Aim of Investigation: Iatrogenic nerve injury has been proposed as the main factor responsable for long term-postsurgical pain. The prevalence of chronic neuropathic pain after a known somatosensory lesion in the upper extremity nerves followed by suture surgery was determined.
Methods:The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale questionnaires were sent out in January 2016 to 1078 patients who underwent nerve repairs operations after traumatic or surgical nerve injuries of the upper limbs between 2006 to 2014 at the Hand Surgery Clinic.
Results: Three hundred eighty-two patients returned the questionnaire (response rate 35%). Post trauma or post-surgical pain was present in 186 patients (48 %) from those 382 patients who responded to the questionnaire. A total of 87 patients (47 %) of these 186 patients developed chronic pain after the operation. The most common symptom experienced by the patients was the enhanced sensitivity to cold in 69 % of the patients that led to pain and discomfort at temperatures that normally were perceived as being innocuously cool. Other symptoms were diminished sensitivity to stimulation in 55% of the patients and allodynia to light pressure, cold presented in 50% of the patients. The majority of the patients with pain resulting from traumatic or surgical nerve injury (77% of the patients) had no medication for pain, despite the presence of pain more than 50 VAS.
Conclusions: Persistent neuropathic pain occured in 48% of the patients following nerve suture surgery. Cold intolerance has a high prevalence both in the group of patients with pain and in the group without pain.
