AI Article Synopsis
- The study aimed to compare the effectiveness of a specialized radiographic projection (DPr-PaDiO) and computed tomography (CT) in assessing the morphology of distal border synovial invaginations in horse forefeet.
- Results showed that CT identified significantly more invaginations than radiography, with an average difference of 1.2; however, both methods had moderate to good agreement on the shape of the invaginations.
- The findings suggest that the DPr-PaDiO radiographic projection is not reliable for evaluating these specific invaginations due to its limitations in number and depth assessment compared to CT.
Article Abstract
Objectives: To compare the difference and agreement of the morphology of distal border synovial invaginations on a dorsoproximal-palmarodistal oblique (DPr-PaDiO) projection with hoof-specific angle versus computed tomography.
Methods: Computed tomography (CT) images and a DPr-PaDiO radiographic projection with hoof-specific angle were obtained on 50 cadaveric forefeet from 25 Warmblood horses. Computed tomography was assumed to be the gold standard. The number, shape and depth of penetration of distal border synovial invaginations into the distal sesamoid bone were evaluated with both methods, and the comparison of their measurements was statistically described.
Results: Significantly more invaginations were seen on CT compared to radiography, with an observed average difference of 1.2. In none of the cases did radiography have a higher number than that observed with CT. No statistically significant difference for depth between CT and the DPr-PaDiO projection was seen, however, there was quite a large variation of the actual difference of measurements against their mean found. Radiography was underestimated when high mean values applied. The agreement between both modalities for shape was moderate to good. A very high specificity of the specific DPr-PaDiO projection for shape was found (97%).
Clinical Significance: The radiographic projection with hoof-specific angle differs significantly from CT concerning the number and depth of the distal border synovial invaginations. Therefore, this specific view may not be considered useful in the evaluation of these invaginations.

Background: Medial tibial stress syndrome (MTSS) is a common overuse injury characterized by activity-induced pain along the distal medial tibial border. Current best practice includes rest and progressive resistance training. However, some patients with MTSS may be unable to tolerate the loading during exercise.

Radial longitudinal deficiency III and IV present as a short upper limb, functional elbow, and wrist with severe radial and palmar angulation, where the carpus articulates with the radial and palmar edge of the ulna, allowing limited mobility in a nonfunctional position. Surgical treatment aims to correct radial angulation and flexed carpal position, often altering carpal positioning over the distal ulna and impacting wrist mobility. In addition, fixation through distal ulnar epiphysis affects its growth.

The long thoracic nerve's (LTN) superficial location on the chest wall renders it vulnerable to iatrogenic injury. Plastic surgeons' gender-affirming mastectomy volumes are rapidly increasing. This operation involves lateral chest contouring placing the distal LTN at risk of injury along the chest wall.

Article Synopsis
- Primary leiomyosarcoma in bone is a rare tumor that mainly occurs in older adults and may be a metastasis; it requires careful evaluation and broad surgical excision as treatment.
- A case study describes a 50-year-old man with a painful mass in his left wrist, diagnosed with primary leiomyosarcoma of the distal ulna and treated with wide resection and stabilization.
- This type of tumor, although uncommon, should be considered when diagnosing lytic aggressive bone lesions in middle-aged patients, with surgery being the primary treatment method.
