Summary
This study analyzed persistent paralysis patterns after traumatic brachial plexus injuries. Reconstructive surgeries like muscle transposition and arthrodesis were performed to improve upper extremity function in patients with significant muscle weakness.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Rehabilitation Medicine
Background:
- Traumatic brachial plexus lesions frequently result in persistent paralysis and significant upper extremity dysfunction.
- Understanding the patterns of muscle weakness is crucial for effective surgical planning and functional restoration.
Purpose of the Study:
- To evaluate persistent patterns of paralysis following traumatic brachial plexus injuries.
- To present consecutive reconstructive operations based on a differential therapy concept.
Main Methods:
- Prospective evaluation of muscle power in 104 patients with brachial plexus palsy between 04/1994 and 12/2000.
- Analysis of performed reconstructive surgeries between 04/1994 and 06/2002, including muscle transposition, arthrodesis, and osteotomy.
Main Results:
- High prevalence of insufficient muscle power (grades 0-2) was observed in key upper extremity muscles, including deltoid (90%), supraspinatus (82%), and infraspinatus (93%).
- Common reconstructive procedures included trapezius transfer (n=80), shoulder arthrodesis (n=26), and transposition of forearm flexors (n=19).
Conclusions:
- Persistent paralysis patterns after brachial plexus lesions necessitate tailored reconstructive strategies.
- Surgical interventions like muscle transposition, arthrodesis, and corrective osteotomy can improve upper extremity function by addressing individual neuromuscular defects and deformities.
