Summary
This study introduces a new X-ray technique for examining the hip joints of standing cattle. The improved method enhances the evaluation of coxofemoral region injuries in cattle.
Area of Science:
- Veterinary Radiology
- Bovine Orthopedics
Background:
- Radiographic evaluation of the coxofemoral joint in cattle presents challenges.
- Accurate assessment of hip joint injuries is crucial for diagnosis and treatment.
Purpose of the Study:
- To establish and validate a radiographic technique for examining the coxofemoral joint and adjacent structures in standing cattle.
- To determine the optimal X-ray beam angle for minimizing distortion and superimposition.
Main Methods:
- Retrospective evaluation of standing radiographic views (30° dorsal-right/left ventral) in 10 lame cattle.
- Experimental study using a bovine skeleton to test oblique laterolateral views at varying angles (15-45°).
Main Results:
- The technique allowed assessment of the ilium, ischium, acetabulum, and proximal femur.
- Identified various injuries including ilial/ischial fractures, hip luxations, and femoral neck fractures.
- An X-ray beam angle of 25° to the horizontal plane minimized distortion and superimposition.
Conclusions:
- The described laterodorsal-lateroventral radiographic technique is suitable for evaluating the coxofemoral joint and related structures in standing cattle.
- The technique, with the optimal 25° angle, can also be applied to recumbent cattle.
- This method improves the diagnostic evaluation of coxofemoral region injuries in cattle.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:11Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
