The InSpace balloon spacer
What is the InSpace balloon spacer?
The InSpace subacromial balloon spacer is an implant intended for the treatment of patients with MRCTs for patients 65 years of age and older whose clinical conditions would benefit from treatment with a shorter surgical time compared to other surgical treatment options. It is an inflatable device made of a biodegradable material that comes in three sizes (Small, Medium and Large) to fit different shoulder anatomies.
How does the InSpace balloon work?
The InSpace implant is inserted into the space under the outer edge of your shoulder (subacromial space) during a minimally invasive arthroscopic procedure. This helps restore the space between your upper arm bone (humerus bone) and the outer edge of your shoulder (acromion) and also temporarily reduces rubbing between these bones. This helps to relieve pain associated with tendon tears and enables the bones in your shoulder to glide easily next to each other.
Once implanted into your shoulder, the InSpace implant biodegrades over time and has been shown to be completely resorbed after approximately one year.
The InSpace implant provides a simple and minimally invasive alternative arthroscopic surgical treatment for massive, irreparable rotator cuff tears with long-term safety and effectiveness results similar to an arthroscopic surgical Partial Repair treatment, which is a commonly performed procedure.1
Please note that while many patients may experience benefits from treatment with the InSpace implant, good results after InSpace implant surgery are not guaranteed. Risks of using the InSpace implant include irritation at the surgery site, local infection, inflammation, or tissue damage, worsening of an existing infection or movement of the implant out of its intended location. Your surgical procedure may also cause complications or adverse events, which could require treatment such as medicine or additional surgery. Please refer to "Important Information" below for further details on risks.
To assess the safety and effectiveness of the InSpace implant, a clinical study was performed. The results of the InSpace implant study can be found in the Resources section called "Clinical data, stats and figures about the use of InSpace for arthroscopic treatment of massive, irreparable rotator cuff tears."
Discuss treatment options with your surgeon to determine if treatment with the InSpace subacromial balloon spacer is right for you.

IMPORTANT INFORMATION ABOUT INSPACE
The InSpace Implant is indicated for the treatment of patients with massive, irreparable full-thickness torn rotator cuff tendons due to trauma or degradation with mild to moderate gleno-humeral osteoarthritis in patients greater than or equal to 65 years of age whose clinical conditions would benefit from treatment with a shorter surgical time compared to partial rotator cuff repair.
The InSpace Implant is not appropriate for patients with certain types of infections, known or suspected allegories to the implant and/or instrument materials, or children.
The following information provided is based on data collected in the US Pivotal Clinical Study. There is evidence of increased risk of total adverse events of the affected shoulder compared to a partial rotator cuff repair, which were reported to be mostly mild to moderate in severity. Please note that complications reported by InSpace and Partial Repair patients were reviewed by a group of experts in shoulder surgery, and it was determined that none were related to the treatment devices (i.e., the InSpace Implant or devices used for Partial Repair). There is evidence of increased adverse events associated with a serious risk of the index shoulder which includes both medical and surgical treatments. The InSpace Implant is not fixed in place and may change position in the shoulder space. Movement out of the subacromial space and/or deflation of the InSpace Implant was observed in magnetic resonance imaging (MRI) 6 weeks post-operatively in up to half of patients. In these cases, it should be noted that no re-operations were required to remove the InSpace Implant.
The risks and benefits of the InSpace Implant in patients with the following conditions should be carefully considered: severe arthritis in the shoulder or full thickness cartilage loss, deltoid muscle defect or deltoid muscle paralysis, evidence that the shoulder is very unstable, missing or non-intact ligaments in the shoulder, known loss of sensation, major medical conditions such as blood clotting disorders, conditions that suppress the immune system or any other conditions that may compromise healing, safety and effectiveness of InSpace Implant use in patients below age sixty-five (65) has not been established, and safety and effectiveness of InSpace Implant use in pregnant or nursing mothers has not been evaluated.
If a reaction occurs, it will require follow-up with your surgeon. Some examples are as follows: irritation at the site where a cut was made during surgery, local infection, inflammation, and tissue damage where the InSpace Implant was implanted, or worsening of an existing infection. Additionally, movement of the implant out of its intended location may lead to worsening of your shoulder pain, discomfort, and/or stiffness which may require a re-operation, narcotic medications, non-narcotic pain medications, or post-operative shoulder injections.
As with any surgery, your surgical procedure may cause complications or adverse events. As with any shoulder surgery involving anesthesia there are potential risks and complications, including dizziness, fainting, difficulty breathing, wound infection, wound drainage, swelling, local pain, bleeding, bruising, surgical wound opening, nerve pain or injury which could result in partial or complete loss of movement in your affected arm, tendon injury, loss of sensation in your skin and muscle around your surgical site, inflammation of the tissues that surround your rotator cuff joint, a frozen rotator cuff (inability to freely move the shoulder joint) and delayed wound healing. There is a risk that a deep vein clot will form (thrombosis) and travel to the lung (pulmonary embolism), which could lead to stroke, heart damage or death. Any of the aforementioned complications/risks could require treatment such as medicine or additional surgery that may involve replacing or removing your InSpace Implant dependent on timeframe as the implant is biodegradable.
The information presented is for educational purposes only. Speak to your doctor to decide if you are interested in learning more about the InSpace Implant. Individual results vary and not all patients will receive the same postoperative activity level. It is important to follow your surgeon’s advice regarding after surgery care (for example, physical therapy) as well as which immediate activities you may or may not perform after receiving the InSpace Implant. Not following this advice may cause complications with the InSpace Implant. Some complications may require you to have additional surgery. Ask your doctor if the InSpace Implant is right for you.
