Magnetic resonance imaging in patellar lateral femoral friction syndrome (PLFFS): prospective case-control study.

Objectives: To describe morphologic abnormalities and signs of patellar lateral femoral friction syndrome (PLFFS) detected by magnetic resonance imaging (MRI).

Materials And Methods: Prospective study of 56 knees (21 patients and 30 controls) studied by 3Tesla MRI. Comparative analysis of clinical data, quantitative and qualitative imaging criteria in a population of patients with anterior knee pain associated with an abnormal MRI signal along the lateral alar folds of the infrapatellar fat pad, a characteristic sign of PLFFS, and a control population with no anterior knee pain or abnormal signal from the infrapatellar fat pad.

Suture anchor reinsertion of distal biceps rupture: clinical results and radiological assessment of tendon healing.

Introduction: The present study consisted in a clinical follow-up of patients with distal rupture of the biceps brachii tendon managed by suture anchor reinsertion to the radial tuberosity. Tendon apposition on the cortical bone is the least resistant reinsertion technique according to biomechanical studies. A parallel radiological (X-ray and MRI) study was therefore performed to assess the exact quality of tendon healing and its correlation to clinical results.

Anatomical and radiological study applied to distal radius surgery.

Purpose: The purpose of this study was to determine, during anterior plating of the distal radius, the length of a screw above which there is a risk for the extensor tendons and the optimal shape of an anterior plate. It was also to determine the projection of the axis of the distal third of the radius on the distal articular surface in case of wrist arthroplasty in order to simplify the procedure.

Methods: We studied 74 dry radii from adult cadavers.

[Rotator cuff tears: value of 3.0T MRI].

Purpose: To demonstrate the value of 3.0T MR imaging for the detection of rotator cuff tendon tears and surgical planning by correlating imaging findings to surgical findings. Materials and methods.

[Evaluation of the efficacy of CT-guided epidural and transforaminal steroid injections in patients with diskogenic radiculopathy].

Purpose: To evaluate the efficacy of CT-guided epidural and transforaminal steroid injections in patients with diskogenic radiculopathy.

Materials And Methods: Seventy patients underwent CT guided injections after failure of medical management. Only patients with minimal degenerative changes and diskogenic monoradicular symptoms were treated.

[Combined bipolar radiofrequency and cementoplasty of bone metastases].

Bone metastases are the most common cause of pain in cancer patients. Pain management in cancer patients, often revealing the disease and always present at advanced stages, is an important and difficult task. Pain is not always properly controlled by high doses of specific medication, radiation therapy or chemotherapy.

[Ganglion cyst rupture in the retro-femoral fat: a report of two cases].

Ganglion cysts are ubiquitous cystic lesions without synovial wall and inconstant communication with the articular cavity. The later must nonetheless always be carefully looked for. We report two cases of ganglion cyst rupture in the retrofemoral fat simulating phlebitis with thigh cellulitis.

[Pain management in bone metastasis of pulmonary origin: new interventional and metabolic techniques].

Invasion of bone by a metastatic lesion is the most common cause of pain in cancer patients. Pain management in these patients is an important and difficult task. The pain is not always properly controlled by high doses of specific medication, radiation therapy or chemotherapy.

[True isolated atherosclerotic aneurysm of the axillary artery].

The true atherosclerotic aneurysm of the axillary artery is a rare condition. It either presents as a pulsatile axillary mass or arterial emboli in the hand and fingers. We report the case of a 70-year-old man with a 5 cm aneurysm of the axillary artery presenting with embolic disease to the hand.

[Fluid-fluid level in an intra-osseous ganglion cyst of the talus].

The author report a very rare case of fluid-fluid level in an intra-osseous ganglion cyst of the talus that was detected on CT and MR imaging. Pre-operative diagnosis was suggested by the presence of a communication between the talo-cuboid joint and the cyst, as shown at MR Arthrography.

Percutaneous ethanol injection into parathyroid adenomas: mid- and long-term results.

The aim of this study was to evaluate mid- and long-term results of ultrasonically guided ethanol injection into parathyroid adenomas. From 1988 to 1996, 27 patients (mean age 77 +/- 13 years) were treated for parathyroid adenomas by percutaneous ethanol injection. The survey included clinical information, plasma calcium, phosphorus and PTH (1-84) evaluation.

[Subcutaneous trochanteric bursitis: an unrecognized cause of peritrochanteric pain revealed by imaging].

We present four cases of subcutanea trochanterica bursitis (one involving both sides). The bursitis was acute and inflammatory in two cases, chronic and microtraumatic in one, asymptomatic in one and septic in the last case. The acutely inflamed bursa may contain a blood effusion increasing the pain.

[Comparison between iopamidol and ioxaglate in digital arteriography of the lower limbs].

This prospective study concerning 100 subtraction angiographies of the lower limbs compared two iodine concentrations of iopamidol (300 and 370 mg l/l) and ioxaglate (320 and 350 mg l/l). More pain and movements disturbed the subtraction with iopamidol 370 in comparison with ionic contrast media (p < 0.005).

[Spontaneous disappearance of herniation pit on the femoral neck].

The authors present a case of a 39 years old patient who had a herniation pit of the left femoral neck, 5 years ago. This lesion disappeared spontaneously. To our knowledge, no report of healing of a herniation pit has been previously described.

[MRI of the semicircular canals in cranio-facial asymmetries and craniomandibular syndrome].

The cranio-mandibular syndrome (CMS) is often secondary to an cranio-facial asymmetry (CFA); it associate a painful masticatory dysfunction syndrome with functional and aching clinical signs in relation with a functional torticollis required for oculo-labyrinthal equilibration maintenance. Our anatomical and functional MRI protocol uses tridimensional study of semi-circular canals (SCC) up relation to the medial cerebral axis (MCA), and permit to measure precisely these CFA and propose, with a multispecialist approach, an adapted treatment of the SCM. Application of MRI to SCC asymmetry looks to its future use for spatial intracranial referencial of cerebral structures.

[Percutaneous angioscopy and angioplasty in the treatment of arteriopathies of the lower limbs].

Since 1987, the authors have routinely combined angioscopy with angioplasty of peripheral arteries. In a series of 251 angioplasties carried out in 191 patients, angioscopy was found to be more specific and more sensitive than arterial angiography in the etiological diagnosis of arterial stenoses and/or obstructions. Angioscopic findings modified the angioplasty procedure in 29% of cases.

[Chondrosarcoma of the femur neck simulating a normal variant. A difficult diagnostic pitfall].

We report a case of chondrosarcoma of the femoral neck wrongly considered as a normal variant during a long time due to the initial aspect on the plain films and its location. Precise radiological criteria must allow the differential diagnosis and will be detailed.

[Lipoma of the spermatic cord. Description of a case and review of the literature].

The authors analyse a case of fibrolipoma of the spermatic cord. It is the most common entity in the non testicular tumors. Ultrasound imaging has proven his utility.

[Subperiosteal chondroma. Diagnostic contribution of x-ray computed tomography. Apropos of 2 cases].

Results of CT scan exploration are reported in two cases of subperiosteal chondroma, one in a 4 year old child affecting the anterior tibial tuberosity the other in a 9 year old child involving the upper end of humerus. Data from CT scan imaging were undoubtedly superior to those of conventional radiography and appear to be characteristic of this benign cartilaginous tumor, greatly facilitating correlation between clinical, radiological and pathologic findings. The scanner should allow certain situations to be dedramatized and the surgical attitude adapted when the functional prognosis is involved.

[Dorsal spinal cord compression caused by vertebral subperiosteal chondroma. Apropos of 2 cases].

The authors report 2 cases of vertebral subperiosteal chondroma causing thoracic spinal cord compression. Total excision of this benign cartilaginous neoplasm is usually sufficient treatment.

[Bilateral traumatic carotid-cavernous fistula treated using an inflatable and detachable balloon].

The authors report a case of traumatic bilateral carotid-cavernous fistula successfully treated by inflatable and detachable balloon.
