This narrative review presents commonly used radiographic parameters in shoulder surgery. The review outlines the historical context, definitions, and evidence regarding diagnostic and prognostic utility of each measurement. Limitations such as variability in imaging technique and lack of standardized measurement protocols are discussed. Despite these constraints, these measurements remain central to evaluating imaging of the shoulder, guiding implant positioning, assessing pathology, and comparing outcomes across studies.

Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Pre-Procedural Guidelines for Assessing Blood Pressure
Assessment of blood pressure in brachial artery(one-step method)
Prepare for the Procedure:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
