Summary
Locked plate fixation for complex proximal humerus fractures offers superior functional outcomes and patient satisfaction compared to hemiarthroplasty. This surgical approach demonstrates better range of motion and overall shoulder scores in patients with 3- and 4-part fractures.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Biomechanics
Background:
- Surgical management of 3- and 4-part proximal humerus fractures presents significant challenges.
- Evaluating functional outcomes is crucial for determining optimal treatment strategies.
Purpose of the Study:
- To compare the functional outcomes of locked plate fixation versus hemiarthroplasty in patients with 3- and 4-part proximal humerus fractures.
- To assess patient satisfaction and pain levels between the two surgical groups.
Main Methods:
- Retrospective evaluation of 57 patients with 3- and 4-part proximal humerus fractures treated between 2003 and 2005.
- Comparison of functional outcomes using the American Shoulder and Elbow Surgeons score, Simple Shoulder Test, Euroqol EQ-5D, visual analog pain scale, Constant Score, and UCLA Shoulder score.
- Analysis of range of motion and patient satisfaction.
Main Results:
- The open reduction and internal fixation (ORIF) group showed significantly better American Shoulder and Elbow Surgeons scores, Simple Shoulder Test results, patient satisfaction, Constant Scores, and UCLA Shoulder scores compared to the hemiarthroplasty group.
- ORIF also demonstrated significantly improved forward flexion and abduction range of motion.
- No significant differences were observed in SF-12, Euroqol EQ-5D, or visual analog pain scale scores, though ORIF trended favorably.
Conclusions:
- Locked plate fixation is associated with superior functional outcomes, including range of motion and patient-reported scores, for 3- and 4-part proximal humerus fractures compared to hemiarthroplasty.
- While pain and general health scores showed no significant difference, the functional advantages favor ORIF.
- Further research may explore long-term outcomes and cost-effectiveness.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
