# Periosteal nerve blocks for distal radius and ulna fracture manipulation—the technique and early results

## TL;DR

A new technique using local anesthesia for nerve blocks near forearm fractures provides effective pain relief and successful fracture manipulation in most patients.

## Contribution

A novel proximal periosteal nerve block technique is introduced for distal forearm fracture manipulation.

## Key findings

- 95% of patients had successful fracture manipulation without further treatment.
- 83% of patients reported the procedure as painless.
- No direct complications from the nerve blocks were observed.

## Abstract

We present a pilot series of patients with distal forearm fractures manipulated following a proximal periosteal nerve block with local anaesthesia.

This is a novel technique which can be utilised in adults and children and is described herein.

With a median of 40 years (range 10–81 years), 42 patients (16 children) with distal radial and ulnar fractures were included. Of these patients, 40 underwent periosteal blocks in the emergency room or fracture clinic; 2 were already inpatients. Fractures were manipulated routinely and immobilised with plaster. Mobile fluoroscopy was not used for patients in the emergency department or fracture clinic.

Of the 42 patients, 40 patients (95 %) had successful fracture manipulation and did not require subsequent treatment. Two patients (5 %) needed subsequent surgery, one for K-wire stabilisation of their fracture and the second for volar plate fixation. The procedure was described as painless in 35 (83 %) patients (visual analogue scale/VAS score 0), with 6 (14 %) suffering minimal pain (VAS 1–3). In the 12–16-year age group, 15 patients (94 %) described the manipulation as painless; 1 patient described the procedure as minimally painful. No additional analgesia of any kind was given. There were no direct complications from any of the periosteal nerve blocks.

Local anaesthetic periosteal nerve blocks injected proximally to the fracture sites are a simple and yet very effective new technique which provide good/excellent analgesia and facilitate the reduction of distal radial and ulnar fractures.
