Noncemented hip replacement using a conical titanium metal-backed screw-in cup to be implanted with precutting of the threads (TITAN-METAL-BACKED, AlloPro, Baar, Switzerland), in combination with a straight conical press-fit stem (Zweymüller-“hochgezogen”, AlloPro, Baar, Switzerland) was evaluated clinically and radiologically in 64 consecutive primary arthroplasties with an average 7.2 year follow-up. The clinical results compare very favourably with other cementless systems. The Harris hip score revealed an improvement from 45 to 84. The Merle d'Aubigné index showed an increase during the case-control period from 16 to 26. Thigh pain was practically absent except in one patient. A radiographic appearance of bone ingrowth around the acetabular component was found in nearly all cases. Only one cup migrated in a patient with a large cystic lesion in the acetabular roof, which was not grafted, with no other signs of loosening. Additionally this patient had chemotherapy. In all other cases there were no signs of cup migration, significant radiolucency, osteolysis or definite cup loosening. Around the stem, primary cortical contact was mainly located in the distal zones. Radiolucent lines appeared only proximally, with few exceptions, and were, except in four cases, always smaller than 2 mm. They were never circumferential and usually combined with sclerotic lines. Only one stem subsided, but the patient remained asymptomatic. There was a high incidence of proximal bone atrophy, distal cortical thickening and endosteal bone formation, not correlating with radiological loosening or clinical symptoms. Signs of femoral osteolysis were absent. No patient had to be revised.

Total hip arthroplasty (THA) in patients with sequelae of the hip joint infection is a technically challenging procedure. In addition, the majority of such patients are less than fifty years old, so it has been reported that they have higher prevalence of complication and failure of component fixation. Alumina-on-alumina couplings are an attractive alternative and may offer a promising option for such young active patients. We analyzed 33 primary cementless alumina-onalumina THAs (PLASMACUP®SC-BiCONTACT® system incorporating BIOLOX® forte) that had been performed in patients who had sequelae of the hip joint infection. The average age of the patients was 37.8 years (range, 19-68 years) and 26 patients were younger than 50 years old. They were followed-up for more than 5 years (average, 74 months; range, 60-93 months). All hips had no recurrence of hip joint infection. The mean Harris hip score improved from 59.8 points to 93.5 points. All of the implants had radiographic evidence of a bone ingrowth and no radiological loosening was found. During the follow-up period, no cup or stem was revised and no periprosthetic osteolysis was observed. Nonunion of the osteotomized greater trochanter occurred in one hip, but no postoperative infection or ceramic failure was observed. The 5-year minimum follow-up clinical results of modern alumina-on-alumina THAs performed in patients with sequelae of the hip joint infection were encouraging with regard to osteolysis and implant stability. Our findings show that this alternative articulation offers a reliable solution for these young patients with long-standing anatomic abnormalities of the bone and soft tissues.

Objective To compare the clinical outcomes of primary metal-on-metal total hip replacement (MoM-TR) converted to uncemented total hip replacement (UTR) or cemented total hip replacement (CTR) in patients with femoral neck fractures (AO/OTA: 31B/C). Methods Patient data of 234 UTR or CTR revisions after primary MoM-TR failure from March 2007 to January 2018 were retrospectively identified. Clinical outcomes, including the Harris hip score (HHS) and key orthopaedic complications, were collected at 3, 6, and 12 months following conversion and every 12 months thereafter. Results The mean follow-up was 84.12 (67–100) months for UTR and 84.23 (66–101) months for CTR. At the last follow-up, the HHS was better in the CTR- than UTR-treated patients. Noteworthy dissimilarities were correspondingly detected in the key orthopaedic complication rates (16.1% for CTR vs. 47.4% for UTR). Statistically significant differences in specific orthopaedic complications were also detected in the re-revision rate (10.3% for UTR vs. 2.5% for CTR), prosthesis loosening rate (16.3% for UTR vs. 5.9% for CTR), and periprosthetic fracture rate (12.0% for UTR vs. 4.2% for CTR). Conclusion In the setting of revision of failed primary MoM-TR, CTR may demonstrate advantages over UTR in improving functional outcomes and reducing key orthopaedic complications.

In recent years, various uncemented proximal metaphyseal hip stems were introduced for younger patients as a bone preserving strategy. Initial osteodensitometric analyses of the surrounding bone of short stems indicate an increase of bone mass with secondary bone ingrowth fixation as a predictor of long-term survival of these types of implants. We report the outcome of 151 modular Metha short hip stem implants in 148 patients between March 2005 and October 2007. The mean follow-up was 5.8±0.7 years and the mean age of the patients was 55.7±9.8 years. Along with demographic data and co-morbidities, the Harris Hip Score (HHS), the Hip dysfunction and Osteoarthritis Outcome Score (HOOS), and also the results of a patient-administered questionnaire were recorded pre-operatively and at follow-up. The mean HHS increased from 46±17 pre-operatively to 90±5 the HOOS improved from 55±16 pre-operatively to 89±10 at the final follow-up. A total of three patients have been revised, two for subsidence with femoral revision and one for infection without femoral revision (Kaplan Meier survival estimate 98%). The radiological findings showed no radiolucent lines in any of the patients. The modular Metha short hip stem was implanted in younger patients, who reported an overall high level of satisfaction. The clinical and radiographic results give support to the principle of using short stems with metaphyseal anchorage. However, long-term results are necessary to confirm the success of this concept in the years to come.

We retrospectively reviewed the clinical, radiographic, and survivorship outcomes in a series of 180 patients that underwent 204 primary Total Hip Arthroplasties with the use of a second generation threaded hydroxyapatite-coated acetabular cup that was implanted without any supplementary supporting screws. At an average follow-up period of 10.2 (range: 8–14) years, one hundred and seventy-four patients (198 cups) were available for assessment. All patients underwent detailed physical and radiographic examination; their functional status was evaluated according to the Harris Hip Score (HHS). Following their digitization, all radiographs were further reviewed in order to determine the existence of any migration of the acetabular cup. Osteolytic lesions, radiolucent lines or zones of increased bone density were also recorded and classified according to the system of DeLee & Charnley. The modified Engh's criteria were used in order to evaluate the stability of the prosthesis. The patients' mean HHS at their latest follow-up visit (97.24 points) was statistically significantly better than the preoperative mean score of 40.31 points (p<0.001). Radiographic analysis showed “stable with bone ingrowth” fixation (modified Engh's criteria) of all implants with no significant migration of the cup (mean cranial migration: 0.597 mm, mean horizontal migration: 0.607 mm, mean observed difference of the cup's inclination angle: 0.26 degrees). No areas of significant osteolysis were found. The cumulative survival rate of the implants was 97.05%. Our results suggest that second generation hydroxyapatite-coated threaded acetabular cups can be successfully implanted (and achieve excellent results) without the use of any supplementary supporting screws.

Introduction: Hip resurfacing arthroplasty (HRA) or Total hip replacement (THR), as it is popularly called, attempts to mollify these basic clinical problems, in patients with a hip arthritic problem, which may be of a sequela to age-related degeneration, osteonecrosis, systemic disorder like Rheumatoid arthritis (RA) or Ankylosing spondylosis (AS) or as a result of trauma and or an old infection. The basic pathology, is an unfavourable and abrading hip diarthrodial joint. The endeavour of the study was, to establish the efcacy of the Posterior vs Lateral approach for THA/THR, by studying their outcomes in primary THR. This prospective study was undertaken at Che Materials And Methods: ttinad Hospital and Research Institute (CARE), Kelambakkam, Chengalpattu district, Tamilnadu, In the Department of Orthopaedics from Jan 2017 to Dec 2020 (48 months). The Functional outcome of hip surgery was measured using the Harris Hip Score, Oxford hip score and the WOMAC. Rivermead visual gait analysis (RVGA) method was used post-operatively to assess the gait. The Biomechanical outcomes of Abductor Gait Component, were individually assessed by EMG studies. The Harris Hip Score, The Oxford Hip S Results: core and WOMAC score, when the lateral approach was compared to the posterior approach pre-op and post-op in the 12 months minimum follow-up period, the laterally approached group faired better. The VAS score was equivocal. The comprehensive RVGA assessment also showed marginally better results for the laterally approached group as was the case with the Trendelenburg test score. The EMG studies for the Gluteus Maximus, Medius and the lateral rotators of hip also favoured the outcomes for the laterally approach hips. The supremacy of the Lateral Approach, ove Conclusion: r Posterior Approach, cannot be adjudged in a short-term follow-up study. It is thus opined that the Lateral Approach may be statistically and data wise superior, but the patient satisfaction, which is a major factor, is almost the same in both the approach groups. The follow-up needs to be atleast for a decade for us to be able to come to any meaningful conclusion. With regards to surgery like the Total hip replacement, which have a longevity factor exceeding 10 years, studies have to be followed up for periods in excess of 10 years.

Introduction: Internal snapping hip syndrome (ISHS) is caused by the iliopsoas tendon snapping over either the iliopectineal ridge or the anterior femoral head. Excellent results are achieved only with activity modification, rest, and stretching the iliopsoas muscle. The literature favors iliopsoas tendon release if conservative therapy fails. There is little evidence about the gold standard of this condition. Objective: Describe clinical results, complicactions and recurrence rate of arthroscopic treatment of ISHS. Methods: We included all patients who failed conservative treatment and were treated with arthroscopy for ISHS between March 2012 and March 2018. Patients with less than 2 years of follow up and previous surgery on the hip were excluded. We performed Ilizariturri´s technique with a transcapsular endoscopic release in central compartment. We registered modified Harris hip score (MHHS), Hip outcome score activity of daily living (EHOSDL), patients satisfaction, recurrence rate and complications. Results: Eight patients were included. Average follow up was 36 months (range 24-60 months). MMHS improved from preoperative average score of 70 (range 62-72) to postoperative average of 93 (range 92 to 96). Average EHOSDL improvement was 30% (from 55% preoperative to 85% postoperative). All patients had excellent results. Average patient satisfaction was 8 (range 7-9). We had no recurrence or complications. Conclusion: Arthroscopic treatment of ISHS allowed us to obtain very good clinical results with no complications or recurrences with a minimum 2 years follow up.

Category: Ankle, Arthroscopy Introduction/Purpose: The purpose of this study was to describe the long-term clinical and radiological outcome of a new arthroscopic fixation technique for primary osteochondral talar defects: Lift, Drill, Fill and Fix (LDFF). Methods: Twenty-five patients underwent an arthroscopic LDFF surgery for osteochondral talar defects. Two of these patients underwent surgery on both ankles. During the LDFF technique, the OCD was identified after which an osteochondral flap was created and lifted (lift-phase). The bone flake of the OCD as well as the osteosclerotic area of the bed was drilled (drill phase). Cancellous bone was harvested from the distal tibia and transported into the defect until there was sufficient substantial filling (fill phase). Finally, the osteochondral flap was fixed with an absorbable biocompression screw (fix phase). The mean follow-up was 63 months (SD 9.2). Pre- and postoperative clinical assessment included the Foot and Ankle Outcome Score (FAOS) and the numeric rating scales (NRS) of pain at rest and during walking. Remodeling and bone ingrowth after LDFF were analyzed on computed tomography scans during follow-up at one year after the surgery. Results: All patients were available for final follow-up. At final follow-up, LDFF led to a significant improvement of the NRS of pain during rest and the NRS of pain during walking in all patients. The FAOS significantly improved on all 5 subscales: pain, symptoms, activities of daily living, sport and recreation and quality of life. The NRS of pain at rest significantly improved from 2.3 to 1.0 (p = 0.01), and pain with walking significantly improved from 5.7 to 1.6 (p < 0.001). In total 24 out of 25 patients, and 26 out of 27 ankles, showed remodeling and bone ingrowth on CT scans 1 year after the arthroscopic fixation procedure. No complications occurred. Conclusion: Arthroscopic LDFF of an osteochondral talar defect shows good long-term results at 5 year follow-up after surgery. Although the radiological results at 1-year follow-up and the long-term clinical results are encouraging, more patients and long- term radiological follow-up is necessary in order to identify prognostic factors on outcomes.

Introduction and methods: From January 2004 to December 2008, 188 total hip arthroplasties were performed using a cemented dual mobility cup. 174 patients were available for final analysis. Their mean age was 76.8 (range 54-98 years). The mean follow-up was 7.7 years (range 5-10 years). Results: There were no dislocations. Survivorship rates of the femoral and acetabular components were 100% at a minimum of 5 years. At the latest follow-up, the mean Harris Hip Score significantly increased from 31.6 (only arthritic patients) points preoperatively to 84.5 points. No patients had progressive osteolysis, component migration, or loosening on radiographs. 2 patients presented with periprosthetic fractures treated conservatively. 2 patients presented with infection treated without implant removal and 1 patient presented with transient femoral palsy. Conclusions: The results of this consecutive series confirmed the good performance of the cemented dual mobility cup at mean 7.7 years follow-up with no revision and no dislocations.

Objective – to analyze there sults of treatment of patients with fusiform aneurysms (FA) depending on localization and type of surgery.Materials and methods. In the period from 2007 to 2019 127 patients with intracranial fusiform cerebral aneurysms underwen treatment in Scientific and Practical Center of Endovascular Neuroradiology of the National Academy of Medical Sciences of Ukraine. 133 fusiform aneurysms were identified. The following neuroimaging methods were used to diagnose FA: magnetic resonance imaging, multispiral computed tomography and cerebral selective angiography according to Seldinger. In this study, patients with fusiform aneurysms are divided according to localization in the FA of the carotid poolsand the FA of the vertebrobasilar basin. Patients with FA of carotid basins were 56 (27 (29 (51.8 %) men and 48.2 %) women). The average age of patients was 45.2 year. 31 (55.3 %) patients were operated. Patients with FA in the vertebrobasilar basin were 71 (43 (60.6 %) men and 28 (39.4 %) women). The average age of patients was 54.5 year. It was operated 48 (67.6 %) patients.Results. It was possible to completely eliminate FA from the bloodstream intraoperative in 16 (51.6 %) patients. In the early postoperative period in this group 5 (16.1 %) patients had a decrease in disease symptoms, in 3 (9.6 %) patients neurological symptoms increased. In other patients the dynamics of neurological manifestations remained unchanged. There were nofatal out comes in either the early or late post operative period. According to the extended Glasgow outcome scale at the time of discharge from the hospital 22 (71 %) patients had > 5 points, 9 (29 %) – 4 points. In the period from 3 to 5 weeks 2 symptomatic thromboses of flow-directingstents were noted, in the form of clinical manifestations of ischemic stroke. In the period from 3 to 6 months 22 (71 %) patients underwent control examination. Angiographically in 19 (86.3 %) revealed a completes hut down of FA from the bloodstream, in 3 (13.7 %) – decrease of volume of FA > 65 %. Clinical symptoms completely regressed in 16 (72.7 %) patients, partially regressed – in 3 (13.7 %), increased – in 2 (13.6 %). In the period from 12 to 18 months 7 (31.8 %) patients underwent control examination. Total FA shut down from the bloodstream was detected in 5 (71.4 %) patients, in 2 (28.6 %) aneurysms decreased by 80 %. Eighteen-month survival was 100 %.It was possible to intraoperatively switch off FA in the vertebrobasilar basin from the bloodstream in 11 (22.9 %) cases. In the early postoperative period a partial regression of neurological symptoms was observed in 7 (14.5 %) patients. In 10 (20.8 %) cases a new or increasing neurological deficit was observed after intracranial stent implantation, which partially regressed against the background of conservative treatment. Four (8.3 %) deaths were recorded in the early postoperative period. The clinical results of 48 patients on the Glasgo woutcome scale at the time of discharge were > 5 points in 27 (56.2 %) patients, 4 points – in 17 (35.4 %) and 1 points – in 4 (8.3 %). In the period from 3 to 6 months 19 (39.5 %) patients underwent control examination. Angiographically in 14 (73.7 %) patients the aneurysm was completely turned off from the blood circulation, in 2 (10.5 %) the decrease in the volume of the aneurysm was > 70 %, in 3 (15.8 %) patients the decrease in the volume of the aneurysm was 47–64 %. Clinical symptoms regressed in 7 (36.8 %) patients, a decrease in neurological deficit was noted in 2 (10.5 %) patients, an increase in neurological deficit in 3 (15.8 %) patients. Three deaths were recorded. In the period from 12 to 18 months, 12 (25 %) patients underwent control examination. Angiographically in 10 (83.3 %) patients FA was excluded totally from the bloodcirculation, in 2 (16.7 %) – the volume of aneurysm was reduced by 80 %. Clinical symptoms regressed in 8 (66.6 %) patients and increased in 1 (8.3 %). During the control period 2 patients died. The 18-month survival rate was 89.5 %, 5 (10.5 %) patients died.Conclusions. Fusiform aneurysms are more common in people of working age, more common in men. A more unfavorable course of the disease occursin patients with symptomatic FA of the vertebrobasilar basin, due to the compression and dysfunction of the brainstem and stem structures. Deconstructive methods for eliminating FA from the bloodstream provide long-termsatis factory treatment results, butrequire careful selection of patients for such in terventions. Endovascular treatment should be considered as the main treatment, asitentails fewer risks for the patient. For aneurysms that cannot be treated with endovascular methods, microsurgical treatments hould be considered. The main forsuccess ful treatment of patients with fusiform aneurysms is th ecareful selection of patients and individual approach to the choice of treatment based on the shape, location and size of the FA.
