Clinical Trial Summary

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 .

Description:

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?

Eligibility

Inclusion Criteria:

1. Displaced 2- or 3-part proximal humerus fractures by the Neer classification.

2. Displaced 4-part proximal humeral fractures by the Neer classification that are deemed amenable to surgical fixation.

3. > 60 years of age

4. Low energy mechanism of injury

5. Acute fracture (<3 weeks)

Exclusion Criteria:

1. 4-part proximal humerus fractures that are not deemed amenable to surgical fixation (eg. due to osteopenic bone, thin head or tuberosity fragments); fractures that are better suited to treatment with arthroplasty

2. Isolated greater tuberosity fractures

3. Ipsilateral upper extremity significant injury, concomitant fracture or polytrauma

4. Open fracture

5. Previous ipsilateral shoulder surgery

6. Patients with active worker's compensation claims (due to the expectation of lower rates of success in this patient population)

7. Active joint or systemic infection

8. Patients with convulsive disorders, collagen diseases, and any other conditions that might affect the mobility of the shoulder joint

9. Major medical illness (life expectancy less than 2 years, unacceptably high operative risk, or not medically cleared by preoperative anesthesia consult)

10. Unable to speak or read English/French

11. Psychiatric illness that precludes informed consent

12. Unwilling to be followed for 2 years

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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).	From baseline to up until 24-Months Post-Operative
Secondary	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.	From baseline to up until 24-Months Post-Operative
Secondary	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.	From baseline to up until 24-Months Post-Operative
