Summary

Rotator cuff disease (i.e., rotator cuff tendinopathy or tear) is a common cause of shoulder pain in persons with chronic spinal cord injury (SCI). It usually resolves with non-operative treatments such as pharmacological agents and physical therapy; however, when this fails, rotator cuff surgery may be the only option. Corticosteroid injections are another alternative to provide temporary relief, but can over time accelerate degeneration of the tendon and lead to further damage. Autologous adipose tissue injection has recently emerged as a promising new treatment for joint pain and soft tissue injury. Adipose can be used to provide cushioning and filling of structural defects and has been shown to have an abundance of bioactive elements and regenerative perivascular cells (pericytes). The purpose of this study is to explore the efficacy of autologous, micro-fragmented adipose tissue (Lipogems®) injection under ultrasound guidance for chronic shoulder pain in persons with SCI compared with the standard-of-care, corticosteroid injection.

Detailed description

This is randomized controlled trial to determine the efficacy of autologous, micro-fragmented adipose tissue (MFAT) injection under ultrasound guidance for chronic, nonresponsive shoulder pain due to rotator cuff disease (i.e., rotator cuff tendinopathy) in persons with spinal cord injury (SCI). The control for this study, to which MFAT will be compared, is corticosteroid injection into the subacromial space. Twenty-four (24) persons with SCI who have chronic shoulder pain for longer than 6 months in spite of completing conservative treatment and who are diagnosed with rotator cuff disease on examination will be recruited. MFAT Group: Micro-fragmented adipose tissue will be obtained by using a minimal manipulation technique in a closed system (Lipogems®), without the addition of enzymes or any additives. The final product will consist of micronized fat tissue yielding fat clusters with preserved vascular stroma of about 500 microns with intact stromal vascular niches and harboring regenerative cellular elements. Approximately 6 mL of micro-fragmented adipose will be injected into the tendon with a 22-gauge needle under continuous ultrasound guidance. No other biological or pharmacological agents will be used in combination with the micro-fragmented adipose. Corticosteroid Group: In the corticosteroid group, participants will receive a corticosteroid injection (BMS, Kenacort-A 40 mg \[triamcinolone acetonide\]) into the subacromial space under direct ultrasound guidance by means of a 5-mL syringe with a 22-guage needle. Both Groups: After 24 hours, participants will be given a standardized stretching protocol to follow for 4 weeks followed by a formal strengthening program. Participants will be followed for adverse events and changes in shoulder pain intensity on an 11-point numerical rating scale (NRS; 0-10, with anchors "no pain" and "pain as bad as you can imagine"); the Wheelchair User's Shoulder Pain Index (WUSPI; 15-item disease-specific functional measure of shoulder pain in persons with SCI); the PROMIS Physical Functioning short form; the Brief Pain Inventory interference items (BPI-I7; a subscale of 7 items measuring interference with general activity, sleep, mood, relationships, etc.); and a 5-point subject global impression of change (SGIC) scale. Subjects will be examined at 1 month, 2 months, 3 months, and 6 months after the treatment. In addition to subjective outcome measures, quantitative ultrasounds will be conducted at baseline, 1 month, 2 months, 3 months, and 6 months post-treatment.

Interventions

Type	Name	Description
DEVICE	Lipogems	The Lipogems system (Lipogems International SpA, Milan, Italy) is designed to isolate autologous, micro-fragmented adipose tissue without enzymes or other additives. It uses mild mechanical forces to break down adipose tissue that is extracted from the patient into a form that can be injected into the tendon lesion and other degenerated tissues in a sterile and safe manner. The resulting product is rich in pericytes and mesenchymal stromal cells, retained within an intact stromal vascular niche, that is ready for use in clinical applications.
DRUG	Dexamethasone	Triamcinolone Acetonide is a corticosteroid, which is a class of drugs that are commonly prescribed for shoulder pain. They work to reduce pain by limiting inflammation. They are typically injected into the subacromial space with or without ultrasound guidance.
