Primary Outcomes (2)
Significantly different proteomics and transcriptomes between Chronic Postsurgical Pain and pain-free subjects
Differences in the proteins in the fluid around the lumbar, between Chronic Postsurgical Pain and Pain-free subjects.,will be quantified using Mass spectrometry,for: neural cell adhesion molecule L1, complement C4-A, lysozyme C, receptor-type tyrosine-protein phosphatase zeta, apolipoprotein D, alpha-1-antichymotrypsin, granulins, calcium/calmodulin-dependent protein kinase type II subunit alpha, mast/stem cell growth factor receptor Kit, prolow-density lipoprotein receptor-related protein 1 and so on. These proteins may identify the disease and define its mechanism.
Up to 3 months after fixation
Inflammatory cytokines in Chronic Postsurgical Pain patients
Biomarkers from CSF will be quantified using Meso Scale Discovery multiplex kit (K15210D), for: CRP, Eotaxin, Eotaxin-3, FGF (basic), ICAM-1, IFN-γ, IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12/IL-23p40, IL-13, IL-15, IL-16, IL-17A, IP-10, MCP-1, MCP-4, MDC, MIP-1α, MIP-1β, PlGF, SAA, TARC, Tie-2, TNF-α, TNF-β, VCAM-1, VEGF-A, VEGF-C, VEGF-D, VEGFR-1/Flt-1. The levels of these biomarkers will be compared between the group between CPSP and pain-free subjects.
Up to 3 months after fixation surgery
Study Arms (2)
Pain-free control subjects
According to the 11th Revision of International Classification of Diseases (ICD-11) of International Association for the Study of Pain(IASP) in 2019, diagnose whether patients have CPSP . Patients with no postoperative chronic pain after open reduction and internal fixation of lower limb fractures.
Patients with chronic postsurgical pain
According to the 11th Revision of International Classification of Diseases (ICD-11) of International Association for the Study of Pain(IASP) in 2019, diagnose whether patients have CPSP . Patients with postsurgical chronic pain after open reduction and internal fixation of lower limb fractures.
Eligibility Criteria
Patients who had undergone open reduction and internal fixation of the lower limbs and planned to take out the internal fixation were interviewed before surgery to collect the basic data ( gender, age, BMI, etc. ) and previous surgical information. Selecting the patients with the chronic postoperative pain,for one-to-one case matching.All patients and control subjects were without any analgesic medicatio during the 24hours before the investigation,and were not using any daily mediciation.Routine blood and urine assessments were within the normal range.
You may qualify if:
- ASA physical status 1 to 3 (males and females)
- Undergone open reduction and internal fixation of the lower limbs and plan to take out the internal fixation under spinal anesthesia
You may not qualify if:
- Absence of written consent
- Contraindication to regional anaesthesia
- Known dementia at time of operation
- History or opioid abuse
- Unexpected conversion of general anesthesia or surgery is not carried out
