It can develop as a result of the normal wear-and-tear on the joint. Sprains and injuries to the foot, abnormal foot biomechanics and deformities can also cause osteoarthritis to develop. Osteophytes Bone Spurs Bone spurs are bony growths or projections that can develop along joints. They are often associated with osteoarthritis. They can cause pain and result in limitations to the movement of the joints they affect.
We often take our feet for granted until an injury or arthritis forces us to see how dependent we are on their normal function. If you have any discomfort which is severe or persists, make sure to make an appointment to see your healthcare provider or podiatrist earlier rather than later.
Many foot conditions are much easier to treat when they haven't become a chronic problem. Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life. Kasper, Dennis L.. Fauci, and Stephen L.. Harrison's Principles of Internal Medicine.

Two sesamoid bones are often present present on the plantar aspect of the MTP joint of the great toe, of which the medial is the larger sesamoid see multipartite hallux sesamoid.
Sesamoid bones can also be found at the MTP joints of the second to fifth toes, and the IP joint of the great toe 2. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Updating… Please wait.

Abnormal appendicular skeleton morphology Abnormality of limb bone morphology Abnormality of digit Abnormality of toe Abnormality of the phalanges of the toes Abnormality of toe proximal phalanx Short proximal phalanx of toe. Recent clinical studies. Epub Jan 8 doi: PMID: Epub Oct 11 doi: Although tendon injuries may accompany a toe fracture, they are uncommon.
Physical examination should include assessment of capillary refill; delayed capillary refill may indicate circulatory compromise. The skin should be inspected for open wounds or significant injury that may lead to skin necrosis. The nail should be inspected for subungual hematomas and other nail injuries. Deformity of the digit should be noted; most displaced fractures and dislocations present with visible deformity. Nondisplaced fractures usually are less apparent; however, most patients with toe fractures have point tenderness over the fracture site.
The localized tenderness of a contusion may mimic the point tenderness of a fracture. Application of a gentle axial loading force distal to the injury i. If this maneuver produces sharp pain in a more proximal phalanx, it suggests a fracture in that phalanx.
Radiographic studies of a toe should include anteroposterior, lateral, and oblique views Figure 1. A combination of anteroposterior and lateral views may be best to rule out displacement. However, overlying shadows often make the lateral view difficult to interpret Figure 1 , center. In many cases, anteroposterior and oblique views are the most easily interpreted Figure 1 , top and bottom. Radiographic series showing spiral fracture of the proximal phalanx of the fourth toe.
Note that this patient has an anatomic variant—the fifth toe has only two phalanges. Left Antero-posterior view. Angulation, shortening, and slight rotation are visible. Two normal sesamoid bones can be seen beneath the first metatarsal head. Center Lateral view. Overlying shadows make it difficult to discern the fourth toe and detect the mildly displaced fracture. Right Oblique view. Unlike the lateral view, this view clearly shows the fracture.
It also provides another perspective to assess the degree of displacement. Fractures of the lesser toes are four times as common as fractures of the first toe. Comminution is common, especially with fractures of the distal phalanx. Displaced spiral fractures generally display shortening or rotation, whereas displaced transverse fractures may display angulation. In children, toe fractures may involve the physis Figure 2.
Displaced Salter-Harris type II frac ture of the proximal phalanx of a child's fifth toe Physis can be seen in the proximal aspect of the other phalanges. Fractures of multiple phalanges are common Figure 3. Therefore, phalanges and digits adjacent to the fracture must be examined carefully; joint surfaces also must be examined for intra-articular fractures Figure 3.
Patients with intra-articular fractures are more likely to develop long-term complications. Nondisplaced transverse fracture of the proximal phalanx of the fourth toe, with a subtle intra-articular fracture of the proximal phalanx of the fifth toe.
Without careful scrutiny of adjacent digits, the more problematic intra-articular fracture could be missed. Patients with circulatory compromise require emergency referral. Toe fractures of this type are rare unless there is an open injury or a high-force crushing or shearing injury.
Patients with open toe fractures or fractures with overlying skin necrosis are at high risk for osteomyelitis. If there is a break in the skin near the fracture site, the wound should be examined carefully. If the wound communicates with the fracture site, the patient should be referred. In some practice sites, family physicians manage open toe fractures; a discussion about the management of this type of injury can be found elsewhere.
