Chronic kidney disease and orthostatic hypotension in hospitalised older adults.

PURPOSE: Orthostatic hypotension (OH) may predispose older adults to health complications leading to functional impairment. Despite the central role of the kidney in blood pressure control, the contribution of renal function in orthostatic hypotension is poorly investigated. To verify the association between Chronic Kidney Disease (CKD) and OH a population of hospitalised elderly patients with comorbidities was studied. MATERIALS AND METHODS: 174 patients were consecutively admitted to Acute Geriatric Wards. On admission, patients underwent postural systolic (SBP) and diastolic (DBP) blood pressure evaluation by automatic oscillometric device after 10 min rest in lying position, and in standing position at time 0, 1, 3 and 5 min. CKD was assumed for estimated glomerular filtration rate (e-GFR) less than 60 mL/min/1.73 m2. RESULTS: The mean age of the population enrolled was 74.4 ± 7.0. OH was found in 46.0% and CKD in 56.3% of patients, respectively. A lower e-GFR was observed in patients with (56.1 ± 16.7 mL/min/1.73 m2) than in those without OH (61.1 ± 15.9 mL/min/1.73 m2) (p < 0.05). A greater fall in SBP at 0-min (12.8 ± 6.3 vs. 7.7 ± 3.2 mmHg) and at 1-min (8.4 ± 4.5 vs. 5.7 ± 2.8 mmHg) was found in CKD patients in respect to patients without CKD during active standing test (p < 0.05). Similarly, a DBP reduction at 0-min and at 1-min was observed in CKD patients in respect to patients without CKD (p < 0.05). A multivariate logistic regression analysis showed that CKD was associated to OH (OR 2.426; 95%CI 1.192-4.937; p = 0.014). CONCLUSIONS: CKD is associated to OH in hospitalised older adults.

The Role of Patient Position in the Surgical Treatment of Supracondylar Fractures of the Humerus: Comparison of Prone and Supine Position.

Background and Objectives: Supracondylar fractures of the humerus (SCHF) make up about one-third of pediatric fractures and are the most common elbow fractures in children. Reduction and fixation of SC fractures can be performed with the patient in the prone or supine position. However, the role of the patient's position during surgery is still unclear. The purpose of this systematic review is to evaluate, based on data from the literature, the role of patient position during closed reduction and fixation of pediatric SCHFs. Materials and Methods: A systematic review of the current literature from 1951 to 2021 was conducted according to PRISMA guidelines. Articles were identified from 6 public databases. Articles were screened and abstracted by two investigators and the quality of included publications (n = 14) was assessed (MINORS criteria). Statistical analyses were performed using R studio 4.1.2. Results: The systematic literature review identified 114 articles, from which, according to inclusion and exclusion criteria, 14 studies were identified. A total of 741 children were treated in the prone position and 538 in the supine position. The results of the systematic review showed that there were no statistical differences between the two positions with regard to clinical, radiographic, and complication outcomes. Conclusions:: The functional and radiographic outcome of displaced SCHFs is generally excellent regardless of the position, prone or supine, in which the patient is positioned for surgery. The choice of how to position the patient depends on the habit and experience of the surgeon and anesthesiologist performing the surgery.

Reliability of fr-AGILE tool to evaluate multidimensional frailty in hospital settings for older adults with COVID-19.

AIMS: The study assesses the reliability of fr-AGILE, a validated rapid tool used for the evaluation of multidimensional frailty in older adults hospitalized with COVID-19. METHODS: Two different staff members independently assessed the presence of frailty in 144 patients aged ≥ 65 years affected by COVID-19 using the fr-AGILE tool. The internal consistency of fr-AGILE was evaluated by examining the item-total correlations and the Kuder-Richardson (KR) formula. The inter-rater reliability was evaluated using linear weighted kappa. RESULTS: Multidimensional frailty severity increases with age and is associated to higher use of non-invasive ventilation (p = 0.025), total severity score on chest tomography (p = 0.001) and in-hospital mortality (p = 0.032). Fr-AGILE showed good internal consistency (KR-20 = 0.742) and excellent inter-rater reliability (weighted kappa = 0.752 and 0.878 for frailty score and frailty degree, respectively). CONCLUSIONS: fr-AGILE tool can quickly identify and quantify multidimensional frailty in hospital settings for older patient affected by COVID-19.

Outcome of permanent pacemaker implantation in transcatheter or surgical aortic valve replacement: A still unsolved problem.

Despite advances in technologies and clinical experience, conduction disorders, after transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR), represent the weak point of these procedures, requiring permanent pacemaker implantation (PPI) till 37.7% of patients in TAVR recipients. The role of PPI in TAVR and SAVR remains controversial in mid- and long-term outcomes. Indeed, many studies have been published with contradictory results, leaving doubts rather than certainties.

Neutrophil to lymphocyte ratio predicts permanent pacemaker implantation in TAVR patients.

INTRODUCTION: In this prospective multicenter analysis, we aimed to investigate the predictive role of neutrophil/lymphocyte ratio (NLR) in permanent pacemaker implantation (PPI) in patients undergoing transcatheter aortic valve replacement (TAVR). MATERIALS AND METHODS: One hundred and seventy-nine consecutive patients without previous PPI underwent TAVR from February 2017 to September 2021. Patients were further divided based on presence (n = 48) and absence of conduction abnormalities (CAs) at hospital admission (n = 131). RESULTS: In patients with previous CAs, NLR values did not differ significantly between patients requiring PPI (n = 16, 33%) and those not requiring it. In contrast, in patients with no CAs at hospital admission, NLR values measured at admission and on TAVR day were significantly higher in patients requiring PPI (n = 17, 13%) (4.07 ± 3.22 vs. 3.01 ± 1.47, p = .025, and 10.81 ± 7.81 vs. 5.84 ± 3.78, p = .000, respectively). Multivariable analysis showed that NLR at TAVR day was an independent predictor of PPI in patients without CAs (OR 1.294; 95% CI 1.028-1.630; p = .028), but not in those with previous CAs. ROC curve analysis showed that the cut point was a NLR value of >7.25. Time to PPI was delayed till 21 days in patients without CAs. CONCLUSIONS: In this prospective study, higher NLR values on the day of TAVR day were associated with an increased PPI rate in patients undergoing TAVR with no previous CAs. It is advisable, being inflammation part of the process, to prolong the time of observation for all patients without CAs till at least 21 days not to miss any new CA necessitating PPI.

Advanced Technologies to Target Cardiac Cell Fate Plasticity for Heart Regeneration.

The adult human heart can only adapt to heart diseases by starting a myocardial remodeling process to compensate for the loss of functional cardiomyocytes, which ultimately develop into heart failure. In recent decades, the evolution of new strategies to regenerate the injured myocardium based on cellular reprogramming represents a revolutionary new paradigm for cardiac repair by targeting some key signaling molecules governing cardiac cell fate plasticity. While the indirect reprogramming routes require an in vitro engineered 3D tissue to be transplanted in vivo, the direct cardiac reprogramming would allow the administration of reprogramming factors directly in situ, thus holding great potential as in vivo treatment for clinical applications. In this framework, cellular reprogramming in partnership with nanotechnologies and bioengineering will offer new perspectives in the field of cardiovascular research for disease modeling, drug screening, and tissue engineering applications. In this review, we will summarize the recent progress in developing innovative therapeutic strategies based on manipulating cardiac cell fate plasticity in combination with bioengineering and nanotechnology-based approaches for targeting the failing heart.

Validation of "(fr)AGILE": a quick tool to identify multidimensional frailty in the elderly.

BACKGROUND: Several tools have been proposed and validated to operationally define frailty. Recently, the Italian Frailty index (IFi), an Italian modified version of Frailty index, has been validated but its use in clinical practice is limited by long time of administration. Therefore, the aim of this study was to create and validate a quick version of the IFi (AGILE). METHODS: Validation study was performed by administering IFi and AGILE, after a Comprehensive Geriatric Assessment (CGA) in 401 subjects aged 65 or over (77 ± 7 years). AGILE was a 10-items tool created starting from the more predictive items of the four domains of frailty investigated by IFi (mental, physical, socioeconomic and nutritional). AGILE scores were stratified in light, moderate and severe frailty. At 24 months of follow-up, death, disability (taking into account an increase in ADL lost ≥1 from the baseline) and hospitalization were considered. Area under curve (AUC) was evaluated for both IFi and AGILE. RESULTS: Administration time was 9.5 ± 3.8 min for IFi administered after a CGA, and 2.4 ± 1.2 min for AGILE, regardless of CGA (p < 0.001). With increasing degree of frailty, prevalence of mortality increased progressively from 6.5 to 41.8% and from 9.0 to 33.3%, disability from 16.1 to 64.2% and from 22.1 to 59.8% and hospitalization from 17.2 to 58.7% and from 27.0 to 52.2% with AGILE and IFi, respectively (p = NS). Relative Risk for each unit of increase in AGILE was 56, 44 and 24% for mortality, disability and hospitalization, respectively and was lower for IFi (8, 7 and 4% for mortality, disability and hospitalization, respectively). The AUC was higher in AGILE vs. IFi for mortality (0.729 vs. 0.698), disability (0.715 vs. 0.682) and hospitalization (0.645 vs. 0.630). CONCLUSIONS: Our study shows that AGILE is a rapid and effective tool for screening multidimensional frailty, able to predict mortality, disability and hospitalization, especially useful in care settings that require reliable assessment instruments with short administration time.

Type 2 myocardial infarction: is it a geriatric syndrome?

Type 2 myocardial infarctions (T2-MI) is a type of necrosis that results from reduced oxygen supply and/or increased demand secondary to other causes unrelated to acute coronary atherothrombosis. The development and implementation of sensitive and high-sensitivity cardiac necrosis marker and the age-related increase of comorbidity lead to a boost of the frequency of T2-MI. T2-MI is often a complication of a high degree of clinical frailty in older adults, emerging as a "geriatric syndrome". Age-related non-cardiovascular causes may be the triggering factors and are strongly associated with the diagnosis, treatment, and prognosis of T2-MI. To date, there are no guidelines on management of this pathology in advancing age. Patient-centered approach and comprehensive geriatric assessment play a key role in the diagnosis, therapy and prognosis of geriatric patients with T2-MI.

Permanent atrial fibrillation and pulmonary embolism in elderly patients without deep vein thrombosis: is there a relationship?

BACKGROUND AND AIM: Permanent Atrial Fibrillation (pAF) is associated with increased risk of embolic complications. The relationship between pAF and pulmonary embolism (PE) has not been extensively investigated in elderly patients. Here, we aim at verifying whether pAF is associated to an increased risk of PE in a cohort of elderly patients with and without Deep Vein Thrombosis (DVT). METHODS: 235 patients older than 65 years with PE with or without pAF were retrospectively enrolled and stratified by the absence or presence of DVT. The diagnosis of PE was performed by computed tomography angiography (CTA). Right echocardiographic parameters were monitored. The severity of PE was evaluated by CTA quantization (PE score = 1, involvement of main branches of pulmonary artery) and by dimer-D (> 3000 µg/L). RESULTS: DVT was identified only in 51 cases of PE (21.7%). pAF prevalence was higher in PE without than in those with DVT (64.9% vs. 35.1%, p < 0.01). PE severity was more evident in pAF patients without than in those with DVT. Multivariate analysis of the role of pAF on PE severity confirms these results (RR = 3.41 for PE score = 1, and 8.55 for dimer-D > 3000 µg/L). CONCLUSIONS: We conclude that in elderly patients with PE, the prevalence of pFA was doubled, in the absence of DVT, and it is associated with a more severe PE in the absence than in the presence of DVT. Thus, in the absence of DVT, pFA should be considered as cause of PE.

Bone mineral density as a marker of hip implant longevity: a prospective assessment of a cementless stem with dual-energy X-ray absorptiometry at twenty years.

PURPOSE: Bone remodeling around the femoral component after total hip arthroplasty (THA) is considered to be an important factor in long-term stability and seems to be strictly related to the stem design, coating, and fixation. Stress shielding, micro-movement, and high intra-articular fluid pressure might activate macrophages and osteoclasts, causing progressive bone density decreases. Here we analyze the bone mineral density (BMD) around a cementless femoral stem during a 20-year period to better understand the adaptive bone changes around such implants during long-term follow-up. METHODS: In this retrospective study, 14 patients treated by THA were reviewed from a cohort of 84. Clinical evaluation with Harris Hip Score and radiographic assessment were performed throughout a 20-year follow-up. To evaluate the bone remodeling around the stem, we monitored the femoral BMD in four regions of interest with a dual-energy X-ray absorptiometry (DEXA) post-operatively and at one, two, three, five and 20 years of follow-up. RESULTS: The main BMD changes between the post-operative examination and the 20-year follow-up varied between + 11.19% and + 24.30%. Patients with signs of loosening, low Harris Hip Scores, and pain showed decreasing BMD values. CONCLUSIONS: The correlation between the clinical result and BMD values could suggest DEXA results as a predictor of implant loosening or longevity.

Negative prognostic factors in surgical treatment for trimalleolar fractures.

PURPOSE: Trimalleolar fractures are a common injury of the ankle that require surgical treatment to obtain an anatomic reduction of both malleoli and stabilization of the syndesmosis. This study aims to report the outcomes of surgical treatment for trimalleolar fractures, identifying the risk factors determining a worse result. MATERIALS AND METHODS: Between January 2013 and December 2016, 48 patients with trimalleolar fracture treated with open reduction and internal fixation were retrospectively analyzed. The mean age was 44.69 years, and average body mass index (BMI) was 29.04. According to the Danis-Weber classification, 30 (62.5%) fractures were type B and 18 (37.5%) were type C. Clinical and radiographic evaluations at 3, 6, and 12 months were assessed. The functional results of Visual Analogue Staircases and Olerud-Molander (O&M) ankle score were reported. RESULTS: No significant difference was found among the size of the PM in patients with and without ankle dislocation (p = 0.364). Therefore, there is no correlation between the size of the posterior fragment and the ankle dislocation and the size of the posterior malleolus and syndesmosis stability (p = 0.328). Age over 61 years, BMI > 40, ASA > 1, type C fracture, and fracture dislocation were considered as negative prognostic fractures. CONCLUSIONS: Surgical treatment for trimalleolar fractures needs accurate preoperative planning. Age over 61 years, BMI > 40, ASA > 1, type C fracture, and fracture dislocation were considered as negative prognostic fractures.

Acute care hospital at different levels of intensity: the role of Geriatrician.

The traditional model of care is based on "disease-centered" management that requires the organization of the hospital in specialized wards, to which the patient is assigned for the main disease. The growing need to optimize economical and human resources and to promote a global approach to the patient has led to the setting up of the intensity of care model. It is a health system based on a "patient-centered" approach, where the hospital is organized in departments dedicated to patients with homogenous needs of care. In Italy, intensity of care model is currently being tested in the hospital organization, where three levels of intensity are proposed: low, medium and high. The purpose of the following review is to describe the role and importance of the Geriatrician in each of these care settings and to highlight the contradiction of a National Health System which promotes the geriatric approach to all types of patients, but does not invest in the formation and integration of the figure of the Geriatrician in clinical practice, condemning it to marginalization or even extinction.

The reverse metabolic syndrome in the elderly: Is it a "catabolic" syndrome?

Traditional risk factors of cardiovascular death in the general population, including body mass index (BMI), serum cholesterol, and blood pressure are also found to relate to outcomes in the geriatric population, but in a differing direction. A higher body mass index, hypercholesterolemia and hypertension are not harmful but even permit better survival at advancing age. This phenomenon is called "reverse epidemiology" or "risk factor paradox" and is also detected in a variety of chronic disease states such as chronic heart failure. Accordingly, a low BMI, blood pressure and cholesterol values are associated with a worse prognosis. Several possible causes are hypothesized to explain this elderly paradox, but this phenomenon remains controversial and its underlying reasons are poorly understood. The aim of this review is to recognize the factors behind this intriguing phenomenon and analyse the consequences that it can bring in the management of the cardiovascular therapy in elderly patient. Finally, a new phenotype identified as "catabolic syndrome" has been postulated.

Surgical treatment for symptomatic non-ossifying fibromas of the lower extremity with calcium sulfate grafts in skeletally immature patients.

BACKGROUND: Non-ossifying fibromas (NOFs) are common benign bone lesions found in children and adolescents. They usually involve metaphysis of long bones, tend to gradually disappear with age and usually do not require surgery, while they are not associated with pathological fractures. The aim of this study was to evaluate the outcome and efficacy of a single-stage procedure, comprising curettage of the lesion and calcium sulfate pellet (CaSP) grafting, in skeletally immature patients with large, symptomatic NOF of the lower extremity, and the possible limitations of the procedure. METHODS: Nine skeletally immature patients with symptomatic NOF of the lower extremity were treated between 2013 and 2016. Details of age, history of presentation, location and size (in mm) of the lesion, histology and follow-up details were recorded. Lesions were classified in Ritschl radio-morphological stages. CaSP integration was assessed by Irwing's classification. The average size of lesions was 54.6 mm in length (range 31-95). All lesions were symptomatic. The average bone expansion in relation to the bone diameter was 67.4% in the transversal plane (range 31-100) and 77.8% in the sagittal plane (range 55-100). Mean patient age at time of treatment was 9.8 years (range 7-14); mean follow-up was 2 years (range 2-4). All the patients were symptomatic, and 8 out of 9 (89%) NOFs were Ritschl type B. All the patients were treated surgically with a single-step approach, as described. RESULTS: On average, 86 mL of CaSPs was used per case (range 10-250). None of the patients required internal fixation. At last follow-up visit, CaSPs were fully incorporated in all the patients according to Irwing's classification (Stage 3). No serous drainage from wounds was recorded in any of the patients. No cases of pathological fracture, bone deformity, growth arrest or growth disturbance or infection were observed. At last follow-up visit, all the patients had resumed full sport and daily life activities. CONCLUSIONS: CaSPs offer a safe, cheap, convenient alternative to the autograft as an implant substitute that helps regeneration of bone in the defects produced by curettage of large, symptomatic NOFs. Chemical cauterization of bone walls does not interfere with CaSP integration into bone tissue.

Potential presence of metals in patients treated with metal-metal coupling prostheses for hip arthroplasty at 7 and 10 years of follow-up.

BACKGROUND: Beginning in 2008, metal-on-metal prostheses have been in the spotlight owing to much higher revision rates than expected. Adverse local tissue reactions have been well described in the literature as potential complications. METHODS: Between 2012 and 2013, 13 patients with metal-on-metal total hip replacements were evaluated clinically and radiologically and with laboratory samples. The same tests were repeated between 2015 and 2016 on eight patients to assess any changes. In the laboratory assessment, we searched for chromium, cobalt, molybdenum, and nickel in blood and urine samples over 24 h. RESULTS: Clinical assessment has shown good score in all patients except one. On a second examination, between 2015 and 2016, all patients obtained results similar to those obtained in the first assessment, except a patient, who reported a recent fall. In the radiological assessment between 2012 and 2013, results were optimal, apart from a case of aseptic mobilization. The patients reassessed 3 years after the first examination showed radiological results similar to those previously obtained, apart from a patient, who showed signals of mobilization. Metal levels found in their blood decreased in most cases after 3 years. Urine levels of nickel increased in five subjects, and chromium levels increased in four, but levels of cobalt and molybdenum decreased in four patients. CONCLUSION: It could be hypothesized that the decreasing trend of metal ion levels is associated with a stable wear status. On the contrary, a progressive increase in metal ion levels must be considered as early proof of implant loosening.

Chronic obstructive pulmonary disease and long-term mortality in elderly subjects with chronic heart failure.

BACKGROUND: Chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are associated with high rates of mortality in elderly subjects. Concurrent CHF and COPD frequently occur, especially in with advancing age. This study examines long-term mortality in community-dwelling elderly subjects affected by CHF alone, COPD alone, and coexistent CHF and COPD. METHODS: The study evaluated 12-years mortality in 1288 subjects stratified for the presence or absence of CHF or COPD alone, and for coexistence of CHF and COPD. RESULTS: Mortality, at 12 year follow-up, was 46.7% overall, 68.6% in the presence of CHF alone (p < 0.001), 56.9% in the presence of COPD alone (p < 0.01); mortality was 86.2% where CHF and COPD coexisted (p < 0.001) and was significantly higher than in CHF or COPD alone (p < 0.05). Multivariate analysis indicates that CHF (Hazard risk = 1.67, 95% confidence interval 1.15-3.27, p < 0.031) and COPD (Hazard risk = 1.27, 95% confidence interval = 1.08-1.85, p < 0.042) were predictive of long-term mortality. When CHF and COPD simultaneously occurred, the risk dramatically increased up to 3.73 (95% confidence interval = 1.19-6.93, p < 0.001). CONCLUSIONS: Long-term follow-up showed higher mortality among elderly subjects affected by CHF or COPD. Simultaneous presence of CHF and COPD significantly increased the risk of death. Therefore, the presence of COPD in CHF patients should be considered a relevant factor in predicting high risk of mortality.

The Italian version of the "frailty index" based on deficits in health: a validation study.

BACKGROUND AND AIM: Several measurements were taken for frailty classification in geriatric population. "Frailty index" is based on "deficits in health," but it is still not available in Italian version. Thus, the aim of the present work was to validate a version of "frailty index" for the Italian geriatric community. METHODS: The validation of Italian frailty index (IFi) is based on a cohort study that enrolled 1077 non-disabled outpatients aged 65 years or older (81.3 ± 6.5 years) in Naples (Italy). IFi has been expressed as a ratio of deficits present/deficits considered after a comprehensive geriatric assessment. IFi was stratified in light, moderate and severe frailty. Mortality, disability (considering an increase in ADL lost ≥1 from the baseline) and hospitalization were considered at 3, 6, 12, 18 and 24 months of follow-up. Area under curve (AUC) was evaluated for both Fried's and IFi frailty index. RESULT: At the end of follow-up, mortality increased from 1.0 to 30.3%, disability from 40.9 to 92.3% and hospitalization from 0.0 to 59.0% (p < 0.001 for trend). Multivariate analysis shows that the relative risk for unit increase in IFi is 1.09 (95% CI = 1.01-1.17, p = 0.013) for mortality, 1.04 (95% CI = 1.01-1.06, p = 0.024) for disability and 1.03 (95% CI = 1.01-1.07, p = 0.041) for hospitalization. AUC is higher in IFi with respect to Fried's frailty index when considering mortality (0.809 vs. 0.658, respectively), disability (0.800 vs. 0.729, respectively) and hospitalization (0.707 vs. 0.646, respectively). CONCLUSIONS: IFi is a valid measure of frailty after the comprehensive geriatric assessment in an Italian cohort of non-institutionalized patients.

Prognostic role of lactate on mortality in younger and older patients with cardio-respiratory failure admitted to an acute intensive care unit.

BACKGROUND AND AIM: Acidosis is able to induce negative changes of different organs that increase progressively with aging. At present it is not known whether the levels of lactate may differently influence the prognosis of younger and older patients. Thus, the aim of this study is to evaluate the prognostic value of lactate levels after admission of younger and older patients to an acute intensive care unit. METHODS: Younger (<65 years, n = 118) and older (≥65 years, n = 165) patients admitted to an acute intensive care unit were prospectively enrolled and classified according to diagnosis of acute heart or/and respiratory failure. For each patient, APACHE II score, time of hospitalization and mortality, blood levels of lactate were collected. RESULTS: Both in-hospital mortality and lactate >2.5 mmol/L at the admission was higher in the older than in the younger patients (42.4 vs. 20.3 %, p < 0.01 and 57.8 vs. 31.9 %, p < 0.01, respectively). Lactate level was higher in older than in the younger patients both at admission and after 24 h (3.9 ± 3.4 vs. 2.4 ± 2.2 mmol/L and 2.4 ± 2.0 vs. 1.4 ± 1.3 mmol, p < 0.01, respectively). Accordingly, multivariate analysis shows that lactate was predictive of mortality in younger (OR = 2.65, 95 % CI 1.62-5.24, p = 0.03) and even more in the older (OR = 4.74, 95 % CI 2.10-6.70, p < 0.01) patients. CONCLUSIONS: Lactate concentration increase is associated with increased mortality in younger patients but, even more so, in older patients admitted to an acute intensive care unit. These results confirm the experimental evidence showing acidosis has a greater effect of leading to organ failure and higher mortality with increasing age.

Midterm results of surgical treatment of displaced proximal humeral fractures in children.

PURPOSE: To analyse the clinical outcomes of 26 children treated surgically for displaced proximal humerus fracture. MATERIALS AND METHODS: From January 2008 to December 2012, 26 children/adolescents (14 boys, 12 girls) were treated surgically for displaced fractures at the proximal extremity of the humerus. Ten were grade III and 16 were grade IV according to the Neer-Horowitz classification with a mean age of 12.8 ± 4.2 years. Twenty young patients were surgically treated with a closed reduction and direct percutaneous pinning; six required an open approach. To obtain a proper analysis, we compared the Costant scores with the contralateral shoulder (Δ Costant). RESULTS: The mean follow-up period was 34 months (range 10-55). Two grade IV patients showed a loss in the reduction after percutaneous treatment. This required open surgery with a plate and screws. On average, the treated fractures healed at 40 days. The mean Δ Costant score was 8.43 (range 2-22). There was a statistically significant improvement in the mean Δ Costant score in grade III patients. In grade IV patients, there was a significant improvement in the mean Δ Costant score in those treated with open surgery versus mini-invasive surgery. CONCLUSIONS: Our study shows excellent results with percutaneous k-wires. This closed surgery had success in these patients, and the excellent outcomes noted here lead us to prefer the mini-invasive surgical approach in NH grade III fractures. In grade IV, the best results were noted in patients treated with open surgery. We suggest an open approach for these patients. LEVEL OF EVIDENCE: III.
