Conventional Versus Computer-Assisted Corrective Osteotomy of the Forearm: a Retrospective Analysis of 56 Consecutive Cases

Patient-specific plate for navigation and fixation of the distal radius: a case series

“…We recommend carrying out a randomized controlled trial for further evaluation of the method and to quantify more parameters such as the ease of surgery and the overall costs including possible revision surgery and aftercare. This could confirm the finding of Bauer and coworkers [ 41 ] who reported that the use of patient-specific instruments helped to reduce the time of surgery, which we could not investigate in our study. We also did not report long-term follow-up results, which may affect postoperative complications, such as the number of revision surgeries.…”

Corrective Four-fold Osteotomy of The Forearm Performed with 3D-Planning and Patient-Specific Guides

“…Computer-assisted 3D planning is an increasingly utilized method permitting exact quantification of the malunion and generation of patient specific guides. Whilst translation of the preoperative 3D data to correct a malunion can be challenging, comparative studies with conventional osteotomies have demonstrated favorable results regarding accuracy, surgery time and functional outcome [6,9]. The complexity of the osteotomies may vary strongly, ranging from single-cut osteotomies to multiple, composite osteotomies, in which additional rotation of fragments is used for correct anatomical positioning [10].…”

“…Accurate reconstruction is essential as a statistically significant relationship has been found between mal-positioning and clinical outcome [4,5]. Additionally, it has been demonstrated that standard anatomical plates may lead to considerable positioning errors in individual patients [6]. Threedimensional (3D) planned patient-specific guides and implants are increasingly valuable, allowing for precise corrective osteotomies of complex multiplanar forearm deformities [7,8].…”

Early Correction of Distal Radius Partial Articular Malunion Leads to Good Long-term Functional Recovery at Mean Follow-up of 4 Years

“…The use of these systems, while efficacious, may add to the surgical cost, especially when custom jigs are required to perform the osteotomy. 10,16 Bauer et al 2 found that the additional cost of computer-assisted osteotomy for fractures of the forearm is $2415 per case, which includes bilateral CT scans, manufacturing of patient-specific instruments, and other fees. The authors reported shorter operative time, shorter time to consolidation of the osteotomy, but similar clinical outcomes compared with conventional osteotomy.…”

“…The authors reported shorter operative time, shorter time to consolidation of the osteotomy, but similar clinical outcomes compared with conventional osteotomy. 2 The use of these systems is recommended for complex malunions for which plain radiographs and CT scans provide insufficient information for planning the corrective osteotomy. 1 All cases in our series were partial articular malunions that commonly result from shearing injuries.…”
