An interventional study of Non operative and locking plate surgical fixation in Proximal Humerus Fracture, sponsored by Ottawa Hospital Research Institute. Terminated at 1 site in Canada. Open to participants aged 60 Years and older. Per ClinicalTrials.gov, last updated 2021-05-17.
Sponsored by Ottawa Hospital Research Institute · Not applicable, Interventional, and Treatment
The primary objective is to determine if a difference exists in functional outcomes, as measured by the Constant score, when comparing nonoperative management and locking plate surgical fixation of low-energy displaced proximal humerus fractures in the elderly population over a 2-year follow-up period. Secondary outcomes will include an assessment of the ASES score, the SF-36 quality of life score, complication rates, re-operation rates, radiographic time to union, radiographic malunion, hardware position and evidence of avascular necrosis or posttraumatic osteoarthritis .
The design of this study is two-fold. The main study will be a prospective, single blind, randomized controlled trial (RCT). Patients will be randomized to either (1) non-operative treatment or (2) locking plate open reduction and internal fixation (ORIF).
The second component of this study will be a prospective, cohort study. This option will be presented to patients who do not want to enroll in the RCT because they prefer one treatment option over the other, and do not wish to be randomized to a treatment. Patients who choose either non-operative treatment or ORIF for their proximal humerus fracture will be followed for 2 years post injury.
Study Objectives:
Objective 1: Does a difference exist in the functional outcome between non-operative management and locking plate surgical fixation of low-energy displaced two-part, three-part, and four-part proximal humerus fractures in the elderly population based on the Constant functional outcome score over a 2-year follow-up period? Objective 2: Does a difference exist between non-operative management and locking plate surgical fixation of low-energy displaced two-part, three-part, and four-part proximal humerus fractures in the elderly population based on the ASES functional outcome score, the short form Patient Reported Outcomes Measurement Information System (PROMIS) upper extremity score, the International Physical Activity Questionnaire (IPAQ) for the elderly, and the EuroQol EQ-5D-5L Health Questionnaire Quality of Life (QoL) functional outcome score over a 2-year follow-up period? What is the incidence of complications of non-operative management and locking plate surgical fixation of low-energy displaced two-part, three-part, and four-part proximal humerus fractures in the elderly population based on infection, nerve injury, intra-articular screw penetration and bleeding (hematoma), reoperation rate, or hospital readmission over a 2-year follow-up period? Objective 3: Does a difference exist between non-operative management and locking plate surgical fixation of low-energy displaced two-part, three-part, and four-part proximal humerus fractures in the elderly population based on radiographic outcomes including non-union, malunion, and joint arthrosis? Objective 4: Does the degree of initial displacement or angulation of the fracture fragments correlate with final functional outcome measures? Objective 5: Does the quality of the surgical reduction correlate with final functional outcome measures?

Exclusion Criteria:
Treatment will consist of sling immobilization for a period of 6 weeks. Details and treatment timeline as follows: * 0 - 3 weeks: immobilization with a shoulder sling, range of motion of elbow, hand and wrist * 3 - 6 weeks: same as 0-3 weeks, with addition of pendulum exercises every two hours * After 6 weeks: Active mobilization and removal of sling. Light activity permitted and physiotherapy for range of motion permitted as tolerated. * After 6 months: no further restriction will be placed. Full home and work activity permitted.
Other: Non operative
Standardized operative management protocol as follows: * Pre-operative medical clearance established via anesthesia consults if required for medically complex patients. * Provision of pre-operative intravenous (IV) antibiotic prophylaxis: * Administration of general anesthetic. * Patient positioning and preparation: * Patient is carefully placed in the beach-chair position, * Deltopectoral approach Fracture reduction and fixation with confirmation with intraoperative fluoroscopy images.

Change in Constant Score
The Constant Score reflects an overall clinical functional assessment. This instrument is based on a 100-point scoring system. Subjective findings (pain, activities of daily living, and working in different positions) make up a total of 35 points. Objective measurements make up the remaining 65 points.The test is divided into four sub-categories: (1) pain is measured using 4 likert levels (15 points maximum), where a higher score indicates a better outcome; activities of daily living are measured using a likert scale, where a higher number indicates better outcomes (20 points maximum); mobility is measured by an assessor, and rated using a likert scale where a higher score indicates better outcomes (40 points maximum); finally, strength is measured by an assessor where 1 point is given per 0.5kg of force (maximum 25 points), a higher score indicates better outcomes. All categories are added together, and a total score out of 100 is given (higher score indicates better outcome).
Time frame: From baseline to up until 24-Months Post-Operative
Change in American Shoulder and Elbow Surgeons Standardized Shoulder Assessment
The ASES is a shoulder specific assessment divided into two sections: pain and activities of daily living (ADL). Pain is recorded on a visual analogue scale (0-10), lower scores indicate better outcomes. There are 10 activities of daily living questions, each are recorded on a 4 level likert scale (0-3), which a higher score indicates a better outcome. The overall score is an equal weight of the two sections and produces a score out of 100. The higher the score, the better the outcome.
Time frame: From baseline to up until 24-Months Post-Operative
Change in Short Form-36
The Short Form 36 (SF-36) is an outcome measure used to determine quality of life. This measure has 8 scaled scores, each question has equal weight and is then translated onto a scale graded from 0-100. A higher number indicates a better outcome.
Time frame: From baseline to up until 24-Months Post-Operative
