury-related variables on these outcomes. In total, 101 patients (53 female, 48 male) with a mean age of 50.9 years (19 to 76) with minimally displaced GT fractures were recruited to a prospective observational cohort study. During the first year after injury, patients underwent experiential assessment using the Disabilities of the Arm, Shoulder and Hand (DASH) score and assessment of associated injuries using MRI performed within two weeks of injury. The primary outcome was the one-year DASH score. Multivariate analysis was used to assess the effect of patient demographic factors, complications, and associated injuries, on outcome.Aims
Methods
Our aim was to compare the outcome of arthroscopic
release for frozen shoulder in patients with and without diabetes.
We prospectively compared the outcome in 21 patients with and 21
patients without diabetes, two years post-operatively. The modified
Constant score was used as the outcome measure. The mean age of
the patients was 54.5 years (48 to 65; male:female ratio: 18:24),
the mean pre-operative duration of symptoms was 8.3 months (6 to
13) and the mean pre-operative modified Constant scores were 36.6
(standard deviation (. sd. ) 4.6) and 38.4 (. sd. 5.7)
in the diabetic and non-diabetic groups, respectively. The mean
modified Constant scores at six weeks, six months and two years
post-operatively in the diabetics were 55. 6 (. sd. 4.7),
67. 4 (. sd. 5.6) and 84. 4 (. sd. 6.8), respectively;
and in the non-diabetics 66.8 (. sd. 4.5), 79.6 (. sd. 3.8)
and 88.6 (. sd. 4.2), respectively. A total of 15 (71%) of diabetic
patients recovered a full
Some surgeons are reluctant to perform a reverse
total shoulder arthroplasty (RTSA) on both shoulders because of concerns
regarding difficulty with activities of daily living post-operatively
as a result of limited rotation of the shoulders. Nevertheless,
we hypothesised that outcomes and patient satisfaction following
bilateral RTSA would be comparable to those following unilateral
RTSA. A single-surgeon RTSA registry was reviewed for patients who underwent
bilateral staged RTSA with a minimum follow-up of two years. A unilateral
RTSA matched control was selected for each shoulder in those patients
undergoing bilateral procedures. The Constant–Murley score (CMS), American
Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Values
(SSV), visual analogue scale (VAS) for pain,
