ObjectiveTo evaluate the conditions of activity of daily living (ADL) and influence factors of ADL of hospitalized elderly (≥60 years old) patients. MethodsA cross-sectional study was conducted to investigate the health and ADL conditions of hospitalized elderly patients in the geriatric department of a tertiary hospital in Chongqing by ADL scale. The influence factors of ADL were analysed by using logistic regression analysis. ResultsA total of 375 hospitalized elderly patients were included. The ADL impairment rate of female was 59.60% (93/156), the one of male was 75.90% (166/219), and there was significant difference between different sex (χ2=11.169, P=0.001). The impairment rate by age were 95.40% at 60 to 69 years old, 91.40% at 70 to 79 years old, 87.20% at 80 to 89 years old, and 98.55% at above 90 years old, respectively; there was significant difference among different age groups (χ2=8.575, P=0.036). The result of logistic regression analysis showed that age was the individual risk factor of ADL (OR=0.188, 95%CI 0.085 to 0.416, P=0.000). The difficulty of walking up and down stairs occupied the highest proportion (68.80%) in 10 items of ADL scale. ConclusionHospitalized elderly patients should be equipped with specialized paramedics to minimize the difficulties of ADL, in order to improve their quality of life.
ObjectiveTo investigate the relationship between lumbar facet joint degeneration of each segment and spine-pelvic sagittal balance parameters. MethodsA retrospective analysis was made the clinical data of 120 patients with lumbar degenerative disease, who accorded with the inclusion criteria between June and November 2014. There were 58 males and 62 females with an average age of 53 years (range, 24-77 years). The disease duration ranged from 3 to 96 months (mean, 6.6 months). Affected segments included L3, 4 in 32 cases, L4, 5 in 47 cases, and L5, S1 in 52 cases. The CT and X-ray films of the lumbar vertebrae were taken. The facet joint degeneration was graded based on the grading system of Pathria. The spine-pelvic sagittal balance parameters were measured, including lumbar lordosis (LL), upper lumbar lordosis (ULL), lower lumbar lordosis (LLL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS). According to normal range of PI, the patients were divided into 3 groups: group A (PI was 1ess than normal range), group B (PI was within normal range), and group C (PI was more than normal range). The facet joint degeneration was compared;according to the facet joint degeneration degree, the patients were divided into group N (mild degeneration group) and group M (serious degeneration group) to observe the relationship of lumbar facet joint degeneration of each segment and spine-pelvic sagittal balance parameters. ResultsAt L4, 5 and L5, S1, facet joint degeneration showed significant difference among groups A, B, and C (P<0.05), more serious facet joint degeneration was observed in group C;no significant difference was found in facet joint degeneration at L3, 4 (P>0.05). There was no significant difference in the other spine-pelvic sagittal balance parameters between groups N and M at each segment (P>0.05) except for PT (P<0.05). ConclusionPI of more than normal range may lead to or aggravate lumbar facet joint degeneration at L4, 5 and L5, S1;PT and PI are significantly associated with facet joint degeneration at the lower lumbar spine.
ObjectiveTo investigate the methods and effectiveness of one-stage operation for pelvis and acetabular fractures combined with Morel-Lavallée injury by internal fixation associated with vacuum sealing drainage (VSD). MethodsBetween June 2008 and October 2012, 15 cases of pelvis and acetabular fractures combined with Morel-Lavallée injury were treated. There were 5 males and 10 females, aged from 18 to 67 years (mean, 36.8 years). Fractures were caused by traffic accident in 11 cases and crashing injury of heavy object in 4 cases. The time from injury to hospitalization was 3 hours to 9 days (mean, 5.4 days). Morel-Lavallée injury located in the above posterior superior iliac spine in 4 cases, greater trochanter in 7 cases, and anterior proximal thigh in 4 cases. In 10 cases complicated by pelvic fracture, there were 1 case of anteroposterior compression type, 3 cases of lateral compression type, 5 cases of vertical shear type, and 1 case of compound injury type; in 5 cases complicated by acetabular fracture, there were 1 case of transverse fracture, 1 case of posterior wall and posterior column fracture, 1 case of transverse acetabulum plus posterior wall fracture, and 2 cases of both columns fracture. Open reduction and internal fixation were used to treat pelvic and acetabular fractures, and VSD to treat Morel-Lavallée injury. When the drainage volume was less than 20 mL/d, interrupted wound suture or free skin grafting was performed. ResultsThe hospitalization time was 16-31 days (mean, 20.8 days). Thirteen cases were followed up 4-16 months (mean, 7.8 months). The healing time of Morel-Lavallée injury was 16-36 days after operation (mean, 21.3 days). All the wounds had primary healing, and no infection occurred. The X-ray films showed that all fractures healed, with a mean healing time of 13.6 weeks (range, 11-18 weeks). At 6.5 months after operation, according to Majeed function scoring system in 8 cases of pelvic fracture, the results were excellent in 5 cases, good in 2 cases, and fair in 1 case; according to Harris hip scoring in 4 cases of acetabular fracture, the results were excellent in 2 cases, good in 1 case, and fair in 1 case. ConclusionTo pelvis-acetabular fractures combined with Morel-Lavallée injury, internal fixation treatment for fracture and VSD for Morel-Lavallée injury not only can cure merge Morel-Lavallée injury effectively, but also can guarantee the operation timing and incision safty of the pelvis-acetabular fractures.
ObjectiveTo study the effectiveness of a new anterolateral approach of distal femur in the treatment of type C distal femoral fractures by comparing with traditional lateral and anterolateral approaches. MethodsThe clinical data of 51 patients with type C distal femoral fractures treated between January 2008 and August 2011 were retrospectively analyzed. Of 51 patients, 24 patients received the new anterolateral approach of distal femur combined with fixation of condylar buttress plate (modified group), and 27 patients underwent traditional lateral or anterolateral approach combined with fixation of condylar buttress plate (traditional group). There was no significant difference in gender, age, injury cause, American Society of Anesthesiologist (ASA) classification, side, fracture type, complication, and the time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, hospitalization time, fracture healing time, and Hospital for Special Surgery (HSS) scores of the knee at 3, 6, and 12 months were recorded. ResultsThe operation was successfully completed and the incision healed by first intention in all patients. The operation time and frequency of intraoperative fluoroscopy of modified group were significantly less than those of traditional group (P<0.05). But the intraoperative blood loss and the hospitalization time showed no significant difference between 2 groups (P>0.05). All patients were followed up 12-37 months (mean, 21.3 months). X-ray films showed all fractures were union. The fracture healing time was (12.92±2.24) weeks in the modified group and (13.24±2.52) weeks in the traditional group, showing no significant difference (t=0.476, P=0.637). The knee HSS scores of modified group were significantly higher than those of traditional group at 3, 6, and 12 months after operation (P<0.05). There was no significant difference in the incidence of knee varus or valgus, leg length discrepancy, internal fixator loosening, flexing dysfunction of knee, traumatic arthritis of knee, and total complications between 2 groups (P>0.05). ConclusionComparing with traditional lateral and anterolateral approaches, using the new anterolateral approach to treat type C distal femoral fractures has the advantages of less damage to soft tissue, excellent exposure, less operation time, and frequency of intraoperative fluoroscopy, and better postoperative rehabilitation of knee joint.
ObjectiveTo explore the feasibility and effectiveness of unilateral pedicle screw rod and single poly (ether-ether-ketone) (PEEK) Cage for lumbar intervertebral disc protrusion. MethodsA total of 126 cases of single segment of lumbar intervertebral disc protrusion between January 2006 and June 2012 were divided into 2 groups in the randomized clinical trial. Unilateral pedicle screw fixation and single PEEK Cage was used in 63 cases (research group), and bilateral pedicle screw fixation and single PEEK Cage in 63 cases (control group). There was no significant difference in gender, age, disease duration, side, and affected segment between 2 groups (P>0.05). Schulte evaluation criterion was used to assess bone graft fusion, Oswestry disability index (ODI) to estimate the quality of life situation, and visual analogue scale (VAS) to evaluate the improvements of lower back pain. Macnab standards was applied to assess postoperative effectiveness, and Emery ways to measure the height of intervertebral space. ResultsThe incision length, operation time, intraoperative blood loss, hospitalization time, and hospitalization fee in research group were significantly less than those in control group (P<0.05). The patients were followed up 12-79 months (mean, 21.3 months) in research group, and 15-73 months (mean, 22.6 months) in control group. The postoperative lordosis was recovered well, and the height of intervertebral space was increased. No loosening or breakage of internal fixation occurred. The time of bone graft fusion was (6.8±1.3) months in research group and was (7.1±1.2) months in control group, showing no significant difference (t=1.153, P=0.110). The height of intervertebral space, ODI score, and VAS score were significantly improved when compared with preoperative ones in 2 groups (P<0.05), but no significant difference was found between 2 groups at preoperation and last follow-up (P>0.05). At 3 months after operation, postoperative effectiveness was assessed according to Macnab criterion, the excellent and good rate was 95.23% in research group (excellent in 13 cases, good in 47 cases, and fair in 3 cases) and was 71.42% in control group (excellent in 7 cases, good in 38 cases, fair in 15 cases, and poor in 3 cases); the research group was significantly superior to control group (χ2=6.110, P=0.006). ConclusionUnilateral pedicle screw fixation and single PEEK Cage has the advantages of small trauma, reliable fixation, shorter operation time, less bleeding, less economic cost, and early off-bed activity time. It can provide a simple and reliable choice in single segmental lumbar intervertebral disc protrusion.
