Background:
Surgical reconstruction of acromioclavicular joint (ACJ) disloca-
tions has been performed in our department using the modified Weaver Dunn
procedure with either a PDS band or an anatomical designed Baltzer ACJ-hook
plate as temporary reinforcement
Purpose / Aim of Study:
Aim of this study was to assess clinical outcome of
reconstructions of ACJ dislocation using our two traditional techniques.
Materials and Methods:
From 01.01.2014 until 01.07.2016 forty patients
were operated for ACJ reconstruction due to an clinically unstable ACJ with
modified Weaver Dunn technique with either a PDS band or a Baltzer ACJ hook
plate as a temporary reinforcement. Clinical evaluation was done with the Ox-
ford Shoulder scoring system. 34 patients returned the questionnaire (20 pa-
tients operated with a modified Weaver Dunn with PDS band and 14 patients
operated with a with a Baltzer plate). A separate subjective evaluation of the
cosmesis of the operation was included in the evaluation. The Baltzer ACJ-hook
plate was removed surgically after 6-8 weeks in GA, whereas the PDS band is
reabsorbabel and no secondary operation is needed.
Findings / Results:
The mean Oxford Score was 37.4 ( 37,3 for the PDS group
and 37,6 for Baltzer plate group). Median was 44 (36-47) , p = 0.91. There
was no statistically significant differences in any of the clinical outcomes be-
tween the two different techniques. 25 patients had good results (score 30-
48) and 9 patients had moderate to unsatisfied results. The result of cosmetic
satisfaction was in favour of the PDS band.
Conclusions:
Our results is similar to other studies with reconstruction of the
chronic unstable ACJ with failure rates between 15-25 %. The modified Weaver
Dunn procedure offers an acceptable solution to an unstable ACJ in symptom-
atic patients using either a temporary reinforcement with the PDS band or the
Baltzer plate.
