Case reports: splenic rupture after anterior thoracolumbar spinal fusion through a thoracoabdominal approach.

ABSTRACT: The anterior approach in spinal deformity surgery has increased in popularity in recent years. The thoracoabdominal approach to the thoracolumbar spine is associated with numerous possible complications, including injury to vital intraabdominal structures in close proximity to the area of exposure, such as the spleen. We describe the case of a 44-year-old woman who underwent an emergent exploratory laparotomy for progressive abdominal pain and hemodynamic instability that revealed splenic rupture two days after single-stage anterior spinal fusion with instrumentation for thoracolumbar kyphoscoliosis. Because the suspected etiology of the splenic hemorrhage was related to retraction, surgeons using the anterior approach should consider intermittent release of retractors and inspection of intraabdominal structures. Splenic rupture should be considered as part of the differential diagnosis for patients with hemodynamic instability after anterior approaches to the thoracolumbar spine.

Project description:BACKGROUND:While some traumatic closed index extensor tendon ruptures at the musclotendinous junction have been previously reported, closed index extensor tendon pseudorupture due to intertendinous attenuation is exceedingly rare with only one case report of a gymnastics-related sports injury in the English literature. Herein, we report two non-sports injury related cases of traumatic index extensor tendon attenuation mimicking closed tendon rupture, including the pathological findings and intraoperative video of the attenuated extensor indicis proprius tendon. CASE PRESENTATION:A 28-year-old man and a 30-year-old man caught their hands in a high-speed drill and lathe, respectively, which caused a sudden forced flexion of their wrists. They could not actively extend the metacarpophalangeal joints of their index fingers. Intraoperatively, although the extensor indicis proprius and index extensor digitorum communes tendons were in continuity without ruptures, both tendons were attenuated and stretched. The attenuated index extensor tendons were reconstructed either with shortening by plication or step-cut when the tendon damage was less severe or, in severely attenuated tendons, with tendon grafting (ipsilateral palmaris longus) or tendon transfer. Six months after the operation, the active extension of the index metacarpophalangeal joints had recovered well. CONCLUSIONS:Two cases of traumatic index extensor tendon attenuation were treated successfully by shortening the attenuated tendon in combination with tendon graft or transfer. We recommend WALANT (wide-awake local anesthesia and no tourniquet) in the reconstruction surgery of index extensor tendon attenuation to determine the appropriate amount of tendon shortening or optimal tension for tendon grafting or transfer. Intraoperative voluntary finger movement is essential, as it is otherwise difficult to judge the stretch length of intratendinous elongation and extent of traumatic intramuscular damage affecting tendon excursion.

Project description:IntroductionAdult spinal deformity (ASD) surgery patients are at higher risk for surgical site infections (SSIs) due to large incisions, high blood loss, long surgical duration, and extensive instrumentation. The use of vancomycin powder has demonstrated inconsistent results in ASD surgery. Antibiotic-impregnated calcium sulfate beads have been used in arthroplasty and foot and ankle surgery with promising results. The purpose of this study was to provide preliminary data on the use of vancomycin-impregnated calcium sulfate beads in the prevention of SSI following ASD surgery and provide comparisons to the use of vancomycin powder.MethodsA retrospective chart review was performed for 95 consecutive surgical ASD patients at a tertiary care center from January 2017 until March 2020. Patients received either vancomycin powder (powder group) or vancomycin-impregnated calcium sulfate beads (bead group) intrawound prior to closure. Patient demographics, operative course, and incidence of postoperative infections were recorded. A two-tailed chi-squared test was performed to compare infection rates.ResultsNinety-five patients were included for review. Forty-two patients were in the powder group and 53 patients were in the bead group. The bead group was older (59.8 vs 67.8 years, p < 0.01) with similar BMI and rates of diabetes, smoking, and length of surgery. There were four postoperative SSI in the powder group requiring operative irrigation and debridement and one SSI in the bead group (9.5% vs 1.9%, p = 0.09). All infections occurred in the first 90 days of the postoperative period.ConclusionPreliminary examination of the use of vancomycin-impregnated calcium sulfate beads demonstrated a 1.9% surgical site infection rate in adult spinal deformity surgical patients, which was not significantly different compared with the 9.5% infection rate in patients who received vancomycin powder. Prospective study is needed to determine if the differences found are significant in a larger number of patients.
