Multicenter Study Clinical TrialResults of the Evora dual-mobility socket after a minimum follow-up of five years.
Dislocation is a well-known complication of total hip arthroplasty. The risk can be reduced to one or two cases per thousand using a dual-mobility cup. The survival rate achieved with the Bousquet implant is 95% at 10 years. The complications with this implant are early mobilization and inguinal pain. An overly-large cup and insufficient primary and secondary fixation can be implicated. The design of the original implant was later modified to limit these early complications. The purpose of this study was to check the validity of these design changes. ⋯ Changing the design of the implant to modify its volume, material and primary fixation has eliminated the early mobilizations and inguinal pain described for the original Bousquet cup. These options have not had any deleterious effect on prosthesis stability. The question of long-term wear remains an important problem and requires optimization: a neck as thin as possible, optimized surfacing, elimination of laser marks, extraction leads and head skirts.

Review Randomized Controlled Trial Clinical Trial[Lumbar facet joint syndrome. Significance of non-organic signs. A randomized placebo-controlled clinical study].
One hundred and nine patients with chronic (greater than 3 months) unilateral low back pain had less than or equal to 2/5 or greater than or equal to 3/5 inappropriate signs (IAS) in 65 and 44 cases, respectively. The patients were randomized in three therapy groups: cortison and local anaesthetic injected intra-articularly into two facet joints (28 patients), the same mixture injected pericapsularly around two facet joints as well (39 patients) and injection of physiologic sodium hydrochloride intra-articularly into two facet joints (42 patients). The effect of the treatment was evaluated within an hour, two and six weeks after the treatment with work status, pain scale, disability score and movements of the lumbar spine. ⋯ Identification of these patients may also prevent the doctor from a burn-out syndrome after many failed treatments. This study also shows that if a biological effect of a treatment is to be studied the patients with multiple IAS should be excluded from the material. There was no difference in the results when either intra-articular or pericapsular cortisone and local anaesthetic or saline intra-articularly was used.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports[Paraplegia after interlaminar epidural steroid injection: a case report].
We report the first case of paraplegia observed after epidural steroid injection in the upper spine. The patient was a 42-year-old male who underwent surgery two years earlier for stenosis of the lumbar spine from L2 to the sacrum leading to early manifestations of an equina cauda syndrome. This first operation provided satisfactory function with complete resolution of the objective neurological symptoms. ⋯ The patient's neurological status remained unchanged and four days later the T2 MRI sequence revealed a high-intensity intramedullar signal in the cone. The diagnosis of ischemia of the medullary cone was retained, hypothetically by injury to the dominant radiculomedullary artery via an undetermined mechanism. This complication has been previously described after upper foraminal steroid injections but not after intralaminar epidural steroid injection.

ReviewTreatment of osteochondral defects of the talus.
This review article provides a current concepts overview of osteochondral defects of the talus, with special emphasis on treatment options, their indications and future developments. Osteochondral defects of the talar dome are mostly caused by a traumatic event. They may lead to deep ankle pain on weight-bearing, prolonged swelling, diminished range of motion and synovitis. ⋯ For large cystic talar lesions, retrograde drilling combined with a bone graft is an important alternative. In adolescents or in (sub)acute situations, in which the fragment is 15 mm or larger, fixation of the fragment is preferred. Osteochondral autograft transfer and autologous chondrocyte implantation (ACI), with or without a cancellous bone graft, are recommended for secondary cases as well as large lesions.
