From the Guidelines
The subtle cortical irregularity at the volar aspect of the pisiform is located on the palm-facing surface of the pisiform bone, which is a small, pea-shaped sesamoid bone in the wrist. This irregularity refers to a slight disruption or unevenness in the outer layer (cortex) of the bone on the side that faces the palm. The pisiform bone is positioned on the ulnar (pinky finger) side of the wrist, where it articulates with the triquetrum bone and serves as an attachment point for several ligaments and the flexor carpi ulnaris tendon. Such cortical irregularities may represent normal anatomical variation, a response to repetitive stress, or occasionally early signs of pathology such as arthritis or prior trauma. This finding is often incidental on imaging studies like X-rays or MRIs and may not be clinically significant unless associated with symptoms such as pain, swelling, or limited range of motion in the wrist, as noted in studies on hand and wrist trauma 1, 2, 3. Key points to consider include:
- The pisiform bone's location and function in the wrist
- The potential causes of cortical irregularities, including normal variation, repetitive stress, and pathology
- The importance of considering symptoms and clinical significance when evaluating this finding
- The role of imaging studies, such as X-rays and MRIs, in detecting and characterizing cortical irregularities. Given the information provided and the focus on morbidity, mortality, and quality of life, it is essential to approach this finding with a thorough clinical evaluation and consideration of the patient's overall condition, rather than relying solely on imaging findings 1.
From the Research
Location of Subtle Cortical Irregularity
- The location of subtle cortical irregularity at the volar aspect of the pisiform is not explicitly mentioned in the provided studies 4, 5, 6, 7, 8.
Relevant Information
- The studies primarily focus on osteoid osteoma, benign bone lesions, and cortical abnormalities, but do not provide specific information about the pisiform bone or its volar aspect.
- The pisiform bone is a small, pea-shaped bone in the wrist, and cortical irregularities in this area could be related to various conditions, but the provided studies do not offer relevant insights.
Available Data
- There is no direct evidence in the provided studies to determine the location or significance of subtle cortical irregularity at the volar aspect of the pisiform.
- Further research or consultation of additional studies may be necessary to gather more information on this topic.
