  Purpose

The investigators propose to test the hypotheses that compared with Hook Plate (HP), Locking Plate (LP) reduces the postoperative complications and leads to a better functional recovery after unstable distal clavicle fractures (Neer 2b).

Primary Outcome Measures:
  • the postoperative complications [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    complication that related with surgery or fracture will be defined as any event that necessitated another operative procedure or additional medical treatment


Secondary Outcome Measures:
  • the affected limb function [ Time Frame: 3, 6, 9,12 months ] [ Designated as safety issue: No ]
    the affected limb function measured using the Constant-Murley Score and using the Disabilities of the Arm, Shoulder and Hand (DASH) Score measured at 3, 6,9and 12months post-operatively.


Estimated Enrollment: 40
Study Start Date: May 2012
Estimated Study Completion Date: May 2014
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Hook Plate
20 participants will be enrolled in this group.
 Device: Hook Plate
All participants will have an open reduction internal fixation. The affected upper limb will be temporarily fixed by a sling after admission. Under necessary test, general anaesthetic and antibiotic prophylaxis, the patients will be placed in a beach-chair position in an orthopaedic theatre. The operated side will be prepped and draped and a transverse incision will be made over the fracture site. The fracture ends will be identified, reduced and fixed with HP. X-ray was applied to check the grade of reduction before the operation is completed. Post-operative care will include early active mobilization managed by a standard physiotherapy rehabilitation regime.

Detailed Description:

Controversy exists regarding the optimal treatment for patients with unstable distal clavicular fractures (Neer 2b). The recognized treatment alternatives are Hook plate.Notably, criticisms on this fixation method also appeared and the potential risks of hook migration, loosening, subacromial impingement or rotator cuff injury, and acromial osteolysis were still unsolved. Recently, Herrmann et al.and Largo et al.stabilized the distal clavicle with Locking plate (LP) and these studies offered encouraging support for LP. Because of small sample size (27 patients) and nonrandomization, the convictive power of these researches is not strong enough.
