PURPOSE: To analyze the clinical outcomes of surgical treatment of distal humerus intercondylar fractures through the transolecranon approach combined with anterior transposition of the ulnar nerve. MATERIALS AND METHODS: Eight patients who had distal humerus intercondylar fractures were included in this study and underwent operative treatment through the transolecranon approach for sufficient operative field with anterior transposition of the ulnar nerve and fixed with reconstruction plate. RESULTS: The results were evaluated using Riseborough and Radin rating criteria. Seven cases of eight cases were achieved good results with flexion contracture less than 30 degrees and forward flexion more than 115 degrees. However, one case was acheived poor result with 40 degrees of flexion contractue and 70 degrees of forward flexion. There were no the compressive ulnar neuropathy. CONCLUSION: We found the transolecranon approach and anterior transposition of the ulnar nerve a viable option for surgical treatment of the distal humerus intercondylar fractures

This study reports a rare case of ulnar neuropathy around the arm with Martin-Gruber anastomosis of a moderate conduction block in the forearm segment and a severe conduction block in the arm segment. Inching tests and ultrasonography showed a lesion between 12 and 14 cm from the medial epicondyle. It is concluded that axilla stimulation may provide diagnostic clues, and inching tests and ultrasonography may be helpful for localizing a lesion.

The arcade of Struthers has been described as a possible cause of ulnar nerve compression in the elbow. This paper reports two cases of ulnar neuropathy caused by the arcade of Struthers. These observations demonstrated the importance of evaluation of the arcade of Struthers in atypical high ulnar nerve palsy.

We found a unique anatomical variant of the distal ulnar nerve, a neural loop encompassing the flexor carpi ulnaris during Guyon's canal exploration. Compression by the flexor carpi ulnaris during active wrist movement was suspected as the cause of ulnar neuropathy. The symptom was relieved after neurolysis and release of surrounding tissue. With regard to the ulnar side wrist pain, which is suspicious for ulnar compression syndrome at the wrist level, the surgeon should always suspect anomalous nerve branch as source of compressive neuropathic pain.

OBJECTIVE: To describe an ultrasonography-guided technique for cubital tunnel injection. METHOD: The ulnar nerves from 12 elbows of 6 adult cadavers were scanned, and the cross-sectional areas of the ulnar nerves, cubital tunnel inlets and outlets were measured by using ultrasonography. All elbows were dissected after an ultrasonography-guided dye injection at the inlet of the cubital tunnel. The dissectors evaluated the spread of dye and the coloration of the nerve and remeasured the cross-sectional areas of the cubital tunnel inlets and outlets. RESULTS: After a real-time visualization of an ultrasonography-guided injection, the ulnar nerves were seperated from the medial groove for the ulnar nerve. All the ulnar nerves of the cadavers were successfully colored with the dye, from the inlet to oulet of the cubital tunnel. The post-injection cross-sectional areas were significantly larger than the pre-injection cross-sectional areas. No significant differences were detected in the post-injection cross-sectional areas of the cubital tunnel outlet and the ulnar nerve as compared with the pre-injection areas. CONCLUSION: Clinicians should consider real-time visualization of ultrasonography for guided injection around the ulnar nerve at the inlet of the cubital tunnel.

Tardy ulnar nerve palsy might develop secondary to nonunion, malunion, or elbow deformity after medial epicondylar fracture of the humerus. We report a case of tardy ulnar nerve palsy following medial epicondylar fracture, treated with excision of bony fragment, neurolysis and relocation of the ulnar nerve.

Cubital tunnel syndrome is the second most common compressive neuropathy. Its diagnosis is largely based on clinical findings. It has been well known that patients with mild to moderate grade of cubital tunnel syndrome have a high chance of spontaneous resolution, while those with severe degree do not. Thus, the former is treated with conservative methods initially, and the latter is indicated for surgical intervention. There are three types of surgical techniques for cubital tunnel syndrome. Of these, in-situ decompression technique has been gaining popularity as it is simpler and shows similar efficacy with less complications compared to other techniques. In this review, we deal with current concepts of the cubital tunnel syndrome pertaining to the primary clinical practice.

Of several possible configurations of pin fixation of a displaced supracondylar fracture of the humerus in children, the medial and lateral crossed pinning technique has been known to provide the greatest resistance to gross rotational displacement. A new technique with ipsilateral two lateral crossed pins was devised so as to avoid the ulnar nerve injury with good stability for fracture site. During the period from 1992 to 1994, 18 children with displaced supracondylar fracture of the humerus were treated by closed reduction and ipsilateral two lateral crossed pinning. Eighty nine percents of the final results were satisfactory. There were no ulnar nerve injuries and fixation loss in all cases from the treatment. This is a safe, simple and reliable technique for providing the good stability of fracture site as well as avoiding the ulnar nerve injury.
