Clavicle Splint for Pain Reduction After Posterior Cervicothoracic Surgery

Overview

The purpose of the study is to see whether a clavicle splint can decrease the pain after posterior cervicothoracic surgery. The term "cervicle splint" conveys that the investigators do not deal with clavicle fractures here but use the splint he stabilize the posterior cervical area. The investigators want to demonstrate this in a prospective randomized manner.

In this prospectively controlled randomized study 30 patients who had undergone posterior cervical spine surgery were randomized into two groups who either wore or did not wear a clavicle brace to retract the shoulders. Patients in the brace group began wearing the brace on postoperative day 4, and continuously wore it throughout the 30-day study period. Outcome was measured as daily levels of self-reported pain and number of pain pills taken during the 30-day postoperative period. . After hypothesizing a mean pain reduction through the brace on the visual analog scale (VAS) for pain from 5 to 3 with a standard deviation of 1, we calculated that at a power level of 99% and an alpha error of 5%, and given that the VAS numbers were normally distributed, we needed 22 patients to enroll into the study. We increased this number to 30 to account for early and late dropouts. The study was performed at a single institution with patients from 2 different spine surgeons. Patients were randomized prior to or the day after the procedure to either wear or not wear the clavicle brace. Randomization was done through closed envelopes that the patients drew. Dissection was performed by the two fellows at our institution and depended solely on the number of fused levels and whether or not a tumor had to be removed. Closure was also performed by the two spine fellows after instruction by the senior author. Cervical alignment was reviewed using the C2-C7 angle according to Cobb's method on lateral images. The cervico-thoracic angles were calculated by the addition of the cervical spine angle and the remaining angles of thoracic spine until T3 according to Cobb's method. The brace was provided by the hospital. Patients were instructed how to properly wear the brace by the first author, the senior author, or the hospital Rehabilitation Orthotics specialist. To complete the study, patients wore the brace for at least 30 days. (Patients of J.P. continued to wear the brace for 3 months outside of the study period.). All patients wore hard cervical collars until the end of the study period. Patients self-recorded their average level of pain on a scale from 1 to 10 for each post-surgery day beginning on postoperative day 2. They also recorded the number of pain pills they took each day. On the same sheet used to record medication usage, patients were instructed to record each day whether they were able to wear the brace or if they experienced problems. At their 1 month postoperative visit the incision was inspected and palpated by the first or senior author for the presence of fascial dehiscence and its occurrence was recorded. Every patient routinely received narcotic and non-narcotic pain medication on an as-needed basis in the hospital. No nonsteroidal anti-inflammatory drugs, such as ibuprofen or ketorolac, were given. If, on a particular postoperative day, patients were still on an intravenous narcotic patient-controlled anesthesia (PCA), that day's data were not recorded for the study.
