Background: Gunshot wounds impose a continuous burden on community and hospital resources. Gunshot injuries to the extremities might involve complex soft tissue, bone, vascular, musculotendinous, and nerve injuries. A precise knowledge of anatomy is needed to evaluate and treat those injuries.

Objectives: To review our experience with gunshot wounds to the extremities.

Methods: We retrospectively reviewed all cases of gunshot wounds to the limbs in a civilian setting treated in our institution during 2003–2005. Altogether, we evaluated 60 patients with 77 injuries.

Results: Of the 60 patients 36 had fractures, 75% of them in the lower extremity and 81% in long bones. The most common fixation modality used was external fixation (33%), followed by intramedullary nailing (25%). This relatively high percentage of fracture treated with external fixation may be attributed to the comminuted pattern of the fractures, the general status of the patient, or the local soft tissue problems encountered in gunshot wounds. About one-fifth of the fractures were treated by debridement only without hardware fixation. We treated 10 vascular injuries in 8 patients; 6 of them were injuries to the popliteal vessels. Fractures around the knee comprised the highest risk factor for vascular injuries, since 5 of the 12 fractures around the knee were associated with vascular injury requiring repair or reconstruction. There were 13 nerve injuries (16.8%), most of them of the deep peroneal nerve (38%). Only three patients had concomitant nerve and vascular injuries. The overall direct complication rate in our series was 20%.

Conclusions: Treating complex gunshot injuries requires a team approach, necessary for a favorable outcome. This team should be led by an orthopedic surgeon knowledgeable in the functional anatomy of the limbs.
 

In recent years the survival of patients with systemic lupus erythematosus has increased markedly. Consequently, long-term complications, such as osteoporosis, are currently of paramount importance. SLE[1] is known to increase the risk of bone fractures, and numerous studies have found that SLE patients have osteoporosis. Of the various risk factors associated with osteoporosis in SLE, disease duration, the use of corticosteroids and chronic disease-related damage are consistently reported, with differences between studies probably due to the different populations studied. The role of chronic inflammation in osteoporosis is also important. On the other hand, little attention has been paid to osteoporotic fractures, especially of the vertebra, which are associated with reduced quality of life, increased mortality rates and increased risk of new vertebral and non-vertebral fractures in the general population.

Background: Fracture of the scaphoid is the most common fracture of a carpal bone. Nevertheless, the diagnosis of SF[1] might be challenging. Plain X-rays that fail to demonstrate a fracture line while clinical findings suggest the existence of such a fracture is not uncommon. Currently there is no consensus in the literature as to how a clinically suspected SF should be diagnosed, immobilized and treated.

Objectives: To assess the current status of diagnosis and treatment of clinically suspected scaphoid fractures in Israeli emergency departments

Methods: We conducted a telephonic survey among orthopedic surgeons working in Israeli EDs[2] as to their approach to the diagnosis and treatment of occult SF.

Results: A total of 42 orthopedic surgeons in 6 hospital EDs participated in the survey. They reported performing a mean of 2.45 ± 0.85 clinical tests, with tenderness over the snuffbox area being the sign most commonly used.  A mean of 4.38 ± 0.76 X-ray views were ordered for patients with a clinically suspected SF. The most common combination included posterior-anterior, lateral, semipronated and semisupinated oblique views. All participating surgeons reported immobilizing the wrists of patients with occult fractures in a thumb spica cast based on their clinical findings. Upon discharge from the ED patients were advised to have another diagnostic examination as follows: 29 (69%) repeated X-rays series, 18 (43%) were referred to bone scintigraphy and 2 (5%) to computed tomography; none were referred to magnetic resonance imaging.

Conclusions: No consensus was found among Israeli orthopedic surgeons working in EDs regarding the right algorithm for assessment of clinically suspected SF. There is a need for better guidelines to uniformly dictate the order and set of tests to be used in the assessment of occult fractures.

Background: Fractures of the femur in neonates are relatively uncommon. The infants feel pain and discomfort, causing parental distress, and the hospital stay is longer. Treatment of this specific fracture is problematic because of the small size of the baby.

Objectives: To review the results of the treatment of neonatal femoral fractures.

Methods: We retrospectively reviewed all neonatal fractures of the femur during a 12 year period. Thirteen fractures of the femur in 11 babies were treated with improvised Bryant skin traction of both legs. All the patients were re-examined after a mean follow-up period of 5.2 years.

Results: All fractures healed satisfactorily clinically and radiographically, with no residual deformity, no leg length discrepancy and no functional impairment.

Conclusions: Bryant’s traction for 2–3 weeks in hospital is a safe method for the treatment of femoral fractures in neonates, and the outcome is good.
 

Objectives: To evaluate trends in the incidence of hip fractures in this population.

Methods: The study was based on two surveys done approximately 20 years apart. It included women and men 50 years and older with radiographic evidence of a new hip fracture caused by low impact trauma. Only fractures that resulted from low or moderate trauma were considered for the current study. Incidence rates were calculated based on population data obtained from the official Central Bureau of Statistics.

Results: There was an overall twofold increase in the incidence rate of hip fractures. However, this increase occurred almost exclusively in the over-75 year old age groups (2.5-fold increase, both in women and men). The mean (and median) age of patients with hip fractures increased significantly over the study period, corresponding with the increase in longevity between the two periods.

Conclusions: There was a marked secular increase in the incidence of proximal hip fractures in both genders, primarily because of an increase in the fracture rate in the very old. The increase in median age of fracture patients suggests that the observed increase in fracture rate can be attributed mainly to aging of the population rather than to deterioration in bone quality over the generations.

Objectives: To use pelvic fractures as a test case for the efficiency of the Israeli trauma system, as reflected in the experience of our medical center.

Methods: Data were obtained from the medical charts of all cases of pelvic fractures admitted to our medical center between 1987 and 1999. We obtained demographic data, information on the cause of injury, fracture classification, co-injuries and Injury Severity Score, treatment strategies, and mortality rate.

Results: Altogether, 808 patients with pelvic injuries were treated in our medical center. The most common cause of injury was motor vehicle accidents (51%). Pelvic fractures without acetabular involvement were diagnosed in 58% of patients and isolated acetabular fractures in 32%, while 10% sustained combined injuries to the pelvic ring and the acetabulum. The overall rate of operative stabilization was 34%. The majority of patients had associated injuries, mostly additional musculoskeletal injuries. Altogether, 13% were referred from Level II/III trauma centers. We observed an increase in the total number of local admissions, in the percentage of referred patients and in the percentage of operated patients during the study period. The observed mortality rate was 5%.

Conclusions: Our results show a more than twofold increase in the percentage of referred patients following the designation of a Level I trauma center. These referrals result not only from the designation as a Level I trauma center, but also from the presence of a dedicated team of pelvic fracture specialists, available 24 hours a day. In addition, a larger percentage of patients undergo surgery for internal fixation of pelvic fractures, in accordance with current worldwide trends.

Objectives: To report our experience in the treatment of pelvic fractures.

Methods: Between October 1998 and September 2001, 78 patients with pelvic fractures were admitted to our hospital. The age range of the 56 male and 22 female patients was 16–92 (mean 42 years). The cause of injury was road accident in 52 patients, fall from a height in 15, a simple fall in 9, and gunshot wounds in 2 patients. The Glascow Coma Scale score on arrival at the hospital was 3–15 (average 12). Twenty-five patients (32%) were admitted to the intensive care unit, 38 (48%) to the orthopedic department, 5 (6.4%) to neurosurgery and the remainder to a surgical department.

Results: Twenty-six patients (33.3%) received blood transfusion in the first 24 hours. Of the 25 patients (32%) with associated head trauma, 6 had intracranial bleeding; 29 patients (37%) had associated chest trauma, 28 (35.9%) had associated abdominal trauma, 16 (20.5%) had vertebral fractures and 40 (51.2%) had associated limb fractures. Pelvic angiography was performed in 5 patients (6.4%), and computed tomography-angiography of the cervical arteries and chest was performed in 1 and 5 patients respectively. Overall, a CT scan was performed in 56 patients (71.8%), of whom 25 (32%) had a pelvic CT on admission. Injury Severity Score was 4–66 (median 20). Laparotomy was performed in 14 patients (18%), spinal fusion in 5 (6.4%), limb surgery in 16 (20.5%), cranial surgery in 4 (5.02%), pelvic surgery in 10 (12.8%), chest surgery in 3 (3.85%), and facial surgery in 2 patients (2.56%). Seven patients (9%) died during the course of treatment.

Conclusion: Pelvic fracture carries a high morbidity rate. Associated chest, abdomen and limb injuries are often encountered. A multidisciplinary approach is needed to improve survival and outcome in patients with pelvic fractures. 

Background: Femoral hip fractures are a common occurrence in the elderly. Of the various fracture patterns, intertrochanteric injuries have the lowest rate of complications. Case reports of ensuing subcapital fracture have all been linked to incorrect placement of fixation devices or to osteomyelitis, while cases of avascular necrosis have only been reported rarely in the literature and are considered to occur at the rare rate of 0.8%.

Objectives: To check the incidence and outcome of AVN[1] in intertrochanteric hip fractures.

Methods and Results: In a retrospective analysis of patients who had surgical treatment for intertrochanteric fractures, 10 patients (0.5%) underwent dynamic hip screw fixation for intertrochanteric fractures and subsequently developed painful AVN as their primary presentation. Three of these patients were also found to have subcapital fractures. On revision of the primary fixation no fault was found with nail placement.

Conclusions: The reported rate of AVN may be understated since many patients have limiting factors that prevent them from consulting a physician when in pain, and one-third of these patients die within 2 years. Therefore, we suggest that hip pain following fixation of an intertrochanteric fracture should prompt the clinician to consider the rare possibility of AVN or subcapital fracture.

Background: Open reduction and internal fixation are the current trends of treatment for comminuted calcaneal fractures. Assessing treatment results is often difficult due to discrepancy between objective parameters such as range of movement, and subjective results such as pain.

Objectives: To test the reliability of footprint analysis as an adjuvant method of postoperative assessment of patients who sustained calcaneal fractures.

Methods: Dynamic and static footprint analysis was used as an adjuvant method to objectively assess operative results. This method is simple and is independent of the patient’s initiatives. This modality was used in 22 patients followed-up 9–90 months postoperatively.

Results: We found a good correlation between footprint analysis and objective and subjective parameters of results expressed by the American Orthopedic Foot and Ankle Society hind foot score. In certain cases, this method can be used to distinguish between uncorrelated parameter results, such as malingering, and workmens’ compensation claims.

Conclusion: We recommend the use of this simple, non-invasive objective test as an additional method to assess the results of ankle and foot surgery treatment.
 

Background: The progressive increase in the number of elderly patients with hip fractures and the particular multidisciplinary needs of this population call for the investigation of other models of orthogeriatric care.

Objectives: To describe the nature and assess the feasibility of a comprehensive orthogeriatric unit attending to patients' surgical, medical and rehabilitation needs in a single setting.

Methods: This retrospective chart review describes consecutive older patients with hip fractures admitted directly from the emergency ward to an orthogeriatric ward.

Results: The mean age of the 116 patients evaluated was 82.4 years. Delay to surgery was 3.6±3.1 days and total length of stay 23.9±11.0 days. No patient was transferred to other acute medical wards of the hospital and 66.4% were able to return to their previous living place. Rates of major complications and mortality were extremely low.

Conclusion: The present model of a comprehensive orthogeriatric ward is a practical, applicable and feasible service for elderly hip fracture patients and can cover the various needs of these patients. The deployment arrangements needed to establish and operate the ward were minimal and there were only a few management and organizational problems. The cost-effectiveness and other comparative benefits of this type of service have yet to be clarified.
