Mirror hand-ulnar dimelia: a single centre experience with 13 patients

Area of Science:

• Congenital Disorders
• Orthopedic Surgery
• Pediatric Medicine

Background:

• Mirror hand-ulnar dimelia (MHUD) is a rare congenital disorder with varied presentations.
• Current classifications lack treatment guidance.
• Understanding MHUD's full limb involvement is crucial.

Purpose of the Study:

• To review clinical and radiological features of MHUD in 13 pediatric patients.
• To investigate predictors of functional outcomes in MHUD.
• To propose a comprehensive management algorithm for MHUD.

Main Methods:

• Retrospective review of 13 children with MHUD treated at a single institution.
• Analysis of clinical and radiographic data.
• Development of a management algorithm based on findings.

Main Results:

• MHUD typically involves the entire upper limb.
• Specific predictors of function were identified for each limb segment.
• A novel management algorithm was developed.

Conclusions:

• MHUD is a complex disorder affecting the entire upper limb.
• Treatment strategies should be tailored to functional predictors.
• The proposed algorithm offers a structured approach to MHUD management.
