Short Femoral Stem

Background We present the result of our experience in using a short femoral stem in elderly patients (>70 years of age) compared to patients younger than 70 years. Methods Data were prospectively collected on 138 patients who underwent 148 primary total hip arthroplasty (THA), with a conservative short stem between November 2010 and June 2014. The cohort was divided into 2 groups: the study group (group 1) comprised 57 patients (60 THA) over 70 years of age at the time of surgery, with a mean age of 75.4 years (range 70-87 years) and a mean follow-up of 26.7 months (range 9-48 months). The control group (group 2) comprised 81patients (88 THA) less than 70 years of age with a mean age of 57.4 years (range 33-69 years) and a mean follow-up of 27.3 months (range 9-54 months). Hip function in the 2 groups was compared preoperatively and postoperatively using the Merle D'Aubigne hip score (MD) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) score. Results At the latest follow-up, 1 calcar fracture was reported in a 54-year-old patient in the control group, which required fixation with a screw and had a favourable outcome. No cases of clinical or radiographic loosening were reported. Clinical results showed no statistically significant differences between the 2 groups. Conclusions The use of the GTS conservative short stem in patients over 70 years old has shown very good results and low complication rates, comparable to those for patients younger than 70 years.

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.

Background. The purpose of our study is to compare the results of supine and lateral decubitus positions for total hip arthroplasty (THA) with the direct lateral (DL) approach in overweight and obese patients. Methods. Patients who had a THA with the DL approach using the lateral decubitus position (LD group) (n=54) or supine position (S group) (n=45) were retrospectively investigated. Demographic characteristics, age, and body mass indexes were calculated. Blood loss of patients, amount of transfusion, Harris Hip Scores (HHSs) (preop, 6 weeks, 3 months, 6 months, and 12 months), incision size, surgery time, postoperative acetabular cup inclination angle, femoral stem alignment, follow-up period, hospital stay, preoperative-postoperative leg length inequality, and complication rates (infection, wound site problems, and dislocation rates) were compared. Results. Both groups did not differ from each other by means of age, gender, BMI, and affected side (p=0.814, p=0.723, p=0.582, and p=0.833, respectively). The incision length (p<0.001), blood loss (p=0.010), and amount of blood transfused (p=0.002) were significantly higher in the S group than in the LD group. The surgical time was significantly longer in the S group (p<0.001). There were no statistically significant differences between the LD and S groups in terms of pre- and postoperative height, cup inclination, stem alignment, duration of hospital stay, and follow-up period. The change between pre- and postoperative HHS in the LD and S groups was statistically significant. Post hoc binary comparison analysis was conducted to investigate the difference between the groups. The values of HHS were significantly increased from the preoperative period to the final follow-up. Conclusions. The LD and S groups had comparable functional outcomes one year postoperatively. However, the S group was associated with worse intraoperative outcomes than the LD group.

Abstract Aim The length of the femoral stem in total hip arthroplasty (THA) is a practical consideration to prevent gait impairment. The aim of this study was to determine if reducing the femoral stem length in THA would lead to impaired gait biomechanics. Methods Patients uniformly with the same brand implant of differing lengths (100 mm vs 140–166 mm) were taken retrospectively from a prospective trial introducing a new short stem. Twelve patients without any other disorder to alter gait besides contralateral differing length stem THA were tested at differing gradients and speed on a validated instrumented treadmill measuring ground reaction forces. An anthropometrically similar group of healthy controls were analysed to compare. Results With the same posterior surgical approach, the offset and length of both hips were reconstructed within 5 mm of each other with an identical mean head size of 36 mm. The short stem was the last procedure for all the hips with gait analysis occurring at a mean of 31 and 79 months postoperatively for the short and long stem THA, respectively. Gait analysis between limbs of both stem lengths demonstrated no statistical difference during any walking condition. In the 90 gait assessments with three loading variables, the short stem was the favoured side 51% of the time compared 49% for the long stem. Conclusion By testing a range of practical walking activities, no lower limb loading differences can be observed by reducing the femoral stem length. A shorter stem demonstrates equivalence in preference during gait when compared to a reputable conventional stem in total hip arthroplasty.

Abstract BackgroundThe increase rate seen in Total Hip Arthroplasty (THA) for younger patients has implications for future rehabilitation demands for primary and revision THA surgery. This study aims to determine the impact of a 6-week post-operative rehabilitation program designed for THA patients ≤ 60 years on physical activity (PA) and function compared to age- and a sex-matched control group received usual postoperative care at 12-week post-THA. MethodsIn this quasi-experimental study, a cohort of THA candidates was recruited during their 6-week postoperative visit to their surgeons. The out-patient rehabilitation program consisted of 12 structured exercise classes (2 hrs/class) over 6 weeks. Physical activity was assessed using Sense Wear Pro ArmbandTM [SWA]. Participants completed the Hip Osteoarthritis Outcome Score (HOOS), and THA satisfaction questionnaire before and immediately after the intervention. ResultsThe intervention group took significantly more steps/day at the follow-up compared to baseline. The intervention group had a higher mean change in the number of weekly PA bouts than the control group. Within the intervention groups, all HOOS subscales were significantly higher at the follow-up compared to baseline. ConclusionThe augmented rehabilitation program may have immediate effects on pain relief and symptom reduction for patients (≤60 years) following THA.

The Mean

The aim of this study was to investigate the radiological and clinical outcome of the direct anterior approach (DAA) in total hip arthroplasty (THA) using a collared cementless femoral short-stem. This retrospective study included 124 patients with 135 THAs operated from 2014 to 2016 using a collared cementless triple tapered hydroxyapatite-coated femoral short-stem (AMIStem H Collared®, Medacta International, Castel San Pietro, Switzerland) implanted with a DAA. Follow-up was performed at three months, 12 months, and five years. Clinical outcome was assessed using the hip osteoarthritis outcome score (HOOS) and radiological analysis was done using conventional radiographs, which included evaluation of the femur morphology based on Dorr classification, of radiolucencies based on the Gruen zone classification and of stem subsidence. The mean age was 67.7 ± 11.3 years and the mean body mass index (BMI) was 27.4 ± 4.4 kg/m2. The stem survival rate at five years was 99.1% with one revision due to recurrent dislocations. Mean HOOS score improved from 40.9 ± 18.3 preoperatively to 81.5 ± 19.7 at three months, 89.3 ± 10.9 at 12 months, and 89.0 ± 14.0 at five years (all with p < 0.001). No significant correlations were found between age, femoral bone morphology, BMI and HOOS, and the appearance of relevant radiolucencies.

Abstract Background Placement of femoral stem in excessive anteversion or retroversion can cause reduced range of motion, prosthetic impingement, and dislocation. The aim of this study was to assess the operative femoral anteversion in patients treated with total hip arthroplasty (THA) and analyze the need of adjusting stem anteversion. Methods We retrospectively included 101 patients (126 hips) who underwent cementless THA with a manual goniometer to determine the femoral anteversion between October 2017 and December 2018. The operative femoral anteversion we measured was recorded during THA. We further divided those hips into three subgroups based on the range of operative femoral anteversion: group 1 (<10°), group 2 (10–30°), and group 3 (>30°) and compared the differences of their demographic data. Univariate and multivariate logistic regression were used to identify the influencing factors for the need of neck-adjustable femoral stem. The clinical and radiographic outcomes were also assessed. Perioperative complications were recorded. Results After THA, the Harris hip scores improved from 52.87 ± 15.30 preoperatively to 90.04 ± 3.31 at the last follow-up (p < 0.001). No implant loosening, stem subsidence, and radiolucent lines were observed on radiographs. No severe complications occurred and no components needed revision at the latest follow-up. The mean operative femoral anteversion was 14.21° ± 11.80° (range, −9 to 60°). Patients with femoral anteversion more than 30° were about 10 years younger than others. Femoral anteversion >30° was more common in patients with developmental dysplasia of the hip (DDH). There were totally 14 hips treated with the neck-adjustable femoral stem. From the univariate analysis, we can observe that female sex, diagnosis of DDH (compared with osteonecrosis), and higher operative femoral anteversion and its value >30° (compared with <10°) are associated with higher rates of using the neck-adjustable femoral stem. However, all these factors were no longer considered as independent influencing factors when mixed with other factors. Conclusions This study highlighted the significance of operative femoral anteversion. Identification of abnormal femoral anteversion could assist in adjusting stem anteversion and reduce the risk of dislocation after THA.

Introduction: The best treatment of acetabular chondral flaps during surgery for femoroacetabular impingement (FAI) is unknown. We asked if subchondral drilling improves clinical and radiographic outcome and if there are factors predicting failure. Methods: We treated 79 patients with symptomatic FAI and acetabular chondral flaps with surgical hip dislocation between January 2000 and December 2007. Exclusion of all patients with previous hip pathology or trauma resulted in 62 patients (80 hips). The chondral flap was slightly debrided in 43 patients/51 hips (control group). In 28 patients/29 hips (study group), additional osseous drilling was performed. 4 patients (5 hips, 6%) were lost to follow-up. Mean follow-up was 9 years (5–13 years). The groups did not differ in demographic data, radiographic parameters or follow-up. Clinical outcome was assessed with the Merle d’Aubigné score, modified Harris Hip Score and University of California Los Angeles activity score and progression of osteoarthritis with the Tönnis grade. Results: No patient underwent conversion to total hip arthroplasty (THA) in the drilling group compared to 7 patients (8 hips, 16%) in the control group ( p = 0.005); in the remaining hips, clinical scores and progression of Tönnis grade did not differ. Increased acetabular coverage, age and body mass index were univariate predictive factors for conversion to THA. No drilling was as an independent predictive factor for conversion to THA (hazard ratio 58.07, p = 0.009). Conclusion: Subchondral drilling under acetabular chondral flaps during surgical treatment of FAI is an effective procedure to reduce the rate of conversion to THA.
