A Clinical Comparison of Patient-specific 3D Printed Splints Versus Conventional Splints in the Treatment of Distal Radius Fractures.
A Clinical Comparison of Patient-specific 3D Printed Splints Versus Conventional Splints in the Treatment of Distal Radius Fractures.
The goal of this clinical trial is to assess patient reported outcome measures of adult patients who are diagnosed with a distal radius fracture and treated with a patient-specific 3D printed splint as compared to a control cohort.
Patients receive routine immobilization procedure with a patient-specific 3D printed splint instead of the use of a conventional forearm splint after one week of conventional immobilization.
The main study parameters are patient reported outcome measures related to comfort and satisfaction of the medical aid. This will be measured qualitatively with a semi-structured interview and quantitively using questionnaires.
Distal radius fracture (DRF) is a very common injury of the upper extremity. Yearly, over 45,000 patients visit the outpatient clinic with a DRF in the Netherlands. One third of these fractures are non-displaced and two thirds are displaced fractures. The conservative treatment of DRFs includes immobilization of the injured extremity using a conventional forearm cast. These casts do cause all sorts of discomfort during wear and impose life-style restrictions on the wearer. Examples are irritation and itching of the skin, pain from pressure points and inability to shower or swim without a protective sleeve. Emergent three-dimensional (3D) technology enables patient-specific splint design and fabrication. These splints are custom made to accurately fit the individual patient. The material of 3D printed splints is considered lightweight. Moreover, 3D splint design allows an open structure resulting in more ventilation, offering better hygiene and the possibility for wound control. The production of 3D splints can be accomplished with several hardware and software combination. The production process is similar overall and requires several steps. First image data with 3D spatial information of the limb is captured with either a 3D scanner or medical imaging device. The design of the 3D printed splint is further developed using a software application. The 3D splints design data is then exported, and the physical splint is printed using a 3D printer. Depending on material and device characteristics, postprocessing steps are required. The splint may require removal of support, curing and smoothing. If applicable, a closure mechanism is applied.
Currently most implementations of custom made 3D printed splints happen within the framework of case series or feasibility studies. Some previous studies have described on clinical tests from patients with promising results. However, studies are heterogenous in the use of hardware, software, 3D splint design, print materials, fabrication time and costs. Moreover, clinical comparison with conventional interventions remain scare. Therefore, it is challenging to determine the impact of 3D printed splints intervention on the patient with injuries .
The goal of this clinical trial is to assess patient reported outcome measures of adult patients who are diagnosed with a DRF and treated with a patient- specific 3D printed splint as compared to a control cohort. The secondary objectives are:
