Aims

Medial humeral epicondyle fractures (MHEFs) are common elbow fractures in children. Open reduction should be performed in patients with MHEF who have entrapped intra-articular fragments as well as displacement. However, following open reduction, transposition of the ulnar nerve is disputed. The aim of this study is to evaluate the need for ulnar nerve exploration and transposition.

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.

Aims. Distal third clavicle (DTC) fractures are increasing in incidence. Due to their instability and nonunion risk, they prove difficult to treat. Several different operative options for DTC fixation are reported but current evidence suggests variability in operative fixation. Given the lack of consensus, our objective was to determine the current epidemiological trends in DTC as well as their management within the UK. Methods. A multicentre retrospective cohort collaborative study was conducted. All patients over the age of 18 with an isolated DTC fracture in 2019 were included. Demographic variables were recorded: age; sex; side of injury; mechanism of injury; modified Neer classification grading; operative technique; fracture union; complications; and subsequent procedures. Baseline characteristics were described for demographic variables. Categorical variables were expressed as frequencies and percentages. Results. A total of 859 patients from 18 different NHS trusts (15 trauma units and three major trauma centres) were included. The mean age was 57 years (18 to 99). Overall, 56% of patients (n = 481) were male. The most common mechanisms of injury were simple fall (57%; n = 487) and high-energy fall (29%; n = 248); 87% (n = 748) were treated conservatively and 54% (n = 463) were Neer type I fractures. Overall, 32% of fractures (n = 275) were type II (22% type IIa (n = 192); 10% type IIb (n = 83)). With regards to operative management, 89% of patients (n = 748) who underwent an operation were under the age of 60. The main fixation methods were: hook plate (n = 47); locking plate (n = 34); tightrope (n = 5); and locking plate and tight rope (n = 7). Conclusion. Our study is the largest epidemiological review of DTC fractures in the UK. It is also the first to review the practice of DTC fixation. Most fractures are being treated nonoperatively. However, younger patients, suffering a higher-energy mechanism of injury, are more likely to undergo surgery. Hook plates are the predominantly used fixation method followed by locking plate. The literature is sparse on the best method of fixation for optimal outcomes for these patients. To answer this, a pragmatic RCT to determine optimal fixation method is required.

Aims. The morphology of medial malleolar fracture is highly variable and difficult to characterize without 3D reconstruction. There is also no universally accepeted classification system. Thus, we aimed to characterize fracture patterns of the medial malleolus and propose a classification scheme based on 3D CT reconstruction. Methods. We retrospectively reviewed 537 consecutive cases of ankle fractures involving the medial malleolus treated in our institution. 3D fracture maps were produced by superimposing all the fracture lines onto a standard template. We sliced fracture fragments and the standard template based on selected sagittal and coronal planes to create 2D fracture maps, where angles α and β were measured. Angles α and β were defined as the acute angles formed by the fracture line and the horizontal line on the selected planes. Results. A total of 121 ankle fractures were included. We revealed several important fracture features, such as a high correlation between posterior collicular fractures and posteromedial fragments. Moreover, we generalized the fracture geometry into three recurrent patterns on the coronal view of 3D maps (transverse, vertical, and irregular) and five recurrent patterns on the lateral view (transverse, oblique, vertical, Y-shaped, and irregular). According to the fracture geometry on the coronal and lateral view of 3D maps, we subsequently categorized medial malleolar fractures into six types based on the recurrent patterns: anterior collicular fracture (27 type I, 22.3%), posterior collicular fracture (12 type II, 9.9%), concurrent fracture of anterior and posterior colliculus (16 type III, 13.2%), and supra-intercollicular groove fracture (66 type IV, 54.5%). Therewere three variants of type IV fractures: transverse (type IVa), vertical (type IVb), and comminuted fracture (type IVc). The angles α and β varied accordingly. Conclusion. Our findings yield insight into the characteristics and recurrent patterns of medial malleolar fractures. The proposed classification system is helpful in understanding injury mechanisms and guiding diagnosis, as well as surgical strategies. Cite this article: Bone Joint J 2021;103-B(5):931–938

Aims

To evaluate the outcomes of terrible triad injuries (TTIs) in mid-term follow-up and determine whether surgical treatment of the radial head influences clinical and radiological outcomes.

Aims

It has been generally accepted that open fractures require early skeletal stabilization and soft-tissue reconstruction. Traditionally, a standard gauze dressing was applied to open wounds. There has been a recent shift in this paradigm towards negative pressure wound therapy (NPWT). The aim of this study was to compare the clinical outcomes in patients with open tibial fractures receiving standard dressing versus NPWT.

Aims. We aimed to evaluate the health-related quality of life (HRQoL) in children with supracondylar humeral fractures (SCHFs), who were treated following the recommendations of the Paediatric Comprehensive AO Classification, and to assess if HRQoL was associated with AO fracture classification, or fixation with a lateral external fixator compared with closed reduction and percutaneous pinning (CRPP). Methods. We were able to follow-up on 775 patients (395 girls, 380 boys) who sustained a SCHF from 2004 to 2017. Patients completed questionnaires including the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH; primary outcome), and the Pediatric Quality of Life Inventory (PedsQL). Results. An AO type I SCHF was most frequent (327 children; type II: 143; type III: 150; type IV: 155 children). All children with type I fractures were treated nonoperatively. Two children with a type II fracture, 136 with a type III fracture, and 141 children with a type IV fracture underwent CRPP. In the remaining 27 children with type III or IV fractures, a lateral external fixator was necessary for closed reduction. There were no open reductions. After a mean follow-up of 6.3 years (SD 3.7), patients with a type I fracture had a mean QuickDASH of 2.0 (SD 5.2), at a scale of 0 to 100, with lower values representing better HRQoL (type II: 2.8 (SD 10.7); type III: 3.3 (SD 8.0); type IV: 1.8 (SD 4.6)). The mean function score of the PedsQL ranged from 97.4 (SD 8.0) for type I to 96.1 (SD 9.1) for type III fractures, at a scale of 0 to 100, with higher values representing better HRQoL. Conclusion. In this cohort of 775 patients in whom nonoperative treatment was chosen for AO type I and II fractures and CRPP or a lateral external fixator was used in AO type III and IV fractures, there was equally excellent mid- and long-term HRQoL when assessed by the QuickDASH and PedsQL. These results indicate that the treatment protocol followed in this study is unambiguous, avoids open reductions, and is associated with excellent treatment outcomes.

Aims

The aim of this study was to clarify the factors that predict the development of avascular necrosis (AVN) of the femoral head in children with a fracture of the femoral neck.

Aim. Infection rates after management of open fractures are still high. Existing guidelines regarding prevention of this complication are inhomogeneous. A survey directed to orthopaedic trauma surgeons worldwide aims to give an overview of current practices in the management of open fractures. Method. An international group of trauma surgeons and infection specialists with experience in the field of musculoskeletal infections developed a questionnaire that was distributed via email to all AOTrauma members worldwide. Descriptive statistical analysis was performed. Results. 1197 orthopaedic trauma surgeons answered the survey (response rate: 4,9% of all opened emails). Cephalosporins are the most commonly used antibiotics for systemic prophylaxis in open fractures (cefazolin: 51,46% cefuroxime: 23,6%, ceftriaxone: 14,54%). In Gustilo type III open fractures gentamicin (49,12%) and metronidazole (33,58%) are often added. 86% (n=1033) reported to give the first dosage of systemic antibiotics in the emergency department as soon as the patient arrives. Only 3% (n=34) reported pre-hospital administration at the scene of the accident or during transport to the hospital. While most respondents administer antibiotics over 24h in type I open fractures (34%, n=405), for type II open fractures the most often mentioned duration is 72h (26%, n=306). For type III a 7 days course was most often performed (38%, n=448). Overall, there is a tendency to longer durations with increasing severity. However, a vast majority agreed that the optimal duration is not well defined in the literature (71%, n=849). 20psi,”Jet-Lavage”). The amount of irrigation fluid has a bimodal distribution with two peaks at 4–6 liters (24%, n=286) and at 8–10 liters (24%, n=282). Conclusions. Results from our survey give an overview of current practices and identify certain aspects in the management of open fractures where treatment protocols are very heterogenous and guidelines not well accepted. These controversies demand for further research in this field to provide better evidence

Background. As the number of primary or revision TKA with stem extension cases are growing simultaneously, the number of periprosthetic fracture in these cases has also increased accordingly. However, there have been few reports on the classification and treatment of periprosthetic fracture following stemmed TKA and lack of information about the treatment outcome. The purposes of this study were 1) to demonstrate classification and management of periprosthetic fractures after stemmed TKA and 2) to report treatment outcome after the periprosthetic fractures. Materials and Methods. This retrospective study included 17 knees (15 patients) with an average age of 69.7 years. All cases were revision TKA cases, and there were 13 female and 2 male patients. The patients were treated nonoperatively or underwent operation by orthopedic principle. The period of union was evaluated by confirming the formation of callus crossing fragments in radiographs. We reviewed the complications and functional outcomes after treatment of periprosthetic fracture following revision TKA by assessing FF, FC and scoring WOMAC and KSS. Results. The classification of periprosthetic fractures of stemmed TKA was based on location of fracture and stability of implant. They were classified as follows: type I, metaphyseal fracture without loosening of implant [Fig. 1]; type II, diaphyseal fracture adjacent to stem without loosening of implant [Fig. 2]; type III, diaphyseal fracture away from stem without loosening of implant [Fig. 3]; and type IV, metaphyseal or diaphyseal fracture with loosening of implant [Fig. 4]. There were 1 case of type I, 9 cases of type II, 4 cases of type III and 3 cases of type IV fractures. The mean time for gaining radiographic union of type I was 3.3 month; type II was 4.4 month; type III was 4.6 month; and type IV was 3.9 month. Most of the metaphyseal fractures were comminuted and all cases of loosening of the femoral implant were found in the metaphyseal fractures. Nine periprosthetic fractures were fixed using locking plate (single locking plate : 4 cases, dual locking plate : 5 cases). The bone union period is much shorter in patients with dual plate fixation than single plate only. Range of motion, WOMAC and KSS were not significantly different between before fracture and after management of fracture. Complications included 1 metal failure, 2 loosening of implant and 1 postoperative infection. Conclusions. Metaphyseal fractures probably cause the collateral ligament insufficiency, and loosen the implant. Therefore, rotating hinge prosthesis should be used to stabilize the ligament of knee joint. Also, Revision TKA with longer stem should be considered if the stability of implant is not sure. When we underwent operation using plate fixation, dual plating provided better stability of fracture and shortened the union period than single plating. However, we need to approach individually depending on the patient, such as using cerclage wire, bone graft and so on. This study will help to establish appropriate treatment options according to each classification. For any figures or tables, please contact the authors directly
