Insights
Shoulder deformities are common after birth palsy. This paper reviews existing classifications and proposes a new system for secondary shoulder deformities in pediatric patients.
Area of Science:
- Orthopedics
- Pediatric Surgery
- Neurology
Background:
- Shoulder deformities are a frequent complication following birth palsy.
- Existing classification systems for these deformities have limitations.
Purpose of the Study:
- To review current classification systems for secondary shoulder deformities resulting from birth palsy.
- To introduce a novel classification system for these deformities.
Main Methods:
- Literature review of previous classification systems.
- Development and presentation of a new classification framework.
Main Results:
- Analysis of the strengths and weaknesses of existing classification systems.
- Introduction of a new, comprehensive classification for secondary shoulder deformities.
Conclusions:
- A need exists for a refined classification system for shoulder deformities in birth palsy.
- The proposed classification aims to improve diagnosis and treatment planning.
Abstract:
Shoulder deformities are the most frequent sequelae of birth palsy. In this paper, previous classification systems for secondary shoulder deformities are reviewed and a new classification is offered.

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.
