PMT, pectoralis minor tenotomy; SCD, supraclavicular decompression; QuickDASH, 11-item version of the Disabilities of the Arm, Shoulder, and Hand survey; SC, supraclavicular; NTOS, neurogenic thoracic outlet syndrome.
Patients undergoing primary surgical treatment for NTOS from January 1, 2020 to July 1, 2023. Data shown indicate the mean ± SE or the number and proportion (%) of patients in the study population.
b
P < .0001, preoperative versus follow-up, paired student t-test.
c
Comparison between SCD + PMT versus isolated PMT groups, unpaired student t-test (continuous variables) or Fisher’s exact test (categorical variables); NS, P > .05.
