Summary
This study introduces a new upper limb kinematics analysis protocol for assessing obstetrical brachial plexus palsy (OBPP). The protocol effectively quantizes surgical outcomes, showing significant improvements in shoulder and elbow movements post-operation.
Area of Science:
- Biomechanics
- Clinical assessment
- Pediatric orthopedics
Background:
- Upper extremity kinematics analysis is gaining traction in clinical practice.
- A novel protocol was developed for normative data in healthy children and OBPP patients.
- Obstetrical brachial plexus palsy (OBPP) affects upper limb function in newborns.
Observation:
- The protocol utilizes reflective markers and optoelectronic cameras for 3D motion capture.
- Coefficient of Multiple Correlation (CMC) quantifies kinematic curve similarity.
- A kinematics corridor was established for healthy children's upper limb movements.
Findings:
- Kinematics analysis identified subtle movement anomalies in an OBPP patient missed by clinical exams.
- Post-surgical CMC scores improved from 'poor' to 'excellent' for shoulder movements.
- Range of motion increased by 28-67% post-surgery, demonstrating significant functional gains.
Implications:
- This protocol offers a valuable tool for pre-operative evaluation and post-operative assessment in OBPP.
- Quantifiable movement gains can guide surgical treatment and rehabilitation strategies.
- Further studies with larger patient cohorts are needed to validate these promising results.

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

01:16Muscles that Move the Forearm
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

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...
