Functional outcome of surgical management of low mid-grade lumbar spondylolisthesis when considering the sagittal balance parameters preoperatively: a prospective study.

Background: Prospective study objectives. A sagittal balance is a good tool to improve the functional outcome of spine spondylolisthesis surgeries, primarily noted that it has a good impact in deformity surgery and then applied to every spine surgery and the aim of this study is to evaluate its functional outcome when considered in preoperative planning for non-dysplastic low- and mid-grade spondylolisthesis surgeries.

Method: Forty patients diagnosed as low- or mid-grade non-dysplastic spondylolisthesis had undergone surgery at Cairo University after failed medical treatment had been evaluated preoperatively by measuring the sagittal balance parameters which include SVA, spinopelvic angles, lumbar lordosis, pelvic tilt, sacral slope, and pelvic incidence and then measure it along a follow-up period of 1 year postoperatively started from February 2018 and correlate it with functional outcome using Oswestry score (ODI)and VAS.

Neurosurgical Wrong Surgical Site in Lower-Middle- or Low-Income Countries (LMICs): A Survey Study.

Background: One of the most preventable errors of a surgeon's career is operating on the incorrect surgical site (ICSS). No study in any specialty has ever investigated the incidence of ICSS events in lower-income countries. This study focuses on identifying the occurrence of these events along with an analysis of potential causes leading to these unfortunate events.

Arthroscopic Superior Capsular Reconstruction for Management of Massive Irreparable Rotator Cuff Tears: A Simple Alternative Technique.

The use of acellular dermal allograft in arthroscopic superior capsular reconstruction is a promising treatment option for massive irreparable rotator cuff tears. However, indications are limited to a subset of patients, so it is not routinely performed. Therefore, the surgery is technically demanding, although it has evolved in recent years.

Identification of IL-27 as potent regulator of inflammatory osteolysis associated with vitamin E-blended ultra-high molecular weight polyethylene debris of orthopedic implants.

Vitamin E-blended ultra-high molecular weight polyethylene (VE-UHMWPE) is a newly introduced material for prosthetic components that has proven a better mechanical performance with lesser adverse cellular responses than conventional polyethylene in experimental animal models. However, the mechanisms by which VE-UHMWPE particles trigger a reduced osteolytic activity are unclear and remain to be investigated. Therefore, the current study aims at exploring a possible anti-osteolytic mechanism associated with VE-UHMWPE particles.

A Novel Bone Marrow Stimulation Technique Augmented by Administration of Ultrapurified Alginate Gel Enhances Osteochondral Repair in a Rabbit Model.

Cartilage injuries are a common health problem resulting in the loss of daily activities. Bone marrow stimulation technique, one of the surgical techniques for the cartilage injuries, is characterized by technical simplicity and less invasiveness. However, it has been shown to result in fibrous or fibrocartilaginous repair with inferior long-term results.
