“…Large stem size, high elasticity modulus of the stem, varus stem position, and osteoporosis of the proximal femur have been known as risk factors of thigh pain after cementless THA [8][9][10][11][12]19,20]. In this study, we could not identify any risk factors for thigh pain.…”

“…However, the frequency of thigh pain showed a high variability [1][2][3][4][5][6][7][8][9][10][11][12]20], and little information is available in terms of the time of onset and duration of the pain. Most surgeons perceived thigh pain as a transient self-resolving phenomenon, whereas others perceived this problem as a serious complication [1][2][3][4][5][6][7].…”

“…Stem subsidence was defined as downward axial stem migration relative to the position documented in the first post-operative radiograph. Only stem subsidence of ≥5 mm was considered [19]. According to Engh et al [20], femoral stems were regarded as radiographically loose when there was a progressive subsidence or a progressive widening of radiolucent lines; acetabular shells were considered as radiographically loose when there was progressive widening of radiolucent lines or a change in inclination.…”

Purpose The aim of the present study was to evaluate the clinical and radiographic results of primary total hip arthroplasty (THA) performed with the Alloclassic Variall system (a modified version of the Alloclassic Zweymüller system) and to compare them with those in the literature for the original system. Methods Between January 2001 and December 2002, 273 consecutive primary THAs were performed in 259 patients at a single centre with the study system, using ceramic-onceramic (81.7 %) or ceramic-on-highly-crosslinkedpolyethylene (18.3 %) articulations. Results At the time of this study, 28 patients (29 hips; 10.6 %) had died and 40 (43 hips; 15.8 %) were lost to follow-up. Seventeen patients (19 hips; 7.0 %) could be reached only by telephone. There were four revisions in four patients (1.5 %), all involving only the femoral component. Ten-year Kaplan-Meier survival with revision of any component for any reason as the endpoint was 98.4 % (95 % confidence interval: 96.9-100 %; 30 hips remained 'at risk'). A total of 170 unrevised patients (178 hips; 65.2 %) were assessed clinically and radiographically at a median follow-up of 9.3 years (interquartile range [IQR] 8.8-9.8 years). The median Harris hip score (HHS) was 99.9 points (IQR 97.7-100). The score did not differ significantly between the two articulations. There was no sign of radiographic loosening. Conclusions The ten-year implant survival and the HHS score outcomes for THAs performed with the novel system were in line with those documented in the literature for its predecessor.

“…High hip centres alter joint bio-mechanics and are associated with greater risks of dislocation and mobilization[12,13]. Cementless fixing in primary and revision implants has demonstrated greater survival in the medium and long-term compared to cemented fixing[13-15]. …”

AIMTo evaluate the clinical and X-ray results of acetabular components and tantalum augments in prosthetic hip revisions.METHODSFifty-eight hip prostheses with primary failure of the acetabular component were reviewed with tantalum implants. The clinical records and X-rays of these cases were retrospectively reviewed. Bone defect evaluations were based on preoperative CT scans and classified according to Paprosky criteria of Radiolucent lines and periprosthetic gaps; implant mobilization and osteolysis were evaluated by X-ray. An ad hoc database was created and statistical analyses were performed with SPSS software (IBM SPSS Statistics for Windows, version 23.0). Statistical analyses were carried out using the Student’s t test for independent and paired samples. A P value of < 0.05 was considered statistically significant and cumulative survival was calculated by the Kaplan-Meier method.RESULTSThe mean follow-up was 87.6 ± 25.6 mo (range 3-120 mo). 25 cases (43.1%) were classified as minor defects, and 33 cases (56.9%) as major defects. The preoperative HHS rating improved significantly from a mean of 40.7 ± 6.1 (range: 29-53) before revision, to a mean of 85.8 ± 6.1 (range: 70-94) at the end of the follow-up (Student’s t test for paired samples: P < 0.001). Considering HHS only at the end of follow-up, no statistically significant difference was observed between patients with a major or minor defect (Student’s t test for independent samples: P > 0.05). Radiolucent lines were found in 4 implants (6.9%). Postoperative acetabular gaps were observed in 5 hips (8.6%). No signs of implant mobilization or areas of periprosthetic osteolysis were found in the x-rays at the final follow-up. Only 3 implants failed: 1 case of infection and 2 cases of instability. Defined as the end-point, cumulative survival at 10 years was 95% (for all reasons) and 100% for aseptic loosening of the acetabular component.CONCLUSIONThe medium-term use of prosthetic tantalum components in prosthetic hip revisions is safe and effective in a wide variety of acetabular bone defects.
