A computer tomography-based anthropomorphic study of forearm osteology: implications for prosthetic design

ABSTRACT BACKGROUND: The aim of this study was to accurately establish the variability in anatomy radius and ulna context design an intramedullary nail for both bones METHODS: Forearm computed tomography scans were used measure specific internal external adult patients. Patients with fractures or dislocations involving either and/or excluded RESULTS: A total 97 scans, comprising 84% male 16% female patients, included. mean length 238.43±18.38 mm (95% CI 234.60-241.74 mm). curvature arc a 561.43±93.49 543.09-580.78 smallest measurement canal width 5.17 4.87-5.47 showed 259.90±19.88 255.89-263.91 4.80±1.30 4.53-5.87 proximal shaft angle 11.39±3.30° 10.76-12.82° CONCLUSION: This scan-based anthropomorphic has identified novel anatomical features associations human forearm bones. information will be manufacture anatomic devices better manage pathology Level evidence: 4 Keywords: radius, ulna, anatomy, osteology, curvature,
