Wound Closure (Allgower) Versus Secondary Open Wound Healing After Removal of the External Fixator (Pinsides)
August 6, 2022 updated by: Reto Babst, Luzerner Kantonsspital
"Wound Closure (Allgower) Versus Secondary Open Wound Healing of the Pin Sites After Removal of the External Fixator: Study Protocol for a Prospective, Randomized Controlled Mono-center Trial"
In this prospective randomized controlled single-center trial, based on a non-inferiority design, the outcome of the treatment of patients are analyzed, whereas in half of the cases the wounds are left open and the other ones are primary wound closed after local debridement after Fixator-Extern is removed.
Although this topic embodies a daily business, there is no standard to be found in literature regarding the treatment of pin sites with closure by either primary or secondary intent.

Detailed Description
In the orthopedic department of the Kantonsspital Lucerne (LUKS) after removal of the external fixator, the pin sites at the tibia and the back of the foot are routinely treated with primary wound closure.
An international survey carried out by the LUKS shows that in comparison to our standard treatment the majority of surgeons left the pin sites open during the healing process.
In order to find a standardized method to treat pin sites we conduct a randomized controlled trial, in which half of the pin site wounds are left open and the other half are treated by primary wound closure after local debridement (Treatment of the first pin-side will be randomized, then alternated treatment of the consecutive pin-sides).
All patients of the study participants are treated within a fixed pre- and postoperative protocol, which includes antibiotic prophylaxis with a single shot of Cefazolin 2g intravenously 30 minutes prior to surgery.
The postoperative pin care includes daily inspection of the pin sites, cleaning the secondary healing wound with Ringerfundin © and disinfection with Betadine ©.
Primary wound closures are dressed with dry gaze bandage.
The following out-patient treatment is provided either by a Spitex support, the family doctor or by the patient himself, depending on the patients compliance.
Regular follow-up consultations at 2, 6, 12, 24 and 52 weeks after surgery ensure an adequate surveillance of the healing process, whereas the examining doctor at the second and last consultation was kept in dark what therapy was chosen for pin sites of the patient.
To objectify the clinical progress the pin sites are photo documented at the consultations at week 2 and 52.
