“…Some researchers believed that center of rotation angulation (CORA) might be a better site for osteotomy, while others recommended meta-to-diaphyseal area. [ 28 - 30 ] Recent studies have shown that the involvement of proximal radioulnar joint (PRUJ) should not be ignored in chronic Monteggia fracture, as it can be an important factor for prognosis. [ 3 , 8 ] In this study, we chose a plane where would be a possible proximal border of a radial notch, as we considered that the interaction between the radial tubercle and the callus during postoperative physical rehabilitation would bring out a notch-like callus for PRUJ reconstruction.…”

Objectives This study aims to evaluate the efficacy of closewedge osteotomy and monorail external fixator in the treatment of chronic Monteggia fracture. Patients and methods Between January 2014 and December 2021, data of a total of 22 patients (14 males, 8 females; mean age: 15.6±5.1 years; range, 6 to 25 years) who suffered from chronic Monteggia fractures were retrospectively reviewed. All the patients were treated for acute angulation of the ulna after osteotomy and gradual angulation for radial head reduction. Range of motion of the elbow and forearm, the angle between the longitudinal axis of proximal radius and the hypothesized Storen’s line (RSA), Visual Analog Scale (VAS), and Mayo Elbow Performance Score (MEPS), as well as Disabilities of Arm, Shoulder and Hand (DASH) score were recorded preoperatively and at the final follow-up. Results Objective parameters were all significantly improved in the aspects of range of motions of the elbow and forearm, and RSA (21.4±4.5° preoperatively and 2.0±1.4° at the final follow-up, t=18.20, p<0.05). The level of pain due to the chronic injury was eliminated, as the mean VAS was significantly lower at the final follow-up compared to preoperative scoring (2.8±2.0 preoperatively and 0.5±0.9 at the final follow-up, t=4.86, p<0.05). The function of the elbow and upper limb was restored, which was indicated by improved MEPS (73.2±12.5 preoperatively and 96.6±6.4 at the final follow-up, t=7.70, p<0.05) and DASH (28.3±6.0 preoperatively and 4.1±2.0 at the final follow-up, t=19.35, p<0.05). No complication was observed. Conclusion Close-wedge osteotomy and gradual lengthening with monorail external fixator in the treatment of chronic Monteggia fracture showed great efficacy. We also provided a specified osteotomy site aiming at PRUJ reconstruction.

“…Surgical procedures that address congenital deformities can also benefit from preoperative 3D models. These models also have wide application in orthopaedic and faciomaxillary practice to address complex malunions, plan relevant osteotomies and correct deformities that require extensive, multiplanar reconstructions. Intraoperative use of bespoke drills and resection guides used in osteotomies can allow depth and angle control, as seen in many successful mandibular reconstructions.…”
