Abstract Purpose The cementless implantation of hip replacement cups may be performed with and without the additional use of acetabular screws. If the surgeon uses screws or not depends on variable factors. In general, the use of screws is intended to increase the primary stability of the cup. Whether screws increase the initial stability of the cup construct, or even reduce it in part, is the subject of considerable debate in the literature. It is also unclear whether the additional screws lead to increased wear or increased periacetabular osteolysis over the long-term course. Methods Two hundred eleven patients from a previous study with a minimum follow-up of 10.7 years were included. Of these, 68 patients with 82 total hip arthroplasties (THA) were given clinical and radiological follow-up examinations. Of these, 52 had been fitted without screws and 30 with screws. On the basis of radiographs, annual wear and osteolysis were quantified. The clinical results were recorded by means of VAS, HHS, and WOMAC scores. Results Significantly more periacetabular osteolysis was found if additive acetabular screws had been used. No difference was found in relation to the volumetric wear per year. Likewise, no difference was found with regard to the clinical scores. Conclusions The use of additive acetabular screws leads to increased osteolysis in the periacetabular bone stock. Insofar as the primary stability of the cementless cup construct allows it, no additional acetabular screws should be used.

We evaluated the effect of local infiltration of NSAIDs on prosthetic fixation at mid- to long-term follow-up of total hip arthroplasties. Intra-articular local NSAID (ketorolac) was injected into hip joints and surrounding tissues intraoperatively and postoperatively as a part of multimodal pain management protocol. Clinical and radiographic evaluation was performed for any evidence of component loosening or failure and clinical outcomes in 100 total hip joint arthroplasties with a mean follow-up of 7.3 years (4.9 to 11 yrs). Radiographic analysis at the most recent follow-up showed no evidence of loosening, subsidence, or migration and no evidence of impending failure. Clinical outcomes showed improved Harris hip scores. Intra-articular NSAID used in the intraoperative/postoperative period in hip arthroplasty showed no evidence of prosthetic loosening at mid- to long-term follow-up.

Introduction: The interpretation of clinical results of dental implant supported prosthesis treatment is very crucial to be able to make a comparison between different implant systems and treatment options and furthermore to benefit the experiences of the other clinicians. However, the clinical outcomes of these studies should be reported in an objective way and be independent from the system used and also be prepared in accordance with certain criteria and standards that have been accepted scientifically world-wide for being reliable and describing long-term results. Aim: Three-hundred and eighty-two consecutive NTA implants were performed on ninety-nine patients. The implants used in 2016 and the constructed restorations were retrospectively analyzed. In addition, the effect of the experience of clinician was evaluated related with the success of the implant therapy. Materials and Method: This retrospective study was conducted in the Department of Prosthodontics Süleyman Demirel University. Three-hundred and eighty-two consecutive NTA implants were performed on ninety-nine patients. The implants used in 2016 and the constructed restorations were retrospectively analyzed. Results: The implants were followed for at least 2 years. In total, 239 implants were inserted. It was found in 143 mandibles. Prosthetic restorations were determined to be partial prosthetics (219), single crown (81) and overdenture prosthetics (64). During the evaluation period, 6 implants failed before prosthetic treatment, ten decementations, six retentive screw loosening and five porcelain chipping were detected. Discussion and Conclusions: The early results of our study are consistent with the results of other studies. However, long-term follow-up is required for more accurate assessments.

Abstract Purrpose Metal-on-metal (MoM) total hip arthroplasty (THA) has been a subject of recent discussion and concern due to the early failures caused by local and systemic adverse reactions related to specific designs. The aim of this study is to analyze the outcomes and survival rates of a single brand of MoM implants implanted in a consecutive series of patients at a single institution. Methods Between 2007 and 2012, 116 (118 hips) patients were evaluated at a mean follow-up of 6.6 years after primary THA. The diagnosis leading to surgery was osteoarthritis (80 patients) and proximal femoral fracture (36 patients). A single design of THA was implanted. All patients were evaluated before surgery and postoperatively at 1, 3, 6, and 12 months by clinical scores and radiographic studies. The data analysis was made using Student's t-test. Results The minimum follow-up was of 4 years, with a mean follow-up of 6.6 years. Two aseptic loosenings of the acetabular component were recorded (one per group), which were not associated with local or systemic complications related to metal ion release. Both were revised by an isolated acetabular cup substitution with metal-on-polyethylene couplings. Nonprogressive radiolucency lines < 2 mm in zone 2 were observed in other six patients around the acetabular component without clinical manifestation (four in the arthritis group and two in the fracture group). Postoperative Harris Hip Score and SF-36 (36-Item Short Form Survey) score improved in both groups. Conclusion Despite several MoM implants showing early complications and failures, a specific MoM design may be associated with good clinical results at a mid- to long-term follow-up. Level of Evidence This is a therapeutic case series, Level 4 study.
