Treatment of Chronic Isolated Radial Head Dislocation in Children

RETRACTED ARTICLE: Missed Monteggia fracture in children: Is annular ligament reconstruction always required?

“…Some authors have reported that an open reduction of the radial head is sufficient and an ulnar osteotomy is not required [25,26]. Others have reiterated that ulna osteotomy is almost always necessary to restore radial head alignment [23,26,27].…”

Open reduction, ulnar osteotomy and external fixation for chronic anterior dislocation of the head of the radius

“…2 Continuous ulnar lengthening as the primary step with an attempt at closed and if necessary open reduction at the end of lengthening has also been proposed. 27 We found that reconstruction of the annular ligament was not necessary since 16,[21][22][23]25 in all our patients the heads were stable without such reconstruction. When the radial head is deformed, stability cannot be fully restored by reconstruction of the ligament.…”

“…In some cases such a deformity may never have been present. 1,[23][24][25][26] We could only detect minor deformities of 5˚ to 10˚ of ulnar extension in the lateral radiographs of four of 12 patients with a history of injury. Other authors have reported anterior bowing of the ulna in 75% to 100% of post-traumatic dislocations.…”

“…Pronation and supination are the most likely to deteriorate. 15,23 Ligamentous reconstruction seems to have a negative effect on pronation with reported deterioration in 20% to 100% of patients, 2,3,7,10,15,28 even with the use of functional postoperative exercises. 2 Angular ulnar osteotomy and open joint reconstruction can lead to stable reduction of the radial head with minimal complications.…”

Open Reduction and 3-Dimensional Ulnar Osteotomy for Chronic Radial Head Dislocation Using a Computer-Generated Template: Case Report

“…of this deformity 3,21,22 varies from 33% to 100%, and some authors have reported that such a deformity might have never been present. 23,24 A varus deformity was found to be common in some cases, 25 but no coronal deformity was found in other cases. 22 Rotational deformity is difficult to assess by clinical and plain x-ray methods alone.…”
