Late Flexor Entrapment in Neocortex After Pediatric Forearm Fracture: A Case Report

Case:
A pediatric patient sustained an open Monteggia-equivalent fracture treated operatively. Despite uneventful fracture healing, late-onset extrinsic flexor tightness of the index finger occurred. A neocortex developed about the torn ulnar periosteum, entrapping the index flexor digitorum profundus muscle belly. Despite being 5 years postinjury, motion was improved after proximal muscle release.
Conclusion:
Acute flexor entrapment is well-reported in forearm fractures; however, late-onset entrapment inside a neocortex is not. Although early recognition of restricted motion is ideal, even long-standing contractures may be amenable to improvement with appropriate treatment guided by the physical examination.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
