Does a line drawn along the radial shaft miss the capitellum in 16 % of radiographs of normal elbows?
The RCL does not invariably bisect or fall within the middle third of the capitellum in normal pediatric elbows. Therefore, an abnormal RCL is suggestive but not pathognomonic for injury such as Monteggia fracture. An RCL drawn along the radial shaft will miss the capitellum in 15.6% of elbows. The most consistent RCL is drawn along the radial neck on the lateral view. Patient variables such as age and sex should be considered in the ability of the RCL to identify elbow injury.
The cartilage-connecting hydroxyapatite prosthesis with a spearhead was found to restore hearing to a satisfactory level. The extrusion rate was relatively low. The cartilage-connecting hydroxyapatite prosthesis with a spearhead is an effective ossicular implant and offers an attractive alternative for ossicular reconstruction, particularly for total ossicular reconstructions.
