Insights
Biceps-to-triceps transfer improved shoulder abduction in children with brachial plexus birth palsy. The surgery enhanced shoulder movement without negatively impacting elbow flexion, aiding functional recovery.
Area of Science:
- Pediatric Orthopedics
- Pediatric Surgery
- Reconstructive Surgery
Background:
- Brachial plexus birth palsy can lead to functional deficits.
- Concurrent shoulder abduction and elbow extension impairments are common after natural recovery.
- Muscle cocontraction can limit active movement.
Purpose of the Study:
- To evaluate the efficacy of biceps-to-triceps transfer.
- To address shoulder abduction and elbow extension deficits.
- To improve functional outcomes in children with specific palsy-related impairments.
Main Methods:
- Surgical intervention: biceps-to-triceps transfer.
- Patient cohort: three children with specific functional deficits.
- Assessment: evaluation of active shoulder abduction and elbow flexion.
Main Results:
- Significant improvements in active shoulder abduction were achieved.
- Elbow flexion strength and active range of motion were preserved.
- Functional gains were observed in shoulder function.
Conclusions:
- Biceps-to-triceps transfer is a viable surgical option.
- The procedure effectively restores shoulder abduction.
- It addresses functional deficits without compromising elbow function.
Abstract:
Biceps-to-triceps transfer was performed in three children with concurrent deficits in shoulder abduction and elbow extension attributable to cocontraction following natural recovery from brachial plexus birth palsy. Substantial improvements in active shoulder abduction were observed without impairing elbow flexion.

01:31Muscles that Move the Arm
5.6K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:16Muscles that Move the Forearm
4.6K
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...

01:22Spinal Nerves: Plexus I
3.6K
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.

01:23Muscles of the Shoulder
10.8K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:12Arteries of the Upper Limbs
3.1K
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...

01:24Muscle Coordination and Action
3.7K
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
