TWO CLASSIFICATIONS FOR SURGICAL WOUND HEMATOMA AFTER TOTAL HIP REPLACEMENT

Area of Science:

• Orthopedic Surgery
• Medical Diagnostics
• Postoperative Care

Background:

• Wound hematoma is a common complication following total hip replacement.
• Accurate classification of hematoma is crucial for effective patient management.
• Existing subjective methods for hematoma assessment may lack consistent reliability.

Purpose of the Study:

• To compare the reliability of two distinct classification methods for wound hematoma.
• To evaluate subjective versus objective (mathematical) approaches for grading hematoma severity.
• To determine the most dependable method for assessing wound hematoma post-total hip replacement.

Main Methods:

• Prospective cohort study of patients undergoing total hip replacement for osteoarthritis.
• Two experienced surgeons independently classified wound hematoma from 75 postoperative images, twice.
• Subjective classification used four categories; objective classification used mathematical area calculation via a grid.

Main Results:

• Subjective classification showed >70% intra-rater agreement but poor to moderate inter-rater reliability.
• Objective classification, based on mathematical area measurement, demonstrated good to excellent intra- and inter-rater reliability.
• The objective method proved significantly more reliable for assessing wound hematoma.

Conclusions:

• Objective classification of wound hematoma after total hip replacement offers superior intra- and inter-rater reliability.
• This mathematical classification system can be a valuable tool for orthopedic surgeons and healthcare providers.
• The findings support the use of objective measurements for consistent and reliable hematoma assessment in clinical practice.
