Insights
This study on pediatric peripheral nerve injuries found that median and radial nerve injuries have a good prognosis, while ulnar nerve injuries fare poorly. Surgical exploration is recommended at 6 months if conservative treatment fails.
Area of Science:
- Pediatric surgery
- Neurology
- Traumatology
Background:
- Peripheral nerve injuries in children's upper limbs are often trauma-related.
- Understanding injury types, locations, and outcomes is crucial for effective treatment.
Purpose of the Study:
- To validate a therapeutic approach for pediatric upper limb peripheral nerve injuries.
- To determine optimal waiting times for surgical exploration of these injuries.
Main Methods:
- A case series analysis of 105 children with peripheral nerve injuries.
- Evaluation included lesion type, nerve injury site, motor/sensory outcomes, recovery time, and surgical results.
- Treatment strategies involved immediate repair for open injuries and delayed surgery for closed injuries.
Main Results:
- Open injuries (Sunderland V) were treated with direct suturing, grafts, or tubules.
- Closed nerve injuries required a waiting period before surgical intervention.
- Median and radial nerve injuries showed favorable outcomes, unlike ulnar nerve injuries.
- Surgical intervention was suggested at 6 months post-injury if no clinical improvement was observed.
Conclusions:
- Prompt surgical intervention is recommended for open injuries.
- A 6-month waiting period is suggested for closed injuries before surgical exploration, especially if conservative measures fail.
- Early skeletal fixation is vital for fractures with potential nerve involvement.
Abstract:
Our series includes 105 children with peripheral nerve injuries of the upper limb due to trauma. The aim of this study is to validate our therapeutic approach to peripheral nerve injuries of the upper limb in children and to identify the suitable waiting time before surgical exploration. Case series examination included evaluation of (1) type of lesion; (2) topographical site of nerve injury; (3) motor and sensory outcome; (4) recovery time; (5) results after surgery. Open injuries (Sunderland V) received immediate treatment with direct suturing or nerve grafts or biological tubules in case of loss of nerve substance. After closed nerve injury, a waiting period of variable duration should precede surgery. Most of the cases had peripheral nerve injuries associated to fracture and cutting lesions followed by injuries due to other causes. Open or closed injuries of the median and radial nerves had a generally favorable prognosis, whereas ulnar nerve injuries (both isolated and associated) had a poor prognosis. Stable skeletal fixation is essential in fractures at risk of nerve involvement. During nerve exploration, secondary surgery interventions were never associated. In the absence of adequate clinical and instrumental response, the authors suggest to resort to nerve surgery at 6 months from injury to accelerate recovery time. Secondary surgery should be delayed as patient's recovery time can be very long. (c) 2009 Wiley-Liss, Inc. Microsurgery, 2009.
