Patient outcomes and satisfaction are an ever-increasing priority in surgical specialties. Cryotherapy has been utilized following spine surgery as an adjunct therapy to reduce postoperative inflammation and improve patient outcomes. However, limited studies have investigated the effect of cryotherapy on postoperative pain and narcotics use. Fountas et al. performed a randomized controlled trial to assess the impact of postoperative cryotherapy following single-level lumbar microdiscectomy. The authors reported patients receiving cryotherapy required significantly less pain medication (0.058 mg/kg/hr versus 0.067 mg/kg/hr, p<0.001) and had shorter hospital stays (1.71 days versus 2.65 days, p<0.001) as compared to the control group. In another randomized trial of single-level lumbar discectomy patients, Murata et al. demonstrated cryotherapy to have no significant effect on VAS inpatient pain scores or postoperative blood loss.
The purpose of this study is to determine if postoperative cryotherapy with a cold-therapy system reduces postoperative pain and narcotic consumption following single and multi-level spinal fusion.
The investigators hypothesize that patients undergoing lumbar spinal fusion who receive postoperative cryotherapy treatment with a cold-therapy system will have reduced inpatient pain scores and require less narcotics as compared to patients that receive standard care (ice pack).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cold-therapy system | Experimental | Patients will receive a cold-therapy system postoperatively (Polar Care Kodiak, Breg®) and will use the system during inpatient stay and during the first 14 days post-discharge. |
|
| Standard care (ice-pack) | No Intervention | Patients will use disposable ice-pack as per standard of care |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Cold-Therapy System | Device | After surgery, participants assigned to this group will receive the cold-therapy system to use at the hospital and during the first 2 weeks following discharge. |
| Measure | Description | Time Frame |
|---|---|---|
| Postoperative Pain | Average daily Visual Analog Scale (VAS) survey, which measures pain, for the duration of hospital stay and postoperative VAS scores will be recorded for 2 years postoperatively. This information will be collected through a survey that will be administered upon patient discharge. Patients will be asked to return the completed survey to the research team. VAS scale ranges from 0 - 100 mm, with 100 representing maximum pain and 0 representing no pain. | 2 year postoperative |
| Narcotics Consumption | Total, daily, and hourly narcotics consumption during the hospitalization. Narcotic consumption will be recorded for 2 weeks following discharge. Patients will be asked to report the number of narcotic pills taken each day. This information will be collected through a survey that will be administered upon patient discharge. Patients will be asked to return the completed survey to the research team. | 2 weeks postoperative |
| Measure | Description | Time Frame |
|---|---|---|
| Bony fusion | Postoperative radiographs and CT scan will be used to assess fusion. | 2 year postoperative |
| Disability | Postoperative Oswestry Disability Index (ODI) survey scores will be compared to preoperative values. ODI measures disability for lumbar patients. The scale ranges from 0% to 100%. 0-20% represents minimal disability, 21-40% represents moderate disability, 41-60% represents severe disability, 61%-80% represents a crippled state, and 81-100% represents a bed-bound patient. |

| 2 year postoperative |
| Physical Function: Patient-Reported Outcomes Measurement Information System (PROMIS) | Postoperative PROMIS scores will be compared to preoperative values. PROMIS evaluates physical function through a series of questions covering level of difficulty with normal daily activities. A score of 5 represents "without any difficulty" and a score of 1 represents "unable to do". | 2 year postoperative |
| General Health Status: Short-Form (SF-12) | Postoperative SF-12 scores will be compared to preoperative values. SF-12 evaluates the general health status of the patient. A minimum score of 0 represents the lowest level of health, while a maximum score of 100 represents the highest level of health. | 2 year postoperative |
| Length of Stay | The number of hours of hospitalization from entering the recovery room (time zero) until patient meets discharge criteria. | Up to 2 weeks |
| Disposition on discharge | This outcome evaluates where the patient will return to after their inpatient stay. This could include, but is not limited to, their home, a rehabilitation facility, or a skilled nursing facility. | Up to 2 weeks |
