Purpose:
Arthritis of the first carpometacarpal (CMC) joint affects up to 15% of the population aged over 30 years and 40% of the population aged over 50 years. Arthroplasty of the first CMC joint is a widely accepted treatment option for these patients, with most patients doing well long term despite radiographic evidence of subsidence. Postoperative treatment protocols vary with no defined gold standard, and the need for routine postoperative radiographs has not been defined. The purpose of this study was to evaluate the use of routine postoperative radiographs following CMC arthroplasty.
Methods:
A retrospective review of patients who underwent CMC arthroplasty from 2014 to 2019 at our institution was performed. Patients receiving a concomitant trapezoid resection or metacarpophalangeal capsulodesis/arthrodesis were excluded. Demographic data, as well as the frequency and timing of postoperative radiographs, were collected. Radiographs were included if taken up to 6 months from the date of surgery. The primary outcome was a repeated operative intervention. Descriptive statistics were used for the analysis.
Results:
A total of 155 CMC joints from 129 patients were included in the study. Sixty-one (39.4%) patients had no postoperative radiographs, 76 (49.0%) patients had one postoperative radiographic series, 18 (11.6%) had two, 8 (5.2%) had three, and 1 (0.6%) patient had four postoperative series of radiographs. A radiographic series is defined as multiple views taken at a single time point. Four of 155 (2.6%) patients underwent additional operative intervention. There were no patients who underwent revision CMC arthroplasty. Two had wound infections that underwent irrigation and debridement. Two developed metacarpophalangeal arthritis and underwent arthrodesis. There were no cases where repeat operative intervention was driven by postoperative radiographic findings.
Conclusions:
Routine postoperative radiographs following CMC arthroplasty do not lead to changes in patient management, specifically further surgery. These data may support forgoing routine radiographs in the postoperative period following CMC arthroplasty.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
