Background: This study was to retrospectively compare and review the clinical outcomes between the distal clavicular locking plate and clavicular hook plates in the treatment of unstable distal clavicle fractures using Constant Murley score. Materials and methods: The main outcome comparisons included Constant score, rate of non-union, rate of complication, and rate of returning to work three months postoperatively. This study include total of 30 cases with displaced lateral end clavicle fractures satisfying the inclusion criteria treated with lateral clavicle locking plate (15cases) and clavicle hook plate (15 cases). Patients were followed up at 1st month, 2nd month and 6th month, the functional outcome was assessed using Constant Murley score and the radiological outcome was also assessed. Results: In our study, 15 cases treated with clavicle hook plate had better results than 15 cases treated by lateral clavicle locking plate in terms of fracture union, Constant Murley score, range of movements. At the final follow-up of 6 months, excellent outcome was seen in 26.7% of patients treated with hook plate as compared to 6.7% of patients treated with lateral clavicle locking plate. Conclusion: However, internal fixation with a distal clavicular locking plate had greater ability to return to their previous work after surgery in three months and fewer complications than the clavicular hook plate. Both hook plate and locking plate have a good functional outcome for lateral end clavicle fractures. Addressing the coracoclavicular ligaments in case of lateral locking plate is of utmost importance in comminuted lateral end clavicle fractures. Hook plate is an absolute indication for comminuted lateral end clavicle fractures. Hook plate has implant-related complications, hence implant removal at earliest is advisable.
