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. 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.Aims
Patients and Methods
The number of rotator cuff repairs that are undertaken is increasing. Reverse shoulder arthroplasty (RSA) is the procedure of choice for patients with rotator cuff arthropathy. We sought to determine whether patients who underwent rotator cuff repair and subsequent RSA had different outcomes compared with a matched control group who underwent RSA without a previous rotator cuff repair. All patients with a history of rotator cuff repair who underwent RSA between 2000 and 2015 with a minimum follow-up of two years were eligible for inclusion as the study group. Outcomes, including the American Shoulder and Elbow Surgeons (ASES) scores, were compared with a matched control group of patients who underwent RSA without having previously undergone rotator cuff repair.Aims

Resection of the proximal humerus for the primary malignant bone
tumour sometimes requires We reviewed 45 patients who had undergone resection of a primary
malignant tumour of the proximal humerus. There were 29 in the deltoid
sparing group and 16 in the deltoid resecting group. Imaging studies
were reviewed to assess tumour extension and soft-tissue involvement.
The presence of a fat rim separating the tumour from the deltoid
on MRI was particularly noted. The cumulative probability of local
recurrence was calculated in a competing risk scenario.Aims

The aim of this study was to evaluate the clinical and radiological
outcome of using an anatomical short-stem shoulder prosthesis to
treat primary osteoarthritis of the glenohumeral joint. A total of 66 patients (67 shoulders) with a mean age of 76 years
(63 to 92) were available for clinical and radiological follow-up

Patients and Methods
Controversy about the use of an anatomical total shoulder arthroplasty
(aTSA) in young arthritic patients relates to which is the ideal
form of fixation for the glenoid component: cemented or cementless.
This study aimed to evaluate implant survival of aTSA when used
in patients aged < 60 years with primary glenohumeral osteoarthritis (OA),
and to compare the survival of cemented all-polyethylene and cementless
metal-backed glenoid components. A total of 69 consecutive aTSAs were performed in 67 patients
aged < 60 years with primary glenohumeral OA. Their mean age
at the time of surgery was 54 years (35 to 60). Of these aTSAs,
46 were undertaken using a cemented polyethylene component and 23
were undertaken using a cementless metal-backed component. The age, gender,
preoperative function, mobility, premorbid glenoid erosion, and
length of follow-up were comparable in the two groups. The patients
were reviewed clinically and radiographically at a mean of 10.3
years (5 to 12, Aims

Patients and Methods
Promising medium-term results from total shoulder arthroplasty
(TSA) have been reported for the treatment of primary osteoarthritis
in young and middle-aged patients. The aim of this study was to
evaluate the long-term functional and radiological outcome of TSA
in the middle-aged patient. The data of all patients from the previous medium-term study
were available. At a mean follow-up of 13 years (8 to 17), we reviewed
21 patients (12 men, nine women, 21 shoulders) with a mean age of
55 years (37 to 60). The Constant-Murley score (CS) with its subgroups
and subjective satisfaction were measured. Radiological signs of implant
loosening were analysed.Aims
Patients and 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
Heterotopic ossification (HO) occurs after arthroplasty, especially
total hip arthroplasty. In this study we describe the incidence,
evolution, morphology and clinical consequences of HO following
reverse shoulder arthroplasty. This is a single-centre retrospective study of 132 consecutive
patients who received a Delta III or Delta Xtend reverse total shoulder
arthroplasty between 2006 and 2013 for the treatment of cuff tear
arthropathy. There were 96 women and 36 men. Their mean age at the
time of surgery was 69 years (49 to 89) and the mean follow-up was
36 months (12 to 84). The incidence, evolution, morphology and clinical
consequences of HO using the Constant-Murley score (CS) were analysed.
A modified Brooker classification of HO of the hip was used.Aims

The treatment of septic arthritis of the shoulder is challenging.
The infection frequently recurs and the clinical outcome can be
very poor. We aimed to review the outcomes following the use of
continuous negative pressure after open debridement with a large
diameter drain in patients with septic arthritis of the shoulder. A total of 68 consecutive patients with septic arthritis of the
shoulder underwent arthrotomy, irrigation and debridement. A small
diameter suction drain was placed in the glenohumeral joint and
a large diameter drain was placed in the subacromial space with
continuous negative pressure of 15 cm H2O. All patients
received a standardised protocol of antibiotics for a mean of 5.1
weeks (two to 11.1).Aims
Patients and Methods
Radiological changes and differences between cemented and uncemented components of Grammont reverse shoulder arthroplasties (DePuy) were analysed at a mean follow-up of 9.6 years (8 to 12). Of 122 reverse shoulder arthroplasties implanted in five shoulder centres between 1993 and 2000, a total of 68 (65 patients) were available for study. The indications for reversed shoulder arthroplasty were cuff tear arthropathy in 48 shoulders, revision of shoulder prostheses of various types in 11 and massive cuff tear in nine. The development of scapular notching, bony scapular spur formation, heterotopic ossification, glenoid and humeral radiolucencies, stem subsidence, radiological signs of stress shielding and resorption of the tuberosities were assessed on standardised true anteroposterior and axillary radiographs. A scapular notch was observed in 60 shoulders (88%) and was associated with the superolateral approach (p = 0.009). Glenoid radiolucency was present in 11 (16%), bony scapular spur and/or ossifications in 51 (75%), and subsidence of the stem and humeral radiolucency in more than three zones were present in three (8.8%) and in four (11.8%) of 34 cemented components, respectively, and in one (2.9%) and two (5.9%) of 34 uncemented components, respectively. Radiological signs of stress shielding were significantly more frequent with uncemented components (p <
0.001), as was resorption of the greater (p <
0.001) and lesser tuberosities (p = 0.009).
We present the medium-term clinical results of a reverse total
shoulder arthroplasty with a trabecular metal glenoid base plate. We reviewed 125 consecutive primary reverse total shoulder arthroplasties
(RTSA) implanted in 124 patients for rotator cuff arthropathy. There
were 100 women and 24 men in the study group with a mean age of
76 years (58 to 89). The mean follow-up was 32 months (24 to 60).
No patient was lost to follow-up.Aim
Patients and Methods
If a modular convertible total shoulder system
is used as a primary implant for an anatomical total shoulder arthroplasty,
failure of the prosthesis or the rotator cuff can be addressed by
converting it to a reverse shoulder arthroplasty (RSA), with retention
of the humeral stem and glenoid baseplate. This has the potential
to reduce morbidity and improve the results. In a retrospective study of 14 patients (15 shoulders) with a
mean age of 70 years (47 to 83) we reviewed the clinical and radiological
outcome of converting an anatomical shoulder arthroplasty (ASA)
to a RSA using a convertible prosthetic system (SMR system, Lima,
San Daniele, Italy). The mean operating time was 64 minutes (45 to 75). All humeral
stems and glenoid baseplates were found to be well-fixed and could
be retained. There were no intra-operative or early post-operative
complications and no post-operative infection. The mean follow-up was 43 months (21 to 83), by which time the
mean visual analogue scale for pain had decreased from 8 pre-operatively
to 1, the mean American Shoulder and Elbow Surgeons Score from 12
to 76, the mean Oxford shoulder score from 3 to 39, the mean Western
Ontario Osteoarthritis of the Shoulder Score from 1618 to 418 and
the mean Subjective shoulder value from 15 to 61. On radiological review, one patient had a lucency around the
humeral stem, two had stress shielding. There were no fatigue fractures
of the acromion but four cases of grade 1 scapular notching. The use of a convertible prosthetic system to revise a failed
ASA reduces morbidity and minimises the rate of complications. The
mid-term clinical and radiological results of this technique are
promising. Cite this article:
The June 2012 Shoulder &
Elbow Roundup360 looks at: reverse shoulder replacement; torn rotator cuffs and platelet-rich fibrin; rotator cuff repair; frozen shoulder; whether an arthroscopic rotator cuff repair actually heals; the torn rotator cuff’s effect on activities of daily living; subacromial impingement; how to improve the reliability of the Constant-Murley score; and failure of the Neer modification of an open Bankart procedure.
The combination of an irreparable tear of the rotator cuff and destructive arthritis of the shoulder joint may cause severe pain, disability and loss of independence in the aged. Standard anatomical shoulder replacements depend on a functioning rotator cuff, and hence may fail in the presence of tears in the cuff. Many designs of non-anatomical constrained or semi-constrained prostheses have been developed for cuff tear arthropathy, but have proved unsatisfactory and were abandoned. The DePuy Delta III reverse prosthesis, designed by Grammont, medialises and stabilises the centre of rotation of the shoulder joint and has shown early promise. This study evaluated the mid-term clinical and radiological results of this arthroplasty in a consecutive series of 50 shoulders in 43 patients with a painful pseudoparalysis due to an irreparable cuff tear and destructive arthritis, performed over a period of seven years by a single surgeon. A follow-up of 98% was achieved, with a mean duration of 39 months (8 to 81). The mean age of the patients at the time of surgery was 81 years (59 to 95). The female to male ratio was 5:1. During the seven years, six patients died of natural causes. The clinical outcome was assessed using the American Shoulder and Elbow score, the Oxford Shoulder Score and the Short-form 36 score. A radiological review was performed using the Sirveaux score for scapular notching. The mean American Shoulder and Elbow score was 19 (95% confidence interval (CI) 14 to 23) pre-operatively, and 65 (95% CI 48 to 82) (paired The mean maximum elevation improved from 55° pre-operatively to 105° at final follow-up. There were seven complications during the whole series, although only four patients required further surgery.
Short uncemented humeral stems can preserve humeral
bone stock and facilitate revision surgery but may be prone to malalignment
or loosening, especially when used in reverse total shoulder replacement
(TSR). We undertook a retrospective review of 44 patients with a
mean age of 76 years (59 to 92) who underwent primary reverse TSR
with a short uncemented humeral stem. There were 29 females. The
indications for joint replacement included cuff tear associated
arthropathy (33), avascular necrosis (six), post-traumatic arthritis
(two), and inflammatory arthritis (three). At a mean follow-up of
27 months (24 to 40), pain was rated as mild or none in 43 shoulders
(97.7%). The mean active elevation improved from 54° Cite this article:
We describe the early results of glenoplasty as part of the technique of operative reduction of posterior dislocation of the shoulder in 29 children with obstetric brachial plexus palsy. The mean age at operation was five years (1 to 18) and they were followed up for a mean of 34 months (12 to 67). The mean Mallet score increased from 8 (5 to 13) to 12 (8 to 15) at final follow-up (p <
0.001). The mean passive forward flexion was increased by 18° (p = 0.017) and the mean passive abduction by 24° (p = 0.001). The mean passive lateral rotation also increased by 54° (p <
0.001), but passive medial rotation was reduced by a mean of only 7°. One patient required two further operations. Glenohumeral stability was achieved in all cases.
An internal rotation contracture is a common complication of obstetric brachial plexus palsy. We describe the operative treatment of seven children with a recurrent internal rotation contracture of the shoulder following earlier corrective surgery which included subscapularis slide and latissimus dorsi transfer. We performed z-lengthening of the tendon of the subscapularis muscle and transferred the lower trapezius muscle to the infraspinatus tendon. Two years postoperatively the mean gain in active external rotation was 47.1°, which increased to 54.3° at four years. Lengthening of the tendon of subcapularis and lower trapezius transfer to infraspinatus improved the range of active external rotation in patients who had previously had surgery for an internal rotation contracture.
