Penile fractures are the result of rupture of the tunica albuginea. They are fairly rare and can co-occur with partial or complete urethral rupture, though this is rare. Urethral damage occurs in 10–38% of cases. Fractures are treated with emergency surgery, and can be diagnosed with ultrasound, especially in pediatric cases. Penile fractures are caused by trauma to the erect penis, typically by suddenly bending it laterally during penetrative intercourse with the receptive partner on top of the penetrating partner, or during masturbation. They can be diagnosed by the "eggplant sign" and are characterized by a loud popping sound at the time of the injury, the result of the tunica albuginea rupturing. Other symptoms include severe pain, loss of erection, and swelling. Symptoms of urethral injury include hematuria, blood at the meatus, and dysuria. If left untreated, complications result in 28–53% of cases; these include permanent curvature of the penis, fistula, urethral diverticulum, priapism, and erectile dysfunction.
Degloving and avulsion injuries involve the removal of the penis skin, which is a serious medical emergency. Treatment of these injuries involves either closure of the torn skin, or a skin graft to replace the skin lost in the injury. Skin grafts are constructed to attempt to preserve erectile function and sensation.
A popping or cracking sound, significant pain, swelling, immediate loss of erection leading to flaccidity, and skin hematoma of various sizes are commonly associated with the sexual event.
Penile fracture is rupture of one or both of the "tunica albuginea", the fibrous coverings that envelop the penis's "corpora cavernosa". It is caused by rapid blunt force to an erect penis, usually during vaginal intercourse, or aggressive masturbation. It sometimes also involves partial or complete rupture of the urethra or injury to the dorsal nerves, veins and arteries.
Vulvar trauma is more common in prepubertal children due to small labial fat pads and more physical activity. Adults are more protected. Though some injuries are serious, most are accidental minor blunt traumas. The most common type of injury is a straddle injury, which can be incurred through normal activities like bicycle riding. Due to the vascularity of the vulva, it may form a large hematoma when injured. The vulva can also be injured through sexual assault. Vulvar trauma can occur concurrently with vaginal trauma, especially if a sharp object is involved.
Vaginal trauma can occur when something is inserted into the vagina, for example, a sharp object, causing penetrating trauma.
Paraphimosis is an uncommon medical condition in which the foreskin of a penis becomes trapped behind the glans penis, and cannot be "reduced" (pulled back to its normal flaccid position covering the glans). If this condition persists for several hours or there is any sign of a lack of blood flow, paraphimosis should be treated as a medical emergency, as it can result in gangrene.
Paraphimosis is usually caused by medical professionals or parents who handle the foreskin improperly: The foreskin may be retracted during penile examination, penile cleaning, urethral catheterization, or cystoscopy; if the foreskin is left retracted for a long period, some of the foreskin tissue may become edematous (swollen with fluid), which makes subsequent reduction of the foreskin difficult.
Rupture of the urethra is an uncommon result of penile injury, incorrect catheter insertion, straddle injury, or pelvic girdle fracture. The urethra, the muscular tube that allows for urination, may be damaged by trauma. When urethral rupture occurs, urine may extravasate (escape) into the surrounding tissues. The membranous urethra is most likely to be injured in pelvic fractures, allowing urine and blood to enter the deep perineal space and subperitoneal spaces via the genital hiatus. The spongy urethra is most likely to be injured with a catheter or in a straddle injury, allowing urine and blood to escape into the scrotum, the penis, and the superficial peritoneal space. Urethral rupture may be diagnosed with a cystourethrogram. Due to the tight adherence of the fascia lata, urine from a urethral rupture cannot spread into the thighs.
Individuals with Jefferson fractures usually experience pain in the upper neck but no neurological signs. The fracture may also cause damage to the arteries in the neck, resulting in lateral medullary syndrome, Horner's syndrome, ataxia, and the inability to sense pain or temperature.
In rare cases, congenital abnormality may cause the same symptoms as a Jefferson fracture.
The Maisonneuve fracture is a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament. This type of injury can be difficult to detect.
The Maisonneuve fracture is similar to the Galeazzi fracture in the sense that there is an important ligamentous disruption in association with the fracture. The fracture is named after the surgeon Jules Germain François Maisonneuve.
Webbed penis, also called penis palmatus or penoscrotal fusion, is an acquired or congenital condition in which the scrotal skin extends onto the ventral penile shaft. The penile shaft is buried in scrotum or tethered to the scrotal midline by a fold or web of skin. The urethra and erectile bodies are usually normal. Webbed penis is usually asymptomatic, but the cosmetic appearance is often unacceptable. This condition may be corrected by surgical techniques.
In the congenital form, the deformity represents an abnormality of the attachment between the penis and the scrotum; the penis, the urethra, and the remainder of the scrotum typically are normal.
Webbed penis may also be acquired (iatrogenic) after circumcision or other penile surgery, resulting from excessive removal of ventral penile skin; the penis can retract into the scrotum, resulting in secondary phimosis (trapped penis).
One procedure for webbed penis is the insertion of a subcutaneous soft silicone implant under the penile skin. The procedure was developed by urologist James J. Elist.
A Jefferson fracture is a bone fracture of the anterior and posterior arches of the C1 vertebra, though it may also appear as a three- or two-part fracture. The fracture may result from an axial load on the back of the head or hyperextension of the neck (e.g. caused by diving), causing a posterior break, and may be accompanied by a break in other parts of the cervical spine.
It is named after the British neurologist and neurosurgeon Sir Geoffrey Jefferson, who reported four cases of the fracture in 1920 in addition to reviewing cases that had been reported previously.
Signs and symptoms include crepitus (a crunching sound made when broken bone ends rub together), pain, tenderness, bruising, and swelling over the fracture site. The fracture may visibly move when the person breathes, and it may be bent or deformed, potentially forming a "step" at the junction of the broken bone ends that is detectable by palpation. Associated injuries such as those to the heart may cause symptoms such as abnormalities seen on electrocardiograms.
The upper and middle parts of the sternum are those most likely to fracture, but most sternal fractures occur below the sternal angle.
As with other types of fractures, scapular fracture may be associated with pain localized to the area of the fracture, tenderness, swelling, and crepitus (the crunching sound of bone ends grinding together). Since scapular fractures impair the motion of the shoulder, a person with a scapular fracture has a reduced ability to move the shoulder joint. Signs and symptoms may be masked by other injuries that accompany the scapular fracture.
Bulbar urethral necrosis is a problem that can occur after a pelvic fracture associated urethral distraction defect (PFUDD).
The term "Colles fracture" is classically used to describe a fracture at the distal end of the radius, at its cortico-cancellous junction. However, now the term tends to be used loosely to describe any fracture of the distal radius, with or without involvement of the ulna, that has dorsal displacement of the fracture fragments. Colles himself described it as a fracture that “takes place at about an inch and a half (38mm) above the carpal extremity of the radius” and “the carpus and the base of metacarpus appears to be thrown backward”. The fracture is sometimes referred to as a "dinner fork" or "bayonet" deformity due to the shape of the resultant forearm.
Colles' fractures can be categorized according to several systems including Frykman, Gartland & Werley, Lidström, Nissen-Lie and the Older's classifications.
People usually present with a history of an injury and localized pain. There is often a deformity in the wrist with associated swelling. Numbness of the hand can occur because of compression on the median nerve across the wrist (carpal tunnel syndrome). The wrist deformity often limits motion of the fingers.
A pelvic fracture can cause the urethra to separate, leading to a variable length of scar that can severely hamper the ability to urinate normally. The urethra is a tubular conduit that transports urine out of the bladder. The bulbar urethra is a segment of the male urethra that is in between the penile urethra and the membrano-prostatic urethra that typically has a robust blood supply. This blood supply includes antegrade flow from the paired bulbar arteries and circumflex arteries, and retrograde flow from the paired dorsal arteries of the penis.
Sclerosing lymphangitis is a skin condition characterized by a cordlike structure encircling the coronal sulcus of the penis, or running the length of the shaft, that has been attributed to trauma during vigorous sexual play.
Nonvenereal sclerosing lymphangitis is a rare penile lesion consisting of a minimally tender, indurated cord involving the coronal sulcus and occasionally adjacent distal penile skin. This disorder most often occurs after vigorous sexual activity and resolves spontaneously.
Etiology of Sclerosing lymphangitis is unknown but has been postulated to be secondary to thrombosis of lymphatic vessels. Spontaneous recovery can occur anywhere within a couple weeks to several months.
Although it is commonly recommended the patient abstain from any sexual activitiy during the recovery, there is no evidence that this expedites recovery nor that not abstaining worsens the condition.
Swelling, deformity, tenderness and loss of wrist motion are normal features on examination of a person with a distal radius fracture. Examination should rule out a skin wound which might suggest an open fracture. It is imperative to check for loss of sensation, loss of circulation to the hand, and more proximal injuries to the forearm, elbow and shoulder. The most common associated neurological finding is decreased sensation over the thenar eminence due to associated median nerve injury.
A classic "dinner fork" deformity may be seen in dorsally angulated fractures due to dorsal displacement of the carpus. The reverse deformity may be seen in volarly angulated fractures.
The fracture is most commonly caused by people falling onto a hard surface and breaking their fall with outstretched hand (FOOSH)–falling with wrists flexed would lead to a Smith's fracture. Originally it was described in elderly and/or post-menopausal women. It usually occurs about three to five centimetres proximal to the radio-carpal joint with posterior and lateral displacement of the distal fragment resulting in the characteristic "dinner fork" or "bayonet" like deformity. Colles fracture is a common fracture in people with osteoporosis, second only to vertebral fractures.
Despite the similarity of name, an epispadias is not a type of hypospadias, and involves a problem with a different set of embryologic processes.
Women can also have this type of congenital malformation. Epispadias of the female may occur when the urethra develops too far anteriorly, exiting in the clitoris or even more forward. For females, this may not cause difficulty in urination but may cause problems with sexual satisfaction. Frequently, the clitoris is bifurcated at the site of urethral exit, and therefore clitoral sensation is less intense during sexual intercourse due to frequent stimulation during urination. However, with proper stimulation, using either manual or positional techniques, clitoral orgasm is definitely possible.
Tibial plateau fractures typically presents with knee effusion, swelling of the knee soft tissues and inability to bear weight. The knee may be deformed due to displacement and/or fragmentation of the tibia which leads to loss of its normal structural appearance. Blood in the soft tissues and knee joint (hemarthrosis) may lead to bruising and a doughy feel of the knee joint. Due to the tibial plateau's proximity to important vascular (i.e. arteries, veins) and neurological (i.e. nerves such as peroneal and tibial) structures, injuries to these may occur upon fracture. A careful examination of the neurovascular systems is imperative. A serious complication of tibial plateau fractures is compartment syndrome in which swelling causes compression of the nerves and blood vessels inside the leg and may ultimately lead to necrosis or cell death of the leg tissues.
This fracture pattern is named after Paul Jules Tillaux, a French Anatomist and Surgeon (1834-1904).
