Abstract Background: Modular stems in revision total hip arthroplasties allow diaphyseal fixation and optimal restoration of the architecture of the proximal femur. Several studies report metaphyseal implant breakage in the mid- to long-term and therefore a huge impact on survivorship. We aimed to evaluate a specific design of uncemented modular fluted tapered stems (MFT) to analyze survivorship and clinical and radiological outcomes.Methods: In a retrospective study, we identified 99 patients who had surgery using the same design of MFT implant between 2012 and 2014. Patients were mainly male in 53% and mean age was 73 years. Indications were 33 aseptic loosening, 24 periprosthetic fractures, 23 periprosthetic joint infection, 1 instability and 18 were complex primary arthroplasties. Survivorship, complications and clinical outcomes, were assessed. Mean follow-up was 5 years.Results: There was no implant breakage. At 5-year follow-up, the survivorship free of revision for aseptic loosening and free of revision for any reason of the femoral stem were 100% and 99%, respectively. At last follow-up, they were 94% and 81%, respectively. Six implants were revised. A mean stem subsidence of 6 mm was noted in 9 cases; 1 was revised for aseptic loosening. The Harris hip score was 89. The risk of revision was significantly higher for shorter diaphyseal implants (p=0.026).Conclusion: At mid-term follow-up of 5 years, the MFT studied reported an excellent survivorship and clinical outcomes with no specific complications. Unlike literature reports, no specific complications occurred with this design. Satisfying clinical outcomes and limited subsidence are consistent with previous reports though.Level of evidence: IV – Case series

Aim: The purpose of this study is to report the 20-year follow-up of a continuous series of 232 total hip arthroplasties (THAs) performed in patients aged less than 50 at the index surgery. Patients and methods: This is a retrospective monocentric study which reports the clinical, radiographical and survival results of 232 THAs performed with a custom cementless femoral stem in 212 patients evaluated at follow-up ranging from 14 to 27 years. Results: At the time of follow-up, the mean Harris Hip Score was 94.1 (range 48–100). The Hip disability and Osteoarthritis Outcome Score was >80 points in all 5 categories for 146 patients (68.9%). 18 hips (8.5%) showed radiographical femoral abnormalities. 23 hips (10.8%) underwent revision of the implants. 13 were isolated cup revisions. 3 more hips had bipolar revisions for aseptic loosening at 15, 20 and 21 years. Taking stem revision for aseptic loosening as an endpoint, survivorship was 96.8% at 20 years (95% confidence interval, 95.1–98.5; patients at risk 76) and 94.5% at 25 years (91.7–97.3; patients at risk 12). Conclusions: The results of this study confirm that THA using this custom-designed stem can provide excellent clinical and radiographical outcomes at a mean follow-up of 20 years in patients younger than 50. The individual 3D femoral stem and prosthetic neck has been able to restore extra- and intramedullary functional anatomy in this young and active cohort of patients.

Introduction: Birmingham Hip Resurfacing (BHR) implants may be combined with a conventional femoral stem to create a modular metal-on-metal total hip arthroplasty (BHR MoM THA). There is little outcome data regarding this construct. This study examines midterm outcomes of BHR MoM THA compared to oxidised zirconium total hip arthroplasty (THA). Methods: A retrospective institutional review identified all patients receiving BHR MoM THA between April 2005 and February 2011 and a matched control cohort of zirconium THA patients. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Harris Hip Score (HHS), and SF-12 Health status scores were obtained. Revisions and complications were collected from clinical records. Radiographs were assessed for evidence of component malposition, loosening, osteolysis, or heterotopic ossification. Results: 63 modular BHR MoM THA were identified in 61 patients (36 with BHR cups, 27 with R3 cups) and 63 zirconium THA in 58 matched controls. Mean follow-up was 58 months. 14 BHR MoM THA hips (22.2%) were revised (4 infections, 1 dislocation, 9 soft tissue reactions) compared to 3 (4.8%) zirconium THA (all infections). At latest follow-up, 18.4% of surviving BHR MoM THA hips were painful compared to 0.5% of zirconium THA controls ( p < 0.001). WOMAC, HHS, and SF-12 did not differ significantly between surviving members of the 2 groups. Discussion: BHR MoM THA demonstrated a high revision rate, largely for adverse local soft tissue reaction and pain. Among those not revised, many reported some residual pain despite similar quality of life measures to those who received zirconium THA.

Aseptic loosening in total hip arthroplasty can lead to proximal femoral periprosthetic bone loss. The non-cemented Wagner revision stem achieves primary fixation in the diaphysis. The purpose of this study is to evaluate the results after medium- to long-term follow-up of the Wagner prosthesis for revision of the femoral component for aseptic loosening in total hip arthroplasty with proximal femoral bone loss. We performed 53 femoral revisions for aseptic loosening with the non-cemented Wagner revision stem. Clinical assessment included a modified Harris Hip Score and a radiological evaluation. The mean follow-up was 65 months. The Harris Hip Score improved significantly (42.9 to 72.3). Radiological evaluation revealed 24.5% subsidence (>5 mm) in our population. Nine re-revisions were done, eight in the first post-operative year. The re-revisions were performed for progressive subsidence (five), recurrent dislocations (one), subsidence with low-grade infection (one), false route (one), and aseptic loosening after 75 months (one). The cumulative survival rate of the Wagner stem after 12 months was 85% and 76% after 75 months. A relatively high re-revision rate was observed during the first post-operative year. Analysis of these failures has shown that subsidence may be the result of insufficient primary stability. Adequate pre-operative planning and intra-operative radiological assistance is necessary for perfect primary stability and fixation of the Wagner stem. The re-revision incidence after the first 12 months is 0.45 per 100 implants per year. The prosthesis has good survival potential after proper introduction.

Introduction: This prospective study aims to evaluate the mid-term clinical and radiological performance of a new short, neck-preserving femoral stem in total hip arthroplasty (THA). Patients and methods: 178 consecutive patients (190 hips) underwent THA from November 2008 to July 2016. Mean follow-up is 62.4 months. Women make up 41% of the cohort at a mean age of 50 ± 4 years, with primary hip osteoarthritis as the main complaint. All patients underwent radiological evaluation using the modified Gruen method, and clinical assessment via the Harris Hip Score (HHS), preoperatively and at 1, 6, 12, 24, 60, 80 and 106 months post-op. Results: A mean HHS increase (from 50 ± 12 points preoperatively to 96 ± 4 at 62 months), together with painless articular improvement, was present at 6 months postoperatively indicating early functional recovery. Effective osteointegration and primary stability were present on radiographic analysis, without evidence of stress shielding or stem mal-positioning: subsidence amounting to <1 mm was present in 40% of implants immediately after surgery, with subsequent stabilisation within 6 months in all cases. Metaphyseal trabecular re-orientation in absence of symptomatic cortical hypertrophy or progressive radiolucency indicates physiological load transfer in the proximal femur. Stem-related revision surgery was necessary for 1.05% of all implants due to fracture and infection. No loosening, dislocations or mechanical failures were reported. Conclusions: All patients show excellent functional recovery and clinical outcomes at 62 months, demonstrating the role optimal primary stability and physiological joint reconstruction play in ensuring stable secondary fixation and long-term survival of a short, neck-preserving stem.

AbstractThe cementless, tapered wedge, short femoral stem implant is commonly used in direct anterior approach (DAA) total hip arthroplasty (THA). The lack of access and visualization, however, may increase the risk of perioperative fracture and early failure. Therefore, the current study examined perioperative complications and 2-year implant survivorship following DAA THA performed using a fracture table and short, tapered wedge femoral stem. A retrospective analysis was conducted on patients having undergone DAA THA with a cementless, tapered wedge, short femoral stem. Perioperative fractures were noted and survivorship was determined by the incidence of revision surgery within a minimum 2-year follow-up period. A total 366 consecutive patients (441 hips) were identified in the cohort. Four patients (6 hips; 1.4%) were lost to follow-up and three patients died from unrelated causes. Average follow-up time for the remaining 359 patients (435 hips) was 32.9 ± 10.2 months. There were no intraoperative factures but three perioperative fractures within two weeks. Aseptic loosening occurred in one stem at 13 months, resulting in a 99.1% survival rate with a mean survival time of 23.8 ± 0.1 months (95% confidence interval: 23.6–24.0 months). The use of a short, tapered wedge femoral stem and a fracture table for DAA THA resulted in 0.7% periprosthetic fractures and only one aseptic loosening within 2 years. These results suggest that proper femoral exposure with the use of a fracture table and a short, tapered wedge femoral stem does not appear to increase the risk of periprosthetic femoral fracture.

Objective: In this study we aimed to investigate the long-term clinical and radiological results, revision rates and causes, and the rate of implant survival in total hip arthroplasty performed using CLS® expansion cup and Spotorno® cementless femoral stem. Methods: Clinical results of total hip arthroplasty performed on 131 hips of 114 patients in Istanbul Training and Research Hospital between 1993 and 2003 were retrospectively evaluated according to the Harris Hip Score. Revision rates were determined and implant survival rates were identified using the Kaplan-Meier estimator. Results: Of the patients, 39 were males and 75 were females. The average age of the patients at surgery was 48.7±11.3 years. Patients were followed up for a mean period of 13.9±2.4 years. The mean Harris Hip Score was 34.35±6.09 preoperatively and 88.20±7.11 at the final follow-up (p<0.001). The Kaplan-Meier survivorship estimate for the cup at 13.9 years, taking revision for any reason as the end point was 95.6% (95% CI), while the 15th and 17th year survival rates were 90% and 85%, respectively. Conclusion: In total hip arthroplasty using a cementless expansive acetabular cup, a 95.6% survival rate is achieved after an average of 14 years, whereas the rate decreases to 85% after 17 years. Even if the incidence of cup breakage is reduced with proper implantation, particle disease and periacetabular osteolysis remains a problem for the long-term survival. doi: https://doi.org/10.12669/pjms.37.1.3089 How to cite this:Carkci E, Polat AE, Ozturkmen Y, Tuzuner T.

Abstract Background: To evaluate the clinical features and results of the revision total hip arthroplasties (THA) in patients with catastrophic failures and metallosis. Methods: Fifteen hips of 14 patients with catastrophic failure and metallosis in hip arthroplasties were evaluated. They were followed for at least 4.2 years after the revision THA. Clinical evaluation was performed using Harris hip score. Osteolysis, loosening or presence of metallosis was evaluated with standard radiographs. Metallosis was evaluated intraoperatively according to the metallosis severity classification. Results: The mean time from failure until revision surgery was 9.4 years. It was observed that in the primary THA, metal-on-ceramic (MoC), ceramic-on-ceramic (CoC) and metal-on-conventional polyethylene (MoCPE) bearings were used in 1, 3 and 11 hips, respectively. Grade III metallosis was observed in all patients during revision surgeries. The mean Harris hip score increased from 55 points before revision THA to 75 points at the final follow-up. In revision arthroplasty, MoCPE and CoC bearings were used in 13 and 2 hips, respectively. The femoral stem was replaced in 5 hips. All acetabular cups, except that of one hip, were revised. Conclusions: Revisions of THAs with catastrophic failures and metallosis are quite challenging. Routine follow-up of arthroplasty patients is beneficial to examine for osteolysis, loosening, and asymmetric wear.
