The effect of zoledronic acid and high-dose vitamin D on function after hip fractures. A prospective cohort study.

PURPOSE: Hip fractures are associated with functional decline and increased mortality. The aim of this study was to investigate the effect of zoledronic acid and high-dose vitamin D on function and mortality after hip fractures. PATIENTS AND METHODS: Forty-five patients received zoledronic acid and high dose of vitamin D during hospitalization after fracture management. These patients were compared with a control group of 46 patients. Pre- and postoperative prospectively collected data including ASA score, Charlson comorbidity score, presence of dementia, Vitamin D, and the Barthel index were available. Final follow-up was performed after one year. Primary outcome was patients' function at final follow-up as measured with Barthel index score. Secondary outcomes included mortality, assessment of pain, and complications. RESULTS: Barthel index score at final follow-up was decreased in both groups. There was no significant difference in Barthel index between the two groups (15.5 ± 5.0 vs 15.8 ± 5.8, p = 0.850). However, the Barthel index in the control group decreased beyond the smallest detectable change (3 points). Mortality was statistically different between groups (8.8% vs 28.2%, p = 0.047). Complications and pain at final follow-up were not different between groups. Multivariate analysis revealed that preoperative Barthel index and Charlson comorbidity score independently affected function at final follow-up. Logistic regression analysis disclosed that not receiving active treatment and complications were associated with increased mortality. CONCLUSIONS: Medical treatment after surgical management of hip fractures results in reduced mortality and lessens the functional decline associated with these fractures.

Prioritising of hip and knee arthroplasty procedures during the COVID-19 pandemic: the European Hip Society and the European Knee Associates Survey of Members.

PURPOSE: During the COVID-19 pandemic there has been a massive reduction of arthroplasty services due to reallocation of hospital resources. The unique challenge for clinicians has been to define which arthroplasty patients most urgently require surgery. The present study aimed to investigate priority arthroplasty procedures during the pandemic and in the reinstatement period from the surgeon's perspective. MATERIAL AND METHODS: An online survey was conducted among members of the European Hip Society (EHS), European Knee Associates (EKA) and other invited orthopaedic arthroplasty surgeons (experts) from across the world. The survey consisted of 17 different arthroplasty procedures/indications of which participants were asked to choose and rank the most important 10. RESULTS: Four hundred and thirty-nine arthroplasty surgeons from 44 countries responded. The EHS and EKA had a 43% response rate of members. In weighted average points, the majority of respondents (67.5 points) ranked 'acute fractures requiring arthroplasty (Periprosthetic fractures, THA/hemi-arthroplasty for femoral neck fractures)' as priority indication number one, followed by 'first-stage explantations for acute PJI (periprosthetic joint infection)' in second place and priority indication (45.9 points) three as 'one-stage revision for acute PJI' (39.7 points). CONCLUSIONS: There was agreement that femoral neck fractures, periprosthetic fractures, and acute infections should be prioritised and cannot be postponed in the setting of the COVID-19 pandemic. As arthroplasty procedures are being resumed in most countries now, there has also been a relaxation of lockdown rules in most countries, which might cause a so-called second wave of the pandemic. Therefore, the results of the current study present a proposal by experts as to which operations should be prioritised in the setting of a second wave of the pandemic.

Evaluating the "Patella-Friendly" Concept in Total Knee Arthroplasty: A Minimum 15-Year Follow-Up Outcome Study Comparing Constant Radius, Multiradius Cruciate-Retaining, and Nonanatomical Cruciate-Retaining Implants.

BACKGROUND: Patella-friendly femoral components were developed in order to reduce anterior knee pain and patellofemoral complications in total knee arthroplasty (TKA), but their effect on long-term outcome is still unclear. METHODS: We retrospectively evaluated prospectively collected data from 3 groups consisting of 100 patients (100 knees in each). In group A, the constant radius a-MP, in group B the multiradius cruciate-retaining Genesis II, and in group C the nonanatomic, multiradius, cruciate-retaining AGC TKA was implanted. Patients of all groups were matched for age, gender, side, body mass index, and length of follow-up. Preoperative and postoperative clinical outcome data in the form of Knee Society System (KSS), Short Form-12, Western Ontario and McMaster University Osteoarthritis Index, and Oxford Knee Score were available at regular intervals for groups A and B. For patients of group C, KSS score data were available at the same time intervals. In all groups, the patellofemoral compartment was assessed using the Clinical Patella Score scale. Anterior knee pain, secondary patella resurfacing, implant failure, and radiological outcome were assessed in patients of all groups. RESULTS: At 10-year and 15-year follow-up, patients of group A showed statistically significant (s.s.) higher (all P = .000) KSS values as compared to those of groups B and C. At 15-year follow-up, patients of group B showed s.s. higher (P = .001) KSS values as compared to those of group C. At 10-year and 15-year follow up, patients of group A showed s.s. higher (all P = .00) Western Ontario and McMaster University Osteoarthritis Index and Oxford Knee Score values as compared to those of group B. At 15-year follow-up only, patients of group A showed s.s. higher (P = .00) Short Form-12 (physical) values as compared to those of group B. In terms of Clinical Patella Score, patients in group A had s.s. higher values (P = .05) when compared to those of groups B and C. Anterior knee pain was recorded in 4.4% of TKAs in group A, 7.5% in group B, and 17.2% in group C. One (1.1%) patient in group A, 3 (3.25%) in group B, and 7 (8%) in group C underwent secondary resurfacing. CONCLUSION: Anatomical, patella-friendly, constant radius femoral components outperform others in reducing anterior knee pain and patella complications in TKA in which the patellae are left nonresurfaced.

Preparation for the next COVID-19 wave: The European Hip Society and European Knee Associates recommendations.

PURPOSE: To plan for the continuance of elective hip and knee arthroplasty during a resurgence or new wave of COVID-19 infections. METHOD: A systematic review was conducted using the terms "COVID-19" or "SARS-Cov-2" and "second wave". No relevant citations were found to inform on recommendations the plan. Therefore, an expert panel of the European Hip Society and the European Knee Associates was formed to provide the recommendations. RESULTS: Overall, the recommendations consider three phases; review of the first wave, preparation for the next wave, and during the next wave. International and national policies will drive most of the management. The recommendations focus on the preparation phase and, in particular, the actions that the individual surgeon needs to undertake to continue with, and practice, elective arthroplasty during the next wave, as well as planning their personal and their family's lives. The recommendations expect rigorous data collection during the next wave, so that a cycle of continuous improvement is created to take account of any future waves. CONCLUSIONS: The recommendations for planning to continue elective hip and knee arthroplasty during a new phase of the SARS-Cov-2 pandemic provide a framework to reduce the risk of a complete shutdown of elective surgery. This involves engaging with hospital managers and other specialities in the planning process. Individuals have responsibilities to themselves, their colleagues, and their families, beyond the actual delivery of elective arthroplasty.

Failure in diagnosis and under-treatment of osteoporosis in elderly patients with fragility fractures.

We evaluated whether osteoporosis is adequately managed and treated in patients suffering from fragility fractures. Factors that influenced osteoporosis diagnosis and treatment rates were also assessed. To this end, patients with the principal diagnosis of low-energy hip, vertebral, or distal radius fractures were recruited for the study. Collected data included risk factors for osteoporosis, history of previous fractures, known history of osteoporosis, and osteoporosis treatment at the time of admission. The patients' prefracture risk profile was also assessed to determine whether osteoporosis could have been identified prior to the index fracture. We identified 308 patients with fragility fractures, including 214 hip, 41 vertebral, and 53 distal radius fractures. Overall, 238 patients (77.3%) had at least one risk factor for osteoporosis. Eighty-eight patients (28.6%) had sustained ≥ 1 prior fragility fractures in the past. However, only 79 patients (25.6%) were aware that they had osteoporosis and even fewer (66 patients, 21.4%) had been receiving osteoporosis treatment preceding the current admission. Anti-osteoporotic agents were more commonly prescribed in patients 66-75 years old (p = 0.008), with a family history of osteoporosis (p = 0.009) or history of a prior fragility fracture (p = 0.012). The treatment rate was higher in women than men (p = 0.026) and in patients with vertebral or multiple prior fractures compared to patients with prior hip fractures. The current study provides evidence that individuals who experience fragility fractures are not adequately managed for osteoporosis. Only few of the historically known risk factors for osteoporosis were adequately recognized and associated with osteoporosis evaluation and treatment.

Great trochanter bursitis vs sciatica, a diagnostic-anatomic trap: differential diagnosis and brief review of the literature.

PURPOSE: The purpose of this study is to point out the difficulty of differentiating great trochanter bursitis (GTB) from sciatica and estimating the prevalence of GTΒ, in patients poorly diagnosed with sciatica in their first visit to the general practitioner and referred to a spine infirmary. METHODS: The diagnosis of GTΒ was made based on history and physical examination, and was confirmed by ultrasonography and/or response to an anesthetic plus corticosteroid injection to the trochanteric bursa. Demographic and clinical characteristics of the study group were evaluated. The statistical analysis was held with the SPSS pc package (version 24.0). RESULTS: In a total of 657 referrals for sciatica, 72 patients (10.95%) were incorrectly diagnosed as suffering from sciatica, whereas, in fact, they were suffering from GTΒ. In addition, 18 patients (2.74%) were diagnosed as suffering from persistent sciatica with coexisting GTΒ. More women than men had GTΒ (79-11). Mean age for patients with sciatica diagnosis but suffering from GTΒ was 60 years. Mean age for patients with both sciatica and GTΒ was 61 years. CONCLUSIONS: The GTB is a common clinical entity in middle-aged women, which can escape from the physician in cases of incomplete medical history and clinical examination, leading to unnecessary imaging tests and treatment approaches, burdening both the patient and the health system. Early diagnosis of GTB may dramatically reduce cost, prevent unwanted and inappropriate imaging exams and treatment, and make the patient free of symptoms immediately.

A 9-Year Outcome Study Comparing Cancellous Titanium-Coated Cementless to Cemented Tibial Components of a Single Knee Arthroplasty Design.

BACKGROUND: The cemented Advance Medial-Pivot total knee arthroplasty (TKA) was designed to reflect contemporary knee kinematics data and has shown satisfactory long-term outcomes. METHODS: We retrospectively evaluated prospectively collected data from 2 groups of patients. Group A consisted of 54 patients (54 TKAs), 18 men and 36 women, and mean age at surgery was 63.2 ± 5.2 years; group B consisted of 54 patients (54 TKAs), 17 men and 37 women, and mean age at surgery was 63.8 ± 5.1 years. Patients of both groups were matched for age, gender, side, body mass index, and length of follow-up. The cementless components of this design were implanted in group A and the cemented in group B. Implant failure, complication rates, clinical (both subjective and objective) and radiological outcomes were assessed in all patients of both groups. RESULTS: All patients of both groups were available for final follow-up evaluation at a mean of 8.6 ± 0.4 years. Survival analysis at 9 years showed a cumulative success rate of 100% in both groups with all end points. In neither group were implant-related, surgeon-related, or patient-related failures observed. When both groups were compared, in all time intervals, no differences were recorded on Knee Society system, Western Ontario and McMaster University Osteoarthritis Index, Short Form-12, and Oxford Knee Scores. On radiological examination, for both groups, all parameters evaluated were satisfactory. CONCLUSION: This study presents satisfactory midterm clinical and radiological outcomes with the use of both versions of this design. Moreover, no implant-related failures were observed with the use of cancellous titanium-coated tibial implants.

Anatomical variations of the foramen transversarium in cervical vertebrae: findings, review of the literature, and clinical significance during cervical spine surgery.

PURPOSE: To describe certain anatomical variations of the foramen transversarium, in spine cervical vertebrae in a contemporary specimen of an Indo-European population and approach their clinical importance during cervical spine surgery. METHODS: 102 cervical vertebrae (C2-C7) from 17 different skeletons, intact without any degenerative or traumatic disorders, which belonged to the collection of the Department of Anatomy, were examined. The age of specimens at the time of their death was between 25 and 65 years. All foramina were measured with a digital caliper. RESULTS: The average size of the normal foramina was: 6.49 mm × 5.74 mm on the right side and 6.65 mm × 5.76 mm on the left side. Regarding the variations, we found two cervical vertebrae (1.96 %), one C3 and one C6, in which the right foramen transversarium is clearly smaller than the left. The exact dimensions of these foramina are: 2.3 mm × 2.5 mm on the right side and 6.54 mm × 8 mm on the left side in the first vertebra and 2.8 mm × 3.74 mm on the right side and 6 mm × 7.5 mm on the left side, in the second one. We also observed double foramina in 14 vertebrae (13.72 %). In seven vertebrae, the duplication was bilateral (6.86 %). We finally found one vertebra (0.98 %) with triplication of the foramen transversarium on the left side. CONCLUSIONS: Summarizing, 10 out of our 17 skeletons were presented with variations (extremely narrow or multiple foramina). This finding of hypoplastic, duplicated and triplicated foramina transversaria in unexpectedly high rates raises questions about the integrity of the contained structures, the possibility of a different path for them. These variations may induce an extra-osseous position of the vertebra artery, and the ignorance of such an event may have catastrophic consequences during a surgery in the cervical spine.

Oxidized zirconium head on crosslinked polyethylene liner in total hip arthroplasty: a 7- to 12-year in vivo comparative wear study.

BACKGROUND: Osteolysis resulting from wear debris production from the bearing surfaces is a major factor limiting long-term survival of hip implants. Oxidized zirconium head on crosslinked polyethylene (XLPE) is a modern bearing coupling. However, midterm in vivo wear data of this coupling are not known. QUESTIONS/PURPOSES: The purpose of this study was to investigate in vivo whether the combination of an oxidized zirconium femoral head on XLPE produces less wear than a ceramic head on XLPE or a ceramic head on conventional polyethylene (CPE) couplings and whether any of these bearing combinations results in higher hip scores. METHODS: Between 2003 and 2007, we performed 356 total hip arthroplasties in 288 patients; of those, 199 (69.1%) patients (199 hips) were enrolled in what began as a randomized trial. Unfortunately, after the 57(th) patient, the randomization process was halted because of patients' preference for the oxidized zirconium bearing instead of the ceramic after (as they were informed by the consent form), and after that, alternate allocation to the study groups was performed. Hips were allocated into four groups: in Group A, a 28-mm ceramic head on CPE was used; in Group B, a 28-mm ceramic head on XLPE; in Group C, a 28-mm Oxinium head on XLPE; and in Group D, a 32-mm Oxinium head on XLPE. The authors prospectively collected in vivo wear data (linear wear, linear wear rate, volumetric wear, and volumetric wear rate) using PolyWare software. Preoperative and postoperative clinical data, including Harris and Oxford hip scores, were also collected at regular intervals. Of those patients enrolled, 188 (95%) were available for final followup at a minimum of 7 years (mean, 9 years; range, 7-12 years). RESULTS: All bearing surfaces showed a varying high bedding-in effect (plastic deformation of the liner) up to the second postoperative year. At 5 years both oxidized zirconium on XLPE groups showed lower (p < 0.01) volumetric wear (mean ± SD mm(3)) and volumetric wear rates (mean ± SD mm(3)/year) (Group C: 310 ± 55-206 ± 55 mm(3)/year, Group D: 320 ± 58-205 ± 61 mm(3)/year) when compared with ceramic on CPE (Group A: 791 ± 124-306 ± 85 mm(3)/year) and ceramic on XLPE (Group B: 1420 ± 223-366 ± 88 mm(3)/year) groups. For those patients who had completed 10 years of followup (20 patients [44.5%] of Group A, 21 [45.7%] of Group B, 23 [47.9%] of Group C, and 22 [44.9%] of Group D), at 10 years, both oxidized zirconium on XLPE groups also showed lower (p < 0.01) volumetric wear (mean ± SD mm(3)) and volumetric wear rates (mean ± SD mm(3)/year) (Group C: 356 ± 64 to 215 ± 54 mm(3)/year, Group D: 354 ± 50 to 210 ± 64 mm(3)/year) when compared with ceramic on CPE (Group A: 895 ± 131 to 380 ± 80 mm(3)/year) and ceramic on XLPE (Group B: 1625 ± 253 to 480 ± 101 mm(3)/year) groups. When wear rates of both oxidized zirconium groups were compared, no differences were found at any time interval with the numbers available. Two hips (one from Group A and one from Group B) are scheduled for revision as a result of wear and osteolysis. There were no differences in hip scores among the groups with the numbers available. CONCLUSIONS: In this study, in vivo wear parameters were lower when the combination of an oxidized zirconium head on XLPE liner was used at an average of 9 years (range, 7-12 years) followup. Further larger-scale clinical studies should confirm these findings and evaluate osteolysis and revision rates in association with the use of this bearing coupling. LEVEL OF EVIDENCE: Level II, therapeutic study.

Patient-reported quality of life after primary major joint arthroplasty: a prospective comparison of hip and knee arthroplasty.

BACKGROUND: To investigate and compare the impact of primary hip (THA) and knee (TKA) arthroplasty on quality of life in patients with osteoarthritis, to determine patients' satisfaction with total joint arthroplasty, and to detect the effect of patients' demographic and clinical characteristics on outcome. METHODS: Three hundred seventy eight (378) patients with hip (174) and knee (204) osteoarthritis undergoing total joint arthroplasty (174 THA-204 TKA) were assessed pre- and post-operatively (6 weeks, 3, 6, and 12 months) using the Western Ontario and McMaster Osteoarthritis Index (WOMAC) and Centre for Epidemiological Studies Depression Scale (CES-D10). The patients' satisfaction with the results of total joint arthroplasty was also assessed. Differences were analyzed using general linear model for repeated measures. RESULTS: The one-year response rate was 97 % for THA and 90 % for TKA. WOMAC and CES-D10 scores improved significantly after one year for both THA and TKA (P < 0.0001). The improvement in WOMAC total score was significantly greater for TKA patients (P < 0.0001 at 12 months). WOMAC pain and stiffness improved earlier for THA (6 weeks), while TKA had equivalent improvements at 3 and 6 months respectively. Both THA/TKA displayed significant improvement of WOMAC function at 3 months but TKA had greater improvement. Age, body mass index, residence, education and social support were not significant predictors of quality of life after total joint arthroplasty. One year postoperatively 88 % of patients were satisfied. CONCLUSIONS: WOMAC and CES-D10 improved significantly one year postoperatively. Although pain and stiffness improved earlier in THA, functional improvement was inferior in THA compared to TKA.

Punitive limb amputation.

BACKGROUND: Limb amputation has been carried out through the ages as a punitive method in various parts of the world. This article highlights the historical and societal background associated with the use of punitive limb amputation. METHODS: We performed an extensive electronic search of the pertinent literature augmented with a hand-search of additional sources. RESULTS: Evidence for punitive amputation is available as early as the court of the Babylonian Code of King Hammurabi (circa 1750 Before the Common Era [BCE]), which imposed punitive limb amputations on slaves who used force against free citizens. Other reports provided evidence that punitive amputation was used as early as the 4th century BCE in ancient Peru. Limb amputation restored law and order during the Roman and Byzantine periods. Amputation as a punitive instrument prevailed in Europe throughout the 17th century. During the Enlightenment, the intellectual movement in Europe approached criminal law from a humanistic perspective, incorporated it into societal practice, and promoted its preventive dimensions. Punitive limb amputation still exists in several Arab and African countries. CONCLUSION: Amputation as a punitive or correctional method has its roots in old civilizations. It has been used through the ages in various parts of the world. While it has been abandoned in modern western societies, punitive amputation is still used in several third-world countries.

Bilateral Acute Achilles Tendon Rupture Can Be Effectively Treated Non-operatively.

Acute rupture of the Achilles tendon (AT) is a common but debilitating injury that requires immediate diagnosis and effective management. Spontaneous bilateral AT rupture is rare; however, it can lead to severe disability for a significant period. This case report presents a 76-year-old patient who suffered a bilateral AT rupture while engaging in a non-strenuous activity. Upon confirmation of the diagnosis by physical examination and radiologic evaluation, conservative treatment was decided due to the presence of numerous comorbidities. A personalized rehabilitation protocol was implemented, allowing weight-bearing activities using Achilles boots at six weeks. Healing of both ATs was confirmed by an MRI at three months. Our case shows that non-operative treatment of these injuries can result in exceptionally favorable outcomes and should not be disregarded. However, thorough patient compliance and surveillance are prerequisites.

Development of Prediction Model for 1-year Mortality after Hip Fracture Surgery.

Purpose: Hip fractures are associated with increased mortality. The identification of risk factors of mortality could improve patient care. The aim of the study was to identify risk factors of mortality after surgery for a hip fracture and construct a mortality model. Materials and Methods: A cohort study was conducted on patients with hip fractures at two institutions. Five hundred and ninety-seven patients with hip fractures that were treated in the tertiary hospital, and another 147 patients that were treated in a secondary hospital. The perioperative data were collected from medical charts and interviews. Functional Assessment Measure score, Short Form-12 and mortality were recorded at 12 months. Patients and surgery variables that were associated with increased mortality were used to develop a mortality model. Results: Mortality for the whole cohort was 19.4% at one year. From the variables tested only age >80 years, American Society of Anesthesiologists category, time to surgery (>48 hours), Charlson comorbidity index, sex, use of anti-coagulants, and body mass index <25 kg/m2 were associated with increased mortality and used to construct the mortality model. The area under the curve for the prediction model was 0.814. Functional outcome at one year was similar to preoperative status, even though their level of physical function dropped after the hip surgery and slowly recovered. Conclusion: The mortality prediction model that was developed in this study calculates the risk of death at one year for patients with hip fractures, is simple, and could detect high risk patients that need special management.

Appraisal of the clinical practice guidelines on thromboprophylaxis in orthopaedic procedures; Do we AGREE (II)?

OBJECTIVE: Optimal thromboprophylaxis in orthopaedic procedures is crucial in an attempt to lower the risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism. We aim to: 1) identify clinical practice guidelines (CPGs) and recommendations (CPRs) on thromboprophylaxis in adult patients undergoing orthopaedic procedures, and 2) assess the methodological quality and reporting clarity of these guidelines. METHODS: The study was conducted following the 2020 PRISMA guidelines for a systematic review and has been registered on the international prospective register of systematic reviews (PROSPERO) under the registration number (CRD42023406988). An electronic search was conducted using Medline, Embase, Cochrane, Web of Science, Google Scholar and medRxiv. The search terms used were ""adults", "orthopedic surgery", "orthopedic surgeries", "orthopedic surgical procedure", "orthopedic surgical procedures" "english language", "venous thromboembolism", in all possible combinations (January 2013 to March 2023). The eligible studies were evaluated by four blind raters, employing the Appraisal of Guidelines for Research & Evaluation II (AGREE-II) analysis tool. RESULTS: The literature research resulted in 931 studies. Finally, a total of 16 sets of guidelines were included in the current analysis. There were 8 national and 8 international CPGs. Eight CPGs made specific recommendations for orthopaedic surgery and referred mostly to joints; one guideline focused on pelvi-acetabular trauma, while the rest were more inclusive and non-specific. Four guidelines, one from the American Society of Hematology (ASH), two from the United Kingdom (UK) and one from India were found to have the highest methodological quality and reporting clarity according to the AGREE-II tool. Inter-rater agreement was very good with a mean Cohens Kappa 0.962 (95 % CI, 0.895-0.986) in the current analysis. So, the reliability of the measurements can be interpreted as good to excellent. CONCLUSION: Optimal thromboprophylaxis in orthopaedic procedures is crucial. The available guidelines were found to be mostly of high methodological quality and inter-rater agreement was very good, according to our study.

Revision total hip arthroplasty for aseptic loosening compared with primary total hip arthroplasty for osteoarthritis: long-term clinical, functional and quality of life outcome data.

PURPOSE: The aim of this study was the comparative assessment of long-term clinical (subjective and objective), functional and quality of life outcome data between primary and revision THA. METHODS: 122 patients (130 hips) who underwent cementless revision THA of both components (TMT cup, Wagner SL stem, Zimmer Biomet) for aseptic loosening only (Group A) were compared to a matched group of 100 patients (100 hips) who underwent cementless primary THA for osteoarthritis (Synergy stem, R3 cup, Smith & Nephew) (Group B). Outcomes were evaluated with survival analysis curves, Harris Hip Score (HHS), WOMAC, Oxford Hip Score (OHS), Short-Form Health Survey (SF-12) and EQ-5D-5L scales. Mobility was assessed with walking speed, Timed Up And Go Test (TUG), Parker Mobility Score, Lower Extremity Functional Scale (LEFS) and UCLA scores. RESULTS: At a mean follow-up of 11.1 (8-17) years a cumulative success rate of 96% (95% CI, 96-99%) in Group A and 98% (95% CI, 97-99%) in Group B with operation for any reason as an endpoint was recorded. Statistically significant differences between groups were developed for WOMAC (Mann-Whitney U-test, p = 0.014), OHS (Mann-Whitney U-test, p = 0.020) and physical component of SF-12 scores (Mann-Whitney U-test, p = 0.029) only. Group A had less improvement in function as compared with group B. In Group A, in multiple regression analysis, patients' cognition (p = 0.001), BMI (p = 0.007) and pain (p = 0.022) were found to be independent factors influencing functional recovery (WOMAC). Similarly, pain (p = 0.03) was found to influence quality of life (EQ-5D-5). CONCLUSIONS: In the long term, revision THA shows satisfactory but inferior clinical, functional, and quality of life outcomes when compared to primary THA. Residual pain, BMI and cognitive impairment independently affect functional outcomes.

Coexisting Benign Tumors in a Finger Are Rare but Not Impossible.

Giant cell tumors of the tendon sheath (GCTTS) and enchondroma are identified as the most prevalent benign soft tissue and bone tumors of the hand. While their individual presence is a common finding, their concurrent appearance in the same anatomic region is exceptionally rare, making simultaneous diagnosis more burdensome. We present a noteworthy case of GCTTS and enchondroma in the index finger of a young patient, along with the therapeutic strategy for correct diagnosis and effective treatment of such an occurrence.

Treatment of periprosthetic femoral fractures following total hip arthroplasty: results of an online survey of the European Hip Society.

BACKGROUND: Periprosthetic femoral fractures (PPF) are a devastating complication after total hip arthroplasty (THA). Both trauma and adult reconstruction surgeons or combined teams treat these fractures following management algorithms. The aim of this study is to investigate the current treatment of PPF by members of the European Hip Society (EHS). METHODS: An online survey of the members of the European Hip Society (EHS) was conducted. 20 cases of periprosthetic fracture were presented and surgeons were asked to answer questions regarding classification, treatment and postoperative treatment protocol. RESULTS: A total of 132 (130 male; 2 female) EHS members responded. Mean years in surgical practice was 18.8 (min. 1 year; max. 50 years). The preferred surgical method was combined open reduction and internal fixation (ORIF) (30.3%) for AG fractures, ORIF with cables (30.4%) for AL fractures, combined ORIF (cable and plate) for B1 fractures (49.2%), stem revision with cables for B2 fractures (73.1%), stem revision with cables for B3 (55.9%) fractures and combined ORIF (cable and plate: 55.5%) for C fractures. Surprisingly, 10.8% suggested various stem revision techniques for B1 and 17.4% for C fractures. Strong variations were observed regarding postoperative weight-bearing protocol. CONCLUSIONS: A strong consensus was found for the choice of conservative or surgical treatment of the different PPF types according to the Vancouver Classification. Various stem revision techniques were the preferred surgical techniques for Vancouver B2 (91.2%) and B3 (88.6%) fractures. However, for postoperative weight-bearing, when the ORIF technique was used, a significant variation of protocols was found.

Solitary Radio-Opaque Lesion of Wrist (Tumoral Calcinosis) Disappears Spontaneously After Causing Acute Carpal Tunnel Syndrome: A Case Report.

CASE: We describe the case of a 53-year-old male patient with a history of acute carpal tunnel syndrome (CTS) provoked by a radio-opaque mass on the palmar side of the wrist. Although the mass disappeared in new radiographs 6 weeks later without any intervention apart from the carpal tunnel release, excisional biopsy was conducted on the residue, revealing tumoral calcinosis. CONCLUSION: Both acute CTS and spontaneous resolution are clinical manifestations of this rare condition on suspicion of which biopsy can be avoided by following a "wait and see" strategy.

Personal protection equipment for orthopaedic and trauma surgery during the COVID-19 pandemic: The results of an EFORT survey initiative.

Orthopaedic and trauma surgeons performing surgery in the COVID-19 pandemic environment faced problems with availability, use, rationing, modification, compliance and recycling of personal protection equipment (PPE). Orthopaedic and trauma surgeons were not well informed concerning the use of PPE for aerosol-generating orthopaedic and trauma procedures. Scientific bodies, health authorities and management have provided insufficient guidelines for the use of PPE in aerosol-generating orthopaedic and trauma procedures. The availability of specific PPE for orthopaedic and trauma operating theatres is low. Hospital management and surgeons failed to address the quality of operating theatre ventilation or to conform to recommendations and guidelines. Operating theatre PPE negatively affected surgical performance by means of impaired vision, impaired communication, discomfort and fatigue. Existing PPE is not adequately designed for orthopaedic and trauma surgery, and therefore, novel or modified and improved devices are needed.

Clinical, functional and radiographic outcomes after revision total hip arthroplasty with tapered fluted modular or non-modular stems: a systematic review.

PURPOSE: The aim of the study was to systematically evaluate clinical outcomes of tapered fluted stems, either monoblock or modular, in revision total hip arthroplasty. METHODS: PubMed, EMBASE and Web of Science and Cochrane databases were systematically searched by 2 researchers. Clinical studies reporting primarily on survival and re-revision rates, and secondarily on subsidence, dislocation, intraoperative fractures, periprosthetic fractures and infection were included. 2 investigators assessed the quality of the studies. RESULTS: 46 studies were included in this review, reporting on 4601 stem revisions. The pooled re-revision rate was 5.1% and long-term survival ranged from 75% to 98.5%. No differences were observed between monoblock and modular stems regarding re-revision rate, dislocation rate, periprosthetic fracture rate or infection rates. Monoblock stems exhibited more subsidence and modular stems displayed more intraoperative fractures. CONCLUSIONS: Satisfactory results can be obtained with the use of tapered fluted end-bearing stems. Monoblock stems offer the same clinical results as modular stems.
