Surgical Treatment for Displaced Intra-Articular Calcaneal Fractures in Elderly Patients: Comparison of the Minimally Invasive Approach and Extensile Lateral Approach: Hong Ki Park, Jae Yoon Ko, Seung Kwan Lee, Jong Min Baik; J Korean Fract Soc 2019;32(3):135-142. Published online July 31, 2019; DOI: https://doi.org/10.12671/jkfs.2019.32.3.135

PURPOSE
As the functional demands for activities in elderly patients are increasing according to their life extension, the need for surgical treatment is also increasing in elderly patients with displaced intra-articular calcaneal fractures. In addition to the extensile lateral approach (ELA), which is a surgical procedure that showed good results on intra-articular calcaneal fractures, the minimally invasive approach (MIA) also showed an outstanding result. This study compared the radiological and clinical results of intraarticular calcaneus fractures in elderly patients in two groups: ELA and MIA.
MATERIALS AND METHODS
Thirty patients aged over 65 years with intra-articular calcaneus fractures, who could be followed-up more than 14 months, were included in this study. Thirteen patients of the MIA group and 17 patients of the ELA group were analyzed retrospectively using radiological and clinical assessments.
RESULTS
No significant difference in union time, posterior facet reduction accuracy, subtalar osteoarthritis frequency, Bohler angle, calcaneal width, American Orthopaedic Foot and Ankle Society score, visual analogue scale score, 36-item short form survey, and foot function index was observed between the two groups. The p-value of the average height of the calcaneus correction, average length of calcaneal correction, and average loss of correction length were <0.001, 0.005, and 0.015, respectively. The incidence of complications, including soft tissue necrosis and bone infection, were 23.1% in the ELA group and none in the MIA group.
CONCLUSION
The clinical outcomes were similar in the two groups. The degree of reduction of fracture showed a better result in the MIA group than the ELA group. Furthermore, there were no complications in the MIA group, whereas the ELA group showed some complications.

The Significance of Calcaneal Posterior Tuberosity Fragment Reduction When Treated with Open Reduction in Displaced Intra-Articular Calcaneal Fractures: Hong Ki Park, Jong Ryoon Baek, Jang Seok Choi, Sang Jin Lee, Je Won Paik; J Korean Fract Soc 2016;29(4):233-241. Published online October 31, 2016; DOI: https://doi.org/10.12671/jkfs.2016.29.4.233

Abstract PDF: PURPOSE
We attempt to evaluate the significance of calcaneal posterior tuberosity fragment reduction when treated with surgical open reduction in displaced intra-articular calcaneal fractures.
MATERIALS AND METHODS
A total of 90 patients with displaced intra-articular calcaneal fracture, between January 2010 and December 2015, treated with open reduction and internal fixation were enrolled in this study. At postoperative 3 months, we evaluated the reduction state of calcaneal posterior tuberosity fragment by measuring the degree of lateral displacement of the posterior tuberosity fragment on the calcaneal axial view. Moreover, we also evaluated the difference in the calcaneal length and height with the uninjured side on the lateral view of both sides. In addition, we estimated the reduction state of the posterior facet by measuring the degree of gap and step-off on the semi-coronal view of postoperative computed tomography and estimated the restoration of calcaneal angle by measuring the difference in BÃ¶hler's and Gissane angle with the uninjured side on the lateral view of both sides.
RESULTS
The correlation coefficient with 3 components for evaluating the reduction state of posterior tuberosity fragment and gap and step-off of posterior facet was r=0.538, 0.467, r=0.505, 0.456, r=0.518, and 0.493, respectively, and restoration of BÃ¶hler's and Gissane angle was r=0.647, 0.579, r=0.684, 0.630, r=0.670, and 0.628, respectively. The relationship of each component shows a significant correlation as all p-values were <0.01.
CONCLUSION
The precise reduction of calcaneal posterior tuberosity fragment developed by the primary fracture line was considered as an important process of anatomical reduction of calcaneal body, including the posterior facet and calcaneal angle restoration.

Clinical Study on Operative Technique and Management of Tibial condylar Fractures: Su Chan Lee, Beom Koo Lee, Do Hyun Moon, Jin Hong Ko, Young Kyu Kim, Hong Ki Park, Jun MO Jung, Hyun Park; J Korean Soc Fract 1998;11(3):533-539. Published online July 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.3.533

Abstract PDF: We reviewed fifteen cases of tibial condylar fractures, especially, Schatzker type VI treated with hybrid method from January 1995 to May 1997. We attained satisfactory bony union in all cases. There were not serious complications such as deep wound infection and severe angular deformity, but partial ankylosis. After operation, the patients could do knee motion exercise immediately and had no difficulty in getting maintenance of reduction and fracture healing. In conclusions, the hybrid method is an excellent treatment in soft tissue care, maintenance of reduction, and early ambulation and fracture healing in the cases of tibial condylar fractures.

A Comparison of Unlearned IM-nailing with Reamed IM-nailing in Tibial Shaft Fracture: Su Chan Lee, Bum Gu Lee, Do Hyun Moon, Jin Hong Ko, Hong Ki Park, Ki Dong Kang, Sang Kyoo Choi; J Korean Soc Fract 1997;10(2):295-302. Published online April 30, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.2.295

Abstract PDF: Recently, there is seen frequently the tibial fracture due to the increased traffic accident and the high industry. Rigid intramedullary nailing is the method of choice in tibial shaft fracture, early weight bearing and joint motion. Between Jan.1993 and Dec. 1994, we treated 93 tibial shaft fractures with reamed intramedullary nails(55 cases) & unlearned intramedullary nails(38 cases). We analyzed the effects of these two methods, and the following results were obtained. 1. Of 93 fractures, 32 fractures were open and 61 fractures were closed. 2. The most common cause was traffic addicent. Among the 93 cases, 60 cases were male and 33 cases were female, the most common age were ranged from 30-39 year, involving 36 cases. 3. The mean durations of the bone union were 19.7 weeks in closed fracture with treated by reamed nail and 22.1 weeks in closed fracture with unlearned. The mean duration of the bone union were 24.5 weeks in open fracture with reamed and 22.4 weeks in open fracture with unlearned. The complications of intramedullary nail are angular deformity, infection, delayed and nonunion, and screw breakage.

Operative Tleatment of the Lateral Condyle Fractures of the Humerus in Children: Bum Gu Lee, Do Heun Moon, Jin Hong Ko, Su Chan Lee, Hong Ki Park, Ki Dong Kang, Young Kim; J Korean Soc Fract 1996;9(4):1096-1103. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.1096

Abstract PDF: Fracture of the lateral humeral condyle is a relatively common injury in children. The standard treatment of Jakobs type II and III fractures is open reduction and internal fixation The treatment of Jakobs type I fractures is more controversial. Authors performed clinical and radiological analysed of fifty-two patients of lateral condylar fracture of the humerus who have been treated with open reduction and internal fixation. They were followed up from one year to five years and two months. The results were as follows; 1. The age incidence was confined from 3 years to 12 years. 2. There were 14 cases(26.9%) of Milch type I, 38 cases(73.8%) of Milch type II and according to Jakobs stage, 20 cases were stage I, 23 cases were stage II, 9 cases were stage III. 3. All cases were treated by open reduction and Internal fixation. 4. In 5 cases were lateral condyle overgrowth of the humerus, 2 cases were limited ROM of elbow joint. and 2 cases pin site loosening and superficial wound infections observed. And this complications did not resutt in significant clinical disabilites. 5. Respectively, according to the criteria of Hardacre 41 cases(78.8%) were excellent, 11 cases (21.1%) were good, and there was no poor case. 6. The fracture type and stage of displacement did not effect the flnal results. the complications, the complications are due to inaccurate reduction or insecure fixation. Therefore, open anatomical reduction and stable internal fixation is required to avoid complications, even in stage I displaced fractures.
