More help than harm: surgery for metastatic spinal cord compression is associated with more favorable overall survival within a propensity score analysis.

Purpose: Indication for surgical decompression in metastatic spinal cord compression (MSCC) is often based on prognostic scores such as the modified Bauer score (mBs), with favorable prognosis suggestive of surgery and poor prognosis of non-surgical management. This study aimed to clarify if (1) surgery may directly affect overall survival (OS) aside from short-term neurologic outcome, (2) explore whether selected patient subgroups with poor mBs might still benefit from surgery, and (3) gauge putative adverse effects of surgery on short-term oncologic outcomes.

Methods: Single-center propensity score analyses with inverse-probability-of-treatment-weights (IPTW) of OS and short-term neurologic outcomes in MSCC patients treated with or without surgery between 2007 and 2020.

Spinal Surgery Site Infection Leading to Implant Loosening Is Influenced by the Number of Prior Operations.

Study Design: Retrospective Cohort Study.

Objectives: Spinal surgery site infection and chronic implant infection are possible causes for ongoing pain, implant loosening, and failed back surgery syndrome. Evidence of chronic infection was found in 29.

Risk adapted diagnostics and hospitalization following mild traumatic brain injury.

Introduction: Traumatic brain injury (TBI) remains a leading cause of hospital admission and mortality, intracranial hemorrhage (ICH) presents a severe complication. Low complication tolerance in developed countries and risk uncertainty, often cause excessive observation, diagnostics and hospitalization, considered unnecessary and expensive. Risk factors predicting ICH, progression and death in patients hospitalized with mild TBI have not been identified yet.

A novel method of clinical first tarsometatarsal joint hypermobility testing and radiologic verification.

Background: First tarsometatarsal joint (TMT-1) hypermobility might cause hallux valgus deformity (HV), and recurrence following surgical correction. Anatomic findings, indicating tibialis anterior tendon (TAT) involvement in TMT‑1 stabilization, led to the development of cross-glide test allowing clinical TMT‑1 stability testing. Cross-glide test function was evaluated in anatomical specimens and in the clinical setting, compared to simulated weight-bearing computer tomography (CT) analysis.

Langerhans-cell histiocytosis of the cervical spine in an adult patient: Case report and review of the literature.

Langerhans-cell histiocytosis (LCH) is a rare, benign bone tumor, usually occurring in children and younger adults under 20 years old. Only a few cases of solitary bone lesions of the adult spine are reported in literature, therapeutic guidelines or treatment regimens for lesions of the adult spine are not established yet to our knowledge.

Cadaveric-biomechanical evaluation of bone-implant construct of proximal humerus fractures (Neer type 3).

Background: A biomechanical cadaver study was performed to test the stability and strength of screw osteosynthesis of surgical neck fractures of the humerus.

Methods: After bone density measurement, 64 cadaver proximal humerus bones were bent to create a subcapital fracture. The fracture was then stabilized by means of screw osteosynthesis randomly assigned to subgroups of screw positioning, size of screw, and stress test (torsion/bending).
