Abstract
OBJECTIVE The objective of this prospective randomized study was to compare ulnar nerve decompression and anterior subfascial transposition with versus without supercharged end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer for advanced cubital tunnel syndrome, to describe performing the nerve transfer through a small incision, and to investigate predictive factors for poor recovery following the procedure. METHODS Between January 2013 and October 2016, 93 patients were randomly allocated to a study group (n = 45) and a control group (n = 48). Patients in the study group were treated with supercharged motor nerve transfer via a 5-cm incision following decompression and anterior subfascial transposition. Patients in the control group were treated with decompression and anterior subfascial transposition alone. Postoperative pinch strength and compound muscle action potential amplitude (CMAPa) were assessed. Function of the limb was assessed based on the Gabel/Amadio scale. Between-group data were compared, and significance was set at p < 0.05. Potential risk factors were collected from demographic data and disease severity indicators. RESULTS At the final follow-up at 2 years, the results of the study group were superior to those of the control group with regard to postoperative pinch strength (75.13% ± 7.65% vs 62.11% ± 6.97%, p < 0.05); CMAPa of the first dorsal interossei (17.17 ± 5.84 mV vs 12.20 ± 4.09 mV, p < 0.01); CMAPa of abductor digiti minimi (11.57 ± 4.04 mV vs 8.43 ± 6.11 mV, p < 0.01); and excellent to good results (0.67 for the study group vs 0.35 for the control group, p < 0.05). Multivariate analysis showed that the advanced age (OR 2.98, 95% CI 2.25-4.10; p = 0.003) in the study group was related to unsatisfactory outcome in the patients. CONCLUSIONS In the treatment of advanced cubital tunnel syndrome, additional supercharged end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer may produce a better function of the hand. The authors also found that cases in the elderly were related to unsatisfactory postoperative results for these patients and that they could be informed of the possibility of worsening surgery results.

[PMID: 28197789 DOI: 10.1007/s00701-017-3113-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Accepted: 02/03/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND Surgical outcomes for cubital tunnel syndrome have been reported to be satisfactory, but could be compromised by advanced age and severe nerve compression. We aim to evaluate the prognosis of severe cubital tunnel syndrome in patients aged >70 years. METHODS This retrospective study included 25 patients (26 extremities, all McGowan grade III, age >70 years); 21 underwent subcutaneous transposition and 5 in situ decompression. Postoperative follow-up lasted >2 years. Demographic data, clinical symptoms, physical examination findings, and the Disabilities of the Shoulder, Arm, and Hand Questionnaire were evaluated preoperatively and at final follow-up. Pain and weakness were evaluated using the visual analog scale and overall functional recovery using the modified Bishop's Score and McGowan Grade. RESULTS Significant improvements were seen in both sensory and motor function. VAS pain and weakness, 2-PD, key-pinch strength, grip strength, first dorsal interosseous muscle strength, the Wartenberg sign, and claw hand all improved significantly. DASH scores improved from an average of 45.2 points preoperatively to 15.9 points postoperatively. According to the modified Bishop scoring system, 10 extremities were graded excellent; 12, good; 2, fair; and 2, poor. Improvement of at least one McGowan Grade was seen in 18 cases, but only 2 extremities recovered to normal. CONCLUSION For patients aged >70 years with severe cubital tunnel syndrome, surgical treatment is effective, but complete recovery is unlikely, and the recovery process is long.
