Midcarpal Impaction Syndromes as a Rare Cause of Ulnar-Sided Wrist Pain: A Review.

Ulnar-sided wrist pain remains a commonly encountered diagnostic challenge, and its successful management requires a comprehensive understanding of the multiple conditions that can present with this symptom. Midcarpal impaction syndromes in the form of Hamato-lunate and Triquetro-hamate impingement have both previously been reported as rare potential causes of ulnar-sided wrist pain. Despite this, they remain poorly recognized and incompletely understood. This article reviews existing literature that describes the diagnosis and management of these clinical entities.

Outcome following management of unstable lateral end clavicle fractures with locking plate and coracoid anchor augmentation.

Background: Management of complex lateral end clavicle fractures with coraco-clavicular ligament disruption can be challenging. Methods: We prospectively analysed 19 (17 M:2F) patients from January 2014 to June 2016. Six patients had intra-articular fractures (Edinburgh-3B2) and the remaining were extra-articular (3B1). All patients had open reduction internal fixation with lateral end locking plate augmented with a coracoid anchor. All patients were evaluated at the final follow-up by American Shoulder and Elbow Surgeon score (ASES), Disabilities of the Arm, Shoulder and Hand (DASH), Oxford Shoulder Score (OSS), return to work, sports and radiographs. Results: At a mean follow-up of 54 months (range 37-64), 19 patients were available for analysis. Mean age of patients was 34 years (range 24-65). At final follow-up DASH score was 1.66 (range 0-5); ASES score was 98.14 (93.3-100) and OSS was 46.6 (42-48). There was no difference in the functional outcome between 3B1 and 3B2 fractures (DASH - p(0.51); ASES - p(0.44); OSS - p(0.69)). All patients returned to preinjury level of function, sports and work. Five patients needed implant removal and three developed capsulitis that resolved with conservative treatment. Conclusion: Locking plate fixation, augmented with coracoid anchor is an effective option in the management of these complex injuries. The need for implant removal is reduced (26%) and there is no difference in the functional outcome between 3B1 and 3B2 fractures.

Management of open elbow fractures: experiences and outcomes from a UK major trauma center.

HYPOTHESIS AND BACKGROUND: Open fractures about the elbow are an infrequent but complex injury with limited existing literature. The aims of the study were to review the treatment strategies of open elbows fractures, functional outcome and complication rates associated with the injury, and correlate the outcome with the topography of the fracture. METHODS: Patients (n = 21) with open elbow fractures injuries over a 2-year period were analyzed. They were assessed regarding the orthoplastic characteristics of their injury as well any other associated injuries. Outcomes were assessed objectively (achievement of bony union, range of movement, infection status, need for further procedures) and subjectively (Oxford Elbow Score, EQ-5D, EQ-VAS). RESULTS: The commonest grade of open injury was grade 3 (43%). Associated orthopedic injuries were present in 62% and associated system injuries in 57%. Almost half of the patients were noted to have had a significantly increased presenting mortality risk as per Injury Severity Score assessment. Mean time to first wound débridement was 31 hours. There were no cases of deep or chronic infection. Complete bony union was noted in 85% of patients, and 48% of patients required removal of metalwork. Subgroup analysis of the cohort by fracture topography (single unipolar elbow bone injury vs. multiple elbow bony injuries) demonstrated no significant difference (P > .05) regarding rate of complication or final Oxford Elbow Score, EQ-5D or EQ-VAS. Patients with injuries that involved the distal humerus had the highest rate for further procedures (P < .05). The average Oxford Elbow Score, EQ-5D, and EQ-VAS scores for the whole cohort at final follow-up were 37.4, 0.54, and 62.18, respectively. DISCUSSION: Open elbow injuries are usually from high-energy trauma and often combined with other significant injuries. As a result, the timelines to elbow surgery were often delayed. However, this did not impact the local infection rates nor did it necessitate further surgery, but made achieving all British Orthopaedic Association Standards for Trauma targets difficult. Chronic infection was not an issue in this cohort. Subgroup analysis indicates open distal humerus fractures carry the highest risk for further procedures. This is most commonly in the form of removal of metalwork and fibrinolysis. End outcomes for patients with open elbow fractures can be positive, despite the notable presenting Injury Severity Score. A subspecialist elbow and orthoplastic approach whenever possible is advocated.

Theatre efficiency in COVID-19 pandemic conditions: The collaborative experience of four level 1 major trauma centres in the UK.

AIMS: As the world continues to fight successive waves of COVID-19 variants, we have seen worldwide infections surpass 100 million. London, UK, has been severely affected throughout the pandemic, and the resulting impact on the NHS has been profound. The aim of this study is to evaluate the impact of COVID-19 on theatre productivity across London's four major trauma centres (MTCs), and to assess how the changes to normal protocols and working patterns impacted trauma theatre efficiency. METHODS: This was a collaborative study across London's MTCs. A two-month period was selected from 5 March to 5 May 2020. The same two-month period in 2019 was used to provide baseline data for comparison. Demographic information was collected, as well as surgical speciality, procedure, time to surgery, type of anaesthesia, and various time points throughout the patient journey to theatre. RESULTS: In total, 1,243 theatre visits were analyzed as part of the study. Of these, 834 patients presented in 2019 and 409 in 2020. Fewer open reduction and internal fixations were performed in 2020 (33.5% vs 38.2%), and there was an increase in the number of orthoplastic cases in 2020 (8.3% vs 2.2%), both statistically significant results (p < 0.000). There was a statistically significant increase in median time from 2019 to 2020, between sending for a patient and their arrival to the anaesthetic room (29 vs 35 minutes; p = 0.000). Median time between arrival in the anaesthetic room and commencement of anaesthetic increased (7 to 9 minutes; p = 0.104). CONCLUSION: Changes in working practices necessitated by COVID-19 led to modest delays to all aspects of theatre use, and consequently theatre efficiency. However, the reality is that the major concerns of impact of service did not occur to the levels that were expected. Cite this article: Bone Jt Open 2021;2(10):886-892.

Updates on Distal Radius Fractures Past, Present, and Complications.

Before the 1900s, distal radius fractures were misdiagnosed as radiocarpal dislocations and most were treated nonoperatively. Between the 1900s and 1920s there were several anesthesia and antiseptic advancements that led to the advancement of surgical interventions. Then after the continued use and implementation of radiographs in orthopedics, radiographic parameters allowed for a critical analysis of treatment and patient outcomes that led to the further advancement of distal radius fracture treatment. This review will detail the historical content that led us to current practices. Additionally, current methods are critiqued, and common complications are reviewed in order to allow orthopedic surgeons to avoid these complications today.

Outcomes of orthopaedic trauma patients undergoing surgery during the peak period of COVID-19 infection at a UK major trauma centre.

BACKGROUND: To review the clinical outcomes of all patients undergoing emergency orthopaedic trauma surgery at a UK major trauma centre during the first 6 weeks of the COVID-19 related lockdown. METHODS: A retrospective review was performed of all patients who underwent emergency orthopaedic trauma surgery at a single urban major trauma centre over the first six-week period of national lockdown. Demographics, co-morbidities, injuries, injury severity scores, surgery, COVID-19 status, complications and mortalities were analysed. RESULTS: A total of 76 patients were included for review who underwent multiple procedures. Significant co-morbidity was present in 72%. The overall COVID-19 infection rate of the study population at any time was 22%. Sub-group analysis indicated 13% had active COVID-19 at the time of surgery. Only 4% of patients developed COVID-19 post surgery with no mortalities in this sub-group. The overall mortality rate was 4%. The overall complication rate was 14%. However mortality and complications rates were higher if the patients had active COVID-19 at surgery, if they were over 70 years and had sustained life-threatening injuries. CONCLUSION: The overall survival rate for patients undergoing emergency orthopaedic trauma surgery during the COVID-19 peak was 96%. The rate of any complication was more significant in those presenting with active COVID-19 infections who had sustained potentially life threatening injuries and were over 70 years of age. Conversely those without active COVID-19 infection and who lacked significant co-morbidities experienced a lower complication and mortality rate.

Variation in the clinical commissioning of surgery for three common hand conditions in England.

The surgical referral policies for patients with trigger finger, ganglion removal and Dupuytren's disease were collected for all Clinical Commissioning Groups in England. The aim was to assess whether there was variation in the policies across England, resulting in inequality in patients' access to surgery. Data were collected between October 2018 and January 2019 and compared with national guidelines. Analysis of the results showed that for all three conditions, surgical commissioning policies varied depending on the locality. The results also show that despite the existence of national guidelines, they are not implemented. This has the potential to lead to variation in surgical referral and access to services for patients in different localities in England.Level of evidence: III.

Reflections from London's Level-1 Major Trauma Centres during the COVID crisis.

Emergence of the Covid-19 pandemic resulted in dramatic changes in global healthcare provision. Resources were redirected across all healthcare sectors to support the treatment of viral pneumonia with resultant effects on other essential services. We describe the impact of this on the provision of major trauma care in a major capital city.

Functional Outcomes Following Pilon Fractures of the Middle Phalanx Managed with the Ligamentotaxor External Fixator.

BACKGROUND: The surgical aims in managing displaced intra-articular fractures of the base of the middle phalanx include early joint reduction, maintaining congruence and early mobilization. Achieving this can be a challenge. However dynamic external fixators offer a solution. The study aim was to evaluate the use and outcomes of the Ligamentotaxor external fixator in patients with such injuries. METHODS: A total of 12 patients were managed with this device and outcomes were assessed. All patients reached clinical and radiological union. RESULTS: An average range of movement to the proximal interphalangeal joint of 63° was noted along with an average end of care-cycle quick-DASH score of 9.1. Two patients developed pin-site infections. CONCLUSIONS: The outcomes seen support the use of the Ligamentotaxor in the management of middle phalanx intra-articular fractures. It is simple to apply, potentially avoids the secondary complications of open reduction and gives reproducible results. However judicious patient selection is advised.

The Interlocking Modification of the Cross Locked Cruciate Tendon Repair (Modified Adelaide Repair): A Static and Dynamic Biomechanical Assessment.

The 4-strand cross-locked cruciate flexor tendon repair technique (Adelaide technique) has been shown to have comparably high resistance to gap formation and ultimate tensile strength. This study aimed to determine whether an interlocking modification to the Adelaide repair would impart improved biomechanical characteristics. Twenty four sheep flexor tendons were harvested, transected and repaired using either standard or modified Adelaide techniques. Repaired tendons were cyclically loaded. Gap formation and ultimate tensile strength were measured. Additionally, suture exposure on the tendon surface was determined. There was a statistically significant increase in resistance to gap formation in the early phase of cyclic loading within the modified Adelaide group. In the later stages of testing no significant difference could be noted. The average final load to failure in the modified group was higher than the standard group but this did not achieve statistical significance. Interlocking suture techniques in four strand tendon repair constructs can improve gapping behavior in the early phase of cyclic loading.

Management of heterotopic ossification and restricted forearm rotation after tension band wiring for olecranon fracture.

A 32-year-old lady presented to our clinic with persistent painful restriction of her dominant forearm movements for three months after tension band wiring of olecranon. She had full elbow flexion and extension; however, her forearm rotations were restricted and painful. Investigations revealed prominent tips of the wire, eroding the radial tuberosity with heterotopic ossification between the radius and ulna. As there was no synostosis, the patient had implant exit. During surgery, before implant removal, examination under anaesthesia revealed a mechanical block of the rotation beyond 30° on pronation and supination from neutral. However, after the removal of implant, the mechanical block eased off and with gentle manipulation, full pronation and supination were achieved. At the final follow-up at 6 months, the patient had full pain-free forearm rotation with regression of heterotopic ossification. Our case report highlights the importance of intra-operative assessment of wire tips at full supination and pronation, and in patients with restricted forearm rotation, CT scan may be needed to assess the position of the hardware is essential as it can progress to synostosis. In cases with prominent hardware, removal of the implant may suffice if performed before the development of synostosis.

Intra-abdominal pectus bar migration--a rare clinical entity: case report.

We present the case of a 20-year-old male who underwent successful surgical correction of pectus excavatum with the Highly Modified Ravitch Repair (HMRR). At 29 months the attempted operative removal of the Ravitch bar was unsuccessful despite the impression of adequate bar location on chest x-ray. Subsequent imaging with computed tomography was unclear in determining whether the bar was supra or infra-diaphragmatic due to the tissue distortion subsequent to initial surgery. Video assisted thoracoscopic surgery (VATS) successfully retrieved the bar and revealed that it was not in the thorax, but had migrated to the intra-abdominal bare area of the liver, with no evidence of associated diaphragmatic defect or hernia. Intra-abdominal pectus bar migration is a rare clinical entity, and safe removal can be facilitated by the use of the VATS technique.
