“…The use of 3D printing and modern technology to support complex procedures in the foot and ankle has been published for the management of the type IV tarsal coalition and ankle replacement. 3,6,13,14 The main advantages of PSCG were intraoperative time saving, some improvements in accuracy and safety, and the reliability of the procedure in a teaching hospital. 7 For tarsectomy, 3D planning and PSCG could reduce the risk of overcorrection to an iatrogenic flatfoot.…”

“…7 For tarsectomy, 3D planning and PSCG could reduce the risk of overcorrection to an iatrogenic flatfoot. 9,12 The most recent study about PSCG in the foot was published by Sobrón et al 13 They highlighted the asset of PSCG for osteotomy in a different planned axis that was not linear or out of the axial plane. The aim of PSCG was therefore to limit a slow, progressive, "blind" bone excision in a type III or IV tarsal coalition.…”

“…The aim of PSCG was therefore to limit a slow, progressive, "blind" bone excision in a type III or IV tarsal coalition. 13 The same benefit can be gained by a biplane complex osteotomy of the midfoot, such as tarsectomy, first metatarsal osteotomy, or calcaneal osteotomy when needed. 12,15 The complexity of the cavus foot as a congenital deformity could be comparable to tumor or pelvic pathology.…”

“…As the development of three-dimensional (3D) printing technology, 3D-printed models (3DPM) have gained global popularity owing to their individualization, visualization, and tangibility with actual dimensions and spatial geometry [14,15,16,17,18,19,20]. Previous studies have shown that the use of 3DPM is associated with decreased surgical time and intraoperative X-ray exposure, as well as increased operative accuracy and safety compared to traditional imaging in the treatment of ankle deformities [21,22]. Duan et al [23] found that preoperative planning with 3DPM facilitated accurate drilling of K-wires into the appropriate position, reduced the operation time and intraoperative radiation in 29 patients who underwent subtalar joint arthrodesis.…”

Background: Gradual distraction with external fixators such as Ilizarov frame has been widely used for the treatment of severe postburn ankle contracture (PAC). However, the application of external fixator is complex and conventional surgical planning based on 2D imaging is compromised due to a lack of spatial geometry and tactile feedback. The purpose of this study was to evaluate the surgical planning with patient-specific 3D-printed models (3DPM) for the treatment of PAC with external fixators. Methods: A two-centered retrospective cohort study, composed of consecutive patients who underwent external fixation for the treatment of severe PAC, was implemented. Patients were divided into two cohorts (3DPM group vs. Control group) according to whether 3DPM was used for preoperative surgical planning. The primary outcome variable was operation duration. Other outcome variables included improvement in metatarsal-tibial angle (MTA), range of motion (ROM), American Orthopedic Foot and Ankle Society (AOFAS) scores, and complications. Results: Between January 2008 and June 2018, ten patients with an average age of 23.8±14.1 yeas were treated for PAC at two centers. 3DPM were used for surgical planning in 5 patients. 3DPM group had significantly shorter operation duration than the control group (2±0.3 hours vs. 3.2±0.3 hours, p=0.0001). The comparison of preoperative, after removal of external fixator, and follow-up MTA, ROM, and AOFAS between the 3DPM and control group showed no significant differences. A plantigrade foot was achieved and gait was substantially improved in all patients at the final follow-up. Pin-tract infections occurred in 2 patients (one in each group) during distraction and were treated with wound care and oral antibiotics. Conclusion: The results of this study show that surgical planning using patient-specific 3DPM significantly reduced the operation duration while providing similar improvements in MTA, ROM, and AOFAS scores compared to traditional surgical planning for the correction of severe PAC with external fixators.

“…A un seguimiento promedio de 17.9 meses (rango 12 a 37 meses) ningún paciente presentaba recidiva y se encontraban asintomáticos luego de retornar a la actividad. De manera reciente, Sobrón y sus colegas 16 detallaron más extensamente el uso de biomodelos y guías de corte en esta patología, describiendo algunos aspectos técnicos en coaliciones tipo III y IV, que son aquellas que presentan mayor dificultad durante la resección. En nuestra serie no utilizamos guías de corte.…”
