Abstract Background The aim of this retrospective study was to document the long-term clinical efficacy of a surgical-prosthetic technique (the flat one-bridge technique) involving the immediate restoration of both postextraction and nonpostextraction implants supporting full-arch restorations. Methods Implants were placed by adapting the axis to the available bone. Flat definitive abutments were connected during surgery and never disconnected to compensate for eventual implant disparallelism. Bone grafting was performed when needed. The patients received a screw-retained provisional restoration within 48 h of surgery and a final screw-retained prosthesis within 1 year. Results Sixty-six patients received 494 implants distributed in 75 prostheses. The median follow-up was 86 months (range 82–168 months). Only three implants had failed at the last follow-up. Implant survival was 99.6%. Conclusion The flat one-bridge prosthetic protocol is a viable procedure with excellent long-term outcomes. No difference in clinical success could be observed between postextractive and nonpostextractive implants.

Introduction: The purpose of the current study was to investigate the periprocedural and long-term outcomes of stent implantation for de novo subclavian artery (SCA) disease. Material and Methods: We retrospectively investigated consecutive patients with de novo SCA lesions undergoing elective endovascular therapy procedures at our center between April 2004 and September 2015. All patients were included in the analyses of periprocedural outcomes, including procedural and clinical success. Subsequently, patients who completed the clinical follow-up and were assessed with brachial systolic pressure differences between the diseased and the contralateral arms, or angiographic stenosis, after stent implantation with procedural success were included in the analyses of long-term outcomes, including primary patency. Results: There were 62 patients (median 71.0 years, interquartile range 65.3-76.0 years; 45 men) with 62 de novo SCA lesions included in the analyses of periprocedural outcomes. There were 46 stenoses (74.2%) and 16 occlusions (25.8%). Our results indicated high procedural success rates for overall (95.2%), stenotic (97.8%), and occlusive (87.5%) lesions. Similarly, high clinical success rates were observed for overall (91.9%), stenotic (93.5%), and occlusive (87.5%) lesions. The median follow-up time was 6.0 years (interquartile range, 2.6-8.3 years). There were 48 patients with 48 de novo SCA lesions included in the analyses of long-term outcomes. Primary patency estimates were 97.7% (1 year), 97.7% (3 years), 93.1% (5 years), and 87.6% (7 years). Also, we observed a high estimate for freedom from reintervention for the target vessel (93.8%). Conclusion: Stent implantation for de novo SCA disease can be performed successfully and safely with favorable periprocedural and long-term outcomes.

Background Post-traumatic arthritis of the hip is a degenerative condition that commonly affects young patients. In this study, we evaluate long-term implant survival and patient-reported outcomes after primary total hip arthroplasty (THA) in patients aged 35 or younger with post-traumatic arthritis of the hip. Methods We conducted a retrospective study with follow-up. A chart review was performed to identify young patients with post-traumatic arthritis of the hip treated with primary THA. Follow-up surveys were conducted to determine implant survival and patient-reported outcomes. Implant survival was assessed using Kaplan-Meier survival analysis, and patient outcomes were determined using the hip disability and osteoarthritis outcome score (HOOS). Results We studied 42 patient s (44 THAs) with a mean time to follow-up of 14 years. The 10-year implant survival rate was 87% and 20-year implant survival rate was 41%. Implant survival did not differ based on patient age, gender, implant type, bearing surface, or use of cement for implant fixation (p>0.05). The mean HOOS scores at follow-up were 87 for pain, 85 for symptoms, 89 for ADLs, and 76 for sports. HOOS scores were significantly worse in patients that had undergone revision THA (p<0.05). Conclusions Young patients with post-traumatic arthritis of the hip have good long-term outcomes after THA. However, revision THA is predictive of worse long-term outcomes.

Objectives: Dental implants are a prominent scientific breakthrough and are frequently applied for replacement of the missing teeth. From the clinicians’ point of view, long-term studies are essential to find out the predictability of dental implant systems. Materials and Methods: In this retrospective study, 1,626 patients who received 4,389 Dyna implants in a private office between 2013-2019 were evaluated. All statistical analyses were performed using SPSS 25 for Windows. P values less than 0.1 were considered significant for regression analysis. Results: Dyna implantts (4389) placed from 2013 to 2019 were evaluated in this study. One-hundred and thirty-three (3.03%) implants failed during the healing period or recall visits. Eighty-nine implants (2.03%) failed immediately and 44 (1%) failed after 3 months. Conclusion: The present study showed that the Dyna dental implant system had high implant survival, and it had all the survival criteria similar to world-class dental implant systems.

Background: National and international guidelines lack consistency on how to screen metal-on-metal (MoM) hip arthroplasty patients for adverse reactions to metal debris (ARMD). Long-term outcomes of MoM hip arthroplasty are scarce, hindering further development of such guidelines. We present the clinical, radiological and ARMD status of 158 cases of hip resurfacing with >10 years follow-up. Methods: A prospective analysis of a cohort of 298 consecutive hip resurfacing procedures was performed at a single institution. All patients underwent MARS-MRI scanning for pseudotumour screening at least once, regardless of symptoms. Implant survival and reasons for revision were analysed for all patients. Clinical, radiological and MARS-MRI results were analysed for 158 unrevised procedures with >10 years follow-up. Results: The implant survival was 85.9% at 14.5 years (95% CI, 81.9–90.6) with revision for all causes as endpoint and 92.3% with MoM disease-related revisions excluded (95% CI, 88.2–95.0). Of the 158 cases with >10 years follow-up, 1 had elevated metal ion levels, 29 had a stable C1 pseudotumour and 6 a stable C2 pseudotumour. All pseudotumours were observed within 3 years after initiating our intensified ARMD screening (2011), with no new pseudotumours observed after that period. Conclusions: We suggest that follow-up of MoM hip resurfacing patients beyond 10 years after surgery can be done with large intervals (i.e. every 5 years), and only earlier if a patient becomes symptomatic.

Implant Dentistry

Today, clinicians have a variety of treatment modalities available to address the increasing number of implant procedures performed each year. Single-stage implant surgery is now commonly used in implant dentistry. With patients' demands for immediate restoration, the utilization of 1-piece implants is gaining acceptance. This article reports the results of tapered 1-piece implants (Zimmer Biomet) placed in a single practice over a 10-year period. A total of 33 1-piece dental implants were placed in 24 patients and provisionally restored out of occlusion at the time of surgery. All 33 implants were definitively restored with ceramometal crowns after 3 months of provisionalization. Implant survival and success rates were 100% after 2.6–10 years of follow-up. Only 1 minor complication of crestal bone remodeling occurred among the 33 implants placed. Adequately stabilized tapered 1-piece implants can be successfully restored out of occlusion at the time of implant placement and definitively loaded in occlusion 3 months without adversely affecting function or esthetics. Additional long-term controlled studies are recommended to further understand these findings.

Abstract Background Gastro-oesophageal reflux disease (GORD) can have a significant effect on patients quality of life, especially in sever cases. Laparoscopic Antireflux surgery is the most common approach which offers promising long-term outcomes. However, Failure of antireflux procedures are reported in 5% to 10% of the patients who might require a redo-antireflux surgery (Redo-ARS). This study aims to assess the long-term outcomes of Redo-Antireflux surgeries regarding symptoms control and patient satisfaction. Methods Retrospective study for patients who underwent Redo-ARS with a single consultant in the south of England. Follow up was done using The GORD Health-Related Quality-of-Life (GORD-HRQL) scale and patients reported their scores before and after the redo-surgery.   Exclusion criteria included follow up less than one year and failure of contacting the patient. Results All patients who underwent Redo-ARS between 2009-2019 were enlisted and 18 -out of the identified 22- were included in the study. Overall, There was a significant decrease in heartburn severity after the redo operation with a median reported severity of 4.5 preoperatively which decreased to 2 after the operation with a P value of 0.00062. This was observed in assessment of heartburn symptoms severity during sleep, laying flat, standing and after meals which all showed improvement after the operation with P values &lt;0.005. There was no statistically significant improvement of dysphagia, odynophagia or bloating. The median follow up was 5 years. Conclusions Redo laparoscopic antireflux operations are technically challenging, however, significant heartburn symptoms control is feasible. Further evaluation of types of surgeries and patient selection can guide decisions regarding further management and guidelines.

Aims The aim of this study was to present the long-term surgical outcomes, complications, implant survival, and causes of implant failure in patients treated with the modified Harrington procedure using antegrade large diameter pins. Patients and Methods A cohort of 50 consecutive patients who underwent the modified Harrington procedure for periacetabular metastasis or haematological malignancy between January 1996 and April 2018 were studied. The median follow-up time for all survivors was 3.2 years (interquartile range 0.9 to 7.6 years). Results The five-year overall survival rate was 33% for all the patients. However, implant survival rates were 100% and 46% at five and ten years, respectively. Eight patients survived beyond five years. There was no immediate perioperative mortality or complications. A total of 15 late complications occurred in 11 patients (22%). Five patients (10%) required further surgery to treat complications. The most frequent complication was pin breakage without evidence of acetabular loosening (6%). Two patients (4%) underwent revision for aseptic loosening at 6.5 and 8.9 years after surgery. Ambulatory status and pain level were improved in 83% and 89%, respectively. Conclusion The modified Harrington procedure for acetabular destruction has low complication rates, good functional outcome, and improved pain relief in selected patients Cite this article: Bone Joint J 2019;101-B:1557–1562
