Clinical Trial Summary
For this retrospective cohort study, medical records of patients treated between 2005 to 2019
with the UTN PROtect and/or ETN PROtect for tibia fractures or tibia revision cases will be
examined. In comparison to this cohort, patients who received an uncoated tibia nail are
examined as well. Demographics, pre-surgical health status, details on fracture type or on
revision, treatment decision and surgery details, postoperative reoperation and revision,
surgical site infections, time to union, and adverse events will be registered. In a
subgroup, additional information including clinical outcomes and patient satisfaction will be
assessed by clinical exam. Patients who still carry a nail and feel discomfort at the
surgical site or present with a medical condition which demands an imaging will receive an
x-ray of the tibia. The xray is not part of the standard study protocol.
Description:
Primary Objective:
The primary objective is to assess the proportion of patients who experienced a surgical site
infection. Surgical site infection is defined as either deep or superficial. The presence of
tibia infection will be defined by the criteria of CDC.
Secondary Objective(s):
- Proportion of patients with reoperation (secondary procedures)
- Bone union (until radiographically healed)
- Proportion of patients with complications / Adverse Events related to implant or surgery
- Only Subgroup: WOMAC-Score, AOFAS, SF36, EQ5D.
Hypothesis and Statistical considerations and estimated enrollment:
We hypothesize that with the use of antibiotic coating implants like the ETN/ UTN-PROtect the
risk of implant-associated infections and osteomyelitis is reduced in treatment of Tibia
fractures or in cases of revision surgery in the tibia. In a retrospective manner the
implanted gentamicin-coated and uncoated tibia nail procedures are evaluated. In the subgroup
of patients with a currently implanted gentamicin-coated nail the incidence of surgical site
infection and implant-associated infections will be assessed prospectively.
This study is exploratory in nature. Therefore, there is no formal statistical hypothesis and
no formal sample size calculation. Approximately 620 tibial shaft fractures are expected to
be included in the 12 months enrollment period.
Data will be analyzed with the use of simple summary statistics. Depending on the volume and
quality of the collected data, different statistical analyses will be applied. Exploratory
analyses will be conducted to investigate relationships between the different treatment
options and the outcomes.
