RESUMO
INTRODUCTION: Dead space management following debridement surgery in chronic osteomyelitis or septic non-unions is one of the most crucial and discussed steps for the success of the surgical treatment of these conditions. In this retrospective clinical study, we described the efficacy and safety profile of surgical debridement and local application of S53P4 bioactive glass (S53P4 BAG) in the treatment of bone infections. METHODS: A consecutive single-center series of 38 patients with chronic osteomyelitis (24) and septic non-unions (14), treated with bioactive glass S53P4 as dead space management following surgical debridement between May 2015 and November 2020, were identified and evaluated retrospectively. RESULTS: Infection eradication was reached in 22 out of 24 patients (91.7%) with chronic osteomyelitis. Eleven out of 14 patients (78.6%) with septic non-union achieved both fracture healing and infection healing in 9.1 ± 4.9 months. Three patients (7.9%) developed prolonged serous discharge with wound dehiscence but healed within 2 months with no further surgical intervention. Average patient follow-up time was 19.8 months ± 7.6 months. CONCLUSION: S53P4 bioactive glass is an effective and safe therapeutic option in the treatment of chronic osteomyelitis and septic non-unions because of its unique antibacterial properties, but also for its ability to generate a growth response in the remaining healthy bone at the bone-glass interface.

BACKGROUND: This study analyzes the effect of frailty and Post-Operative Delirium (POD) on the functional status at hospital discharge and at 4-month follow-up in patients with hip fracture (HF). METHODS: Multicenter prospective observational study of older patients with HF admitted to 12 Italian Orthogeriatric centers (July 2019-August 2022). POD was assessed using the 4AT. A 26-item Frailty Index (FI) was created using data collected on admission. The outcome measures were Cumulated Ambulation Score (CAS) ≤ 2 at discharge and a telephone-administered CAS ≤ 2 after 4 months. Poisson regression models were used to assess the effect of frailty and POD on outcomes. RESULTS: 984 patients (median age 84 years, IQR = 79-89) were recruited: 480 (48.7%) were frail at admission, 311 (31.6%) developed POD, and 158 (15.6%) had both frailty and POD. In a robust Poisson regression, frailty alone (Relative Risk, RR = 1.56, 95% Confidence Intervals, CI 1.19-2.04, p = 0.001) and its combination with POD (RR = 2.57, 95% CI 2.02-3.26, p < 0.001) were associated with poor functional status at discharge. At 4-month follow-up, the combination of frailty with POD (RR 3.65, 95% CI 1.85-7.2, p < 0.001) increased the risk of poor outcome more than frailty alone (RR 2.38, 95% CI 1.21-4.66, p < 0.001). CONCLUSIONS: POD development exacerbates the negative effect that frailty exerts on functional outcomes in HF patients.

The cardioprotective effects of sodium glucose cotrasponter 2 (SGLT2) inhibitors seem to be independent from the effects on glycemic control, through little-known mechanisms. In this study, we investigate whether the cardioprotective effects of empagliflozin, a SGLT2 inhibitor, may be associated with myocardial sympathetic activity and inflammatory cell infiltration in an experimental model of angiotensin II-dependent hypertension. Angiotensin II (Ang II), Ang II plus Empagliflozin, physiological saline, or physiological saline plus empagliflozin were administered to Sprague Dawley rats for two weeks. Blood pressure was measured by plethysmographic method. Myocardial hypertrophy and fibrosis were analysed by histomorphometry, and inflammatory cell infiltration and tyrosine hydroxylase expression, implemented as a marker of sympathetic activity, were evaluated by immunohistochemistry. Ang II increased blood pressure, myocardial hypertrophy, fibrosis, inflammatory infiltrates and tyrosine hydroxylase expression, as compared to the control group. Empagliflozin administration prevented the development of myocardial hypertrophy, fibrosis, inflammatory infiltrates and tyrosine hydroxylase overexpression in Ang II-treated rats, without affecting blood glucose and the Ang II-dependent increase in blood pressure. These data demonstrate that the cardioprotective effects of SGLT2 inhibition in Ang II-dependent hypertension may result from the myocardial reduction of sympathetic activity and inflammation and are independent of the modulation of blood pressure and blood glucose levels.

BACKGROUND: Clinical outcomes and potential complications associated with Bone-Patellar Tendon-Bone (BPTB) graft in skeletally immature ACL reconstruction (ACLR) are poorly defined. Considering that in Tanner 1-2 patients this kind of graft is not recommended, we focused our systematic review on the evaluation of all the studies in the literature that reported clinical outcomes and rate of complications of the ACLR using BPTB graft in Tanner 3-4 patients. METHODS: This review was conducted in accordance with the PRISMA statement. PubMed, Cochrane Library, EMBASE and Scopus were examined from 1965 to 2020 using different combinations of the following keywords: "ACL reconstruction", "skeletally immature", "young", "patellar tendon" and "BPTB". The database search yielded 742 studies, on which we performed a primary evaluation. After carrying out a full-text evaluation for the inclusion criteria, 4 studies were included in the final review and assessed using the Newcastle-Ottawa scale. Ninety-six cases with mean age of 14.2 years were reported. RESULTS: Good stability and functional outcomes were reported with a mean follow-up of 49.5 months. Return to sport rate ranged from 91.7% to 100%. A KT-1000 side-to-side difference higher than 5 mm was observed in five patients (5.2%). No lower limb length discrepancy and angulation were reported. Graft rupture rate was 5.2%. CONCLUSION: According to these results, BTPB graft could be a good choice in Tanner 3-4 patients who want to achieve their preinjury sport level with a low risk of growth disturbances and graft failure. Further investigations in a wider population are needed.

OBJECTIVE: To explore the effect of frailty, alone and in combination with post-operative delirium (POD), on the risk of poor function at discharge in patients with hip fracture (HF). METHODS: This is a prospective cohort study of patients with HF admitted to an Orthogeriatric Unit (OGU) between October 1, 2011 and March 15, 2019. POD was assessed using the 4AT and the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5-edition criteria. A 22-items Frailty Index (FI) was created using the data collected on admission. The outcome measure was the Cumulated Ambulation Score (CAS) score at discharge. A log-binomial regression model was used to assess the effect of frailty and POD on CAS. RESULTS: A total of 988 patients (median age = 84.9 years, Interquartile range = 80.6-89.2) were included: 360 patients (36.4%) were frail and 411 (42%) developed POD. Poor functional status at discharge (CAS score ≤2) was more common in frail than non-frail patients (68.3% vs. 53.8%, p < 0.001) In a regression adjusted for confounders, frailty alone (Relative Risk, RR = 1.33, 95% Confidence Intervals, CI = 1.14-1.55) and POD alone (RR 1.38, 95% CI = 1.2-1.59) were associated with poor functional status at discharge; when combined, frailty and POD had an interaction, yielding a mild increase in the risk of poor outcome (RR 1.47, 95% CI = 1.28-1.69). CONCLUSIONS: In older patients undergoing HF surgery, frailty, POD and their combination, are associated with poor functional status at discharge.

BACKGROUND: General physiotherapy is a common means of rehabilitation after surgery for proximal humeral fracture (PHF). Better-targeted exercises seem worthy of investigation and the aim of this study was to assess the efficacy of a rehabilitation program including task-oriented exercises in improving disability, pain, and quality of life in patients after a PHF. METHODS: By means of a randomized controlled trial with one-year follow-up, 70 working patients (mean age of 49 ± 11 years; 41 females), who were selected for open reduction and internal fixation with plates caused by PHF, were randomized to be included in an experimental (n = 35) or control group (n = 35). There was a permuted-block randomization plan, and a list of program codes was previously created; subsequently, an automatic assignment system was used to conceal the allocation. The first group underwent a supervised rehabilitation program of task-oriented exercises based on patients' specific job activities, and occupational therapy. The second group underwent general physiotherapy, including supervised mobility, strengthening and stretching exercises. Both groups individually followed programs of 60-min session three times per week for 12 weeks in the outpatient setting. The Disability Arm Shoulder Hand questionnaire (DASH; scores range from 0 to 100; primary outcome), a Pain intensity Numerical Rating Scale (scores range 0 to 10; secondary outcomes), and the Short-Form Health Survey (scores range from 0 to 100; secondary outcomes) assessed the interventions. Participants were evaluated before surgery, before and after rehabilitation (primary endpoint), and at the one-year follow-up (secondary endpoint). A linear mixed model analysis for repeated measures was carried out for each outcome measure (p < 0.05). RESULTS: Time, group and time by group showed significant effects for all outcome measures in favour of the experimental group. The DASH and the DASH work achieved clinically important between-group differences of 16.0 points (95% confidence interval [C.I.] 7.3 to 24.7) and 19.7 (95% C.I. 9.0 to 30.5) at follow-up, respectively. The NRS achieved a between-group difference of 2.9 (95% C.I. 1.0 to 3.9) at follow-up. As for SF-36, there were between-group differences ranging from 17.9 to 37.0 at follow-up. CONCLUSIONS: A rehabilitation program based on task-oriented exercises was useful in improving disability, pain, and quality of life in working patients after PHFs. Improvements lasted for at least 12 months. TRIAL REGISTRATION: On 16/12/2019, the trial was retrospectively registered in the ISRCTN registry with the ID number 17996552 .

Compound 21 (C21), an AT2 receptor agonist, and Angiotensin 1-7 (Ang 1-7), through Mas receptor, play an important role in the modulation of the protective arm of the renin-angiotensin system. The aim of this study was to investigate in an experimental model of angiotensin II-dependent hypertension whether the activation of the potentially protective arm of the renin-angiotensin system, through AT2 or Mas receptor stimulation, counteracts the onset of myocardial fibrosis and hypertrophy, and whether these effects are mediated by inflammatory mechanism and/or sympathetic activation. Sprague Dawley rats (n = 67) were treated for 1 (n = 25) and 4 (n = 42) weeks and divided in the following groups: (a) Angiotensin II (Ang II, 200 ng/kg/min, osmotic minipumps, sub cutis); (b) Ang II+Compound 21 (C21, 0.3 mg/kg/day, intraperitoneal); (c) Ang II+Ang 1-7 (576 µg/kg/day, intraperitoneal); (d) Ang II+Losartan (50 mg/kg/day, per os); (e) control group (physiological saline, sub cutis). Systolic blood pressure was measured by tail cuff method and, at the end of the experimental period, the rats were euthanized and the heart was excised to evaluate myocardial fibrosis, hypertrophy, inflammatory cell infiltration and tyrosine hydroxylase expression, used as marker of sympathetic activity. Ang II caused a significant increase of blood pressure, myocardial interstitial and perivascular fibrosis and myocardial hypertrophy, as compared to control groups. C21 or Ang 1-7 administration did not modify the increase in blood pressure in Ang II treated rats, but both prevented the development of myocardial fibrosis and hypertrophy. Treatment with losartan blocked the onset of hypertension and myocardial fibrosis and hypertrophy in Ang II treated rats. Activation of AT2 receptors or Mas receptors prevents the onset of myocardial fibrosis and hypertrophy in Ang II-dependent hypertension through the reduction of myocardial inflammatory cell infiltration and tyrosine hydroxylase expression. Unlike what happens in case of treatment with losartan, the antifibrotic and antihypertrophic effects that follow the activation of the AT2 or Mas receptors are independent on the modulation of blood pressure.

BACKGROUND: Treatment of hip fractures during the coronavirus disease 2019 (COVID-19) pandemic has posed unique challenges for the management of COVID-19-infected patients and the maintenance of standards of care. The primary endpoint of this study is to compare the mortality rate at 1 month after surgery in symptomatic COVID-positive patients with that of asymptomatic patients. A secondary endpoint of the study is to evaluate, in the two groups of patients, mortality at 1 month on the basis of type of fracture and type of surgical treatment. MATERIALS AND METHODS: For this retrospective multicentre study, we reviewed the medical records of patients hospitalised for proximal femur fracture at 14 hospitals in Northern Italy. Two groups were formed: COVID-19-positive patients (C+ group) presented symptoms, had a positive swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and received treatment for COVID-19; COVID-19-negative patients (C- group) were asymptomatic and tested negative for SARS-CoV-2. The two groups were compared for differences in time to surgery, survival rate and complications rate. The follow-up period was 1 month. RESULTS: Of the 1390 patients admitted for acute care for any reason, 477 had a proximal femur fracture; 53 were C+ but only 12/53 were diagnosed as such at admission. The mean age was > 80 years, and the mean American Society of Anesthesiologists (ASA) score was 3 in both groups. There was no substantial difference in time to surgery (on average, 2.3 days for the C+ group and 2.8 for the C- group). As expected, a higher mortality rate was recorded for the C+ group but not associated with the type of hip fracture or treatment. No correlation was found between early treatment (< 48 h to surgery) and better outcome in the C+ group. CONCLUSIONS: Hip fracture in COVID-19-positive patients accounted for 11% of the total. On average, the time to surgery was > 48 h, which reflects the difficulty of maintaining normal workflow during a medical emergency such as the present pandemic and notwithstanding the suspension of non-urgent procedures. Hip fracture was associated with a higher 30-day mortality rate in COVID-19-positive patients than in COVID-19-negative patients. This fact should be considered when communicating with patients and/or their family. Our data suggest no substantial difference in hip fracture management between patients with or without COVID-19 infection. In this sample, the COVID-19-positive patients were generally asymptomatic at admission; therefore, routine screening is recommended. LEVEL OF EVIDENCE: Therapeutic study, level 4.

BACKGROUND: Periprosthetic fractures (PPFs) are a growing matter for orthopaedic surgeons, and patients with PPFs may represent a frail target in the case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The purpose of this study is to investigate whether hospital reorganisations during the most severe phase of the SARS-CoV-2 pandemic affected standards of care and early outcomes of patients treated for PPFs in Northern Italy. MATERIALS AND METHODS: Data were retrieved from a multicentre retrospective orthopaedics and traumatology database, including 14 hospitals. The following parameters were studied: demographics, results of nasopharyngeal swabs, prevalence of coronavirus disease 2019 (COVID-19), comorbidities, general health status (EQ-5D-5L Score), frailty (Clinical Frailty Scale, CFS), pain (visual analogue scale, VAS), anaesthesiologic risk (American Society of Anaesthesiology Score, ASA Score), classification (unified classification system, UCS), type of operation and anaesthesia, in-hospital and early complications (Clavien-Dindo Classification, CDC), and length of stay (LOS). Data were analysed by means of descriptive statistics. Out of 1390 patients treated for any reason, 38 PPFs were included. RESULTS: Median age was 81 years (range 70-96 years). Twenty-three patients (60.5%) were swabbed on admission, and two of them (5.3%) tested positive; in three patients (7.9%), the diagnosis of COVID-19 was established on a clinical and radiological basis. Two more patients tested positive post-operatively, and one of them died due to COVID-19. Thirty-three patients (86.8%) presented a proximal femoral PPF. Median ASA Score was 3 (range, 1-4), median VAS score on admission was 3 (range, 0-6), median CFS was 4 (range, 1-8), median EQ-5D-5L Score was 3 in each one of the categories (range, 1-5). Twenty-three patients (60.5%) developed post-operative complications, and median CDC grade was 3 (range, 1-5). The median LOS was 12.8 days (range 2-36 days), and 21 patients (55.3%) were discharged home. CONCLUSIONS: The incidence of PPFs did not seem to change during the lockdown. Patients were mainly elderly with comorbidities, and complications were frequently recorded post-operatively. Despite the difficult period for the healthcare system, hospitals were able to provide effective conventional surgical treatments for PPFs, which were not negatively influenced by the reorganisation. Continued efforts are required to optimise the treatment of these frail patients in the period of the pandemic, minimising the risk of contamination, and to limit the incidence of PPFs in the future. LEVEL OF EVIDENCE: IV.

The specific etiology of meniscal tears, including the mechanism of lesion, location, and orientation, is considered for its contribution to subsequent joint cytokine responsiveness, healing outcomes, and by extension, appropriate lesion-specific surgical remediation. Meniscal repair is desirable to reduce the probability of development of posttraumatic osteoarthritis (PTOA) which is strongly influenced by the coordinate generation of pro- and anti-inflammatory cytokines by the injured cartilage. We now present biochemical data on variation in cytokine levels arising from two particular meniscal tears: bucket-handle (BH) and posterior horn (PH) isolated meniscal tears. We selected these two groups due to the different clinical presentations. We measured the concentrations of TNF-α, IL-1ß, IL-6, IL-8, and IL-10 in knee synovial fluid of 45 patients with isolated meniscal lesions (BH tear, n = 12; PH tear, n = 33). TNF-α levels were significantly (p < 0.05) greater in the BH group compared with the PH group, whereas IL-1ß levels were significantly greater (p < 0.05) in the PH group compared with the BH group. Both BH and PH groups were consistent in presenting a positive correlation between concentrations of IL-6 and IL-1ß. A fundamental difference in IL-10 responsiveness between the two groups was noted; specifically, levels of IL-10 were positively correlated with IL-6 in the BH group, whereas in the PH group, levels of IL-10 were positively correlated with IL-1ß. Collectively, our data suggest a possible influence of the meniscal tear pattern to the articular cytokine responsiveness. This differential expression of inflammatory cytokines may influence the risk of developing PTOA in the long term.

BACKGROUND: A significant increase in the prevalence of intracapsular femoral neck fractures in the elderly population was reported but the best treatment is still debated. AIM: To evaluate the mortality rate and the reoperation rate of stable neck fractures treated with cannulated screw fixation in elderly patients. METHODS: This was a retrospective study of patients older than 60 years with a Garden I or II femoral neck fractures treated with cannulated screw fixation without capsulotomy. A total of 244 patients (246 hips) who underwent surgery between 2008 and 2018 were included. The average age at the time of surgery was 80 years (range 60-99 years). The mean ASA score was 2.64 (range 1-4). Mortality rate, complications, reoperation rate, the time elapsed between surgeries were recorded. RESULTS: The mortality rate was 50.0%. There were 16 mortalities (6.6%) in the first-month follow-up. We observed higher mortality rates in ASA 4 (80.8%). In 22 patients (8.9%), complications after surgery were observed, and in 11 patients (4.5%) underwent conversion surgery to hemiarthroplasty at a mean of 14.6 months (range 2-48 months) after the femoral screw fixation. Two patients were treated with hardware removal and Gamma Nail for a peri-implant subtrochanteric femur fracture. INTERPRETATION: Cannulated screw fixation should be considered a valid option in intraarticular femoral Garden I-II fractures in elderly patients. LEVEL OF EVIDENCE: Level IV, therapeutic study.

BACKGROUND: In children, fracture non-union is uncommon yet, curiously, non-union of distal fibula fractures are rarely reported. Historically, the most common treatment of a lateral malleolus fracture after an ankle sprain is conservative, which usually leads to fracture union. However, even in clinically stable ankles, subsequent pain arising from fracture site could suggest non-union, thereby necessitating reexamination and possible secondary treatment. CASE PRESENTATION: We report the case of an 8-year-old girl with an epiphyseal distal fibula fracture complicated with a symptomatic non-union associated with the chondral flap of the talar dome after conservative treatment. Surgical excision of the fragment and chondroplasty was performed and resulted in an excellent clinical outcome. CONCLUSION: This case report illustrates the necessity of particularly meticulous evaluation of pediatric post-traumatic ankle pain. Surgical treatment as well as talar chondral evaluation should be taken into consideration in the treatment of pediatric distal fibular nonunion.

INTRODUCTION: Ideal treatment of acute acromioclavicular joint (ACJ) dislocation remains unresolved. We evaluated ACJ reconstruction using polyester tapes and temporary Kirschner wire (KW) and presented clinical and radiological outcomes. MATERIALS AND METHODS: Patients were retrospectively evaluated and classified according to Rockwood classification, clinical and sportive characteristics. Constant Score (CS) and ACJ joint instability (ACJI) score were collected. Zanca's, Alexander, axillary, standard, and stress AP views were collected. Radiographic coracoclavicular distance (CCd) of healthy and injured shoulders was measured pre-operatively, at 3 months and at minimum 2-year follow-up. Heterotopic ossifications and clavicular osteolysis were evaluated. Influence of patients' characteristics and AC joint type on clinical and radiological outcomes were determined. RESULTS: Sixteen patients (13 type V and 3 type III ACJ dislocation) reached the end of follow-up (mean 2.4 years; range 22-72 months). Mean CS was 99.63 (range 96-100), while the mean ACJI score was 96.19 (range 85-100). The CCd of the treated shoulder was comparable with the healthy shoulder at 3 months and at last follow-up; moreover, there was no difference in CCd scores at 3 months and at 2 years. CCd scores were lower in sedentary patients compared with physically active (sporty) patients. Heterotopic ossifications were observed in three patients. No osteolysis was reported. CONCLUSION: This technique provides good results with few complications and should be considered as an effective method to treat ACJ acute dislocation. CCd scores correlate with overuse factors but not with other clinical scores.

OBJECTIVE: To evaluate the efficacy of a rehabilitation programme including balance task-specific training in improving physical function, pain, activities of daily living (ADL), balance and quality of life in subjects after a hip fracture. DESIGN: Randomized controlled trial. SUBJECTS: A total of 52 older subjects selected for internal fixation due to extra-capsular hip fracture were randomized to be included in an experimental ( n = 26) and control group ( n = 26). INTERVENTIONS: The experimental group underwent a rehabilitation programme based on balance task-specific training. The control group underwent general physiotherapy, including open kinetic chain exercises and walking training. Both groups individually followed programmes of 90-minute sessions five times/week for three weeks. OUTCOME MEASURES: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a Pain Numerical Rating Scale, the Berg Balance Scale, the Functional Independence Measure and the 36-item Short-Form Health Survey. The participants were evaluated before and after training, and after 12 months. RESULTS: Significant effects of time, group and time × group were found for all outcome measures in favour of the experimental group. A clinically important between-group difference of 25 points was achieved after training and at follow-up in terms of the primary outcome (WOMAC function before treatment, after treatment and at follow-up was 84.8 (3.7), 39.8 (4.9) and 35.7 (6.2) for the experimental group and 80.9 (5.7), 65.2 (7.1) and 61.0 (11.1) for the control group). CONCLUSION: An inpatient rehabilitation programme based on balance task-specific training is useful in improving physical function, pain, ADL and quality of life in older patients after hip fracture.

The treatment of anterior cruciate ligament (ACL) injuries in children and adolescents is challenging. Preclinical and clinical studies investigated ACL repairing techniques in skeletally immature subjects. However, intra-articular bioenvironment following ACL tear has not yet been defined in skeletally immature patients. The aim of this study was to measure cytokine concentrations in the synovial fluid in adolescent population. Synovial levels of IL-1ß, IL-1ra, IL-6, IL-8, IL-10, and TNF-α were measured in 17 adolescent patients (15 boys) with ACL tears who underwent ACL reconstruction including acute (5), subacute (7), and chronic (5) phases. Femoral growth plates were classified as "open" in three patients, "closing" in eight, and "closed" in six. Eleven patients presented an ACL tear associated with a meniscal tear. The mean Tegner and Lysholm scores (mean ± SD) of all patients were 8 ± 1 and 50.76 ± 26, respectively. IL-8, TNF-α, and IL-1ß levels were significantly greater in patients with "open" physes. IL-1ra and IL-1ß levels were significantly higher in patients with ACL tear associated with a meniscal tear. Poor Lysholm scores were associated with elevated IL-6 and IL-10 levels. IL-10 levels positively correlated with IL-6 and IL-8 levels, whereas TNF-α concentration negatively correlated with IL-6 levels. Skeletally immature patients with meniscal tears and open growth plates have a characteristic cytokine profile with particularly elevated levels of proinflammatory cytokines including IL-8, TNF-α, and IL-1ß. This picture suggests that the ACL tear could promote an intra-articular catabolic response in adolescent patients greater than that generally reported for adult subjects. The study lacks the comparison with synovial samples from healthy skeletally immature knees due to ethical reasons. Overall, these data contribute to a better knowledge of adolescent intra-articular bioenvironment following ACL injuries.

Marcello Malpighi (1628-1694), who is referred to as the father of microscopical anatomy, histology, physiology and embryology was an Italian biologist and physician, well known for his discoveries on microscopical anatomy of kidney, circulating and lymphatic systems. As well as being a brilliant anatomist, Malpighi was also a valued physician so far as to became the personal physician of Pope Innocent XII (1615-1700). On 23 August 1691, one month after his election, the Pope fell to the ground hitting his left hip. Malpighi, as his personal physician, was immediately called and diagnosed a hip fracture. At that time fractures were generally treated by surgeons, barbers and sawbones, while physicians were mainly concerned with internal diseases. Despite that, Marcello Malpighi cured Pope Innocent XII's hip fracture by applying some modern traumatologic concepts. This article analyses how Malpighi treated this hip fracture, comparing it with the current approach.

Hip fracture is a common occurrence in the elderly. Due to the growing demand for the specific care of these patients, we established the Orthogeriatric Unit (OGU) at San Gerardo University Hospital (Italy) in 2007. However, simultaneous bilateral femoral neck fractures among the geriatric population (those aged ≥65 years) are rarely reported in the literature. Reporting the rare case of a frail 76-year-old woman admitted with bilateral hip fracture and end-stage renal disease, we explain the important role played by the OGU and its flexible multidisciplinary approach for providing comprehensive care to patients with multimorbidity and clinical complexity. The team of geriatricians, orthopedic surgeons, anesthesiologists, and, in this case, a nephrologist, helped in the careful planning and timing of the single-step surgical repair, decided the appropriate type of anesthesia, and optimized outcomes. After a prompt evaluation of the patient, the OGU approach can achieve clinical stabilization prior to intervention. Along with a strict follow-up in the postoperative phase, this could result in a significant reduction of complications and mortality rates and an early start to a tailored rehabilitation process. We strongly suggest employing facilities with multidisciplinary teams for cases involving complex patients at short-term high risk for poor clinical outcomes. Indeed, the usual single-specialist model of care is gradually being abandoned worldwide.

BACKGROUND: Age is one of the most robust risk factors for hip fracture. Recent projections indicate that almost half of hip fractures are occurring with an increasing trend among the "oldest old" (i.e., in those aged >85 years). AIMS: To compare clinical characteristics, outcomes, and risk factors for 6-month mortality in two groups of "oldest old" patients (group 1 = 85-89, group 2 > 90 years), after hip fracture surgery. METHODS: Observational prospective cohort study with 6-month follow-up, performed in an Orthogeriatric Unit of an academic hospital between March 2007 and November 2012. RESULTS: Two hundred seventy-five patients (group 1: N = 171; group 2: N = 104) underwent a comprehensive geriatric assessment, including demographics, clinical, functional, nutritional, and mental status. The 6-month rehospitalization and mortality rates after surgery were assessed through structured telephone interviews with patient's caregivers. Multivariate logistic regression models were used to evaluate predictors of 6-month mortality, adjusting for relevant covariates. Fifty-eight patients died at follow-up. The in-hospital and 6-month mortality rates were significantly higher for patients of group 2 than for those of group 1. After adjusting for covariates, the multivariate logistic regressions showed that severe disability (OR 2.24, 95 % CI 1.08-4.65) and postoperative delirium (POD) (OR 3.80, 95 % CI 1.72-8.39) were predictors of 6-month mortality. CONCLUSIONS: Patients aged >90 years who underwent hip fracture surgery are more likely to die at 6 months than those aged 85-89 years. Pre-fracture disability and POD are predictors of this excess of mortality.

OBJECTIVE: To evaluate the efficacy of an in-hospital programme based on task-oriented exercises associated with early full weight-bearing in patients with multiple comorbidities undergoing total hip replacement. DESIGN: Randomized controlled trial. SETTING: Specialised rehabilitation centre. SUBJECTS: A total of 100 patients (mean age of 69 (8) years; 40 males, 60 females). INTERVENTIONS: The experimental group underwent task-oriented exercises and was encouraged to abandon any walking aids by the end of their in-hospital stay. The control group underwent open chain kinetic exercises, and was recommended to use partial weight-bearing and walking aids until three months after surgery. Both groups individually followed programmes of 90-minute sessions five times a week for three weeks. OUTCOME MEASURES: Western Ontario and McMaster Universities Osteoarthritis Index, Pain Numerical Rating Scale, Functional Independence Measure, and Short-Form Health Survey. The participants were evaluated before, after training, and after a further 12 months. RESULTS: There were no significant between-group differences at baseline. After training, a between-group difference of 12 points was found for the Western Ontario and McMaster Universities Osteoarthritis Index - functional subscale, indicating a clinically tangible treatment effect on disability. The Functional Independence Measure increased by 31 and 15 points in the experimental and control group, respectively. A linear mixed model revealed significant effects of time, group, and time by group interaction on disability, pain, activities of daily living, and most of the physical quality of life domains. CONCLUSION: Task-oriented exercises associated with early full weight-bearing improve disability, pain, activities of daily living, and quality of life after total hip replacement.

Purpose: Anterior cruciate ligament repair techniques are of growing interest because they allow for minimally invasive surgery that avoids harvesting of the transplant, without risking growth deficiencies in young patients. The aim of this study is to summarize the published evidence about arthroscopic repair of anterior cruciate ligament proximal tears in skeletally immature patients. Methods: In total, four studies were included and processed for data extraction after screening for eligibility for this systematic review: one retrospective cohort study and three retrospective case series. Altogether, the four studies included in this review included 61 skeletally immature patients with a mean age of 12.1 years diagnosed with proximal anterior cruciate ligament tear who underwent arthroscopic repair with preservation of the native ligament. The mean follow-up period was 2.8 years. Results: The most relevant and objective outcome that we considered was re-rupture rate. One study reports a cumulative incidence of graft failure in the first 3 years after surgery of 48.8% while the others report a 0%, 0% and 21.5% re-rupture rate. No growth disturbances were reported in the included studies. Conclusion: Despite growing interest surrounding anterior cruciate ligament repair techniques, the presence of limited quality studies in the literature means repair cannot be strongly supported at present. Some encouraging data regarding the absence of growth disturbance and functional outcomes does exist, but studies with larger samples are required. Level of evidence: level IV.
