“…Lastly, we did not measure for inter-and intraobserver variability of radiographic measurement but instead agreed on findings through consensus. In a review of the literature, we found similar studies referencing Johnston et al [22] and Engh et al [14] when addressing radiographic evaluation; however, no statistical analysis of reliability was performed in these studies [1,12,30,31,37]. Osteoporotic bone exhibits diminished cellular and structural characteristics, potentially compromising ingrowth/ outgrowth of the implant.…”

Background Limitations of conventional uncemented femoral stems persist, including proximal-distal mismatch, nonideal load transfer, loss of bone, and difficulties with minimally invasive surgery. Metaphyseal-engaging shortstem implants have been designed to address these issues in THA. While these devices have been studied in younger patients, it is unclear whether they offer advantages in older patients. Questions/purposes We asked whether the stability and bony ingrowth of an off-the-shelf short stem in patients 70 years and older were similar to those achieved in patients younger than 70 years at 2-year followup. Furthermore, we asked whether pain and function scores were affected by age, bone quality, or varus alignment. Patients and Methods We retrospectively reviewed 60 patients (65 hips) 70 years and older (mean, 75 years; range, 70-86 years) treated with an uncemented short stem (range, 90-105 mm). We compared radiographic alignment, stability, and bony ingrowth, as well as Harris hip scores and WOMAC pain scores, to a cohort of 89 patients (91 hips) younger than 70 years. Minimum followup was 24 months (mean, 35 months; range, 24-60 months). Results Radiographs showed proximal bony ingrowth and stable fixation of all implants. Average Harris hip score at last followup was 88 (range, 70-100) for the 70 years and older cohort and 93 (range, 70-100) for younger than 70 years cohort; no patients reported thigh pain. Postoperative WOMAC scores averaged 6 (range, 0-43) and 5 (range, 0-25), respectively.

“…Bruzzone et al [19] reported a retrospective evaluation of 87 patients who were operated upon using the ABG total hip prosthesis with a 99% survival rate for the stem and 90% for the cup. Baker et al [20] also presented good results with this stem, although there was a 17% rate of periacetabular osteolysis at 15 years.…”

Purpose The purpose of this study was to review retrospectively the cases operated upon in our department in recent years with a Wagner stem and a small socket in cases of Crowe I or II dysplastic hips. Methods We conducted a retrospective clinical radiological review of 30 hips diagnosed with hip dysplasia Crowe I or II treated in our centre between 2002 and 2008. All of them were treated with a Wagner cone stem and a small Trilogy acetabulum (Zimmer ®). Results There were 15 men and 11 women with 13 left and 17 right femurs. Mean follow-up was 43.44 months (range 14-87). Eight patients were Crowe I type and 22 were Crowe II type. Merlé d'Aubigne score pre-operatively was 12.23 and at the last follow-up was 15.54. Mean leg length inequality was 1.79 and after surgery it was 0.69 cm. Complications included three infection and three dislocations (two of them in the same patient). Conclusions The use of a Wagner stem is a good option to correct the different deformities in the proximal femur in these cases. A small socket allows a correct relocation of the acetabulum in a dysplastic socket with good bone coverage.

“…Excellent short-to mid-term results have been reported with the ABG I hip prosthesis in terms of implant fixation [6,[16][17][18] and survival rates greater than 90% at 10-year follow-up using revision as the end-point have been reported [19][20][21]. However, several studies have insisted on high rates of peri-acetabular osteolysis [17,22,23].…”
