Registry of Avive® Soft Tissue Membrane Utilization in Selected Applications of Acute Trauma of the Upper Extremity

A registry study to evaluate the role of Avive® Soft Tissue Membrane in the management of nerve injury associated with acute trauma in the upper extremity.

This is a multicenter outcomes registry study of Avive® Soft Tissue Membrane in the management of nerve injuries associated with selected upper extremity acute trauma. The study will evaluate clinical condition, economic impact, and functional outcomes.

Eligibility Criteria:
Inclusion Criteria:

1. Subjects 5 to 70 years of age, inclusive;
2. Sign and date an IRB/IEC -approved written informed consent form (ICF) prior to initiation of any study activities;

   1. Group One only: Subject enrollment (ICF completion) must be completed within 2 weeks (7-14 days) post-operatively of the targeted surgical procedure;
   2. Group Two Retrospective subjects only: Sign and date an IRB/IEC - approved written informed consent form (ICF) prior to initiation of any study activities if required per the governing IRB;
3. Group One only: Subjects who have undergone placement of Avive® Soft Tissue Membrane over at least one exposed nerve, circumferentially, or as an overlay between the exposed nerve(s) and the surrounding wound bed during surgical intervention following one or more of the following targeted acute upper extremity traumas (selected injuries): Spaghetti Wrist, Distal Radius Fractures, Medial Epicondyle Fractures, Flexor Tenolysis at Wrist, and/or Ballistic Injuries in the Forearm and/or Hand. This surgical intervention must have been completed within 60 days from the date of injury;
4. Group Two only: Subjects who have undergone surgical intervention for one or more of the following targeted acute upper extremity traumas (selected injuries): Spaghetti Wrist, Distal Radius Fractures, Medial Epicondyle Fractures, Flexor Tenolysis at Wrist, and Ballistic Injuries in the Forearm and/or Hand in the past 5 years without placement of a surgical implant over the exposed nerve, circumferentially, or as an overlay between the exposed nerve(s) and the surrounding wound bed during surgical intervention. This surgical intervention must have been completed within 60 days from the date of injury;
5. Group Two only: Subjects must have at least 1 qualifying post-operative injury assessment;
6. Subject is willing and able to comply with all aspects of the treatment and evaluation schedule.

Exclusion Criteria:

1. Subjects with complete transection of all nerves affected by one or more of the following selected injuries: Spaghetti Wrist, Distal Radius Fractures, Medial Epicondyle Fractures, Flexor Tenolysis at Wrist, and Ballistic Injuries in the Forearm and/or Hand. Subjects with nerve transection(s) must also have ≥1 affected nerve intact (non-transected) for treatment with Avive® Soft Tissue Membrane (Group One) or without treatment with a surgical implant (Group Two);
2. Subjects with Type 1 Diabetes Mellitus or Type 2 Diabetes Mellitus requiring regular insulin therapy;
3. Subjects who are currently receiving, or have previously received, treatment with chemotherapy, radiation therapy, or other known treatment which affects the growth of the neural and/or vascular system;
4. Subjects that are currently taking, or have previously used, a medication that is known to cause peripheral neuropathy;
5. Subjects with a history of chronic ischemic condition of the upper extremity; and
6. Any subject who, at the discretion of the Investigator, is not suitable for inclusion in the study.
