임성안(Sung-An Lim),심승우(Seung-Woo Shim),백성년(Sung-Nyun Baek),박태규(Tae-Gyu Park),최용수(Yong-Soo Choi) 대한정형외과학회 2022 대한정형외과학회지 Vol.57 No.6
목적: 퇴행성 척추증 환자에서 흉-요추부 시상 지표와 제1요추 경사도의 관계를 분석하고, 젊고 건강한 연구 지원자와의 차이를 알아보고자 하였다. 대상 및 방법: 만성 요통 또는 배부통을 호소하는 평균 연령 72.00±10.00세의 36명을 1군으로, 요통을 호소하지 않는 평균 연령 29.3±4.97세의 지원자 20명을 2군으로 하였다. 두 군에서 제7경추 시상수직축(C7 sagittal vertical axis), 흉추후만각(thoracic kyphosis), 요추전막각(lumbar lordosis), 제1흉추 경사도(T1 slope), 천추 경사도(sacral slope), 골반 경사각(pelvic tilt), 골반 지수(pelvic incidence), 제1요추 경사도(L1 slope)를 기립 측면 전신 방사선 검사를 통해 측정하여, 제1요추 경사도와 흉-요추부 시상 지표와의 관계를 분석하였다. 결과: 제1요추 경사도는 1군에서 2.70±12.66°, 2군에서 12.24±4.08°였고, 두 군 간에 유의한 차이가 있었다(p<0.001). 제1요추 경사도는 2군에서 제1흉추 경사도, 흉추후만각과 양의 상관관계(R<SUP>T1 slope</SUP>=0.448, R<SUP>TK</SUP>=0.537)를 가졌고, 1군에서는 흉추후만각, 요추 전만각 및 천추 경사도와 양의 상관관계(R<SUP>TK</SUP>=0.480, R<SUP>LL</SUP>=0.774, R<SUP>SS</SUP>=0.385)를 가졌으며, 제7경추 시상수직축과 음의 상관관계(R<SUP>C7-SVA</SUP>=-0.529)를 보였다. 전체 연구대상자 분석에서 제1요추 경사도는 흉추후만각, 요추 전만각, 천추 경사도와 양의 상관관계로 확인되었고(R<SUP>TK</SUP>=0.466, R<SUP>LL</SUP>=0.790, R<SUP>SS</SUP>=0.409), 제7경추 시상수직축, 골반 경사도와 음의 상관관계로 확인되었다(R<SUP>C7-SVA</SUP>= -0.608, R<SUP>PT</SUP>=-0.364). 결론: 퇴행성 척추증의 경우 요추 전만각이 감소하고 이로 인해 흉추후만각이 감소, 제7경추시상수직축이 증가하고, 제1요추 경사도는 감소하는 양상을 보여 제1요추 경사도가 퇴행성 척추증 환자들의 흉-요추부 시상 정렬을 이해하는데 도움이 될 수 있을 것으로 생각된다. Purpose: To identify the characteristics of the L1 slope in the thoracolumbar sagittal parameters of degenerative spondylosis through comparison with healthy young people. Materials and Methods: Thirty-six patients who had chronic back and lower back pain were classified as Group I and twenty healthy people were as Group II. The average age of subjects in the Group I was 72.00±10.00 years and that of, Group II was 29.3±4.97 years. Radiographic parameters such as the C7 sagittal vertical axis (SVA), thoracic kyphosis (TK), lumbar lordosis (LL), T1 slope, sacral slope (SS), pelvic tilt (PT), pelvic incidence, and L1 slope were measured on whole-spine lateral radiographs taken with the patient standing. We analyzed the relationships between the L1 slope and other parameters. Results: There were significant differences between the two groups. the mean L1 slope was 2.70±12.66° in Group I and 12.24±4.08° in Group II (p<0.001). In the healthy young group, the T1 slope and TK had a positive correlation with the L1 slope (R<SUP>T1 slope</SUP>=0.448, R<SUP>TK</SUP>=0.537). In the degenerative spondylosis group, the L1 slope had a positive correlation with TK, LL and SS (R<SUP>TK</SUP>=0.480, R<SUP>LL</SUP>=0.774, R<SUP>SS</SUP>=0.385) and a negative correlation with C7-SVA (R<SUP>C7-SVA</SUP>=-0.529). Taking both groups together, the L1 slope had a positive correlation with TK, LL and SS (R<SUP>TK</SUP>=0.466, R<SUP>LL</SUP>=0.790, R<SUP>SS</SUP>=0.409) and a negative correlation with C7-SVA and PT (R<SUP>C7-SVA</SUP>=-0.608, R<SUP>PT</SUP>=-0.364). Conclusion: In degenerative spondylosis, LL may decrease, which leads to a decrease in the TK, an increase in the C7-SVA, and a decrease in the L1 slope. These results suggest that the L1 slope could be helpful in understanding the thoracolumbar sagittal alignment.

Purpose: To figure out how complete control of family visits to prevent infection of coronavirus disease 2019 (COVID-19) affected the activity recovery of hip fracture patients admitted to nursing hospitals. Materials and Methods: Eighty-one patients with hip surgery in the two years prior to COVID-19 pandemic were classified as Group A, and 103 patients in the next two years were designated as Group B. The subjects’ walking ability was evaluated by using the modified Koval index (MKI). In order to analyze the impact of the family visit control to the subjects, each group was classified into two different groups: (1) inpatients group who admitted to nursing hospitals and (2) home-treated patients. Additionally, statistical elements were processed in consideration of other factors that may affect the results of the experiment. Results: The MKI evaluated at 6 months postoperative was 3.31±1.79 in Group A and 2.77±1.91 in Group B, and it was meaningfully low after the pandemic (P=0.04). There was significantly low among both of Group A 2.74±1.76 and Group B 1.93±1.81 after the pandemic (P=0.03) among those treated at the nursing hospital. The rate of deterioration of the MKI was 35 (43.2%) in Group A and 57 (55.3%) in Group B, which increased by 12.1% after the pandemic. Conclusion: The pandemic had a negative effect on the recovery of postoperative activities of elderly hip fracture patients who admitted to nursing hospitals when family access was completely restricted to prevent infection.

Background: The aim of this study was to determine if it was feasible and safe to perform total hip arthroplasty (THA) using the direct anterior approach (DAA) when compared with the conventional posterolateral approach (PA) in patients with femoral neck fractures. The time required to start walking was investigated to identify advantages of the muscle-sparing approach. Safety of the approach was judged based on the incidence and nature of all complications. Methods: We retrospectively reviewed 67 THA cases due to femoral neck fractures from October 2015 to January 2019. The PA was used in 31 cases, and the DAA was used in 36 cases. The average operative time and amount of bleeding were evaluated. Cup inclination, anteversion, and leg length discrepancy (LLD) were also measured on radiographs. The time to start walking and complications (e.g., intraoperative fracture, infection, and dislocation) were recorded. Results: The mean operative time was 84.35 ± 13.95 minutes in PA group and 99.22 ± 20.33 minutes in DAA group (p = 0.010). But after experiencing 20 cases using the DAA, there was no statistically significant difference in the operative time between the groups. The mean volume of bleeding was 428.73 ± 207.26 mL in the PA group and 482.47 ± 150.14 mL in the DAA group. There was no difference in the acetabular cup position between two groups. Ambulation was started at 3.94 days after surgery on average in the PA group and 3.14 days in the DAA group, showing a statistically significant difference. Intraoperative fracture and infection were not observed in either group. The incidence of LLD was 1 in each group. The dislocation rate was 3.2% (1 case) in the PA group and 5.5% (2 cases) in the DAA group. Conclusions: Although the DAA for THA was similar to the PA in terms of operative time, volume of bleeding, and complications, the DAA showed a great advantage in early rehabilitation as a muscle-sparing procedure in the elderly with femoral neck fractures.

Purpose: The purpose of this study was to determine whether the direct anterior approach (DAA) can be applied to hemiarthroplasty for treatment of unstable femoral intertrochanteric fractures in elderly patients. Materials and Methods: We conducted a retrospective review of 34 cases (34 patients) who underwent bipolar hemiarthroplasty using a DAA from February 2019 to April 2020. The mean age of the patients was 82.68 years (range, 67-95 years). A cementless distal fixation hip system was used in all cases. Operation time, total amount of blood loss, intraoperative and postoperative fractures, infections, and reoperations were measured. The patients performed weight-bearing walking as tolerated immediately after surgery. Measurement of migration of the greater trochanter (GT) and progressive subsidence of the femoral stem was performed using follow-up radiographs. Results: The mean operative time was 83.50 minutes (range, 60-120 minutes). The mean amount of bleeding was 263.53 mL (range, 112-464 mL). Walking started a mean of 3.03 days (range, 3-4 days) after surgery. There was no case of progressive migration of the GT more than 5 mm even though it was not fixed. There were no cases of infection, dislocation, or reoperation. Conclusion: Bipolar hemiarthroplasty using the DAA for treatment of unstable femoral intertrochanteric fractures could be considered a useful option that provides many advantages in elderly patients.

Park Ji-Hun,이상민,Shim Seong-Woo,Baek Sung-Nyun,Choi Yong-Soo 대한척추외과학회 2021 Asian Spine Journal Vol.15 No.5
Study Design: A cross-sectional study. Purpose: To examine the influence of restrictive pulmonary dysfunction on osteoporotic thoracic vertebral fractures. Overview of Literature: Osteoporotic thoracic vertebral fractures generally result in an increased kyphotic angle, which in turn may lead to pulmonary function impairment. Impaired pulmonary function could be associated with vertebral fractures. However, an association between osteoporotic thoracic vertebral fractures and pulmonary function remains controversial. Methods: A total of 96 patients were enrolled in this study, 30 of whom had osteoporotic thoracic vertebral fractures (group 1), 30 with chronic back pain (group 2), and 36 with chronic pulmonary diseases (group 3). Radiologic study of prevalent vertebral fractures, thoracic kyphotic angle, bone mineral density, relaxed expiratory vital capacity, forced vital capacity (FVC), and forced expiratory volume in 1 second (FEV1) in spirometry was investigated. Results: The mean FVC and FEV1 were 75.66%±20.23% and 79.93%±22.48%, respectively, in group 1; 84.50%±16.25% and 91.87%±21.65%, respectively, in group 2; and 91.64%±17.53% and 91.03%±23.71%, respectively, in group 3. Group 1 (patients with osteoporotic thoracic vertebral fracture) had the lowest FVC among the three groups (p=0.01). Group 1 revealed worse result of pulmonary dysfunction than group 3 (patients with chronic pulmonary diseases) (p=0.01). The average kyphosis angle of the thoracic spine was 26.95°±15.17°, 36.47°±20.08°, and 28.58°±10.58° in groups 1, 2, and 3, respectively. There was a negative correlation between thoracic kyphosis and FEV1 (r=−0.309, p=0.01). Conclusions: The results suggest that osteoporotic thoracic vertebral fracture burden could be affected by restrictive pulmonary dysfunction.
