Spontaneous fractures in the differential diagnosis of fractures in children.

A four-year-old male with cerebral palsy and spasticity, as a result of a non-accidental head injury sustained when he was two years old, died of pneumonia. Postmortem full body X-rays revealed fractures of varying ages of the left humerus and both femora, tibiae, and fibulae. This led to a thorough investigation of the case by the Office of the Chief Medical Examiner. Child abuse, accidents, metabolic bone disorders, other primary or secondary diseases of the bones, and pathological fractures were ruled out. The final diagnosis was spontaneous fractures secondary to osteopenia. The term spontaneous fractures is used to define fractures that occur without any known external cause, especially in cerebral palsy patients with spasticity.

[Bilateral shoulder dislocation fractures, femoral neck and vertebral fractures: a remarkable combination of injuries during an epileptic seizure].

Fracture complications of convulsions are reported occasionally, e.g.: mono- or bilateral posterior shoulder luxations and luxation fractures, central dislocations of the hip as well as fractures of the femoral neck or compression fractures of vertebrae. A case is reported where the patient sustained four such lesions simultaneously. The epileptic seizure occurred following the sudden interruption of a neurotropic therapy with Carbamazepin (Tegretal). A general osteodystrophy was not found. The simultaneous presence of four such lesions following one convulsion has never before been reported and appears to be very uncommon. The frequency and problems of post-epileptic fractures are discussed and the operative treatment of the lesions briefly described.

[Treatment of a compound fracture of the mandible with a comminuted compound fracture of the maxilla (author's transl)].

A case is reported of a comminuted compound facial fracture associating a multisplintered comminuted compound fracture of the right palate, with a quadrifocal fracture of the mandible including severe displacement of fragments of a bi-subcondylar fracture. Treatment was difficult and consisted of producing a stable solid osteosynthesis of the body of the mandible allowing rapid extra-oral symphysial traction to reduce the condylar fractures for 3 weeks. Hospitalization lasted 33 days and the final buccal opening was 34 mm, with satisfactory dental articulation. The authors emphasize the need for a solid, stable osteosynthesis of the body of the mandible by using miniaturized plates serewed into the splintered facial complexes.

Does estimating volumetric bone density of the femoral neck improve the prediction of hip fracture? A prospective study. Study of Osteoporotic Fractures Research Group.

Standard projectional bone density of the femoral neck (BMD), defined as bone mineral content divided by the projected area of the neck, predicts hip fractures but may not accurately estimate the true volumetric bone density of the femoral neck. To determine whether an estimate of the volumetric bone density of the neck, "bone mineral apparent density" (BMAD), would be a better predictor of hip fracture, we analyzed dual x-ray absorptiometry scans obtained prospectively from 7963 older white women, of whom 83 suffered a hip fracture during follow-up. Both BMD and BMAD were stronger predictors than bone mineral content (BMC) of the femoral neck. However, BMD and BMAD had very similar predictive values for hip fracture: each standard deviation decrease in either BMD or BMAD of the femoral neck increased the age-adjusted risk of hip fracture 2.6- to 2.7-fold. We conclude that BMD and BMAD of the femoral neck have a similarly strong predictive value for hip fracture.(ABSTRACT TRUNCATED AT 250 WORDS)

Jogger's fracture and other stress fractures of the lumbo-sacral spine.

The posterior rings of the lower lumbo-sacral vertebrae are subject to stress fractures at any part - pedicle, pars, or lamina. The site of fracture is apparently determined by the axis of weight bearing. The three illustrative clinical examples cited include a jogger with a laminar fracture, a ballet dancer with pedicle fractures, and a nine-year-old boy with fractures of pars and lamina. Chronic low back pain is the typical complaint with stress fractures of the lower lumbo-sacral spine. Special imaging techniques are usually needed to demonstrate these lesions, including vertebral arch views, multi-directional tomography, and computed tomography (CT).

Occult fracture of the calcaneus--another toddler's fracture.

Fractures of the calcaneus have been considered rare among children. We feel this may be erroneous since in the last 12 months we have seen 10 such fractures among children, 19 and 41 months of age, who presented with acute limping. The fractures were detected with bone imaging which was performed when initial radiographs were noncontributory. Subsequent radiographs of the calcaneus were positive for fracture in 4 of 10 while follow up radiographs confirmed healing fractures in the two children so evaluated. The sensitivity of bone imaging for the detection of occult fractures in toddlers is emphasized.

The assessment of fracture of the mandibular condyle by use of computerized tomography. Incidence of sagittal split fracture.

A survey was carried out to clarify the incidence of sagittal splitting fracture of the mandibular condyle using computerized tomography. There were 33 patients, between 11 and 67 years of age, with displaced or dislocated mandibular condylar process fractures (41 cases), seen at our clinic between 1986 and 1992. The incidence of no displacement was 4.9%; deviation and displacement, 34.1%; dislocation, 46.3%; and complete avulsion, 4.9%. A sagittal splitting fracture of condyle occurred with an incidence of 9.8%. Conservative treatment was effective in the treatment of sagittal splitting fracture. Therefore, classification of fracture of mandibular condyle should include the sagittal split fracture, and investigations should include computerized tomography.

Design and baseline characteristics of the osteoporotic fractures in men (MrOS) study--a large observational study of the determinants of fracture in older men.

Very little information is available to direct the prevention or management of osteoporosis in men. The Osteoporotic Fractures in Men (MrOS) Study is a prospective cohort study designed to examine the extent to which fracture risk is related to bone mass, bone geometry, lifestyle, anthropometric and neuromuscular measures, and fall propensity, as well as to determine how fractures affect quality of life in men. The study is also designed to understand how osteoporosis is related to prostate disease. At baseline, participants completed questionnaires regarding medical history, medications, physical activity, diet, alcohol intake, and cigarette smoking. Objective measures of anthropometric, neuromuscular, vision, strength, and cognitive variables were obtained. Skeletal assessments included DEXA, calcaneal ultrasound, and vertebral radiographs. Vertebral and proximal femoral QCT was performed on a subset (65%). Serum, urine, and DNA specimens were collected. After the baseline assessments, a questionnaire is mailed to participants every 4 months to ascertain incident falls, fractures, prostate cancer, and deaths. After an average of 4.5 years, participants are scheduled to return for a second comprehensive visit. Men were eligible if > or =65 years. 5995 men enrolled with a mean (+/-SD) age of 73.7 (+/-5.9) years, 11% of which were minorities. Most rated their health as good/excellent. Few were current smokers, although 59% had smoked previously, and 35% reported no alcohol intake, while 47% consumed at least 2 drinks per week. The mean (range) body mass index was 26.9 kg/m2 (17-56). A non-traumatic fracture after age 50 was reported by 17% of the cohort. The MrOS cohort should provide valuable information concerning the determinants of fracture in men and should help set the stage for the development of effective methods to identify those at risk.

Catastrophic fracture of the lateral condyle of the third metacarpus/metatarsus in UK racehorses - fracture descriptions and pre-existing pathology.

The characteristics of, and pre-existing pathology associated with 75 cases of fatal lateral condylar fracture sustained by Thoroughbreds while racing in the UK were described. Cases were identified from 220 cases of fatal distal limb fracture submitted as part of studies designed to identify risk factors for all fatal distal limb fractures. Fractures were most common in hurdle races and affected the right forelimb twice as often as the left forelimb. Fracture dimensions were similar to previous reports, however there was a much greater prevalence of articular and diaphyseal comminution and of concurrent fractures in the current report. Pre-existing pathology was particularly common in the medial and lateral parasagittal grooves of the distal articular surfaces of the third metacarpus/metatarsus. The degree of this pathology was not associated with horse age, length of career or number of career starts.

Secondary hyperparathyroidism, vitamin D deficiency and hip fracture: importance of sampling times after fracture.

There is controversy about how often elevated parathyroid hormone (PTH) levels are found in hip fracture patients. The aim of this study was to determine whether changes in PTH levels after fracture and surgery could explain some of the variation in published data. Blood samples were obtained from 24 elderly patients with hip fracture before surgery, immediately after surgery and at 2 weeks and 3 months after fracture. PTH levels were elevated (> 5.5 pmol) in 33% initially and then fell significantly at 2 weeks in virtually all subjects (P < 0.001) and remained significantly lower after 3 months (n = 17). Although 25-hydroxyvitamin D levels were low (< 30 nmol) in 44% of the patients, the fall in PTH was not explained by alterations in vitamin D metabolites or other measured parameters. The cause of the variation in PTH levels is unknown but measurements immediately after fracture could overestimate the incidence of secondary hyperparathyroidism. Vitamin D deficiency is common in our hip fracture population and is not influenced by hospitalisation.

Malar bone fractures: experimental fractures on the dried skull and clinical sensory disturbances.

To improve understanding of malar bone fracture, experimental fractures on dried skulls and clinical sensory dysfunctions were investigated. In the experimental study, the fracture lines are largely confined to the suture lines between the zygoma and neighbouring bones in addition to the maxillo-ethmoidal suture. Antral walls, anterior and posterior, are relatively free from fracture lines in the region of the superior dental plexus. This coincides with the findings of dento-alveolar sensory disturbances which are relatively lower in incidence and earlier in recovery than those following Le Fort type fractures. To study this sensory status gives interesting information about the fracture lines and the anatomical course of the superior dental nerves.

[Fractures in the elderly--a challenge for prevention and health promotion--results from the KORA fracture study Augsburg].

Fractures of the appendicular bones are frequent and can cause a loss of the ability for independent living, depending on age and fracture localisation. They affect both sexes at different times and in different ways. The basic epidemiology for Germany of this injury resp. disease and knowledge regarding medium-term health-related consequences has been provided by work done in the context of the KORA Augsburg Fracture Study 1998, a follow-up of older participants of the third MONICA Augsburg survey S3 (1994/95) and through further research in the past years. Results of a validation study support the value of questionnaire-based patients recall of fractures and their location. It could be shown that age, gender, time since fracture and impaired walking have the greatest predictive value among a number of factors. Limitations of physical function are apparent especially during the first two years after a fragility fracture. After five years functional capacity of survivors equals the functional capacity of control persons of the same age. These population-representative and validated data support model-based cost-effective strategies of population-orientated disease prevention and health promotion. An age and gender-specific approach (gender mainstreaming) is mandatory.

Neck fracture femoral heads for impaction bone grafting: evolution of stiffness and compactness during impaction of osteoarthrotic and neck-fracture femoral heads.

BACKGROUND: The need for safe bone allografts is increasing and preservation of femoral heads from patients being operated on with hip arthroplasty should be encouraged. However, should we preserve femoral heads from patients operated on for neck fracture as tissue mechanical quality may not be satisfactory? MATERIAL AND METHODS: We compared the evolution of stiffness and compactness of fresh-frozen morselized bone obtained from osteoarthrotic femoral heads and those from neck fractures. Both materials were also compared after freeze-drying and irradiation. We used 6 osteoarthrotic and 6 neck-fracture femoral heads to prepare 4 batches of morselized bone. 18 samples from each batch were impacted in a contained cylinder. Frozen bone grafts were tested after thawing at room temperature for 2 hours and freeze-dried grafts were tested after 30 minutes of rehydration. RESULTS: The stiffness of fresh-frozen neck fracture bone was lower than that of fresh-frozen osteoarthrotic bone at 150 impactions. The stiffness of freeze-dried irradiated bone was higher than that of the fresh-frozen bone and did not differ between osteoarthrotic and neck-fracture bone. INTERPRETATION: Solvent-treated freeze-dried bone from femoral heads procured during arthroplasty for sub-capital hip fractures represents a valuable source of material for allografts, addressing concerns regarding serological testing, medical history and bone quality.

Surgical treatment for greater sphenoid wing fracture (orbital blow-in fracture).

The authors present 2 patients with greater sphenoid wing fractures that were treated surgically. This type of fracture is classified as a blow-in fracture of the lateral orbital wall. The first patient was a 16-year-old boy who was involved in a motor vehicle accident. Computed tomography (CT) disclosed a medial displacement of the inner wall of the greater sphenoid wing of the left orbit. He was unconscious for 3 days. After he recovered consciousness, he presented limited abduction of the left eye with diplopia in all gaze directions and mild left proptosis. Although these symptoms did not improve for 1 week, displaced bone fragments of the greater sphenoid wing were removed via the lateral orbital approach. The patient had a good postoperative course with progressive improvement in eye movement over the next several weeks. The second patient was a 22-year-old man whose face was hit in a fight. CT disclosed medial displacement of the inner wall of the greater sphenoid wing of the left orbit. Although the patient also presented limited abduction of the left eye on admission, this symptom improved gradually. However, diplopia in all gaze directions and mild left proptosis did not improve. Therefore, the displaced inner wall of the greater sphenoid wing was reduced via the lateral orbital approach. The patient showed a good postoperative course with progressive improvement over the next several weeks. This type of orbital fracture, which is classified as an orbital blow-in fracture, is relatively rare. This type of greater sphenoid wing fracture is caused by buckling of the orbital wall secondary to severe compression of the orbital rim. Surgical treatment using the lateral orbital approach through a hemicoronal skin incision afforded a wider operative field and better cosmetic result.

Body size and hip fracture risk. Swedish Hip Fracture Study Group.

The objective of this population-based case-control study was to determine the independent association between height, weight at different ages and adult weight change on hip fracture risk, and the joint effects of these factors. The study base comprised postmenopausal women 50-81 years of age who resided in six counties in Sweden during the period October 1993 to February 1995. The study included 1,327 cases with an incident hip fracture and 3,262 randomly selected controls. We obtained information on body measures and other factors possibly related to hip fracture through mailed questionnaires and telephone interviews. Height and weight change were dominant risk factors. Tall women (> or = 169 cm) had an odds ratio of 3.16 (95% confidence interval = 2.47-4.05) compared with women shorter than 159 cm. Weight gain during adult life was strongly protective: compared with those with moderate weight change (-3 to 3 kg), those with substantial weight gain (> or =12 kg) had a markedly decreased risk of hip fracture (odds ratio = 0.35; 95% confidence interval = 0.27-0.45), whereas weight loss was associated with an increased risk. Weight change retained important effects among all subjects, even after controlling for current weight and weight at age 18. In contrast, among women who gained weight, the separate effects of current weight and weight at age 18 were small or absent. Among women who lost weight, both current weight and weight at age 18 had effects that remained after controlling for weight change. Adult weight change and height are dominant body size risk factors for hip fracture. Weight loss vs weight changes demarcates different patterns of hip fracture risk.

Impact of CT scan on treatment plan and fracture classification of tibial plateau fractures.

OBJECTIVE: To evaluate the interobserver and intraobserver agreement for both treatment plan and fracture classification of tibial plateau fractures using plain films alone and with computed tomography (CT) scans. DESIGN: Prospective study to assess the impact of an advanced radiologic study on the agreement of treatment plan and fracture classification of tibial plateau fractures. SETTING/PARTICIPANTS: Two orthopaedic traumatologists, two orthopaedic residents, and two skeletal radiologists were presented with twenty-one cases of tibial plateau fractures imaged with plain films and with CT scans. MAIN OUTCOME MEASURES: Agreement was measured using kappa coefficients. RESULTS: Using plain films alone, the mean interobserver kappa coefficient for classification was 0.62, which decreased to 0.61 after addition of CT scans. Using plain films alone for formulating a treatment plan, the mean interobserver kappa coefficient was 0.58, which increased to 0.71 after addition of CT scans. The mean intraobserver kappa coefficient for fracture classification using plain films was 0.70, which increased to 0.80 with addition of CT scans. The mean intraobserver kappa coefficient for treatment plan based on plain films alone was 0.62, which increased to 0.82 after addition of CT scans. Class was changed in an average of 12 percent of cases after addition of CT scans. Treatment plan was changed an average of 26 percent of the time after addition of CT scans. CONCLUSION: Addition of CT scans to plain roentgenograms increases the interobserver and intraobserver agreement on treatment plan.

Maisonneuve fracture associated with a bimalleolar ankle fracture-dislocation: a case report.

The Maisonneuve fracture consists of a proximal fibular fracture with associated syndesmotic ligament disruption and injury to the medial ankle structures. The accepted mechanism of injury is an external rotation force applied to the ankle with the foot in either supination or pronation. Because most Maisonneuve fractures involve complete syndesmotic disruption, operative treatment is usually indicated. A case report is presented of an unusual fracture pattern-i.e., that of a distal fibular fracture with lateral ankle dislocation associated with a Maisonneuve fracture. To our knowledge, only two other similar cases are reported in the English literature.

Treatment of scapula fractures: systematic review of 520 fractures in 22 case series.

BACKGROUND: Fractures of the scapula account for 3% to 5% of all fractures of the shoulder girdle and make up less than 1% of all broken bones. Scapula fractures typically occur after high-energy trauma, and approximately 90% of the patients have associated injuries. OBJECTIVE: (1) To determine the incidences of nonoperative and operative treatment of different scapula fracture types, (2) to systematically stratify the reported results of nonoperatively and operatively treated scapula fractures on the basis of different fracture types and to summarize functional results, and (3) to quantify infection and secondary surgical procedure rates after operative treatment.
