Without proper treatment, permanent deformity can be the result If left untreated a swan neck deformity will likely develop. Boxer's Fracture. Mechanism: Fracture of the head of the 5th metacarpal caused by an axial load most often due to punching a person or object, hence the name Avascular necrosis of the femoral head is a type of osteonecrosis due to disruption of blood supply to the proximal femur. There are approximately 10000 to 20000 new cases reported each year in the United States alone. It can occur due to a variety of causes, either traumatic or atraumatic in origin. These causes include fractures, dislocations, chronic steroid use, chronic alcohol use. Boutonniere deformity describes a medical condition in which the finger is flexed at the proximal interphalangeal joint (PIP) and hyperextended at the distal interphalangeal joint (DIP). This is usually a result of trauma in the acute setting and is caused by a rupture of the PIP central slip. This results in damage to the extensor function of the affected digit
A mallet finger is a deformity of the finger. It occurs when the tendon that straightens the finger (the extensor tendon) is damaged at the fingertip. This can commonly happen when an object (like a ball) strikes the tip of the finger or thumb. It can also happen when forceful bending of the fingertip occurs. This force tears the tendon at the.

The most common cause of swan neck deformities is Rheumatoid arthritis. In this condition, the volar plate (palmar ligament of the PIP joint) is loosened. This create an imbalance in between extensor and flexor tendons, resulting in a PIP joint hyperextension leading to a DIP joint hyperflexion. Swan neck deformity may also appear as a result. The trunion is the junction of the femoral head and the femoral stem in a hip replacement. Trunionosis is a type of implant wearing out at this junction. It occurs where the femoral stem component attaches to the femoral head component. Even though these two parts fix together very tightly, there is always some minor micro-motion, which adds up. The hand (wrist and fingers) is one of the regions most frequently affected by rheumatic arthritis (RA). The nature of the alterations involved means it is possible to interpret the clinical picture as RA even from the external appearance. Obviously the functional handicap affects activities of daily living, and the insult to the patient's aesthetic sensibilities imposes an additional.
Boutonniere deformity is a deformed position of the fingers or toes, in which the joint nearest the knuckle (the proximal interphalangeal joint, or PIP) is permanently bent toward the palm while the farthest joint (the distal interphalangeal joint, or DIP) is bent back away (PIP flexion with DIP hyperextension).Causes include injury, inflammatory conditions like rheumatoid arthritis, and.

Inadequately healed or untreated volar plate injuries can lead to chronic swelling, stiffness, pain, flexion contracture, swan-neck deformity, and posttraumatic arthritis (58,60,61). Scar tissue forms at the volar plate attachment, which impairs flexion of the PIP joint Swan Neck Deformity • Finger with a hyper-extended PIP joint and a flexed DIP joint. • The extensor tendon gets out of balance, which allows the DIP joint to get pulled downward into flexion. 40 A schwannoma is a type of nerve tumor of the nerve sheath. It's the most common type of benign peripheral nerve tumor in adults. It can occur anywhere in your body, at any age. A schwannoma typically comes from a single bundle (fascicle) within the main nerve and displaces the rest of the nerve. When a schwannoma grows larger, more fascicles.
Ligament Injury and Dislocation of the Hand: History and Exam, Nonoperative/Surgical Indications, Contraindication to Reconstruction, Surgical Technique, Complications and Postoperative Protocol. FEATURING Chia Wu. 36 views The volar plate keeps the finger from bending backwards at the PIP joint, and, together with the collateral ligaments, stabilizes the PIP joint from displacement. Volar plate injuries can be caused by disease or trauma. Diseases such as rheumatoid arthritis can weaken and loosen the volar plate, leaving it susceptible to injury
Retinacular Cysts. Tender masses that appear in the palm by the base of a finger are usually retinacular cysts. Retinacular cysts are simply ganglion cysts that come from the flexor tendon sheath of the finger. Retinacular cysts often lead to pain when gripping objects. Fortunately, they are benign and easily treated Swan-neck deformity, the most well known complication of untreated mallet finger, is caused when the lateral bands displace laterally, causing increased extension forces on the PIP joint. Key Points. Most mallet finger injuries can be treated conservatively with the DIP joint splinted in extension. The DIP joint must be held in extension. Hand fractures account for about 1.5% of all emergency room visits and 40% of upper extremity fractures. Unfortunately, complications occur following these injuries. When the underlying osseous structure is affected with nonunion or malunion, it can further compromise hand function, therefore diagnosis and treatment of these complications is an important part of caring for patient If swan-neck deformity develops, splint PIP at 30-45 flexion via dorsal block splint. Casting is an option, and may have better outcomes via constant circumferential positioning. 6-8 weeks Remove splint for exercise, otherwise splint is worn continuously. AROM of DIP flex/ext, 10 reps hourly. Start at 10 degrees flexion, progress in 10-2 The tibial spine is most often fractured from severe injury or trauma to the knee that places severe stress on the ACL. This ligament stress can pull tiny fragments of the bone away from the tibia. Symptoms. The most common symptom of a tibial spine fracture is acute pain in the front or center of the knee. Patients may also notice swelling.
b) Swan-neck deformity c) Fixed flexion deformity d) Boutonnière deformity. Answer: d) Boutonnière deformity. What is a Boutonniere deformity? A Boutonniere deformity results from a Zone III extensor tendon (central slip) injury, and presents as PIP flexion and DIP hyper-extension If possible, an alternate, uninfected site should be used. However, acutely inflamed joints may be generally warm, tender, and red, thus mimicking extra-articular infection and making it hard to find an uninvolved insertion site Animal bites can result in skin lacerations, puncture wounds, crushed bones, torn ligaments, tendons, and muscles. They can injure or damage blood vessels and nerves. Compounding the physical injuries, several types of infections, including rabies, are transmittable from the animal's mouth into the hand Mallet finger refers to injuries of the extensor mechanism of the finger at the level of the distal interphalangeal joint (DIP).They are the most prevalent finger tendon injury in sport. They may represent an isolated tendinous injury or occur in combination with an avulsion fracture of the dorsal base of the distal phalanx
Cervical myelopathy is a form of myelopathy that involves compression of the spinal cord in the cervical spine (neck).

Often with concomitant neurovascular damage Kienbock's disease causes one of the bones in the wrist (lunate bone) to slowly break down due to low blood supply.This process is called osteonecrosis.Symptoms include pain, swelling, limited movement, and decreased grip strength. The symptoms usually start in adulthood, but can occur at any age Description. Tuft's finger fracture (break) of the tuft, is the distal tip of the last bone in the finger. It is also known as distal phalanx fracture or P3 fracture and is the most common fracture of the hand. The middle finger is most vulnerable to fracture simply because of its length compared with adjacent fingers
Mallet Finger Symptoms. People with mallet finger may delay seeking medical attention -- even though they may be in a great deal of pain -- simply because they can still use their hand. Symptoms. Dupuytren's contracture. Dupuytren's contracture is a painless deformity of the hand in which one or more fingers (in this case, the two fingers farthest from the thumb) are bent toward the palm and can't be fully straightened. It results from a thickening and scarring of connective tissue under the skin in the palm of the hand and in the fingers rate physical examination of a child with a foot injury and the complexities of radiographic evaluation of the immature foot, a high index of suspicion for the presence of a fracture facilitates early and accurate diagnosis.
