Abstract

Recently the use of reverse shoulder arthroplasty (RSA) has increased because of a clinical perception of durable functional outcome. However, some patients unexpectedly have a poor recovery of range of motion (ROM) after surgery. Objective factors such as initial diagnosis, pre- and intra-operative ROM, deltoid impairment or arm lengthening have previously been associated with anterior forward flexion (AFF). This study sought to determine if subjective pre-operative factors influence the rate and timing of ROM recovery after RSA. Between January 2011 to January 2012, all RSAs performed by a single surgeon were prospectively enrolled in this study. The cohort was divided into two groups based on AFF <90 or ≥90 after surgery. A multivariate analysis was performed to define independent predictive factors of post-operative ROM. Factors assessed included: age, sex, dominant arm, patient activity, body mass index (BMI), pre-operative diagnosis, deltoid status, pain and Constant scores, subjective shoulder value (SSV), simple shoulder test (SST) and radiographic findings. Patients were reviewed at six weeks, and three, six, 12 and 24 months. One hundred and one RSAs were available for analysis. Poor post-operative AFF at six weeks was significantly related to poor pre-operative deltoid strength. Poor post-operative AFF at one-year follow-up was related to surgery of non-dominant arm, pre-operative poor AFF, pre-operative activity, poor subjective shoulder value (SSV), and a low contralateral Constant score. AFF and Constant score improved until six months and then plateaued. In contrast, both external and internal rotation continued to improve beyond six months after surgery. AFF and Constant scores after RSA plateau at six months after surgery whereas internal and external rotation continue to improve up to two years post operation. Several pre-operative factors including poor pre-operative AFF, surgery on the non-dominant arm, and lower SSV and Constant scores are correlated with post-operative ROM following RSA. Identification of these factors may be useful for counseling on functional expectations as well as customizing rehabilitation plans. Level II, Prospective Cohort Study, Treatment Study.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 March 2018.
All research outputs
#10,097,242
of 12,622,988 outputs
Outputs from International Orthopaedics
#643
of 882 outputs
Outputs of similar age
#205,253
of 273,752 outputs
Outputs of similar age from International Orthopaedics
#14
of 18 outputs
Altmetric has tracked 12,622,988 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 882 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 12th percentile – i.e., 12% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 273,752 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
