Incomplete intertrochanteric fractures: imaging features and clinical management

Area of Science:

• Orthopedic surgery
• Radiology
• Medical imaging

Background:

• Incomplete intertrochanteric fractures represent a distinct injury pattern.
• Accurate diagnosis is crucial for appropriate management and patient outcomes.

Purpose of the Study:

• To detail the imaging characteristics of incomplete intertrochanteric fractures using magnetic resonance (MR) imaging.
• To compare MR findings with conventional radiography.
• To review treatment strategies and outcomes for this fracture type.

Main Methods:

• Retrospective review of 31 patients diagnosed with incomplete intertrochanteric fractures via MR imaging.
• Comparison of MR findings with radiographic data in 30 patients.
• Analysis of fracture characteristics, treatment modalities (surgical vs. conservative), and functional follow-up.

Main Results:

• Radiographic and MR findings showed poor correlation; radiography missed most incomplete intertrochanteric fractures.
• Fracture characteristics (length, involvement of greater trochanter, midline crossing in axial plane) were similar between surgical and conservative groups.
• Fractures crossing the coronal midline were more frequent in the surgically treated group (50% vs. 23%).
• Surgical treatment resulted in a 2-day shorter time to ambulation, with no significant difference in subjective functional status at follow-up.

Conclusions:

• Incomplete intertrochanteric fractures are a unique subset of intertrochanteric fractures.
• MR imaging is essential for unequivocal diagnosis of these fractures.
• While surgery may expedite ambulation, functional outcomes appear comparable to conservative management in the short term.
