Synonyms and Keywords: Pilon fracture, Plafond fracture

Overview

Pilon fracture is a fracture of the distal part of the tibia bone (also called the shinbone). Meanwhile, the injured tibia may break into one or multiple pieces.

Historical Perspective

There are no reliable information regarding the historical perspective of the Pilon fracture

Causes

The Pilon fractures most often result from high-energy trauma like: a car or motorcycle accident, fall from height, or skiing accident due to the rotational or axial-loading forces to the tibia bone. Meanwhile, there are other causes responsible for this type of fracture such as:

  • Pressure during car accidents
  • Twisted ankle side to side
  • Rotated ankle side to side
  • Rolling ankle in or out
  • Hyper-flextion
  • Hyper-Extention
  • Tripping
  • Falling from a height
  • Jumping from a height

As a person age, two factors cause higher risk of fractures:

  • Weaker bones
  • Greater risk of falling

Stress fractures as a common causes of fractures can be found due to the repeated stresses and strains. Importantly children having more physically active lifestyles than adults, are also prone to fractures. People with any underlying diseases such as osteoporosis, infection, or a tumor affecting their bones having a higher risk of fractures. As mentioned in previous chapters, this type of fracture is known as a pathological fracture. Stress fractures, which result from repeated stresses and strains, commonly found among professional sports people, are also common causes of fractures.

Causes in Alphabetical Order

List the causes of the disease in alphabetical order:

Pathophysiology

The main etiology of the Pilon fracture is thought to excessive inversion stress to the ankle joint.

Mechanism

Pathophysiology

Its known that the Pilon fracture in normal healthy adults can be caused due to the high-energy trauma (e.g., motor vehicle accidents), sport related injuries, falling from height. But it should be noted that the most important Risk factors for insufficiency fractures is chronic metabolic disease such as steoporosis, osteopenia, eating-disordered behavior, higher age, prolonged corticosteroid usage, female gender, lower BMI, history of a recent falling, and prior fracture.

  • The pattern of bone fracture and severity of injury depends on variety of factors such as:
    • Patients age
    • Patients Weight
    • Patients past medical history specifically any bone diseases affecting the quality of bone (such as osteoporosis, malignancies)
    • Energy of trauma
    • Bone quality
    • Position of the specific organ during the trauma
  • The below-mentioned processes cause decreased bone mass density:

Differentiating Pilon fracture from other Diseases

In the orthopedic medicine its important to know that the Pilon fracture should be evaluated using radiography for both confirming diagnosis and also for evaluating the surrounding tissues.

  • Acute compartment syndrome of ankle joint
  • Ankle Dislocation
  • Soft tissue Injury around the ankle ,
  • Deep Venous thrombosis
  • Thrombophlebitis
  • Foot Fracture
  • Gout
  • Pseudogout
  • Rheumatoid Arthritis
  • Tibia Fracture
  • Fibula Fracture
  • bimalleolar fracture
  • trimalleolar fracture
  • triplane fracture
  • Tillaux fracture
  • Bosworth fracture
  • pilon fracture
  • Wagstaffe-Le Forte fracture
  • Charcot-Marie-Tooth disease: in cases with repeated Pilon fractures

Epidemiology and Demographics

Of all cases with the Pilon fracture only 15% of cases are true Pilon fractures. The male-to-female ratio for Pilon fracture is 2:1. The frequency of Pilon fractures in adults and children is around 100 cases in 100,000 per year and 190 cases in 100,000 per year, respectively.

Risk Factors

There are different risk factors that presidpose patient for the Pilon fracture that include:

  • High-risk contact sports
  • Higher age (elderly adults are higher prone to such fractures)
  • Reduced bone density (osteoporosis)
  • Direct blow
  • Road / traffic accidents
  • Falling
  • Direct trauma to the arm/forearm
  • Taking part in any rough or high-impact sport
  • Street fights, gunshot wounds, and domestic violence, may also cause the Pilon fracture
  • Road traffic accidents.

Classification

The Pilon fracture may be classified based on the exact location of fracture:

Screening

Osteoporosis is an important risk factor for human affecting human bone especially in men with the age of older than 50 years old and postmenopausal and women.

Based on the US Preventive Services Task Force (USPSTF) there are three groups of patients need to be screened for the osteoporosis:

  • ·       Men with no history of osteoporosis
  • ·       Women with the age of 65≤ year old, with no previous history of pathological fracture due to the osteoporosis
  • ·       Women with the age of <65 years, with 10-year fracture risk of not less than a 65-year-old white woman (who has not any other risk factor)

Accordingly women older than age of 50 are the main target for the osteoporosis screening. There is no specific recommendation to screen men for the osteoporosis.[1]

The USPSTF recommendations from 2002 included:

Meanwhile, there are two major modalities for the osteoporosis screening:

  1. ·       Dual energy x-ray absorptiometry (DXA) of the hip and lumbar spine bones
  2. ·       Quantitative ultrasonography of the calcaneus

*It should be noted of the two above mentioned modalities for screening the ultrasonograhy is preferred to the DXA due to its lower cost, lower ionizing radiation, more availability.

After the primary evaluation of the osteoporosis, the further evaluation are required in some cases such as:

·       Women with normal bone density or mild osteopenia: T-score of greater than −1.50 – should have screening for 15 years.

·       Women with moderate osteopenia: T-score of −1.50 to −1.99 – should have screening for 5 years.

·       Women with advanced osteopenia: T-score of −2.00 to −2.49 - should have screening for 1 year.

Natural History, Complications and Prognosis

Natural History

In cases with untreated Pilon fracture the malunion and deformity of arm can be occurred.

Complications

The overall complication rate in the treatment of Pilon fracture were found in around 40% of cases:

  1. Neurovascular compromise: such as Ulna nerve damage
  2. Compartment syndrome
  3. Chronic disability of the DRUJ
  4. Physeal Injury
  5. Malunion of the radius
  6. Nonunion

Prognosis

Successful treatment of Pilon fracture depends on the on-time interventions such as: accurate diagnosis and appropriate treatment and referral. Complex open fractures with soft-tissue injuries have a worse prognosis than isolated closed Pilon fractures.

Diagnosis

The diagnosis of a Pilon fracture should be confirmed using a radiographic examination.

History and Symptoms

The related signs and symptoms include:

  • Deformity
  • Skin lacerations
  • Open fractures
  • Erythema
  • Edema
  • Stiffness
  • Decreased range of motion
  • Tenderness
  • Loss of function of the forearm
  • Difficulties in detection of pulses
  • Nerve damage

In the physical exam the orthopedic surgeon should check the vascular status and amount of swelling in the forearm. In MULTI-trauma patients or in comatose or obtunded patients a tense compartment with neurological signs or stretch pain should be considered as the compartment syndrome, and the compartment pressures should be measured and monitored. Normally the pain and soft-tissue swelling are found at the injury site. This injury should be confirmed using a radiographic evaluations.

Physical Examination

The related signs and symptoms include:

  • Edema of the ankle
    • Most of the time the edema will be a non-pitting edema
    • Depends on the edema extent, it may even lead to compartment syndrome in the anterior and internal compartment of the ankle
  • Bruising
    • As a manifestation of internal injury to the local vessels by trauma or fractures bone
  • Decrease in range of motion of the ankle
    • Movement of the ankle will be painful if possible at all
  • Tenderness
  • Deformity
    • Fractured bone deformity may be touchable in the internal side of the ankle if the fracture is displaced

In the physical exam the orthopedic surgeon should check the vascular status and amount of swelling in the forearm. In polytrauma patients or in comatose or obtunded patients a tense compartment with neurological signs or stretch pain should be considered as the compartment syndrome, and the compartment pressures should be measured and monitored.

Physical examination of patients with Pilon fracture is usually remarkable for swelling, tenderness, bruises, ecchymosis, deformity and restricted range of motion of the ankle.

Appearance of the Patient

  • Patients with Pilon fracture usually appears normal unless the patients had a high energy trauma causing the open wound fracture.

Vital Signs

Skin

HEENT

Neck

Lungs

Heart

  • Cardiovascular examination of patients with Pilon fracture usually normal

Abdomen

Back

Genitourinary

  • Genitourinary examination of patients with Pilon fracture usually normal

Neuromuscular

  • Neuromuscular examination of patients with Pilon fracture is usually normal
  • However, some patients may develop neuropraxia of the branch of the Ulnar nerve resulting in decreased sensation of thumb, index and middle finger.

Laboratory Findings

There is a limited laboratory tests useful in the diagnosis of bone fractures such as the Pilon fracture. Meanwhile, aged men and women may have some abnormalities in their laboratory findings suggestive of osteoporosis.

Laboratory tests for the diagnosis of osteoporosis are:

  • Complete blood count (CBC)
  • Serum total calcium level
  • Serum Ionized calcium level
  • Serum phosphate level
  • Serum alkaline phosphatase level
  • Serum 25-(OH)-vitamin D level

X Ray

The orthopedic surgeon should consider to have at least two radiographic projections (ie, anteroposterior [AP] and lateral) of the forearm. These show the fracture, the extent of displacement, and the extent of comminution. The orthopedic surgeon should pay serious attention toward finding any foreign bodies in open fractures and gunshot injuries. Also imperative is to include the elbow and wrist joint in the radiographs of Ankle fracture to ensure that the distal radioulnar joint injuries are not missed.

CT

  • CT-scan in the case of the Pilon fractureis the best modality if you can not have an exclusive diagnosis by X-ray itself can not be made.

MRI

  • Magnetic resonance imaging (MRI) is an expensive technique that should not be used routinely.
  • MRI is a powerful diagnostic tool to assess the abnormalities of the bone, ligaments and soft tissues associated with the Pilon fracture, but it is known as a limited utility in radioulnar injuries and is not indicated in uncomplicated forearm fractures.
  • Meanwhile, the MRI can be useful in in following mentioned evaluations:
  • Evaluation of occult fractures
  • Evaluation of the post-traumatic or avascular necrosis of carpal bones
  • Evaluation of tendons
  • Evaluation of nerve
  • Evaluation of carpal tunnel syndrome

Other Imaging Findings

There are no other imaging findings associated with Pilon fracture

Other Diagnostic Studies

There are no other Diagnostic studies associated with Pilon fracture

Treatment

Immediate stabilization of patients is the first step. Then the radial fracture and the DRUJ stabilization is recommended in these cases. Open forearm fractures considered as a surgical emergency. Pilon fracture occurs in younger patients who are skeletally immature; the normally they treated using a closed reduction and casting. Since closed reduction and cast application have led to unsatisfactory results. Then, Almost always the open reduction are necessary for the Pilon fracture. There are controversies regarding the indications for intramedullary nailing of forearm fractures.

Non-Operative Treatment

  • The first step in managing a patient with a fracture is to stabilize the patient if he/she is unstable due to blood loss, etc by giving them intravenous fluids and giving them some painkillers if the pain is severe.
  • In children, the usual plan is to attempt closed reduction followed by cast immobilization. In adults, treatment with immobilization in a molded long arm cast can be used in those rare occasions of a non-displaced fracture of the ankle joint. If the fracture shifts in position, it may require surgery to put the bones back together.
  • Rigid immobilization is suggested in preference to removable splints in nonoperative treatment for the management of the Pilon fracture
  • For all patients with Pilon fracture, a post-reduction true lateral radiograph is suggested.
  • Operative fixation is suggested in preference to cast fixation for fractures with post-reduction radial shortening greater than 3 mm, dorsal tilt greater than 10º, or intra-articular displacement or step-off greater than 2 mm.
  • Patients probably do not need to begin early wrist motion routinely after stable fracture fixation.
  • Adjuvant treatment of Pilon fracture with vitamin C is suggested for the prevention of disproportionate pain
  • Lateral epicondylar fractures should be immobilized for 7 days with patients elbow flexed at 90º, with the supinated forearm , and the extended wrist for relaxing the extensor muscles.

Complications of Non-surgical therapy

Failure of non-surgical therapy is common:

  • Re-displacement to its original position even in a cast
  • Stiffness
  • Post traumatic osteoarthritis leading to wrist pain and loss of function
  • Other risks specific to cast treatment include:

Surgery

Returning to the normal physical activity after Pilon fracturecan take weeks to months of therapy under supervision an orthopedist. Meanwhile, a physiotherapy can be helpful for patient to achieve the normal wrist and elbow function caused by the immobilization. All adult Pilon fracture should be considered to be treated with open reduction and internal fixation (ORIF).

External fixation: For severe open fractures Open reduction and internal fixation: For distal Pilon fracture which depending on each patients condition the following may be needed:

Nerve placement Bone grafting Osteotomy Arthrodesis


Operation

  • There are a variety of methods and implants useful to stabilize the Pilon fracturee, ranging from closed reduction and percutaneous pin fixation to the use of intra-medullary devices.
  • However, the most common fixation methods to treat complex Pilon fracture include external fixation, and open reduction and internal fixation.

External Fixation With or Without Percutaneous Pin Fixation

  • Ankle spanning external fixation employs ligamentotaxis to restore and maintain length, alignment, and rotation of bone.
  • Reduction is typically obtained through closed or minimally open methods and preserves the fracture biology.
  • The addition of percutaneous pins enhances the ability to reduce and stabilize fracture fragments.

Complications of External Fixation

Open reduction and internal fixation with plates and screws

  • This is the most common type of surgical repair for Pilon fracture
  • During this type of procedure, the bone fragments are first repositioned (reduced) into their normal alignment.
  • The bones held together with special screws and metal plates attached to the outer surface of the bone.

Complications of open reduction and internal fixation with plates and screws =

  • Infection
  • Damage to nerves and blood vessels
  • Synostosis
  • Nonunion

Pain Management

Pain after an injury or surgery is a natural part of the healing process.

Medications are often prescribed for short-term pain relief after surgery or an injury such as:

  • opioids
  • non-steroidal anti-inflammatory drugs (NSAIDs)
  • local anesthetics

Be aware that although opioids help relieve pain after surgery or an injury, they are a narcotic and can be addictive.  It is important to use opioids only as directed by doctor.

Interventions

The following options can be helpful for patients to rehabilitate after their fracture :

  • Joints mobilization
  • compression bandage
  • Soft tissue massage
  • Exercises and Activity modification
  • Forearm taping
  • Forearm bracing

Postoperative Rehabilitation

  • Complex Pilon fracture warrant individualized immobilization and rehabilitation strategies.
  • Because most multifragmentary Pilon fracture are the result of high-energy injuries, a prolonged period of wrist immobilization and soft-tissue rest may be beneficial and has not been shown to affect clinical outcomes.
  • The ankle is typically immobilized for 6 weeks post-operatively in a splint with Full weight bearing commences at approximately 3 months post-operatively after consolidation of the fracture is noted on radiographs.
  • The presence of varying degrees of ankle stiffness is inevitable and may result from poor pain control, lack of effort in controlled mobilization, edema, concomitant ipsilateral lower extremity fractures, or peripheral nerve injuries. Early stretching and mobilization of the intrinsic and extrinsic tendons of the hand is important to prevent finger stiffness. Edema control can be initiated with compression gloves, digital massage, and active and passive ROM of the ankle. A home exercise program or outpatient occupational therapy is started immediately post-operatively to maintain full range of motion of the ankle and limit the development of intrinsic muscle tightnes

Primary Prevention

There are various preventive options to reduce the incidence of the Pilon fracture

  • Using forearm and wrist guards during practicing sports (skating, biking)
  • Using forearm and wrist guards during driving motorbikes
  • Avoid falls in elderly individuals
  • Prevention and/or treatment of osteoporosis
  • Healthy diet

Secondary Prevention

It should be noted that the Post-menopausal women specially older than the age of 65 are at the higher risk of osteoporosis consequently these type of patients at greater risk for the pathological fractures .

So the Calcium and vitamin D supplementation play important role in increasing the bone mineral density (BMD) consequently decrease the risk of fracture in these type of patients. Also, avoiding excessive alcohol and quitting smoking play important role in this regard.
