About this study

Official title: Prevalence of Work-Related Musculoskeletal Disorders Among Orthopedic Surgeons: a Cross-Sectional Study

The investigators investigated the prevalence of WRMSDs in Egyptian orthopaedic surgeons.

Read the detailed description

Work-related musculoskeletal disorders (WRMSDs) are syndromes characterized by soft tissue pain, stiffness, swelling, fatigue, and lack of control. The National Institute for Occupational Safety and Health (NIOSH) defined Musculoskeletal Disorders (MSDs) as an injury that affects a part of the musculoskeletal system encompassing bones, nerves, tendons, ligaments, joints, cartilage, blood vessels, and spinal discs.

Studies have shown that 60 % to 90% of all specialty surgeons suffer from pain and stiffness in their neck, back, or shoulders.

Physical occupational hazards associated with orthopedic surgery have raised growing concerns. The orthopedic surgery field exposes surgeons to a range of serious risks and imposes tremendous physical and emotional strain.

The Nordic Musculoskeletal Questionnaire (NMQ) was developed by Kuorinka et al. 1987. It is an easy, well-structured questionnaire comprising the whole body by describing nine functional sites for both sides: upper and lower limbs, neck, and lower back. It integrates questions on individual symptoms and activity constraint levels in the previous 12 months.

Statement of the Problem: The study will answer the following research question: What is the prevalence of Work-related musculoskeletal disorders among Egyptian orthopedic surgeons? Purpose of the study: This study will assess the prevalence, characteristics, and impact of work-related musculoskeletal disorders among Egyptian orthopedic surgeons.

Significance of the study: After reviewing the available previous published studies, it was found that there is limited research for both prevalence \& ergonomic assessment considering Egyptian orthopedic surgeons. Ergonomic guidelines are often not followed in the operating theatre design and layout due to a lack of awareness. To the best of our knowledge, no study has evaluated the prevalence of MSDs among Egyptian orthopedic surgeons, although work-related injuries constitute more than 60% of all occupational illnesses.

Currently, there is a knowledge gap regarding the prevalence of WRMSDs among Egyptian orthopedic surgeons. Therefore, the current study aims to assess it, explore the types of WRMSDs, and identify the risk factors for developing WRMSDs among Egyptian orthopedic surgeons.

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prevalence of WRMSDs (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07562126, which also lists 22 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
