Tardy Ulnar Nerve Palsy Caused by Post-Traumatic Elbow deformities: Seung koo Rhee, seok Whan Song, Hwa Sung Lee, Ho Tae Kim; J Korean Soc Fract 1998;11(2):420-426. Published online April 30, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.2.420

Abstract PDF: Thirty-five patients with tardy ulnar nerve palsy caused by cubitus valgus (33 cases0 and varus (2 cases) deformities were retrospectively studied. All patients had a history of old fracture on the distal humerus during childhood. The mean interval between the previous fractures and the onset of ulnar neuropathy was 19 years. The severity of nerve palsy was classified as McGowan's grade I in 24 patients, grade II in 8 patients, and grade III in 3 patients. The mean carrying angle was average 29 degrees in 33 cases with cubitus valgus and it was decreased to average 11 degrees postoperatively, but the angle was average -23 degrees preoperatively in 2 cases with cubitus varus and it was corrected to average 9 degrees postoperatively. the cause of palsy was analysed by mechanical stetching in 11 cases, compression by a fibrous band between the two heads of flexor carpi ulnaris in 8 cases, and diffuse fibrous adhesion around the ulnar tunnel in 5 cases. All patients was treated with supracondylar closing wedge osteotomy accompanied with anterior ulnar nerve transposition in 13 patients, corrective osteotomy only in 12 patients, and anterior ulnar nerve transposition only in 10 patients. Their end results were analysed as good in 24 cases, fair in 8 cases, and poor in 3 cases within average 6 months after the operations (4 to 13 months). The poor results was obtained in 3 cases out of 9 cases with corrective osteotomy group (33.3%). Conclusively, a tardy ulnar nerve palsy caused by post-traumatic elbow deformities should be corredcted with anterior ulnar nerve transposition with or without corrective closing wedge osteotomy but not by corrective osteotomy only, because of compressive neuropathy by diffuse fibrous adhesion or bands of two heads of FCU around the ulnar tunnel in elbow.

Treatment of Fractures of Lateral Condyle of Humerus with Compliations: Moon Sang Chung, Sung Churl Lee; J Korean Soc Fract 1995;8(3):659-666. Published online July 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.3.659

Fractures of the lateral condyle of the humerus are notorious for complications, most commonly nonunion with subsequent proximal migration of the ununited fragment, an increase in the carrying angle, and the tardy ulnar nerve palsy. In the past, the reconstructive surgery for complicated old fractures of the lateral condyle of the humerus had been hardly considered, but recently, attempts have been made to reconstruct the anatomy and function of the elbow joint. The authors have reviewed 21 cases of old fractures of the lateral condyle of the humerus, which had been treated at Seoul National University Hospital from April,1982 until March, 1990. For established nonunions of the lateral condyle fragment, better results were obtained from the procedure that includes osteosynthesis of the lateral condyle, attempting to restore the normal anatomy of the elbow joint. For tardy ulnar nerve palsies, better results were obtained from the procedure that includes medial epicondylectorny. Fractures of the lateral humeral condyle have many late problems in spite of treatment at the time of injury so early aggressive treatment is necessary. Even in cases with late problems, aggressive treatment should be done, too, as soon as possible.
