Claw hammer technique for extraction of knives

Area of Science:

• Trauma Surgery
• Vascular Imaging

Background:

• A deeply embedded knife presented a significant removal challenge.
• Standard removal techniques were insufficient due to the depth and potential vascular involvement.

Observation:

• A knife was lodged deeply in a patient's shoulder.
• Initial attempts at removal were difficult.
• A hammer claw was utilized to provide leverage under the knife's hilt.

Findings:

• The improvised leverage technique facilitated the successful removal of the knife.
• Post-withdrawal angiography revealed the extent of extravasation.
• Angiography proved crucial for evaluating vascular injury post-removal.

Implications:

• This case highlights an effective, low-cost method for removing deeply embedded objects.
• Post-withdrawal angiography is essential for assessing vascular damage after removing penetrating trauma.
• This technique may be applicable to similar penetrating injuries.
