Background: Cauda equina syndrome (CES) is a rare complication of spinal or epidural anesthesia. It is attributed to direct mechanical injury to the spinal roots of the cauda equina that may result in saddle anesthesia and paraplegia with bowel and bladder dysfunction. Case Description: The first patient underwent a hip replacement and received 5 mL of 1% lidocaine epidural anesthesia. Postoperatively, when the patient developed an acute CES, the lumbar magnetic resonance imaging (MRI) scan demonstrated clumping/posterior displacement of nerve roots of the cauda equina consistent with adhesive arachnoiditis attributed to the patient's previous L4-L5 lumbar decompression/fusion...

BACKGROUND: Rotational acetabular osteotomy (RAO) is one of the surgical treatments for acetabular dysplasia, and satisfactory results have been reported. We evaluated the postoperative changes of articular cartilage and whether the pre-operative condition of the articular cartilage influences the clinical results using T2 mapping MRI. METHODS: We reviewed 31 hips with early stage osteoarthritis in 31 patients (mean age, 39.6 years), including three men and 28 women who underwent RAO for hip dysplasia...

BACKGROUND: Evaluation and management of osteochondral lesions of the talus (OLTs) often warrant advanced imaging studies, especially in revision or cases with cystic defects. It is possible that orthopedic surgeons may overestimate the size and misinterpret the morphology of OLT from conventional computed tomography (CT), thereby influencing treatment strategies. The purpose of this study was to determine the utility of a novel means to estimate the true-volume of OLTs using 3D reconstructed images and volume analysis...

Previous studies have shown compensatory adaptive changes in cerebral functions before surgery in patients with cervical spondylotic myelopathy (CSM), especially in the sensorimotor cortices. However, the structural changes in the sensorimotor cortices in patients with CSM remain poorly understood. The aim of this study was to assess the volumetric changes in the sensorimotor cortices using morphological MRI and to correlate these changes with clinical scales. We hypothesize that CSM causes atrophy in the sensorimotor cortices, which results in functional changes during CSM progression...

We evaluated the accuracy of the predictive injury sequences of the Lauge-Hansen (L-H) classification using magnetic resonance imaging (MRI) in patients with ankle fractures and determined the possible causes of mismatch. Sixty-five patients with ankle fractures who had a complete series of anteroposterior, lateral, and oblique radiographs and ankle MRI studies available were included. The fracture pattern was assigned by 2 senior orthopedic surgeons according to the L-H classification system. The syndesmotic ligaments, lateral collateral ligaments, and medial deltoid complex ligaments were evaluated on the preoperative MRI scans...

BACKGROUND: Patients with mild degenerative cervical myelopathy (DCM) are often managed non-operatively, and surgery is recommended if neurological progression occurs. However, detection of progression is often subjective. Quantitative MRI (qMRI) directly measures spinal cord (SC) tissue changes, detecting axonal injury, demyelination, and atrophy. This longitudinal study compared multiparametric qMRI with clinical measures of progression in non-operative DCM patients. METHODS: 26 DCM patients were followed...

STUDY DESIGN: Case-control. OBJECTIVE: The aim of this study was to understand the role of high-resolution magnetic resonance (MR) in identifying regional cord volume loss in cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA: Preliminary studies suggest that compression of the ventral region of the cord may contribute disproportionately to CSM symptomology; however, tract-specific data are lacking in the CSM population. The current study is the first to use 3T MR imaging (MRI) images of CSM patients to determine specific volume loss at the level of detail of individual descending white matter tracts...

PURPOSE: For guidance of orthopedic surgery, the registration of preoperative images and corresponding surgical plans with the surgical setting can be of great value. Ultrasound (US) is an ideal modality for surgical guidance, as it is non-ionizing, real time, easy to use, and requires minimal (magnetic/radiation) safety limitations. By extracting bone surfaces from 3D freehand US and registering these to preoperative bone models, complementary information from these modalities can be fused and presented in the surgical realm...

Background: It is important to diagnose a scaphoid fracture accurately and start the correct treatment in the shortest time possible. However, the fracture of bone may not be visible on x-ray. In such cases, patients are clinically diagnosed with suspected or occult scaphoid fractures. The aim of this study was to define a scoring system based on physical examination to demonstrate the risk for bone injury in patients with clinically suspected and occult scaphoid fractures with negative radiographs and anatomical snuff box tenderness and to decrease the costs and workforce loss due to unnecessary treatment and magnetic resonance imaging (MRI)...

Spontaneous bilateral quadriceps tendon rupture is a rare finding in emergency departments. Thus, the pathophysiology is not well understood. Imaging for improved speed of diagnosis is rarely considered. We present a case of non-traumatic spontaneous bilateral quadriceps tendon rupture and examine current literature on the pathophysiology and imaging guidelines on the topic. The patient is a 49-year-old male that presented to the emergency department with bilateral thigh pain. He had been seen earlier with similar pain, but now presents with increased difficulty ambulating...

BACKGROUND: Removing the posterior longitudinal ligament in cervical corpectomy is a controversial issue. It is unclear whether the risks are counterbalanced by clinical benefits. Another unexplored topic is whether the width of the corpectomy affects outcome. METHODS: This cross-sectional retrospective study included consecutive patients who underwent cervical corpectomy for spondylosis by 6 different neurosurgeons. We compared 2 groups, where the posterior longitudinal ligament was either removed (N = 15 patients) or preserved (N = 21 patients)...
