To pool reliable evidences for the optimum anterior transposition technique in the treatment of cubital tunnel syndrome by comparing the clinical efficacy of subcutaneous and submuscular anterior ulnar nerve transposition.

Anterior Subcutaneous versus Submuscular Transposition of the Ulnar Nerve for Cubital Tunnel Syndrome: A Systematic Review and Meta-Analysis.

Subcutaneous and submuscular anterior ulnar nerve transposition have been widely used in patients with cubital tunnel syndrome. However, the reliable evidence in favor of 1 of 2 surgical options on clinical improvement remains controversial. To maximize the value of the available literature, we performed a systematic review and meta-analysis to compare subcutaneous versus submuscular anterior ulnar nerve transposition in patients with ulnar neuropathy at the elbow. PubMed, Cochrane Library, and EMBASE databases were searched for randomized and observational studies that compared subcutaneous transposition with submuscular transposition of ulnar nerve for cubital tunnel syndrome. The primary outcome was clinically relevant improvement in function compared to the baseline. Randomized and observational studies were separately analyzed with relative risks (RRs) and 95% confidence intervals (CIs). Two randomized controlled trials (RCTs) and 7 observational studies, involving 605 patients, were included. Our meta-analysis suggested that no significant differences in the primary outcomes were observed between comparison groups, both in RCT (RR, 1.16; 95% CI 0.68-1.98; P = 0.60; I2= 81%) and observational studies (RR, 1.01; 95% CI 0.95-1.08; P = 0.69; I2 = 0%). These findings were also consistent with all subgroup analyses for observational studies. In the secondary outcomes, the incidence of adverse events was significantly lower in subcutaneous group than in submuscular group (RR, 0.54; 95% CI 0.33-0.87; P = 0.01; I2 = 0%), whereas subcutaneous transposition failed to reveal more superiority than submuscular transposition in static two-point discrimination (MD, 0.04; 95% CI -0.18-0.25; P = 0.74; I = 0%). The available evidence is not adequately powered to identify the best anterior ulnar nerve transposition technique for cubital tunnel syndrome on the basis of clinical outcomes, that is, suggests that subcutaneous and submuscular anterior transposition might be equally effective in terms of postoperative clinical improvement. However, differences in clinical outcomes metrics should be noted, and these findings largely rely on the outcomes data from observational studies that are potentially subject to a high risk of selection bias. Therefore, more high-quality and adequately powered RCTs with standardized clinical outcomes metrics are necessary for proper comparison of these techniques.

Few studies have used fine-needle aspiration cytology for the purpose of isolated skeletal Rosai-Dorfman diseases (RDDs) diagnosis.Herein, we described an extremely rare case of a 56-year-old woman who presented to our hospital with an insidious onset of pain in the right proximal tibia.The provisional cytologic diagnosis of RDDs was confirmed by a computer tomography-guided core needle biopsy of the lesion. Subsequently, curettage and autogenous iliac crest bone graft were performed successfully. At the 4th year of follow-up her clinical symptoms disappeared, and there was no clinical evidence of lesion recurrence.Our case highlighted the role of fine-needle aspiration cytology with immunohistochemical studies in the diagnosis of RDDs and the characteristic features of isolated skeletal RDDs in an unusual location, the knowledge of which would help avoid missed or delayed diagnosis in the future.

Multiple surgical modalities have been developedl and applied for surgical excision of spinal dumbbell tumors. The microscopic minimally invasive keyhole technique has not yet been well characterized for this purpose. We report our experience with 1-stage surgical resection of both intraforaminal and extraforaminal/paraspinal components of spinal dumbbell tumors using the microsurgical keyhole technique.

Microscopic Minimally Invasive Keyhole Technique for Surgical Resection of Spinal Dumbbell Tumors.

The aim of this study was to evaluate the safety and efficacy of the microscopic minimally invasive keyhole technique for surgical resection of thoracic spinal meningiomas.

Microscopic Keyhole Technique for Surgical Removal of Thoracic Spinal Meningiomas.

Intraspinal gout tophus in the lumbar vertebral canal associated with gouty arthritis is rare. We present 2 cases with the first manifestations of a sequestrated intervertebral disc and an extradural tumor, and histopathologically proven to be gouty deposits in the lumbar vertebral canal.

Multiple surgical approaches have been studied and accepted for the removal of highly downward migrated lumbar disc herniation (LDH). Here, we investigated the efficacy and safety of full-endoscopic foraminoplasty for highly downward migrated LDH.

Full-endoscopic foraminoplasty for highly down-migrated lumbar disc herniation.

Endoscopic transforaminal lumbar interbody fusion (endo-TLIF) with bilateral percutaneous pedicle screw fixation is an emerging option for low-grade spondylolisthesis. However, uniportal full endo-TLIF with a complete reduction for high-grade spondylolisthesis is challenging.
