An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body.
Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
Intramedullary is a medical term meaning the inside of a bone. Examples include intramedullary rods used to treat bone fractures in orthopedic surgery and intramedullary tumors occurring in some forms of cancer or benign tumors such as an enchondroma .
Recovery following spinal fusion is extremely variable, depending on individual surgeon's preference and the type of procedure performed. [20] The average length of hospital stay for spinal fusions is 3.7 days. [6] Some patients can go home the same day if they undergo a simple cervical spinal fusion at an outpatient surgery center.

Tommy John, for whom the surgery is named, in 2008. At the time of John's operation, Jobe estimated the chance for success of the operation at one in 100. [18] By 2009, the odds of complete recovery had risen to 85–92%. [19] Following his 1974 surgery, John missed the entire 1975 season rehabilitating his arm before returning for the 1976 season.
The surgery is quick (typically lasting between 30 and 90 minutes), minimally invasive, and can have a significantly shorter recovery time than an arthroplasty (knee replacement). Chronic articular cartilage defects do not heal spontaneously. [1]
Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. [1] [2] [3] It was originally used to treat problems like unequal leg length, but since the 1980s is most commonly used to treat issues like hemifacial microsomia, micrognathism (chin so small it causes health problems), craniofrontonasal ...
[2] [1] Options for surgery may include a total hip replacement or stabilizing the fracture with screws. [2] Treatment to prevent blood clots following surgery is recommended. [1] About 15% of women break their hip at some point in life; [1] women are more often affected than men. [1] Hip fractures become more common with age. [1]
