Purpose
The purpose of this study was to evaluate the functional outcomes and complications of endoprosthesis-PPP mesh composite reconstruction after bone tumour resection of the proximal humerus.
Methods
We retrospectively analysed 18 patients treated in our department with endoprosthesis-PPP mesh composite reconstruction after bone tumour resection of the proximal humerus between March 2005 and October 2010. Sixteen patients (16/18) were followed up for 56 months (range, 30–96 months). The pre- and post-operative pain severity was assessed according to a 10-cm visual analogue scale (VAS). The clinical results of functional improvement were assessed by Musculoskeletal Tumour Society (MSTS) score at the time of final follow-up. Moreover, we also analysed complications associated with the reconstruction procedure.
Results
Most patients experienced some alleviation of pain two weeks after the reconstruction surgery. The mean MSTS upper extremity functional outcome score at the time of final follow-up was 20 (66.7 %, range, 16–27). Mean shoulder abduction was 36° (range, 18–125°) and mean shoulder flexion was 39° (range, 21–120°). Local recurrence occurred in only one patient (6.25 %), aseptic prosthesis loosening occurred in one patient (6.25 %) and anterior subluxation occurred in one patient (6.25 %).
Conclusions
The capsule reconstruction on the basis of PPP mesh can significantly reduce the recurrence rate of glenohumeral joint instability, which may offer an alternative for the capsule reconstruction after bone tumour resection of the proximal humerus.
