Occurrence and types of associated injuries in patients with fractures of the facial bones

PURPOSE: To identify the occurrence, types, and severity of associated injuries outside the facial region among patients diagnosed with facial fractures, and to analyze whether there are any factors related to associated injuries. MATERIALS AND METHODS: This was a cross-sectional study of 401 patients diagnosed with facial fractures during the 2-year period from 2003 to 2004. RESULTS: Associated injuries were observed in 101 patients (25.2%). The most common type of injury was a limb injury (13.5%), followed by brain (11.0%), chest (5.5%), spine (2.7%), and abdominal (0.8%) injuries. Multiple associated injuries were observed in 10% and polytrauma in 7.5%. The mortality rate was 0.2%. The occurrence of associated injury correlated significantly with trauma mechanism and fracture type; high-speed accidents and severe facial fractures were significant predictors of associated injury. CONCLUSIONS: Associated injuries are frequent among patients who have sustained facial fractures. The results underscore the importance of multiprofessional collaboration in diagnosis and sequencing of treatment, but also the importance of arranging appropriate clinical rotations for maxillofacial residents in training.

Prediction of hip and hand fractures in older persons with or without a diagnosis of periodontitis

Purpose: In a prospective study, we assessed if a diagnosis of osteoporosis and periodontitis could predict hip and hand fractures in older persons. Materials and methods: Bone density was assessed by a Densitometer. Periodontitis was defined by evidence of alveolar bone loss. Results: 788 Caucasians (52.4% women, overall mean age: 76 years, S.D. +/- 9.0, range: 62 to 96) were enrolled and 7.4% had a hip/hand fracture in 3 years. Calcaneus PIXI T-values < - 1.6 identified osteoporosis in 28.2% of the older persons predicting a hip/hand fracture with an odds ratio of 3.3:1 (95% CI: 1.9, 5.7, p < 0.001). Older persons with osteoporosis had more severe periodontitis (p < 0.01). Periodontitis defined by >= 30% of sites with >= 5 mm distance between the cemento-enamel junction (CEJ) and bone level (ABL) was found in 18.7% of the older persons predicting a hip/hand fracture with an odds ratio of 1.8:1 (95% CI: 1.0, 3.3, p < 0.05). Adjusted for age, the odds ratio of a hip/hand fracture in older persons with osteoporosis (PIXI T-value <-2.5) and periodontitis was 12.2:1 (95% CI: 3.5, 42.3, p < 0.001). Conclusions: Older persons with osteoporosis and periodontitis have an increased risk for hip/hand fractures

Permanent teeth with horizontal root fractures after dental trauma. A retrospective study

The purpose of the present retrospective study was to evaluate the post-traumatic healing of the pulp and periodontium of 32 permanent teeth with horizontal root fractures. Twenty-nine patients, 8-48 years old, who presented at our department with a root fracture between January 2001 and April 2007, participated in the study. Root-fractured teeth with a loosened or dislocated coronal fragment were repositioned and splinted for 14-49 days (average: 34 days). In cases of severe dislocation of the coronal fragment, prophylactic endodontic treatment was performed. Follow-up examinations were conducted routinely after 1,2,3,6, and 12 months. For this study, follow-up took place for up to 7 years post trauma. Of 32 root-fractured teeth, 29 (91%) survived. 10 teeth (31%) exhibited pulpal healing; 13 teeth (41%) were prophylactically endodontically treated within 2 weeks of injury. At the fracture line, interposition of calcified tissue was evident in 6 teeth (19%), and interposition of granulation tissue was observed in 8 teeth (25%). The prognosis of the root-fractured teeth was good, and one-third of the teeth with root fractures possessed a vital pulp at the final examination.

Greenstick fractures of the middle third of the forearm. A prospective multi-centre study

Greenstick fractures suffered during growth have a high risk for refracture and posttraumatic deformity, particularly at the forearm diaphysis. The use of a preemptive completion of the fracture by manipulation of the concave cortex is controversial and data supporting this approach are few.

Obesity, age, sex, diagnosis, and fixation mode differently affect early cup failure in total hip arthroplasty: a matched case-control study of 4420 patients

Studies about the influence of patient characteristics on mechanical failure of cups in total hip replacement have applied different methodologies and revealed inconclusive results. The fixation mode has rarely been investigated. Therefore, we conducted a detailed analysis of the influence of patient characteristics and fixation mode on cup failure risks.

Review of Lodox Statscan in the detection of peripheral skeletal fractures in multiple injury patients

As part of the primary survey, polytrauma patients in our emergency department are examined using the new 'Lodox Statscan' (LS) digital low-radiation imaging device. The LS provides full-body anterior and lateral views based on enhanced linear slot-scanning technology, in accordance with the recommended Advanced Trauma Life Support (ATLS) Guidelines. This study's objectives were to establish whether LS appropriately rules out peripheral bone injuries and to examine whether LS imaging provides adequate information for the preoperative planning of such lesions.

DensiProbe Spine: a novel instrument for intraoperative measurement of bone density in transpedicular screw fixation

STUDY DESIGN.: Cadaver study. OBJECTIVE.: To determine bone strength in vertebrae by measuring peak breakaway torque or indentation force using custom-made pedicle probes. SUMMARY OF BACKGROUND DATA.: Screw performance in dorsal spinal instrumentation is dependent on bone quality of the vertebral body. To date no intraoperative measuring device to validate bone strength is available. Destructive testing may predict bone strength in transpedicular instrumentations in osteoporotic vertebrae. Insertional torque measurements showed varying results. METHODS.: Ten human cadaveric vertebrae were evaluated for bone mineral density (BMD) measurements by quantitative computed tomography. Peak torque and indentation force of custom-made probes as a measure for mechanical bone strength were assessed via a transpedicular approach. The results were correlated to regional BMD and to biomechanical load testing after pedicle screw implementation. RESULTS.: Both methods generated a positive correlation to failure load of the respective vertebrae. The correlation of peak breakaway torque to failure load was r = 0.959 (P = 0.003), therewith distinctly higher than the correlation of indentation force to failure load, which was r = 0.690 (P = 0.040). In predicting regional BMD, measurement of peak torque also performed better than that of indentation force (r = 0.897 [P = 0.002] vs. r = 0.777 [P = 0.017]). CONCLUSION.: Transpedicular measurement of peak breakaway torque is technically feasible and predicts reliable local bone strength and implant failure for dorsal spinal instrumentations in this experimental setting.

Do Paediatric and Adult Surgeons Follow Different Approaches to Physeal Fractures?

INTRODUCTION: The treatment of paediatric fractures is the concern of several different surgical specialties. There has been no scientific investigation on the different concepts of paediatric (PS) and adult surgeons (AS). METHODS: 62 paediatric traumatologists were asked concerning their experience with physeal fractures of the leg, including ten cases. RESULTS: Growth disturbances was estimated to be more rare by PS. On evaluation of the examples there were no significant differences in the judgement of degree and direction of the displacement. For displaced fractures, PS rather preferred closed reduction and immobilisation, whereas AS favoured osteosynthesis. DISCUSSION: There were no basic differences between PS and AS in the treatment of lower limb fractures. AS tend to act more invasively. At the same time they are more concerned about growth disturbances.

[Intramedullary claw for stabilization of proximal humerus fractures: a comparison with other semirigid techniques]

Proximal humerus fractures (pHF) are common. In this retrospective study intra-operative and postoperative data and complications of patients stabilized with conventional semirigid techniques (pins, n=30; helix wire, n=19) or a novel semirigid technique, the intramedullary claw (IMC, n=82) were compared. The type and frequency of postoperative complications differed between the groups (p<0.001). The IMC is a novel semirigid technique to stabilize pHF and seems to result in fewer complications than pins or helix wire. The frequency and relevance of a loss of repositioning in patients after IMC implantation need to be elucidated in long-term studies.
