Galeazzi fractures are best treated with open reduction of the radius and the distal radio-ulnar joint. It has been called the "fracture of necessity," because it necessitates open surgical treatment in the adult. Nonsurgical treatment results in persistent or recurrent dislocations of the distal ulna. However, in skeletally immature patients such as children, the fracture is typically treated with closed reduction.

It is sometimes possible to correct the problem with surgery, though this has high failure rates for treatment of post-traumatic radioulnar synostosis.

Non-surgical interventions include three elements: weight control, exercise control, and medication. Canine massage may alleviate discomfort and help move lymph and nutrients through the system. Weight control is often "the single most important thing that we can do to help a dog with arthritis", and consequentially "reducing the dog's weight is enough to control all of the symptoms of arthritis in many dogs". Reasonable exercise stimulates cartilage growth and reduces degeneration (though excessive exercise can do harm too), and also regular long walks in early or mild dysplasia can help prevent loss of muscle mass to the hips. Medication can reduce pain and discomfort, and also reduce damaging inflammation.

Non-surgical intervention is usually via a suitable non-steroidal anti-inflammatory drug (NSAID) which doubles as an anti-inflammatory and painkiller. Typical NSAIDs used for hip dysplasia include carprofen and meloxicam (often sold as Rimadyl and Metacam respectively), both used to treat arthritis resulting from dysplasia, although other NSAIDs such as tepoxalin (Zubrin) and prednoleucotropin ("PLT", a combination of cinchophen and prednisolone) are sometimes tried. NSAIDs vary dramatically between species as to effect: a safe NSAID in one species may be unsafe in another. It is important to follow veterinary advice.

A glucosamine-based nutritional supplement may give the body additional raw materials used in joint repair. Glucosamine can take 3–4 weeks to start showing its effects, so the trial period for medication is usually at least 3–5 weeks. In vitro, glucosamine has been shown to have negative effects on cartilage cells.

It is also common to try multiple anti-inflammatories over a further 4–6 week period, if necessary, since an animal will often respond to one type but fail to respond to another. If one anti-inflammatory does not work, a vet will often try one or two other brands for 2–3 weeks each, also in conjunction with ongoing glucosamine, before concluding that the condition does not seem responsive to medication.

Carprofen, and other anti-inflammatories in general, whilst very safe for most animals, can sometimes cause problems for some animals, and (in a few rare cases) sudden death through liver toxicity. This is most commonly discussed with carprofen but may be equally relevant with other anti-inflammatories. As a result, it is often recommended to perform monthly (or at least, twice-annually) blood tests to confirm that the animal is not reacting adversely to the medications. Such side effects are rare but worth being aware of, especially if long-term use is anticipated.

This regimen can usually be maintained for the long term, as long as it is effective in keeping the symptoms of dysplasia at bay.

Some attempts have been made to treat the pain caused by arthritic changes through the use of "laser therapy", in particular "class IV laser therapy". Well-controlled clinical trials are unfortunately lacking, and much of the evidence for these procedures remains anecdotal.

Most temporomandibular disorders (TMDs) are self-limiting and do not get worse. Simple treatment, involving self-care practices, rehabilitation aimed at eliminating muscle spasms, and restoring correct coordination, is all that is required. Nonsteroidal anti inflammatory analgesics (NSAIDs) should be used on a short-term, regular basis and not on an as needed basis. On the other hand, treatment of chronic TMD can be difficult and the condition is best managed by a team approach; the team consists of a primary care physician, a dentist, a physiotherapist, a psychologist, a pharmacologist, and in small number of cases, a surgeon. The different modalities include patient education and self-care practices, medication, physical therapy, splints, psychological counseling, relaxation techniques, biofeedback, hypnotherapy, acupuncture, and arthrocentesis.

As with most dislocated joints, a dislocated jaw can usually be successfully positioned into its normal position by a trained medical professional. Attempts to readjust the jaw without the assistance of a medical professional could result in worsening of the injury. The health care provider may be able to set it back into the correct position by manipulating the area back into its proper position. Numbing medications such as general anesthetics, muscle relaxants, or in some cases sedation, may be needed to relax the strong jaw muscle. In more severe cases, surgery may be needed to reposition the jaw, particularly if repeated jaw dislocations have occurred.

There is no complete cure, although there are many options to alleviate the clinical signs. The aim of treatment is to enhance quality of life. Crucially, this is an inherited, degenerative condition and so will change during the life of an animal, so any treatment is subject to regular review or re-assessment if the symptoms appear to get worse or anything significantly changes.

If the problem is relatively mild, then sometimes all that is needed to bring the symptoms under control are suitable medications to help the body deal better with inflammation, pain and joint wear. In many cases this is all that is needed for a long time.

If the problem cannot be controlled with medications, then often surgery is considered. There are traditionally two types of surgery - those which reshape the joint to reduce pain or help movement, and hip replacement which completely replaces the damaged hip with an artificial joint, similar to human hip replacements.

Some studies suggest a hormonal link. Specifically, the hormone relaxin has been indicated.

A genetic factor is indicated since the trait runs in families and there is an increased occurrence in some ethnic populations (e.g., Native Americans, Lapps / Sami people). A locus has been described on chromosome 13. Beukes familial dysplasia, on the other hand, was found to map to an 11-cM region on chromosome 4q35, with nonpenetrant carriers not affected.

If intraarticular trapeziometacarpal fractures (such as the Bennett or Rolando fractures) are allowed to heal in a displaced position, significant post-traumatic osteoarthritis of the base of the thumb is virtually assured. Some form of surgical treatment (typically either a CRPP or an ORIF) is nearly always recommended to ensure a satisfactory outcome for these fractures, if there is significant displacement.

The long-term outcome after surgical treatment appears to be similar, whether the CRPP or the ORIF approach is used. Specifically, the overall strength of the affected hand is typically diminished, and post-traumatic osteoarthritis tends to develop in almost all cases. The degree of weakness and the severity of osteoarthritis does however appear to correlate with the quality of reduction of the fracture. Therefore, the goal of treatment of Bennett fracture should be to achieve the most precise reduction possible, whether by the CRPP or the ORIF approach.

Jaw dislocation is common for people who are in car, motorcycle or related accidents and also sports related activities. This injury does not pin point specific ages or genders because it could happen to anybody. People who dislocate their jaw do not usually seek emergency medical care. In most cases, jaw dislocations are acute and can be altered by minor manipulations. It was reported from one study that over a seven-year period at an emergency medical site, with 100,000 yearly visits, there were only 37 patients that were seen for a dislocated jaw.

The incidence of Hill–Sachs lesion is not known with certainty. It has been reported to be present in 40% to 90% of patients presenting with anterior shoulder instability, that is subluxation or dislocation. In those who have recurrent events, it may be as high as 100%. Its presence is a specific sign of dislocation and can thus be used as an indicator that dislocation has occurred even if the joint has since regained its normal alignment. The average depth of Hill–Sachs lesion has been reported as 4.1 mm. Large, engaging Hill-Sachs fractures can contribute to shoulder instability and will often cause painful clicking, catching, or popping.

The etiology of the Galeazzi fracture is thought to be a fall that causes an axial load to be placed on a hyperpronated forearm. However, researchers have been unable to reproduce the mechanism of injury in a laboratory setting.

After the injury, the fracture is subject to deforming forces including those of the brachioradialis, pronator quadratus, and thumb extensors, as well as the weight of the hand. The deforming muscular and soft-tissue injuries that are associated with this fracture cannot be controlled with plaster immobilization.

The radial head fracture is usually managed by open reduction internal fixation; if the fracture is too comminuted, a radial head implant can be used. Excision of the radial head should be avoided, as the radius will migrate proximally leading to wrist pain and loss of pronation and supination of the wrist. Delayed treatment of the radial head fracture will also lead to proximal migration of the radius.

The distal radio-ulnar joint dislocation can be reduced by supination of the forearm, and may be pinned in place for 6 weeks to allow healing of the interosseous membrane.

Though these fractures commonly appear quite subtle or even inconsequential on radiographs, they can result in severe long-term dysfunction of the hand if left untreated. In his original description of this type of fracture in 1882, Bennett stressed the need for early diagnosis and treatment in order to prevent loss of function of the thumb CMC joint, which is critical to the overall function of the hand.

- In the most minor cases of Bennett fracture, there may be only small avulsion fractures, relatively little joint instability, and minimal subluxation of the CMC joint (less than 1 mm). In such cases, closed reduction followed by immobilization in a thumb spica cast and serial radiography may be all that is required for effective treatment.

- For Bennett fractures where there is between 1 mm and 3 mm of displacement at the trapeziometacarpal joint, closed reduction and percutaneous pin fixation (CRPP) with Kirschner wires is often sufficient to ensure a satisfactory functional outcome. The wires are not employed to connect the two fracture fragments together, but rather to secure the first or second metacarpal to the trapezium.

- For Bennett fractures where there is more than 3 mm of displacement at the trapeziometacarpal joint, open reduction and internal fixation (ORIF) is typically recommended.

Regardless of which approach is employed (nonsurgical, CRPP, or ORIF), immobilization in a cast or thumb spica splint is required for four to six weeks.

Hip dysplasia is considered to be a multifactorial condition. That means that several factors are involved in causing the condition to manifest.

The cause of this condition is unknown; however, some factors of congenital hip dislocation are through heredity and racial background. It is also thought that the higher rates in some ethnic groups (such as some Native American groups) is due to the practice swaddling of infants, which is known to be a potential risk factor for developing dysplasia. It also has a low risk in African Americans and southern Chinese.

A cubitus varus deformity is more cosmetic than limiting of any function, however internal rotation of the radius over the ulna may be limited due to the overgrowth of the humerus. This may be noticeable during an activity such as using a computer mouse.

Future research with regard to medial knee injuries should evaluate clinical outcomes between different reconstruction techniques. Determining the advantages and disadvantages of these techniques would also be beneficial for optimizing treatment.

The Essex-Lopresti fracture is a fracture of the radial head with concomitant dislocation of the distal radio-ulnar joint and disruption of the interosseous membrane. The injury is named after Peter Essex-Lopresti who described it in 1951.

A burst fracture is a type of traumatic spinal injury in which a vertebra breaks from a high-energy axial load (e.g., traffic collisions or falls from a great height or high speed, and some kinds of seizures), with shards of vertebra penetrating surrounding tissues and sometimes the spinal canal. The burst fracture is categorized by the ""severity of the deformity, the severity of" (spinal) "canal compromise, the degree of loss of vertebral body height, and the degree of neurologic deficit."" Burst fractures are considered more severe than compression fractures because long-term neurological damage can follow. The neurologic deficits can reach their full extent immediately, or can progress for a prolonged time.

The decisions involved in the repair of the Hill–Sachs lesion are complex. First, it is not repaired simply because of its existence, but because of its association with continuing symptoms and instability. This may be of greatest importance in the under-25-year-old and in the athlete involved in throwing activities. The Hill-Sachs role in continuing symptoms, in turn, may be related to its size and large lesions, particularly if involving greater than 20% of the articular surface, may impinge on the glenoid fossa (engage), promoting further episodes of instability or even dislocation. Also, it is a fracture, and associated bony lesions or fractures may coexist in the glenoid, such as the so-called bony Bankart lesion. Consequently, its operative treatment may include some form of bony augmentation, such as the Latarjet or similar procedure. Finally, there is no guarantee that associated non-bony lesions, such as a Bankart lesion, SLAP tear, or biceps tendon injury, may not be present and require intervention.

Most commonly due to anterior shoulder dislocation caused by hyperabduction and external rotation of the arm. Usually in young men who play contact sports (E.g. rugby, football, volleyball, basketball, etc.). Frequent anterior (frontward) subluxation also poses a great risk factor.

Humeral avulsion of the glenohumeral ligament (HAGL) is defined as an avulsion (tearing away) of the inferior glenohumeral ligament from the anatomic neck of the humerus. In other words, it occurs when we have disruption of the ligaments that join the humerus to the glenoid.

HAGL tends to occur in 7.5-9.3% of cases of anterior shoulder instability. Making it an uncommon cause of anterior shoulder instability.

Avulsion of this ligamentous complex may occur in three sites: glenoid insertion (40%), the midsubstance (35%) and the humeral insertion (25%).

Immediate hospitalization is required, as such injuries may result in varying degrees of spinal cord injury with possible paralysis. X-rays and MRIs are taken to determine whether the burst fracture can be managed with or without surgery. Surgical management is required when the burst fracture is unstable. Predicting spinal instability of vertebral thoracic lumbar fractures is based on several radiologic and clinical parameters. Efforts to refine fracture classification schemes to better predict instability continue. Application of axial zone model proposed by physicians at Barrow Neurological Institute may enhance the ability to predict stability, depending not only on the number of columns, but also on the number of zones involved in the injuries. Further clinical and biomechanical studies are warranted to validate this model.

Different surgical treatments are available, the most common involving fusion of the remaining vertebra in the traumatized area, and removal of the larger loose vertebra pieces. A "spinal fusion" surgery entails two or more vertebra are permanently immobilized through surgery using titanium implants. Another less common technique is to replace the burst vertebra with an artificial bone or cadaver bone. Both latter strategies have been used successfully in elderly subjects, and has not yet been attempted in younger subjects due to the unknown stability over the long term.

Nonsurgical management is possible when the burst fracture subject is intact neurologically. Nonsurgical treatment involves the use of a full-body, exterior brace, normally a thoracic lumbar sacral orthosis (TLSO), often custom-molded to the subject's body. X-rays and MRIs are again taken with the subject every 2 weeks in the TLSO to determine whether the spine will remain stable. The TLSO is worn for 2–3 months 24/7. The subject undergoes several months of physical therapy to strengthen atrophied muscles and basically learn how to walk again. It is probable that the subject may exhibit some spinal dislocation after removal of the TLSO, and it is well within expected parameters with little neurological impact experienced by month 3. If no further major dislocation or subluxation occurs, no other external stabilization may be required.

Specific populations at high risk of primary PFPS include runners, bicyclists, basketball players, young athletes and females.

Post-traumatic cases are most likely to develop following surgery for a forearm fracture, this is more common with high-energy injuries where the bones are broken into many pieces (comminuted). It can also develop following soft tissue injury to the forearm where there is haematoma formation.

Cubitus varus is not able to be diagnosed until after healing of the prior fracture, as the arm must be in full extension, not flexion, for the deformity to be noticed.

First options for treatment are conservative, using hot or cold packs, rest and NSAID's at first. If no improvement is made, a splint or brace can be used to keep the deviated arm straight. When none of the conservative treatments work surgical intervention is designated.
