Clinical, radiographic, ultrasonographic and computed tomographic features of nonseptic osteitis of the axial border of the proximal sesamoid bones.
Abstract: Lysis of the axial aspect of equine proximal sesamoid bones (PSBs) is a rare condition reported to have septic or traumatic origins. Limited information exists regarding imaging of nonseptic axial osteitis of a PSB. Objective: To report the clinical, radiographic, ultrasonographic, computed tomographic and intra-arterial contrast-enhanced computed tomographic abnormalities in horses with axial nonseptic osteitis of a PSB. Methods: Retrospective clinical study. Methods: Eighteen horses diagnosed with nonseptic osteitis of the axial border of a PSB between 2007 and 2012 were reviewed retrospectively. Case details, clinical examination, radiographic, ultrasonographic, computed tomographic and intra-arterial/intra-articular contrast-enhanced computed tomographic features were recorded, when available. Radiographic, ultrasonographic and computed tomographic evaluations of the fetlock region had been performed on 18, 15 and 9 horses, respectively. The effect of the degree of lysis on the grade and duration of lameness was determined. Results: All horses had chronic unilateral lameness, 4 with forelimb and 14 with hindlimb signs. On radiographs, lysis was identified in both PSBs in 14 horses, one PSB in 3 horses and in one horse no lysis was identified. The degree of osteolysis was variable. Ultrasonography identified variably sized irregularities of the bone surface and alteration in echogenicity of the palmar/plantar ligament (PL). All horses undergoing computed tomographic examination (n = 9) had biaxial lysis. The lesions were significantly longer and deeper on computed tomographic images compared with radiographic images. Intra-arterial contrast-enhanced computed tomography may reveal moderate to marked contrast enhancement of the PL. There was no significant effect of the degree of lysis on the grade and duration of lameness. Conclusions: Lesions of nonseptic axial osteitis of a PSB can be identified using a combination of radiography and ultrasonography. Computed tomography provides additional information regarding the extent of the pathology.

This research primarily focuses on nonseptic osteitis of the proximal sesamoid bones in horses. The study evaluates various imaging techniques such as radiography, ultrasonography, computed tomography, and intra-arterial contrast-enhanced computed tomography, for their effectiveness in identifying this condition. It was found that a combination of these imaging techniques can effectively identify the condition and the extent of the pathology.
Study Methods
- Retrospective clinical data from 18 horses diagnosed with nonseptic osteitis of the axial border of a proximal sesamoid bone (PSB) between 2007 and 2012 was analyzed.
- The researchers collected information on the clinical examination, radiographic, ultrasonographic, computed tomographic, and intra-arterial/intra-articular contrast-enhanced computed tomographic features from each case where data was available.
- They also assessed the effect of the degree of lysis (bone loss) on the grade and duration of lameness in horses.
Study Results
- All the horses studied had chronic unilateral lameness; with 4 horses showing signs in the forelimb and 14 in the hindlimb.
- Radiographic imaging revealed lysis in both PSBs in 14 horses, one PSB in 3 horses, and no lysis was identified in one horse.
- Ultrasonography showed variable sized irregularities on the bone surface and changes in the echogenicity of the palmar/plantar ligament.
- Computed tomography, conducted on 9 horses, revealed biaxial lysis in all cases and the resulting lesions were found to be significantly longer and deeper compared to those visible in radiographic images.
- Intra-arterial contrast-enhanced computed tomography showed moderate to marked contrast enhancement of the palmar/plantar ligament.
- The degree of lysis had no significant effect on the grade and duration of lameness in the studied horses.
Study Conclusions
- The study concluded that nonseptic axial osteitis of a PSB can be effectively identified using a combination of radiography and ultrasonography.
- Computed tomography was found to provide additional and valuable information regarding the extent of the pathology.
