Summary
Dislocation arthropathy after the Latarjet procedure is a long-term concern, affecting 36% of patients. Risk factors include age over 40 and lateral coracoid transfer, while hyperlaxity may be protective.
Area of Science:
- Orthopedic Surgery
- Shoulder Instability
- Arthroplasty
Background:
- The Latarjet procedure is a common surgical treatment for anterior glenohumeral instability.
- Long-term complications, such as dislocation arthropathy, require thorough investigation.
Purpose of the Study:
- To analyze the long-term incidence of dislocation arthropathy following a modified Latarjet procedure.
- To identify patient and surgical factors associated with the development of dislocation arthropathy.
Main Methods:
- A consecutive series of patients undergoing a modified Latarjet procedure between 1986 and 1999 were followed long-term.
- Multivariable regression analysis was used to assess risk factors for dislocation arthropathy.
Main Results:
- Dislocation arthropathy was observed in 36% of 117 patients after a mean follow-up of 16.2 years.
- Risk factors included surgery in patients over 40 years old (adjusted RR 2.2) and lateral coracoid transfer (adjusted RR 2.3).
- Hyperlaxity demonstrated a protective effect, with lower rates of dislocation arthropathy (adjusted RR 0.4).
Conclusions:
- Dislocation arthropathy is a significant long-term complication of the Latarjet procedure.
- Age over 40 and lateral coracoid transfer are identified as risk factors.
- Hyperlaxity appears to reduce the risk of developing dislocation arthropathy.
