Self-assessed outcomes following double fascicular nerve transfer for elbow flexion.

BACKGROUND

Double fascicular nerve transfer (DFT) is often performed to re-animate the elbow flexors. Studies of motor recovery following this surgery have exclusively reported on the objective outcome of muscle power. Questionnaire studies allow researchers and clinicians to learn from patients and better direct care towards their needs. To date, no research has focused on self-assessed recovery following DFT for elbow flexion.

METHODS

This observational cross-sectional study aimed to give an account of patient-assessed outcomes following DFT. The bespoke questionnaire included: (a) self-reported strength and (b) the Stanmore percentage of normal elbow assessment.

RESULTS

Sixty-two patients participated in the study. Participants were grouped according to time post-surgery. Statistical analysis confirmed that data were comparable between groups (=0.10).

SELF-ASSESSED STRENGTH: Median scores were 0.5 kg <2 years post-surgery, 3 kg at 2 to 5 years, 2 kg at 5 to 8 years and 1.3 kg in the >8 years group.

STANMORE PERCENTAGE OF NORMAL ELBOW ASSESSMENT

Mean scores (%) were 35 (SD ± 25) <2 years, 56 (SD ± 31) at 2 to 5 years, 44 (SD ± 25) at 5 to 8 years and 46 (SD ± 29) >8 years groups.

CONCLUSIONS

This is the first study of self-assessed recovery following DFT. Scores peaked around 4 years post-operation. Future research should focus on the long-term self-reported outcome of nerve transfer surgery.
