The problems of hip arthroplasty under conditions of wide introduction of that surgical intervention into clinical practice and the perspectives of cementless wedge-shaped femoral stems use are discussed on the example of high-technology home endoprosthesis “Il’za” are discussed. Technical characteristics of the implant, peculiarities of surgical procedure with its application, early and mid-term clinical and roentgenologic results of 581 operations are considered. Stable deterioration of hip function has been noted in 1, 2 and 3 years after operation - from 37.6 points by Harris hip score to 89.3, 92.2, and 89.1 points, respectively. Survival of the femoral component in 6 years after arthroplasty made up 98.6%, general survival - 96.2%. Universality of this femoral component that enables to achieve its stable primary and secondary fixation in the absolute majority of patients is proved. The achieved data allow to talk of the reliability of wedge-shaped femoral hip stems and significant prospective for their use in wide clinical practice.

Abstract Background Total hip arthroplasty (THA) for bony ankylosis is technically challenging in patients with ankylosing spondylitis (AS). This study aimed to determine the mid-term results of bilateral synchronous THA for bony ankylosis in patients with AS. Methods Nineteen cases of bony ankylosis in patients with AS who received bilateral synchronous THA were included in this study (17 males and 2 females, mean age 49.2 years). Disease duration was 5–38 years (mean 18 years and 6 months). All patients received cementless THA. Intraoperative blood loss, visual analog scale (VAS) score, and complications were assessed. Harris hip scores evaluated the clinical effect. Results Patients were followed up for 62–98 months (mean 82.5 months). VAS score decreased from 7.42 ± 0.92 to 2.42 ± 0.83, Harris hip score improved from 21.8 ± 7.2 to 80.3 ± 6.5, and the flexion-extension range of the hip improved from 0 to 142.3 ± 6.2°. One patient with septum bronchiale had a fracture intraoperatively and was treated with wire strapping. One patient had a traction injury of the femoral nerve postoperatively and recovered 1 year after the operation. Loosening and subsidence were not observed in all patients. Heterotopic bone formation was noted in 3 patients. No complications such as joint dislocation, acute infection, and deep vein thrombosis were found. Conclusion Bilateral synchronous THA was effective for bony ankylosis of the hip in patients with AS because it improved patients’ quality of life and had satisfactory mid-term outcomes.

Dislocation of the femoral component is a common complication of total hip arthroplasty. In 44% of cases it results from the incorrect position of implant components. The aim of the study was to evaluate the efficacy of the elaborated method for determination of implant components position at preoperative planning of revision hip arthroplasty in recurrent dislocations of the femoral component. Thirty patients aged 25 - 75 years with recurrent femoral component dislocation after primary hip arthroplasty were examined. To verify the dislocation a plain anterior-posterior roentgenogram of pelvis was performed followed by MSCT of pelvis, femoral bones and knee joints. Drawing up of necessary lines and angles enabled to evaluate objectively the correctness of hip implant components position. By measurement results all patients were divided into 3 groups and in each group an appropriate type of surgical intervention was used. The proposed methods of preoperative planning enabled to determine objectively the cause of femoral component dislocation, to choose an adequate variant of surgical intervention and to exclude the risk of femoral component dislocation recurrence in 96.7% of cases.

Cemented Total Hip Arthroplasty

Sixty-two consecutive revision hip arthroplasties were carried out in 57 patients between 1986 and 1990 using the long stem Porous Coated Anatomic (PCA) prosthesis. Fifty-two hips were available for clinical and radiological review. The remainder had either died or were lost to follow-up. The average follow-up was 4.8 years (range 3-7.8 years) and the mean age was 56 years (range 25-77 years). Using the Harris Hip Score, 38/53 (73%) were regarded as good/excellent, 6/52 (11.5%) as fair and 8/52 (15.5%) as poor. The incidence of femoral component subsidence (31/52 - 60%) was a cause of concern, and accounted for two cases of late dislocation. Of the remaining six hips regarded as failures, two had been revised for acetabular graft resorption and migration of the cup while four had moderate persistent pain despite fair hip function. The authors are unable to recommend the long stem PCA prosthesis for routine use in revision hip arthroplasty.

Objective To compare medium-term clinical and radiological outcomes of primary unilateral uncemented (UN) or cemented (CE) femoral component total hip arthroplasty (THA) in elderly patients with osteoporosis. Methods Consecutive patients with osteoporosis who underwent primary unilateral UN or CE THAs at our institution from 2006 to 2013 were retrospectively reviewed. All consecutive procedures were managed by high-volume surgeons, using UN or CE THA approaches. Follow-up assessments occurred at 1, 3, 6, 9, and 12 months postoperatively, and yearly thereafter. Patient-related functional outcomes were assessed using the Harris Hip Score (HHS). Primary and secondary endpoints were early revision (<5 years) and functional outcome. Results In total, 496 primary unilateral THAs (CE, n = 184; UN, n = 182) were assessed with a median follow-up period of 75 months (range, 65–86 months). From 3 months after surgery to the final follow-up, HHS was consistently superior in the CE group. Respective prosthetic loosening rates in the UN and CE groups were 26.4% and 16.8% at a minimum of 5 years. There was a significant difference in rate of early revision (7.6% CE vs. 14.8% UN). Conclusion Compared with UN THA, CE THA exhibits a superior outcome in elderly patients with primary osteoporosis.

Aims The diversity of femoral morphology renders femoral component sizing in total hip arthroplasty (THA) challenging. We aimed to determine whether femoral morphology and femoral component filling influence early clinical and radiological outcomes following THA using fully hydroxyapatite (HA)-coated femoral components. Methods We retrospectively reviewed records of 183 primary uncemented THAs. Femoral morphology, including Dorr classification, canal bone ratio (CBR), canal flare index (CFI), and canal-calcar ratio (CCR), were calculated on preoperative radiographs. The canal fill ratio (CFR) was calculated at different levels relative to the lesser trochanter (LT) using immediate postoperative radiographs: P1, 2 cm above LT; P2, at LT; P3, 2 cm below LT; and D1, 7 cm below LT. At two years, radiological femoral component osseointegration was evaluated using the Engh score, and hip function using the Postel Merle d’Aubigné (PMA) and Oxford Hip Score (OHS). Results CFR was moderately correlated with CCR at P1 (r = 0.44; p < 0.001), P2 (r = 0.53; p < 0.001), and CFI at P1 (r = − 0.56; p < 0.001). Absence of spot welds (n = 3, 2%) was associated with lower CCR (p = 0.049), greater CFI (p = 0.017), and lower CFR at P3 (p = 0.015). Migration (n = 9, 7%) was associated with lower CFR at P2 (p = 0.028) and P3 (p = 0.007). Varus malalignment (n = 7, 5%), predominantly in Dorr A femurs (p = 0.028), was associated with lower CFR at all levels (p < 0.05). Absence of spot welds was associated with lower PMA gait (p = 0.012) and migration with worse OHS (p = 0.032). Conclusion This study revealed that femurs with insufficient proximal filling tend to have less favourable radiological outcomes following uncemented THA using a fully HA-coated double-tapered femoral component.

Primary Hip Arthroplasty

Background and purpose — Total hip arthroplasty (THA) is an effective and common procedure. However, persistent pain and analgesic requirement up to 2 years after THA surgery are common. We examined the trends in the utilization of analgesics before and after THA, overall, and in relation to socioeconomic status (SES) in a populationbased cohort. Patients and methods — We used the Danish Hip Arthroplasty Register to identify 103,209 patients who underwent THA between 1996 and 2018. Data on prescriptions and SES markers was obtained from Danish medical databases. Prevalence rates of redeemed prescriptions for analgesics with 95% confidence intervals were calculated for 4 quarters before and 4 quarters after THA for the entire THA population, and by 3 SES markers (education, cohabiting status, and wealth). Results — Overall, the prevalence of analgesic use prior to surgery was 42% at 9–12 months and 59% at 0–3 months before the THA. The prevalence of analgesics reached its highest at 64% 0–3 months after THA but declined to 27% at 9–12 months after THA. Low education, living alone, and having low wealth (low SES) were associated with higher prevalence of analgesics use both before and after THA. Interpretation — 59% of patients used analgesics 0–3 months before surgery, which could indicate that THA might not be considered the last option for treatment and that surgery criteria might depend more on factors such as patient preferences or hip function. Moreover, health professionals should prioritize the use of a detailed plan when phasing out analgesics after THA to counteract unnecessary use, especially when treating patients with low SES.
