Postoperative outcomes of third-generation shoulder hemiarthroplasties for three-and four-part proximal humeral fractures: A systematic review of published studies from 2012 to 2022.

Background: The aim of this study was to provide up-to-date evidence on the outcomes for hemiarthroplasties (HAs) that were performed using modern third-generation prostheses (post-2004) for isolated (excluding head-splits and fracture-dislocations) three-and four-part proximal humerus fractures (PHFs). Methods: PubMed, Medline, Embase and the Cochrane register were searched from January 1, 2012, to November 15, 2022, conforming to the PRISMA guidelines. The outcome measures were the complication rates, revision rates, surgery-related postoperative mortality, post-operative clinical outcome scores and radiological outcomes. Results: 432 hemiarthroplasties in 432 patients were performed across the 11 eligible studies (two prospective and 9 retrospective). Three studies compared HA versus reverse shoulder replacement (RSR); one study compared HA with locking plate fixation (LPF) and RSR; one study compared HA with LPF. 61.1 % and 19.4 % of hemiarthroplasties were performed using cemented and uncemented techniques respectively, while cementing data was ill-defined in 19.4 % of shoulders. The results for the outcome measures have been derived directly from the included studies and no statistical pooling was performed, due to heterogeneity in the different study designs and outcomes. Descriptive data synthesis from the included studies showed that third generation HAs have higher overall postoperative complication rates, with similar revision and mortality rates when compared to RSR and LPF for three-and four-part PHFs. RSR and LPF showed better statistically significant improvements than HA for the Constant-Murley score, Quick DASH, forward flexion and abduction. Mixed results were observed for the DASH score, ASES score and internal rotation ROM between RSR/LPF versus HA. Conclusion: Low to moderate quality evidence from this review showed that even third-generation HA prostheses provided worse overall outcomes than RSR and LPF for three-and four-part PHFs.

Reducing trauma theatre list delays through improved communication between orthopaedic teams and radiographers: A quality improvement project.

AIMS: This quality improvement project was performed to improve delays in starting our trauma theatre lists by implementing measures to improve effective communication between the surgical team and the theatre radiographers. MATERIALS AND METHODS: This was a quality improvement project performed prospectively for 30 orthopaedic trauma lists over two cycles. Only lists requiring fluoroscopy guidance (image intensifier) for the first case were included. Interventions included improvements in use of theatre booking forms with fluoroscopy request checkboxes, dedication of an allocated radiographer for the trauma lists, timely communication of the finalised theatre list order and radiographers participating in the team briefing. RESULTS: Improvements in the timing of fluoroscopy requests and prompt arrival of the radiographer to the theatre were achieved. Furthermore, there was elimination of radiographer-related surgical start time delays following implementation of the interventions. Nevertheless, only minimal improvements were achieved in the participation of the radiographers for the trauma theatre team briefings. CONCLUSION: Although reasons for trauma theatre delays are multifactorial, this quality improvement project has demonstrated that these delays can be reduced through improved communication between radiographers and the orthopaedic team. This is especially important for theatre cases requiring the use of an image intensifier.

Early mobilization following elective ankle lateral collateral ligament reconstruction in adults.

BACKGROUND: Emergency departments in the UK are overwhelmed with musculoskeletal trauma, 50 % of which resulting from ligamentous injuries. Of these, ankle sprains are the most prevalent, however with poor rehabilitation in the recovery period, 20 % of patients may develop chronic instability that may necessitate operative reconstruction. At present, there are no national guidelines or protocols to help direct postoperative rehabilitation and determine weightbearing status. Our aim is to review the existing literature that investigated postoperative outcomes following different rehabilitation protocols in patients with Chronic Lateral Collateral Ligament (CLCL) instability. METHODS: A literature search was performed via Medline, Embase and Pubmed databases using the terms 'ankle', 'lateral ligament', 'repair'. 'reconstruction' and 'early mobilisation'. A total of 19 studies were identified after filtering that they were English language papers. A gray literature search was also performed using the Google search engine. RESULTS: Based on the literature reviewed, patients undergoing early mobilisation and Range Of Movement (ROM) following lateral ligament reconstruction for chronic instability seem to have better functional outcomes and earlier return to work and sports. This is however in the short-term, and there are no medium to long-term studies evaluating the effects of early mobilisation on ankle stability. Furthermore, there may be an increased risk of postoperative complications, mainly wound related, with early mobilization compared to delayed mobilization. CONCLUSION: Further randomized studies and long-term prospective studies with larger cohorts of patients are required to improve the level of evidence available but based on current literature it would appear that controlled early ROM and weight-bearing is advisable in patients undergoing surgery for CLCL instability.

A Closed-Loop Audit for Orthopedic Trauma Operation Notes Comparing Typed Electronic Notes With Handwritten Notes.

Introduction Operation notes are important documents for ensuring patient safety, effective communication between clinicians, and for medicolegal purposes. It is essential that they are clear and accurate. We audited the quality of our operation notes against the Royal College of Surgeons (RCS) of England's Good Surgical Practice Guidelines. Methods This was a prospective audit of 99 orthopedic trauma operation notes. In the first cycle, we audited 58 operation notes for orthopedic trauma surgical procedures. We audited 17 parameters per note. We presented our findings, implemented changes including the use of a typed operation note template, and performed a re-audit using 41 operation notes. Results Our documentation for 3/17 parameters was up to standard in both cycles. Post-intervention, there was an improvement in documentation for 12/17 of the parameters with marked improvements in indication for surgery (45% vs 75%), tourniquet time (20% vs 45%), antibiotic prophylaxis (71% vs 89%), closure technique (62% vs 86%) and detailed postoperative instruction (40% vs 92%). Other parameters, particularly estimated blood loss (7% vs 8%) remained unchanged. In the second cycle, we noted that 25% of the typed notes had 100% compliance with the standards, whereas no handwritten note achieved this. However, there was no statistically significant difference in the mean number of correctly documented parameters between the typed and handwritten notes (p < 0.05). Conclusion The use of operation note templates (preferably typed) can improve appropriate documentation in orthopedic trauma operation notes. These templates should be made easily accessible to all surgeons. We will recommend orthopedic trauma units to apply similar non-rigid templates that can be tailored to suit different categories of trauma surgery.

The Impact of Harm Review Service on Patients Awaiting Elective Orthopaedic Foot and Ankle Surgery for More Than 52 Weeks.

Background and objective There has been a significant increase in waiting times for elective surgical procedures in orthopaedic surgery as a result of the coronavirus disease 2019 (COVID-19) pandemic. As per the hospital policy, patients awaiting elective surgery for more than 52 weeks were offered a consultant-led harm review. The aim of this study was to objectively assess the impact of this service on the field of foot and ankle surgery. Materials and methods The data from harm review clinics at a District General Hospital related to patients waiting to undergo elective foot and ankle procedures in the year 2021 (wait time of more than 52 weeks) were assessed. Clinical data points like change in diagnosis, need for further investigations, and patients being taken off the waiting list were reviewed. The effect of the waiting time on patients' mental health and their perception of the service was assessed as well. Results A total of 72 patients awaiting foot and ankle procedures for more than 52 weeks were assessed as a part of the harm review service. It was noted that 25% of patients found that their symptoms had worsened while 66.1% perceived them to be unchanged. Twelve patients (16.9%) were sent for updated investigations. Twenty-one patients (29.5%) were taken off the waiting lists for various reasons with the most common one being other pressing health concerns; 9% of patients affirmed that the wait for surgery had a significant negative impact on their mental health. Conclusion This study concludes that the harm review service is a useful programme as it helps guide changes in the diagnosis and clinical picture. The service is found to be valuable by most patients, and its impact on the service specialities and multiple centres could be further assessed to draw broad conclusions.

Ultrasonography for the diagnosis of deltoid injury in supination external rotation ankle fractures - A scoping review.

BACKGROUND: Lauge-Hansen supination external rotation (SER)-type ankle fractures are very common and account for up to 75% of all ankle fractures. Assessing deltoid integrity is key for surgical decision making. Ultrasound has been used recently to assess the integrity of the deltoid ligament and differentiate between SER II and SER IV fractures. The aim of this article is to review the literature for studies assessing the diagnostic accuracy of ultrasound in this group of patients. METHODS: After registering the protocol with PROSPERO, Embase, Ovid MEDLINE, Web of Science Core Collection, and Google Scholar were systematically searched. Studies that satisfied the following inclusion criteria were assessed: (1) Adult patients (>16 years), (2) Acute SER-type ankle fractures assessed within 2 weeks of the injury, (3) Diagnostic accuracy studies. Risk of bias assessment was conducted and a narrative synthesis of the results presented. RESULTS: A total of five studies satisfied our inclusion criteria and were included for review. These had a total of 175 patients studied. All studies showed a sensitivity of 100% and specificity of 90-100% for detecting a complete tear of the deltoid. All papers had a significant risk of bias inherent to the design. Only patients undergoing surgery were exposed to the gold standard of operative intervention. CONCLUSION: Ultrasound scan has shown excellent diagnostic accuracy for detecting complete deltoid ruptures in SER ankle fractures. These results however should be interpreted with caution. Perhaps a different approach is needed to assess the efficacy of ultrasound scans in patient with SER type fractures.

Computed Tomography Scan Architectural Measurements in Adult Foot and Ankle Surgery: A Narrative Review for Orthopaedic Trainees.

CT scan plays an important role in adult foot and ankle surgery. Plain radiographs are usually the first-line imaging modality for assessing foot and ankle bone and joint architectural abnormalities. However, despite the fact that a CT scan is more expensive and associated with higher radiation exposure, it offers better imaging quality for the assessment of bony lesions in orthopaedics and trauma. Evidence has shown that more accurate measurements can be obtained from a CT scan compared to plain radiographs. Weight-bearing multi-detection CT scanning goes the extra mile by providing a more detailed assessment, especially for intra-articular fractures, and mirrors the real-life foot and ankle dynamics compared to conventional non-weight-bearing CT scans. It also has a relatively lower radiation dose compared to conventional CT scans. CT scan is the best modality for assessing bony lesions whereas MRI is better for soft tissue pathology. An understanding of the role of CT scan in the anatomical assessment of the foot and ankle will help improve communication between orthopaedic surgeons, radiologists, and radiographers. A thorough understanding of when to use a CT scan compared to the other imaging modalities will also lead to better surgical outcomes, reduced cost, and reduced risk from radiation exposure. This review article analyzes the role of CT in assessing relevant radiographic architectural measurements for diagnosis and surgical planning in adult foot and ankle surgery.

Distal Femoral Replacement as a Primary Treatment Method for Distal Femoral Fractures in the Elderly.

Distal femoral fractures account for 3-6% of all femoral fractures with a similar demographic as patients suffering from proximal femoral fractures. The mortality risk can be high in such injuries, which has prompted NHS England to extend the scope of the Best Practice Tariff to include all fragility fractures of the femur. Poor bone quality, intra-articular extension, and significant comminution can make these fractures difficult to manage with fixation techniques, while early mobilisation is a key outcome in the treatment of this injury. In this study, a comprehensive literature search was performed based on keywords, and abstracts were reviewed to identify relevant articles. The following factors were analysed: time to surgery, time to full weight-bearing, the average hospital stay, post-operative mobility status, and complications. A total of 233 abstracts were identified using the pre-determined search criteria, and, subsequently, articles were excluded following author review. A total of 10 relevant articles were included in this review, with five used for review and comparison between distal femoral replacement (DFR) and fixation. This resulted in a sample of 200 patients treated with DFR with over 87% ambulatory at follow-up and a re-operation rate of 13.3% compared to 78% and 13.5%, respectively, in those treated with open reduction internal fixation (ORIF) procedure. Despite a limited pool of evidence, the literature suggests that DFR offers an option that potentially allows immediate weight-bearing and leaves most patients ambulatory at follow-up. Although DFR is more costly than other operative techniques, it avoids complications associated with fixation such as non-union and can reduce the risk of further surgery through direct complications or a need for delayed arthroplasty, which is deemed more complex secondary to fixation. Early mobilisation is a key step in reducing morbidity and mortality among this cohort of patients, and a procedure such as DFR should be more widely considered to help achieve this outcome.

Treatment strategies for osteochondral lesions of the talus: A review of the recent evidence.

BACKGROUND: There has been no consensus regarding the treatment of osteochondral lesions of the talus, there has been many attempts to formulate a treatment pathway, with multiple proposed modalities and adjuncts used. OBJECTIVES: The aim of this paper was to investigate the evidence published in the recent history, identify the relevant papers, review and summarize the findings, to help clarify the available operative treatment options and their respective efficacies based on the level of evidence provided. STUDY DESIGN & METHODS: A literature search through electronic databases MEDLINE and EMBASE was done, these databases were screened for publications and papers form June 2004 to June 2019. Key words were utilised in the search 'talus, talar, tibia, cartilage, osteochondral, ankle, osteochondritis dissecans, articular cartilage'. Studies on adults aged 18-60 years were included. Exclusion criteria were studies with less than 10 patients, or no clear outcome was recorded. Papers were reviewed by the authors and data extracted as per a pre-defined proforma. RESULTS: Following screening, 28 published articles were included and reviewed. Of these publications 5 were level I, 7 level II, 4 level III and 12 level IV. The total number of patients was 1061 patients. Treatment modalities included arthroscopic microfracture, drilling, hyaluronic acid injection, platelet rich plasma, osteochondral autologous transplantation (OAT), vascularised free bone graft among others. The most common functional measures used to assess efficacy were the Visual analogue scale (VAS) and the American Orthopaedic Foot and Ankle (AOFAS) score. Follow up ranged from 26 weeks upto 4 years. CONCLUSIONS: Despite the abundance of treatment options, high level evidence (level I) remains limited and does not conclude a definitive treatment modality as superior to others. Further research, in the form highly organised randomised clinical trials, is needed to help improve the efficacy and develop new treatment modalities in the future.

The role of interscalene brachial plexus block anaesthesia in arthroscopic shoulder surgery; a prospective study.

The choice of anaesthetic in shoulder surgery is an evolving field of research which has important implications for patient outcomes. We have performed a prospective study to assess the usability of an interscalene brachial plexus block (ISBPB) with sedation as the primary anaesthetic and analgesic for arthroscopic shoulder surgery. Our study assessed the requirements of analgesia peri-operatively and post operatively and found that patients had no requirement (n = 30) and minimal requirements with a low pain score (visual analogue score; mean 2.4, range 2-5) respectively. We also found that patients spent a short amount of time in recovery (31 min mean, range 21-48 min) and were able to be discharged on the same day. Our findings suggest that ISBPB with sedation is a viable option in arthroscopic shoulder surgery for a variety of procedures with positive effects for patient outcomes and mobility.

Delayed Allergic Reaction to ChloraPrepTM in Foot and Ankle Surgery.

Chlorhexidine-based skin preparations are frequently used in orthopaedic surgery. We report 2 recent cases of patients suffering significant allergic reactions to ChloraPrepTM complicating routine foot and ankle surgery. We advise vigilance for this possible issue and recommend thorough removal of all preparation at the end of the procedure.

First metatarsophalangeal fusion using joint specific dorsal plate with interfragmentary screw augmentation: Clinical and radiological outcomes.

BACKGROUND: This study reports the outcome of a plating system for arthrodesis of the first metatarsophalangeal joint (1st MTPJ) that incorporates a lag compression screw within a low profile titanium plate with a predetermined contour. This is the first report of the outcomes of this implant from a non-affiliated centre. PATIENT AND METHODS: This is a prospective cohort study of 40 consecutive primary 1st MTPJ arthrodesis procedures. The mean age of the cohort was 56 years (range, 20-74 years). The diagnosis was hallux rigidus in 31 patients and inflammatory arthropathy in 7 patients. RESULTS: All patients achieved clinical union at 6 weeks and radiological union was confirmed on plain radiographs between 6-16 weeks. One case of hardware removal was reported. CONCLUSION: The cohort achieved consistently satisfactory results with a reliable and reproducible MTPJ position and a 100% union rate. There was a low rate of hardware removal. LEVEL OF EVIDENCE: Level IV evidence. Prospective cohort study.

Fractures of the anterior process of the calcaneum; a review and proposed treatment algorithm.

BACKGROUND: There remains a lack of recognition of these fractures, which leads to a delay in diagnosis and appropriate management. METHODS: A comprehensive literature search was performed. Following inclusion and exclusion criteria, 23 studies were available for analysis. RESULTS: Delay in diagnosis is common and has a negative impact on outcome. If an APC fracture is suspected; anteroposterior, lateral and oblique plain radiographs should be requested. Further investigation with computed tomography or magnetic resonance imaging is indicated if plain radiographs are inconclusive and patient remains symptomatic. Non-operative measures are usually adequate for most undisplaced fractures, however surgical intervention maybe required for large, intra-articular fractures in the acute setting and for non-union. CONCLUSIONS: A treatment algorithm is suggested that may help with the diagnosis and management of these injuries. LEVEL OF EVIDENCE: Level IV.

Dedifferentiated Chondrosarcoma Demonstrating Osteosarcomatous Differentiation.

BACKGROUND: Dedifferentiated chondrosarcoma (DDC) accounts for a small proportion of chondrosarcomas. They demonstrate aggressive behaviour with a high rate of local recurrence and systemic progression resulting in poor long-term survival rates. Due to its relatively low incidence, previous studies have grouped different histiotypes together to achieve adequate study numbers for analysis. METHODS: This retrospective study examines the clinical course and the role of chemotherapy in the subgroup of patients with DDC where osteosarcoma is the predominant dedifferentiated component. Between 2000-2010, 21 patients were identified. RESULTS: The mean age at presentation was 64 years (range 35-80 years). 12 patients were considered unfit for chemotherapy, whilst 2 patients declined chemotherapy. 5 patients received neoadjuvant chemotherapy, with less than 90% necrosis demonstrated in all these cases. 3 patients received post-operative chemotherapy. The median survival for the entire group was 9.5 months. In the 7 patients who received chemotherapy, the median survival was 17 months, and those who had chemotherapy had a greater median time to local recurrence. CONCLUSION: This study demonstrates that cytotoxic chemotherapy may be offered to appropriately selected patients.

The management of dorsal peroneal nerve compression in the midfoot.

The foot and ankle specialist will frequently encounter patients with dorsal midfoot pain in clinic. In the presence of midfoot pain and/or paraesthesia, nerve entrapment must be considered. The authors report the outcome of a case series of patients who underwent surgical release of the DPN. Between 2011-2017, a single surgeon operated on seven patients with a diagnosis of DPN entrapment. A retrospective review of the patient's clinical notes was performed, including the operative findings. The average age at presentation was 47 years (range, 31-70 years), and the left foot was affected in four cases. In all cases the patient presented with dorsal midfoot pain, with three cases associated with paraesthesia. The mean follow up was 25 months (range, 4-70 months), with six of the patients discharged with their pre-operative symptoms settled. One patient who had good immediate pain relief following DPN neurolysis, EHB tendon resection and reduction of exostosis developed recurrence of the neuropathic pain at five years. Despite non-operative management the symptoms did not settle and exploration of the DPN was performed. The anatomical position of the DPN, and its site of compression, may vary however it can be localised by a positive Tinel's sign and targeted injection with local anaesthetic. All the patients that underwent surgical exploration and decompression had a good outcome, with one patient requiring further neurolysis for impingement.

Does the surgery time affect the final outcome of type III supracondylar humeral fractures?

INTRODUCTION: Supracondylar humeral fractures are common in the pediatric population, with displaced fractures requiring operative intervention. The purpose of this study was to look at our practice and assess whether a difference in clinical outcomes and requirement for open reduction was observed if surgery was delayed. METHODS: This was a retrospective medical record and plain radiograph review of patients admitted with type III Gartland supracondylar fractures between January 2014 and December 2015. The patients were seen for up to 12 months postoperatively, and clinical assessment was performed at this stage. RESULTS: There were 116 supracondylar humeral fractures admitted between January 2014 and December 2015, 23 of which were Gartland type III. The mean age of the patients was 6 years, and the mean time from emergency department presentation to surgery was 14 h. Seven of the 23 patients required conversion to open reduction. There were no reported complications and all fractures demonstrated radiographic union. The length of time to surgery did not increase the number of cases requiring open reduction. The results demonstrated that there was no difference in clinical outcomes found between those that had closed manipulation or required conversion to open reduction, nor the time taken to surgery. CONCLUSION: This study suggest that patients who present with type III supracondylar humeral fractures and have no neurovascular deficit, a delay in pinning of 12 h or more may not result in a significant difference in the need for open reduction or clinical outcomes. LEVEL OF EVIDENCE: Level IV.

Tissue Engineering in Achilles Tendon Reconstruction; The Role of Stem Cells, Growth Factors and Scaffolds.

BACKGROUND: Achilles tendon injuries are common, and present a challenge in the acute and chronic setting. There is significant morbidity associated with the injury and the numerous management strategies, as well as financial implications to the patient and the health service. To date, repair tissue from all methods of management fail to achieve the same functional and biomechanical properties as the native tendon. OBJECTIVE: The use of tissue engineering technology may reduce morbidity, improve the biomechanical properties of repair tissue and reduce the financial burden. The goal is to produce completely integrated tendon repair tissue that has the functional and mechanical properties of the native tendon. This review evaluates the role of stem cells in tissue engineering for tendon reconstruction and the various sources for harvesting stem cells. RESULTS: They can be obtained from the embryo, foetus or adult, and require the correct conditions for proliferation and differentiation. There remain many ethical concerns with the use of embryo or foetus harvested stem cells, thus the focus remains on adult sources, haematopoietic and non-haematopoietic. The improving knowledge of the role of growth factors is addressed, as is their effect on animal models for tendon repair. Growth factors include bone morphogenic proteins, transforming growth factor ., insulin-like growth factor and platelet derived growth factor. The role of scaffolds in human and animal models is reviewed, both naturally derived and synthetic scaffolds. Whilst numerous animal studies have reported encouraging results, further work is required. CONCLUSIONS: The ideal source of MSCs still has not been agreed upon, and little is known regarding the signalling pathways involved in tenogenesis of MSCs. Whilst current studies have shown encouraging results with regards to improved biomechanical and histological properties, further work is required to ascertain the growth factors, biomaterials and source of stem cells required for tendon regeneration.

The Role of 3D Modelling and Printing in Orthopaedic Tissue Engineering: A Review of the Current Literature.

Orthopaedic surgery lends itself well to advances in technology. An area of interest and ongoing research is that of the production of scaffolds for use in trauma and elective surgery. 3D printing provides unprecedented accuracy in terms of micro- and macro-structure and geometry for scaffold production. It can also be utilised to construct scaffolds of a variety of different materials and more recently has allowed for the construction of bio-implants which recapitulate bone and cartilage tissue. This review seeks to look at the various methods of 3DP, the materials used, elements of functionality and design, as well as modifications to increase the biomechanics and bioactivity of 3DP scaffolds.

Does a dedicated orthopaedic day surgery list improve delivery of trauma services?

Our aim was to implement a 23-hour pathway for uncomplicated trauma to overcome delays and improve efficiency. A retrospective review of a single surgeon series of 105 consecutive patients operated on between July 2010 and July 2011 was performed. With recently revised trauma tariffs, we believe an efficient day surgery trauma list improves theatre utilisation, reduces inpatient bed demands, prioritises major and sub-specialist trauma and delivers patient satisfaction.
