We present a retrospective analysis of 50 cases of cuff tear arthropathy, treated over a seven year period by use of reverse geometry shoulder prosthesis. 98% follow-up was achieved with average follow up of 3 years. Mean (SD) age was 81.3 (9.2) years and female to male ratio was 5:1. Six patients had bilateral reverse geometry shoulder replacements. Patients were assessed with pre-operative American Shoulder and Elbow Score (pre-op ASES) and post-operative American Shoulder and Elbow Scores (post-op ASES), Oxford, Constant and SF36 scores. Mean pre-op ASES was 22.29 (95%CI: 9.1 – 37.9) and post-op ASES score was 65.2 (95%CI: 48.5 – 81.9), (P<
0.001, Paired t-test). Mean post operative Oxford score was 27.25 (95% CI: 18.4 – 27.6). Mean post operative Constant score was 63.2 (95% CI: 52.6 – 79.6). X-ray review was performed to assess scapular notching and Sirveaux score was used to grade extent of notching. 11 patients had Sirveaux grade 0, 5 had grade 1, 6 had grade 2, 12 had grade 3 and 8 had grade 4 notching. Intra-operative complications included 2 glenoid fractures. Post-operative complications included 2 acromion fractures and 2 episodes of subsidence with dislocation. None of the patients developed post operative haematoma. There was one episode of infection in one patient that required further surgery. Iteration of approach with increasing experience over the years will be discussed. Ours is the biggest series of reverse geometry prosthesis used for
The surgical technique for treatment of massive rotator cuff tears, more than 5 cm, with loss of substance and tendon retraction, is still not well defined by the international orthopaedic community. A specific rehabilitation regimen or arthroscopic débridement may be insufficient in active patients who continue to suffer from pain and muscular fatigue in active forward elevation. We treated 20 patients, 14 men and 6 women, with an average age of 52 years (range 40–69) with the surgical technique consisting in acromion decompression, stabilisation of the cuff lesion with anchors, application of a prolene membrane and using a deltoid muscular flap as reinforcement. Deltoid flap is created by splitting the deltoid muscular fibres in front of the anterior border of the acromion. The inferior part of deltoid is sutured to the tendon above the synthetic membrane. The mean patient follow-up was 24 months. The pain was completely relieved in 85% of subjects, The joint mobility increased significantly in flexion, abduction and external rotation; however, the internal rotation did not improve. We propose this surgical technique as the procedure of choice for treating retracted ruptures of the supraspinatus associated with lesions of the supra- and the infra-spinatus.
We wished to assess the usefulness of Inspace balloon arthroplasty (IBA), in our Upper limb unit by regular patient reviews prospectively. This prospective study was started adhering to local approval process. Patients were identified in routine clinical practice by three upper limb consultants presenting with pain and disability and diagnosis of cuff tear was established clinically and on MRI. The patients were explained of ‘available’ treatment options and an information leaflet about balloon arthroplasty provided. Patients were seen in 4 weeks, in a dedicated clinic to find out their willingness to participate. Consultant shoulder surgeons carried out all Balloon arthroplasties and where the cuff was reparable or contraindications identified were excluded from study. All the patients were reviewed by an independent clinician pre-operatively and post operatively using the assessment tools of Oxford Shoulder Scores (OSS), SF12 and VAS at 6 weeks, followed by 3, 6, 12 months and annually after. We performed a total of 32 IBA procedures. At the latest follow-up we identified that 24 patients have completed 2 years post procedure. Of these patients 1 deceased after 6 months, 3 were lost to follow up one each at 6, 12 and 24 months. Three were revised to reverse TSA. The OSS reflects that the positive difference of 10 in the average scores (24 pre-operative versus 34 at 2 years) noted at one year follow up were maintained at 2 years. Similar observations made analysing at 12 months and 2 years scores for the VAS pain scores of 3 at 2 years compared to pre-operative score of 6 and so were improvements in both physical & mental components of SF12. Our study observes that the IBA provides a sustainable pain relief and functional improvements over 2 years and may be a suitable alternative in physiologically compromised patients with irreparable RCT.

This study aims to investigate the mechanical properties of a rotator cuff tear repaired with a polypropylene interposition graft in an ovine infraspinatus ex-vivo model. Twenty fresh shoulders from skeletally mature sheep were used in this study. A tear size of 20 mm from the tendon joint was created in the infraspinatus tendon to simulate a large tear in fifteen specimens. This was repaired with a polypropylene mesh used as an interposition graft between the ends of the tendon. Eight specimens were secured with mattress stitches while seven were secured to the remnant tendon on the greater tuberosity side by continuous stitching. Remaining five specimens with an intact tendon served as a control group. All specimens underwent cyclic loading with a universal testing machine to determine the ultimate failure load and gap distance. Gap distance increased with progressive cyclic loading through 3000 cycles for all repaired specimens. Mean gap distance after 3000 cycles for both continuous and mattress groups are 1.7 mm and 4.2 mm respectively (P = .001). Significantly higher mean ultimate failure load was also observed with 549.2 N in the continuous group, 426.6 N in the mattress group and 370 N in the intact group. The use of a polypropylene mesh as an interposition graft for large
Rotator cuff tears are common, with failure rates of up to 94% for large and massive tears. 1. For such tears, reattachment of the musculotendinous unit back to bone is problematic, and any possible tendon-bone repair heals through scar tissue rather than the specially adapted native enthesis. We aim to develop and characterise a novel soft-hard tissue connector device, specific to repairing/bridging the tendon-bone injury in significant rotator cuff tears, employing decellularised animal bone partially demineralised at one end for soft tissue continuation. Optimisation samples of 15×10×5mm. 3. , trialled as separate cancellous and cortical bone samples, were cut from porcine femoral condyles and shafts, respectively. Samples underwent 1-week progressive stepwise decellularisation and a partial demineralisation process of half wax embedding and acid bathing. Characterisations were performed histologically for the presence/absence of cellular staining in both peripheral and central tissue areas (n=3 for each cortical/cancellous, test/PBS control and peripheral/central group), and with BioDent reference point indentation (RPI) for pre- and post-processing mechanical properties. Histology revealed absent cellular staining in peripheral and central cancellous samples, whilst reduced in cortical samples compared to controls. Cancellous samples decreased in wet mass after decellularisation by 45.3% (p<0.001). RPI measurements associated with toughness (total indentation depth, indentation depth increase) and elasticity (1st cycle unloading slope) showed no consistent changes after decellularisation. X-rays confirmed half wax embedding provided predictable control of the mineralised-demineralised interface position. Initial optimisation trials show proof-of-concept of a soft-hard hybrid scaffold as an immune compatible xenograft for
Purpose. Chronic massive rotator cuff tears are challenging to repair completely because of the development of tendon retraction with inelasticity, muscle atrophy and fatty infiltration.
