- Cubitus valgus may arise as the sequele of a number of different condition for example, a premature epiphysiodesis of the lateral condylar physis, nonunion or malunion of the lateral condylar fracture, rarely supracondylar fracture of the humerus. Cubitus valgus has more functional loss of extension and possibly the late development of a tardy ulnar nerve paralysis and less significant cosmetic effect. Authors treated the 7 patients who had cubitus valgus developing as a sequele of nonunion of the lateral condyle of the humerus, by the medial closed wedge osteotomy and internal fixation with the lateral arm cut anatomical Y-plate through posterior approach. Five males and two females were followed average 19 months(range 5 to 37 months). A mean age at the time of the operation was 17.1 years(range 13 to 25 years). Symptoms of tardy ulnar nerve palsy was shown in 5 patients. Two patients were treated due to disappearing cosmetic problem. The carrying angle was mean valgus 31 (range 22~50) preoperatively. The carrying angle was changed from mean valgus 9.6(range 3-15) immediate postoperatively to valgus 9(range 3-14) followed state. The duration of external immobilization after operation was mean 4.1 weeks(range 3-5 weeks). Range of motion of the elbow was fully recovered in 6 cases. The neurologic deficit of the tardy ulnar nerve palsy was fully recovered in all five patients. The result of supracondlar osteotomy was excellent in 4 cases(57.1%), good in 2 cases(28.6%) and poor in 1 case(14.3%). In conlusion, internal fixation with the lateral arm cut anatomical Y-plate after medial closed wedge osteotomy through the posterior approach can be recommanded as a method of treatment for the cubitus valgus.

Abstract

- Fractures of the distal radius represent the most common fractures of upper extremity and treatment remains challenging. Recently, more extensive therapeutic method is represented for reduction and maintenance of distal radius unstable fracture.
Twenty patients, 21 cases of distal radius fracture treated by external fixator between June, 1991 and September, 1995 were followed by more than one year to evaluate the correlation between anatomical and functional results. To assess the functional results, we used Green and OBriens system which scores subjective and objective findings. Grip power ratio was checked with Jamar dynanometer. To assess the anatomical results, volar tilt, radial inclination and radial length were measured. Frykmann type VIII and Universal type IV C fractures are most common form(7 cases, 33%) in our study. The more severe form of fracture of distal radius, the less score in funtional results. There was a little loss of velar tilt, radial inclination and radial length on last follow-up radiographs. In radiographic parameters, radial length showed significant correlation with ulnar deviation(p=0.002). In complication, sudek atrophy(2 cases), ulnar nerve entrapment symptom(1 case), and writing problem(1 case) was seen, but not serious. We concluded that external fixation in distal radius fracture is one of the treatment method expecting good result without serious complication.
