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 In this study, we described one unpublished technique of reverse sleeve of S-ROM to get through the complex situation.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.

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.

With improving healthcare, the number of Filipino octogenarians is increasing. Projected population of octogenarians as reported by the Philippine National Statistics Office will increase by 28% to 3,227,253 by year 2040 (from 2015: 912,817). This is a multicenter retrospective case series involving 24 patients (1 patient with surgery on 2 hips), with an average age at the time of surgery of 82 years old (range: 80-88 years old) who underwent total hip arthroplasty during the period 2007-2016. Indications for total hip arthroplasty included 12 cases of degenerative osteoarthritis, 8 cases of displaced femoral neck fractures, 4 cases of untreated femoral neck fractures, and 1 case of subtrochanteric fracture with hip arthritis. Of the 24 patients, 21 were females and 3 were males. Of the 25 hips, 19 were treated with cemented total hip, 5 with hybrid implants, and 1 with calcar replacing cemented femoral stem. Average follow-up was 36 months (range: 6-87 months). All patients were able to ambulate and return to premorbid function. There were no intraoperative or postoperative complications encountered. Revision rate was zero percent as of last follow-up. Clinical/functional results were assessed using the Harris Hip Scoring system. The results of this study affirm that primary total hip arthroplasty is a viable treatment option for active octogenarians with end-stage arthritis and hip fractures.

Purpose: Total hip arthroplasty (THA) is an available surgical option for failed acetabular fracture, previously managed by open reduction and internal fixation. This study aimed to report the postoperative outcomes of cementless THA in patients with this condition. Materials and Methods: Between November 2000 and September 2016, 25 consecutive cementless THAs for failed internal fixation after acetabular fractures with a minimum follow-up of 2 years were analyzed. The mean age at the time of surgery was 58 years (36–85 years), and the time elapsed between fracture and THA was 70 months (7–213 months). Clinical and radiologic evaluations were performed on all patients. Results: Clinically, the mean Harris hip score at the last follow-up was 88 points. Walking ability recovered to pre-injury status in 92% patients, and activities of daily living recovered in 96% patients. Radiographically, none of the acetabular cups showed evidence of migration and loosening during the mean follow-up of 50 months. All cases showed stable femoral stem fixation at the last follow-up. Dislocation occurred in three cases (12%). Conclusion: Outcomes of cementless THA after failed internal fixation for acetabular fractures were satisfactory. However, a relatively high incidence of postoperative dislocation is still a concern.

Primary Total Hip Arthroplasty

Aims: Modular-neck femoral implants are used to enable more variability in femoral neck version, offset and length. It has been reported that these implants carry a higher rate of revision. The aim of this review was to assess the overall and cause-specific revision rate of titanium-titanium alloy modular-neck implants in primary total hip arthroplasty (THA). Methods: A systematic review was conducted following PRISMA guidelines and utilising multiple databases. All results were screened for eligibility. Studies published from 2000 onwards, using a current-generation, titanium-titanium, modular-neck implant were included. Overall and cause-specific revision rates were analysed, comparing to fixed-neck prostheses where applicable. Results: 920 studies were screened. After applying exclusion criteria, 23 were assessed in full and 14 included. These consisted of 12 case series and 2 joint registry analyses. 21,841 patients underwent a modular-neck implant with a weighted mean follow-up of 5.7 years, mean age of 62.4 years, and average body mass index (BMI) of 28.4kg/m2. The overall revision rate was 3.95% and 2.98% for modular and fixed-neck prostheses, respectively. For studies with >5 years follow-up the mean revision rate was 3.08%. There was no difference in cause-specific revision rates by implant design. Mean improvement in Harris Hip Score was 41.9. Conclusions: At medium-term, revision rates for titanium-titanium primary modular-neck THA are acceptable. These prostheses are a sensible management option in patients with considerable anatomical hip deformity not amenable to correction with standard fixed-neck implants. Patients of male gender, high BMI and requiring prostheses with a larger neck, offset or head are at higher risk of implant failure.
