Rib Osteosynthesis for Sub-Acute Management of a Flail Chest in a Tertiary Centre in a Low-Middle Income Country of Sub-Saharan Africa: Case Report at Douala Laquintinie Hospital

Background: Costal fracture surgical is still a debate, therefore we shall select between early and delay surgical management. Case Report: We are reporting two cases of post road traffic clash delay ribs fractures osteosynthesis involving a 63-year-old man with multistage fractures on the left and pulmonary pinning of one of the costal arches, complicated by a homolateral haemothorax and a 41-year-old man with a bilateral flail chest. Conclusion: The simple postoperative course and the immediate postoperative improvement in the patient’s clinical respiratory condition enabled us to discuss the time frame for management, in this case the indication for early or later surgery.

Equalisation of Lower Limb Length in Young Adults Using Internal Osteosynthesis: A Case Report of 22 Patients

Introduction: Inequality in the length of the lower limbs has an impact on the stability and function of the musculoskeletal system because of the imbalance it causes in our bodies. Several treatment modalities were used by practitioners. The aim of this study was to evaluate the anatomical and functional results of length equalisation of the lower limbs using internal osteosynthesis in the Orthopaedic and Traumatological Surgery Department of the Amirou Boubacar Diallo National Hospital in Niamey. Patients and method: This was a retrospective, prospective study of 22 patients from January 2010 to November 2015, a period of 5 years. The patients concerned were aged at least 18 years and had undergone a femoral shortening osteotomy not exceeding 5 cm on the contralateral healthy limb with a screw plate as the internal osteosynthesis device. Results: The average age of our patients was 24.18 years (18 to 48 years). The etiologies of these length inequalities were: vascular 54.55% (n = 12), post-traumatic 27.27% (n = 6), post-infectious 13.64% (n = 3) and neuromuscular 4.54% (n = 1). The mean length inequality of our patients was 4.93 cm, with extremes ranging from 4 to 8 cm. At an average follow-up of 6.5 months (6 to 24 months), our functional results were satisfactory overall. Discussion: Despite the significant nature of our initial inequalities, which were moderate and severe, we ended up with slight inequalities or even total correction for some of our patients. Conclusion: Inequality in the length of the lower limbs is a handicap that requires appropriate management.

Exclusive Fibula Osteosynthesis for Treating Open Fractures Gustillo I-III B of the Distal Half of the Leg Bones in a Resources-Limited Setting

Introduction: Management of open leg bones fractures is a challenging health issue for the surgeon, particularly true in resource-limited settings. In this study, we evaluate exclusive fibular osteosynthesis in the treatment of open fractures of the distal half of the leg bones as a therapeutic option in our context. Methods: This is a prospective, experimental, multicenter study of 30 open fractures of the distal half of the leg bones treated with exclusive fibula osteosynthesis, conducted in 3 hospitals in the DRC from January 1, 2013 to September 30, 2016. Results: The age range of 20 to 40 years grouped 22 (73.4%) patients, the sex ratio was 1:1 and the unemployed were the most involved with 16 (53.3%) cases. The Gustilo II, I, III B and III A types represented 40%, 33.3%, 20% and 6.7%, respectively. The fractures were located in the distal third in 12 (40%) cases, in the middle third in 11 (36.7%) cases, and in both malleoli in 7 cases (23.3%). Osteosynthesis of the fibula by screw plate was applied in 22 (73.3%) patients and pinning in 8 (26.7%). Satisfactory reduction of the tibial fracture site was achieved in 29 (96.7%) cases and 100% bone healing was achieved within an average of 10 weeks. Four (13.3%) loss of alignment, 1 (3.3%) infection, 1 (3.3%) skin necrosis and 2 (6.7%) ankle stiffness complicated our fractures. Conclusion: Exclusive osteosynthesis of the fibula as a common technique for fractures of the distal half of the leg bones allowed us to reduce, immobilize and consolidate the tibial fracture in the required time and to preserve the mobility of the ankle.

Total hip arthroplastyvs. osteosynthesis in acute complex acetabular fractures in the elderly:Evaluation of surgical management and outcomes

Objective: To retrospectively evaluate the open reduction internal fixation and total hip arthroplasty directions, results and complications associated with internal fixation in managing these fractures. <br> Methods: In 8 years at 4 centers, 61 patients with associated acetabular fractures (Letournel classification) were treated. The patients were divided into two groups. The total hip arthoplasty (THA) group consisted of 30 patients, while the open reduction internal fixation group had 31 patients. The average age of the patients was 74.7 years. The following parameters were compared: the duration of surgery and hospitalization, the international unit of red blood cell concentrate transfusion, the time for the verticalization of the patient, perioperative complications, Harris hip score, and the short form (12) health survey. The clinical and radiographic follow-up was performed at 1 month, 3 months, 6 months and 12 months and annually thereafter. Patients with post-traumatic osteoarthritis formed the third comparison group.P≤ 0.05 was considered statistically significant according to the analytical Student’s t-test. <br> Results: TheP < 0.05 in favor of theTHAgroup was: surgical time, length of stay, number of the international unit of red blood cell concentrate transfusions, verticalization, quality of life and hip function, a reduction of perioperative complications and reinterventions. <br> Conclusions: Our experience shows that theTHA treatment for acetabular fractures in the elderly is to be preferred.

An Isolated Displaced Fracture of the Coracoid Process Treated with Osteosynthesis—A Case Report and Review of Literature

Coracoid process fractures are relatively rare and few cases have been reported in the orthopedic literature. In this article, we report the case of an active, thirty years old, male patient with isolated, displaced fracture of the coracoid process, associated with a blunt injury to the shoulder, during a motor vehicle accident. We describe the incidence, mechanism of injury, and surgical treatment. Although rare, a high index of suspicion, special radiographic views, can detect an isolated coracoid process. Knowledge of the associated injuries will help the clinician to order further imaging and treat them accordingly. We recommend that a displaced, isolated fracture of the coracoid be treated with open reduction and osteosynthesis, to achieve early use of the extremity, good radiological union and clinical function.

Osteosynthesis Results of Tibia Plateau Fractures at the Yalgado Ouedraogo University Hospital Center

The sophistication of the implants allows the extension of the surgical indications for tibia plateau fractures. These fractures, which are often comminuted, are caused by a high velocity trauma, making treatment difficult. Objective: The aim of this study was to determine the indications for osteosynthesis of tibia plateau fractures in the orthopaedic-traumatology department of the Yalgado Ouédraogo University Hospital, in order to evaluate the results for their better management. Patients and Methods: it was a 5-year retrospective study of the records of patients with tibia plateau fracture operated and hospitalized in our department. The anatomical-clinical and therapeutic aspects collected from the complete files were analysed. A cortico-cancellous graft was performed in 67.4% of cases. The results were evaluated according to the criteria of Merle d’Aubigné and Mazas [1]. Road traffic accidents (97.4%) were the predominant etiology, involving mainly motorcycles (97.8%). Results: Spino-tuberository and uni-tuberository fractures were the most common. The average consolidation time was 12.5 weeks. One urinary infection, 3 superficial suppurations, 3 vicious calluses and 2 equipment dismantlings were the main complications. Our results were excellent and good in 91.3% and fair in 6.5%. Osteosynthesis of tibial plateau fractures provides excellent results and remains the most appropriate procedure to treat these fractures. Conclusion: reduce the operating time, modernize the technical platform, will allow stable osteosynthesis and early functional rehabilitation to optimize their results.

Anterior Cervical Spine Osteosynthesis Complicated by Pharyngoesophageal Perforation

Anterior cervical spine surgery for traumatic or degenerative disease is a well-established procedure. However, complications such as pharyngoesophageal perforation can occur. In this study, we report a series of 6 pharyngoesophageal perforations after surgery. Based on the literature review, we analyzed pathogenesis, diagnosis and discussed therapeutic strategies. Three cases occurred after surgeries of traumatic cervical spine whereas the remaining were after surgeries for degenerative cervical myelopathy. The mean duration of surgery was 210 minutes. The symptoms, appearing 48 hours after surgery, were commonly hyperthermia, dysphagia, sore throat and swelling of the incision site. The diagnostic was confirmed after contrast-enhanced esophagography. The treatment strategies consisted of insertion of nasogastric feeding tube, oral intake restriction, intravenous antibiotics administration, wound drainage. Reoperation was necessary in 4 cases with removal of the hardware in three of them. One death occurred by pulmonary embolism in a tetraplegic patient. The occurrence of pharyngoesophageal perforation after cervical spine surgery can be disastrous. It can be avoided by increasing surgeon awareness during the surgical procedure. Early detection, immediate and multidisciplinary therapy are recommended to achieve the best outcomes.

Our Experience in the Surgical Treatment of Type C Tibial Pilon Fractures: About 48 Cases

Tibial pilon fractures are rare injuries most often associated with soft tissue injuries, occurring during high-energy trauma. Surgical treatment represents the therapy of choice and must ensure anatomical reconstruction of the joint surface while respecting the surrounding tissues. The evolution of our results showed a majority of good functional clinical radio results by the open treatment which showed its superiority compared to the closed treatment and the combined treatment.

Computer-assisted preoperative planning for proximal humeral fractures by minimally invasive plate osteosynthesis

Background Accurate and precise preoperative planning can provide information instrumental for performing less invasive articular fracture surgery. The purpose of this study was to determine that computer-assisted preoperative planning （CAPP） has the potential to improve efficiency and time in the operating room. Methods Sixty-four patients with proximal humeral fractures were treated using locking plates by minimally invasive plate osteosynthesis （MIPO） with CAPP. The time needed for virtual segmentation, reduction, and fixation of the fracture fragments were recorded. Intra and interobserver reliabilities were analyzed using the intraclass correlation coefficient. The clinical function was analyzed using Constant Score and radiology. Results The mean total time required for CAPP of two-part, three-part, and four-part proximal humeral fractures were （13.63±1.38） minutes, （23.14±2.18） minutes, and （39.61±3.01） minutes, respectively. The intra and interobserver reliabilities for all variables were high, ranging from 0.785 to 0.992. The mean operation time was （50.1±6.7） minutes. Fifty- two patients were followed up with an average time of 34.2 months. The mean Constant Score of the injury side was （82.5 ± 9.9）. Three of the fifty-two patients had four complications. Conclusion The application of CAPP was efficient and reliable, and provided excellent clinical and radiographic outcomes for the treatment of proximal humerus fractures by MIPO.

Evaluation of labial versus labio-inferior lines of osteosynthesis using 3D miniplate for fractures of anterior mandible:A finite element analysis with a pilot clinical trial

Purpose:The fractures of anterior mandible are subject to severe torsional forces due to muscles acting in opposite directions.3D miniplate has been suggested as a good alternative by some researchers.However,finite element model(FEM)studies indicate that labio-inferior positioning of two miniplates perpendicular to each other offers better stability as compared to labial positioning.This study aims at combining the advantages of a single 3D miniplate and labio-inferior positioning of two conventional miniplates,which was assessed by finite element analysis along with a pilot clinical trial.Methods:Two FEM models were created using CT data of a 24-year-old patient with Angie class I occlusion:control model with labial plating and study model with labio-inferior plating.The models were processed with MIMICS.(materialise,Leuven,Belgium),CATIA.(Dassault Systemes)and finite element analysis softwares.Parameters adopted for analysis were(1)displacement(mm)of fracture fragments during each screw fixation,(2)lingual splay and post fixation stability of fracture fragments with masticatory load,and(3)stress distribution(MPa)across fracture fragments.Moreover,a pilot clinical trial including five patients with anterior mandible fracture was conducted.The fractures were managed by intraoral open reduction and 3D miniplate fixation in labio-inferior position.Intraoperative interfragmentary gap,post fixation lingual splay and radiographic fracture union and complications were assessed clinically.Results:Labio-inferior plating demonstrated less displacement(mm)of fracture fragments during screw fixation(0.059 vs.0.079)as well as after application of masticatory load(1.805 vs.1.860).Negligible lingual splay and less stress distribution(MPa)across fracture fragments(1.860 vs.1.847)were appreciated in the study group as compared to control group.Clinical trial support the favorable outcome related to intraoperative and postoperative assessment parameters.Conclusion:FEM analysis and clinical trial reveal better results with labio-inferior positioning of 3D miniplate when compared to labial positioning.

Anterior transolecranon dislocation of the elbow in a child: A case report and review of literature

Anterior transolecranon dislocation of the elbow is rarely observed in children, reported in only a small series. The present case involves an anterior transolecranon dislocation of the left elbow joint in a 7-year-old child, which was surgically treated. Two attempts of closed reduction failed because the radial head had buttonholed via the joint capsule. After its release, open reduction was easily performed; osteosynthesis of the olecranon was not performed. Remarkably, good result was obtained, despite a mild flexion deformity at the last follow-up. This case report aims to highlight this treatment method, which may be considered for such an uncommon injury.

Impact of medial open-wedge high tibial osteotomy for medial compartment osteoarthritis of the knee

BACKGROUND Most populations worldwide,who are used to squatting and sitting cross-legged for their activities of daily living,largely comprise the lower socioeconomic strata,thus making them candidates for exclusion for total knee arthroplasty.Proximal/high tibial osteotomy(HTO)is a preferred strategy for clinically symptomatic osteoarthritis(OA)with genu varum due to painful medial compartment OA which is not amenable to conservative measures.AIM To evaluate the outcomes of medial open-wedge HTO along with autologous bone grafting and buttress plate for the treatment of genu varum due to OA of the knee in a rural population of central India.METHODS A total of 65 knees in 56 patients with a mean age of 58.22±5.63 years with genu varum due to intractable painful knee OA were treated with medial open-wedge HTO along with autologous bone grafting and buttress plate osteosynthesis from June 2015 to May 2018.The mean preoperative radiological angle of genu varum was 13.4°.Clinical outcomes were assessed by the range of movement,knee scores,pain scores,and functional scores.Radiographic studies were performed preoperatively and at regular intervals during the follow-up period.RESULTS All patients reported pain relief immediately after the osteotomy and during the long-term analysis covering between one to three years.The genu varum angle was overcorrected to approximately four degrees in all patients.There was a loss of reduction by approximately three degrees in all patients at around six weeks postoperatively.Preoperative knee movements were restored in all patients.No major perioperative complications were noted during surgery and postoperative follow-up and the clinical scores were significantly improved during the final analysis which revealed good pain relief.CONCLUSION Medial open-wedge HTO is a reliable,safe,practical,physiological,and feasible treatment for populations who are used to increased activity in their occupation and lifestyle and is associated with excellent short-term and long-term results for OA in genu varum knees.

Reattachment of the Osteotomized Greater Trochanter in Hip Surgery Using an Ultrahigh Molecular Weight Polyethylene Fiber Cable: A Multi-Institutional Study

The purpose of this multicenter study was to evaluate the clinical performance of an ultrahigh molecular weight polyethylene (UHMWPE) fiber cable for re-attachment of the osteotomized greater trochanter in hip surgery. Included in the study were 85 hips that had undergone surgery with greater trochanter osteotomy, including 50 hip arthroplasty procedures and 35 hip osteotomies. The osteotomized greater trochanter was reattached using one or more UHMWPE fiber cables. The bone union and displacement of the greater trochanter were assessed in radiographs for up to 12 months after surgery. Non-union of the osteotomy site occurred in 4.7% of the cases. In approximately 90% of the cases, displacement was less than 2 mm at up to 12 months after surgery. The UHMWPE fiber cable was a good biomaterial for reattaching the osteotomized greater trochanter and may also be an option for osteosynthesis procedures.

肱骨近端骨折是老年人继髋部骨折及挠骨远端骨折之后最常见的骨折,由于其骨折类型复杂,大多伴有明显移位或肩袖损伤,治疗不当易导致肩关节不稳及关节僵硬等并发症,是创伤骨科治疗的难点之一。

Derotational osteotomy and internal fixation of a 180°malrotated humerus:A case report

BACKGROUND Humeral shaft fractures are relatively common in adults.Rotational malalignment is reported as one complication but severe rotational deformity of the humerus is extremely rare.To our knowledge,only three cases of symptomatic humeral malrotation have been reported.There are sparse literature reports of humeral reconstruction correction.CASE SUMMARY We present a case of extreme rotational deformity of the humerus(180°)after humeral shaft fracture.The patient complained of pain and difficulties with activities of daily living.In addition,she found the deformity cosmetically unacceptable.Therefore,she was searching for surgical correction.Neurolysis of the radial nerve followed by derotational osteotomy of the humerus and internal fixation were performed.Postoperatively,the patient demonstrated transient iatrogenic radial nerve palsy which recovered completely during postoperative follow-up.The Disabilities of the Arm,Shoulder,and Hand score improved from 55 preoperatively to 16 at the final 2-year follow-up.CONCLUSION Single-stage radial neurolysis,derotational osteotomy and stable fixation is a feasible option to improve anatomic and functional problems of severely malrotated humeral shaft fractures.

Reduction of postoperative bleeding following operative treatment of proximal humerus fractures using a collagen sponge

Aim of the present study is to investigate the efficacy and safety of TachoSil? to reduce afterbleeding and hematoma following operative treatment of proximal humerus fractures. In a prospective randomized study we included a consecutive series of 40 patients with a proximal humeral fracture in this study. All fractures were stabilized surgically with a fixed-angle “Philos plate” from May 2008 through May 2009. All patients were divided in two groups: Group I with plate osteosynthesis without TachoSil, Group II with plate osteosynthesis with TachoSil. For statistical analysis Chi2- Test and U- Test were used. There were 4 perioperative complica- tions in group II and one complication in group I (Chi2-Test: p=0.233). In group II one hardware failure occurred due to osteoporosis requiring revision and reosteosynthesis. Another patient suffered from paralysis of the radial nerve which healed uneventfully. One superficial postopera-tive infection and one superficial hematoma re-quired revision surgery, too. In this group no subfascial hematoma developed. One subfascial hematoma which required no revision occurred in group I. Blood transfusion was required 2 times in group I and 3 times in group II (Chi2-Test: p = 0.549). In sum in group II there was a sig-nificant lower blood loss for the subfascial drain, the region where TachoSil was applied. No ad-verse affects related to TachoSil could be de-tected. TachoSil was found to be safe and effective for reduction of postoperative bleeding following operative treatment of proximal hume-rus fractures. Further studies with larger sample size are required to confirm the efficacy of TachoSil? in orthopedic surgery.

The Recent Development of MIPO in Long Bone Fractures

Minimally invasive plate osteosynthesis (MIPO), which is developed under the guidance of biological osteosynthesis (BO) rules, can achieve faster and better rehabilitation. MIPO is mainly used in long bone fractures such as humerus, tibia and femur, but the technique is distinctive in each fracture site. The operative method, experimental outcome and comparison with other internal fixation methods will be discussed to determine whether MIPO is the best method or alternative method in fracture treatment. Other technique such as less invasive stabilizing system (LISS), which is developed on the basis of MIPO will also be introduced. In this review article, a general view of recent development MIPO is to be given.

Results of Dynamic Interlock Nailing in Distal Tibial Fractures

A study was performed in adults to determine the efficacy of closed reduction and intramedullary nailing in dynamic mode on union, implant failure and incidence of malalignment in patients who sustained an extra-articular fracture of the distal tibia. Methods: Between January 2007 and December 2013, one hundred and twelve patients of distal tibia that involved the distal 6 cm of the tibia were treated at our hospital with reamed intramedullary nailing with use of two distal interlocking screws and one proximal screw in dynamic mode. The augmentation was done with poller screws whenever it was necessary. The nailing of fibular fractures was done in 27 cases. There were 85 males and 27 females with a mean age of 30.9 (range: 20 to 72). Eighty fractures were closed whereas 32 were grade 1 open fractures. Results: The average time to union of the closed fracture was 15.4 weeks (range: 12 – 28 weeks). The healing times for the primarily nailed compound Grade I averaged 17.8 (range: 15 - 34 weeks). After minimum follow-up of one year, rate of primary union was in 97.32%. One case of broken nail required revision surgery. There were three cases of delayed union and two cases of non union. In one case there was deep infection which required exchange nailing with antibiotic impregnated nail. There was breakage of interlocking screws in three cases but fracture had united. In twenty two cases acceptable malalignment of the tibia was observed after union. The outcome was determined at a minimum of one year in our study based on the criteria of Johner and Wruhs. Out of 112 patients, 79 patients had excellent results, 29 had good results and 4 had fair results. Conclusions: The dynamic osteosynthesis of distal tibia by interlocking nail and judicious use of poller screws is an effective alternative for the treatment of distal metaphyseal tibial fractures.

Ankle Arthrodesis in the Treatment of Neglected Ankle Fractures

Introduction: Neglected ankle fractures are common in our regions. Patients first consult traditional healers and it is when the signs persist that they consult the surgeon for a swollen and painful ankle. Initially we always performed anatomical repairs with osteosynthesis, but the majority of patients still complained of pain and disability. We wondered whether a primary arthrodesis would not be indicated in old ankle fractures to avoid disabling pain for patients. We therefore performed a series of arthrodesis on neglected post-traumatic ankles. The objective of our study was to describe the results of arthrodesis on an old post-traumatic ankle and to propose a therapeutic indication in the face of any neglected ankle fracture. Material and Method: This was a prospective study over 8 years between December 2012 and November 2020, involving 36 cases of neglected ankle fractures treated by arthrodesis using Meary’s technique. We used AOFAS (American Orthopedic Foot and Ankle Score) preoperatively and postoperatively for an objective assessment. Results: The average follow-up was 4.2 years and our results were satisfactory (94.4%) with an average AOFAS score ranging from 27.8 preoperatively to 76.7 postoperatively. The fusion rate was 97.2%. Discussion: Arthrodesis appears here as an important alternative in the treatment of neglected ankle fractures with significant trophic disorders.

Lesional and Therapeutic Aspects of Tibial Plateau Fractures at the BSS University Hospital Center in Kati

Introduction: Tibial plateau fractures are solutions of continuity of the epiphyseal-metaphyseal block of the upper end of the tibia of which at least one line enters the joint. They threaten the stability and mobility of the knee and can compromise walking and standing. These fractures are on the increase, especially affecting young and active subjects. Orthopedic treatment is a rare indication apart from non-displaced or slightly displaced forms. Surgical treatment is required in displaced forms, particularly in depression fractures. The aim of this work was to report the lesional and therapeutic aspects of tibial plateau fractures in our department. Patients and Method: Patients and method: This was a retrospective study over 36 months from January 2019 to December 2021. Included in this study were patients treated for a tibial plateau fracture in our department and followed up for at least 10 months. The epidemiological and clinical data analyzed were age, sex, affected side, etiology, mechanism of injury, pathological anatomy and associated lesions. The fractures were classified according to the classification of Duparc and Ficat. The slightly or non-displaced forms were treated orthopedically while the displaced forms were treated surgically. The minimum follow-up was 10 months. The results were evaluated by the anatomical criteria according to Mazas and Duparc and functional according to Merle d’Aubigné. Results: The authors collected 71 cases of tibial plateau fractures. They accounted for 4.0% of all limb fractures, 5.8% of lower limb fractures and 33.8% of knee fractures in our service. The male sex was the most represented at 78.9% with a sex ratio of 3.7. The age group of [20 - 40] years was the most affected, i.e., 53.5%. The average age was 41 years with extremes of 17 and 82 years. The left side was affected (n = 47) and the right side (n = 24). Road traffic accident was the main cause. The mechanism of injury was mainly represented by lateral and sagittal compressions. Lateral unituberosity and bi-tuberosity fractures were the most frequent pathological types in our series, respectively 42.2% and 28.2%. The associated lesions were mainly represented by bone, ligament, skin and neurological lesions. The treatment was orthopedic in 52.1% and surgical in 47.9%. According to the functional criteria of PMA, our results were very good and good at 77.4%, Average at 14.1% and poor at 8.5%. Conclusion: It appears in this study that fractures of the tibial plateaus are frequent and serious because of their articular nature. Lateral and sagittal compressions are the most evoked injury mechanisms. Lateral unituberosity and bituberosity fractures are the most frequent pathological types. Functional and anatomical results are significantly better with surgical treatment.
