Dual mobility total hip replacement: a 15-year experience in Burkina Faso.

To report our 15 years of experience in dual mobility total hip replacement (THR) in Burkina Faso through a Franco-Burkinabé relief organization. A retrospective study spanning from 2004 to 2018 was held in a private facility. All dual mobility THR cases with at least one year of follow-up time were included. The survey used a questionnaire, and data were analyzed with statistical software (Stata® v.13). A total of 145 primary THR in 129 patients were included in disabled young patients. There was 60.46% of males (n=78) with a mean age of 44.57 years (SD=12.43). The mean etiologies were avascular necrosis of the hip (n=84), followed by childhood chronic arthritis sequalae (n=24, 16.55%) and trauma sequalae (n=13, 8.97%). All prostheses were metal-on-polyethylene from Zimmer-Biomet®. It was usually small sizes with 48 mm (females) and 50 mm (males) cups, stem 1 (female) and 3 (males). After 2.70 years (SD=2.66) of mean follow-up times, results were good despite a high rate of revision (n=10, 6.89%) due to infections and implant malposition. THR practice might be encouraged in developing countries. The dual mobility concept is adapted to sociological activities. High duration implants and cost limitation is mandatory for the replacement joints diffusion.

Use of dual mobility cups for total hip arthroplasty in sub-Saharan Africa: interest and perspectives.

INTRODUCTION: Hip arthroplasty and revision surgery are growing exponentially in OECD countries. In developing countries, it is an infrequent intervention and its practice is limited. It is exposed to a higher rate of infectious and mechanical failures than in developed countries. The aim of the actual study is to provide a review of the literature on total hip arthroplasty series in sub-Saharan Africa followed by an overview of the interest and perspectives of the use of dual mobility (DM) cups. MATERIALS AND METHODS: Scopus, EMBASE, Medline, PubMed, and Safoonline databases were searched including papers published at any date. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. All papers from South Africa were excluded. RESULTS: We identified 22 series of total hip arthroplasty in 14 SSA countries. The practice of total hip arthroplasty is not very widespread. The cups used are mostly conventional implants, and complications (mechanical and infectious) are frequent. DISCUSSION: The interest for the use of dual mobility cups in sub-Saharan Africa can be summarized in two points: mechanical and socio-economical. Dual mobility cups provide more mechanical stability and a reduction in the overall cost of treatment by reducing the rate of complications. These prospects will make it possible to evaluate this medical device in the long term in a hostile environment conductive to complications. CONCLUSION: The use of dual mobility deserves to be developed in African settings.

Focus on interlocking intramedullary nailing without fluoroscopy in resource-limited settings: strategies, outcomes, and outlook.

INTRODUCTION: Closed static interlocking nailing with c-arm guidance is the standard procedure for the treatment of closed diaphyseal fractures. In low-income settings, it is still very difficult to carry out such procedures because of few or absent image intensifiers (c-arm) despite the necessity. Authors provide a review of the literature on interlocking intramedullary nailing without fluoroscopy in resource-limited settings, followed by strategies, outcomes, and outlook. MATERIALS AND METHOD: A comprehensive search of the PubMed, Web of Science, Embase, and Cochrane Library databases was performed with the help of a biomedical information specialist. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. RESULTS: We identified 15 series of interlocking intramedullary nailing without fluoroscopy in resource-limited settings. All papers focused on the care for long bones (humerus, femur, tibia). All studies discussed the quality of the nailing operative procedure. The entry point was described in five series; the nail insertion in the proximal and distal medullary canal was good in all studies. The distal locking was missed between 0 and 27%. DISCUSSION: Intraoperative strategies depend on the type of bone affected, the opening of the fracture site, the fracture line, and the availability of a functional orthopaedic table. Three techniques to insert the nail in the proximal and distal fracture fragment with reduction of the fracture site are described. Insertion of distal screws is possible by using ancillary devices. Outcomes are comparable to those of the series using c-arm guidance. In low-income countries, it can been proposed as an alternative to the gold standard in resources constraints settings. In high-income setting this technique can help to reduce exposure of X-ray. CONCLUSION: There is a need to improve equipment in low-income countries hospitals to make trauma surgery with c-arm a gold standard with a minimal exposure to radiation.

Reduction of Neglected Displaced Fractures of the Distal Femoral Physis.

BACKGROUND: We performed open osteoclasis, soft-tissue release, and fracture fragment reduction and fixation to treat 10 cases of neglected physeal fractures of the distal aspect of the femur with severe deformity. To our knowledge, no specific surgical procedure for this problem has been reported in the literature. DESCRIPTION: The procedure is typically performed through an extensile anterolateral approach. With use of an osteotome, the typically abundant fracture callus is disrupted and partially removed to recreate the original fracture line. Through periosteal dissection, an extensive musculoperiosteal detachment and release is achieved to facilitate fracture reduction while protecting the physis from further injury. ALTERNATIVES: Knee rehabilitation in closed, nondisplaced or minimally displaced fractures1.Open callus osteoclasis in combination with a Z-shaped quadriceps tenoplasty, reduction, and plaster cast immobilization2.Open subperiosteal osteoclasis, reduction, and tibial traction3.Open callus osteoclasis, reduction, and condylar plating4.Sequestrectomy with preservation of a periosteal sleeve to treat osteomyelitis complicating an open fracture1.Transfemoral amputation to treat gas gangrene or vascular injury following severe open injury1,5-7. RATIONALE: This procedure was developed in remote medical facilities where patients are often first seen >21 days after the original injury. By that time, closed reduction or standard open reduction and internal fixation techniques are no longer possible. After 6 months of fracture age, the procedure is inefficient. EXPECTED OUTCOMES: This procedure allows correction of limb malalignment and shortening while preserving the growth plate1. IMPORTANT TIPS: In some cases, hypertrophic fracture callus might be mistaken for the femoral diaphysis.An extensive musculoperiosteal release will facilitate reduction of the fracture fragments.The adequacy of reduction must be assessed in all 3 planes intraoperatively.The adequacy of reduction must be assessed in all 3 planes intraoperatively.The adequacy of reduction must be assessed in all 3 planes intraoperatively.

Bilateral anterior shoulder dislocations: A review of two cases and the relevant literature.

The bilateral symmetric anterior shoulder dislocations (BSASD) must be suspected in patients with bilaterally flattened shoulders after an uncontrolled muscular contraction like seizure condition. BSASD is best managed acutely and challenging to manage when diagnosed late. Chronic BSASD, after two years in a young patient, can result in fair functions.

Management of neglected distal femur epiphyseal fracture-separation.

INTRODUCTION: Neglected epiphyseal fracture-separations of the distal femur are rare. Still reported in developing countries, they lead to therapeutic issues. The objective of the study is to describe their characteristics and to propose treatment options. MATERIALS AND METHODS: Ten years of ongoing study was held in our orthopedics department. All patients with a neglected epiphyseal fracture-separations of the distal femur after a knee trauma were included in the study. Pre-operative and post-operative data were collected and analyzed. RESULTS: A total of 13 cases of neglected traumatic epiphyseal fracture-separations of the distal femur were found among 8616 in-patients of the department. It was mainly boys (9M/4F) around 16 years that were received 14 weeks after knee trauma. Most of the injuries were an AO-type 33-E/2.1 (Simple Salter-Harris' type II) (n=12) distal femur malunion (n=10). Associated complications were cutaneous opening (n=7), superficial infection (n=4), deep infection (n=4). Fractures were management surgically (n=12) by an open osteoclasis procedure (n=9), debridement (n=7) and a thigh amputation (n=1). The outcome was better if an open osteoclasis procedure was early performed in closed distal femur mal-union with a complementary rehabilitation program. CONCLUSION: Specialized trauma care facilities must be increased, and trauma education programs must be undertaken to avoid neglected epiphyseal fracture-separations of the distal femur in developing countries.

[Severe acute limb ischemia resulting in rescue disarticulation in a patient with Nicolau syndrome following intramuscular penicillin injection: a case report]. / Ischémie aiguë de membre sévère sanctionnée par désarticulation de sauvetage dans un contexte de syndrome de Nicolau suite à une injection intramusculaire de pénicilline: à propos d'un cas.

We here report the case of a 9-year-old child suffering from Nicolau syndrome involving the left pelvic limb with severe acute limb ischemia following intramuscular benzathine penicillin injection into the buttock. Given the rarity of acute limb ischemia in children, this case of complicated Nicolau syndrome combining acute arterial thrombosis and severe rhabdomyolysis leading to rescue hip dislocation is very interesting.

Trauma related to falls from trees treated in a specialized trauma centre in Burkina-Faso-one hundred and six cases treated in one year.

PURPOSE: Falls from trees related traumas are rarely reported in literature. They are public health problems in developing countries where their frequency is still important. The aim of the study is to describe falls from trees related trauma patterns and to present preventative measures. METHODS: An annual ongoing prospective study was held in our trauma emergency department (ED) about all the patients who sustained an injury after a recent fall from tree. A questionnaire related to the patient and to the trauma was established. The data were encoded and analysed by a statistical software. RESULTS: One hundred six patients who sustained a fall from tree trauma, out of a total of 139, were studied. Most patients were under 15 years old (76.4 %); they were injured in fruits season (33 %) after a fall from a fruit tree (mango trees, Shea trees, Néré, etc.) and were received late (86 %). Injuries were polymorphic from traumatic brain injuries (51.8 %) and spine injuries (13.2 %) to thoraco-abdominal (21.6 %) and limbs injuries (46.2 %). Three housewives were pregnant at the time of the trauma with secondary abortions. Patients were managed medically (33.9 %), surgically (19.8 %) or by casting (34.9 %) with good outcome in 59 cases. Twelve patients refused medical care and two died. CONCLUSION: Education programs must focus on picking fruits and leaves in order to make them safe and prevent injuries related to these traditional or professional activities.

Amniotic band syndrom at Bobo Dioulasso university teaching hospital (Burkina-Faso): about two cases.

Amniotic band syndrome is a rare congenital disorder. The authors report the first cases documented at Souro Sanou University Hospital in Bobo-Dioulasso (CHUSS) in 2 male new borns. The malformations found at birth, were worn only on limbs and were in the form of skin furrow necking with a major lymphedema downstream. In both cases, the constriction furrow at member pelvic was associated with a club foot and a pseudosyndactyly in one case. Surgical treatment consisted of a section of the constrictor ring and a Z-plasty. The functional outcome was satisfactory with the acquisition of a plantar support for both children. Through these two observations, epidemiological, diagnostic, and particularities of the management of this condition are discussed in the Burkina-Faso.

Associated injuries in patients with facial fractures: a review of 604 patients.

Facial fractures may be associated with concomitant lesions of other parts of body with some of these injuries being life-threatening. This retrospective study reports the types of associated injury and the factors influencing their occurrence, in patients with facial fractures. In 18.2% of 604 patients, one associated injury at least was recorded. The most common associated injury was cranial trauma (9.9%), followed by limbs fractures (9.1%), chest trauma (2%), spine injury (0.5%) and eye ball rupture (0.5%). A poly trauma was recorded in 3.2% of the patients who had sustained a cerebral trauma, a spinal injury or a thoracic trauma. Death occurred in two patients (0.3%) who had respectively a spinal injury and a chest trauma. The occurrence of associated injuries correlated significantly with the fracture type with solitary mandibular fracture being a significant predictor of associated injuries. Although not statistically significant, multiple facial fractures and violence were more associated with concomitant injuries. The findings of this study recall the need for initial full examination of the trauma patients particularly victims of violence, patients presenting with multiple facial fractures or single facial bone fracture involving the mandible, the trauma patients? multidisciplinary management as well as trauma prevention.
