Restarting Stalled Replication Forks

Restarting Stalled Replication Forks

DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart, a...

Summary

Revision surgery for failed acromioclavicular (AC) joint reconstruction can be challenging. A doubled semitendinosus autograft offers a viable solution for complex AC joint instability, achieving excellent patient outcomes.

Area of Science:

Orthopedic Surgery
Sports Medicine
Reconstructive Surgery

Background:

Surgical stabilization of the acromioclavicular (AC) joint has a failure rate of up to 10%.
Revision AC joint reconstruction presents significant challenges due to altered anatomy and compromised stabilizing structures.
Existing revision techniques, including modified Weaver-Dunn procedures, may not always be successful.

Observation:

This report details a case of multiple failed AC joint reconstructions.
A doubled semitendinosus autograft was utilized for revision surgery.
Biomechanical studies support the use of autograft or allograft tendons for AC joint stabilization.

Findings:

The surgical technique involved harvesting a semitendinosus graft, passing it through clavicular and coracoid tunnels, and securing it with a Fiber-Wire cerclage.
The graft was doubled around the medial clavicle and coracoid hook, then sutured to itself.
Post-operative immobilization in a sling was employed.
At 12 months, the patient reported no pain, with a Constant Score of 87/100 and a Neer Score of 94/100.

Implications:

This case demonstrates the potential efficacy of a doubled semitendinosus autograft in managing complex, failed AC joint reconstructions.
The technique provides a reconstructive option for patients with significant instability and altered anatomy.
Successful outcomes suggest this approach may restore function and alleviate pain in challenging revision cases.
