Summary
Bone plugging in below-knee amputation significantly increased muscle blood flow in the tibial stump. This technique enhances blood supply to the quadriceps and triceps surae muscles post-surgery.
Area of Science:
- Vascular Surgery
- Orthopedic Surgery
- Nuclear Medicine
Background:
- Arterial insufficiency often necessitates below-knee amputation.
- Maintaining adequate muscle blood flow in the residual limb is crucial for healing and function.
Purpose of the Study:
- To evaluate the impact of bone plugging in the medullary cavity of the tibial stump on muscle blood flow after below-knee amputation.
Main Methods:
- Muscle blood flow was measured using 99mTc pertechnetate clearance in 31 patients undergoing below-knee amputation.
- Patients were divided into two groups: myoplastic amputation (n=15) and bone plugging of the tibial stump (n=16).
- Measurements were taken pre- and postoperatively.
Main Results:
- Bone plugging of the tibial stump resulted in a two-third increase in muscle blood flow.
- This indicates improved vascularization of the quadriceps and triceps surae muscles.
Conclusions:
- Bone plugging is an effective technique to enhance muscle blood flow in below-knee amputation stumps.
- This method may contribute to better outcomes in patients with arterial insufficiency requiring amputation.
