Comparative Study of Clinical Outcome of Three Surgical Techniques in the Achilles Tendon Rupture: Open Repair, Percutaneous Repair, and Minimal Incision Repair by Achillon / 대한족부족관절학회지

PURPOSE: This study compared the clinical outcomes of open repair, percutaneous repair, and minimal incision repair by Achillon in ruptured Achilles tendon. MATERIALS AND METHODS: The outcomes of 12 patients with open repair (group 1), 8 patients with percutaneous repair (group 2), and 10 patients with minimal incision repair by Achillon (group 3) from February 2013 to March 2016 were analyzed retrospectively. The postoperative clinical evaluations were done by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Arner-Linholm scale, mid-calf circumference difference, one-leg heel raise difference, visual analogue scale (VAS) for postoperative scarring, time to return to work, and complications. RESULTS: No significant difference in the AOFAS ankle-hindfoot score, Arner-Linholm scale, and time to return to work was observed among three groups (p=0.968, 0.509, and 0.585). The mean differences in the mid-calf circumference in groups 1, 2, and 3 were 1.09, 0.73, and 0.58, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.002). In addition, the mean VAS scores for postoperative scarring in groups 1, 2, and 3 were 7.0, 9.1, and 9.1, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.001). The mean differences in one-leg heel raising in groups 1, 2, and 3 were 2.03, 1.91, and 1.33, respectively; group 3 was significantly higher than groups 1 and 2 (p=0.010). The complications encountered were one case of deep infection in group 1 and one case of sural nerve hypoesthesia in group 2. CONCLUSION: Minimal incision repair by Achillon is recommended as an effective surgical treatment for Achilles tendon rupture because it minimizes the risk of complications, leads to an improved tendon strength and healing, and achieves cosmetic satisfaction.

Usefulness of Percutaneous Transluminal Angioplasty before Operative Treatment in Diabetic Foot Gangrene / 대한족부족관절학회지

PURPOSE: Diabetic foot gangrene has a high morbidity rate and a great influence on the quality of life. Amputation is an appropriate treatment if conservative treatment is impossible according to the severity of gangrene and infection. The purpose of this study was to evaluate the usefulness of preoperative percutaneous transluminal angioplasty for the postoperative outcome. MATERIALS AND METHODS: From February 2013 to April 2016, among 55 patients with diabetic foot gangrene, who require surgical treatment, percutaneous transluminal angioplasty was performed on patients with an ankle brachial index (0.9 and stenosis) 50% on angiographic computed tomography. The study subjects were 49 patients, comprised of 37 males (75.5%) and 12 females (24.5%). The mean age of the patients was 70.0±9.6 years. The treatment results were followed up according to the position and length of the lesion and the changes during the follow-up period. RESULTS: As a result of angiography, there were 13 cases of atherosclerotic lesions in the proximal part, 11 cases in the distal part and 25 cases in both the proximal and distal parts. As a result of the follow-up after angiography, in 13 patients, the operation was not performed and only follow-up and dressing were performed around the wound. Sixteen patients underwent debridement for severe gangrene lesions and 20 patients, in whom the gangrene could not be treated, underwent amputation (ray amputation or metatarsal amputation, below knee amputation). CONCLUSION: Preoperative percutaneous angioplasty in diabetic foot gangrene patients with peripheral vascular occlusive disease is simple, and 59.2% of the patients with diabetic foot gangrene could be treated by conservative treatment or debridement.

Supramalleolar Osteotomy for Moderate Degenerative Ankle Osteoarthritis / 대한족부족관절학회지

This paper reviews the indications and surgical technique of supramalleolar osteotomy as one of the treatments for moderate degenerative ankle osteoarthritis. Although it is technically demanding and requires extensive preoperative planning, supramalleolar osteotomy will be a good treatment option for moderate degenerative ankle osteoarthritis. The osteotomy is designed to shift the weightbearing axis to the lateral side of the ankle joint and unload the medial side of the joint. In our experience, a supramalleolar osteotomy is effective to the treatment of moderate ankle osteoarthritis with a small amount of preoperative talar tilt and varus or normal heel alignment.

The Analysis of the Outcome of Short- and Long-Segment Posterior Instrumentation for Thoracolumbar Bursting Fractures

STUDY DESIGN: A retrospective study. SUMMARY OF THE LITERATURE REVIEW: The reports comparing short- and long-segment instrumentation are insufficient. OBJECTIVES: To determine the postoperative results and to analyze relative factors affecting results between short- and long-segment instrumentation in thoracolumbar fractures. MATERIALS AND METHODS: From March 2006 to March 2012, 97 patients with thoracolumbar fracture were treated with posterior instrumentation. They were divided into 2 groups, the short- (Group I) and long-segment groups (Group II). To analyze factors affecting results, several factors including age, anterior column height (ACH), and the kyphotic angle were reviewed. For radiologic evaluation, postoperative and follow-up radiographs were evaluated by measuring the kyphotic angle and ACH. Additionally, the presence of complications was reviewed. RESULTS: Groups I and II consisted of 45, 52 cases and had mean ages of 50.3, 55.8 years, respectively. In Group I, the ACH increased from 44.2% to 75.3% postoperatively, and remained 72.8% at follow-up. The kyphotic angle decreased from 19.4degrees to 10.6degrees postoperatively, and remained at 12.8degrees at follow-up. In Group II, the ACH recovered from 41.6% to 76.4% postoperatively, and was 74.8% at follow-up. The kyphotic angle decreased from 21.6degrees to 12.6degrees postoperatively, and was 13.9degrees at follow-up. The canal compromise, age, and comminution were not directly related with results. However, the mean age of the 7 cases showing complications was 72 years, and the 7 cases had severe comminuted fractures. CONCLUSIONS: The short- and long-segment instrumentations of thoracolumbar fractures are not significantly different with respect to the results attained. However, in order to decrease complications, we should pay attention to age and fracture comminution.

Analysis of the Risk Factors and Clinical Outcomes of Femoral Intertrochanteric Fractures in Patients over 65 Years Old / 대한고관절학회지

PURPOSE: This study examined therelationship between the clinical outcome and risk factors of intertrochanteric femoral fractures in patients over 65 years old. MATERIALS AND METHODS: From January 2000 to March 2012, three hundred and twenty one patients older than 65 years, who underwent surgeryfor intertrochanteric femoral fractures, were evaluated. The following parameters wereanalyzed: the patient risk factors, such as age, sex, smoking, drinking history, cardiovascular disease, cerebrovascular disease and delayed days to surgery; admission day of the week; anesthetic method; operation time by perioperative care related to clinical outcome including postoperative mortality; and complications. RESULTS: An analysis of the risk factors revealedfemale patients to have a 13% higher mortality (P=0.043). Aduration of surgerylonger than 3 hours was associated with a 29.1% and 20.8% higher mortality and complication rate, respectively (P<0.001, P=0.027). Asurgical delay of four days or more after admission wasassociated with a 20.1% and 18.8% higher mortality risk and complication rate, respectively (P<0.001, P<0.001). Smoking, drinking history, underlying disease, anesthetic method, and operation time had no significant effect on the outcome. CONCLUSION: In addition to recognizing the importance of patient-related risk factors, modifying the operative factors, such as reducing surgical delays and method of anesthesia, can reduce the mortality and postoperative complications of intertrochanteric femoral fractures.

Comparison of Femoral Morphology and Bone Mineral Density between Femoral Neck Fractures and Trochanteric Fractures in 65+ Females / 대한고관절학회지

PURPOSE: To analyze, by radiograph, the difference in bone mineral density (BMD) and the proximal femoral morphology of females who are over 65 years old and have had either an intertrochanteric fracture or a femoral neck fracture. MATERIALS AND METHODS: One hundred twenty-five females over 65 years of age with femoral neck fractures or intertrochanteric fractures were examined for bone mineral density using computed tomography from April 2008 to March 2011. The bone mineral density was measured by dual-energy x-ray absorptiometry (DEXA). The morphology of the proximal femur was also measured by computed tomography in the unaffected hip. RESULTS: In the femoral neck fracture group, the mean BMD value was 0.563 g/cm2 in the femoral neck region and 0.753 g/cm2 in the intertrochanteric region. In the intertrochanteric fracture group, the mean BMD value was 0.457 g/cm2 in the femoral neck region and 0.656 g/cm2 in the intertrochanteric region. There are statistically significant differences between the femoral neck fracture and intertrochanteric fracture groups (P=0.029, 0.030). The mean cortical index was 0.59 in the femoral neck fracture group and 0.51 in the intertrochanteric fracture group. There are statistical differences between the femoral neck fracture and intertrochanteric fracture groups (P=0.001). CONCLUSION: The BMD of the proximal femoral neck and intertrochanteric regions of the intertrochanteric fracture group were significantly lower than that of the femoral neck fracture group. The cortical index was also significantly lower in the intertrochanteric fracture group than the femoral neck fracture group. BMD and computed tomography seem useful to check in women older than 65 who have fractures of the proximal femur.
