Complications and Functional Outcomes after Subcapital Humerus Fractures

Recruitment & Eligibility

Status: Completed

Sex: Not specified

Target Recruitment: 68

Inclusion Criteria

Patients with subcapital humerus fractures treated non-operatively are eligible
for the study. A subcapital humerus fracture is defined as a two-part surgical
neck fracture, regardless of the degree of fragment displacement.
Non-operative treatment includes sling immobilization followed by gradual
mobilization. The study will evaluate the results of adults and older adults.
The adult cohort encompasses patients between 18 and 65 years of age. The older
adult cohort encompasses patients of at least 65 years of age.

Adults (18- 65 years of age):
Patients with subcapital humerus fractures treated non-operatively and minimum
follow up length of 2 years will be included. In order to be eligible to
participate in this study, a subject must meet all of the following criteria:
1. Men or women of between 18 and 65 years of age upon the first presentation
at the Emergency Department.
2. Written informed consent to participate in the study

Older adults (at least 65 years of age):
Patients with a subcapital humerus fracture treated non-operatively and a
minimum follow up length of 2 year will be included. In order to be eligible to
participate in this study, a subject must meet all of the following criteria:
1. Men or women of at least 65 years of age upon the first presentation at the
Emergency Department.
2. Written informed consent to participate in the study

Exclusion Criteria

Adults (18- 65 years of age):
A potential subject who meets any of the following criteria will be excluded
from participation in this study:
1. Patients less than 2 years of follow up time (the mean time for bone
consolidation is 2 years)
2. Patients presented to the emergency department more than 1 month after
injury (a delay in adequate treatment may affect functional shoulder outcomes)
3. Patients with an open fracture
4. Patients with neurovascular injury
5. Patient with concomitant injuries of the affected shoulder
6. Incapacitated patients
7. Patients with a shoulder arthroplasty in the contralateral shoulder
8. Patients with a nerve injury and concomitant motor function impairment of
the contralateral shoulder
9. Patients with a medical history of a proximal humerus or clavicle fracture
in the contralateral shoulder
10. patients with a severely decreased shoulder function due to any other
medical condition of the contralateral shoulder at the time of the outpatient
visit

Older adults (at least 65 years of age):
A potential subject who meets any of the following criteria will be excluded
from participation in this study:
1. Patients less than 2 years of follow up time (the mean time for bone
consolidation is 2 years)
2. Patients presented to the emergency department more than 1 month after
injury (a delay in adequate treatment may affect functional shoulder outcomes)
3. Patients with an open fracture
4. Patients with neurovascular injury
5. Patients with concomitant injuries of the affected shoulder
6. Incapacitated patients
7. Patients with a shoulder arthroplasty in the contralateral shoulder
8. Patients with a nerve injury and concomitant motor function impairment of
the contralateral shoulder
9. Patients with a medical history of a proximal humerus or clavicle fracture
in the contralateral shoulder
10. patients with a severely decreased shoulder function due to any other
medical condition of the contralateral shoulder at the time of the outpatient
visit

Primary Outcome Measures

Name	Time	Method
<p>Primary outcome: the Constant Murley Score. The CMS is a score ranging from 0<br /><br>to 100 to evaluate the function of both shoulders. A higher score represents a<br /><br>better shoulder function. The CMS consists of four domains: pain (0-15),<br /><br>activities in daily living (0-10), mobility (0-50) and strength (0-25). To<br /><br>determine mobility the pain-free range of shoulder abduction, forward flexion,<br /><br>external rotation and internal rotation is tested. The shoulder strength is<br /><br>measured at 90 degrees in abduction.</p><br>
