Minimally invasive treatment for idiopathic chondrolysis of the hip: analysis of forty-one cases.

Purpose: Idiopathic chondrolysis of the hip is characterized by the loss of the articular cartilage of the hip joint with spectrum ranging from full recovery to fibrous ankylosis. Study assessed outcomes following intra-articular steroid injections, joint manipulation and traction immobilization.

Methods: Retrospective (2012-2021) review of 41 cases treated for idiopathic chondrolysis of hip, assessed pre-operatively and post-operatively (minimum 2-year follow-up) using Children's Hospital Oakland Hip Evaluation Score (CHOHES), visual analogue scale (VAS) and range of motion measurements.

"Critical pedicle wall" breaches analysis in complex spinal deformity using O-arm navigation.

Background: Free-hand and fluoroscopic-guided pedicle screw placement has been associated with higher rates of pedicle breaches (frequency range 15-40% especially in deformed pedicles). Neurological complications are more "critical" (i.e.

Efficacy and Safety of Stempeucel in Osteoarthritis of the Knee: A Phase 3 Randomized, Double-Blind, Multicenter, Placebo-Controlled Study.

Background: Osteoarthritis is a chronic, progressive, and degenerative condition with limited therapy options. Recently, biologic therapies have been an evolving option for the management of osteoarthritis.

Purpose: To assess whether allogenic mesenchymal stromal cells (MSCs) have the potential to improve functional parameters and induce cartilage regeneration in patients with osteoarthritis.

Chronic Intramedullary Spinal Cord Abscess Mimicking Intramedullary Spinal Cord Tumor-"Phantom Tumor": A Case Report.

Case: A 33-year-old woman with back pain and radiculopathy had presented with bilateral ankle weakness. MRI showed an intramedullary conus lesion suggestive of neoplasm, but posterior midline durotomy revealed only pus. Pus samples showed Staphylococcus aureus, which was treated with 6 weeks of antibiotics.

Efficacy of less Invasive modified O-arm navigated delta fixation in osteoporotic high-grade spondylolisthesis: "a LIMO delta technique".

Purpose: In 1994, the technique of transdiscal screws fixation in spondylolisthesis was introduced but did not gained popularity as it failed to address problems with spinal sagittal imbalance, retroverted pelvis, pseudoarthrosis, implant failure and neural injury. Majority of problems were due to lack of clear indications; hence, in this study, with modification of traditional technique and use of O-arm navigation for selected group of patients, we have addressed the above problems and given good to excellent functional outcomes.

Methods: We did prospective study on 15 patients with osteoporotic high-grade spondylolisthesis Meyerding grade 3 & 4 admitted in period 2020-2021.

Correlation between Preoperative Magnetic Resonance Imaging Signal Intensity Changes and Clinical Outcomes in Patients Surgically Treated for Cervical Myeloradiculopathy.

Study Design: This was a single surgeon, single center-based retrospective study with prospective data collection.

Purpose: To assess the correlation between T2-weighted magnetic resonance imaging (MRI) signal intensity (SI) changes and factors such as age, duration of symptoms, baseline modified Japanese Orthopedic Association (mJOA) score and to determine its prognostic value in predicting recovery after surgery.

Overview Of Literature: Whether intramedullary cord T2-weighted MRI SI changes can predict operative outcomes of cervical myeloradiculopathy remains debatable, with only a few prospective studies analyzing the same.

Extraosseous thoracic foraminal osteoblastoma: diagnostic dilemma and management with 3 year follow-up.

Osteoblastomas are bone forming lesions arising mainly from posterior elements of the vertebra. They are commonly encountered in the cervical and lumbar regions. We present a case of a thoracic osteoblastoma which is extra osseous and is not communicating with any part of the vertebra present intraforaminally.
