Summary
Rockwood type VI acromioclavicular dislocations are rare, with most patients treated surgically and achieving good functional outcomes. Awareness is key to prevent missed diagnoses.
Area of Science:
- Orthopedic Surgery
- Trauma Management
- Sports Medicine
Background:
- Rockwood (RW) type VI acromioclavicular (AC) dislocations are rare, high-energy injuries.
- Limited data exists on optimal management and long-term outcomes for these injuries.
Purpose of the Study:
- To systematically review literature on RW type VI AC dislocations.
- To analyze patient demographics, injury mechanisms, treatments, and outcomes.
Main Methods:
- Comprehensive literature search conducted February 5, 2025.
- Included case reports and case series of RW type VI AC dislocations.
- Qualitative synthesis performed due to data heterogeneity.
Main Results:
- 24 patients identified (10 VIa, 14 VIb), mostly from motor vehicle accidents.
- 91.7% treated surgically; 2 cases had spontaneous reduction.
- 21/24 patients achieved full range of motion and pain-free function with satisfactory radiographic results.
Conclusions:
- RW type VI AC dislocations are rare, with subclassification potentially aiding management.
- Surgical management is common, but no single approach is superior.
- Outcomes are generally favorable with low complication rates; further research is needed.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:16Structural Joints: Synovial Joints
6.3K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
