What is a balloon spacer?
The InSpace™ balloon spacer is used to reduce friction between the humeral head and the undersurface of the acromion. 27. By depressing the humeral head inferiorly and restoring the kinematics of an intact shoulder, it aims to improve pain and function.
What is a shoulder balloon arthroplasty?
Balloon arthroplasty is a promising procedure that has a place in the range of options in caring for nonrepairable rotator cuff tears. It is a new procedure and long-term studies, beyond three years, have not been performed. The device is also pricey, which may impact its use in certain centers.
What is the InSpace balloon made of?
The Ortho-Space InSpace TM system is a biodegradable balloon-shaped spacer made of a copolymer Poly (l-lactide-co-ε-caprolactone) which biodegrades over 12 months, during which stage the force coupling should return and allow for long-term improvement in the glenohumeral joint movement.
What is the superior capsule of the shoulder?
The superior capsule is the upper part of the capsular lining of your shoulder joint. It has been shown to have a useful role in helping centre the humeral head on the glenoid socket and thereby assisting with elevation of your arm. This is a role normally played by your supraspinatus rotator cuff tendon.
What is in the subacromial space?
The subacromial space refers to the space above the shoulder’s glenohumeral joint (ball-and-socket joint) and below the acromion, the top-most bone of the shoulder. Soft tissues, such as the bicep tendon, rotator cuff, and bursa are located in the subacromial space.
How is shoulder replacement done?
In a typical shoulder replacement, a plastic lining is attached to the socket to allow smooth movement. The surgeon removes the top of the arm bone and inserts a metal stem with a ball on the end. However, if the rotator cuff is severely damaged, the joint may not be stable or work properly.
How long is the recovery from a superior capsular reconstruction?
Typically, the average recovery time for superior capsular reconstruction can be 8-12 months.
What is subacromial bursa?
In the shoulder, the subacromial bursae cushion the area between the rotator cuff tendons and the acromion (the highest point of the shoulder blade or scapula). Bursae allow the tendons and bones to glide without friction when you move and lift your arms.
Which is worse knee or shoulder replacement?
Summary: Contrary to widespread belief, total surgical replacement of arthritic shoulder joints carries no greater risk of complications than replacement of other major joints, a Johns Hopkins study suggests. Total shoulder replacements are as safe as swapping out hips and knees, according to Hopkins researchers.
Is there an implantable biodegradable subacromial balloon spacer?
In recent years, yet another option, an implantable biodegradable subacromial balloon spacer has become available with promising early results. Recent findings: Biomechanical studies have demonstrated that the balloon spacer effectively restores the normal humeral head position and glenohumeral joint mechanics.
Is the balloon subacromial spacer effective for rotator cuff tears?
Certain studies have shown a benefit when the procedure is done in isolation as well as in combination with other arthroscopic procedures, such as partial rotator cuff repair. The balloon subacromial spacer is a promising new device that can be used in the treatment of patients with massive, irreparable rotator cuff tears.
What is a subacromial bursa?
A bursa is a fluid-filled sac found at several locations in the human body. It serves to lubricate joints and body surfaces exposed to higher degrees of wear and friction. The subacromial space in the shoulder is such a location.
What are the possible complications of the subacromial balloon?
We have observed a few complications with the subacromial balloon. We had one case of migration, which was resolved by removal and replacement of the spacer in a different orientation. No other device-related complications have been observed, and the complication profile is otherwise comparable to that of an arthroscopic debridement.
