Abstract
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.
