We propose a protocol to invite patients with unicondylar fractures identified from the AMC database to return for evaluation and radiographs in order to collect long term (>10 years) data regarding the outcomes of these rare fractures.

Background summary
To our knowledge only one paper has specifically addressed unicondylar (AO Type
B) fractures of the distal humerus.1 Review of the AO database at the Academic
Medical Center has confirmed that these injuries are particularly uncommon.
This retrospective review has also identified that the vast majority of partial
articular fractures are actually variants of capitellum fractures, also called
*apparent capitellum fractures*, complex articular fractures,
capitellum-trochlea fractures.
A publication of the data from AMC would represent 1) the second paper in the
world literature to address unicondylar/partial articular/Type B fractures as a
group; 2) confirmation from another center that simple capitellum fractures are
rare and most apparent capitellar fracture are very complex articular
fractures; and finally and most importantly, 3) Has the potential to provide
long-term follow-up of these injuries*something that is otherwise very
difficult to obtain.
Study objective
We propose a protocol to invite patients with unicondylar fractures identified
from the AMC database to return for evaluation and radiographs in order to
collect long term (>10 years) data regarding the outcomes of these rare
fractures.
Study design
All patients treated for unicondylar distal humerus fractures in the Academic
Medical Centre in Amsterdam from the first available year of registry in the AO
AMC trauma database from 1974 until 1998, will be invited to return to our
out-patient clinic for a long term follow up (IRB approved).
Standard Elbow Outcome instruments, such as the Mayo Elbow Performance Index,
the Broberg & Morrey Elbow Evaluation and the ASES (American Shoulder and Elbow
Society) Elbow Score, will be used to assess subjective and objective
functional outcome.
The DASH-questionnaire will be used to evaluate funcational outcome from the
patient*s point of view. Standard elbow radiographs will be taken to evaluate
postoperative alignment and arthritis scored according to the system of Broberg
and Morrey.
Study burden and risks
Burden: One time visit to the AMC Amsterdam.
Risk: Very low risk classified as tricial risk for X-photography of the elbow.
