Introduction: The standard treatment of adolescent Blount’s disease includes proximal tibial valgus osteotomy and osteotomy of the fibula. Some believe that the fibula should also be fixed to prevent migration and subluxation. We performed correction of deformities in eight patients (10 tibiae) with adolescent Blount’s disease using the Taylor Spatial Frame (TSF). In all patients, the origin (virtual hinge) was placed at the level of the proximal tibial fibular joint. The purpose of this study was to review treatment outcome of proximal tibial osteotomy without osteotomy of the fibula in patients with adolescent Blount disease.

Methods: Eight patients (10 tibiae) were treated by proximal tibial osteotomies and gradual correction by TSF without fibular osteotomy over a period of three years. All patients were males with a mean age of 14.6 years (range, 14–17 years). All patients had severe proximal tibial varus, four had significant proximal tibial procurvatum, and six had internal tibial torsion. The fibula was not fixed in five patients, and fixed distally in three.

Results: Frames were removed at an average of 12.8 weeks (range, 12–15 weeks). The mean preoperative proximal tibial varus was 16.2o (range, 12–19o), corrected to normal values in all patients. The mean preoperative MPTA was 71.4o (range, 67–77o) and corrected to a mean MPTA 87.1o (range, 85–89o). In four patients (5 tibiae) with proximal tibial procurvatum, the PPTA was corrected to normal range.

Mean correction of internal tibial torsion was 10o (range, 5–15o), performed in six patients (8 tibias). Pre-operative MAD was 55.8 mm medial to center of the knee (range, 44–77 mm), corrected to a mean MAD of 4.9 mm medial to center of the knee (range, 2–11 mm).

Complications included superficial pin tract infections in seven patients.

No complications related to the fibula were observed during/after correction.

Conclusion: Based on our initial experience, we believe that most patients with adolescent Blount disease could have successful and predictable correction of tibial deformities without a need for osteotomy and fixation of the fibula.

Introduction: The standard treatment of displaced supracondylar fractures of the distal humerus in children is closed reduction and pin fixation, but the optimal pin configuration is controversial. Crossed-pin fixation of the humerus is mechanically more stable than any other kind of pin configuration, but this fixation may cause iatrogenic ulnar nerve injury. Many authors recommended fixation from the lateral side in order to eliminate this complication. Since 1999, we have been using a 3-pinfixation technique with insertion of the first two pins with the elbow in full flexion, followed by insertion of the third wire through the medial side with the elbow in full extension. We call this the “flexion-extension cross-pinning technique”.

Method: This is a retrospective review of 64 displaced supracondylar fractures fixed by flexion-extension cross pinning.

Results: Eleven children had Gartland type 2 fractures and 53 children had Gartland type 3 fractures. There was no iatrogenic ulnar neve palsy. Loss of reduction in two children was related to technical errors. One patient had superficial pin tract infection.

Conclusion: We feel that this technique and pins configuration is safe and easy to learn. It has become the standard method of fixation of displaced supracondylar fractures in our institution.
