Simple Acts of Kindness to Relieve Patient Pain

In general, doctors treat patients for pain due to injury or surgery. Pain intensity varies from person to person and it can be related to stress, distress, coping strategies, and physiological factors. The physician should work with the patient for better pain control and for safer prescribing of medications.  The best pain relief is self-efficacy and resilience. We have found that giving the patient a teddy bear helps to relieve their pain and anxiety, giving the patient comfort and confidence in the system.

Adhesive Capsulitis, Frozen Shoulder

Adhesive Capsulitis, or frozen shoulder, is a painful progressive loss of shoulder motion. It affects both active and passive movement of the shoulder joint. The shoulder will be stiff and painful and occurs due to inflammation, fibrosis, scarring, and contraction of the capsule. A normal shoulder joint capsule is elastic and allows great range of motion. Inflammation and thickening of the shoulder capsule and may lead to adhesive capsulitis. Frozen shoulder may occur without any specific cause, however it may be triggered by a mild trauma to the shoulder.

This condition develops slowly and goes through three phases:

1. Pain and freezing
2. Stiffness or frozen
3. Resolution

During the pain and freezing phase, the pain is worse at night and increases with any movement. This phase will last several months. During the second phase, range of motion is limited as pain is diminishing. This may last up to one year. The resolution phase may begin overtime and may last up to three years.

Conditions associated with frozen shoulder include:

• Diabetes
• Thyroid problems
• Auto immune disease
• Stroke
• Rheumatoid arthritis
• Trauma or post-surgery

A patient with frozen shoulder will have loss of both active (movement without assistance) and passive (movement with assistance) motion. External rotation of the shoulder is very limited and the condition is self-limiting and may resolve on its own. X-rays are needed to rule out degenerative arthritis.  An MRI or arthrogram will show small fluid in joint cavity. Rotator cuff may be normal and synovitis and narrowing of the rotator cuff interval is usually seen.

Treatment consists of anti-inflammatory medications, physical therapy, injections, and manipulation under anesthesia. Surgery will be done in the form of a release of the capsule when nonoperative methods fail. The physician should always check the patient for diabetes.  

Triplane Fracture of the Distal Tibia

A triplane fracture of the distal tibia usually occurs during adolescence and occurs before complete closure of the distal tibial physis. The distal tibial physis (growth plate) is a weak area which closes from central to medial, with the lateral side being the last part to close. A Triplane fracture is a Salter-Harris Type IV Fracture, involving all three planes, the coronal (metaphysis), transverse (growth plate), and sagittal (epiphysis). The fracture has several variations and occurs due to external rotation forces. This fracture typically occurs in patients between 12-15 years of age.

Triplane fractures are complicated three-dimensional fractures. A two-part fracture is a Salter-Harris Type IV. A Three-part fracture is a combination of Salter-Harris Type III in an AP view and a Type II in a lateral view. CT scans are helpful.

An ORIF is necessary if there is displacement of the fragments of more than 2 mm.

Intra-articular Extensile Approach for Tibial Plateau Fractures

Several types of tibial plateau fractures are a complex management problem. The knee joint may have a significant comminution and depression, and the physician may need to take an extensile approach for reduction and fixation of this fracture. Personally, I use the intra-articular extensile approach for tibial plateau fracture reduction and fixation. In general, fracture of the tibial plateau is a complicated problem.

A vascular evaluation is necessary. The ankle-brachial index (ABI) is needed in some types, such as in medial plateau fractures or in severe types, such as Schatzker Type V or Type VI. The ABI should be more than 0.9. Usually, medial tibial plateau fractures are considered to be a knee dislocation. A fasciotomy may be needed if compartment syndrome occurs. The soft tissue condition may be bad, and an external fixator may be initially used until the soft tissue condition improves.

The association between tibial plateau fractures and meniscal tear is not uncommon. A lateral plateau fracture will create a lateral meniscal tear, while the medial plateau fracture will cause a medial meniscal tear. A tear of the meniscus is usually peripheral. It should be recognized and dealt with. The physician may want to look at the x-ray and see if there is a depression or separation of more than 6mm, as this indicates a high chance of meniscal tear.

The posteromedial fragment is another problem with tibial plateau fractures which needs to be fixed separately. When an extensive comminuted displaced tibial plateau fracture occurs, the physician may need excellent exposure of the articular surface to allow for anatomic reduction of the joint and visualization and repair or debridement of the meniscus if it is torn. This extensile exposure is important, especially if the posterior part of the plateau is involved. The traditional way to see the articular cartilage of the tibial plateau is to use the submeniscal approach by cutting the coronary ligament, but the exposure is limited. Other extensile approaches are also developed; however, we use the extensile intra-articular approach for complex, comminuted tibial plateau fractures. This involves anterior detachment and retraction of the meniscus to improve visualization of the tibial articular surface. This approach can be utilized for lateral or medial tibial plateau fractures and it is especially helpful in diagnosing and repairing the torn meniscus. This allows for inspection of the meniscus pathology in fractures of the articular surface. This improves reduction of the fracture and the torn meniscus is repaired and reattached to the coronary ligament. Incision and reflection of the meniscus allows great exposure and inspection of the joint which is followed by reattachment and suturing of the anterior horn of the meniscus to its normal position which is followed by reattachment of the meniscotibial (coronary) ligament. The sutures are tied to the sides of the patellar tendon on the opposite side of the meniscus.

Isolated Fibular Fractures

Fibular fractures are usually associated with a complex injury, however they can be an isolated fracture. Complex injuries where a fibula fracture can occur include: fracture of the fibula and tibia, ankle fracture, pilon fracture, and Maisonneuve fractures.

Maisonneuve fractures involve a fracture of the proximal fibula associated with an occult injury of the ankle. Isolated fibular fractures are rare and usually the result of direct trauma. The fibula carries about 15% of the axial load and is the site of muscle attachment for the peroneus muscles and the flexor hallucis longus muscle. Check the patient who has a fibular fracture and no other fracture involving the tibia to rule out a possible Maisonneuve fracture, especially if there is no history of direct trauma to the leg. A high index of suspicion is necessary to diagnose and treat this injury. For high fibular fractures, the physician should look for signs of syndesmotic injury. Syndesmotic injury may include an unexplained increase in the medial clear space or the tibiofibular clear space is widened (should be less than 5mm). The x-ray will show the fracture to be rotational or oblique. Maisonneuve fractures require surgery to fix the syndesmosis.

Treatment will consist of reduction and fixation. It is important to determine if the injury is a Maisonneuve fracture or an isolated fibular fracture. An isolated fibular fracture will not need surgery.

Cauda Equina—Central Disc Herniation

Disc herniations usually occurs posterolaterally, but it may also be central. The cauda equina is composed of several nerves within the lower end of the spinal canal. The top of the spinal cord is a tubular bundle of nervous tissue extending from the brain.

The following section of the spinal cord is called the Conus Medullaris and is the lower end of the spinal cord. The Cauda Equina is made up of multiple nerve roots beginning at the level of L1.

The most common disc herniation is the Posterolateral Disc Herniation. This type of herniation is a nerve root injury, which will cause changes to both the sensory and motor skills as well as the reflexes. A posterolateral disc herniation usually affects the foot and ankle, and may cause unilateral leg pain and weakness. Observe for a positive straight leg raising test. These herniations are usually initially treated with conservative methods.  

A central disc herniation will cause cauda equina syndrome, which is a compression over the lumbosacral nerve roots. This compression will cause more back pain than leg pain, and bladder and bowel symptoms will be evident. This herniation is considered a surgical emergency.

Malunions of the Clavicle

It is difficult to reduce and maintain the reduction of clavicle fractures as there will be deforming forces in the midshaft area of the clavicle. The clavicle will heal regardless as to if a sling or figure 8 strap is used. Despite the presence of a bump, fracture displacement, and deformity, healing of the fracture still occurs rapidly. Healing occurs in about 85% of cases, however, the clavicle will not look aligned due to the difficulty in reducing the fracture. It is hard to achieve a reduction of these fracture without surgery. Without surgical reduction, the fracture may end with some degree of malunion and possible shortening of the clavicle. The fragments will not line up with the distal fragment appearing to be downward and anteriorly rotated. Shortening is clinically significant because it alters the dynamics of the muscles around the shoulder. It also narrows the costoclavicular space. The patient may complain of decreased shoulder strength and endurance if the patient had a displaced midshaft clavicle fracture that healed with more than 2 cm of shortening.

What are the symptoms of clavicle malunion?

Pain, easy fatigability, cosmetic problems (especially in females), neurological dysfunction (possible involvement of the brachial plexus—especially the ulnar nerve), and the patient may have thoracic outlet syndrome.

X-rays should be done of both shoulders. Bilateral panoramic views are beneficial in order to measure the shortening. The physician will also want to check the amount of overlap at the ends of the clavicle.

Treatment

Surgical treatment of the malunion may be successful in restoring the function and relieving the pain. A clavicle osteotomy is done in the plane of the healed fracture. The fracture is recreated with correction of the deformity and the length of the clavicle is restored. A local or iliac crest bone graft can be used if needed.

If an osteotomy is done with reduction of the clavicle to its preinjury position and leaves a significant bone defect, the physician will need a tricortical piece of bone at the osteotomy area. It is probably better to use a precontoured clavicle plate in the superior position with six cortices, three placed on each side of the osteotomy.

Elbow Joint Dislocations

An Elbow dislocation occurs when the radius and ulna bones of the forearm move out of place from the humerus bone of the upper arm. There are two basic types of elbow dislocations:

1. Simple

   No fracture of the bones around the elbow joint

   Usually ligamentous injury

2. Complex

   Fracture has occurred along with ligamentous injury

Simple elbow dislocations typically occur when the patient falls onto an outstretched hand. Injury progression from lateral to medial in most patients. Posterolateral simple dislocations are the most common, occurring approximately 90% of the time.

The proximal ulna and radius are displaced posterolaterally relative to the distal humerus. Postemedial dislocations occur at the proximal ulna and radius and are displaced posteromedially relative to the distal humerus. In medial dislocations, the proximal ulna and radius are displaced medially relative to the distal humerus. With lateral dislocations, the proximal ulna and radius are displaced laterally relative to the distal humerus. Anterior dislocations are rare, as they result from a direct force applied to the posterior aspect of the forearm with the elbow in a flexed position. Anterior dislocations occur when the proximal ulna and radius are displaced anteriorly relative to the distal humerus. If stable, simple acute fractures can be treated with a closed reduction and a splint for two to three days (no more than two weeks) in addition to range-of-motion exercises and physical therapy. Unstable simple fractures are rare, but can be stabilized by ligament repair and/or by the use of an external fixator or cross pinning of the joint in the elderly.

Chronic Elbow dislocations will need to be treated with an open reduction and external fixator and is usually hinged. Recurrent elbow dislocations (diagnosed by pivot shift) occurs due to a deficiency of the lateral collateral ligament and is treated by a reconstruction of the ulnohumeral ligament with a tendon graft.

Clay Shoveler’s Fracture

A clay shoveler’s fracture is a stable fracture through the spinous process of the vertebra C6-T1 and typically occurs at the level of C6 or C7. Clay shoveler’s fracture gets its name from the common injury suffered by men diffing deep ditches in Australia during the 1930s.

Powerful hyperflexion of the neck combined with contraction of the paraspinous muscles during shoveling is the typical mechanism of injury. The tremendous force pulls on the spinous process, producing an avulsion fracture.

The fracture is best seen on a lateral view x-ray. There will be a ghost sign on AP view x-rays—double spinal process of C6 or C7, resulting from a displaced fractured spinous process.

Stable fractures can be treated nonoperatively, utilizing a collar and physical therapy.

Pronator Teres Syndrome

The nerve that is involved in pronator teres syndrome is the median nerve. Pronator Teres Syndrome is caused by a compression of the median nerve at the level of the elbow which occurs more in women. In the forearm, the median nerve runs between the two heads of the pronator teres muscle and then it lies between the flexor digitorum superficialis and flexor digitorum profundus muscles. This syndrome may be associated with medial epicondylitis. The principle symptoms of numbness in the radial 3 ½ fingers as well as thenar weakness which may be mistakenly attributed to carpal tunnel syndrome.

The most common cause of entrapment is due to compression of the median nerve between the two heads of the pronator teres muscle. This commonly occurs in people who perform repetitive forceful pronation of the forearm. Compression may be due to the thickening of the bicipital aponeurosis. The aponeurosis crosses from lateral to medial over the antecubital fossa and may irritate the median nerve. Compression of the nerve may also occur due to the fibrous arch of the origin of the flexor digitorum superficialis (FDS).

The median nerve runs down the medial side of the arm and passes 2 ½ to 4 cm below the level of the medial epicondyle before it enters between the two heads of the pronator teres. About 1% of

patients have a medial supracondylar humeral spur about 5cm proximally to the medial epicondyle. The ligament of Struthers is attached to this bony projection which connects the process to the medial epicondyle. The bony process points towards the elbow joint and the median nerve can become compressed by the supracondylar spur. The median nerve can also become trapped by the ligament of Struthers that extends from the supracondylar process to the medial epicondyle. The ligament of Struthers is different from the arcade of Struthers, which deals with the compression of the ulnar nerve around the elbow.

Paresthesia in these lateral 3 ½ fingers may occur with the compression of the median nerve at the elbow region or at the carpal tunnel region. These symptoms are similar to carpal tunnel syndrome but the symptoms are worse with rotation of the forearm. The patient will complain of dull aching pain over the proximal forearm with no nighttime symptoms. The pain is usually worsened by repetitive or forceful pronation. Tenderness of palpation to the pronator teres muscle will be detected. The median nerve gives off a palmar cutaneous branch before entering the carpal tunnel. Sensory disturbances over the palm of the hand occur due to involvement of the palmar cutaneous branch of the medial nerve and this occurs proximal to the carpal tunnel. Sensory disturbances in this area indicates median nerve problems proximal to the carpal tunnel. This differentiates between carpal tunnel syndrome and pronator teres syndrome.

There are specific provocative tests that produce the pain and distal paresthesia that are used to localize the site of compression. The Tinel’s sign at the wrist and the Phalen’s test will be negative. The Median nerve compression tests are negative at the carpal tunnel; however, there will be a positive Tinel’s sign at the proximal forearm. There will be abnormal sensation in the “palmar triangle”. When compression of the nerve involves the supracondylar process, the test is considered positive if symptoms of tingling worsen while tapping on the spur.

Occassionally, the spur can be felt. The pronator teres muscle can be assessed as the cause of the median nerve compression in different ways. Resisted forearm pronation with elbow flexion will test for compression at the two heads of the pronator teres muscle. During this test, the patient’s forearm is held in resisted pronation and flexion. While remaining in a pronated position, the forearm is gradually extended. Compression of the median nerve may also be tested by: resisted elbow flexion with forearm supination (compression at the bicipital aponeurosis) and resisted contraction of the FDS to the middle finger (compression at the FDS arch).

Differential Diagnosis

C6/C7 Radiculopathy occurs due to involvement of the nerves at these levels which will cause numbness of the thumb, index, and long fingers, as well as weakness of the muscles of the forearm that are innervated by the median nerve. The radial nerve part of C6-C7 will show normal function of the wrist extensors and the triceps.

X-rays, imaging and nerve conduction studies may be helpful in the diagnosis.

Treatment typically consists of rest, splints, and NSAIDs. Surgical decompression of the median nerve through all 4 or 5 possible sites of compression when non-operative management fails for 3-6 months. The results of surgery are variable. Full recovery is not always seen in all patients as only about 80% of patients improve from surgery. The skin incision may leave an unsatisfactory scar.

PIP Dorsal Fracture Dislocation

Proximal interphalangeal (PIP) dorsal fracture dislocations can be challenging in management. In PIP dorsal fracture dislocations, there is an involvement of the articular surfaces of the joint. These injuries are the most disabling PIP joint injuries. A reduction of the middle phalanx on the condyles of the proximal phalanx is the primary goal of treatment. The patient frequently presents with a chronic dorsal subluxation due to delay in seeking treatment or from failed treatment.

85% of motion for grasping objects occurs at the PIP joint. The PIP joint has the largest arc of motion (120 degrees) of the three joints in each digit.

There are three different types of injury:

1. Hyperextension
2. Impact Shear
3. Pylon

In cases of Hyperextension injuries, the size of the fragment can range from a small piece of bone, up to 30% of the joint surface with minimal comminution (usually stable).  In order to provide accurate treatment, the physician will want to test the stability of the fracture and apply a dorsal blocking splint. It is important to observe the lateral view for any subluxation.

Impaction/Shear injuries are produced by an axial load applied to a slightly extended or flexed PIP joint. The middle phalanx is driven over the head of the proximal phalanx with comminution and impaction of the base of the middle phalanx. These injuries are characterized by the loss of the volar plate tether. A 50% loss of the palmar of the middle phalanx base will make the PIP joint unstable. The extensor tendon and superficialis tendon will aggravate the dorsal subluxation. Splints will be inadequate if the injury is not stable. Treatment will include skeletal traction and early range of motion. An open reduction and internal fixation may be necessary if the fragment is large enough. A Palmar Plate Arthroplasty may be considered to advance the palmar plate into the defect. This procedure will support the palmar plate by filling the defect behind it with fracture chips, bone graft, or by a superficialis slip. Chronic impaction/shear cases are a difficult problem and can be treated with an arthrodesis or volar plate arthroplasty.

A pylon fracture results from an axial force that fractures the volar and dorsal articular surfaces with impaction on the central part. A pylon fracture is not a true fracture dislocation and will not have a good outcome. Dynamic external traction should be done in order to help in ligamentotaxis. Early range of motion is important for remodeling of the joint.

Classification of a PIP Dorsal Fracture Dislocation will depend on the degree of involvement of the articular surface.

• Type I (stable) <30%
• Type II (tenuous)= 30-50%
• Type III (unstable) > 50%

Treatment will consist of a Dorsal Extension Blocking Splint if the PIP can be reduced in less than 30% of flexion. If less than 40%, the joint involved and stable. For Type I and Type II fractures, decrease the flexion gradually every week. Type III fractures will require ORIF, volar plate arthroplasty, or hemi-hamate graft (if >40% joint involved and unstable).

With a Hemi-Hamate Graft, the damaged palmar lip of the middle phalanx with a size matched portion of the hamate bone obtained from its distal dorsal articular surface between the 4^th and 5^th metacarpals. It restores both articular congruity and osseous stability. Extension block pinning is probably a helpful technique. Treatment must provide stable reduction to allow for early mobilization.

Stability of the reduction depends on the size of the avulsed fragment and the amount of ligament remaining attached to the middle phalanx. If less than 40% of the articular segment is avulsed, some of the collateral ligament will be intact. This will keep the reduction stable. If more than 40% of the articular segment has avulsed, only very little or none of the ligament will remain attached to the base of the middle phalanx, rendering the reduction unstable.

Recognizing Subluxation

AP and lateral x-rays are necessary for diagnosis. An AP view will help to recognize impaction fractures.  Subluxation can be missed on x-rays. The physician will want to look for the characteristic “V” sign of diverging joint surfaces, which indicates injury and subluxation.

If a reduction of the avulsion fracture is achieved with less than a 30 degree bend, nonoperative treatment is a good choice. However, if it takes more than 30 degrees of flexion to reduce the fragment, this may be an indication for surgery.
