Purpose: Our aim was to examine the outcome of an elbow check-up system for youth baseball players. In particular, we investigated the nature of elbow injuries in youth baseball players with elbow pain and ultrasonographic findings of the capitellum. Materials and Methods: A total of 1605 players participating in the regional summer championship in July 2013 underwent a questionnaire survey, physical examination, ultrasound imaging, and radiographic examination. Results: A total of 499 (31.1%) players reported episodes of elbow pain, of whom 320 (64.1%) had abnormal findings on physical examination, and 115 (35.9%) agreed to undergo radiography. Among them, 98 (85.2%) exhibited radiographic abnormalities. On the initial ultrasonography screening, 60 (3.7%) players had an abnormal finding and 55 (91.7%) agreed to undergo radiography. Among them, 26 (47.3%) were found to have osteochondritis dissecans (OCD) of the capitellum on radiographs. Conclusions: About 30% of youth baseball players had episodes of elbow pain, and 64.1% of players with elbow pain had abnormal findings on physical examination. Furthermore, 85.2% of subjects who underwent radiographic examination exhibited radiographic abnormalities. About 4% of young baseball players had an abnormal finding on initial ultrasonography screening, and nearly 50% of them had OCD of the capitellum on radiographs. J. Med.

Percutaneous endoscopic surgery for the lumbar spine, which was established in the last decade, requires only an 8-mm skin incision and causes minimal damage to the paravertebral muscles; thus, it is considered to be a minimally invasive technique for spinal surgery. It has been used to perform percutaneous endoscopic discectomy via two main approaches: the TF approach is a posterolateral one through the intervertebral foramen and can be done under local anesthesia; the IL approach is a more traditional one through the interlaminar space and is difficult to perform under local anesthesia. Recently, these techniques have been applied for lumbar spinal stenosis (LSS), the TF method for foraminal stenosis under local anesthesia, and the IL method for central and lateral recess stenosis under general anesthesia. In this study, using a fresh human cadaver model, we performed simultaneous decompression of the lateral recess and foraminal stenosis at L4-5 using the TF approach. Computed tomography confirmed enlargement of the lateral recess and intervertebral foramen. This technique, which can be performed under local anesthesia, should benefit elderly patients with LSS and poor general condition due to multiple comorbidities. Finally, we introduce the concept of percutaneous transforaminal ventral facetectomy using a spinal percutaneous endoscope. J. Med. Invest. 64: 1-6, February, 2017
