Duration of Immobilization After Reverse Total Arthroplasty for Proximal Humerus Fractures
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate compare postoperative range of motion in patients who are given a sling for comfort only and allowed to start early active range of motion compared to patients who are placed in a sling for 4 weeks with passive range of motion only. Once enrolled, the patients will be randomized through computer randomization then placed in paper packets into either the immobilization group or the early range of motion group.

Detailed Description
Reverse shoulder arthroplasty is often used for older patients with displaced proximal humerus fractures in the older patient population. Many surgeons have historically placed patients in a sling for 4-6 weeks after surgery to prevent dislocation or tuberosity displacement. More recently though, surgeons are becoming more lenient with these restrictions as they realize it is very difficult for an elderly patient to be immobilized for 4-6 weeks. There has been one randomized control trial looking at early range of motion versus immobilization for 6 weeks after a regular reverse total shoulder arthroplasty not done for fracture which showed no difference at one year. There have not been any studies to date looking at reverse total shoulder arthroplasty for fracture to see if there is any difference in range of motion at early or later time points and also if there is an increased risk of complications.
Preoperative visit/hospitalization: The patient will be identified as meeting inclusion criteria and the study will be explained to them. Patients will be given a consent form to review with adequate time to review and decide if they wish to participate. If they choose to participate, the patient will sign consent forms witnessed by personnel not associated with the study. Patients will be randomized once consent has been obtained.
The patient will then undergo surgery. Operative data will be collected from their chart including implants used, and intraoperative complications. They will be placed in a sling if they are randomized to the sling group and given instructions on passive range of motion exercises to start postoperative day one. If they are assigned to the early motion group they will be placed in a sling for comfort after surgery but told they can remove it when they feel their pain will allow. They will also be instructed on the same passive range of motion program as the sling group. This is different from the standard of care.
Once enrolled, the patients will be randomized through computer randomization then placed in paper packets into either the immobilization group or the early range of motion group.
They will undergo their reverse total shoulder arthroplasty for fracture as they will even if they do not agree to participate in the study (normal treatment)
The immobilization group will be placed in a shoulder abduction sling immediately after surgery for four weeks. They will be allowed to start gentle passive range of motion with forward flexion to 120 degrees, abduction to 90 degrees, and external rotation to 30 degrees. They will receive a home exercise program and formal physical therapy with these limits.
When they come out of the sling at four weeks they will start active range of motion and active assisted range of motion. They cannot internally rotate until 10 weeks after surgery. No formal strengthening until 3 months after surgery.
The early range of motion group will be given a sling for comfort after their surgery. They will be told they can use their arm as tolerated and can remove the sling when comfortable immediately after surgery. They will be allowed to start passive range of motion, active assisted range of motion, and gentle active range of motion with therapy as tolerated with the exception of no internal rotation. They will also not be allowed to strengthen until 12 weeks after surgery. They will get formal physical therapy and be given a home exercise program as well that will be directed by their physical therapist
Both groups will be evaluated postoperatively at 2 weeks, 6 weeks, 12 weeks, 6 months, 1 year, and two years. At each time point the following will be evaluated.
Visual analog pain score American Shoulder and Elbow Society Scores Range of motion Complications Radiographs will be obtained at these visits
Thereported outcome scores will either be recorded in the office or via email using the surgical outcomes system database that is already approved for use at Cooper via legal for quality outcome measures. The patient will be allowed to determine which method they would prefer and is easier for them.
All of these visits will be the same as patients who choose not to enroll in the study. No additional visits are required for the study. The only differences in treatment will be obtaining the patient outcome scores listed above and the random assignment to one of two treatment groups. The random treatment assignments are as follows; the first group of patients will be placed in a sling for four weeks but with early stretching through physical therapy, and the second group will be allowed to use the sling for comfort only and use their arm as tolerated for motion activities such as dressing and bathing. The second group will also receive physical therapy.
The results of the study will not be shared with the subjects or others unless they ask at the completion of the study at which point final data will be revealed to the subjects that ask.

| Immobilization Group The immobilization group will be placed in a shoulder abduction sling immediately after surgery for four weeks. They will be allowed to start gentle passive range of motion with forward flexion to 120 degrees, abduction to 90 degrees, and external rotation to 30 degrees. They will receive a home exercise program and formal physical therapy with these limits.

| Early ROM The early range of motion group will be given a sling for comfort after their surgery. They will be told they can use their arm as tolerated and can remove the sling when comfortable immediately after surgery. They will be allowed to start passive range of motion, active assisted range of motion, and gentle active range of motion with therapy as tolerated with the exception of no internal rotation. They will also not be allowed to strengthen until 12 weeks after surgery. They will get formal physical therapy and be given a home exercise program as well that will be directed by their physical therapist |

Outcome Measures
Primary Outcome Measures
- Early postoperative range of motion [2 years]
the postoperative range of motion (ROM) will be compared between the 2 groups at 2 weeks, 6 weeks, 12 weeks, 6 months, 1 year, and two years
- Postoperative Pain [2 years]
Patients will rate their pain using the VAS pain scale survey. The visual analog scale (VAS) is a pain rating scale first used by Hayes and Patterson in 1921. Scores are based on self-reported measures of symptoms that are recorded with a single handwritten mark placed at one point along the length of a 10-cm line that represents a continuum between the two ends of the scale-"no pain" on the left end (0 cm) of the scale and the "worst pain" on the right end of the scale (10 cm). This scale will be administered to both groups at 2 weeks, 6 weeks, 12 weeks, 6 months, 1 year, and 2 years. The results of these scores will be compared between the two groups at each time point.
- Shoulder function [2 years]
the postoperative shoulder function assessed by the American Shoulder and Elbow Scale (ASES). This scale includes a section on pain (7 items) and a section on activities of daily living (10 items). Scores range from 0 to 100 with a score of 0 indicating a worse shoulder condition and 100 indicating a better shoulder condition. The survey will be administered to both groups at 2 weeks, 6 weeks, 12 weeks, 6 months, 1 year, and 2 years. The results of these scores will be compared between the two groups at each time point.
- Postoperative complication [2 years]
the 2 year postoperative complications will be recorded and compared between the 2 cohorts.
- Tuberosity Healing on Radiographs [2 years]
Radiographic outcomes regarding the degree of tuberosity healing will be obtained at each postoperative visit until the 2 year mark and compared between the 2 cohorts After initial imaging, patients will receive subsequent X-rays to monitor tuberosity healing, progression of fracture gap closure with bone formation, and signs of bone resorption. Healing is defined as lack of displacement with consolidation of the fracture and disappearance of previous fracture lines. Displacement will be measured in millimeters compared to position on previous xrays.
