The aim of this study was to evaluate the safety and efficacy of percutaneous placement of iliosacral screws under the guidance of axial view projection of the S1 pedicle clinically. This case series includes 58 consecutive unstable pelvic injury patients, which were treated with iliosacral screws between July 2011 and July 2016. Patients were divided into two groups: normal sacrum (n = 31) and dysmorphic sacrum (n = 27). A single orthopedic surgeon operated on all patients, with percutaneous placement of iliosacral screws under the guidance of axial view projection of the S1 pedicle...

The development of perceptual skills is an important aspect of veterinary education. The authors investigated veterinary student competency in lameness evaluation at two stages, before (third year) and during (fourth/fifth year) clinical rotations. Students evaluated horses in videos, where horses were presented during trot on a straight line and in circles. Eye-tracking data were recorded during assessment on the straight line to follow student gaze. On completing the task, students filled in a structured questionnaire...

BACKGROUND: Agreement amongst experienced clinicians is poor when assessing presence and severity of ataxia, especially when signs are mild. Consequently, objective gait measurements might be beneficial for assessment of horses with neurological diseases. OBJECTIVES: To assess diagnostic criteria using motion capture to measure variability of spatial gait-characteristics and swing duration derived from ataxic and non-ataxic horses and to assess if variability increases with blindfolding...

BACKGROUND: Gynecologic surgeries are performed through abdominal, vaginal, laparoscopic, or robot-assisted laparoscopic routes. However, if the pelvis is not accessible by one of these routes, there are no published reports to guide pelvic surgeons. CASE: A 34-year-old conjoined twin status postseparation with uterine didelphys and absence of her left colon and sacrum underwent hemihysterectomy, at which time her müllerian anomaly was unknown. She re-presented with vaginal bleeding and pain eventually attributed to a retained uterine horn...

BACKGROUND: Spinal cord transection is a radical but effective treatment for highly selective cases of symptomatic spinal re-tethering in paraplegic spina bifida patients. Autonomic dysreflexia (AD) is a potentially life-threatening syndrome involving a dysregulated sympathetic discharge reflex commonly seen following cervical and high thoracic spinal cord injury leading to a disconnect between autonomic pathways above and below the lesion that can lead to severe complications including uncontrolled hypertension, bradycardia, stroke, and potentially death...

BACKGROUND AND PURPOSE: Multiple methods have been used to determine the lumbar vertebral level on MR imaging, particularly when full spine imaging is unavailable. Because postmortem studies show 95% accuracy of numbering the lumbar vertebral bodies by counting the lumbar nerve roots, attention to lumbar nerve morphology on axial MR imaging can provide numbering clues. We sought to determine whether the L5 vertebra could be accurately localized by using nerve morphology on MR imaging...

Fractures involving the central canal of the sacrum are rare injuries and can be transverse or longitudinal. Transverse fractures are by far common and associated with high incidence of neurological injuries. On the contrary, longitudinal midline split fracture is an extremely rare injury with minimal or no neurological injury. They are always associated with anterior pelvic ring fracture and are vertically stable needing only fixation of the anterior pelvic injury. Plating of the anterior pelvic ring in two planes would be beneficial than single plate to prevent gradual loss of reduction...

Tammy Brockman
"Stringhalt" is a horse condition that causes one or both hind legs to spasm when walking, trotting or backing. The condition is thought to be related to a neurological cause from either plant toxicity or peripheral nerve injury. The prognosis is poor and the horse's performance and quality of life can be affected. Treatment has included surgically cutting the digital extensors with varied results. The objective of the study is to utilize soft tissue release via acupressure, trigger point and myofascial release to decrease symptoms of stringhalt...

BACKGROUND: Colorectal cancer (CRC) resembling submucosal tumor (SMT; CRC/SMT) is very rare. Because its biopsy is challenging, accurate preoperative diagnosis is also very rare. CASE PRESENTATION: A 55-year-old woman with a high serum carcinoembryonic antigen level underwent a computed tomography colonoscopy, which showed extrinsic rectum compression. A coronal magnetic resonance image showed a 4-cm low-intensity tumor between her rectum and sacrum. Endoscopic ultrasound (EUS) showed a 30-mm low-echoic lesion originating from the rectum...

The bony pelvis is constituted by the ilium, ischium, pubis, and sacrum. The pelvic radiograph is an important component of the skeletal survey performed in suspected skeletal dysplasia. Most of the common skeletal dysplasias have either minor or major radiological abnormalities; hence, knowledge of the normal radiological appearance of bony pelvis is vital for recognizing the early signs of various skeletal dysplasias. This article discusses many common and some uncommon radiological findings on pelvic radiographs along with the specific dysplasia in which they are seen; common differential diagnostic considerations are also discussed...
