Randomized Controlled TrialThe effect of meperidine-impregnated autogenous free fat grafts on postoperative pain management in lumbar disc surgery.
Prospective, randomized, double-blind clinical study. ⋯ In this study, we helped patients, who underwent 1-level, first-time lumbar microdiscectomy have a postoperative pain-free and comfortable period by using epidural meperidine-impregnated AFFGs.

Randomized Controlled Trial Comparative StudyCervical kinematics after fusion and bryan disc arthroplasty.
Disc arthroplasty has been shown to provide short-term clinical results that are comparable with those attained with traditional anterior cervical discectomy and fusion. One proposed benefit of arthroplasty is the ability to prevent or delay adjacent level operations by retaining motion at the target level and eliminating abnormal adjacent activity. This paper compares motion parameters for single-level anterior cervical discectomy and fusion and disc replacement patients at the index level and adjacent segments. ⋯ The Bryan disc may delay adjacent level degeneration by preserving preoperative kinematics at adjacent levels.

Randomized Controlled Trial Multicenter StudyClinical outcomes of BRYAN cervical disc arthroplasty: a prospective, randomized, controlled, multicenter trial with 24-month follow-up.
Prospective, randomized, 3-center, clinical trial. ⋯ At 24 months, cervical arthroplasty with the BRYAN Cervical Disc Prosthesis compares favorably with ACDF as defined by standard outcomes scores.

Randomized Controlled Trial Multicenter StudyAnterior cervical microdiscectomy with or without fusion.
Anterior cervical microdiscectomy (ACD) is commonly applied in the surgical treatment of cervical disc herniation. However, following discectomy procedure to perform a fusion process is still controversial. Therefore, a controlled, multicentric, prospective, randomized study was designed. ⋯ ACD technique offers satisfactory outcome regardless of whether fusion process is applied or not. Fusion with semirigid plate offers an advantage at operated level in immediate postoperative period in regard of disc height and neural foramen height. However, semirigid anterior plates by definition do not stop subsidence and the advantage that is offered by this technique is not persistent. On the other hand, to apply fusion process with semirigid plate system offers significantly less narrowing in disc height compared with simple ACD technique.

Randomized Controlled Trial Multicenter StudyMeasurement of lumbar lordosis: inter-rater reliability, minimum detectable change and longitudinal variation.
Repeated measures design to examine reliability and longitudinal variation of lumbar lordosis measurement. ⋯ This study demonstrates that the 4-line Cobb method can be a highly reliable and precise method for measuring lumbar lordosis if standardized procedures are used. The Cobb method has an MDC that is appropriate for clinical use. Also, there is minimal longitudinal variation in lordosis measurements over a 2-year period.
