Randomized Controlled Trial Comparative Study[Comparative study of short-term results between total artificial disc prosthesis and anterior lumbar interbody fusion].
The purpose of this study was to examine short-term clinical results with a lumbar disc prosthesis in comparison with anterior interbody fusion for the treatment of chronic low-back pain resulting from disc degeneration. ⋯ The lumbar disc prosthesis offers a possible alternative to lumbar arthrodesis for the treatment of severe disc degeneration at one level in the young subject. It has been found to enable more rapid and superior functional results.

Randomized Controlled Trial Comparative Study[Pertrochanteric fractures: a randomized prospective study comparing dynamic screw plate and intramedullary fixation].
The objective of this study was to compare the dynamic hip screw (Synthes) and intramedullary fixation (Targon PF, Aesculap) for the treatment of pertrochanteric fractures in terms of stability, complications and cost effectiveness. ⋯ Data in the literature report an advantage for intramedullary nailing, particularly a mechanical advantage, for the treatment of pertrochanteric fractures. Our findings show that good results are obtained with the screw-plate fixation using the DHS with less blood loss and at a lower cost.

Randomized Controlled Trial Comparative Study Clinical Trial[A prospective randomized study of wound drainage versus non-drainage in primary total hip or knee arthroplasty].
Drainage of the operative wound following total hip or knee replacement (THR, TKR) is usually performed to avoid hematoma formation. A certain amount of blood is lost through the drain. The necessity of wound drainage has been questioned, with a view towards blood saving, although most surgeons have not abandoned drainage for fear of local complications. A prospective randomized study was undertaken to compare drainage and non-drainage following THR/TKR in terms of blood-saving and local complications. ⋯ Following primary hip or knee arthroplasty, the use of wound drainage did not lead to increased blood loss, and non-drainage did not lead to significant wound healing problems but did not reduce blood loss and transfusion requirements. It was even associated, following TKR, with greater blood loss and transfusion. Such data may therefore be used to support drainage as well as non-drainage following THR or TKR. Avoiding drainage may be interesting in terms of cost, but the benefit is marginal; it also eliminates one possible source of retrograde wound infection. Systematic wound drainage following THR or TKR is essentially a tradition. This study shows that it can safely be dispensed with in a number of cases.

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)
