Massive bone defects (>8 cm) will not unite without an additional intervention. They require a predictable, durable, and efficient method to regrow bone. The Ilizarov method of tension stress, or distraction osteogenesis, first involves a low-energy osteotomy1 - 5. The bone segments are then pulled apart, most often using an external device at a specific rate and rhythm (distraction phase), after which the newly formed bone (the regenerate) requires time for consolidation. The consolidation phase is variable and usually requires a substantially greater amount of time before the external device can be removed. Our technique of tibial bone transport over an intramedullary nail using cable and pulleys combines internal and external fixation, allowing the external fixator to be removed at the end of the distraction phase. This increases the efficiency of limb reconstruction and decreases the external-fixator-associated complications.
What is an ingrown hair cyst? An ingrown hair cyst refers to an ingrown hair that turns into a cyst — a large bump that extends between the skin’s surface and deep underneath it. The appearance is a cross between a regular ingrown hair and an acne cyst, though this is a different condition. These types of cysts are common among people who shave, wax, or use other methods to remove their hair. Although you may be eager to get rid of these cysts simply because of their appearance, it’s also important to watch for signs of an infection. Keep reading to learn what causes these cysts to form, plus how to treat them and prevent them from returning.
Three to five years after gastric bypass surgery, some patients start to regain weight because the size of their stoma (the opening at the bottom of the stomach pouch) or their stomach pouch itself has increased. This can keep you from feeling full after small meals.
To resolve this problem, our surgeons use new surgical tools to create and suture folds into the pouch, reducing its volume and at the stoma to decrease its diameter. The surgeon performs the procedure entirely through the mouth -- inserting an endoscope under heavy sedation -- so there are no external incisions into the body.
Thousands of Canadians undergo surgery every year, so how can you best prepare? The first step is having a dialogue, says Sunnybrook anesthesiologist Dr. Colin McCartney. Read the blog for more: http://sunnyview.sunnybrook.ca
Nose cautery can help prevent nosebleeds. The doctor uses a chemical swab or an electric current to cauterize the inside of the nose. This seals the blood vessels and builds scar tissue to help prevent more bleeding. For this procedure, your doctor made the inside of your nose numb.
Detailed examination of the joints is usually not included in the routine medical examination. However, joint related complaints are rather common, and understanding anatomy and physiology of both normal function and pathologic conditions is critically important when evaluating the symptomatic patient. By gaining an appreciation for the basic structures and functioning of the joint, you'll be able to "logic" your way thru the exam, even if you can't remember the eponym attached to each specific test!

What is Laparoscopic Surgery:
Laparoscopic surgery describes procedures performed using one or multiple small incisions in the abdominal wall in contrast to the larger, normally singular incision of laparotomy. The technique is based around principles of minimally invasive surgery (or minimal access surgery): a large group of modern surgical procedures carried out by entering the body with the smallest possible damage to tissues. In abdominopelvic surgery, minimally invasive surgery is generally treated as synonymous with laparoscopic surgery as are procedures not technically within the peritoneal cavity, such as totally extraperitoneal hernia repair, or extending beyond the abdomen, such as thoraco-laparoscopic esophagectomy. The term laparoscopy is sometimes used interchangeably, although this is often reserved to describe a visual examination of the peritoneal cavity or the purely scopic component of a laparoscopic procedure. The colloquial keyhole surgery is common in non-medical usage.
Surgical Objective of Laparoscopic Surgery:
The objective of a laparoscopic approach is to minimize surgical trauma when operating on abdominal or pelvic structures. When correctly indicated and performed, this can result in smaller scars, reduced postoperative morbidity, shorter inpatient durations, and a faster return to normal activity. For a number of abdominopelvic procedures, a laparoscopic approach is now generally considered to be the gold-standard treatment option.

Developments of Laparoscopic Surgery:
Following a number of smaller-scale applications of minimally invasive techniques to abdominopelvic surgery, laparoscopic surgery became a major part of general surgical practice with the introduction of laparoscopic cholecystectomy in the 1980s and the subsequent pioneering of endoscopic camera technology. This led to the widespread adoption of the technique by the early- to mid-1990s. The portfolio of procedures that can be performed laparoscopically has rapidly expanded with improvements in instruments, imaging, techniques and training — forming a central component of modern surgical practice and cross-specialty curricula [2]. Techniques such as laparoscopically assisted surgery and hand-assisted laparoscopic surgery have allowed the application of laparoscopic techniques to a greater variety of pathology. Single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and minilaparoscopy-assisted natural orifice surgery continue to push forward the applications of minimally invasive abdominopelvic techniques; however, the widespread practice and specific indications for these remain to be fully established. More recently, robotic surgery has been able to build on laparoscopic principles through developments in visualization, ergonomics, and instrumentation.

Urological surgeons have become proficient at performing complex pelvic urological procedures, such as radical prostatectomy, using the laparoscopic approach. Declan Murphy and Daniel Moon share their experience of four less common procedures they have performed recently using laparoscopic techniques. These include: excision of a urachal cyst; partial cystectomy for endometriosis (combined endoscopic-laparoscopic approach); repair of an intra-peritoneal bladder rupture; and repair of a ureteric injury (combined endoscopic-laparoscopic approach).
