Clinical Presentation
Patients had a mean preoperative Constant score of 31 points, reflecting significant functional impairment prior to surgery [PMID:19181978].
Management
CHHR preserves bone structure, making it particularly suitable for younger patients with intact glenoid cartilage [PMID:40820162].
In a study involving 17 patients treated with cementless humeral replacement arthroplasty, the mean Constant score improved significantly from 31 to 62 points (p < 0.0001) [PMID:19181978].
Complications
The paper highlights the importance of timely intervention in advanced stages to avoid complications, though specific complication rates from CHHR in juvenile patients are not provided [PMID:40820162].
Prognosis & Follow-up
The study reports good to excellent long-term results with high patient satisfaction following CHHR, though specific juvenile patient data is limited [PMID:40820162].
The study reported significant improvements in shoulder flexion, abduction, and external rotation, with mean follow-up of three years [PMID:19181978].
