Temporary immobilization methods for closed low-energy ankle fracture-dislocations: comparative analysis of a retrospective cohort.

PURPOSE: Ankle fracture-dislocations (AFD) often necessitate staged management involving temporary external fixation (EF) due to mechanical instability or blistering. However, limited literature exists on the optimal temporary immobilization method for low-energy closed AFD. This study compared baseline patient and fracture characteristics, along with clinical and radiological outcomes between AFD initially immobilized with EF versus splinting. METHODS: A retrospective cohort study was conducted involving patients with AFD temporarily immobilized using EF or splinting, followed by definitive open reduction and internal fixation. Quality of reduction (QOR) was assessed for each patient post-initial immobilization and after the definitive surgery. RESULTS: The study encompassed 194 patients: 138 treated with a splint (71.1%) and 56 (28.9%) with EF. Secondary loss of reduction had occurred in three patients who were splinted (2.2%). The mean ages in the EF and splint groups were 63.2 and 56.1 years, respectively (p = 0.01). Posterior malleolus fracture (PMF) and blisters were more prevalent in EF patients (69.6% vs. 43.5% for PMF and 76.8% vs. 20.3% for blisters, respectively; p = 0.05 and p < 0.01). Postoperative complication rates were 8.9% for EF versus 10.9% for splinting (p = 0.69). Satisfactory final QOR was attained in 79.8% of patients treated with a splint versus 64.3% with EF (p = 0.02). CONCLUSION: Patients immobilized by EF presented with poorer baseline characteristics and had more unstable injuries. Nevertheless, postoperative complication rates were comparable. Thus, EF appears to be a valuable tool for standardizing outcomes in AFD patients with a less favorable prognosis.

Vancouver B2 periprosthetic hip fractures treatment: fix or replace? A retrospective study comparing both techniques.

INTRODUCTION: Vancouver B2 periprosthetic hip fractures involve stem stability and they have been classically treated with revision surgery. Crucial factors such as age, clinical comorbidities and functional status are often neglected. The current study aims to compare clinical outcomes between patients treated with open reduction and internal fixation (ORIF) or femoral stem exchange. METHODS: This is a retrospective study that includes all Vancouver B2 periprosthetic hip fractures in a tertiary referral hospital from 2016 to 2020. Patients were divided into two groups: Group 1. Patients treated with an ORIF and Group 2. Patients treated with stem replacement. The outcomes that were compared between groups included demographic data, functional capacity, complications and mortality. RESULTS: 29 periprosthetic Vancouver B2 fractures were finally analyzed. 11 (37.9%) were treated with ORIF (Group 1) and 18 (62.1%) by stem replacement (Group 2). Surgery time (143 vs. 160 min), hemoglobin drop (1.8 vs. 2.5 g/dL) and hospital stance (25.5 vs. 29.6 days) were shorter in Group 1. According to complications, 18.2% of patients in the ORIF group had orthopedic complications compared with 44.4% in the revision group. In the revision group, 3 cases needed a two-stage revision and one of these revisions ended up with a resection arthroplasty (Girdlestone). The first-year mortality rate was 27% in Group 1 and 11% in Group 2. DISCUSSION: ORIF treatment seems to be a less aggressive and complex procedure which can lead to a faster general recovery. Revision surgery can imply a higher risk of orthopedic complications which can be severe and may require further aggressive solutions. The ORIF group mortality was similar to the proximal femur fracture rate (20-30%). In conclusion, ORIF treatment seems to be a good option especially in fragile patients with low functional demand when anatomical reduction is possible.

Fractures after cephalomedullary nailing of the femur : Systematization of surgical fixation based on the analysis of a single-center retrospective cohort.

PURPOSES: Femoral implant related fractures (IRF) are a growing pathology in an increasingly elderly and frail population. A series of IRF after cephalomedullary nail (CMN) fixation of a femoral fracture is analyzed and an algorithm described to guide the management of such fractures. METHODS: All eligible patients operated on for IRF fixation after CMN were reviewed regarding their demographics, comorbidities, injury pattern, and treatment. Primary outcomes were mortality and local complications. Secondary outcomes were time to consolidation, time to weight-bearing initiation, length of hospitalization, and discharge destination. RESULTS: The incidence of IRF requiring fixation was 1.3% after 3401 CMN implantation procedures. Elderly women with comorbidities and plate fixation predominated. One-year mortality was 18.6%, being higher for patients presenting with infection and those unable to walk at the end of follow-up. Local complications occurred in 25.6%. Median time to weight-bearing was 9.1 weeks, but longer for patients with plate fixation or complications. Patients presenting with an infection and those discharged to nursing facilities had more comorbidity. CONCLUSIONS: Following an algorithm presented here, patients were treated either with nail exchange or lateral locking plate fixation, permitting straightforward evaluations and acceptable results in a very high-risk population.

Salvage hip replacement after cut-out failure of cephalomedullary nail fixation for proximal femur fractures: a case series describing the technique and results.

BACKGROUND: Cut-out failure following proximal femoral fracture fixation is a compromising complication warranting surgical treatment. We describe 24 patients with cut-out failure after cephalomedullary nail fixation managed with salvage hip replacement. METHODS: Twenty-four consecutive patients who had sustained a proximal femoral fracture from December 2009 to December 2019, were managed with cephalomedullary nail fixation and experienced a cut-out failure were reviewed retrospectively. Data on demographics, comorbidities, injury characteristics, treatment, and post-operative course were analysed. RESULTS: Among 2802 proximal femoral fractures assessed, 28 fixations failed due to cut-out, with 24/28 patients subsequently undergoing salvage hip replacement. Intertrochanteric fractures (66.7%) managed with short nails predominated (79.2%). The median tip-to-apex distance (TAD) was 19 mm, but only two fractures had a good quality of reduction. Inverse correlations were identified between patient age and the time from fixation to cut-out (r = - 0.57; p = 0.02), and between the time of nailing to failure among patients with a greater TAD (r = - 0.43; p = 0.04). Most patients were managed via cemented hemiarthroplasty (66.7%). Surgical time was longer for total hip replacements (175.4 vs. 136.8 min; p < 0.01), but no bleeding or blood transfusion requirement differences were found. Two patients had orthopaedic complications, and three patients died within the first follow-up year. CONCLUSION: In our series, 1% of the proximal femoral fractures managed with a cephalomedullary nail failed due to cut-out. Salvage hip replacement appeared to be a relatively safe and reliable procedure for managing this challenging complication in patients who typically are elderly and physically frail.

Challenges and outcomes in the treatment of floating knees. A case series of ipsilateral femur and tibia fractures around the knee.

BACKGROUND: Ipsilateral femur and tibia fractures around the knee (floating knee) are rare injuries that threaten both limb viability and patient life. A correct surgical strategy is essential to reduce complications and sequelae. The aim of this study was to evaluate characteristics and results of treatment in patients with a floating knee treated at a single trauma center. MATERIAL AND METHODS: This is a retrospective and non-consecutive case series of 18 floating knees occurred in 17 patients. All patients were operated in a single third-level public and university hospital from December 2010 to December 2018. Data on demographics, injuries, treatment and follow-up were collected. A general health questionnaire (SF-12) and a knee functional questionnaire (KOOS-PS) were used to display results. RESULTS: We identified 13 men and 4 women, aged between 16 and 52. Mean follow-up period was 16.49 months. High-energy trauma following a traffic collision was the most frequent mechanism. Mean Injury Severity Score (ISS) was 39.05, and a damage control strategy was used in 15 (83.33%) injuries. Extra-articular fractures (Fraser I) largely predominated, resulting in double intramedullary nailing in 72.22% of cases. Eleven injuries (61.11%) presented with an open fracture. Complications appeared in 6 (33.33%) injuries, being 3 infections. Mean score for the SF-12 was 35.59 for the physical dimension and 50.44 for mental dimension. Mean score for the KOOS-PS was 43.64. CONCLUSION: Floating knee injuries usually occur in polytrauma contexts. Visceral involvement and exposed fractures are common, so the most appropriate strategy is usually a staged treatment. Complications and sequelae are frequent.

Prone position fibula nail and tibia buttress plate for large Volkmann fracture-dislocations technical note and preliminary results on a short case series.

Large posterolateral tibial fragments, known as Volkmann fractures, are common in ankle fracture-dislocations and typically require open reduction and fixation with interfragmentary screws and often buttress plates using a prone posterolateral approach. In this setting, fibula plating often necessitates dissection of the lateral window between the peroneal tendons and the skin, increasing wound-related complications. In recent years, intramedullary nailing of fibula fractures has gained popularity as a minimally invasive technique that allows load-sharing stabilization. However, this procedure has traditionally been performed in the supine position, which can pose challenges if a Volkmann-type fracture is present, requiring repositioning and losing access to the fibula through the posterolateral approach. Our objective is to describe a technique for fixing ankle fracture-dislocations with large posterolateral fragments using tibial buttress plates and fibula nails through a prone posterolateral approach without dissecting the lateral window. Additionally, we will present a case series with preliminary results.

Staged treatment of bicondylar tibial plateau fractures: influence of frame configuration and quality of reduction on outcomes.

PURPOSE: Despite evolving treatment, the surgical management of high-energy tibial plateau fractures (TPF) remains challenging, associating high rates of complications. In recent decades, staged management has emerged as an encouraging option. The main goal of our study was to evaluate the influence of bridging external fixation (EF) frame configuration and the resultant quality of reduction (QOR) on outcomes after staged-treatment of bicondylar TPF. METHODS: A retrospective review was conducted of patients with bicondylar TPF treated at our level-I trauma center using a staged-treatment protocol from January 2010 to January 2020. Data on baseline characteristics, injuries, treatments, and clinical/radiological results were collected. The QOR was evaluated on CT images after EF and on plain films after ORIF. RESULTS: Sixty-eight patients were eligible for analysis. By our criteria, QOR was good in 57.4% and 70.6% after EF and ORIF, respectively. A squared EF configuration was associated with superior EF QOR (p = 0.032), while better EF QOR was linked to improved ORIF QOR (p = 0.016). No relationship between ORIF delay and ORIF QOR was identified. Postoperative complications were documented in 19 patients. Average ROM at one-year follow-up was 114.9 ± 12.6°, and non-influenced by anterior femoral pin placement. CONCLUSIONS: Staged management of bicondylar TPF resulted in a reasonable rate of complications. A direct relationship between QORs obtained with EF and after ORIF was found. Squared frames were associated with faster and better reductions, regardless of the surgeon's background. Considering our results, we advocate for the wider use of squared EF configurations in these patients.

Outcomes and their predictors in suprapatellar nailing for tibia fractures. Multivariable analysis of 293 consecutive cases.

PURPOSE: Intramedullary nailing of tibial fractures is one of the most common procedures in orthopedic surgery. It can be technically demanding in proximal or distal fractures, which may be facilitated using semi-extended approaches. The aim of this study is to identify outcomes and their predictors using a semi-extended suprapatellar approach for tibial fracture nailing. METHODS: This is a retrospective cohort of 293 patients who underwent intramedullary nail fixation of a tibial fracture through a suprapatellar approach, considering a postoperative follow-up of 1 year. Data on patient's baseline characteristics, injuries, treatments, and outcomes regarding alignment, fracture union, and complications were recorded. For multivariable analysis, hierarchical binary (logistic) regression analysis was performed. RESULTS: The mean patient age was 47.7 years (SD 18.9), with 42A1 the most frequent fracture pattern (n = 98, 33.5%). Correct or anatomical alignment (≤ 5º in both planes) was achieved in 272 (92.8%) of the patients. On multivariate analysis, surgical delay ≥ 7 days (OR = 1.3, 95% CI = 1.3-8.1) and age over 50 years (OR = 3.2, 95% CI = 1.2-8.3) were found as predictors of fracture malalignment. Fracture healing was achieved in 97.6%, and reoperation rate was 6.14%. Overall complication's predictors were proximal fracture (OR = 2.8, 95% CI = 1.1-7.2), temporary external fixation (OR = 2.4, 95% CI = 1.2-4.9), and fracture malalignment (OR = 2.9, 95% CI = 1.1-7.9). CONCLUSION: The suprapatellar approach is a safe and useful technique for treating tibial fractures, leading to no less than correct reduction in almost all patients and achieving a high fracture healing rate, at very low rates of complications. Pre- and postoperative predictors identified must be taken into account to improve outcomes while treating these fractures.

Mortality, perioperative complications and surgical timelines in hip fracture patients: Comparison of the Spanish with the non-Spanish Cohort of the HIP ATTACK-1 trial.

BACKGROUND: Hip fractures carry a substantial risk of complications and death. This study aimed to report the 90-day incidence of mortality, major perioperative complications and in-hospital timelines after a hip fracture in the Spanish HIP ATTACK-1 trial cohort, comparing with the non-Spanish cohort. METHODS: Prospective cohort study of Spanish patients nested in the HIP ATTACK-1 trial. The HIP ATTACK-1 was an international, randomized, controlled trial (17 countries, 69 hospitals, 7 in Spain, highest recruiting country). Patients were randomized to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. Participants were ≥45 years of age who presented with a low-energy hip fracture requiring surgery. RESULTS: Among 534 patients in the Spanish cohort, 69 (12.9 %) patients died at 90 days follow-up, compared to 225 (9.2 %) in the non-Spanish cohort (p = 0.009), mostly due to higher nonvascular related mortality. A composite of major postoperative complication occurred in 126 patients (23.6 %). The most common perioperative complications were myocardial injury (189 patients, 35.4 %), infection with no sepsis (86 patients, 16.1 %) and perioperative delirium (84 patients, 15.7 %); all these complication rates in Spain were significantly higher than the non-Spanish patients (29.2 % p = 0.005; 11.9 % p = 0.008 and 9.2 % p < 0.0001, respectively). Spanish cohort patients were older and had more comorbidities than the non-Spanish cohort, evidencing their greater frailty at baseline. Among Spanish patients, the median time from hip fracture diagnosis to surgery was 30.0 h (IQR 21.1-53.9) in the standard-care group, with 68.8 % of patients receiving surgery within 48 h of diagnosis. This median time was lower in the non-Spanish cohort (22.8 h, IQR 9.5-37.0), where 82.1 % of patients were operated within 48 h. CONCLUSIONS: In the HIP ATTACK-1 trial, 1 in 8 patients died 90 days after a hip fracture in Spain. The most common complication after a hip fracture was myocardial injury, followed by infection and delirium. Spanish patients had worse outcomes than non-Spanish patients. Research needs to focus on new interventions such as accelerated surgery and perioperative troponin measurement with the appropriate investment of resources, to prevent and identify early these complications with a goal of improving mortality for this high-risk population. LEVEL OF EVIDENCE: II.

Predictors of outcomes after internal fixation of periprosthetic femoral hip fractures Subgroup analysis of the peri-implant and peri-prosthetic fractures Spanish registry (PIPPAS).

PURPOSE: To identify risk factors predisposing patients to poor outcomes after fixation of periprosthetic hip fractures around femoral stems. METHODS: Prospective multicentre cohort study of fractures around a hip replacement stem managed by internal fixation. The primary outcome was one-year mortality, while secondary outcomes were local complications and healthcare burden-related outcomes (nursing facility utilization and hospital length of stay). RESULTS: One-year mortality was 16.2%. Age-adjusted Charlson Comorbidity Index score (OR=1.17; 95%CI=1.03-1.33)), Pfeiffer Short Portable Mental Status Questionnaire (SPMSQ) score (OR=1.16; 1.06-1.28), prosthetic dysfunction (OR=1.90; 1.00-3.61), and postoperative medical complications (OR=1.97; 1.06-3.68) were predictors of mortality. Patients with prior prosthetic dysfunction, lower Pfeiffer SPMSQ scores, Vancouver A fractures, and fractures fixed only using cerclages were at higher risk of local complications, which occurred in 9.3% of cases. Medical (OR=1.81; 1.05-3.13) and local complications (OR=5.56; 2.42-3.13) emerged as consistent risk factors for new institutionalization. Average hospitalization time was 13.9±9.2 days. Each day of fixation delay led to an average 1.4-day increase in total hospitalization. CONCLUSION: Frail periprosthetic hip-fracture patients with poorer functional status, dysfunctional replacements, and postoperative complications are at increased risk of mortality. Postoperative complications are more common in patients with dysfunctional arthroplasties, Vancouver A fractures, and fixation using cerclages alone. Postoperative complications were the most consistent predictor of higher healthcare resource utilization.

Non-prosthetic implant-related femur fractures in post-polio patients.

The overall societal impact of poliomyelitis worldwide is decreasing, rendering it almost absent in most developed countries. However, even there, patients are still seen who contracted it in endemic areas or developed polio before vaccinations became widely available. Post-polio syndrome (PPS) causes skeletal and neurological changes that increase affected individuals' likelihood of fractures, including fractures requiring complex surgical treatment. The existence of previous internal fixation creates a particularly difficult challenge. We present here the surgical management of four post-polio patients who suffered non-prosthetic implant-related femoral fractures. Injuries occurred at earlier ages than implant-related fractures in non-polio patients and three of the four fractures occurred around plates, a phenomenon which is usually rare. The treatment of implant-related fractures in patients with post-polio syndrome poses significant technical challenges, often creating problematic functional sequelae for patients and high costs for healthcare systems.

Open reduction and polyaxial plating for stemmed knee periprosthetic fractures: A case series.

INTRODUCTION: Stemmed total knee arthroplasty (STKA) periprosthetic fractures (PPFs) are an emerging problem affecting frail patients. Their surgical fixation is challenging, due to intramedullary involvement and poor bone stock. Polyaxial locking plating has yielded good results in implant-related femur fractures. We hypothesized that this treatment would provide similar results for STKA PPFs. METHODS: Retrospective analysis of consecutive patients with a femoral PPF or inter-implant fracture around a knee revision stem who had undergone open reduction and periprosthetic-specific polyaxial plate fixation. RESULTS: We found 14 cases of mean age 85.4 years. Cerclages were used in 80% of cases. Fixation of a mean 8.6 cortices around the revision stem was achieved, with an overall screw density of 1:2 or 1:3. Four patients lost their ability to walk, while four experienced postoperative local complications. Bone healing was achieved in all except one who died during hospitalization. The 13 remaining survived the first year of follow-up. CONCLUSION: STKA PPFs are an emerging and challenging problem affecting frail patients. Treatment using polyaxial locking plates provides stable fixation allowing early mobilization despite high complication rates.

Treatment of a post-traumatic stiff knee after an open extensor apparatus injury by arthroscopic arthrolysis through a free flap.

Open patella fractures have high complication rates. Post-traumatic joint stiffness is particularly common. The management of this complication is even more difficult if free flap was used to cover a soft tissue defect. Late surgical manipulation of free flaps can lead to their failure, with catastrophic consequences. The use of minimally invasive techniques could reduce the associated risks. We present a case of knee stiffness after the fix and flap treatment of a grade IIIB open patella fracture. We performed an arthroscopic arthrolysis with portals through the flap. The pedicle was preoperatively located and avoided. Joint range of motion remarkably improved without records of flap complications. We consider that the technique is feasible. Its success was based on the multidisciplinary collaboration between orthopaedic and plastic surgeons and rehabilitation medicine specialists.

Usefulness of PCR Screening in the Initial Triage of Trauma Patients During COVID-19 Pandemic.

BACKGROUND: Hospitals worldwide have postponed all nonessential surgery during the COVID-19 pandemic, but non-COVID-19 patients are still in urgent need of care. Uncertainty about a patient's COVID-19 status risks infecting health care workers and non-COVID-19 inpatients. We evaluated the use of quantitative reverse transcription polymerase chain reaction (RT-qPCR) screening for COVID-19 on admission for all patients with fractures. METHODS: We conducted a retrospective cohort study of patients older than 18 years admitted with low-energy fractures who were tested by RT-qPCR for SARS-CoV-2 at any time during hospitalization. Two periods based on the applied testing protocol were defined. During the first period, patients were only tested because of epidemiological criteria or clinical suspicion based on fever, respiratory symptoms, or radiological findings. In the second period, all patients admitted for fracture treatment were screened by RT-qPCR. RESULTS: We identified 15 patients in the first period and 42 in the second. In total, 9 (15.8%) patients without clinical or radiological findings tested positive at any moment. Five (33.3%) patients tested positive postoperatively in the first period and 3 (7.1%) in the second period (P = 0.02). For clinically unsuspected patients, postoperative positive detection went from 3 of 15 (20%) during the first period to 2 of 42 (4.8%) in the second (P = 0.11). Clinical symptoms demonstrated high specificity (92.1%) but poor sensitivity (52.6%) for infection detection. CONCLUSIONS: Symptom-based screening for COVID-19 has shown to be specific but not sensitive. Negative clinical symptoms do not rule out infection. Protocols and separated areas are necessary to treat infected patients. RT-qPCR testing on admission helps minimize the risk of nosocomial and occupational infection. LEVEL OF EVIDENCE: Diagnostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Effectiveness of a multidisciplinary educational intervention in patients with hip fracture: SWEET HOME study. / Efectividad de una intervención educativa multidisciplinar en pacientes con fractura de fémur: estudio SWEET HOME.

BACKGROUND AND OBJECTIVE: Hip fracture is a common injury among elderly patients. The main goal of our study was to assess the effectiveness of a multidisciplinary educational intervention aimed at hip fracture patients to promote home discharges and reduce in-hospital complications. MATERIAL AND METHOD: A quasi-experimental study was performed by taking repeated measurements at hospital admission, at hospital discharge, and at both 30days and one year of discharge. Patients aged ≥65years with hip fracture who were admitted to the Orthogeriatric Service between February 2016 and January 2017 were included in the study. The educational intervention consisted in two coordinated actions: patient education administered during their hospitalization and multimodal support provided during their discharge home. RESULTS: A total of 67 patients were included in the study (77.6% of whom were women; 84.19±7,78 years old). Of these, 70.1% were discharged home, which doubles the figures recorded in the 2014-2015 period. The rate of readmission at 30days and one year of the discharge was 8.5%. At the one-year follow-up, the patient's dependence to perform basic activities of daily living was nearer to the pre-fracture level (Barthel: 86.67±19.31; 94.33±14.66), their mobility had improved in comparison with the time of discharge (Parker: 4.73±1.84; 6.73±2.76; Timed Up and Go Test: 38.29±21.27; 21.91±10.97), and their cognitive function had not worsened significantly. The patient education measures improved the patients' autonomy as perceived by the patients, the caregivers, and the healthcare providers. Satisfaction with the healthcare received was high. CONCLUSIONS: As a novelty to the already described benefits in orthogeriatric care models, this study would contribute by proving an increase of the number of patients discharged home in a safe condition.

Rationale and design of the HIP fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) Trial: a protocol for an international randomised controlled trial evaluating early surgery for hip fracture patients.

INTRODUCTION: Annually, millions of adults suffer hip fractures. The mortality rate post a hip fracture is 7%-10% at 30 days and 10%-20% at 90 days. Observational data suggest that early surgery can improve these outcomes in hip fracture patients. We designed a clinical trial-HIP fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) to determine the effect of accelerated surgery compared with standard care on the 90-day risk of all-cause mortality and major perioperative complications. METHODS AND ANALYSIS: HIP ATTACK is a multicentre, international, parallel group randomised controlled trial (RCT) that will include patients ≥45 years of age and diagnosed with a hip fracture from a low-energy mechanism requiring surgery. Patients are randomised to accelerated medical assessment and surgical repair (goal within 6 h) or standard care. The co-primary outcomes are (1) all-cause mortality and (2) a composite of major perioperative complications (ie, mortality and non-fatal myocardial infarction, pulmonary embolism, pneumonia, sepsis, stroke, and life-threatening and major bleeding) at 90 days after randomisation. All patients will be followed up for a period of 1 year. We will enrol 3000 patients. ETHICS AND DISSEMINATION: All centres had ethics approval before randomising patients. Written informed consent is required for all patients before randomisation. HIP ATTACK is the first large international trial designed to examine whether accelerated surgery can improve outcomes in patients with a hip fracture. The dissemination plan includes publishing the results in a policy-influencing journal, conference presentations, engagement of influential medical organisations, and providing public awareness through multimedia resources. TRIAL REGISTRATION NUMBER: NCT02027896; Pre-results.

Salvage for intramedullary nailing breakage after operative treatment of trochanteric fractures.

BACKGROUND: Trochanteric fractures are one of the most common fractures in elderly people. The use of intramedullary nails is an option for their treatment, especially in unstable patterns. Nail breakage is a rarely reported complication. The aim of this study was to determine the prevalence of nail breakage in our center. Secondary objectives are to show the management of this complication in our institution as well as the technical problems, complications and final outcomes of these patients in our hands. MATERIAL AND METHODS: In a retrospective case series review between 2010 and 2015, we analyzed 1481 patients with trochanteric and subtrochanteric fractures who had been treated by cephalomedullary nailing in our centre. 13 patients with nail breakage were identified. RESULTS: The percentage failure rate in our institution is 0.87%. 9 (69.2%) patients were women and 4 (3.8%) were men, with a mean age of 74.6 years (range 47-90). In all cases the mechanism of injury was a simple fall from standing height. Initial fracture types were: 1 case of AO/OTA 31A1, 6 cases of AO/OTA 31A2 and 6 cases of AO/OTA 31A3. Only 3 cases had a good overall reduction with a correct TAD, an optimal femoral neck-shaft angle and absence of fracture gaps >5 mm after surgery. The average time from the first surgery to the diagnosis of implant breakage was 333 days (range 70-1460), 11 months. Breakage occurred at the nail junction with the lag screw in 11 cases and in the distal nail aperture in 2 cases. CONCLUSIONS: An insufficient reduction with varus and fracture gaps >5 mm, the use of short nails in unstable patterns with subtrochanteric involvement and patients with certain comorbidities are facts observed that can contribute to the development of delayed or nonunion with subsequent nail breakage. Different salvage treatments, conversion to hip arthroplasty or revision osteosynthesis, may be considered but we think that prevention has to be the best treatment.

Medium-term outcome of mosaicplasty for grade III-IV cartilage defects of the knee.

PURPOSE: To evaluate the medium-term outcome of mosaicplasty for full-thickness cartilage defects of the knee joint in 17 patients. METHODS: Records of 12 men and 5 women aged 16 to 57 (mean, 35) years who underwent mosaicplasty for grade III/IV osteochondral defects in the lateral (n=14) or medial (n=3) femoral condyle were reviewed. 12 of the patients had undergone knee surgeries. The mean size of the defects was 3.4 (range, 1-4) cm(2). Three patients had defects of >2 cm(2). All operations were performed by a single surgeon using mini-arthrotomy. The lateral edge of the trochlea was the donor site. Graft integration and the presence of any abnormality at the articular surface were assessed using magnetic resonance imaging (MRI). In addition, patients were evaluated using the International Knee Documentation Committee (IKDC) rating scale, the SF-36 health questionnaire, visual analogue scale (VAS) score for pain. RESULTS: Two of the 17 patients developed necrosis and cystic degeneration of the grafts and underwent conversion to unicompartmental knee arthroplasty within 2 years. They were older than 45 years and had defects of >2 cm(2). Respectively in years 4 and 7, one and 4 patients were lost to follow-up, the mean IKDC score was 75% and 88%, the SF-36 score was 83% and 90%, and the VAS score was ≤3 in 13 of 14 patients at year 4 and in all 11 patients at year 7. At the 7-year follow-up, patient satisfaction with mosaicplasty was excellent in 8 patients, good in 3, and poor in 2 (who underwent unicompartmental knee arthroplasty). At year 4, MRI showed integration of the cartilage repair tissue and incorporation of the osseous portion of the graft into the bone in 13 of the 14 patients. The remaining patient had osteoarthritis at the graft donor site. At year 7, MRI showed good integration of the implant in all 11 available patients, but fissures were seen on the cartilage surface in 3 patients. CONCLUSION: The medium-term outcome of autologous mosaicplasty for symptomatic osteochondral defects in the femoral condyle is good. Longer follow-up is needed to determine the structural and functional integrity of the graft over time.

Efectividad de una intervención educativa multidisciplinar en pacientes con fractura de fémur: estudio SWEET HOME / Effectiveness of a multidisciplinary educational intervention in patients with hip fracture: SWEET HOME study

Antecedentes y objetivo: La fractura de fémur (FF) es una lesión frecuente en personas de edad avanzada. El objetivo fue evaluar la efectividad de una intervención educativa multidisciplinar en pacientes con FF para favorecer el regreso al domicilio y disminuir las complicaciones hospitalarias. Material y método: Estudio cuasiexperimental con medidas repetidas al ingreso, al alta, a los 30días y al año de seguimiento. Se incluyeron pacientes ≥65años con FF ingresados en la unidad de ortogeriatría entre febrero de 2016 y enero de 2017. La intervención educativa constó de dos actuaciones coordinadas: una educación sanitaria durante la hospitalización y un soporte multimodal durante la transición al domicilio. Resultados: Se incluyeron 67 pacientes (77,6% mujeres; edad 84,19±7,78 años). Regresaron al domicilio el 70,1%, doblando la cifra de los años 2014-2015. Hubo un 8,5% de reingresos a los 30días y al año. Al año, el nivel de dependencia fue cercano al nivel prefractura (Barthel: 86,67±19,31; 94,33±14,66), la movilidad mejoró respecto al alta (Parker: 4,73±1,84; 6,73±2,76; Timed Up and Go test: 38,29±21,27; 21,91±10,97) y el rendimiento cognitivo no empeoró de forma significativa. La percepción de pacientes, cuidadores y profesionales fue que la educación sanitaria mejoró la autonomía del paciente. La satisfacción con el proceso asistencial fue alta. Conclusiones: Este estudio aporta como novedad, a los beneficios ya descritos en los modelos asistenciales ortogeriátricos, el incremento del número de pacientes que regresan al domicilio en condiciones de seguridad

Background and objective: Hip fracture is a common injury among elderly patients. The main goal of our study was to assess the effectiveness of a multidisciplinary educational intervention aimed at hip fracture patients to promote home discharges and reduce in-hospital complications. Material and method: A quasi-experimental study was performed by taking repeated measurements at hospital admission, at hospital discharge, and at both 30days and one year of discharge. Patients aged ≥65years with hip fracture who were admitted to the Orthogeriatric Service between February 2016 and January 2017 were included in the study. The educational intervention consisted in two coordinated actions: patient education administered during their hospitalization and multimodal support provided during their discharge home. Results: A total of 67 patients were included in the study (77.6% of whom were women; 84.19±7,78 years old). Of these, 70.1% were discharged home, which doubles the figures recorded in the 2014-2015 period. The rate of readmission at 30days and one year of the discharge was 8.5%. At the one-year follow-up, the patient's dependence to perform basic activities of daily living was nearer to the pre-fracture level (Barthel: 86.67±19.31; 94.33±14.66), their mobility had improved in comparison with the time of discharge (Parker: 4.73±1.84; 6.73±2.76; Timed Up and Go Test: 38.29±21.27; 21.91±10.97), and their cognitive function had not worsened significantly. The patient education measures improved the patients' autonomy as perceived by the patients, the caregivers, and the healthcare providers. Satisfaction with the healthcare received was high. Conclusions: As a novelty to the already described benefits in orthogeriatric care models, this study would contribute by proving an increase of the number of patients discharged home in a safe condition
