Usefulness of Reduction and Internal Fixation Using a 2.4 mm Hand Plating System in Type AO 33-A3 Distal Femur Fracture - Technical Note -: Bong-Ju Lee, Ja-Yeong Yoon, Seungha Woo; J Korean Fract Soc 2023;36(1):25-28.

Abstract PDF: Open reduction in an AO 33-A3 class distal femur transverse and comminuted fracture is often difficult due to frequent reduction loss during surgery, leading to longer operative time and increased blood loss intra-operation. In this study, the authors report a case in which the use of an offset grid plate (OsteoMed, USA) using 2.4 mm HPS (hand plating system) eased the process of fracture reduction and achieved a stable internal fixation, ultimately leading to successful osteosynthesis. The authors experienced no need for temporary fixation devices such as K-wires or screws, which are otherwise required to stabilize the reduction. The fracture reduction was stable throughout the primary fixation of the fracture using a locking plate and screws. The authors report that the advantage of the HPS plate is fitting into the cortical contour and providing stable maintenance of fracture reduction intra-operation, which would be beneficial in certain distal femoral fracture patterns.

Shoulder Quadruple Dislocation Fracture: Fracture of Glenoid Rim, Coracoid Process, Greater Tuberosity, Surgical Neck of Humerus Associated with Anterior Shoulder Dislocation: A Case Report: Jae sung Yoo, Seong jun Kim, Seung gwan Park, Joong Bae Seo; J Korean Fract Soc 2019;32(1):47-51. Published online January 31, 2019; DOI: https://doi.org/10.12671/jkfs.2019.32.1.47

Abstract PDF: Shoulder joint dislocation has the most common incidence rate compare compared to other joints. It is reported that shoulder Shoulder dislocation couldmay be associated with glenoid rim, greater tuberosity of humerus and coracoid process fracture. There were have only been 2 cases of anterior shoulder dislocation simultaneously combined with simultaneous glenoid rim, coracoid process, and humerus greater tuberosity fracture worldwide and no report reports in Korea. We present a case of quadruple fracture (glenoid rim, coracoid process, greater tuberosity, surgical neck of humerus) associated with anterior shoulder dislocation and treated successfully by open reduction. In addition, with we provide the injury mechanism, diagnosis, treatment procedure and discussion.

The Result of Conservative Treatment of Proximal Humerus Fracture in Elderly Patients: Seung Gil Baek, Chang Wug Oh, Young Soo Byun, Jong Keon Oh, Joon Woo Kim, Jong Pil Yoon, Hyun Joo Lee, Hyung Sub Kim; J Korean Fract Soc 2013;26(4):292-298. Published online October 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.4.292

Abstract PDF: PURPOSE
With the increase in the old age population, proximal humerus fractures have been increasing recently. However, complications after operative treatment, such as fixation failure, are common because of osteoporosis. We treated proximal humerus fractures in patients with osteoporosis conservatively, and evaluated the radiographic and functional results by analyzing the factors affecting the results.
MATERIALS AND METHODS
Nineteen out of 30 cases for whom the clinical follow-up was over 1 year were included in this retrospective study. There were 17 females and 2 males, and the mean age was 73.2 years. The causes were slip from a short height (18 cases) and a minor car accident (1 case). We evaluated the union period, nonunion, malunion and the Constant score and analyzed several factors affecting the functional result, such as age, fracture pattern, and malunion.
RESULTS
Seventeen cases (89.5%) obtained union within 12.8 weeks on average. Neck-shaft angle was 125.3degrees on average, with seven cases of malunion. The Constant score was 84.1 on average, and there were excellent scores in 11 cases, good scores in 4 cases, and fair scores in 2 cases. Fracture pattern, neck-shaft angle, or malunion did not affect the functional outcome, and elderly patients showed poorer shoulder function.
CONCLUSION
Proximal humeral fractures with osteoporosis may achieve a high rate of bony union when treated with conservative methods. Despite the common occurrence of malunion, a satisfactory functional outcome may be expected.

Prediction of Peroneal Tenosynovitis in the Intraarticular Calcaneal Fractures Using Computed Tomography: Jeung Tak Suh, Ju Young Jung, Hui Tak Kim, Chong Il Yoo, Seong Ho Hwang, Heung Tae Chung; J Korean Soc Fract 2000;13(3):537-543. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.537

Abstract PDF: PURPOSE
The purpose of the current study is that CT can predict peroneal tenosynovitis in the intraarticular calcaneal fracture.
MATERIALS AND METHOD
Sixty five calcaneal fractures in 55 patients were evaluated with CT scan. The follow-up period after operation was averaged 19 months (ranging from 4 to 79 months). A classification for peroneal tendon injury was developed, based on CT scan.
RESULTS
Of the 65 intraarticular calcaneal fractures, the incidence of peroneal tenosynovitis were 14 cases(26%)[open reduction and internal fixation group 7/43(16%), Essex-Lopresti group 7/22(32%)]. According to the author's classification, the incidence of peroneal tenosynovitis among open reduction and internal fixation subgroup was followed ; type I was none(0/4), type II 11%(2/19), type III 20%(3/15) and type IV 40%(2/5) respectively(p=0.074). The incidence of peroneal tenosynovitis among Essex-Lopresti subgroup was followed ; type I was none(0/4), type II 16%(1/6), type III 33%(3/9) and type IV 100%(3/3) respectively(p=0.009).
CONCLUSION
CT can be used to evaluate the status of the peroneal tendon as well as to predict the development of peroneal tenosynovitis. The open reduction and internal fixation in type III and IV is preferable to achieve a alignment of peroneal tendon and a accurate reduction of subtalar joint.
