Clinical Outcomes of Distraction Osteogenesis in Fourth Brachymetatarsia / 대한정형외과학회잡지

Purpose@#Brachymetatarsia is a relatively rare disease that is characterized by one or more metatarsals shorter than the adjacent metatarsal bones by 5 mm or more. Corrective treatment is done, not only for cosmetic purposes but also to improve function. The aim of this study was to evaluate radiologic and clinical results after distraction osteogenesis using external fixators for the fourth brachymetatarsia. @*Materials and Methods@#From January 2005 to September 2018, 45 patients (60 cases) with brachymetatarsia who underwent distraction osteogenesis using external fixators and who were followed up for at least 6 months were studied retrospectively. At the final follow-up, the application time of the external fixator was measured and the percentage of lengthening, healing index, complication, and the patient’s satisfaction were analyzed. The patient’s satisfaction was evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) scores, based on the level of stiffness, pain, function, and alignment. @*Results@#The average gain in length and the percentage increase in the fourth metatarsals were 13.8 mm and 30.0%, and the mean followup period was 14.2 months after the removal of the external fixator. Bony union was obtained in the metatarsal bones in almost all the cases except for one case of non-union. According to the AOFAS score, 39 cases were rated excellent, and 6 cases were good at the final follow-up. The patients showed satisfactory cosmetic and functional results. Complications were pin site infections in 3 cases, all improved by oral antibiotic administration and dressing for about 2 weeks. Decreased sensation of the distal phalanx occurred in one case, and there was one case of non-union where we performed revision with an autogenous bone graft. In one case metatarsal joint subluxation occurred due to angular deformity, for which corrective osteotomy was performed. @*Conclusion@#Satisfactory results were obtained after distraction osteoplasty using external fixation for the treatment of the fourth brachymetatarsia.

Outcomes of Immediate Operative Treatment of Ankle Trimalleolar Open Fractures / 대한족부족관절학회지

PURPOSE: Generally, the treatment of ankle trimalleolar open fractures is divided into two stages: external fixation and debridement; and secondary internal fixation. On the other hand, this two-stage operation takes considerable treatment time and is challenging in procedures requiring reduction. The purpose of this study was to evaluate the radiologic and clinical results of an immediate one-stage internal fixation operation considering the wound conditions to overcome two stage operation disadvantages.MATERIALS AND METHODS: From September 2009 to January 2018, 24 cases of ankle trimalleolar open fractures, who underwent immediate internal fixation and were followed up for at least one year, were studied retrospectively. The open wound was divided into the Gustilo-Anderson classification. Open reduction and internal fixation were performed on every medial and lateral malleolar fracture. On the other hand, with posterior malleolar fractures, surgical or conservative treatment was performed depending on the fragment size. The radiologic outcome was evaluated using the Burwell and Charnley criteria and American Orthopaedic Foot and Ankle Society (AOFAS) scores, and complications, such as infection and posttraumatic arthritis, were used for the clinical evaluation.RESULTS: The wound was classified into eight cases (33.3%) of type I, 11 cases (45.8%) of type II, and five cases (20.8%) of type IIIa. The degree of reduction was anatomical, fair, and poor in 16 cases (66.7%), six cases (25.0%), and two cases (8.3%), respectively. The mean AOFAS score was 79 points, and there were complications, such as infection in three cases (12.5%) and post-traumatic arthritis in two cases (8.3%).CONCLUSION: Satisfactory results were obtained through immediate surgical treatment in ankle trimalleolar open fractures of types I, II, and IIIa.

Treatment of Multiple Thoracolumbar and Lumbar Spine Fractures: Comparison of Contiguous and Non-Contiguous Fractures in Non-Osteoporotic Patients / 대한척추외과학회지

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the outcomes of multiple thoracolumbar and lumbar fractures depending on whether the fractures were contiguous. SUMMARY OF THE LITERATURE REVIEW: The treatment of multiple spine fractures in patients without osteoporosis has rarely been reported. MATERIALS AND METHODS: From February 2004 to January 2016, 81 patients without osteoporosis who had acute thoracolumbar and lumbar fractures and underwent posterior fusion surgery were evaluated. Patients were divided into 2 groups (group A: contiguous, group B: non-contiguous). We investigated the causes of the injuries, the locations of the injuries within the spine, the range of fusion levels, and functional outcomes based on the patients' general characteristics. RESULTS: Group A comprised 37 patients and group B comprised 44 patients. In most patients, the fusion included 3 segments (group A: 12, group B: 14) or 4 segments (group A: 9, group B: 10). Group A scored 21.2 and group B scored 19.0 on the Korean Oswestry Disability Index. In both groups, longer fusion was associated with poorer clinical results. In the clinical evaluation of the fusion rate, there was no statistically significant difference between the 2 groups (p=0.446). CONCLUSIONS: In this study, patients with multiple vertebral fractures showed more fusion segments and poor clinical outcomes in contiguous fractures. In the patients with non-contiguous fractures, the clinical results were better when a minimal number of segments was fused. Therefore, the authors recommend conservative treatment to minimize the number of segments that are fused in non-contiguous multiple thoracolumbar and lumbar fractures when decompression is not necessary.

Comparison of Blood Loss between Intra-Articular and Intravenous Tranexamic Acid Following Primary Total Knee Arthroplasty / 대한정형외과학회잡지

PURPOSE: To investigate the difference in blood loss between two injection methods, intravenous (IV) and intra-articular (IA) methods via drain tube. MATERIALS AND METHODS: A total of 183 patients who underwent total knee arthroplasty between October 2013 and March 2016 were included. The method of tranexamic acid (TXA) administration was intravenously injected before August 2015, and it was applied thereafter to the joint through a drainage tube post intra-articular suture. Our subjects were divided into the following groups: The intravenous unilateral (IVU), intravenous bilateral (IVB), intra-articular unilateral (IAU), and intra-articular bilateral (IAB) groups. Hemoglobin and hematocrit, drainage amount, transfusion frequency, mean transfusion volume, and blood loss, as well as complications were compared between the groups. RESULTS: Drainage amount was 558.08±296.29 ml in IVU, and 498.39±199.70 ml in IAU; there was less drainage in IAU than in IVU, but without significance (p=0.262). Moreover, the drainage amount was 1,110.39±396.23 ml in IVB and 827.14±282.47 ml in IAB, which was significantly lower in IAB (p=0.000). Transfusion frequency was 5 patients (10.0%) in IVU and 2 patients (4.5%) in IAU, but without significant difference (p=0.442). Moreover, the frequency was 16 patients (29.6%) in IVB and 1 patient (2.9%) in IAB, which was significantly lower in the IAB group (p=0.002). Mean transfusion volume was 44.80±144.71 ml in IVU and 21.80±106.86 ml in IAU, but without significant difference (p=0.389); the volume was 177.80±321.00 ml in IVB and 18.30±108.18 ml in IAB, with statistical significance (p=0.001). Blood loss was 1,318.70±724.20 ml in IVU and 963.28±454.03 ml in IAU, which was significantly lower in the IAU (p=0.006); blood loss was 1,837.40±699.70 ml in IVB, and 1,337.60±382.20 ml in IAB and it was significantly lower in IAB (p=0.000). Complications included deep vein thrombosis in one case in IVU. CONCLUSION: In TKA, IA injection of TXA significantly reduced blood loss compared with IV injection, especially in bilateral TKA.

Perioperative Comparison of Hip Arthroplasty Using the Direct Anterior Approach with the Posterolateral Approach / 대한고관절학회지

PURPOSE: The aim of the current study is to report the advantage and disadvantage of total hip arthroplasty performed in direct anterior approach (DAA) by comparing it to the posterolateral approach (PLA). MATERIALS AND METHODS: Twenty-five hip arthroplasty done in DAA (12 total hip arthroplasty [THA] and 13 bipolar hemiarthroplasty [BHA]) were compared with the same number done in PLA (13 THA and 12 BHA). Intraoperative assessments including operation time, anesthetic time, bleeding amount were recorded with intraoperative complications. Immediate postoperatively, position of the prosthesis and leg length discrepancy were measured and were compared between the two approaches. RESULTS: The operation time was 22 minutes and 19 minutes longer in DAA for THA and BHA respectively while the anesthetic time difference was 26 and 10 respectively. However, these parameters showed no statistical difference. No significance was found when bleeding amount was compared. For DAA, cup alignment was within safe zone in 100% both for inclination and for anteversion while this was 83.3% and 75.0% respectively in PLA. Leg length difference was 3 mm in DAA and 5 mm in PLA but had no significant difference. Tensor fascia lata tear was the most common complication occurring in 9 patients. CONCLUSION: Although significant was not reached there was trend toward more operation time and anesthetic time when DAA was used. However, the trend also showed that cup and stem were likely to be in more accurate position and in adequate size which is likely due to the accurate use of fluoroscopy.

Paraplegia in an Ankylosing Spondylitis Patient with a Neglected Spine Fracture after Osteosynthesis for Fracture of the Femur: A Case Report

STUDY DESIGN: Case report. OBJECTIVES: To report a case of paraplegia in a patient with thoracic kyphosis after osteosynthesis for a fracture of the femur. SUMMARY OF LITERATURE REVIEW: There are few reports about cases of paraplegia after low extremity fracture surgery in patients with thoracic kyphosis with ankylosing spondylitis. MATERIALS AND METHODS: An 86-year-old female patient presented with right hip pain. She had undergone surgery for an intertrochanteric fracture of the femur in the supine position under general anesthesia. Immediately after surgery, she showed paraplegia. Postoperative thoracolumbar spine images revealed a fracture through the disc at T12 and L1. However, she did not complain of back pain or any neurologic deficits before surgery. RESULTS: Although the patient underwent emergent posterior decompression and fusion surgery, her neurologic compromise did not improve during 1 year of follow-up. CONCLUSIONS: It is necessary to check preoperative spine radiographs before surgery in elderly patients who have a kyphotic deformity and lower extremity fractures. Surgeons should consider changing the position of the patient and the type of anesthesia used during surgery when spine stability is in doubt.

Predictors and Clinical Features of Long-term Continuous Ambulatory Peritoneal Dialysis(CAPD) / 대한신장학회잡지

Although CAPD has become firmly established as an effective mode of renal replacement therapy, it's technique survival rate is much inferior compared to hemodialysis. To date, few patients have been maintained on this therapy for more than 10 years. To gain insights into clinical features of patients who had maintained over 10 years on CAPD in Korea, we retrospectively compared 23 patients who survived more than 10 years on PD(Long-term survivors, LTS) and 63 patients who died(Short-term survivors, STS-died, 41 patients) or changed to hemodialysis(STS-HD, 22 patients) within 4 years of initiating PD. For all patients, age, sex, diabetic history, prior cardiac events, body weight and biochemical profiles were analyzed. 1) The LTS were younger(39.7+/-12.4 vs. 47.7+/-12.3 vs. 60.9+/-13.8 years) compared with STS-HD and STS-died. 2) The LTS had less cases of DM(4.3% vs. 31.8 % vs, 61%), and had less cases of prior cardiac events(4.3% vs. 4.5% vs, 34.1%) compared with STS-HD and STS-died. Sex ratio and body weight were comparable in three groups. 3) At the initiation of PD, the LTS had higher serum creatinine(16.7mg/dL vs. 12.4mg/dL vs, 8.4mg/dL), albumin(3.53g/dL vs. 3.27g/dL vs, 3.20g/dL) levels compared with STS-HD and STS-died. 4) During 10 year CAPD treatment, LTS showed relatively stable body weight except the increase of body weight for the first 2 years in female. BUN, creatinine, protein, albumin constantly increased for the first 4 years, and then started to decline by 4 th to 6 th years. In conclusion, young age, non-diabetic history, less prior cardiac events and good nutritional status can predict the long-term survival on peritoneal dialysis. The evaluation of nutritional status and nutritional support by 4 th to 6 th years may be important in maintaining long-term survival in CAPD patients.

Nutritional Status of Long-term CAPD Patients-Impact of Peritoneal Transport Characteristics / 대한신장학회잡지

Protein-calorie malnutrition is common in CAPD patients and is associated with increase in morbidity and mortality in CAPD patients. There are many causes of malnutrition in CAPD patients, and it is well known that a large amount of protein losses through peritoneal membrane is one of them. To investigate the effect of the peritoneal membrane transport characteristics on the nutritional status in long-term CAPD patients, we conducted a cross- sectional study on clinically stable 115 patients (63 males and 52 females) who have been on CAPD for more than 2 years, and assessed nutritional status by subjective global assessment (SGA), biochemical, anthropometric and urea kinetic parameters. Patients were divided into 4 groups according to the results of standard peritoneal equilibration test (PET). The results were as follows: 1) The patients were divided into 4 groups according to the PET results: high transporter (n=16, 14%), high average transporter (n=38, 33%), low average transporter (n=50, 43%), and low transporter (n=11, 10%). 2) The mean age of the patients was 50.1+/-11.6 years (range, 19-75) with sex ratio (M:F) 1.2:1 and mean duration of dialysis was 57.5+/-27.8 months (range, 24-135). The mean body weight (Bwt) was 59.2+/-8.9kg, percent ideal body weight (%IBW) was 104.7+/-15.6%, %lean body mass (LBM)/Bwt was 82.1+/-11.1%, and malnourished patients by subjective global assessment (SGA) were 32.2% (38/115). 3) The mean BUN, creatinine, total protein, and albumin level of the patients were 54.5+/-13.1mg/dL, 12.3+/-3.0mg/dL, 6.7+/-0.8g/dL, and 3.8+/-0.6g/dL, respectively. 4) There were no significant differences in age, sex ratio, CAPD duration, peritonitis rate, %LBM/ Bwt, and SGA among the 4 groups. 5) Total protein (g/dL) and albumin (g/dL) levels in high transporters were 6.4+/-0.5, 3.5+/-0.4, respectively, and they were significantly lower than those of low transporters (7.2+/-0.6, 4.2+/-0.5) (P<0.05). 6) 24 hour dialysate protein (g/day) and albumin (g/day) losses were significantly higher in high transporters (8.10+/-1.85, 4.19+/-1.23) compared to those of low transporters (5.07+/-1.85, 2.78+/-0.99) (P<0.05). 7) The level of IGF-1 (ng/mL) was significantly lower in high transporters (150.5+/-86.2) compared to that of low transporters (310.3+/-162.1) (P<0.05). 8) The level of BUN (mg/dL), Cr (mg/dL) were also lower in high transporters (45.4+/-13.1, 10.1+/-2.0) than those of low transporters (61.6+/-18, 14.7+/-2.7), but there were no significant differences in Hct, total cholesterol, prealbumin, and transferrin among the 4 groups. 9) There were no statistically significant differences in Kt/Vurea, RRF, NPCR, dietary calorie and protein intakes among the 4 groups. 10) Anthrometric parameters such as TSF, BSF, MAC and LBM measured by three different methods (LBMCr, LBMimp, LBManthro) didn't show any significant differences among the 4 groups. In conclusion, increased peritoneal permeability may not adversely affect SGA and anthropometric status of long-term CAPD patients, although it is associated with lower serum albumin, creatinine, and IGF-1 level. Clinical significance of these findings remains to be elucidated.

A Case of Optic Neuritis in Systemic Lupus Erythematosus / 대한내과학회지

Systemic lupus erythematosus (SLE) is a disease of unknown etiology in which tissues and cells are damaged by pathogenic autoantibodies and immune complexes. Optic neuritis in SLE is very rare and the prevalence can be estimated to be approximately 1% of the patients of SLE. The main pathogenesis of optic neuritis with SLE is that of a vaso-occlusive disease in small vessels and the histopathologic appearance has varied from demyelination to definite vascular disease with axonal necrosis. The visual outcome of optic neuritis in SLE has often been poor. The treatments of optic neuritis in SLE are intravenous methylprednisolone, immunosuppressive agents and plasmapheresis. The authors experienced a case of lupus nephritis and CNS lupus which was complicated by optic neuritis in 18-year-old female patient who complained of sudden visual disturbance of the both eyes After treatment with plasmapheresis and systemic corticosteroid, her visual deficit was gradually recovered.

Serum Albumin as a Predictor of Morbidity and Mortality in Continuous Ambulatory Peritoneal Dialysis(CAPD) Patients / 대한신장학회잡지

Serum albumin(SA) is a powerful predictor of morbidity and mortality in hemodialysis(HD) population. In CAPD patients, SA may be more severely compromised because of large dialysate protein losses and lower protein intake relative to HD patients. However, the usefulness of SA as a marker for increased morbidity and mortality in CAPD patients remains undefined. To investigate the role of SA and other risk factors as predictors of peritonitis, hospitalization and death in CAPD patients, we conducted this retrospective study on 782 patients who were followed-up for more than 3 months after initiation of CAPD at Severance Hospital from January 1985 through August 1995. For each patient the following data were collected: age, sex, duration on dialysis, presence of diabetes mellitus or cardiovascular disease, and monthly biochemical data including SA. 1) The mean age of the patients was 45.5+/-13.6 years(range, 14-80) with sex ratio 1.2:1 and mean duration on dialysis was 30.8+/-25.6 months(range, 3- 122). 2) Independent factors affecting serum albumin level were creatinine(beta=0.301, por=4.0g/dL), and incidence of peritonitis, hospitalization and death were compared among them. Compared to group 2 and group 3, group 1 had significantly higher peritonitis rate(1.18 vs. 0.87, 0.66 times/year/patient, p<0.05) and hospitalization(7.93 vs. 4.70, 3.36 days/year/patient, p<0.05). The 5- year survival rates in group 1, group 2 and group 3 were 43.4%, 60.9% and 84.1%, respectively (p<0.05). In conclusion, low SA is an important and strong predictor for morbidity and mortality in CAPD patients. Prospective studies are needed to determine if aggressive intervention with nutritional supplements could improve the SA level and to determine if such an improvement would impact on morbidity and mortality.
