Purpose:
To determine whether the incidence of complications varies between among types of distal phalangeal fractures in a pediatric population.
Methods:
We retrospectively reviewed the medical records and radiographs of patients seen in the pediatric hand surgery clinic from 2011 to 2012 with a diagnosis of distal phalanx fracture. Patients were identified by International Classification of Diseases-Ninth Revision code (816.02 or 816.12). We reviewed 206 charts and included them in the study. Demographic data, location of the fracture, specific diagnosis, mechanism of injury, outcomes, and complications were recorded. The treating physicians clinically identified the outcomes and complications.
Results:
Average age of patients was 7.5 years. Fracture distribution was tuft (37%), mallet (18%), Salter-Harris I/II (13%), shaft (11%), base (11%), Seymour (6%), Salter-Harris III/IV (2%), and tip amputation (1%). Complications occurred in 31% of patients. The highest rates were for Salter-Harris IV (100%), Seymour (62%), and mallet fractures (49%). There was a statistically significant difference in complication rate by diagnosis. The most common complications were infection (22%), stiffness (15%), and nail deformity (13%).
Conclusions:
Complications of distal phalanx fractures in children are frequent. The incidence varies by fracture type, the highest of which are for Salter-Harris IV, Seymour, and mallet fractures. Special care needs to be taken to reduce the complication rates of these common fractures.
Type Of Study/Level Of Evidence:
Therapeutic IV.

Fractures: 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...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
