Abstract Background: Trochanter valgus deformity (TVD) is a rare condition of total hip arthroplasty (THA). Femoral osteotomy could be required in correcting the deformity to implant femoral stem in severe TVD. In this study, we described one unpublished technique of reverse sleeve of S-ROM to get through the complex situation. This study aimed to summarize and evaluate its technical challenges, safety and effectiveness.Methods: From January 2006 to December 2014, we enrolled patients whose sleeves were implanted towards the great trochanter in THA with TVD. Their demographics, perioperative and postoperative information were recorded. To explore its indication, we measured and analyzed the ratio of greater trochanter/lesser trochanter (G/L ratio) and trochanter valgus angle (TVA).Results: Twelve patients (1 male and 11 female, average age 42.30±10.23) had mean follow-up of 6 years. Among them, only two patients had intraoperative femoral fracture. The survivorship of femoral prosthesis was 100%. The Harris hip score (HHS) increased from preoperative 34.31±14.43 to postoperative 84.12±11.33. All patients’ G/L ratio were larger than 1.50.Conclusions: The reverse sleeve of S-ROM was a reliable method for the patients with severe TVD, which brought satisfying clinical outcomes in mid-term follow-up.Keywords: cementless modular stem; reverse sleeve; total hip arthroplasty; trochanter valgus deformity.

Abstract Background: Ttrochanter valgus deformity (TVD) is a rare condition of total hip arthroplasty (THA). The femoral osteotomy might be required to correct the deformity to implant the femoral stem in severe TVD. In this study, we described one unpublished technique of reverse sleeve of S-ROM to get through the complex situation. The aim of this study was to summarize the technical challenges of this special sleeve-implanting method and evaluate its effectiveness and safety. Methods: From January 2006 to December 2014, the patients who had the reverse sleeve to solve the TVD in THA were enrolled. Their demographics, perioperative and postoperative information were recorded. To explore its indication, we measured and analyzed the ratio of greater trochanter/lesser trochanter (G/L ratio) and trochanter valgus angle (TVA). Results: Twelve patients (1 male and 11 female, average age 42.30±10.23) who had the complete clinical data were analyzed. The survivorship of femoral prosthesis were 100% with mean follow-up of 6 years. No other complications were found, except for two patients with intraoperative fracture of femur. The Harris hip score (HHS) increased from preoperative 34.31±14.43 to postoperative 84.12±11.33. All patients’ G/L ratio were larger than1.50. Conclusions: The reverse sleeve of S-ROM was a simple and reliable method for patients with severe TVD, which brought satisfying clinical outcomes in mid-term follow-up. When G/L ratio is larger than 1.50, surgeons should consider this special surgical technique. Keywords: cementless modular stem; reverse sleeve; total hip arthroplasty; trochanter valgus deformity.

Superior Approach

This study aims to establish the midterm safety and performance for the direct superior approach to minimally invasive surgery total hip arthroplasty (MIS-THA). We used a unicentric, single-surgeon, retrospective, consecutive case series analysis of the first 40 patients who received primary unilateral direct superior MIS-THA. Special attention was given to functional recovery by measuring Harris Hip Score (HHS) and timed-up-and-go (TUG) with a mean follow up of 2.2 ± 0.4 years. A radiologic evaluation was performed. HHS and TUG improved significantly at three months and one year (p < 0.001). All components were placed within the Lewinnek safe zone with no change position or signs of loosening at two years. With a minimum of two years of follow up, the direct superior approach appears to be safe without any obvious or consistent postoperative complications—clinically or radiographically—with excellent functional recovery. Additionally, our subgroup analysis supported no late learning curve effect.

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.

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.

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.

This study aimed to report the outcome of total hip arthroplasty (THA) with an extensive hydroxyapatite (HA) coating for the fixation of a tapered femoral stem (Corail) in patients aged 60 or younger than sixty years with stage IV, V và VI osteonecrosis of femoral head. Subject and method: Descriptive prospective research of ninety osteonecrotic hips in ninety patients were available for clinical and radiographic analyses at minimum follow-up of 5 years. Results and Conclusion: The mean Harris hip score improved from 43.74 ± 9,25points preoperatively to 96.67 ± 3.82points at final follow-up. Seventy-four (100%) hips demonstrated stable bone ingrowth. No hips showed acetabular or femoral osteolysis radiolucency and loosening, or required revision for aseptic loosening. We believe that cementless THA with a Corail stem is a promising procedure for patients with osteonecrosis of the femoral head.
