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.

Does Risser Casting for Adolescent Idiopathic Scoliosis Still Have a Role in the Treatment of Curves Larger Than 40°? A Case Control Study with Bracing.

Background: The most common conservative treatment for Adolescent Idiopathic Scoliosis (AIS) is bracing. However, several papers questioned the effectiveness of bracing for curves between 40° and 50° Cobb: the effectiveness in preventing curve progression could be as low as 35%. Seriate casting is considered a standard approach in early onset scoliosis; however, in the setting of AIS, cast treatment is seldom utilized, with only few studies reporting on its effectiveness.

Apical vertebral derotation and translation (AVDT) for adolescent idiopathic scoliosis using screws and sublaminar bands: a safer concept for deformity correction.

Purpose: To assess the efficacy and safety of a new deformity correction philosophy treatment for AIS called apical vertebral derotation and translation (AVDT).

Methods: It is a retrospective study of prospectively collected data concerning two different scoliosis correction techniques used in our department. A total of 81 patients (22M, 59F) with a mean age of 15.

Monosegmental vs bisegmental pedicle fixation for the treatment of thoracolumbar spine fractures.

Introduction: The anatomy and biomechanics of the thoracolumbar spine place these segments at high risk of trauma injuries. Treatment options are either conservative or surgical, and there is a lack of consensus about the right indications. International scientific publications agree only on basic surgical principles: vertebral stability, deformity correction, protection of neurological structures and fast functional recovery.

Complication rate in adult deformity surgical treatment: safety of the posterior osteotomies.

Purpose: The treatment of adult scoliosis is a challenge especially in patients over 50 years old with severe, rigid curves in whom the use of vertebral osteotomies may be necessary to correct the deformity. The aim the study was to analyse the perioperative complications related to vertebral osteotomies in elderly treated for spinal deformity.

Methods: We analysed 72 consecutive cases of kyphoscoliosis, we classify them according to Berjano-Lamartina classification.

A randomized double-blind clinical trial on the treatment of knee osteoarthritis: the efficacy of polynucleotides compared to standard hyaluronian viscosupplementation.

Background: This randomized, double-blind, parallel-group clinical trial aims to assess the equivalence of intra-articular polynucleotides compared to standard hyaluronic acid (HA) viscosupplementation in the treatment of knee osteoarthritis (OA).

Methods: 75 patients affected by knee OA were assessed for eligibility and 72 were enrolled and randomized to receive either intra-articular polynucleotides (Condrotide-36 patients) or hyaluronic acid (Hyalubrix-36 patients) at the Orthopedic Institute "Gaetano Pini" (Milan). All patients underwent three intra-articular injections of Condrotide or Hyalubrix with an interval of 1week.
