Boneloc versus Simplex Cement for Fixation of Femoral Components. An Interim Report of a Prospective Randomized Study of THRs with a 2,5 Year Mean Follow-Up Time

A prospective randomized study of femoral stem fixation comparing Boneloc and Simplex cements was carried out. A collarless double-tapered femoral component was used in all cases. The material consisted of 94 patients representing 97 THRs (3 bilateral cases). Their mean age was 76 years (range 58-88). Clinico-radiographic follow-ups were carried out after 3 months, 12 months and 2 to 3 years. The mean follow up time was 2.5 years. Clinically there was no difference between the groups. Radiolucencies at the bone-cement interface and metal-cement interface, cement cracks, and subsidence of the femoral component were compared. No significant differences could be proven between the fixation patterns of the bone cements during this short-term follow-up.

The Mean

The Mayo Conservative Hip femoral prosthesis has been designed to optimise proximal femoral loading as well as preserving proximal femoral bone stock. Between October 2003 and May 2006, 42 patients (49 hips) underwent total hip replacement (THR) using the Mayo Conservative Hip femoral component. The mean age at operation was 57.8 years (range 44 to 74) and the mean clinical follow up was 3.1 years (range 2.3 to 4.7 years). The aim of our study was to review the short term results of this unorthodox femoral component. We found that 18%° of stems were malaligned ≥ 5° and the prevalence of intra-operative femoral fracture was 4%. We feel this prosthesis is difficult to implant and has an unacceptable fracture rate.

Needle Revision

Background. To compare the efficacy of needle revision with 5-fluorouracil (5-FU) and mitomycin C (MMC) on dysfunctional filtration blebs shortly after trabeculectomy.Methods. It is a prospective randomized study comparing needle revision augmented with MMC or 5-FU for failed trabeculectomy blebs.Results. To date 71 patients (75 eyes) have been enrolled, 40 eyes in the MMC group and 35 in the 5-FU group. 68 patients (72 eyes) have completed 12-month follow-up, 38 eyes in the MMC group and 34 in the 5-FU group. The mean IOP before and that after needle revision in the MMC group were26.5±4.3 mmHg and11.3±3.4 mmHg, respectively (P<0.05), and in the 5-FU group were27.1±3.8 mmHg and10.9±3.4 mmHg, respectively (P<0.05). At 12-month follow-up, complete success rates were 57.5% for MMC group and 34.3% for 5-FU group (P=0.042; log-rank test) and 75% and 60% (P=0.145; log-rank test), respectively, for the qualified success. Complication rates between the two groups were not statistically different (P>0.05).Conclusions. Needle revision and subconjunctival MMC injection were more effective than needling and subconjunctival 5-FU injection for early dysfunctional filtration blebs after trabeculectomies.

Abstract Background Total hip arthroplasty is a successful treatment for hip osteoarthritis. Primary and secondary implant fixation is dependent on implant design and plays an important role in the longevity of an implant. In this study, we assessed the self-locking cementless MasterSL femoral stem. Materials and methods In this single-centre prospective study, 50 consecutive hips with the indication for total hip arthroplasty, who met the inclusion criteria, received the MasterSL stem from LIMA Corporate. Patients had pre- and post-operative clinical and radiological assessment and completed patient-reported outcome measures [Oxford Hip Score (OHS), Harris Hip Score (HHS) and Forgotten Joint Score (FJS)] at the 6-week and 6-, 12- and 24-month mark. Post-operative X-rays were assessed for osteointegration (Engh Score), alignment and subsidence. Results After 2 years, aseptic survival was 100%. One hip had to be explanted due to early deep infection and was excluded from the study. At 2 years, the patients reported a significant improved HHS and OHS of 95.3 ± 5.8 and 46.1 ± 3.6 (mean ± standard deviation), respectively, compared to preoperatively. The mean ± standard deviation for the FJS was 86.4 ± 18.7 with two-thirds of the patients reporting a score above 85. The mean Engh score is 15.1 ± 5.9 (mean ± standard deviation) with no patient scoring below 1 which suggests good osteointegration in all femoral stems. Conclusions The MasterSL femoral stem performed well in this short-term follow-up study, with high patient satisfaction and good signs of osteointegration. Long-term follow-up will be necessary to evaluate longevity. Level of evidence Level 3, Prospective cohort study. Trial registration The study was registered on the 30.03.2016 with Australia New Zealand Clinical Trials Registry (ACTRN12617000550303).
