Filter by:The investigators primary objective of this study is to evaluate radiographic fit and fill of the Insignia stem and identify risk factors for aseptic failure. The investigators hypotheses being tested is: the newly designed Insignia stem demonstrates acceptable radiographic fit and fill by reviewing radiolucent lines <2mm.
Total hip arthroplasty (THA) is one of the most common orthopedic surgical procedure and is associated with severe pain in the immediate postoperative period, thus limiting early recovery. Postoperative pain management in THA requires multimodal analgesia, combining drugs and injection of a local anesthetic (LA). But, the best anesthesia strategy to provide optimal postoperative analgesia in THA remains controversial. Opioid free anesthesia could limit the episodes of hyperalgesia as well as tolerance and addiction to opioids. The hypothesis of this study is that an opioid free anesthesia using dexmedetomidine could improve analgesia after THA. The main objective of this monocenter, prospective, randomized, triple-blind, controlled trial is to assess the interest of opioid free anesthesia using dexmedetomidine on morphine consumption after THA.
A prospective, non-randomized, single-center clinical study to determine the accuracy of a patient-specific instrument (OPS™) for delivering a planned femoral component anteversion and neck resection using a Direct Anterior Approach (DAA) in Total Hip Arthroplasy.
This is a single-center retrospective observational cohort study of consecutively operated patients who underwent total hip arthroplasty with a SYMBOL CUP DMR HA or a SYMBOL CUP DM CEM hemispherical dual mobility acetabular implant. The purpose of this study is to estimate the safety and efficacy of those two implants at two-year follow-up.

Summary from initial protocol Goal: Validation of the uncoated SL-PLUS® MIA stem within an observation study Study design: prospective, single-center, observational, non-comparative study Study population: 135 consecutive cases (uncoated SL-PLUS® MIA implants) Intervention (if applicable): Implantation of a total hip endoprosthesis Main goals/endpoints: Radiological: radiolucent lines, osteolysis, hypo- and hypertrophy of the cortex, loosening of the implant or migration; clinical: Harris Hip Score, implant-related complications, revisions; patient questionnaire (WOMAC) Type and extent of the risks associated with the study participation as well as benefits for the patient: All patients will benefit from the hip prostheses without exception. There are no increased risks for the patients participating in the study compared to patients who do not participate. Normal, necessary follow-up exams will be performed over the course of 10 years. These follow-up exams will then be quantitatively evaluated within the scope of the study in accordance with a standardized protocol. Accordingly, the benefit for the patients from the participation in the study is currently not yet foreseeable.
Summary from initial protocol Goal: Validation of the HA (hydroxylapatite) coated SL-PLUS™ stem within an observation study Study design: prospective, multicenter, observational, non-comparative study Study population: 240 consecutive cases (HA-coated implants), 60 cases per study site Intervention (if applicable): Implantation of a total hip endoprosthesis Main goals/endpoints: Radiological: radiolucent lines, osteolysis, hypo- and hypertrophy of the cortex, loosening of the implant or migration; clinical: Harris Hip Score, implant-related complications, revisions; patient questionnaires HOOS and EQ-5D Type and extent of the risks associated with the study participation as well as benefits for the patient: All patients will benefit from the hip prostheses without exception.

Interest of obturator nerve block for analgesia in total hip arthroplasty remains controversial. This regional anesthesia procedure could provide post-operative pain relief as obturator nerve is responsible for innervation of the internal part of the hip joint capsule. This randomized double-blind study aims to assess obturator nerve block for post-operative analgesia in total hip arthroplasty. Before the surgery, an ultrasound guided obturator nerve block will be performed with either 20cc of saline or ropivacaine 0.2% (a long-acting local anesthetics). After regional anesthesia, a general anesthesia will be performed for intraoperative period. This study aims to assess post-operative pain management during the first 24 hours. Ability to walk the day of the surgery will also be collected.
Summary from initial protocol Goal: Validation of the HA (hydroxylapatite) coated SLPLUS ™ MIA stem within an observation study Study design: prospective, multicenter, observational, noncomparative study Study population: 300 consecutive cases (HA-coated implants), 60 cases per study site. Intervention (if applicable): Implantation of a total hip endoprosthesis Main goals/endpoints: Radiological: radiolucent lines, osteolysis, hypo- and hypertrophy of the cortex, loosening of the implant or migration. Clinical: Harris Hip Score, HOOS Score, EQ-5D, implant-related complications, revisions Type and extent of the risks associated with the study participation as well as benefits for the patient: All patients will benefit from the hip prostheses without exception. There are no increased risks for the patients participating in the study compared to patients who do not participate. Normal, necessary follow-up exams will be performed over the course of 10 years. In addition, study patients are asked to provide information on their general state of health and the condition of their hip in two questionnaires. These clinical and radiological follow-up exams will then be quantitatively evaluated within the scope of the study in accordance with a standardized protocol. Accordingly, the direct benefit for the patients from the participation in the study is currently not yet foreseeable.
