Results of Hook Plate Fixation of Unstable Distal Clavicle Fractures: Hoon Sang Sohn, Byung Chul Jo; J Korean Fract Soc 2011;24(4):335-340. Published online October 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.4.335

Abstract PDF: PURPOSE
This study evaluated the clinical and radiological outcomes of unstable distal clavicular fractures treated with an AO Hook plate.
MATERIALS AND METHODS
From March 2009 to October 2010, sixteen patients with distal clavicular fractures underwent open plating using an AO Hook plate. The clinical outcomes were assessed by measuring the UCLA scores and KSS sores, and the radiological outcomes were evaluated using simple radiographs at the final follow-up.
RESULTS
Fracture union was obtained in all patients at an average of 13.9 weeks (range, 9~20 weeks). The UCLA scoring system showed excellent results in 9 cases and good results in 7. The average KSS scores of distal clavicular fractures were 95.5. At the final follow-up, subacromial osteolysis developed in 11 cases (68.7%) of whom 3 suffered from pain around the acromion. Other complications occurred in 4 patients: one had a fracture adjacent to the plate proximally, two had a stiff shoulder with subacromial impingement, and one had hypoesthesia around the surgical wound.
CONCLUSION
Unstable distal clavicular fractures treated with a Hook plate provided rigid fixation and satisfactory outcomes considering the high union rate. Nevertheless, potential postoperative complications related to morphometric properties of the plate should be considered.

The Surgical Treatment of Distal Clavicle Fractures: Eun Sun Moon, Jong Wook Jung, Gwang Cheul Jeong; J Korean Soc Fract 2001;14(4):706-713. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.706

Abstract PDF: PURPOSE
To evaluate and analyze the clinical and radiological result of surgical treatment for distal clavicular fractures.
MATERIALS AND METHODS
From Jan. 1995 to May. 2000, eighteen cases of distal clavicle fractures were treated operatively. Among them, fifteen cases with more than 12 months follow-up were analyzed retrospectively. In Neer classification, type I was 1 case and 14 cases were type II. We performed closed reduction in 4 cases and open reduction in 11 cases. We treated with Steinman pin in I case, K-wires in 6 cases and coracoclavicular screw(Bosworth technique) in 6 cases. One case was treated with coracoclavicular screw due to screw loosening which was used in primary operation. Another case was treated by internal fixation with plate and K-wire due to delayed union after conservative treatment of segmental fracture. Mean follow up period was 18 months(12~62 months). Clinical results was evaluated by Kona s criteria.
RESULTS
Radiological evidence of solid union was detected within 10 weeks in 13 cases. Clinical results were satisfactory in 13 cases (excellent in 10 cases and good in 3 cases). In K-wire fixation, all six cases were demonstrated excellent result. In coracoclavicular screw fixation, four of six cases were excellent, one was good and one was fair. Poor result was noted in one case of Steinmann pin fixation due to nonunion and limitation of range of motion. SUMMARY: Surgical treatment of distal claviclular fracture would obtain satisfactory clinical result with early range of motion exercise and reduce the complications such as nonunion and sustained pain.
