Background:
Most common types of coalitions are Calcaneonavicular (CN) and
Median Bar (MB). These are classified as a bony coalition and a partial fibrous or
cartilaginous type. The condition may cause pain and decreased mobility in the
subtalar joints.
Purpose / Aim of Study:
A retrospective study of the outcome after resection
of tarsal coalitions in children.
Materials and Methods:
Using the Danish medical database, patients with
the diagnosis Tarsal Coalition (DQ668A) from 2006 till 2014 treated at Aarhus
University Hospital was searched. In addition, 13 operation codes were used to
search for patients, with a Tarsal Coalition but who were registered with a dif-
ferent diagnosis. Patients, receiving surgical treatment between the age of 5
and 16 in the year 2006 till 2014 were included in the study. The primary out-
come was defined as the number of re-operations performed or planned after
initial resection of tarsal bone. Furthermore, the patients were post-operative
subjectively classified as better and worse or unchanged, in comparison to prior
to the operation.
Findings / Results:
24 feet in 18 children were included in study with a mean
follow-up of 11 months. Patients were divided into two groups of coalitions, CN
in 15 feet, and MB in 9 feet. Three CN feet underwent additional surgery (re-
section of relapsed bridge n= 3, Arthrodesis n=0) compared to 2 feet in the MB
group (resection of relapsed bridge n= 0, Arthrodesis n=2). In the CN group, 11
feet were described as better and 4 as worse or unchanged. In the MB group, 6
feet were described as better and 3 as worse or unchanged.
Conclusions:
Overall 80 % of the feet improved after surgery, which is in ac-
cordance with previous literature. Adiditional surgery was needed in 20 % of the
cases. Before surgery, patients should be informed of the relatively high risk of
additional surgery.
