Abstract

Objectives: We investigated the relationship between the perioperative nutritional status and postoperative walking ability in patients with hip fractures. Methods: We included 246 surgically treated elderly patients with hip fractures who were ambulatory before the injury. Patients were divided into two groups: group A, who were able to walk at discharge, and group B, who were unable to walk at discharge. We pair-matched these two groups according to age, preoperative subdivided walking ability, and fracture site to form groups A′ and B'. The prognostic nutritional index (PNI; PNI = 10 × serum albumin (g/dL) + 0.005 × blood total lymphocyte count (/mm³)) before surgery and 1 day, 1 week, and 2 weeks after surgery and energy intake 1 and 2 weeks after surgery were compared. Results: After adjustments for age, preoperative subdivided walking ability, and fracture site, there were 51 patients in group A' (mean age 84.6 years) and 51 patients in group B' (mean age 84.7 years). In group A'/group B′, PNI was 43.38/42.60 (P = 0.19) before surgery, 33.87/33.31 (P = 0.44) 1 day after surgery, 34.99/32.35 (P = 0.01) 1 week after surgery, and 37.33/35.69 (P = 0.15) 2 weeks after surgery. Energy intake was 1380.8/1203.1 kcal (P = 0.01) 1 week after surgery and 1382.0/1335.6 kcal (P = 0.60) 2 weeks after surgery. Conclusions: PNI and energy intake at 1 week postoperatively were associated with early postoperative nutrition and the recovery of walking ability.

Abstract

Background: Since 1929, only 171 epidural hemangioma cases have been reported. We report five epidural hemangiomas and review cases reported over the past decade in terms of radiological features and clinical findings. Methods: Among patients operated on for spinal tumors at our hospital between 2009 and 2020, five had epidural hemangiomas. We retrospectively examined patient records and images and reviewed relevant English literature in PubMed from 2009 to 2019. Eighty-seven epidural hemangioma cases were reported in the last 10 years. Results: Among 87 cases, the average age was 49.58 years; 43 and 44 cases were male and female, respectively. The most common lesion level was thoracic (59.8%), while common symptoms were back pain (42.5%); numbness, hypoesthesia, or anesthesia (37.9%); paraparesis (34.5%); and radicular pain (20.7%). On magnetic resonance imaging (MRI), 77.1% showed hypo-isointensity on T1-weighted image (WI), hyperintensity on T2WI, and homogenous enhanced patterns with contrast. Total resection was performed in most cases, with good clinical outcomes. Preoperative embolization was performed in four cases, with good surgical outcomes. The median follow-up duration of postoperative MRI was 16 months, and no case had recurrence. Conclusions: Epidural hemangiomas are extremely rare and may be difficult to diagnose preoperatively. They should be considered if a dumbbell-shaped or epidural hypervascular lesion is noted. The treatment of choice for epidural hemangioma is total resection, with most cases having good clinical outcomes. Preoperative embolization may be useful for reducing bleeding. Although there were almost no recurrences after resection, careful follow-up for longer periods is required.

Abstract

Study Design: Retrospective multicenter study. Objective: Posterior decompression surgery for cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) is a common surgery; however, it can cause postoperative cervical deformity (CD). The purpose of this study was to investigate the risk factors for CD. Methods: The participants were 193 patients underwent laminoplasty or laminectomy for CSM or OPLL. CD was defined as a C2-7 sagittal vertical axis (SVA) ≥ 40 mm or a cervical lordosis angle (CL) ≤ −10°. The participants were divided into 2 groups: NCD (without CD before surgery), CD (with CD before surgery). NCD group was divided based on the presence of CD 1 year after surgery as follows: postoperative CD (PCD) and no PCD (NPCD). Results: There were 153 patients (NCD), 40 (CD), 126 (NPCD), and 27 (PCD). There was significant difference in the number of decompressed lamina (NPCD: PCD = 4.1:4.5), the presence of C2 decompression (2: 11%), and C5 palsy (0: 11%). The risk factors for onset of CD, PCD, and CL ≤ −10° as assessed by multiple logistic regression analysis were preoperative C2-7 SVA ≥ 30 mm (odds ratio [OR]: 19.0), decompression of C2 or C7 lamina (OR 3.1), and preoperative CL ≤ 2° (OR 42.0), respectively. Conclusions: To prevent postoperative CD, it is important to avoid decompression of the C2 or C7 lamina. Moreover, in case with C2-7 SVA ≥ 30 mm or CL ≤ 2° before surgery, it is important to explain the risks and consider adding fusion surgery.
