This study consists of a retrospective and a prospective part. For each part and in each of 5
clinics, one intraoperative postimplant image (lateral view) of 25 patients with
pertrochanteric fractures will be assessed by 5 surgeons per clinic. There are two
assessments in the retrospective part. a) before an educational intervention, b) after the
educational intervention. The evaluated images at these two timepoints are identical. In the
prospective part, the surgeons apply their new knowledge from the educational intervention.
They perform the positioning of the patient during the intraoperative fluoroscopy and record
the image according to the teaching material. One postimplant image of each patient will be
used for the evaluation.
At all three timepoints of image assessment, a questionnaire with the same set of 7 criteria
(Q1-Q7) for assessing the radiographs is used. The criteria refer to the content of the
educational material.

5 surgeons in 5 clinics will participate including a total of 125 prospective and 125
retrospective cases. This means 25+25 cases per clinic or 5+5 cases treated by each surgeon.
The anonymized images of the surgeon's last 5 patients (retrospective part) and the
pseudonymized images of the next 5 patients meeting the eligibility criteria (prospective
part) will be assessed. Patients are eligible if they are at least 18 years old, have an AO
31-A1, A2 or A3 fracture and were treated with either a Proximal Femoral nail Antirotation
(PFNA), a PFNA- II, a Dynamic Hip Screw (DHS) or a Titanium Trochanteric Fixation Nail System
(TFN).
Individually, the 5 surgeons per clinic review the 25 postimplant intraoperative lateral
images filed for 5 retrospective cases using a set of predefined criteria.
After this first assessment of retrospective cases, the group watches a video and a poster
and has one hour of time to discuss it. The group reviews the 25 cases from the pre-education
step again within a period of maximum 5 days. The data are analyzed at AO Clinical
Investigation and Documentation (AOCID) and provided to the surgeons for data review meeting
where they agree on areas for improvement and set target goals for the prospective series.
For the whole period of the second assessment and the prospective series, the poster is
placed in the area of the operating room.
After patient information/consent, eligible patients are included into the prospective part
of the study and treated with either an intramedullary nail or a DHS. During the surgery, the
surgeons use the newly achieved knowledge to record images.
In the next step, the 5 surgeons per clinic review individually 25 postimplant intraoperative
lateral images of 5 prospective cases using the same set of predefined criteria. The data are
analyzed at AOCID and review by the Imaging Working Group of AO Education.
The data are not transferred between the clinics. The main outcomes will be assessed based on
the "Questionnaire for the assessment of the lateral intraoperative view of the proximal
femur".
This questionnaire consists of seven questions, on image quality (Q1 and Q2; part A) and on
quality of reduction and surgery (Q3 - Q7; part B). Q1 and Q2 allow only "yes/no" answers,
with an option to comment on the answer "no". Q3 to Q5 are based on anatomical assessments
and Q6 and Q7 ask for evaluation of the surgery. There is a "not assessable" answer option
for all questions of part B.
