Torus fracture:A cortical deformity caused by compression and is usually metaphyseal in loca- tion order hydrochlorothiazide 25mg with amex. Lead pipe fracture: An incomplete transverse fracture of one cortex with an associated buckling of the opposite side order hydrochlorothiazide 12.5 mg on-line. Plastic bowing fracture: Occurs as a result of deformation forces exceeding the elastic strain capability of the bone hydrochlorothiazide 25mg discount. Although an obvious fracture may not be generated hydrochlorothiazide 25mg generic, the bone appears bowed (bent) throughout its length hydrochlorothiazide 25 mg lowest price. Toddler’s fracture:A non-displaced oblique fracture, usually of the tibial shaft, that typically is only seen on one radiographic projection. It occurs in children between the ages of 1 and 3 years and is thought to be a result of the torsional forces that occur when the young child grips the floor with their toes when learning to walk. The epiphyses The epiphyses are the secondary ossification centres related to bone growth. Epi- physeal injuries result from shearing forces directed through the epiphyseal plate, avulsive forces focused through the ligamentous and joint capsular attach- ments and vertical forces directed to the centre of the epiphysis. Accurate iden- tification of an epiphyseal injury is essential because of its association with bone growth disturbances and possible failure of the bone to form the correct shape or joint relationships2. Bone Physeal growth Humerus Proximal = 80% Distal = 20% Radius Proximal = 25% Distal = 75% Ulna Proximal = 20% Distal = 80% Femur Proximal = 30% Distal = 70% Tibia Proximal = 55% Distal = 45% Most epiphyseal injuries occur between the ages of 10 and 16 years (with the exception of the distal humeral epiphysis where most injuries are noted in chil- dren under 10 years of age). The likelihood of an epiphyseal injury adversely affecting bone growth is dependent upon its type and site, as the rate of physeal growth is not consistent within the body (Table 7. The most commonly used system for classifying physeal fractures is the Salter-Harris classification system (Table 7. The management of physeal injuries varies from simple immobilisation to complex surgical procedures. Essentially, Salter-Harris type I and type II injuries will retain an intact epiphysis and can be treated by closed immobilisation fol- lowing minimal reduction. Salter-Harris type III and type IV injuries may require surgical intervention as the epiphyseal fragments are separate and mobile. Salter- Harris type V injuries cannot be treated directly as these injuries result from physeal compression and the subsequent closure of the growth plate prevents further growth. In these patients, regular growth assessment will be necessary to evaluate any limb length discrepancy. Upper limb injuries The clavicle The fracture and dislocation of the clavicle is a frequent childhood shoulder injury, particularly in children under 10 years of age. The injury pattern is typi- cally a greenstick fracture of the middle third of the clavicle with no associated ligamentous damage (Fig. Occasionally, in 5% of injuries, a fracture of the outer third of the clavicle may be seen and any displacement at this site is sug- gestive of coracoclavicular ligamentous damage. The coracoclavicular and acromioclavicular ligaments hold the clavicle in position and damage to these ligaments can result in clavicular subluxation or dislocation2 (Box 7. Salter-Harris type Features Diagram I Separation of the metaphysis and epiphysis which is seen radiographically as misalignment or widening of the physis Accounts for 6–8% of injuries and is most commonly seen in children under 5 years of age II Separation of physis (with or without misalignment) plus a metaphyseal fracture Commonest fracture pattern and accounts for 70% of injuries Most frequently seen in distal radius injuries and in children over 8 years of age III An intra-articular fracture through the epiphysis which results in a separated epiphyseal fragment Accounts for 7% of injuries and is commonly seen in the distal femoral and tibial epiphyses IV An intra-articular fracture through the epiphysis, physeal plate and metaphysis Accounts for approximately 12% of injuries and is most frequently seen in the lateral condyle of the humerus V Compression of the physis which has serious prognostic consequences This is the most serious physeal injury and accounts for 0. It is most commonly seen in the distal tibia and femur but can be difficult to identify, particularly after fusion across the physis has begun in adolescence 134 Paediatric Radiography Fig. Type 1: Spraining of the acromioclavicular ligaments with no movement of the clavicle. Type 2:T earing of the acromioclavicular ligaments with coracoclavicular ligaments remaining intact. Minimal malalignment may be seen with displacement of the acromioclavicular joint of up to half the thickness of the clavicle. Type 3:T earing of both the acromioclavicular and the coracoclavicular ligaments with possible associated avulsion of the coracoid process. The acromioclavicular joint is widened and the clav- icle is seen above the level of the acromion process. The scapula The scapula is rarely fractured owing to its thick covering of muscles and there- fore significant force is necessary to cause injury (e. The secondary ossification centres on the lateral aspect of the acromion can cause confusion and it is important to remember that they do not appear until between the ages of 15 and 18 years and can be fragmented in appearance. The glenohumeral joint Dislocation at the glenohumeral joint is rare in children as the proximal humeral growth plate forms a natural line of weakness and will transmit any force to gen- erate a Salter-Harris type injury. However, if a true dislocation does occur, it is likely to be in an anterior direction (97% of cases) following a fall on an out- stretched hand. Humeral shaft fractures will commonly occur following direct trauma and may have an asso- ciated open wound whereas transverse, oblique and spiral fractures are gener- ated by indirect forces.

Fibrous dysplasia is a sporadically occurring benign bone dysplasia in which fibro-osseous tissue begins replacing the interior of bones and may also affect extraskeletal sites trusted hydrochlorothiazide 25 mg. It is likely that a failure of conversion woven into lamellar bone exists buy cheap hydrochlorothiazide 25 mg on line. It is commonly seen in three different forms: a monostotic (single bone) type hydrochlorothiazide 25mg on-line, a polyostotic monomelic type in which multiples bones within a given extremity are involved cheap hydrochlorothiazide 25 mg amex, and a polyostotic generalized form that is commonly associated with precocious puberty (Albright’s disease) cheap hydrochlorothiazide 25 mg on-line. Although etiology is unknown, primitive fibrous tissue begins replacing the medullary cavity, expanding the bone from within. The disorder affects both long bones and flat bones, and, not uncommonly, the bones of the skull Miscellaneous disorders 136 and face are involved. Clinical findings depend on the location within the bone or bones, and the presence of fracturing. Pain, limping, bowing, and shortening are the usual symptoms encountered. Because of the markedly disturbed and weakened internal architecture of the long bones, fracturing is common. Cafe-au-lait spots are often seen in´ association, and have an irregular margin unlike those seen in neurofibromatosis. The presence of sexual precosity is most common in females and is quite striking in nature. Characteristically on standard radiographs the lesions of fibrous dysplasia produce a “ground glass” consistency (Figure 6. Although the location is generally metaphyseal, the lesions tend to spread into the diaphysis, producing expansion of the cortex and increasing deformity. Characteristically a “shepherd’s crook” deformity occurs in the Figure 6. Anteroposterior radiograph showing characteristic changes upper end of the femur and is quite within the tibia and fibula of fibrous dysplasia. Anteroposterior radiograph showing characteristic “shepherd’s during the period of growth, progression is crook” deformity seen in fibrous dysplasia. There is little risk of malignancy, as malignant transformation has been estimated as less than one half of one percent. Appropriate orthopedic referral is indicated once the diagnosis is established. Most patients will develop problems relative to the bony involvement such as angular deformity, scoliosis, and limb length inequality. Pathologic fractures are managed in a conventional orthopedic fashion and healing is to be anticipated. Hemangiomatosis and lymphangiomatosis Hemangiomatosis and lymphangiomatosis are hamartomatous lesions of primarily the deep soft tissues that by their presence affect the size, shape, and length of the limbs. The lesions 137 Osteochondroma may consist primarily of hemangiomatous type tissue, or of tortuous dilated lymphatic channels, most likely arising from a common cellular origin (Figures 6. Clinically, patients so affected may present with pain in the extremity, but more usually as a result of regional gigantism, leg length discrepancy, and limb deformity. Well defined, rounded calcifications (phleboliths) may be seen on radiographs. In more involved cases an entire limb or an entire portion of the body may be involved with these slowly enlarging lesions. The clinical manifestations usually require a combination of plastic surgery and orthopedic surgery. Osteochondroma (osteochondromatosis) The basic lesion of osteochondroma or osteochondromatosis is a benign cartilage capped protrusion of osseous tissue arising Figure 6.

It is best conceived as the body’s attempt to form an additional bone in an abnormal location. It is likely that these lesions arise as an aberration in the direction of growth within the peripheral portion of the epiphyseal growth plate, producing a bone that then proceeds to grow along the path of least resistance.

Pain at the ball of the foot may be a contusion or stress fracture of one of the sesamoid bones purchase 25 mg hydrochlorothiazide with visa. If the patient has plantar fasciitis buy hydrochlorothiazide 12.5 mg mastercard, the patient will give a history of insidious onset of medial plantar heel pain that begins on taking the first step of the morning order hydrochlorothiazide 12.5mg without prescription. Classically generic hydrochlorothiazide 25 mg without prescription, the pain alleviates after a few steps but tends to return later in the evening best 25 mg hydrochlorothiazide. Patients with sesamoiditis complain of pain that began or became more pronounced during jumping or pushing off to run. Patients with calcaneal or retrocalcaneal bursitis may complain of pain with running. Patients with stress fractures complain of pro- gressively worsening pain that usually is precipitated by an increase in activity intensity. For example, if the patient begins training for a marathon and is running more than usual, the patient may develop a stress fracture. Patients with an interdigital neuroma, metatar- salgia, hallux valgus, or hallux rigidus may complain of pain that began with a change in footwear. An insidious onset of intractable heel pain is indicative of tarsal tunnel syndrome. Patients with tarsal tunnel syndrome will complain of numbness and burning in addition to pain behind the medial malleolus and at the sole of the foot. Other important questions to ask include: What makes the pain better or worse? These questions are most helpful when deciding on imaging studies and treatment. Physical Exam Having completed taking your patient’s history, you are ready to perform your physical exam. Next, palpate the patient’s foot beginning with the first digit (hallux). Instruct the patient to dorsiflex as you dorsally palpate the first digit. Tenderness and decreased range of motion of the first metatarsalphalangeal (MTP) joint may indicate hallux rigidus. Pain elicited by resisted plantarflexion of the first digit may indicate flexor hallucis longus tenosynovitis. Tenderness to pal- pation over the fifth MTP indicates a Jones fracture, until proven oth-erwise with radiographs. Squeezing the metatarsal bones together while simultaneously pal- pating a painful web space is the compression test for interdigital neu- roma. If an interdigital neuroma is present, the involved web space should be tender to palpation with this maneuver. Allow the patient’s history to further guide your physical examina- tion. Palpate the bones of the foot, paying particular attention to any painful areas. Tarsal tunnel syndrome may cause pain, tingling, burning, and/or numbness in the sole of the foot. This exam and the management of this syndrome are discussed in Chapter 7. Passive dorsiflexion will stretch the plantar fascia and pain with this maneuver reveals plantar fasciitis (Photo 2). Medial heel tenderness at the plantar fascia attachments may also indicate plantar fasciitis. Part of the physical examination of a patient with foot pain includes examining the patient’s footwear. As you examine the footwear, ask yourself the following questions: are the shoes causing the foot pain? Plan Having completed your history and physical examination, you have a good idea of what is causing your patient’s foot pain. Treatment: Conservative care includes shoes with a wide toe-box and orthotics. Surgical excision of the deformity is reserved for severe cases that do not respond to conservative care. Foot Pain 125 Suspected retrocalcaneal bursitis Additional diagnostic evaluation: X-rays, including standing AP and lateral views, may be obtained.
