    Abstract Purpose: Biomechanical superiority of intramedullary nails over extramedullary implants has been proved for subtrochanteric fractures. Nevertheless, postoperative management of these patients has not changed, with high rates of protected weight-bearing after intramedullary nailing. The purpose of this study is to determine the mechanical complications of immediate postoperative full weigh-bearing for subtrochanteric femur fractures in elderly patients treated with a cephalomedullary nail.
    Methods: We performed a retrospective case series study from patients treated with a cephalomedullary nail for subtrochanteric fractures (AO/OTA 31A.3 and 32A-32C) over a nine-year period. Patients in the immediate full weight-bearing (IFWB) group received orders for immediate full weight bear as tolerated on postoperative 48 h. Patients in the non- or limited- weight-bearing (NLWB) group received orders not to full weight bear in the immediate postoperative.
    Results: There were five (2.7%) cases of implant failure including four cutouts and one nail breakage that needed a reoperation. Of them, one (2.2%) followed the NLWB protocol and four (2.9%) followed the IFWB protocol. Mean length of stay was 7.9 days (median 8, range 3-21) in the NLWB group and 10.7 days (median 8, range 2-60) in the IWBAT group. The NLWB group observed a 2.8-day shorter postoperative length of stay when compared to the IFWB, but the median remained equal.
    Conclusion: This study suggests that geriatric patients with subtrochanteric fractures treated by intramedullary nailing and in which a good fracture reduction was achieved, may be able to tolerate immediate postoperative full weight-bearing, not increasing reoperation rates due to implant failure.

    Abstract Introduction: The incidence of osteoporotic distal humeral fractures (DHF) is on the rise. Their operative management is demanding. Fixation with non-locking reconstruction plates was associate with a high number of complications. Elbow arthroplasty (total or hemi) has been proposed as an alternative treatment, in spite of lifetime activity restrictions, and risk of complications, unknown implant survival and problematic revision surgery. Precontoured anatomical locking plates have increased the strength of the fixation in complex fractures.
    Hypothesis: double plating ORIF with precontoured anatomical locking plates is a safe and reliable treatment option for the management of AO/OTA type C3 DHF in patients aged 75 and older.
    Patients and methods: A retrospective case series study of patients aged 75 years old and older with an AO/OTA type C3 DHF treated with ORIF with double precontoured anatomical locking plates between 2007 and 2021. Pathologic fractures were excluded. Patients' demographic, surgical, clinical, and radiological data were reviewed.
    Results: A total of 27 women and 3 men, mean age of 80.1 years (range 75-93 years), were included. Mean Charlson index was 5 (range 3-8). Out of 30 patients, 19 had already died. Mean survival time after the surgical treatment was 72.3 months. Mean Mayo elbow performance score was 88.9 (range 60-100); 23 patients scored excellent or good. All fractures healed with no cases of delay union or non-union, hardware failure or loss of reduction. No patient needed a revision surgery to arthroplasty. The total number of complications was 12 (40%), mainly ulnar neuropathy (5) and cerclage removal (4).
    Conclusion: ORIF with double pre-contoured locking plates may be a safe and reliable treatment for type C3 DHF in patients aged 75 years and older, with a good functional outcome. Complications are expected but not related to loss of reduction, fixation failure or revision to elbow arthroplasty.

    Abstract Recent studies confirm the applicability of Inertial Measurement Unit (IMU)-based systems for human motion analysis. Notwithstanding, high-end IMU-based commercial solutions are yet too expensive and complex to democratize their use among a wide range of potential users. Less featured entry-level commercial solutions are being introduced in the market, trying to fill this gap, but still present some limitations that need to be overcome. At the same time, there is a growing number of scientific papers using not commercial, but custom do-it-yourself IMU-based systems in medical and sports applications. Even though these solutions can help to popularize the use of this technology, they have more limited features and the description on how to design and build them from scratch is yet too scarce in the literature. The aim of this work is two-fold: (1) Proving the feasibility of building an affordable custom solution aimed at simultaneous multiple body parts orientation tracking; while providing a detailed bottom-up description of the required hardware, tools, and mathematical operations to estimate and represent 3D movement in real-time. (2) Showing how the introduction of a custom 2.4 GHz communication protocol including a channel hopping strategy can address some of the current communication limitations of entry-level commercial solutions. The proposed system can be used for wireless real-time human body parts orientation tracking with up to 10 custom sensors, at least at 50 Hz. In addition, it provides a more reliable motion data acquisition in Bluetooth and Wi-Fi crowded environments, where the use of entry-level commercial solutions might be unfeasible. This system can be used as a groundwork for developing affordable human motion analysis solutions that do not require an accurate kinematic analysis.

    Abstract Background: Clinical management in orthogeriatric units and outcome indicators are similar for extracapsular fragility hip fractures, without discriminating between subtrochanteric and pertrochanteric fractures.
    Hypothesis: Geriatric patients, 75 years or older, with subtrochanteric fractures have worse clinical and functional outcomes than those with pertrochanteric fractures.
    Materials and methods: Retrospective observational study of data prospectively collected by the Spanish Hip Fracture Registry including patients 75 years or older, admitted for extracapsular hip fractures from January 2017 to June 2019. Demographic and baseline status, pre-operative, post-operative and 30-day follow-up data were included.
    Results: A total of 13,939 patients with extracapsular hip fractures were registered: 12,199 (87.5%) pertrochanteric and 1740 (12.5%) subtrochanteric. At admission, patients with subtrochanteric fractures were younger (86.5 ± 5.8 versus 87.1 ± 5.6 years old), had better pre-fracture mobility (3.7 ± 2.7 versus 3.9 ± 2.8) (1-to-10 scale, 1 being independent) and were more likely to be living at home; those with pertrochanteric fractures had worse cognitive function (Pfeiffer 3.3 ± 3.3 versus 3.8 ± 3.5). The subtrochanteric fracture group showed worse post-fracture mobility (7.3 ± 2.7 versus 6.7 ± 2.7) and greater deterioration of mobility (3.7 ± 3.0 versus 2.9 ± 2.7). Among individuals living at home at baseline, those with subtrochanteric fractures were more likely to remain in an assisted facility at 30-day follow-up. In-hospital mortality during acute admission was higher for the subtrochanteric group (5.6% versus 4.5%) (p = 0.028). To our knowledge, this is the first paper highlighting the differences between these two fracture groups in the geriatric population.
    Conclusions: Subtrochanteric fractures in the older population are a different and worse entity, with greater morbimortality and functional decline than pertrochanteric fractures. Despite being younger and fitter at admission, older patients with subtrochanteric fractures have a higher risk of remaining non-weight bearing and undergoing re-operation and institutionalization. Orthogeriatric units should be aware of this and manage subtrochanteric fractures accordingly.

    Abstract Introduction: The aim of this study was to determine the feasibility of applying the MIPO technique with a helical-shaped plate in the treatment of humeral shaft fractures with proximal extension.
    Patients and methods: We present an observational prospective study of patients with a humeral shaft fracture involving the proximal humerus fixed with a long proximal humerus polyaxial locking plate with an anterior curvature and helical shape (ALPS® Zimmerbiomet, Warsaw, Indianapolis, USA), using a MIPO technique. Between January 2017 and July 2020, 15 patients were treated at our institution. Proximally a 4-5 cm anterolateral transdeltoid approach was made. And distally, a 5-7 cm incision was made 4 cm proximal to the elbow crease. At each follow-up, radiographs were taken to evaluate fracture healing. Funtional scales were applied to evaluate clinical results.
    Results: Ten women and five men were included, with a mean age of 62 yo (range 26-86). All but one fracture healed uneventfully. The mean time to union was 28 weeks (range 12-48 weeks). Two out of 15 patients presented complications (an atrophic nonunion and a peri‑implant distal fracture). None of the patients had a nerve palsy prior neither after the surgery. No other complications, including infection, were registered during follow-up. Shoulder range of motion showed the following means: abduction of 147° (range 50°-180°), anterior flexion of 144° (range 80°-180°), external rotation of 77,5 ° (range 70°-80°) and internal rotation of 54.5° (range 45°-60°). All patients recovered their pre-fracture elbow range of motion. All patients presented less than 10° of angular deviation in varus/valgus or ante/recurvatum after the surgical procedure. At the end of the follow-up, all final functional scores were "good" or "excellent": mean Constant-Murley score was 72 ± 13 (range 38-91), ASES score was 73 ± 12 (range 41-88), UCLA shoulder scale was 30 ± 3,5 (range 10-35), and Q-DASH score was 16.5 ± 0,11 (range 4-57).
    Conclusion: When applied correctly, the treatment of diaphyseal humeral fractures involving the proximal humerus using a polyaxial locking helical plate with a MIPO technique is a reliable treatment method. It has high union rates with low complications.

    Abstract Introduction: The objectives of this study were to describe the surgical technique of fixation of 3-4 part proximal humeral fractures with polyaxial locking plates utilising a minimally invasive approach and to evaluate the accuracy of reduction and stability of fixation.
    Patients and methods: We retrospectively reviewed 90 patients. Fractures were classified according to the Neer classification system. Different radiological parameters were measured to assess the quality of reduction and the stability of fixation. Complications and clinical outcomes were evaluated after one year of minimum follow up.
    Results: There were 76 women and 14 men, with a mean age of 67.4years ±13 (range, 29-85). There were 60 3-part and 30 4-part fractures. Frozen cancellous allograft was used in 30 cases (33.3%). All fractures progressed to union and at one year follow up, the mean Constant score was 79.6±12(range, 62-100). Mean forward flexion, abduction, external rotation and internal rotation were 155°, 148°, 39° and vertebra Dorsal 8, respectively. Complications were noted in seven patients while the postoperative "head-diaphysis angle", "greater tuberosity height" and "medial metaphysis reconstruction" were close to the anatomical parameters; no significant differences were noted at one year radiological follow up.
    Conclusion: Reliable and stable fixation can be expected with the use of polyaxial locking plate through a minimally invasive approach for the treatment of 3-4 part proximal humeral fractures. Satisfactory functional results for this procedure can be obtained.

    Abstract Large skeletal muscle injuries, such as a volumetric muscle loss (VML), often result in an incomplete regeneration due to the formation of a non-contractile fibrotic scar tissue. This is, in part, due to the outbreak of an inflammatory response, which is not resolved over time, meaning that type-1 macrophages (M1, pro-inflammatory) involved in the initial stages of the process are not replaced by pro-regenerative type-2 macrophages (M2). Therefore, biomaterials that promote the shift from M1 to M2 are needed to achieve optimal regeneration in VML injuries. In this work, we used elastin-like recombinamers (ELRs) as biomaterials for the formation of non- (physical) and covalently (chemical) crosslinked bioactive and biodegradable hydrogels to fill the VML created in the tibialis anterior (TA) muscles of rats. These hydrogels promoted a higher infiltration of M2 within the site of injury in comparison to the non-treated control after 2 weeks (

    Abstract Supervised, center-based, daily physiotherapy presents limitations: transport, need for an accompanying person, or risk of infection. Home-based rehabilitation protocols (HBRP) can be effective alternatives. We use a HBRP for the non-surgically treated proximal humeral fractures (PHF) in older patients.
    Objectives: To assess patient satisfaction and preferences of using a booklet, videos, or an app to guide physiotherapy.
    Patients and methods: Prospective, single-center observational study of patients ≥55 years old who sustained a non-surgically treated PHF. The HBRP consisted of immediate mobilization, followed by 5 physiotherapist-guided, weekly sessions of rehabilitation and standard physiotherapy after 3 months, if needed. A booklet with images, videos, or a smartphone application were offered to guide the patients.
    Results: Mean degree of satisfaction (1-5) was 4.66 ± .9: 84 patients (82.4%) were very satisfied, 11 patients (10.8%) were satisfied, and 5 patients (4.9%) were not satisfied at all. Mean Oxford Shoulder Score achieved was 40.5 ± 6.6. 59.8% patients preferred the booklet and 29.4% the videos. Exercise compliance was considered very high in 87.3% of patients, while 4% hardly never followed the HBRP. Only 17.7% patients needed center-based physiotherapy after the HBRP.
    Discussion: Reasons for satisfaction were good final functional outcome, no need for transportation, being away from hospital, immediate rehabilitation availability and being capable of maintaining independence. Adherence is a major concern. Videos are more didactic explaining the exercises.
    Conclusion: If standard physiotherapy is not available, the HBRP can be a valid treatment option for PHF management in older patients, with a high degree of patient satisfaction. Older patients preferred the booklet to guide physiotherapy.

    Abstract Background: Nonoperative management of proximal humeral fractures (PHFs) is the most common treatment, but its functional outcome may improve with early mobilization. In frail osteoporotic patients, quick recovery of prefracture independency is mandatory. This study assessed fracture displacement in PHFs managed with conservative treatment after early mobilization and a home-based self-exercise program.
    Methods: We retrospectively analyzed the radiologic displacement of fracture fragments of PHFs treated conservatively with early mobilization and a home-based self-exercise program.
    Results: Included were 99 patients with 26 one-part, 32 two-part, 32 three-part, and 9 four-part PHFs managed conservatively, followed by early mobilization and a home-based self-exercise program. In the x-ray examinations, the head displaced from varus into valgus 55° ± 23° to 42° ± 22°, in the normal range of anatomic values. The medial hinge displaced from medial to the diaphysis (+1 ± 6 mm) to lateral to the head (-0.6 ± 6 mm). The greater tuberosity displaced cranially from -1 ± 7 mm to 2 ± 5 mm. The Constant score at the 1-year follow-up was 79.69 ± 16.3.
    Discussion and conclusions: The home-based self-exercise program for conservative treatment of PHFs displaces the head-diaphysis angle and the medial hinge toward anatomic reduction, but there is a risk of greater tuberosity cranial displacement. Functional results are fairly good, allowing frail patients to keep on with their independency and life style. Because a large number of patients might need further physiotherapy, the quality of the home-based self-exercises should be supervised.
