Complications in leg lengthening using an Ilizarov external fixator and intramedullary alignment in children: comparative study during a fourteen-year period

BACKGROUND The purpose of this retrospective study was to evaluate the complications associated with leg lengthening in children treated with the Ilizarov external fixator (IEF) and compare them between two groups of patients: one group was treated using an IEF alone and the other group was treated using an IEF in association with intramedullary alignment (IA). PATIENTS AND METHODS The study was performed at the University Childrens Hospital in Belgrade, Serbia during a fourteen-year period (from 2000 to 2014). Complications occurred in 73 paediatric patients who underwent the leg lengthening procedure. Complications were classified according to the Caton classification and compared between two groups. Group I comprised 39 patients who underwent the limb lengthening procedure using IEF alone. Group II consisted of 34 patients who were treated with the combination of IEF and IA using two Kirschner wires (K-wires) or Titanium Elastic Nails (TEN). The duration of hospital treatment was also compared between the two groups and the impact of the type of IA on the occurrence of complications was assessed. RESULTS There was a high rate of complications in patients treated using an IEF compared with those treated using the combination of IEF and IA, but there was no statistically significant difference between the two groups. There was a statistically significant difference in the duration of initial hospitalisation between the two groups, particularly when comparing TEN usage in IA. A comparison of the group of patients treated using an IEF in association with K-wires and patients treated using IEF and TEN showed there was no statistically significant difference in complication rate and duration of initial hospitalisation. CONCLUSION IA has multiple advantages as a method of treatment of leg length inequality. The major effect of applying IA in association with a circular IEF is significantly reduced complication rate and duration of initial hospitalisation, particularly when using TEN as a method of IA. This method of treatment also decreases hospital costs.

Complications of ESIN osteosynthesis—Experience in 270 patients

BACKGROUND Elastic stable intramedullary nailing (ESIN) osteosynthesis has been used in our department for the treatment of long-bone fractures in children and adolescents for more than 17 years. During this period we have shown that ESIN has several advantages compared with other methods of treatment. However, as with every other method, ESIN has its drawbacks and complications. These occur primarily if indication criteria are not respected or ESIN technique is inadequate. This paper presents the rate of complications that occurred with this method in our patients, and the means of prevention and treatment of these complications. PATIENTS AND METHODS A total of 270 patients treated with ESIN osteosynthesis for fractures of long bones of the extremities completed treatment. The study was conducted at the Department of Child Surgery and Orthopaedics of the Clinical Hospital Centre in Rijeka. All the Nancy Nails used in the study were of the same quality, from one manufacturer and were applied using the standard ESIN technique. In 228 patients (84%), ESIN was the primary treatment, whereas in the remaining 42 patients (16%), ESIN was applied after an attempt at manual reposition and immobilisation of bone fragments. All patients had control radiography at least three times and postoperative monitoring was conducted for at least two years. RESULTS A total of 35 of the 270 observed patients developed complications; some patients had several complications. There were 53 early intraoperational complications and 29 late postoperative complications. All complications resolved with appropriate therapy. The treatment was satisfactory in all patients except those with an elongation of the extremity (leg) of more than 1cm. CONCLUSION Postoperative complications related to the ESIN method of osteosynthesis in the patients in this study were detected by radiological control examinations and long-term clinical monitoring. All the complications of ESIN were relatively easy to treat with current medical methods. The frequency of particular complications is significantly reduced if indication criteria for ESIN are respected and correct ESIN technique is used.

High pressure injection injury of the foot: a role of negative pressure wound therapy.

High pressure injection injuries (HPII) of the foot are not common in every-day practice. We present a 50-year-old patient with a HPII of the left foot caused by water-gun in a self-inflicted accident working as a technical diver four meters under the sea surface. Surgical treatment included extensive debridement of necrotic tissue and fibrin deposits and removal of foreign material. A negative pressure wound therapy (NPWT) device was applied resulting in a good wound base for subsequent skin grafting leading to a good functional and cosmetic outcome.

Femoral neck fractures in children and the role of early hip decompression in final outcome

BACKGROUND Femoral neck fractures in children are very rare and account for about 1% of all paediatric fractures. The aim of this retrospective study was to analyse the clinical and radiographic outcome in paediatric femoral neck fracture and to review the role of early decompression of the hip in the final outcome. PATIENTS AND METHODS The study was performed at the Department of Paediatric Orthopaedics and Traumatology, University Childrens Hospital in Belgrade, Serbia from January 1996 to January 2010. The study included 28 patients, 12 female and 16 male, aged 4-14 years. Patients who were aged over 14 years or who had pathological femoral neck fractures or metabolic disturbances were excluded from the study. The type of neck fracture was determined according to the Delbet and Colonna classification. The patients were treated using different surgical procedures: closed reduction and cast immobilisation, closed reduction and percutaneous fixation with Kirschner wires (K-wires), closed reduction and fixation with cannulated screws and open reduction with Wagner plate stabilisation. The final outcome was evaluated using the clinical outcome (based on the Howorth-Ferguson scale), radiographic outcome and occurrence of complications. RESULTS The median age of patients included in the study was 10.75 years and the average follow up was 9 years. According to the Delbet classification, there was one patient with type I, eight patients with type II, 16 patients with type III and three patients with type IV femoral neck fracture. Based on the Colonna classification, there were 23 displaced and five non-displaced femoral neck fractures. Decompression of the hip was performed in 21 patients. Avascular necrosis (AVN) developed as the main complication in 11 patients. The final outcome was excellent in 14 patients, good in four patients and poor in 14 patients. CONCLUSION Our study unequivocally confirms the positive effect of urgent treatment on the incidence of AVN as well as on the outcome. We have established a 12-hour interval after injury as an optimal time limit for commencing treatment. Unambiguously positive effects of hip decompression on the incidence of AVN were also noted. We found similar efficiency for open and needle hip decompression.

Pattern of emergency room mortality among road traffic crash victims

Road traffic injuries are a major cause of death in the emergency room. The goal of this study was to highlight the demographic pattern of road traffic-related deaths in the accident and emergency room of a regional trauma centre. This was a 5-year retrospective study in which road traffic-related cases of emergency room mortality between June 2009 and June 2014 were reviewed. A total of 33 road traffic crash-related deaths occurred during this period with a male-to-female ratio of 2.3:1. Most of these patients were pedestrians with severe injuries involving two or more Abbreviated Injury Scale (AIS) coded regions. The mean time between injury and presentation in the first trauma facility was 112.1 (±55.4)min, and between presentation in the emergency room and death was 410 (±645)min. Mangled lower extremity, bilateral long bone lower limb fractures, pelvic injuries, blunt injuries to the chest and abdomen, and cranial fossae fractures were the common injury pattern. Median ISS and NISS in these patients were 22 (interquartile range [IQR]=11) and 25 (IQR=17), respectively. Severe injuries, delayed presentation, multiple referrals and delayed resuscitative measures contribute to road traffic crash-related mortality.

A retrospective study of antibiotic prophylaxis value in surgical treatment of lower limb fracture

BACKGROUND Surgical site infections (SSI) are nosocomial infections that cause considerable problems in orthopaedic surgery. Antibiotic prophylaxis can be used to reduce the risk for SSI. There is no universal antibiotic that can be recommended for prophylaxis in terms of coverage of all possible pathogens because of antibiotic resistance, and there are no universal recommendations for different types of patients in terms of injury type, selected operation and risk factors for development of SSI. The aim of this study was to analyse the effectiveness of antibiotic prophylaxis in surgical treatment (ORIF) of closed lower limb fractures in young, healthy patients. PATIENTS AND METHODS Patient details were collected from the patient histories. Inclusion criteria for participants were age 20-30 years, not suffering from any type of chronic disease or state that may affect postoperative infection and ISS≤9. Antibiotic prophylaxis use and outcome (SSI) were compared between two groups of patients. Data were analysed using descriptive statistics, Fishers exact test and t-test for proportions. RESULTS A total of 347 patients with closed lower limb fractures treated with ORIF met the inclusion criteria. There were 290 male and 57 female patients, with an average age of 24.47 years. Prophylactic antibiotics were given to 242 patients (69.74%); 2g ceftriaxone was administered to 88.02% of the patients who received antibiotic prophylaxis. Ten patients developed postoperative infection (eight out of 242 with antibiotic prophylaxis and two out of 105 without antibiotic prophylaxis). The difference between the two groups was not statistically significant (Fishers exact test, P=0.749). CONCLUSION Antibiotic prophylaxis was ineffective in preventing SSI in patients with no risk factors for SSI who were undergoing ORIF for closed lower limb fractures.

Chronic unreduced shoulder dislocations: Experience in a developing country trauma centre

Chronic shoulder dislocations are extremely rare. The goal of this retrospective study was to describe the epidemiology of chronic shoulder dislocation in our environment and to evaluate the outcome of treatment. Bio-demographic data and injury details were retrieved from case files. Definitive method of reduction and stabilisation and duration of follow-up care were also noted. Nine cases of subcoracoid anterior chronic shoulder dislocation were seen during the 6-year period of the study. Seven (78%) of these patients were male and two (22%) were female. The mean age was 42 (±17.5) years. The common mechanisms of injury were road traffic crash in four patients (44%), domestic falls in four patients (44%) and dislocation while getting out of bed in one patient (12%). None of the patients had neurovascular deficit at presentation. Five patients were managed operatively and four were managed non-operatively. Mean follow-up was 8 months (range 6-12 months). Clinical evaluation by Rowe shoulder score revealed that operated cases had significantly higher mean rank scores than non-operated cases using the Mann-Whitney U test. Two operated cases were graded fair and three poor. All cases managed non-operatively had poor outcome grades. Meticulous attempt at soft tissue repair and early supervised physiotherapy can contribute to a favourable outcome.
