Introduction: Haematoma Block Technique Understanding
In emergency and orthopaedic environments, a haematoma block is a commonly utilised treatment to alleviate discomfort during fracture manipulation. Targeting the periosteum, it entails injecting a local anaesthetic straight into the fracture haematoma, therefore greatly lowering pain. Treating dorsally inclined distal radius fractures, sometimes referred to as Colles’s fractures, this approach is especially successful.
This article offers a thorough review of the haematoma block technique together with relevant clinical issues, benefits, and when and how it should be applied.
Define a Haematoma Block
A haematoma block is a local anaesthetic injection into the haematoma developing around a broken bone. The aim is to anaesthetize the periosteum, the sensitive tissue covering the bone, therefore allowing clinicians to control the fracture with least disturbance.
Particularly for distal radius fractures, one of the most common injuries seen in trauma patients, this approach has evolved as a preferred choice because of its simplicity, low invasiveness, and efficacy.
Use a Haematoma Block When
Usually used for the reduction of a dorsally tilted distal radius fracture—also known as a Colles’ fracture—this approach is most effective. The approach greatly lessens pain, enabling the practitioner to relocate the bone fragments without using general anaesthesia.
Since the anaesthesia may take up to 15 minutes to fully affect, time and patience are absolutely vital. Rushing the procedure might jeopardise the success of the manipulation as well as patient comfort.
Detailed Guide to the Haematoma Block Technique
1. Point Out the Fracture Site
Starting on the dorsal side of the wrist, softly palpate. Look for a hump from the distal fragment leaning rearward; this is your anatomical landmark for needle placement.
2. Get Ready for Skin
To reduce infection risk, completely sterilise the area. Keep rigorous aseptic method all through the operation.
3. Needle Insertion
Start the needle at a 30-degree angle pointed distally just proximal to the hump.
Start with a tiny skin wheal under local anaesthetic.
Advance the needle slowly, penetrating anaesthetic along the path.
4. Verify Needle Positioning
Once reaching the fracture site, softly aspirate. Unlike venous or arterial flashbacks, this is predicted if you observe a flashback of dark haematoma blood, therefore confirming appropriate placement.
5. Presume the Anaesthetic
Slowly inject 10 mL of 1% lidocaine using a fanning motion to distribute it around the haematoma.
Haematoma Block: Minimally Invasive with Low Systemic Effects
- Stays away from general anaesthesia hazards
- Provides instantaneous pain relief for reduction of fractures
- Fit for emergency rooms and reasonably priced
- Suggested approach for older patients or those having comorbidities
Important Factors to Consider
- Wait the entire fifteen minutes to start the anaesthesia
- Underline aseptic conditions all through the operation
- Look for any indications of local infections or problems
- Not appropriate for those allergic to lidocaine or open fractures

Conclusion:
Particularly in relation to Colles’ fractures, the haematoma block is a dependable and simple approach for obtaining local anaesthesia during fracture manipulation. It can provide great patient comfort with correct technique and timing, therefore enabling efficient bone realignment without resorting to more intrusive treatments.
