Transforaminal lumbar interbody fusion with a tantalum cage: lumbar lordosis redistribution and sacral slope restoration with a modified posterior technique.

Background: Transforaminal lumbar interbody fusion (TLIF), a commonly used procedure in spine surgery, has the advantage of a lower incidence of nerve lesions compared to the posterior lumbar interbody fusion (PLIF) technique. The intersomatic arthrodesis has always been carried out with a single tantalum cage normally used for PLIF. Tantalum is a metal that is particularly used in orthopedic surgery.

What Is the Role of Traction Test Radiographs in the Preoperative Planning of Adolescent Idiopathic Scoliosis?

Lower instrumented vertebra (LIV) selection is critical to avoid complications like adding-on. This study aims to determine the usefulness of the traction test (TR) in selecting the LIV during surgery for adolescent idiopathic scoliosis (AIS). We analyzed 42 AIS patients with Lenke 1 curves who had preoperative, postoperative, and at least 12-month follow-up X-rays, as well as preoperative side bending (SB) and TR radiograms.

Paraparesis and congenital severe hyperkyphosis in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome: A rare deformity management during the Sars-Cov-2 pandemic.

Introduction: Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) syndrome can be classified into two types: type I (isolated) without extragenital abnormalities; type II (associated) with the presence of extragenital dimorphisms. Skeletal abnormalities are the second most frequent extragenital manifestations.

Research Question: Association between MRKH and congenital scoliosis has been described; on the contrary, hyperkyphosis is very rare and sparsely described in the medical literature.
