Introduction: Phalangeal fractures either closed or open, are common injuries of the hand. These injuries are encountered every day. These fractures can be treated conservatively or operatively depending on the nature of injuries, fracture pattern, and fracture stability. Various methods are used for this purpose including internal fixation by ‘K’ wires and external fixation by JESS technique. Objective: To find out the Evaluation of External fixation of Unstable Phalanges fractures of hand by JESS (Joshis External Stabilization System) fixation technique. Material and Methods: This study was conducted by the Department of orthopedics at Kushtia Medical College Hospital, Kushtia Bangladesh during the period of two years (January 2018- December 2019). A total of 60 cases of compound and or unstable fractures of metacarpal and phalangeal were included into the study. The stable fractures and hand injuries without fractures were excluded from the study. On the arrival at the hospital, primary resuscitative measures were taken such as recording of vital parameters and rapid systemic evaluation. The wounds were cleaned with dilute hydrogen peroxide, normal saline and Betadine and covered with sterile dressings. Suitable splints were placed onto the hand. Detailed radiological study was carried out and systemic, clinical examination was made and charted. The patients were divided into two groups, Group I who were treated with internal fixation and Group 2 were treated with JESS fixation. Results: Out of the total 60 cases, internal fixation was done in about 44 cases and JESS being performed on 26 patients. Transverse and comminuted were the most common type of fractures, together accounting for about 50% of the cases. The outcome of the treatment was excellent in 50% of the cases among those who were treated with JESS, while less than 40% had excellent outcomes and many had poor outcomes among the patients treated by internal fixation. Conclusion: In the compound fractures, the use of JESS method would be more useful in the repair of hand fractures.
