Endoscopic spine surgery
Endoscopic spine surgery is a minimally invasive procedure used to treat severe back pain caused by slipped discs, spinal stenosis, or scoliosis when conventional treatments like medication and physical therapy have failed. The surgeon makes a small incision and inserts specialized tools including an endoscope to view and repair the damaged spinal area. Benefits include quicker recovery, shorter hospital stays, less pain and blood loss, and lower risk of complications compared to open spine surgery.

THR
Total hip replacement (THR) is a common procedure to treat arthritis of the hip. Prof. John Charnley pioneered THR in the 1960s using low-friction arthroplasty with polyethylene and acrylic bone cement. THR aims to reduce joint reaction forces by recentering the femoral head and lengthening muscle lever arms. Surgeons select implants and fixation methods based on patient factors and bone quality. Outcomes depend on restoring normal hip biomechanics and long-term implant fixation to bone.

This document provides information on revision total hip arthroplasty (THA). It discusses indications such as painful loosening or fracture of implant components. Preoperative planning involves high-quality imaging to identify implant type and deficiencies. Complex revisions require additional equipment for tasks like cement and implant removal. The posterolateral surgical approach provides best exposure. Deficiencies of the acetabulum and femur are reconstructed using bone grafts, augments, and special implants to restore joint mechanics and implant fixation. Massive defects may require proximal femoral allografts or modular replacements.

There are many different types of conditions that cause back pain. Like most medical conditions, back pain is treatable through several methodologies. Determining what condition you have is the key to determining the right treatment option for you. Back pain comes in many forms, lower back pain, middle back pain, and upper back pain are just a few of the symptoms associated with spinalconditions. You may also have pain or tingling in your extremities that may be indications of spinal conditions. Feel free to browse through our articles about conditions. Contact your doctor to set up an appointment to start your road to recovery.
Every person is different, so symptoms of conditions may present
differently for different people. Symptoms also vary depending on the
condition, its severity, location, and other factors.

intramedullary nailing
This document provides an overview of intramedullary nailing principles. It discusses the history and evolution of intramedullary nails from wooden sticks and ivory pegs used in the 16th century to modern nails like the Russell-Taylor nail. It covers nail types, biomechanics, insertion techniques, and key design considerations like diameter, cross-section shape, curves, and locking mechanisms. The goal of intramedullary nailing is to provide stable internal splinting of long bone fractures through closed fixation techniques.
CORA (center of rotation of angulation)
This document discusses the concept of the center of rotation of angulation (CORA) in orthopedic surgery. The CORA is the point about which a deformed bone may be rotated to achieve correction of an angular deformity without introducing a translational deformity. Proper identification of the CORA allows selection of the optimal correction axis and type of osteotomy, such as opening, closing, or dome osteotomy, to realign the bone. Correction along the bisector line passing through the CORA ensures pure angular correction without residual translation. Identification of multiple CORAs indicates more complex multi-apical or translational deformities requiring different surgical techniques.

This document discusses the treatment of intertrochanteric hip fractures with different fixation devices. It notes that cephalomedullary devices are preferable to dynamic hip screws for fractures with posteromedial comminution or subtrochanteric extension due to their ability to provide controlled collapse and reduce bending forces. The document emphasizes the importance of pre-operative planning, proper reduction techniques, and achieving a tip-apex distance under 25mm for successful fixation with cephalomedullary devices.
Infection
This document discusses principles for managing acute infection after operative fracture fixation. It notes an infection rate of 1-2% for closed fractures and 6-7% for open fractures. Risk factors for surgical site infection include older age, comorbidities, drugs, prior infections, and emergency operations. Factors contributing to acute infection include contamination, a medium for bacteria to grow, mechanical instability, and dead soft tissues. Strict protocols around cleaning, masking, handwashing, and isolating MRSA patients can reduce contamination risk. Careful surgical technique, debridement, hemostasis, and temporary fixation can address other risk factors. Signs of acute infection include swelling, pain, fever and elevated inflammatory markers.

Poller or blocking screw
Poller or blocking screws are used to stabilize fractures treated with small diameter intramedullary nails. They guide the nail like "poller" traffic devices guide vehicles. Blocking screws increase stability of distal and proximal metaphyseal fractures after nailing and can help manage malunited fractures. They work by narrowing the canal to guide the nail anteriorly and prevent sagittal plane deformity. Blocking screws are typically placed medially and laterally as close to the fracture as possible for optimal stabilization. Their placement on the concave side of deformities helps improve reduction by deflecting the nail.
Prosthesis selection
The document discusses different types of knee prostheses from least to most constrained, including cruciate-retaining, posterior-stabilized, constrained non-hinged, and constrained hinged designs. It covers indications, advantages, disadvantages, and key design aspects such as femoral rollback and radiographic appearance for each type. Mobile bearing and all-polyethylene designs are also briefly discussed.

Three column fixation for complex PROXIMAL TIBIA FRACTURES
This study introduces a "three-column fixation" concept for treating complex tibial plateau fractures (Schatzker Types V and VI) based on computed tomography scans. The study evaluates clinical outcomes in 29 patients treated with this column-specific fixation technique. At 2-year follow up, patients had good functional outcomes with SF-36, HSS, and lower extremity measure scores averaging 89, 90, and 87 respectively. Radiographic measurements also showed well-maintained alignment without significant malreduction. The study concludes that three-column fixation is an effective and safe method for multiplanar complex tibial plateau fractures.
HIgh Tibial Osteotomy: when and how
1) The document discusses the planning of a high tibial osteotomy (HTO) procedure, including a brief history of osteotomies, knee axis anatomy, indications for HTO, preoperative planning considerations, and techniques for planning correction angles and wedge sizes.
2) Key factors in planning include determining the nature and location of deformity, ideal candidates for HTO vs other procedures, and calculating the needed correction angle based on methods like the Fujisawa scale.
3) Precise planning is important for procedures like open vs closed wedge osteotomy and correcting any concomitant deformities in the sagittal or transverse planes.
Bone grafting
This document discusses bone grafting and grafting techniques. It defines what a graft is, describes different types of bone grafts including autografts, allografts, and bone graft substitutes. It covers the biological process of bone graft incorporation and lists various techniques for harvesting and placing bone grafts, such as onlay grafts, dual onlay grafts, and fibula grafts. Risks, advantages, and disadvantages of different graft options are also summarized.

Ao philosophy
The document outlines the evolution of AO principles from their founding in 1958 to present day. The original principles emphasized anatomical reduction, rigid fixation, and preservation of soft tissues. However, over time the principles shifted to emphasize functional reduction, stable fixation, and preservation of blood supply as it was realized this approach better supported biological healing. The document traces this evolution from the original AO pioneers to modern techniques like minimally invasive plating that further the goal of improving patient outcomes.

Spine Disc Surgeries - Discectomy and Decompression
The document discusses various spinal decompression procedures including diskectomy, laminectomy, and foraminotomy. Diskectomy involves removing a portion of a herniated disc to relieve nerve compression. Laminectomy and laminotomy remove part of the lamina bone to widen the spinal canal to relieve pressure on nerves. Foraminotomy enlarges the openings where nerves exit the spine. These procedures provide relief from pain caused by damaged vertebrae or discs pressing on spinal nerves.
Dr. Sunil Sinsinwar MS ORTHO
The document summarizes key points from a seminar on principles and techniques of AO osteosynthesis. It discusses the history of osteosynthesis and principles put forth by AO, including anatomical reduction, stable internal fixation, preservation of blood supply, and early mobilization. Biomechanical aspects like plate types, plate functions, and principles of plate fixation are covered. Details are provided on dynamic compression plates and limited contact dynamic compression plates. Additional topics include prebending plates, number of screws used, and placement distance from fractures. Reconstruction plates are also mentioned.
Dynamic hip screw
This document discusses the dynamic hip screw (DHS), used to treat intertrochanteric hip fractures. The DHS provides controlled collapse and dynamic action to reduce complications like screw cut-out. Key steps of the procedure include closed reduction of the fracture, guide pin and plate insertion at 135 degrees, and measuring screw length. Factors like tip-apex distance and screw position are important to prevent complications. The DHS works by creating compression as the lag screw collapses into the barrel post-operatively.
