Allograft Adipose Matrix (AAM) in Subcutaneous Dorsal Wrist

This is a 16 week pilot study to assess short term outcomes of an injectable allograft adipose matrix (AAM) in the subcutaneous space in the dorsum of the wrist. A total of 30 patients will be enrolled at 2 sites and will be followed for sixteen weeks. Volume retention and local skin changes will be observed and documented prior to and following injection at week 0 and at follow up visits at 2, 10 and 16 weeks. Evaluations will be done via photographic analysis at week 0,2,10 and 16 weeks and half of the patients will undergo magnetic resonance imaging at week zero and at week 16. The dominant wrist will serve as a control and will receive no injection. Analysis includes volume retention, tissue analysis, local skin changes and adverse events, if any.
