Osteolysis of the Distal Clavicle: Serial Improvement and Normalization of Acromioclavicular Joint Space with Conservative Care
Received 2 December 2002; received in revised form 2 January 2003
Objective
To  discuss a case of osteolysis of the distal clavicle (ODC) in a  29-year-old male chiropractic student who showed interval radiographic  and clinical evidence of healing.
Clinical Features
The  patient complained of intermittent left-sided shoulder pain of 8 months'  duration that was exacerbated while performing spinal-manipulative  procedures. A radiographic examination showed changes consistent with  osteolysis involving the distal clavicle.
Intervention and Outcome
A  conservative treatment regimen of physiotherapy, nutritional  supplementation, and activity modification resulted in an interval  reduction in symptomatology and radiographic findings on serial  examinations, ultimately resolving both abnormal clinical and  radiographic findings after approximately 14 months of treatment. We  specifically observed normalization of the acromioclavicular (AC) joint  dimension.
Conclusions
In contrast to the posttreatment  radiographic outcome seen in our patient, ODC classically does not  result in complete resolution of radiographic findings or normalization  of AC joint dimension, and such radiographic normalization of joint  space is currently not reported in the literature. This case report  serves to document and to show this unique occurrence.
