Upper Extremity Surgery in Cervical Spinal Cord Injury: A Prospective Comparative Mixed-Methods Study.

Abstract

Cervical spinal cord injury (SCI) has a devastating effect on health and independence. Restoring upper extremity function is a top priority and can be accomplished by tendon transfer (TT) and nerve transfer (NT) surgery. The purpose of this prospective comparative study was to assess long-term changes in upper extremity function between surgical (TT or NT) and nonsurgical groups through a comprehensive mixed-methods approach. This multicenter cohort study compared data among 3 groups: those undergoing no surgery, TT surgery, or NT surgery. Quantitative data from the Spinal Cord Independence Measure (SCIM) and 36-item Short Form Health Survey were collected at baseline and long-term follow-up (6 to 24 months). Qualitative semistructured interview data were also obtained from these participants and their identified caregivers at baseline, early follow-up (1 month), and long-term follow-up (6 to 24 months). Thirty-one participants had quantitative data across all time points: no surgery ( n = 14), TT ( n = 7), and NT ( n = 10). SCIM scores improved in TT and NT groups compared with the no-surgery group ( P < 0.05). The 36-Item Short Form Health Survey scores did not differ among groups. Qualitative data analysis ( n = 168 interviews) corroborated SCIM findings: surgical participants and their caregivers reported improvement in transfers and ability to perform activities of daily living, including grooming and self-catheterization. Improved use of electronics and ability to operate a motor vehicle were also reported. Postoperative therapy was identified as a critical component of achieving gains. TT and NT surgery lead to quantitative and qualitative functional gains when compared to no surgery. This comparative information should be used to help surgeons discuss treatment options.
