Avulsion Fracture of Calcaneus in Diabetic Patients
Sung Jin Park, Nam Yong Choi, In Tak Chu, Suk Ku Han, Ki Ho Nah, Hyun Seok Song, Jung Ho Kim

AbstractAbstract PDF
Avulsion fracture of the calcaneal tuberosity is an uncommon injury. Usually it occurs from indirect trauma, and can be seen in old patients with osteoporosis or in patients with diabetic neuropathy. Follow-up studies showed fracture healing in most cases, but skeletal deformity may develop in some cases. Therefore we should do plain X-ray evaluations in diabetic patients with foot and ankle pain, even though there have been no definite trauma history. Four cases of calcaneus avulsion fracture were treated operatively in diabetic patients, and reported.

Treatment of Intertrochanteric Fracture in Elderly Patients with Preservation of Calcar Femorale and Hemiarthroplasty
In Tak Chu, Jung Man Kim, Gun Yeon, Kwang Jae Ryu
J Korean Soc Fract 1997;10(1):31-36.   Published online January 31, 1997

AbstractAbstract PDF
Seven patients with femur fractures were treated with external fixators. The average age at fracture Intertrochanteric fracture of the femur, of which reported mortality ranges from 15% to 20%, usually occurs in the elderly and is usually comminuted and unstable. Many operative techniques have been developed for early exercise and walking ambulation to reduce mortality and morbidity, but they still have disadvantages. Few papers has been reported on hemiarthroplasty for intertrochanteric fracture in elderly patient, but they did not preserve the calcar femorale which is very impartant anatomic portion for weight transmission after hemiarthroplasty Therefore, the purpose of this paper is to analyze clinical outcome of hemiarthroplasty with preseuation of calcar femorale and wiring of greater trochanter for intertro chante ric fracture. From March 1993 through March 1995. 28 elderly patients had undergone hemiarthroplasty with preservation of calcar femorale and wiring of greater trochanter for the treatment of severely comminuted and osteoporotic intertrochanteric fractures. Mean follow-up period was 17.5 months ranging from 12 months to 28 months. The results obtained were as follows : 1. The most common type by Boyd-Griffin classification was II(73%). 2. Twenty five cases(83%) had osteoporosis, which was evaluated by Singh index. 3. The average operating time was 42.8 minutes and average hospitalifation period was 20.6 days. 4. Excellent functional results according to hip rating scale of Merie DAubigne were obtained in 24 cases(80%). 5. Creater trochanter fixed with wire was united in average 4.4months postoperatively. 6. One case(3%) developed loosening of implant at postoperative 13 months.

Isolated Dislocation of Tarsal Navicular Bone : A Case Report
In Tak Chu, Kyung Ho Yoo
J Korean Soc Fract 1997;10(1):86-90.   Published online January 31, 1997
DOI: https://doi.org/10.12671/jksf.1997.10.1.86
AbstractAbstract PDF
Isolated dislocation of the tarsal navicular is very rare and its mechanism of injury and treatment is not well established. In our case, the naricular is dislocated plantomedially resulting from hyperplantar flexion, abduction injury with longitudial axial load. Open reduction and internal fixation was required because of pulling by tibialis posterior tender There was no traumatic arthritis at talo-navicular joint and naviculo-cuneiform joint and no evidenc of avascular necrosis of the tarsal navicular at postoperative 15 months follow-up.

Operative Treatment of Intra-articular Calcaneal Fractures by Posterior Approaeh
Youn Soo Kim, Ckoong Seo Park, In Tak Chu, Hyoung Min Kim, Jae Duk Ryu
J Korean Soc Fract 1992;5(2):191-198.   Published online November 30, 1992

AbstractAbstract PDF
In contrast to the extra-articular calcaneal fractures, the treatment of intra-articular fractures is very difficult and the final result is not always satisfactory, because it has not only difficulties in the identification of the exact fracture pattern and an anatomical reduction of the fracture fragments, but also no principle of ideal treatment. Today, numerous controversies remain regarding the treatment of intra-articular calcaneal fractures, which include the need of reduction, the method of reduction, the surgical approach. the method of fixation, and the need of bone graft. We propose the posterior approach and longitudinal buttress screw fixation for the treatment of intra-articular calcaneal fractures. The posterior approach allows excellent visualization of the posterior facet of subtalar joint, and the longitudinal screw buttresses the posterior facrt fracture fragment of calcaneus. From Dec. 1990 to May 1992, 17 intra-articular calcaneal fractures out of 15 patients were treated by our surgical method and followed up (average, 9.2 months) in 12 cases out of 10 patients (2 bilateral cases). Seven cases were tongue type fractures and five were joint do- pression type. Operations were performed 5 to 15 days after accident(average, 92 days). Bone graft was performed only 3 cases. At last follow-up, there was no pain in 8 cases. intermittant dull pain in 3, and resting pain in 1. The Bohlers angle at post-accident and last follow-up were 5.9 and 30.7 in tongue type : 10.6 and 32.6 in joint depression type. The reduction of the fracturr fragments was maintained well and secondary deformities were not developed in all cases. Based on these findings in this study, most of the intra-articular calcaneal fractures can be reduced anatomically by posterior approach, and fracture fragment maintained by longitudinal buttress screw fixation.
