“…In addition to the benefit from personalized design and use of lightweight materials for 3D printing, the novel cast is more fashionable and portable as well. Although 3D printing had made advances in the development of casting techniques, most published works for application of 3D-printed casts were still in the concept stage or initial phase [ 8 – 10 ], speaking to the need for experimental data and clinical experiences.…”

Objective. This pilot study is aimed at investigating the mechanical characteristics of a cast-wrapped fractured forearm and performing a clinical comparative study of our own developed 3D-printed orthopedic cast. Methods. An integrated finite element (FE) model including a forearm and a 3D-printed cast wrapping the forearm was created. The distal radial ulna in this model was cut through to mimic the bone fracture. A 400 N force and 1 Nm rotation moment, which were much larger than the loading conditions encountered in daily life for a human being, were applied on the palm. We conducted a comparative clinical study by using statistical assessment. 60 patients with forearm fractures were selected and treated with manual reduction and external fixation cast. All patients were divided into three groups with equal members (20): (a) 3D-printed external cast group, (b) traditional plaster external fixation group, and (c) splint external fixation group. The clinical efficacy, wrist function, and patient satisfaction were scored and compared. Results. In the condition of 400 N loading, the fracture displacements in anterior-posterior (AP), posterior-anterior (PA), medial to lateral (ML), and lateral to medial (LM) compression directions were 1.2648, 1.3253, 0.8503, and 0.8957 (mm), respectively, and the corresponding fracture stresses were 4.5986, 3.9129, and 5.0334, 7.9197 (MPa), respectively. In the inward (IR) and outward (OR) rotations, the fracture displacements were both 0.02628 (mm), and the corresponding fracture surface stresses were 0.1733 and 0.1723 (MPa), respectively. In the clinical efficacy, wrist function, and patient comfort evaluation, the total scores of group A were both higher than those in groups B and C (P<0.05). Conclusion. A 3D-printed orthopedic cast was capable of exerting appropriate mechanical correction loads on specific areas to maintain optimal alignment of a fractured forearm and thus could achieve the favorable clinical efficacy and patient comfort.

“…Graham et al evaluated the functionality of 3D-printed orthoses compared to conventional immobilization in adults [12]. While immobilized in either a short-arm fiberglass cast or a 3D-printed orthosis, volunteers were assessed with both the Jebsen Hand Function Test (JHFT) and Patient-Rated Wrist Evaluation (PRWE).…”

“…Up to date, no highquality clinical trial was able to demonstrate the noninferiority or even superiority concerning wearing comfort or clinical outcome compared to conventional plaster casts and splints. Several in vitro [23,24] and in vivo studies [25][26][27][28][29] highlight the safety and effectiveness of customized 3D-printed forearm casts. These trials indicate a good patient satisfaction due to light, breathable and waterproof splints.…”

Three-dimensional (3D) printing is spreading in hand surgery. There is an increasing number of practical applications like the training of junior hand surgeons, patient education, preoperative planning, and 3D printing of customized casts, customized surgical guides, implants, and prostheses. Some high-quality studies highlight the value for surgeons, but there is still a lack of high-level evidence for improved clinical endpoints and hence actual impact on the patient’s outcome. This article provides an overview over the latest applications of 3D printing in hand surgery and practical experience of implementing them into daily clinical routine.

Conventional vs 3-Dimensional Printed Cast Wear Comfort

Abstract: Both casting techniques demonstrate similar objective function based on the JHFT. Patient satisfaction, comfort, and perceived function are superior in the 3D printed casts.
