RESUMO
Background: The one-bone forearm procedure has been considered as a potential treatment for severe forearm deformities. However, its primary limitation lies in the elevated risks of nonunion and infection. In order to enhance union rates, a technical modification was introduced, aiming not only to establish end-to-end radio-ulnar fixation but also to incorporate an additional overlay and fixation between the proximal and distal radius osteotomy stumps. This technique, initially applied in a heterogeneous patient population including individuals with neurological, tumoral, and congenital conditions, yielded promising results, achieving a consolidation rate of 100% and enabling supination corrections of up to 120°. Methods: In this study, we present a retrospective cohort of 28 patients, with an average age of 9 years, all afflicted by forearm supination contracture exceeding 90° secondary to neonatal brachial plexus injury. These patients underwent treatment with the modified technique. Results: The mean correction achieved in forearm rotation was 116°, and the average follow-up period extended to 43 months. Remarkably, all patients exhibited bone union within an average period of 6.6 weeks, without any complications. Conclusion: Our findings underscore the efficacy of this modified technique, which enables substantial rotational corrections, boasts a high union rate, and maintains a low incidence of complications. This approach is particularly valuable for young patients suffering from neonatal brachial plexus injury with severe fixed supination deformities. Case series Level of evidence: IV.
RESUMO
PURPOSE: The purpose of this study was to describe a technique of end-to-end rigid fixation of the distal radius to the proximal ulna. The shortening and radioulnar overlap in this technique yield a high union rate, large corrections, and few complications. METHODS: This retrospective chart review from 2 centers was undertaken in 39 patients (40 forearms) who underwent one-bone forearm operations between 2005 and 2019. There were 25 male and 14 female patients, with a mean age at surgery of 9.7 years (range 3 to 19 years; SD, 4.5 years). The diagnoses included brachial plexus birth injury, spinal cord injury, arthrogryposis multiplex congenita, cerebral palsy, ulnar deficiency with focal indentation, multiple hereditary exostosis, acute flaccid myelitis, and tumor. RESULTS: The average follow-up was 33.5 months (1.2-110.1 months; SD, 27.1 months). The 36 forearms in supination had an average supination contracture of 93° (range, 15° to 120°; SD, 15.4°). The 4 pronated arms had an average pronation contracture of 80° (range, 50° to 120°; SD, 29.2°). The average postoperative position was 22.8° of pronation (range, -15° to 45°; SD, 12.9°). The average correction obtained with our technique was 113° (range, 20° to 145°; SD, 22.9°). Radiographic union was demonstrated in 32 (80%) of the one-bone forearms by 10 weeks, 39 (97.5%) by 16 weeks, and 40 (100%) by 24 weeks. One patient had peri-implant fractures prior to union. No forearms required reoperation for nonunion. CONCLUSIONS: One-bone forearm performed with this technique allows reliable healing and a large degree of correction. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: The one-bone forearm arthrodesis has been performed to change the position of the forearm in children with fixed supination deformity due to upper extremity neurologic deficit. In this article, we present a retrospective review of children with late obstetric brachial plexus palsy who underwent palliative surgery to correct severe supination contracture by one-bone forearm osteodesis and biceps re-routing. This technique has not been described previously. MATERIALS AND METHODS: In this retrospective study, four consecutive patients with upper extremity weakness and severe supination contracture who underwent forearm osteodesis in neutral or slight pronation and biceps re-routing. The average age of patients at the time of surgery was 12 years six months (range, 7-14 years). RESULTS: The average follow-up was one year ten months (range, 1 year 6 months to 2 years 7 months). The rotation of the forearm set in neutral (3 patients) and 15° pronation (1 patient). No patients noted adverse effects on the shoulder, elbow or wrist, and none missed having forearm rotation. CONCLUSIONS: One-bone forearm osteodesis and biceps re-routing technique should be considered in some patients with fixed forearm supination deformity and concomitant severe pronation deficit. In this group of patients, repositioning the forearm in a more pronated (or less supinated) position may improve the use of that extremity in activities of daily living. The surgical technique is fairly simple and can be done in a single procedure.

Background: The objective of this study was to review the outcomes of patients who underwent one-bone forearm (OBF) reconstruction. Methods: A retrospective review of patients who underwent OBF surgery between 1994 and 2014 was undertaken. Patient demographics, etiology, associated injuries, number of surgeries prior to OBF surgery, surgical details, and postoperative information were collected. A telephone interview was conducted at final follow-up, including a Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire, a 10-point scoring system used by Peterson et al, and a series of questions concerning pain and patient satisfaction. Results: There were 6 males and 2 females with a mean age of 44 years (range, 20-66 years). All patients had traumatic etiology, with 6 having open wounds and 2 having closed wounds. All patients had union with a mean follow-up of 83.6 months (range, 16-218 months). The mean pain score was 3 (range, 0-8), of which 3 were painless (score 0). The mean QuickDASH score was 39 (range, 7-75), and 4 patients had good or excellent results according to the 10-point score system used by Peterson et al. All patients were satisfied with the result. Five of 8 had complications related to soft tissues that were residual from their prior injuries and surgeries. One patient had post healing fracture requiring revision fixation and 1 had a postoperative infection requiring parenteral antibiotics. Conclusions: OBF surgery is an effective salvage procedure for complicated forearm instability, particularly after trauma. While union rates are high, complications are typically related to pain and soft tissue secondary to the previous injury and reconstructive procedures.
