Randomized Controlled Trial Multicenter Study
The association between Modic changes and pain during 1-year follow-up in patients with lumbar radicular pain.
To examine whether Modic changes influence pain during a 1-year follow-up in patients with lumbar radicular pain. ⋯ Patients with lumbar radicular pain have a substantial pain reduction during 1-year follow-up, but Modic type I changes may imply a slower initial decrease in sensory pain.

Randomized Controlled Trial Multicenter Study
Do more MRI findings imply worse disability or more intense low back pain? A cross-sectional study of candidates for lumbar disc prosthesis.
To examine whether combined magnetic resonance imaging (MRI) findings are related to the degree of disability and low back pain (LBP) in candidates for lumbar disc prosthesis surgery. ⋯ The combined MRI findings were not related to the degree of disability or the intensity of LBP. These degenerative MRI findings cannot explain variation in pre-treatment disability and pain in patients with chronic LBP accepted for disc prosthesis surgery.

Randomized Controlled Trial
Multiplanar reconstruction computed tomography for diagnosis of scaphoid waist fracture union: a prospective cohort analysis of accuracy and precision.
To examine reliability and validity concerning union of scaphoid fractures determined by multiplanar reconstruction computed tomography randomized at 6, 12, and 24 weeks after injury. ⋯ Our results suggest that multiplanar reconstruction computed tomography is a reliable and accurate method for diagnosing union or nonunion of scaphoid fractures. However, inter-observer agreement was lower with respect to partial union.

The Radiographic Union Score for Hip (RUSH): the use of a checklist to evaluate hip fracture healing improves agreement between radiologists and orthopedic surgeons.
The assessment of fracture healing following intertrochanteric fracture fixation is highly variable with no validated standards. Agreement with respect to fracture healing following surgery is important for optimal patient management. The purpose of this study was to (1) assess reliability of intertrochanteric fracture healing assessment and (2) determine if a novel radiographic scoring system for hip fractures improves agreement between radiologists and orthopedic surgeons. ⋯ The RUSH score improves agreement of fracture healing assessment between orthopedic surgeons and radiologists, offers a systematic approach to evaluating intertrochanteric hip fracture radiographs, and may ultimately provide prognostic information that could predict healing outcomes in patients with femoral neck fractures.

Randomized Controlled Trial
Ultrasound-guided selective nerve root block versus fluoroscopy-guided transforaminal block for the treatment of radicular pain in the lower cervical spine: a randomized, blinded, controlled study.
To compare the short-term effects and advantages of ultrasound-guided selective nerve root block with fluoroscopy-guided transforaminal epidural block for radicular pain in the lower cervical spine through assessment of pain relief, functional improvement, and safety. ⋯ The US-guided method may facilitate identifying critical vessels at unexpected locations relative to the intervertebral foramen and avoiding injury to such vessels, which is the leading cause of the reported complications from cervical transforaminal injections. On treatment effect, using either method of epidural injections to deliver steroids for cervical radicular pain, secondary to herniated intervertebral disc or foraminal stenosis, significant improvements in function and pain relief were observed in both groups after the intervention. However, significant difference was not observed between the groups. Therefore, the ultrasound-guided method was shown to be as effective as the fluoroscopy-guided method in pain relief and functional improvement, in addition to the absence of radiation and avoiding vessel injury at real-time imaging.
