Opis:
Introduction and aim. Preiser disease is an avascular necrosis of the scaphoid. It is a rare disease, and even less common among the pediatric population. Disease is idiopathic, occurring without trauma or scaphoid non-union. Diagnostic methods include classic radiology, CT, MRI and bone scan. Treatment may be both surgical and conservative, and main aim is pain relief and widening range of motion of the wrist. The main aim of this paper is to summarize available knowledge about Preiser disease in the pediatric population. Material and methods. The paper is based on scientific publications available in PubMed and NCBI databases. After evaluation of abstracts, papers were selected and analyzed, considering the references citied. Analysis of the literature. Preiser disease is rare in the pediatric population. Children tend to present better results after conservative treatment than adults. Currently there are no unified treatment recommendations in Preiser disease, as knowledge about this condition is still limited. Wider research is vital to unify management recommendations. Conclusion. Preiser disease can affect patients of both sexes at any age, but it is exceedingly rare in children. There is a need for controlled randomized studies to establish the treatment standards, which is challenging due to the rarity of the disease. By now, non-surgical treatment tends to be the most common among the pediatric population. Surgical methods implemented in this condition include vascularized bone grafts and proximal row carpectomy.

Opis:
Hydroxyapatite (HA), ß-tricalcium phosphate (ß-TCP) and their mixtures have been successfully applied in orthopedic, oral and maxillofacial surgery [1]. Calcium phosphate (CP) bioactive ceramics based on HA is usually fabricated of appropriate powders. Unfortunately, mechanical properties of such material are in general worse than those of human bone. Therefore, there is a necessity for development of new ceramic CP composites with improved characteristics. An effective biomaterial must simultaneously possess various, often contradictory, properties [2]. A functionally graded material (FGM) with gradients in composition, phase and microstructure from the surface to the interior can better satisfy such combined requirements. Recently, FGM's of sodium-containing calcium phosphates were prepared expecting them to have improved circumstances for bone formation and bonding [3-4]. The aim of this work was to study the thermal behavior of FGM's of sodium - containing calcium phosphates prepared by an original route. The initial powder was prepared by a simple one-step precipitation using Ca(NO3)2 and Na3PO4 reactants. The synthesis reaction resulted, besides HA, in the by product NaNO3. However, the latter was not washed out of the precipitate but rather used as a source of sodium for ceramics preparation. An original molding step was used resulted in gradient distribution of NaNO3 in compacts. They were sintered under usual conditions. It has been found that the linear (or volume) shrinkage and the density slightly changed in the fired compacts below 1100°C. However, the consolidation abruptly increased at 11000C. The poor sintering is associated with NaNO3 decomposition during heating and firing at temperatures below 11000C. At higher temperatures, reactions between HA particles and products of NaNO3 decomposition occurred and dif¬fusion processes were intensified. Due to the gradient distribution of NaNO3 in the compacts, the indicated thermal processes resulted in formation of functionally graded ceramics (having in particular a phase gradient from the surface to the interior as Na3Ca6(PO4)5\to ß- rhenanite\to Na+ solid solution in HA).

Opis:
Introduction: Alloplasty is one of the most frequently performed procedures, as it hugely improves the quality of life. Objectives: The purpose of this study was to determine the incidence, risk factors, and clinical implications of postdischarge pneumonia after hip endoprosthesis in Polish adults. Patients and methods: This retrospective study was conducted using the database of the National Health Fund (Narodowy Fundusz Zdrowia) containing data from 55 842 hip arthroplasties performed in 2017. Results: Postdischarge pneumonia was identified in 371 patients and accounted for 26.6% of all postdischarge infections, with incidence rate of 0.7%. Multivariable analysis showed a significantly higher risk of pneumonia in patients aged 65 and older (odds ratio [OR], 3.5; 95% CI, 2.40–5.03), urgently admitted (OR, 4.0; 95% CI, 3.16–4.98), operated in winter (OR, 1.7; 95% CI, 1.37–2.11), and hospitalized in the intensive care unit (OR, 5.9; 95% CI, 3.65–9.46). Preventative factors were pre-surgery treatment for diseases of the musculoskeletal system (OR, 0.7; 95% CI, 0.59–0.91) and postoperative rehabilitation (both outpatient and inpatient; OR, 0.3; 95% CI, 0.10–0.99 and OR, 0.7; 95% CI, 0.42–0.99, respectively). Seventy patients (18.9% of pneumonia cases) required inpatient pneumonia treatment. The in-hospital case fatality rate observed in postdischarge pneumonia was 21.4%. Conclusions: Pneumonia is one of the most common postoperative infections after hip endoprosthesis, especially in winter, requiring rehospitalization. Efforts should be made to prepare patients in the perioperative period.

Opis:
Giant cell tumor of tendon sheath is a rare and benign so-fttissue tumor, which is even less common in the pediatric population. It may be connected with chromosomal translocations, oeftn the 1p11-13. Symptoms include pain, swelling, palpable mass or limited range of motion. Magnetic resonance is the diagnostic method of choice. Histopathological image obtained from biopsy should be also evaluated. The gold standard of treatment is total surgical resection of the tumor, as incomplete excision may result in recurrence. Physicians should also consider the future function of the aefcted joint or limb. Our aim was to review the available literature about GCTTS in the pediatric population.

Opis:
The purpose of this study is the design of an ankle orthosis designed for people with excessive sweating. Considering the available solutions of these types of stabilizers, and taking into account the problem of hyperhidrosis, a device tailored to the anatomical structure of the patient was designed, keeping an appropriate level of ventilation and moisture absorption. A solution was proposed in the form of a personalized ankle orthosis, manufactured from biodegradable polylactide, using 3D printing. The design of the orthosis assumes an incomplete (hexagonal) arrangement of the structure. Therefore, experimental strength tests were carried out on PLA specimens produced by the FDM method with different degrees of density of the hexagonal structure. The tested samples were subjected to temporary exposure in an environment mimicking excessive sweating (0.9% NaCl solution). The developed test results made it possible to determine the effect of hyperhydrosis on the strength properties of the tested samples. They also made it possible to design an optimal ankle orthosis design.

Opis:
The aim of this paper was the application of a new dynamic-passive method of treatment in correction of hallux valgus and coexisting static deformities of the foot (transverse-plane and plano-valgus foot). Methods: The study involved 50 patients; 26 with full big toe correction after the passive correction grip (group I) and 24 with big toe correction requiring additional passive abduction (group II). The patients regularly performed exercises using the designed device according to the planned schedule. The progress of the correction was assessed by a medical examination and additional tests. Results: The cross-sectional area [cm2 ] of the abductor hallucis muscle in three-time points among I and II groups of patients with the hallux valgus was measured based on MRI images. The STIR examination showed, among others, the abductor hallucis muscle edema after exercises with the DPc device were carried out. It evidences that exercises with the new device activate the muscle. Alignment of the big toes of both feet in groups I and II were obtained with a statistically significant result ( p < 0.05). The percentage progression of correction for HV and I/II IM was calculated. Conclusions: Based on the new correction approach the alignment of the big toe phalanges and the remaining toes was obtained. The passive setup of the tendons with their distal inserts at the level of the big toe phalanges to the correct path of their course with the withdrawal of articular subluxations was obtained. Simultaneously, the big toe's passive correction was dynamically consolidated through a specially selected set of exercises.

Opis:
Introduction: The main goal of the present umbrella review was to provide the most up-to- date and evidence-based results regarding the various treatment options for tennis elbow (TE), which hopefully will significantly decrease the confusions existing in the literature. Furthermore, our study differs from past analytical studies because, as to the best of the authors’ knowledge, is the first to provide independent (not in comparison to other treatment) statistical results regarding the effectiveness of each TE treatment. Materials and Methods: Major medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library, BIOSIS, and EBSCO were searched. The overall search process was conducted in 3 stages. Results: A total of 40 studies met the inclusion criteria and were included in this study. Out of those 40 meta-analyses, a total of 160 primary studies were screened in order to extract the data and perform a statistical analysis. Conclusion: The present umbrella review underlines the efficiency of injection therapies, especially autologous blood, and platelet-rich plasma, while simultaneously proving the ineffectiveness of acupuncture and shock wave therapy as treatments for TE. Furthermore, the value of other known conservative treatment modalities, such as physical therapy, has been demonstrated.

Opis:
Arthroplasty procedures are more frequently performed due to their impact on the quality of life. The aim of this study was to evaluate and analyze the Polish national datasets and registries for hip and knee arthroplasty across Poland in order to describe and understand the challenges for healthcare in an aging society. The study included national data on 83,525 hip or knee arthroplasties performed in 2017. Of those, 78,388 (93.8%, 63.0% females) were primary operations: 66.6% underwent hip replacement surgery (HPRO, mean age 68.43 years, SD 11.9), and 5137 were secondary operations (females: 62.9%), with 75.2% of those being HPRO (mean age 69.0 years, SD 12.0). The mean age of the patients undergoing knee surgery (KPRO) was 68.50 years (SD 8.2). The majority (79.9%) were scheduled. The main reason for hospitalization was arthrosis (84.2% in total, HPRO—76.5%, and KPRO—99.5%), then trauma (15.1%; p < 0.001). In 5137 cases (6.2%, 62.9% females) in revision surgery group, 75.2% underwent HPRO (mean age 69.0 years; SD12.0), and 24.8% KPRO (mean age 68.0 years; SD 10.5). Similarly, 71.1% were scheduled. The main reason for hospitalization was complications (total—90.9%, HPRO—91.4%, and KPRO—89.4%) (p < 0.001). Comorbidities were present (over 80%) with the level of influenza, hepatitis B vaccination, and pre-hospital rehabilitation not exceeding 8% each in both groups. Due to the increasing age of patients, implicating comorbidities, there is a need for better preparation prior to surgery.
