Insights
Obstetrical brachial plexus palsy (OBPP) is infant arm paralysis caused by delivery trauma. Treatment evolved from surgery to conservative care, then back to surgery with improved techniques.
Area of Science:
- Obstetrics and Gynecology
- Pediatric Neurology
- Surgical Innovation
Background:
- Historically, infant arm paralysis was noted, with obstetric causes considered from the mid-1700s.
- The term obstetrical brachial plexus palsy (OBPP) emerged in 1872, linking excessive traction during delivery to arm paralysis.
Observation:
- Early surgical interventions (19th century to 1930) yielded poor outcomes.
- A subsequent 40-year period favored conservative management due to poor surgical results and spontaneous resolutions.
Findings:
- Advances in microsurgery by the late 1960s reignited interest in surgical approaches for OBPP.
- Current management involves evaluating risk factors, clinical presentation, and treatment options.
Implications:
- Understanding OBPP management and outcomes is crucial for developing effective parental support strategies.
- This review provides insights into the historical evolution and current state of OBPP treatment.
Abstract:
Since the days of Hippocrates, scripts have included descriptions of infants who were unable to move their arms. However, it was not until the mid-1700s that an obstetric cause for the paralysis was considered. In 1872, the term obstetrical brachial plexus palsy was coined when a correlation was made between excessive traction on the brachial plexus during delivery and the clinical finding of arm paralysis. Surgical intervention became the norm in the beginning of the 19th century and continued until 1930. Poor outcomes and spontaneous resolution of obstetrical brachial plexus palsy prompted a 40-year span of conservative treatment. By the late 1960s, advances in technology and microsurgical techniques revived interest in surgical intervention in the management of obstetrical brachial plexus palsy. This article focuses on obstetrically caused brachial plexus injury, including risk factors, clinical presentation, and treatment options and outcomes. An understanding of current medical practices and their outcomes also provides a basis on which to develop sound support strategies to help parents who face this dilemma.
