“…These phenomena might provide some explanations for the observed porosis, and could represent stress shielding following the use of a cementless stem, and/or cortical thinning due to aging [8]. In terms of stability, Ha et al reported that the cortical porosis did not threaten the stability of the stems for 2-6 years postoperatively [9]. However, Lee et al…”

“…Recently, the cementless stem has been widely used for hip arthroplasty and there have been many studies reporting good results for unstable intertrochanteric fractures [3][4][5][6][7][8][9]. However, studies evaluating the long-term outcomes patients who have survived for over five years or femoral stems applied using different fixation methods according to each design have been small studies.…”

Background: Recent advances in medical systems and technologies have resulted in increased survival after intertrochanteric fractures of the femur, requiring the selection of appropriate femoral stems considering mid- to long-term durations. We performed hip hemiarthroplasty for unstable intertrochanteric fractures using a Wagner cone femoral stem (Group A) and double tapering right angled femoral stem (C2 stem, Group B), and evaluated the clinical imaging results. Methods From January 2004 to December 2013, 79 patients (79 hips) who underwent hip hemiarthroplasty with a cone stem (36 cases) and C2 stem (43 cases) were included. During the follow-up period, clinically, changes in pain (visual analog scale [VAS] score), walking ability, and Harris Hip score were examined. Radiologically, changes in the proximal femur were observed. We also reviewed the complications that occurred. Results Patients’ mean ages were 77.2 (70-83) years and 78.6 (70-84) years, and mean follow-up periods were 84.7 (60-108) months and 85.4 (60-96) years in Groups A and B, respectively. Postoperative pain (VAS score) and the Harris hip score were not significantly different between the groups until 24 months and 36 months, respectively. However, VAS scores from 36 months postoperatively and Harris hip scores from 48 months postoperatively indicated that Group B patients had significantly higher VAS scores and lower Harris hip scores. There was no significant difference in walking ability between the groups; however, in Group B, walking ability was reduced by one grade in 13 patients and by two grades in nine. Cortical bone osteoporosis occurred in four and 14 cases in Groups A and B, respectively. In Group B, five patients developed cortical bone resorption, and four of them had nonunion of trochanteric fracture fragments. Conclusions Hip hemiarthroplasty using a cementless femoral stem for unstable intertrochanteric fractures requires careful selection of the stem, considering the remaining life of the patient. When using a 3C stem for unstable intertrochanteric fractures, it is thought that the firm fixation of fractured trochanteric fragments is necessary, and for a reverse oblique fracture, it is better to use the 3B stem with a suitable length.

“…All operations were conducted by the same surgeon using an anterolateral approach and cementless femoral stems (Bencox Stem; Corentec, Cheonan, Korea) 8) . BHA was performed using Bencox bipolar cups (Corentec) and Bencox forte heads (Corentec) and THA was performed using cementless acetabular cups (Bencox cementless cup; Corentec) and ceramic-on-ceramic articulation.…”

“…Cemented hip prostheses have been used traditionally in patients with osteoporosis; however, cement-related cardiopulmonary complications have been observed in these patients 2 , 3 , 4) . Cementless total hip arthroplasty (THA) has been used with increasing frequency in recent years, as this procedure lowers the risk of cement-related cardiopulmonary complications and has the advantages of short operation times and high survival rates 5 , 6 , 7 , 8) . The choice of prostheses remains controversial due to the clinical outcomes observed following THA or bipolar hip hemiarthroplasty (BHA) 9) .…”

PurposeThe purposes of the current study were to assess the early results of cementless hip arthroplasty (HA) for femoral neck fractures in elderly patients with severe osteoporosis and to compare the clinical outcomes between those who underwent total HA (THA) or bipolar hemiarthroplasty (BHA).Materials and MethodsFrom April 2011 to May 2012, we performed 87 cementless HAs for displaced femoral neck fractures in elderly patients (≥65 years) with severe osteoporosis. Among them, we studied 70 hips that were able to be followed-up for >24 months. Of these, 34 underwent THA and 36 underwent BHA. Clinical results were evaluated using the Harris hip score (HHS), Koval classification, and radiographs.ResultsOnly one instance of femoral stem loosening was observed. Additionally, no dislocations were observed and no revision surgeries were required. The mean changes in the functional items of the HHS scores were 2.8 and 5.2 for those who underwent THA and BHA, respectively (P<0.05). According to the Koval classification used for the ambulatory status analysis, the mean perioperative change in the grade was 0.8 (0-4), with no significant differences noted between the THA and BHA groups.ConclusionThe early results of cementless HA for femur neck fractures in elderly patients with osteoporosis were satisfactory, and THA was found to have a functional advantage over BHA.
