Aims: Parsonage Turner Syndrome (PTS) is a peripheral neuropathy manifesting as sudden onset pain, muscle weakness, and atrophy. This review aims to analyse long-term outcomes reported in adult patients with PTS, and establish an optimised management approach.
Methods: A comprehensive literature search was performed using MEDLINE, PubMed, and the Cochrane Library. Articles that met the eligibility criteria were included. Analysis on time to presentation, presentation, interventions and long-term functional outcomes was conducted. All relevant information was collected by two independent reviewers.
Results: Twenty-five studies, comprising 950 PTS patients, were identified. Patients averaged 43.8 years in age, with a F:M ratio of 0.6:1, and presented symptoms spanning 1-24 months prior to seeking medical attention. Management details were elucidated for 402 patients (42 %), with 87 % managed conservatively. Among conservatively managed patients, over 50 % exhibited no improvement. 62/402 (15 %) necessitated surgical interventions, including neurolysis, decompression, nerve transfers, and diaphragmatic plication. 25/31 (80.6 %) neurolysis cases demonstrated full functional recovery, including pain resolution and full muscle strength, between 1 day and 13 months (average 2.9 months). 2 nerve transfer cases achieved full forward flexion at 2.5 months. Overall, long-term outcomes of PTS, reported at 5-25 months, revealed residual neuropathic pain in 60 % and incomplete motor function return in 70 % of patients.
Conclusions: PTS recognition and referral challenges persist, impeding timely management. While surgical interventions are advocated after three months for incomplete recovery, long-term surgical outcomes are inadequately reported. An optimal surgical strategy for stagnant nerve recovery needs to be devised for this challenging cohort of patients.
