Background:
A small number of patients treated with minimally invasive correction of pectus excavatum recur after bar removal. This risk appears to be greater in younger children who continue to grow following bar removal.
Methods:
We propose the use of wrist films to determine skeletal maturity and delay bar removal until it is completed. This is not possible in very young patients (less than 14 years of age) or necessary in patients older than 19.
Results:
In the 14-year to 18-year age group, we have used wrist films to determine skeletal maturity in 25 patients. Ten patients (age 14-18) demonstrated full maturation, and their bars were removed at 2 years. Five patients had films that demonstrated nearly closed growth plates, and those bars were removed 6 months later (2.5 years post-insertion). Ten patients had 2 sets of films taken, initially at 2 years post-operation demonstrating open growth plates. Films 12 months later showed skeletal maturation. Their bars were removed at 3 years post-operation. There were no recurrences with an average follow-up of 3 years.
Discussion:
Radiographic determination of skeletal maturity may be used as a guide to the timing of bar removal following the correction of pectus excavatum.

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...

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...
