Summary
Shoulder hemiarthroplasty provides good outcomes for posttraumatic and degenerative conditions. Early posttraumatic replacement yields better results, with patient satisfaction high and pain improving over time.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Rehabilitative Medicine
Background:
- Comparative analysis of mid-term outcomes for posttraumatic and degenerative shoulder hemiarthroplasty.
- Evaluation against existing literature data for shoulder joint replacement.
Purpose of the Study:
- To compare mid-term findings of posttraumatic versus degenerative shoulder hemiarthroplasty.
- To assess the impact of primary versus secondary implantation timing in posttraumatic cases.
Main Methods:
- Retrospective study of 26 patients (20 posttraumatic, 6 degenerative).
- Evaluation using Constant Score, subjective patient assessment, and radiographs.
- Follow-up period averaged 38-41 months.
Main Results:
- Posttraumatic group: Constant Score 65; Degenerative group: Constant Score 74.
- Primary posttraumatic implantation (68) superior to secondary (59).
- Significant pain improvement in posttraumatic group; 92% patient satisfaction.
Conclusions:
- Hemiarthroplasty is a suitable alternative for posttraumatic shoulder conditions, especially in older patients, with better outcomes if performed within four weeks.
- Good to excellent results expected for primary osteoarthritis and idiopathic humeral head necrosis.
- Patient compliance and rotator cuff integrity are key factors for successful outcomes in both groups.
