A distal radius fracture, often referred to as a wrist fracture, occurs near the end of the radius bone, close to the wrist. This type of fracture is common, especially among older adults and those who engage in high-impact activities. When the fracture is severe or displaced, surgical intervention may be required. What is Distal Radius Fracture Fixation? Surgical fixation of a distal radius fracture involves realigning the broken bone and securing it with hardware to ensure proper healing. There are several methods: Open Reduction and Internal Fixation (ORIF) : This involves making an incision to directly access the fracture site. The bones are then realigned and held together with plates and screws. External Fixation : In cases where ORIF is not suitable, external fixation can be used. Pins are inserted into the bone above and below the fracture, and these are connected to an external frame that holds the bone in place. Important Anatomic Structures Radius : One of the two bones in t...

Endoscopic Carpal Tunnel Release : This minimally invasive technique involves one or two small incisions. A camera and special instruments are used to cut the ligament. Important Anatomic Structures Median Nerve : A crucial nerve running down the arm into the hand, controlling sensations to the palm side of the thumb and fingers, and motor funct...

Cubital tunnel syndrome, also known as ulnar nerve entrapment, is a condition where the ulnar nerve becomes compressed or irritated as it passes through the cubital tunnel at the elbow. This can cause numbness, tingling, and pain in the forearm and hand, often affecting the ring and little fingers. When conservative treatments fail to alleviate symptoms, cubital tunnel release surgery may be recommended. What is Cubital Tunnel Release Surgery? Cubital tunnel release surgery aims to relieve pressure on the ulnar nerve by enlarging the cubital tunnel or repositioning the nerve. There are two primary techniques for this surgery: In-Situ Decompression : This involves making an incision along the inner elbow to access the cubital tunnel. The surgeon then cuts the ligament that forms the roof of the tunnel, increasing the space for the ulnar nerve. Ulnar Nerve Transposition : In this technique, the ulnar nerve is moved from its original position to a new location, either under the skin, musc...

Orthopedic conditions often present a complex landscape of anatomical nuances, diverse treatment modalities, and a variety of surgical interventions. Among these, issues related to the shoulder, particularly acromions and adhesive capsulitis (frozen shoulder), are significant due to their impact on mobility and quality of life. This blog will delve into the different types of acromions, the nature of adhesive capsulitis, the drugs used in its treatment, and some common surgical procedures in orthopedics. Types of Acromions The acromion is a bony process on the scapula (shoulder blade) that extends over the shoulder joint. It's crucial in the overall mechanics of the shoulder and can be categorized into three main types based on its shape: Type I (Flat Acromion) : This is the most benign shape, with a flat under-surface that poses the least risk for impingement of the rotator cuff tendons. Type II (Curved Acromion) : This type features a curved shape, which can increase the likeliho...

Function: The Pentose Phosphate Pathway (PPP) is vital for producing NADPH and ribose-5-phosphate, essential for fatty acid synthesis, nucleotide synthesis, and maintaining redox balance. Location: This pathway occurs in the cytoplasm of cells. Steps and Enzymes Involved: Oxidative Phase: Step 1: Glucose-6-phosphate is oxidized by glucose-6-phosphate dehydrogenase (G6PD), producing 6-phosphoglucono-δ-lactone and NADPH. Reaction: Glucose-6-phosphate + NADP⁺ → 6-phosphoglucono-δ-lactone + NADPH + H⁺ Step 2: 6-Phosphoglucono-δ-lactone is hydrolyzed by lactonase to form 6-phosphogluconate. Reaction: 6-phosphoglucono-δ-lactone + H₂O → 6-phosphogluconate Step 3: 6-Phosphogluconate undergoes oxidative decarboxylation by 6-phosphogluconate dehydrogenase to produce ribulose-5-phosphate, CO₂, and NADPH. Reaction: 6-phosphogluconate + NADP⁺ → ribulose-5-phosphate + CO₂ + NADPH Non-Oxidative Phase: Step 4: Ribulose-5-phosphate is isomerized to ribose-5-phosphate by phosphopentose isomerase. Reacti...
