Radiological and Functional Outcomes of Joshi External Stabilization System (JESS) in Proximal Humerus Fractures: A Retrospective Review.

INTRODUCTION

There has been an increased interest in the external and percutaneous fixation of proximal humerus fractures. Numerous advantages of external fixation like less blood loss, ease of application, and rigid fixation provide a promising new avenue for the management of humeral fractures. This retrospective case series aims to assess the radiological and functional outcome of proximal humerus fractures treated with the Joshi External Stabilization system (JESS).

MATERIALS AND METHODS

A retrospective review of records was performed using hospital records from January 2020 to January 2024. The records of patients more than 18 years of age with proximal humerus fractures who were operated with the JESS fixator were reviewed and a proforma based on each follow-up was filled by the investigators.

RESULTS

A total of 28 patients met the inclusion criteria with an average age of 65.17 ± 13.1 years. Neers type 3 injuries were most common (38.3%,  = 11). All fractures united on 6-week follow-up. 75% ( = 21) reported good 25% ( = 7) excellent Constant scores at 24 weeks. The overall complication rate was 28.6%. Common complications were superficial pin tract infections and fixator loosening.

CONCLUSION

The JESS is an acceptable treatment option for orthopaedic surgeons for the fixation of proximal humeral fractures, especially in geriatric patients. Like other external fixation devices, pin tract infection and pin loosening are inherent to the system.
