PURPOSE
To investigate the surgical outcomes of orthogonal locking compression plate fixation for distal humeral intraarticular fractures.
MATERIALS AND METHODS
This study included 18 patients presenting a distal humeral intraarticular fracture who were treated with orthogonal locking compression plate fixation. According to the AO/OTA classification, there were eight C2 and ten C3 fractures. We evaluated radiologic outcomes, clinical results with range of motion, operation-related complications, and functional score by Mayo elbow performance score (MEPS).
RESULTS
The a verage u nion t ime was 3.5 months, and there was no c ase of r eduction l oss of a rticular f racture at t he last follow-up. Additional surgical procedures were needed in the three cases of C3 fractures. There was one case of heterotrophic ossification and one case of K-wire irritation. The average range of motion of elbow joint was 7° to 122°, and functional results were graded as 14 excellent, three good, and one fair by MEPS.
CONCLUSION
Anatomical reduction and internal fixation with orthogonal locking compression plate could provide satisfactory surgical outcomes for the treatment of distal humeral intraarticular fracture.

Hypoesthesia after Open Reduction and Plate Fixation of Clavicular Midshaft Fractures: Correlation with Plate Location and Clinical Features of Hypoesthesia
Seong Hun Kim, Joon Yub Kim, Kyoung Hwan Koh, Myung Gon Jung, Jae Ho Cho
J Korean Fract Soc 2016;29(2):121-127.   Published online April 30, 2016
DOI: https://doi.org/10.12671/jkfs.2016.29.2.121
AbstractAbstract PDF
PURPOSE
The aim of this study is to evaluate the correlation between the location of the plate and the incidence of clavicular hypoesthesia and the clinical features of patients with clavicular hypoesthesia after open reduction and internal fixation of clavicular midshaft fractures.
MATERIALS AND METHODS
Seventy-eight patients who underwent open reduction and plate fixation for clavicle midshaft fractures between March 2013 and October 2014 were assessed for eligibility. The total clavicular length (A), the distance to the medial end of the plate from the sternoclavicular joint (B), and the distance to the lateral end of the plate from the sternoclavicular joint (C) were measured. Correlation between the location of the clavicular plate and the incidence of clavicular hypoesthesia was evaluated. In addition, the severity, and recovery of hypoesthesia were evaluated. Patient satisfaction, pain visual analogue scale were evaluated regarding hypoesthesia.
RESULTS
The incidence of hypoesthesia was 32.1% (25/78 patients). No correlation was observed with respect to the location of the clavicular plate and the incidence of clavicular hypoesthesia (p=0.666 at the medial end, p=0.369 at the lateral end). Recovery from hypoesthesia was observed in 23 out of 25 patients (p=0.008). Patient satisfaction and pain showed negative correlation with the incidence of hypoesthesia (p=0.002 and p=0.022).
CONCLUSION
There was no correlation between clavicular hypoesthesia and the plate location. Although most cases of hypoesthesia were recovered, we should try to avoid hypoesthesia due to the negative 'correlation' with patient satisfaction and pain.

Anatomical Reduction of All Fracture Fragments and Fixation Using Inter-Fragmentary Screw and Plate in Comminuted and Displaced Clavicle Mid-Shaft Fracture
Kyoung Hwan Koh, Min Soo Shon, Seung Won Lee, Jong Ho Kim, Jae Chul Yoo
J Korean Fract Soc 2012;25(4):300-304.   Published online October 31, 2012
DOI: https://doi.org/10.12671/jkfs.2012.25.4.300
AbstractAbstract PDF
PURPOSE
To report the treatment results of anatomical reduction of all fracture fragments and internal fixation using an inter-fragmentary screw and plate in displaced mid-shaft clavicle fracture with comminution.
MATERIALS AND METHODS
Between June 2005 and August 2011, 13 consecutive displaced clavicle fractures with comminution (Edinburgh classification IIB2) treated by anatomic reduction and internal fixation using inter-fragmentary screw and plate were retrospectively evaluated. There were 11 male and 2 female patients with a mean age of 37.4 years (15~55 years). The right clavicle was injured in 4 patients and the dominant arm was involved in 46%. The mean duration from trauma to surgery was 7.0 days. The cause of injury was a traffic accident in three, a fall in two, and sports activity or direct injury in eight patients. All of the fracture pieces were anatomically reduced and fixed with inter-fragmentary screws. An additional plate was applied to maintain and reinforce the reduction of the fracture. Radiographic assessments for the numbers of fragments and the amount of shortening and displacement were performed. To verify the fracture healing and determine the time from fracture surgery to union and complications, all of the radiographs taken after surgery were evaluated.
RESULTS
The number of fragments was 2 in 7 cases, 3 in 5 cases, and 6 in one case. The mean shortening of the clavicle was 1.1 cm (0.3~2.1 cm) and mean displacement between the main fragments was 2.6 cm (1.3~4.5 cm). The mean duration of follow-up was 16.5 months (8~26 months). Radiographic union was achieved in all patients with a mean time to union of 10.8 weeks (8~14 weeks). There were no complications including metal failure, nonunion, or infection.
CONCLUSION
Anatomical reduction of all the fracture fragments and fixation using inter-fragmentary screws in addition to the usual plate fixation showed good fracture healing in displaced clavicle fracture with comminution.
