What Instruments Should Be Prepared for an Examination in Orthopedics

Examination in Orthopedics

The foundational role of orthopedic examinations is to find out the cause of musculoskeletal pain effectively. Whether it's a simple outpatient exam or a more thorough pre-operative examination, the use of appropriate tools significantly improves the accuracy of diagnosis and patient outcomes. Orthopedic therapists, physiotherapists, and medical students should be well-versed in the equipment required to conduct the most efficient and effective examination of the musculoskeletal system.

This guide provides vital tools needed during an orthopedic exam and is organized by function and functionality. From the basic hand tools to the specific equipment employed in assessments of the joints and neurological conditions, each category plays a part in providing a comprehensive clinical evaluation. Let's take an in-depth look at each.

1. Introduction to Orthopedic Examination Instruments

An orthopedic exam is a comprehensive examination of the musculoskeletal system, including bones, joints, muscles, nerves, ligaments, and joints. It helps in diagnosing:

• Fractures
• Arthritis
• Tendon injuries
• Ligamentous tears
• Neuromuscular conditions

The principal goals of the test are:

• Assessing the range of motion
• Analyzing the strength of your muscles
• Detecting joint abnormalities
• The process of identifying deformities and impairments to the nerve

To accomplish this, doctors depend on a mix that includes general diagnostic instruments, orthopedic-specific instruments , and support aids.

2. General Instruments for Physical Examination

C. Tuning Fork (128 Hz or 256 Hz)

It is crucial to differentiate between pain caused by nerves and bone or dysfunction.

6. Orthopedic-Specific Examination Instruments

A. Scoliometer

The test is used to determine the curvature of the spinal column and to screen for scoliosis.

• Tests the Asymmetry in the trunk
• Quick and non-invasive
• Helps to determine Cobb angle during follow-ups.

B. Tape Measure for Limb Length Discrepancy

• Truly length: ASIS to medial malleolus
• The appearing length of the umbilicus from the medial malleolus
• Essential in orthopedic evaluations for children and post-fracture assessments.

C. Plumb Line

The test is used to determine body alignment and posture, specifically in scoliosis, the kyphosis condition, or lordosis.

7. Examination Table and Patient Support Tools

Although they aren't handheld instruments, The following equipment is the basis of an effective orthopedic exam room

A. Adjustable Examination Table

• It should allow for different heights and angles of reclining.

• It helps in identifying the involvement of nerve roots
• Vital in spinal and nerve injury assessments.

C. Joint Range Reference Guides

• Normal joint range values for reference
• It is useful in comparing impaired movements

9. Imaging Support Tools

While not being utilized in physical exams, instruments that help with reviewing images are usually kept close to hand:

A. X-ray View Box or Digital Viewer
