Acromioclavicular joint separation treated with clavicular hook plate: a study of radiological and functional outcomes.
ACJ separation is a common shoulder injury. A variety of surgical techniques for high-grade ACJ separations have been described. A commonly used technique represents open reduction and fixation by a hook plate. Goal of the present study was to evaluate radiographic and functional outcome in patients with high-grade ACJ separations following surgical treatment with a hook plate before and after surgery as well as after hook plate removal. ⋯ In contrast to a significant higher CCD after hook plate removal, nearly all patients achieved good to excellent functional results for DASH and CMS. This indicates that loss of reduction does not necessarily lead to poor functional outcome after ACJ separation surgery.

In the setting of intra-articular distal radius fractures, the volar lunate facet (VLF) is the only articular segment that resists volar carpal subluxation. So, it is important to achieve a stable fixation of this key fragment. The VLF, when small (also called as volar marginal fragment, VMF) is located distal to the watershed line making fixation with the conventional volar locking plates difficult or impossible. ⋯ It is important to identify VMFs in intra-articular distal radius fractures. Anatomically designed volar hook plate achieves excellent low-profile stable fixation of this key fragment to allow early mobilisation without fearing loss of reduction and volar carpal subluxation.

Complications after surgical treatment of distal clavicle fractures.
Distal clavicle fractures have low rates of union when treated with conservative measures. Operative treatment is generally recommended for Neer type II and V. Multiple fixation methods exist with no clear gold standard. The goal of the current study is to assess the outcomes and complications of distal clavicle fractures treated with one of three fixation methods: standard clavicular plate, hook plate or suture fixation about the coracoid. ⋯ This study compared the outcomes of three different fixation methods for unstable distal clavicle fractures. The overall union rate with any method of operative intervention was very high (98.6%), consistent with previous studies. Hook plates had a much higher re-operation rate, mostly owing to a higher incidence of hardware removal, an expected outcome owing to the prominence of these plates in the subacromial space. Contoured clavicular plates were associated with a lower incidence of irritation and hardware removal than hook plates, although one patient in this group experienced loss of fracture fixation and went on to asymptomatic radiographic non-union. Suture-only fixation methods had the lowest rate of re-operation, with only one of 21 procedures resulting in failure and requiring revision. However, there was a significantly higher rate of adhesive capsulitis in the suture fixation cohort, perhaps due to the tethering effect of the clavicle to the coracoid or violation of the rotator interval. While this study supports that most distal clavicle fracture fixation methods can achieve stable union, there is a highly variable complication profile associated with each fixation method. The routine use of hook plate fixation cannot be recommended.

The management of distal clavicle nonunion represents a challenging task for orthopaedic trauma surgeon. Both the choice of the implant and whether a bone graft is needed are controversial points which must be addressed. ⋯ She was initially treated with a hook plate without bone grafting. After an early peri-implant fracture she was treated again with anatomical S-shaped locking plate associated with autologous cancellous bone graft.
