Comparison of the Clinical Outcomes of Full-Endoscopic Visualized Foraminoplasty and Discectomy Versus Microdiscectomy for Lumbar Disc Herniation.

Based on each patient's TGCT preoperative imaging and intraoperative examination, three types and four subtypes of knee TGCT were identified and classified: Type 1: localized TGCT, Subtype 1a: localized intra-articular TGCT (A), Subtype 1b: localized extra-articular TGCT (B). Type 2: diffuse TGCT, Subtype 2a: diffuse intra-articular TGCT with bone normal (C), Subtype 2b: diffuse intra-articular TGCT with bone destruction (D), Type 3: diffuse TGCT across the knee joint capsule (E). Arthroscopic tumor resection is recommended for TGCT with Subtype 1a, while direct tumor resection is recommended for TGCT with Subtype 1b. The TGCT with Subtypes 2a and 2b should be completely removed while TKA is recommended for some patients with severe bone destruction in Subtypes 2b. Neoadjuvant or adjuvant therapies should be recommended for TGCT with Type 3.

Blood tests and joint aspiration used as tools for the preoperative diagnosis of periprosthetic joint infection (PJI). Although these tests show good diagnostic value. Joint aspiration as an invasive procedure may increase the risk of deep infections and often fails to aspirate joint fluid. Thus, there is a need to get more accurate information on blood tests to diagnose PJI. This study included the full range of serological inflammation-related markers, based on the prediction model, multiple combinations analyzed, and the best combinations of serum markers selected.

This study aimed to evaluate the treatment effects of the reinforced Ma–Griffith method combined with a minimally invasive small incision in the treatment of acute Achilles tendon rupture. I: Summary of patients' preoperative status. II: Reinforced Ma–Griffith method combined with a minimally invasive small-incision technique. III: Summary of patients' postoperative recovery status (AOFAS and ATRS).

Although the occurrence and distribution of neurovascular structures within the CPM is complex and varies greatly, it can provide a potential cavity for visualization during LLIF. Using psoas major as a reference, this novel grid system can be used to identify the CPM beneath the psoas muscle and thus identify a safe entry point for surgery.

ACAF can decompress the entrance zone of intervertebral foramina effectively, which provides more space for nerve roots to pass through the narrowest part of the intervertebral foramina. Cadaveric and Radiographic measurements indicated the decompression width in ACAF surgery included the origins and massive running part of bilateral ventral rootlets in the spinal canal.

Spinal surgeons and researchers should be aware of the effects of variation in numbers of thoracic vertebrae and lumbar vertebrae on global spinal parameters and sagittal balance.

The common reasons for failed primary surgery in CS patients with SHV undergoing posterior spinal fusion were severe post-operative curve progression of focal scoliosis, implant failure and trunk imbalance. The revision strategies including resection of residual hemivertebra, extended fusion levels, complete pseudarthrosis resection, replacement of fixation and horizontalization of UIV/LIV.

In the study, we describe the surgical technique of cervical transdural discectomy with laminoplasty for the treatment of multi-segment cervical spinal stenosis accompanied with cervical disc herniation and investigate its surgical outcomes and complications in 31 patients. We found that cervical transdural discectomy with laminoplasty technique could acquire satisfactory surgical outcomes for those patients, but the surgical indications of the patients need to be selected strictly.
