Biomechanical assessment of proximal junctional semi-rigid fixation in long-segment thoracolumbar constructs.

Authors:

J Neurosurg Spine 2018 Oct 1:1-9. Epub 2018 Oct 1.

OBJECTIVEProximal junctional kyphosis (PJK) and failure (PJF) are potentially catastrophic complications that result from abrupt changes in stress across rigid instrumented and mobile non-fused segments of the spine (transition zone) after adult spinal deformity surgery. Recently, data have indicated that extension (widening) of the transitional zone via use of proximal junctional (PJ) semi-rigid fixation can mitigate this complication. To assess the biomechanical effectiveness of 3 semi-rigid fixation constructs (compared to pedicle screw fixation alone), the authors performed cadaveric studies that measured the extent of PJ motion and intradiscal pressure changes (ΔIDP).

Although imaging features can be confusing, an awareness of this condition and careful image interpretation by radiologists could facilitate early recognition and management of a torted lobe.

[Torsion of wandering spleen - unusual cause to acute abdominal pain in pediatric patients].

Lakartidningen 2018 Nov 20;115. Epub 2018 Nov 20.

Wandering spleen is a rare reason for acute abdominal pain in pediatric patients caused by laxity of the splenic ligaments. It can be complicated by torsion of the pedicle, leading to ischemia, a situation that in most cases results in acute abdominal surgery. To prevent ischemia of a mobile spleen caused by a total occlusion of the pedicle, splenopexy can be considered. Read More

Surgical treatment of trigeminal neuralgia with no neurovascular compression: A retrospective study and literature review.

J Clin Neurosci 2018 Dec 24;58:42-48. Epub 2018 Oct 24.

Department of Skull Base Surgery Center, Department of Neurosurgery, XuanWu Hospital, Capital Medical University, Beijing, China.

The objective of the current study is to summarize the experiences of 360-degree circumferential arachnoid dissection for TN in patients without NVC. Clinical data from 19 TN patients without NVC who underwent 360-degree circumferential arachnoid dissection were retrospectively analyzed. All patients underwent preoperative examinations of three-dimensional time-of-flight magnetic resonance angiography (3D-TOF-MRA) and three-dimensional nuclear magnetic resonance of constructive interference in steady state (3D-CISS) to identify the neurovascular structures around the trigeminal nerve.

Predictive value of hematological parameters in testicular torsion: retrospective investigation of data from a high-volume tertiary care center.

J Int Med Res 2018 Nov 19:300060518809778. Epub 2018 Nov 19.

Department of Urology, Tepecik Training and Research Hospital, Izmir, Turkey.

Objective: To investigate the use of hematological parameters in the differential diagnosis of testis torsion and epididymo-orchitis, and to determine the predictive value of these parameters in the diagnosis of testis torsion.

Methods: This study retrospectively reviewed the medical data of patients who presented to our institute with the complaint of acute scrotal pain. Eighty-five patients who had undergone orchiectomy or surgical detorsion due to testis torsion and 72 patients with epididymo-orchitis were included in the study. Read More

Rare documented case report of a retroperitoneal hernia as a complication to an anterior retroperitoneal spinal exposure.

Int J Surg Case Rep 2018 Oct 29;53:309-311. Epub 2018 Oct 29.

Sky Ridge Medical Center, Office of Graduate Medical Education, 10101 RidgeGate Pkwy, Lone Tree, CO, 80124, United States. Electronic address:

Introduction: Anterior retroperitoneal spinal exposures are widely used today for spinal surgeries. Incisional hernias are a documented complication of anterior spine exposures; however, there are no documented cases of hernias into the dissected retroperitoneal space. We presented this exceptionally rare patient's complication to underscores the critical importance of preserving the peritoneum as a biologic barrier during retroperitoneal spine exposures.

Retrograde Stainless Steel Flexible Nails Have Superior Resistance to Bending in Distal Third Femoral Shaft Fractures.

J Pediatr Orthop 2018 Nov 16. Epub 2018 Nov 16.

Texas Scottish Rite Hospital for Children, Dallas, TX.

Background: It has been shown that retrograde titanium flexible intramedullary nails (Ti FIN) provide superior resistance to bending compared to antegrade Ti FIN in distal femur fractures. The purpose of this study was to compare resistance to torsional and bending forces of stainless steel (SS) FIN, with or without a locking screw, and Ti FIN in distal third femoral shaft fractures. We hypothesize that locked retrograde SS FIN will demonstrate greater resistance to both bending and torsional forces. Read More
