Progressive arthritis can occur in association with massive tears of the rotator cuff. Altered joint kinematics are commonly proposed as the principle causative factor but this does not explain the absence of arthropathy in some patients.

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

Background. Absence of rotator cuff allows unbalanced muscle forces of the shoulder to cause vertical migration of the humeral head. The translation of the humerus causes impaction of articular surface against the acromion. The purpose of the study is to assess outcome of

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

Cementless surface replacement arthroplasty (CSRA) is an established treatment for glenohumeral osteoarthritis. Few studies however, evaluate its role in cuff tear arthopathy. The purpose of this study is to compare the outcomes of CSRA for both glenohumeral osteoarthritis and cuff tear arthopathy. 42 CSRA with the Mark IV Copeland prosthesis were performed for glenohumeral osteoarthritis (n=21) or cuff tear arthopathy (n=21). Patients were assessed with Oxford and Constant scores, patient satisfaction, range of motion and radiologically with plain radiographs. Mean follow-up and age was 5.2 years and 74 years in both groups. Functional outcomes were significantly higher in OA compared with CTA with OSS improving from 18 to 37.5 and 15 to 26 in both groups respectively. Forward flexion improved from 60° to 126° and 42° to 74° in both groups. Three patients in the CTA group had a deficient subscapularis tendon, two of whom dislocated anteriorly. Humeral head resurfacing arthroplasty is a viable treatment option for glenohumeral osteoarthritis. In patients with CTA, functional gains are limited. We suggest CSRA should be considered in low demand patients where pain is the primary problem. Caution should be taken in patients with a deficient subscapularis due to the high risk of dislocation.
The purpose of this study was to evaluate the short to mid-term results after hemiarthroplasty with extended head prosthesis (CTA head) for patients with cuff tear arthopathy. Favorable pain reduction would be obtained after hemiarthroplasty with the extended head design.Purpose
Hypothesis
Rotator cuff arthropathy is a challenging problem to treat in many patients whose function remains intact despite pain from arthritis. In recent years, the introduction of reverse shoulder arthroplasty has improved the function and pain in pseudoparalytic shoulders with rotator cuff deficiency. However, significant evidence exists to support the use of alternative surgical and non-surgical treatments for those patients who suffer from the pain of arthritis while maintaining an intact force-couple of the rotator cuff and relatively well preserved function.
The treatment of patients with arthritis of the glenohumeral joint with an associated massive irreparable cuff tear is challenging. Since these patients usually have proximal migration of the humerus, the CTA extended head allows a surface with a low coefficient of friction to articulate with the acromion. Between 2001 and 2006 a total of 48 patients with arthritis of the shoulder joint associated with a massive cuff tear, were treated with a CTA head. The indications for use being Seebauer Type 1a and 1b appearances on x-ray and active abduction of the arm to more than 60° with appropriate analgesia. Preoperatively, a Constant score and an ASES pain and function score were completed as well as standard radiological assessment. These were repeated at follow up. Paired t tests were carried out for all the variables. A Kaplan-Meier survival analysis was performed. Follow up varied between 2 and 8 years. Improvements in pain, function and all movement parameters were significant at p<
0.001. There was no change in the strength component. Survival analysis showed 94% survival at 8 years (95% CL 8%) there were 2 revisions and 5 deaths. Radiological assessment at follow up revealed no evidence of humeral stem loosening. In 5 (17%) cases however there was evidence of erosion in the surface of the acromion and in 13 (45%) erosion of the glenoid. Finally one component was also seen to have subluxed anteriorly. This head design has been in use for a number of years. To date there appears to be no reported outcome of their use. This series shows that in an appropriately selected patient a satisfactory clinical outcome can be maintained in the short to medium term. The presence of erosion of the glenoid but also the under surface of the acromion does require continuing monitoring.
Aims. The current evidence comparing the two most common approaches for reverse total shoulder arthroplasty (rTSA), the deltopectoral and anterosuperior approach, is limited. This study aims to compare the rate of loosening, instability, and implant survival between the two approaches for rTSA using data from the Dutch National Arthroplasty Registry with a minimum follow-up of five years. Methods. All patients in the registry who underwent a primary rTSA between January 2014 and December 2016 using an anterosuperior or deltopectoral approach were included, with a minimum follow-up of five years. Cox and logistic regression models were used to assess the association between the approach and the implant survival, instability, and glenoid loosening, independent of confounders. Results. In total, 3,902 rTSAs were included. A deltopectoral approach was used in 54% (2,099/3,902) and an anterosuperior approach in 46% (1,803/3,902). Overall, the mean age in the cohort was 75 years (50 to 96) and the most common indication for rTSA was

In recently, reverse shoulder arthroplasty for rotator cuff deficient arthritis is widely used in the world. However, a high complication rate was reported and worried about long-term results after reverse shoulder arthroplasty. From 2001, we performed a novel strategy for these cases such as rotator cuff reconstruction w/ or w/o muscle transfer and a humeral head replacement with using smallest head to decrease joint volume. The aim of this study was to investigate with clinical outcomes after this surgery more than two years follow-up. Materials & methods.

A retrospective cohort study which looked at patients who underwent CRHA over 6 years. Re-operations including revisions with component exchange taking place in our hospital and at local centres were reviewed. Oxford Shoulder Score (OSS) was used to assess their functional outcomes pre- and post-CRHA. Results. 80 CRHAs were performed in 72 patients between 2007 and 2013 with a mean follow-up of 6.5 years. The mean follow-up was 79 months (50–122). The primary indication for CRHA was osteoarthritis (76.3%),
Introduction. Acromial and scapular fractures are a rare but difficult complication with reverse total shoulder arthroplasty (rTSA), with an incidence rate reported from 1–10%. The risk factors associated with these fractures types is largely unknown. The goal of this study is to analyze the clinical outcomes, demographic and comorbidity data, and implant sizing and surgical technique information from 4125 patients who received a primary rTSA with one specific prosthesis (Equinoxe, Exactech, Inc) and were sorted based on the radiographic documentation of an acromial and/or scapula fracture (ASF) to identify factors associated with this complication. Methods. 4125 patients (2652F/1441M/32 unspecified; mean age: 72.5yrs) were treated with primary rTSA by 23 orthopaedic surgeons. Revision and fracture reverse arthroplasty cases were excluded. The radiographic presence of each fracture was documented and classified using the Levy classification method. 61 patients were identified as having ASF, 10 patients had fractures of the Type 1, 32 patients had Type 2, and 18 patients had Type 3 fractures according to Levy's classification. One fracture was not classifiable. Pre-op and post-op outcome scoring, ROM as well as demographic, comorbidity, implant, and surgical technique information were evaluated for these 61 patients and compared to the larger cohort of patients to identify any associations. A two-tailed, unpaired t-test identified differences (p<0.05). Results. The overall rate of ASF was 1.48% with the average time after surgery occurring at 12.9 ± 17.9 months (range 1 day to 78 months). Men had an ASF rate of 0.69% (10 of 1441); whereas women had a rate of 1.92% (51 of 2652). Patients with ASF were observed to be significantly shorter than patients without ASF (65.1 in vs 63.3 in, p=0.0004). ASF were more common in females (p=0.0019), have Rheumatoid Arthritis (p=0.0051),

Background. The use of reverse total shoulder arthroplasty considerably increased since first introduced by Paul Grammont in the late 1980s. Over the past few years, results from several mid- and long-term clinical studies have demonstrated good functional outcomes and pain relief. However, several complications, especially inferior glenoid notching, and high revision rates were reported in the literature. Improvements in prosthesis design should contribute to a lower complication rate and lesser amount of glenoid erosion. Few studies have reported the clinical outcome andcomplications of Anatomical Shoulder Inverse/ Reverse Prosthesis. This study documents 2- and 6-year clinical and radiological results following reversed shoulder arthroplasty using this novel prosthesis. Methods. We report the results for sixty-eight consecutive patients (seventy shoulders) with

We undertook 37 reverse total shoulder replacements within a 2 yr period for chronic complex shoulder conditions. All cases were undertook by one of two upper limb consultant orthopaedic surgeons. At time of listing for operation, the decision as to whether to undertake a bony-increased offset reverse total shoulder was made. Retrospective data was collected on the need for analgesia at final follow up and range of movement. Of the 37 patients, 12 underwent BIO-RSA procedures. Indications for surgery was predominantly rotator cuff arthropathy (n=9) but two patients had severe OA and one had a complex proximal humeral fracture. The average age of the patient was 76.6 yrs (69–87 yrs) with a mean follow-up of 6.8 months (6 weeks to 1 yr). The remaining 25 patients were similar in terms of indication, with 18 patients with

Reverse total shoulder arthroplasty (RTSA) is a well established treatment that provides reproducible results in the treatment of shoulder arthritis and rotator cuff deficiency in the older patient population. However, the results of arthroplasty in younger, more active patients are currently unclear and not as predictable. The purpose of this study is to evaluate the mid-term results of RTSA for patients aged younger than 60 years. A retrospective review of twenty-six patients (twenty six RTSAs) with a mean age of 58.3 years was performed. Minimum follow-up of 5 years was available at a mean follow-up of 73.3 months postoperatively (range, 60–84 months). The preoperative conditions compelling RTSA were as follows: failed rotator cuff repair (17), fracture sequelae (5), failed arthroplasty (1), and

Despite reverse total shoulder arthroplasty (RTSA) being primarily indicated for massive rotator cuff tears, it is often possible to repair portions of the infraspinatus and subscapularis of patients undergoing this procedure. However, there is disagreement regarding whether these tissues should be repaired, as their effects remain unclear. Therefore, we investigated the effects of rotator cuff repair and changes in humeral and glenosphere lateralisation (HLat & GLat) on deltoid and joint loading. Six shoulders were tested on an in-vitro muscle driven active motion simulator.
