Background:
Complex regional pain syndrome is a challenging condition includ-
ing a broad spectrum of sensory, autonomic and motor features predominantly
in extremities recovering a trauma. Surgical and non- surgical treatments are
known risk-factors. Few large-scale studies have addressed occurrence of and
factors associated with CRPS following orthopedic treatment.
Purpose / Aim of Study:
The present study aimed to identify factors associ-
ated to post-treatment development of CRPS.
Materials and Methods:
Using the Danish Patient Compensation Association’s
database (DPCA), we identified 647 patients with post-treatment CRPS
(DM89.0), between January 1, 1992 and March 5, 2015. Age, gender, initial
diagnosis, treatment, debut date of CRPS, severity of CRPS and size of com-
pensation were extracted. A multiple logistic regression was performed to as-
sess variables with association to approval of the claim made to DPCA. In the
cases of CRPS in patients with carpal tunnel syndrome we analyzed bilateral
vs. unilateral symptoms and whether neurophysiological changes prior to treat-
ment were seen.
Findings / Results:
The following variables were excessively represented;
woman gender 4:1, primary diagnosis to the upper limb 2½:1 and surgical treat-
ment 3:1. Mean age was 47.5±13.7, no difference between gender. Colles’
fracture (12%) and carpal tunnel syndrome (9%) were the most common di-
agnoses. Conservative treatment was negatively associated with approval of
the claim (OR 0.29). Among CTS patients with unilateral symptoms 71.4% had
normal neurophysiology prior to surgery.
Conclusions:
Female gender, surgical treatment and treatment to the upper
limb were risk factors. Elective surgery accounted for a large amount of patients
with post- treatment CRPS. Among CTS patients with carpal tunnel syndrome,
a normal neurophysiological examination is common.
