STUDY DESIGN: This is a systematic review and meta-analysis. OBJECTIVE: To examine the differences in outcomes among current constructs and techniques for anterior cervical corpectomy and fusion (ACCF) in patients with single or multiple level cervical myelopathy (CM) secondary to cervical spondylosis or ossified posterior longitudinal ligament. SUMMARY OF BACKGROUND DATA: The natural history of CM can be a progressive disease process. In such cases, where surgical decompression is indicated to halt the progression, ACCF is typically chosen for pathology located posterior to the vertebral body...

Acute idiopathic sudden sensorineural hearing loss (ISSNHL) following lumbar spinal surgery is an exceedingly rare phenomenon. This paper presents a case of ISSNHL presenting acutely after lumbar spine decompression and fusion treated with transtympanic steroids and hyperbaric oxygen (HBO₂) therapy. It also presents the ironic case of SSNHL secondary to presumed viral pathology sustained by the patient's operative surgeon who was treated with transtympanic steroids and HBO₂ as well. Proposed etiologies of the patient's ISSNHL include: hypotension, prone operative position, malfitted/malpositioned headrest, microemboli from a cell-saver, and nitrous oxide anesthesia...

BACKGROUND: Osteochondral lesions of the medial talus (OLT) frequently lead to chronic ankle pain and osteoarthritis. Arthroscopic debridement, subchondral bone stimulation by drilling, and microfracturing are options for primary therapy in small lesions. In larger lesions, restoration of the talar dome contour seems to be a mandatory course of action. METHODS: In a case series, we followed up four patients being treated with a focal resurfacing prosthetic due to large osteochondral talar lesions...

BACKGROUND: When treatment of acute septic arthritis of the hip is delayed, severe sequelae can occur. This may take the form of coxa breva, vara, or valga. Pseudoarthrosis of the femoral neck is a rare complication with only a few studies to guide treatment. QUESTION/PURPOSES: In a small series of patients with pseudarthrosis of the femoral neck after acute septic arthritis, we wanted to determine (1) whether femoral neck union can be achieved using a variety of surgical approaches; (2) whether these patients satisfied criteria outlined by Hunka and Choi, defined as a stable hip, a flexion arc ≥ 70° and no fixed adduction or abduction contractures, fixed flexion deformity not more than 20°, pain relief, and restoration of activities of daily living after surgery; and (3) any treatment-related complications if observed...

Spinal fusion is a common surgical procedure to address a range of spinal pathologies, like damaged or degenerated discs. After the removal of the intervertebral disc (IVD), a structural spacer is positioned followed by internal fixation, and fusion of the degenerated segment by natural bone growth. Due to their osteoinductive properties, bone morphogenetic proteins (BMP) are applied to promote spinal fusion. Although spinal fusion is successful in most patients, the rates of non-unions after lumbar spine fusion range from 5% to 35%...

Objectives: Lumbosacral fusion through either an anterior or a posterior approach to achieve good lordosis and stability is always a challenging surgical operation and is often accompanied by a higher rate of pseudarthrosis than when other lumbar segments are involved. This study evaluated the clinical and radiological results of lumbosacral fusions achieved through a combined anterior and posterior approach. Materials and Methods: From June 2008 to 2012, 20 patients who had L5-S1 instability and stenosis were consecutively treated, first by anterior interbody fusion using an allogenous strut bone graft through the pararectus approach and then by posterior pedicle screw fixation...

Surgical site infections after posterior spinal surgery may lead to spondylodiscitis, pseudarthrosis, correction loss, adverse neurological sequelae, sepsis, and poor outcomes if not treated immediately. Infection rates vary depending on the type and extent of operative procedures, use of instrumentation, and patients' risk factors. Image evaluation is crucial for early diagnosis and should be complementary to clinical routes, laboratory survey, and treatment timing. Magnetic resonance imaging detects early inflammatory infiltration into the vertebrae and soft tissues, including hyperemic changes of edematous marrow, vertebral endplate, and abscess or phlegmon accumulation around the intervertebral disk, epidural, and paravertebral spaces...

Surgical site infection (SSI) following spine surgery can be devastating for both the patient and the surgeon. It leads to significant morbidity and associated health care costs, from readmissions, reoperations, and subsequent poor clinical outcomes. Complications associated with SSI following spine surgery include pseudarthrosis, neurological deterioration, sepsis, and death. Its management can be very challenging. The diagnosis of SSI involves the interpretation of combined clinical, laboratory, and occasionally radiologic findings...

BACKGROUND: Surgical correction of ASD can be challenging. The indication for surgery is individual and after specification of the therapeutic goals, detailed planning of the surgery is essential to achieve a good postoperative result. COMPLICATIONS AND INDICATION: The reasons for the comparatively high complication rate are well investigated and are often located at the lumbosacral junction. In addition to negative general factors like osteoporosis, especially undercorrection of the sagittal profile and insufficient lumbo-pelvic stabilization are causative...

Introduction Oblique lumbar interbody fusion (OLIF) is a newer procedure that avoids the psoas and lumbosacral plexus due to its oblique trajectory into the retroperitoneal space. While early experience with OLIF is reassuring, the longer-term clinical efficacy has not been well established. The purpose of this study was to describe two-year clinical outcomes with OLIF performed by a single surgeon during the learning curve without the aid of the neuromonitoring. Materials and methods Chart review was performed for the consecutive patients who underwent OLIF by a single surgeon...
