OBJECTIVE: The prone transpsoas approach is a single-position alternative to traditional lateral lumbar interbody fusion (LLIF). Earlier prone LLIF studies have focused on technique, feasibility, perioperative efficiencies, and immediate postoperative radiographic alignment. This study was undertaken to report longer-term clinical and radiographic outcomes, and to identify learnings from experiential evolution of the prone LLIF procedure.
METHODS: All consecutive patients undergoing prone LLIF for any indication at one institution were included (n = 120). Demographic, diagnostic, treatment, and outcomes data were captured via prospective institutional registry. Retrospective analysis identified 31 \'pre-proceduralization\' and 89 \'post-proceduralization\' prone LLIF approaches, enabling comparison across early and later cohorts.
RESULTS: 187 instrumented LLIF levels were performed. Operative time, retraction time, LLIF blood loss, and hospital stay averaged 150 min, 17 min, 50 ml, and 2.2 days, respectively. 79% of cases were without complication. Postoperative hip flexion weakness was identified in 14%, transient lower extremity weakness in 12%, and sensory deficits in 10%. At last follow-up, back pain, worst-leg pain, Oswestry, and EQ-5D health state improved by 55%, 46%, 48%, and 51%, respectively. 99% improved or maintained sagittal alignment with an average 6.5° segmental lordosis gain at LLIF levels. Only intra-psoas retraction time differed between pre- and post-proceduralization; proceduralization saved an average 3.4 min/level (p = 0.0371).
CONCLUSIONS: The largest single-center prone LLIF experience with the longest follow-up to-date shows that it results in few complications, quick recovery, improvements in pain and function, high patient satisfaction, and improved sagittal alignment at an average one year and up to four years postoperatively.

Pneumorrhachis is a medical condition that refers to the presence of air within the spinal canal. Many circumstances, including trauma, infection, or medical procedures, might lead to this syndrome.In some cases, pneumorrhachis may not cause any symptoms and can resolve on its own. However, it can also be associated with more severe underlying conditions, such as spinal fractures, spinal infections, or underlying lung pathologies that lead to air escaping into the spinal canal. In this case we report an incidental finding of pneumorrhachis in a patient who came to our attention for suspected sepsis.

Pressure ulcers are persistent skin lesions that have substantial detrimental effects on the physical well-being of patients. Moreover, their psychological ramifications for both patients and their caregivers are becoming more widely acknowledged. This research was conducted to examine the psychological ramifications of pressure ulcers and ascertain efficacious approaches to mitigate these effects and improve overall well-being. A cross-sectional study was conducted from March 2022 to December 2023 across tertiary care centres located in Beijing. The cohort consisted of 431 participants, which included primary caregivers and patients who were diagnosed with pressure ulcers. The data were gathered through the utilization of structured questionnaires and semi-structured interviews. These methods encompassed demographic details, clinical characteristics and validated scales that assessed psychological parameters, including quality of life, anxiety, stress and depression. The research exposed substantial psychological toll on both individuals receiving care and those providing care, with caregivers enduring diminished quality of life and elevated levels of anxiety, depression and stress (p < 0.05). A significant positive correlation was identified between the degree of psychological distress and severity of pressure ulcers (p < 0.05). Both location of the ulcer and duration of care were substantial contributors to the psychological burden (p < 0.05). In spite of the apparent necessity, a significant proportion of the participants refrained from obtaining psychological counselling. The results underscored the significant psychological ramifications of pressure ulcers for both individuals receiving care and the caregivers. As a result, comprehensive care strategies that incorporate psychological assistance into the prescribed treatment plan are imperative. This research highlighted the criticality of implementing all-encompassing, interdisciplinary approaches to tackle the complex issues presented by pressure ulcers in an effort to enhance the general welfare of those influences.

As today\'s society ages, age-related diseases become more frequent. One very common but yet preventable disease is the development of pressure ulcers (PUs). PUs can occur if tissue is exposed to a long-lasting pressure load, e.g., lying on tissue without turning. The cure of PUs requires intensive care, especially for the elderly or people with preexisting conditions whose tissue needs longer healing times. The consequences are heavy suffering for the patient and extreme costs for the health care system. To avoid these consequences, our objective is to develop a pressure ulcer prophylaxis device. For that, we built a new sensor system able to monitor the pressure load and tissue vital signs in immediate local proximity at patient\'s predilection sites. In the clinical study, we found several indicators showing correlations between tissue perfusion and the risk of PU development, including strongly reduced SpO2 levels in body tissue prior to a diagnosed PU. Finally, we propose a prophylaxis system that allows for the prediction of PU developments in early stages before they become visible. This work is the first step in generating an effective system to warn patients or caregivers about developing PUs and taking appropriate preventative measures. Widespread application could reduce patient suffering and lead to substantial cost savings.

BACKGROUND: A pressure sore (decubitus) is a wound that develops on the skin and subcutaneous tissue in places exposed to pressure. Primarily occurs in elderly, non-mobile individuals, the prevention and control of which requires not only medical and nursing participation, but it also financial expenditure.
OBJECTIVE: In our study, after a systematic document analysis, we present the relevant results of the decubitus survey conducted among state hospitals during Q2 of 2022, focusing on the organizational and management factors of decubitus prevention and care.
METHODS: The national survey was comprehensive in terms of the range of institutions relevant to decubitus care. After defining the selection criteria, we got a picture of 86 institutional practices for the base year of 2019.
RESULTS: During the review and systematization of domestic and European Union professional policy documents, regulators and strategy documents, it can be established that pressure ulcer prevention and care can be adapted to several development policy objectives, and its incidence appears as a quality indicator of the health sector.
CONCLUSIONS: Based on the results of our national decubitus survey, it can be said that domestic good practices operate in isolation, our reporting system is inhomogeneous, and the documentation is not uniform in our institutional system. 17 of the 86 institutions have new (2021-2022) documents regulating decubitus care at the institutional level, which in 17% of the institutions are dated 2010 or earlier. The scope of revision of the regulatory documents is set at 10% of the institutions. 61 of the examined institutions (71%) operate decubitus teams, 55 institutions (64%) use prophylactic bandages. There is a lack of professional monitoring measures and quality indicators, institutional-level expenditure analyses, controlling-type feedback, which would form the basis of costing and cost-effectiveness analyses.
CONCLUSIONS: In addition to our proposals for several organizational and managerial measures, we advocate the renewal of the relevant professional directive and the introduction of a uniform institutional reporting system as well. Orv Hetil. 2023; 164(21): 821-830.
Bevezetés: A felfekvés (decubitus) a nyomásnak kitett helyeken kialakuló seb a bőrön és a subcutisban. Elsősorban idős, nem mobilis egyénekben fordul elő, melynek megelőzése és kezelése nemcsak orvosi és ápolói részvételt, hanem anyagi ráfordítást is igényel. Célkitűzés: Tanulmányunkban a dokumentumelemzést követően az állami kórházak körében 2022. második negyedévében végzett decubitusfelmérés releváns eredményeit ismertetjük a decubitusprevenció és -ellátás szervezeti és menedzsmenti tényezőire fókuszálva. Módszer: Az országos felmérés a decubitusellátás szempontjából releváns intézményi kört tekintve teljes körű volt, a beválogatási kritériumok meghatározását követően 86 intézmény gyakorlatáról kaptunk képet a 2019. bázisévre vonatkozóan. Eredmények: A hazai és az európai uniós szakmapolitikai dokumentumok, szabályozók és stratégiai dokumentumok áttekintése és rendszerezése során megállapítható, hogy a felfekvés prevenciója és ellátása több fejlesztéspolitikai célkitűzéshez illeszthető, előfordulási gyakorisága az egészségügyi szektor minőségi indikátoraként jelenik meg. Megbeszélés: Az általunk megtervezett és elvégzett országos decubitusfelmérés eredményei alapján elmondható, hogy a hazai jógyakorlatok szigetszerűen működnek, jelentési rendszerünk inhomogén, a dokumentáció nem egységes az intézményrendszerünkben. A 86 intézményből 17 rendelkezik új keletű (2021–2022), intézményi szintű decubitusellátást szabályozó dokumentummal, melyek az intézmények 17%-ában 2010 vagy az előtti keltezésűek. A szabályozó dokumentumok felülvizsgálati hatálya az intézmények 10%-ában elő van írva. A vizsgált intézmények közül 61 intézmény (71%) működtet decubitusteamet, 55 intézmény (64%) használ profilaktikus kötszereket. Hiányoznak a szakmai monitoringmutatók, minőségi indikátorok, esetlegesek az intézményi szintű ráfordításelemzések, kontrolling jellegű visszamutatások, melyek a költség- és költséghatékonysági elemzések alapját képezhetnék. Következtetés: Több szervezeti és menedzsmenti intézkedést érintő javaslatunk mellett a vonatkozó szakmai irányelv megújítását és az egységes intézményi jelentési rendszer bevezetését is szorgalmazzuk.

UNASSIGNED: Ultrasound measurements of the aorta are typically taken in the axial plane, with the transducer perpendicular to the aorta, and diameter measurements are obtained by placing the callipers from the anterior to the posterior wall and the transverse right to the left side of the aorta. While the \'conventional\' anteroposterior walls in both sagittal and transverse plains may be suitable for aneurysms with less complicated geometry, there is controversy regarding the suitability of this approach for complicated, particularly tortuous aneurysms, as they may offer a more challenging situation. Previous work undertaken within our research group found that when training inexperienced users of ultrasound, they demonstrated more optimal calliper placement to the abdominal aorta when approached from a decubitus window to obtain a coronal image compared to the traditional ultrasound approach.
UNASSIGNED: To observe the level of agreement in real-world reporting between computed tomography (CT) and ultrasound measurements in three standard planes; transverse AP, sagittal AP and coronal (left to right) infra-renal abdominal aortic aneurysm (AAA) diameter.
UNASSIGNED: This is a retrospective review of the Otago Vascular Diagnostics database for AAA, where ultrasound and CT diameter data, available within 90 days of each other, were compared. In addition to patient demographics, the infrarenal aorta ultrasound diameter measurements in transverse AP and sagittal AP, along with a coronal decubitus image of the aorta was collected. No transverse measurement was performed from the left to the right of the aorta.
UNASSIGNED: Three hundred twenty-five participants (238 males, mean age 76.4 ± 7.5) were included. Mean ultrasound outer to the outer wall, transverse AP and sagittal AP diameters were 48.7 ± 10.5 mm and 48.9 ± 9.9 mm, respectively. The coronal diameter measurement of the aorta from left to right was 53.9 ± 12.8 mm in the left decubitus window. The mean ultrasound max was 54.3 ± 12.6 mm. The mean CT diameter measurement was 55.6 ± 12.7 mm. Correlation between the CT max and ultrasound max was r 2 = 0.90, and CT with the coronal measurement r 2 = 0.90, CT and AP transverse was r2=0.80, and CT with AP sagittal measurement was r 2 = 0.77.
UNASSIGNED: The decubitus ultrasound window of the abdominal aorta, with measurement of the coronal plane, is highly correlated and in agreement with CT scanning. This window may offer an alternative approach to measuring the infrarenal abdominal aortic aneurysm and should be considered when performing surveillance of all infra-renal AAA.

UNASSIGNED: Decubitus ulcers are common skin injuries in plastic and burn surgery departments, usually occur in patients with a long disease course and poor underlying health. Designing a reconstruction procedure with safety blood supply to a large volume soft tissue and resulting in minimal trauma is a priority for surgeons.
UNASSIGNED: The free-style perforators on the potential donor sites surrounding the ulcers were detected by Doppler, and the area of the ulcer was divided into several sections based on the location of pre-design perforator flaps. According to the insertion point of the perforators, small V-Y advancement flaps, propeller flaps and rotation flaps pedicled with freestyle perforators were formed and moderately modified during surgery. All of the small flaps were transplanted from donor sites to the defect and reassembled into a new composite flap to repair the ulcer. The donor sites were directly closed. The area of the flaps ranged from 7.0 × 10.5 cm to 8.0 × 22.0 cm and the diameter of the pedicle perforators ranged from 0.5 to 4.0 mm.
UNASSIGNED: In 30 patients, 65 flaps were constructed, and all of the flaps survived with direct closure of all donor sites. One case with effusion healed 1 month postoperatively through draining and application of a mild pressure dressing. After a 3-24 months follow-up period, all of the patients were satisfied with post-operative function and appearance, and only one case had a local recurrence 6 months postoperatively.
UNASSIGNED: The jigsaw puzzle flap based on freestyle perforators can repair the large skin and soft tissue defects caused by decubitus ulcers on the buttocks, with direct donor flap area closure. This method is easy to perform with a safe blood supply and minimal trauma resulting from the avoidance of microvascular anastomosis and the conventional myocutaneous flap.

Pressure ulcers (PUs) are one of the leading potentially preventable adverse events in the hospital. Critically ill patients are at risk for the development of PUs. The primary aim of the study was to investigate the relation of PUs and obesity in critically ill ICU patients.
A single center prospective cohort study was conducted on adult patients with obesity (defined as a body mass index BMI ≥ 30 kg/m2) and patients without obesity (BMI 18-25 kg/m2) admitted to the intensive care unit between May 2013 and July 2017 with an ICU length of stay of at least 3 days without pre-existing PUs at admission.
851 of 1205 patients (70.6%) had a normal BMI and 354 (29.4%) had a BMI ≥ 30 kg/m2 and were considered obese. Overall, 157 patients (13.0%) developed PUs; 112/851 (13.2%) of patients without obesity and 45/354 (12.7%) of patients with obesity (p = 0.907). There was no difference in the severity (p = 0.609) and PU location (p = 0.261). Mean days to PU development was 11.1; 11.7 days for patients without obesity and 9.5 days for patients with obesity (p = 0.270). Mean days to PU recovery was 13.2, which was 14.1 days for patients without obesity and 10.8 days for patients with obesity (p = 0.215). A multivariate logistic regression model showed no significant correlation between the occurrence of PUs in the ICU and obesity (OR 0.875 with 95% CI 0.528-1.448, p = 0.594). Subgroup analysis showed that patients with morbid obesity (BMI ≥ 40 kg/m2) developed PUs earlier during ICU admission when compared to patients without obesity (p = 0.004).
Our study demonstrates that obesity is not an independent risk factor for the development of PUs in the ICU. However, patients with morbid obesity might develop PUs earlier compared to patients without obesity.

BACKGROUND: Lateral interbody fusion (LIF) is traditionally performed with the patient in lateral decubitus, requiring repositioning to prone for adjunctive posterior procedures, or modifying traditional posterior techniques to be done while positioned lateral. The benefits of lateral anterior column access may be achievable with the patient prone, allowing for concomitant posterior techniques in a more familiar single-position setting.
METHODS: Prone transpsoas (PTP) access was outlined and vetted by a group of LIF-experienced spine surgeons. Early clinical experience included prospectively capturing procedural details and perioperative outcomes across a multi-centre cohort of clinicians to assess feasibility and to identify efficiencies and/or challenges.
RESULTS: Perioperative data was prospectively collected from 120 consecutive cases (176 levels) from 22 surgeons. Lateral exposure was achieved in an average 18 min/level, guided by triggered EMG; and retraction time averaged 25 min/level, with continued plexus monitoring via saphenous SSEP. Fixation was via percutaneous pedicle screws (65%), open pedicle screws (24%), other (11%). No re-positioning was required. Concomitant procedures facilitated by prone position included direct decompression (37%), treatment at L5-S1 (18%), posterior instrumentation revision (7%), and osteotomy/bony releases (9%). PTP procedure time, blood loss, and length of stay were consistent with established LIF experience. Challenges included patient movement with lateral instrument forces, retractor sag, stability of access relative to the patient, and surgeon ergonomics of the working channel. These challenges were overcome later in the experience through development of a specialized positioner and retractor system specific to this approach and a prescribed workflow developed by consensus of the surgeons.
CONCLUSIONS: Initial multi-centre clinical experience suggests that PTP is not only feasible but creates efficiencies by allowing for single-position surgery maximizing both anterior and posterior column access and corrective techniques, with perioperative outcomes consistent with lateral decubitus experience. Learnings included the need for development of procedure-specific technologies and technique refinement.

To determine the superiority of decubitus and supine radiographs for the reduction of olisthesis instead of the extension radiograph, and the inconsistency of the CT scout view, 3D-reconstruction and MR image in evaluating segmental instability.
A cohort of 154 low-grade lumbar degenerative spondylolisthesis patients with the average age of (60.9 ± 8.6) years were enrolled. Slip percentage was measured on the flexion, upright and extension radiographs, the decubitus lateral radiograph, CT scout view, the supine median sagittal 3D-reconstruction and MR image. The translational range of motion was calculated, and segmental instability was defined as translational motion ≥ 8%.
The flexion radiograph showed higher slip percentage than upright radiograph (p < 0.001). The slip percentage of the MR image was lower than CT scout view (p = 0.003) and CT sagittal radiograph (p = 0.001) on the basis of statistical differences among three groups (p = 0.002). The slip percentage of the CT scout view, decubitus radiograph, and extension radiograph was statistically different (p = 0.01). The CT scout view and sagittal reconstruction had lower slip percentage than the extension radiograph (p = 0.042; p = 0.003, respectively). Both the flexion-supine and flexion-decubitus modality had larger translational motion than the flexion-extension modality (p = 0.007; p < 0.001, respectively).
Many modalities and techniques are used to show the vertebral displacement and its possible change and any cane used in the daily practice. In this study, supine and decubitus lateral radiography have larger reduction of olisthesis than the extension radiograph. The flexion radiograph coupled with a supine or decubitus radiograph reveals greater mobility than the flexion-extension modality.
