Summary
Surgical treatment for distal triceps tendon rupture with olecranon osteophyte avulsion significantly improves pain and function. Early surgery and avoiding smoking are key factors for better recovery outcomes in this rare condition.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Traumatology
Background:
- Distal triceps tendon rupture associated with olecranon osteophyte avulsion is a rare injury.
- Limited literature exists on the surgical management and outcomes of this condition.
Purpose of the Study:
- To report a case series on distal triceps tendon rupture with olecranon osteophyte avulsion.
- To evaluate clinical and functional outcomes following surgical treatment.
Main Methods:
- Analysis of patients surgically treated for distal triceps tendon rupture with olecranon osteophyte avulsion (2011-2022).
- Assessment of clinical and radiographic characteristics, pain levels (VAS), and functional outcomes (Q-DASH, MEPS).
Main Results:
- Significant pain reduction observed within 12 weeks post-surgery (mean VAS from 5.8 to 0.8).
- Marked improvement in functional scores (Q-DASH) between 6 and 12 months (mean from 1.9 to 0.2).
- Surgical intervention within 7 days correlated with less residual pain; smoking negatively impacted functional scores at 6 months.
Conclusions:
- Surgical treatment effectively improves pain and function in cases of distal triceps tendon rupture with olecranon osteophyte avulsion.
- Timely surgical intervention, smoking cessation, and patient factors influence recovery.
- This case series provides Level of Evidence IV data on managing this rare injury.
