Risk factors for tibial stress injuries: a case-control study.

Objective: To identify physical and behavioral characteristics related to the incidence of tibial stress injuries (TSIs).

Design: Case-control study. No clinical care was conducted.

Tibial stress injury: relationship of radiographic, nuclear medicine bone scanning, MR imaging, and CT Severity grades to clinical severity and time to healing.

Purpose: To examine the relationship between severity grade for radiography, triple-phase technetium 99m nuclear medicine bone scanning, magnetic resonance (MR) imaging, and computed tomography (CT); clinical severity; and recovery time from a tibial stress injury (TSI), as well as to evaluate interassessor grading reliability.

Materials And Methods: This protocol was approved by the Griffith University Human Research Ethics Committee, the Stanford University Panel on Human Subjects in Medical Research, the U.S.

Do capacitively coupled electric fields accelerate tibial stress fracture healing? A randomized controlled trial.

Background: Tibial stress fractures increasingly affect athletes and military recruits, with few known effective management options. Electrical stimulation enhances regular fracture healing, but the effect on stress fractures has not been definitively tested.

Hypothesis: Capacitively coupled electric field stimulation will accelerate tibial stress fracture healing.

The flexor hallucis longus: tenographic technique and correlation of imaging findings with surgery in 39 ankles.

Purpose: To examine the use of tenography for evaluation of the flexor hallucis longus (FHL) sheath.

Materials And Methods: Institutional review board approval was waived, patient consent was obtained, and the study was HIPAA compliant. Retrospective review of 192 FHL tenograms and associated surgical records identified 39 ankles in 37 patients (17 male, 20 female; mean age +/- standard deviation, 38 years +/- 13.

Asymptomatic tibial stress reactions: MRI detection and clinical follow-up in distance runners.

Objective: The purpose of this study was twofold: to determine if asymptomatic elite distance runners exhibit stress reactions of the tibia on MR images and to determine if the presence of bone stress lesions predicts later development of symptomatic tibial stress injuries.

Conclusion: Signs of a tibial stress reaction were found on MRI in 43% of the 21 asymptomatic college distance runners in this study. The presence of these changes was not found to be a predictor of future tibial stress reactions or stress fractures.

Segmental mobility of the lumbar spine during a posterior to anterior mobilization: assessment using dynamic MRI.

Objectives: To quantify segmental mobility of the lumbar spine during a posterior to anterior spinal mobilization procedure.

Design: Descriptive study using dynamic magnetic resonance imaging.

Background: The posterior to anterior spinal mobilization procedure is frequently used in the assessment and management of spinal dysfunction.

Risk factors for progressive cartilage loss in the knee: a longitudinal magnetic resonance imaging study in forty-three patients.

Objective: To evaluate the rate of progression of cartilage loss in the knee joint using magnetic resonance imaging (MRI) and to evaluate potential risk factors for more rapid cartilage loss.

Methods: We evaluated baseline and followup MRIs of the knees in 43 patients (minimum time interval of 1 year, mean 1.8 years, range 52-285 weeks).

Interventional musculoskeletal procedures performed by using MR imaging guidance with a vertically open MR unit: assessment of techniques and applicability.

Purpose: To evaluate the safety of and time required for a broad range of musculoskeletal interventional procedures performed by using magnetic resonance (MR) imaging guidance with a vertically open 0.5-T unit.

Materials And Methods: Sixty-three MR imaging-guided procedures were performed.

Videofluoroscopic evaluation of prosthetic fit and residual limbs following transtibial amputation.

The clinical examination of residual limb complications is usually subjective and may lead to inappropriate, expensive adjustments or replacement of the prosthesis. Plain films and xeroradiography only provide static images of the residual limb and socket. The purpose of this pilot study was to develop a videofluoroscopic technique to evaluate dynamic residual limb-socket relationships during gait.
