Postoperative Infections of the Lumbar Spine: Presentation and Management

Abstract

: Postoperative infections of the lumbar spine pose significant challenges in clinical management and patient outcomes. Despite advances in surgical techniques and perioperative care, these infections continue to occur, leading to increased morbidity and healthcare costs. Understanding the presentation and management of these infections is crucial for optimizing patient care and outcomes. The objective of the study is to assess the prevalence of spinal surgeries, comorbidities, diagnostic modalities, treatment approaches, and their correlations in managing surgical site infections among patients at Khyber Teaching Hospital. Medical records of 800 patients who underwent lumbar spine surgery at Khyber Teaching Hospital from 2020 to 2022 were retrospectively reviewed. Data regarding patient demographics, surgical details, infection characteristics, microbiological findings, treatment modalities, and outcomes were collected and analyzed. Descriptive statistics were used to summarize the findings, and inferential statistics were employed to explore associations between variables. The study comprised 800 spinal surgery patients at Khyber Teaching Hospital, with a mean age of 58 ± (12.3 SD) years. Laminectomy was the most common procedure (43.75%), followed by discectomy (22.5%). Clinical inspection was predominantly used for SSI diagnosis (95.6%), and post-surgical measures included debridement, antibiotics and cultures. Correlation analysis revealed varying associations between surgeries and post-operative symptoms. The Treatment outcomes showed high-resolution rates, with surgical debridement demonstrating the highest efficacy. This study reveals laminectomy as the most common procedure. As laminectomy was the most common procedure done, that’s why SSI was more common in these procedures. Key diagnostic methods for detecting surgical site infections (SSI) was clinical examination of wound status and pus discharge. The study revealed that patients with early surgical debridement had the best outcome in early resolution of infection and wound healing. Thus, Correlation analysis between surgeries and symptoms guides clinical decisions, with surgical debridement followed by antibiotics showing the highest efficacy in resolving infections. These findings stress the need for tailored patient care strategies to enhance outcomes and reduce complications in spinal surgery.
