Abstract

Background:

Reverse shoulder arthroplasty (rTSA) and anatomic total shoulder arthroplasty (aTSA) treat glenohumeral osteoarthritis (GHOA) with comparable early outcomes. Given increasing utilization of rTSA for GHOA, we sought to evaluate outcomes of rTSA and aTSA for GHOA at early and midterm follow-up.

Methods:

A retrospective propensity-matched cohort study of patients undergoing aTSA and rTSA for GHOA with early and midterm follow-up was performed. Matching included age, sex, body mass index, preoperative American Shoulder and Elbow Surgeons (ASES) score, preoperative forward elevation, and Walch glenoid morphology. Baseline patient characteristics, range of motion, ASES, Single Assessment Numeric Evaluation (SANE), visual analog scale (VAS) for pain scores, complications and revision rTSAs/aTSAs were assessed at early and midterm follow-up.

Results:

One hundred twenty-two patients (61 per group) were included with early and midterm follow-up. Baseline characteristics, comorbidities, preoperative ASES, SANE, VAS pain scores, and range of motion were similar (P > .05). Both groups showed significant improvements in ASES, SANE, and VAS scores at both time points (P < .001); >96% achieved minimal clinically important difference for ASES. While more aTSA patients met substantial clinical benefit early (95.1% vs. 80.3%, P = .027); there was no statistically significant difference at midterm follow-up (P = .074). aTSA patients had better early internal (5.0 vs. 3.3, P < .001) and external rotation (63.0° vs. 57.0°, P = .036), with no difference at midterm follow-up. Complication rates were similar; however, aTSA had more revisions and radiolucencies.

Conclusion:

aTSA and rTSA yield similar clinical outcomes for GHOA at early and midterm follow-up. Early differences in substantial clinical benefit, internal, and external rotation with aTSA diminished by midterm follow-up. Complication rates were similar between the cohorts. One patient in the aTSA group was revised to rTSA and no patients with primary rTSA required revision. While rTSA and aTSA result in excellent clinical outcomes, longer follow-up is needed to determine durability.

Muscles of the Shoulder

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Sign Test for Matched Pairs

Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
