Grant Buchanan, LeeAnne Torres, Brian Czarkowski, Charles E Giangarra
: Patellofemoral instability is a painful and commonly recurring condition, which often must be managed surgically. Diagnosis can be aided by the use of a variety of physical exam signs, such as the Q angle, Beighton hypermobility score, glide test, J sign, patellar tilt test, and apprehension test. Imaging modalities including x-ray, CT, and MRI guide both diagnosis and management by revealing trochlear dysplasia, bony malalignment, and ligamentous injury that contribute to instability...

The pelvis bone resection-reconstruction surgery is one of the most challenging fields in orthopedics. Being applied for tumors, as for other complex reconstruction cases, this type of surgery needs careful planning and is time consuming, in order to obtain proper accuracy. Unfortunately not all the time the expected accuracy is met, with consequences for the patients. PSI proved to provide good cutting accuracy during simulated tumor surgery within the pelvis. This article present a series of 4 patients operated in our department between June 2014 and Mars 2015 for tumors resectionreconstructions...

Anterior cruciate ligament (ACL) reconstruction is one of the most common orthopedic procedures performed worldwide. In this regard, magnetic resonance imaging (MRI) represents a useful pre-operative tool to confirm a disruption of the ACL and to assess for potential associated injuries. However, MRI is also valuable post-operatively, as it is able to identify, in a non-invasive way, a number of aspects and situations that could suggest potential problems to clinicians. Graft signal and integrity, correct tunnel placement, tunnel widening, and problems with fixation devices or the donor site could all compromise the surgical outcomes and potentially predict the failure of the ACL reconstruction...

Ultrasound and magnetic resonance imaging (MRI) are both capable of diagnosing full-thickness rotator cuff tears. However, it is unknown which imaging modality is more accurate and precise in evaluating the characteristics of full-thickness rotator cuff tears in a surgical population. This study reviewed 114 patients who underwent arthroscopic repair of a full-thickness rotator cuff tear over a 1-year period. Of these patients, 61 had both preoperative MRI and ultrasound for review. Three musculoskeletal radiologists evaluated each ultrasound and MRI in a randomized and blinded fashion on 2 separate occasions...

INTRODUCTION: Leiomyoma is benign smooth-muscle tumor most commonly arising in the uterus, the gastrointestinal tract, and the skin. Leiomyomata are infrequently seen in the extremities and rarely seen in the bone. It is usually presented by a gradually increasing pain with nonspecific radiological findings, and could be a differential diagnosis for wide range of bone tumors. CASE PRESENTATION: We report a case of a 73-year-old Japanese female patient with a painful intraosseous leiomyoma involving the proximal tibia...

Patients with intramedullary signal intensity (SI) changes have a poor prognosis after surgical decompression in cervical compressive myelopathy (CCM); however, some patients show no clear relationship between the SI and postsurgical prognosis. This discrepancy may be because no comprehensive and proper quantitative evaluation exists to assess SI on magnetic resonance imaging (MRI). The purpose of this study was prospectively to evaluate the correlation between the clinical features, neurological outcome of patients with CCM, and the quantitative assessment of SI changes preoperatively and postoperatively, and the correlation with SI severity...

OBJECTIVE: Among pelvitrochanteric muscles, the internal obturator muscle is implicated in some pain projected at the buttock or perineum. Even though the pathophysiology is not completely understood, its responsibility is often held in clinical practice and in the literature due to effectiveness of botulinum toxin injections, constituting a therapeutic test. The objective is to enhance the couple ultrasound/EMG in difficult injections. MATERIAL/PATIENTS AND METHODS: Eighteen patients were treated in the physical medicine department (Besançon) from September 2015 to February 2016 for gluteal or perineal pain suspected to be related to abnormal spasm of the internal obturator muscle...
