Avascular Necrosis Bone Complication after Active COVID-19 Infection: Preliminary Results.

: The course of SARS-CoV-2 (COVID-19) is still under analysis. The majority of complications arising from the infection are related to the respiratory system. The adverse effect of the viral infection on bone and joint tissue has also been observed.

Surgical treatment of diffuse idiopathic skeletal hyperostosis of cervical spine with dysphagia - Case report.

Introduction: Diffuse idiopathic skeletal hyperostosis of cervical spine can lead to dysphagia.

Presentation Of Case: A 73-year-old male weighing 110 kg and diagnosed with diffuse idiopathic skeletal hyperostosis in cervical spine with dysphagia. Patient manifested local pain of neck, a gradual limitation of spinal mobility.

Prevalence of "red flags" among the internet user with low back pain seeking information on spinal health-a web survey.

Background: In early management of low back pain (LBP) the identification of "red flags" (RFs) plays an important role, as this condition is highly prevalent, and advanced treatment would not be feasible in every case. These alarm signs are designed to detect serious causes requiring prompt interventions, such as malignancy, fracture, inflammation, or cauda equina syndrome. Although their predictive value has been questioned, they are commonly used in clinical practice.

Unusual location of chordoma metastasis.

Background: Chordoma is a rare tumor originating from the remnants of the notochord. The tumor is known as locally aggressive with a strong tendency for recurrence rather than metastasis.

Case Report: We reported on a case of a 47-year-old Caucasian male with a history of sacral chordoma with metastasis to the cicatrix.

Foraminoplastic transfacet epidural endoscopic approach for removal of intraforaminal disc herniation at the L5-S1 level.

Transforaminal endoscopic disc removal in the L5-S1 motion segment of the lumbar spine creates a technical challenge due to anatomical reasons and individual variability. The majority of surgeons prefer a posterior classical or minimally invasive approach. There is only one foraminoplastic modification of the technique in the literature so far.

Failure and success in the treatment of breast carcinoma in men: a case report.

Background: Male breast cancer (MBC) represents a rare cause of vertebral body compression fractures along with severe pain restricting the patient's daily functioning. Limited number of cases, lack of awareness among patients and physicians leading to delayed management, further increase the average age and disease progression at presentation, resulting in a poor prognosis. Additionally, studies on MBC treatment protocols and the use of female algorithms are unavailable.

Reliability and validity of the Polish version of the Core Outcome Measures Index for the neck.

Purpose: Patient reported outcome measures play an increasingly important role in the outcomes research. The Core Outcome Measures Index (COMI) is a short, multidimensional instrument initially developed for the use by patients with low back pain. This study is an evaluation of a Polish version of COMI adapted for neck pain.

Cross-cultural adaptation and validation of the Polish version of the core outcome measures index for low back pain.

Purpose: The core outcome measures index (COMI) is a short, multidimensional outcome scale validated for the use by patients with spinal disorders. It is a recommended instrument in the Spine Society of Europe Spine Tango Registry. The purpose of this study was to produce a cross-culturally adapted and validated Polish COMI.

Validation and cross-cultural adaptation of the Polish version of the Oswestry Disability Index.

Study Design: Validation of a translated, culturally adapted questionnaire.

Objective: To translate and culturally adapt a Polish version of the Oswestry Disability Index (ODI) and to validate its use in Polish patients.

Summary Of Background Data: The ODI is among the most popular questionnaires used to evaluate back pain-related disability.

[The effectiveness of the vertebroplasty in the treatment of the osteoporotic vertebral fractures].

We describe the use of vertebroplasty as an effective method to treat osteoporotic vertebral changes. Scant reports in the literature of national expertise and low penetration of this method in Poland has led the author to conduct their own research demonstrating the effectiveness of the method on the basis of treatments performed in Spine Surgery, Oncology Orthopedics and Traumatology Department W. Dega at University Hospital Poznań, Poland and to collect literature describing the topic.

[Masters of Ireneusz Wierzejewski].

Authors described the figures of outstanding German orthopaedists and the influence they exerted on the development of Polish orthopaedics. Their biggest achievements for the European and global orthopaedic are clarified. The particular attention was devoted to these luminaries of German orthopaedics at whom Ireneusz Wierzejewski, author of modern Polish orthopaedics, began studies, undertook the clinical practice as well as developed his professional interests.

[Neuropathy of medial nerve compression in the elbow].

We write about the difficult clinical aspects of medial nerve compression in the forearm and elbow: Kiloh-Nevin syndrome and pronator-syndrome. We suggest, that some anatomical structures in the forearm can compress the nerves, similar to the ethiology in the carpal tunnel syndrome.

[Current views on the treatment of upper limb compression neuropathies].

The article presents current views about upper limb neuropathies, their treatment and clinical manifestations. The following conditions are described: carpal tunnel syndrome(CTS), cubital tunnel syndrome(CUTS), radial tunnel syndrome, and posterior nervus interosseus syndrome.

[Forearm tumor of the soft tissue inflammatory-like etiology].

We write about case of 60-year-old man with a forearm tumor about 7 cm large. The change revealed to have inflammatory-like etiology. The surgery made a good result for the health and quality of life for the patient.
