RESUMO
BACKGROUND: Total ankle replacement is an established treatment for end-stage arthritis. However, there is little data examining outcomes in sequential bilateral replacements. This study aimed to compare outcomes between first and second ankles in sequential replacement. METHODS: Patients were retrospectively contacted to complete a follow-up questionnaire including the Manchester-Oxford Foot Questionnaire (MOXFQ), EQ-5D-3 L, and a question assessing satisfaction. Electronic records identified demographics, procedural details, and complications. RESULTS: Twenty patients underwent sequential bilateral ankle replacement over the study period. At a mean follow-up of four years, 18 patients completed the follow-up questionnaire. There was no statistically significant difference between first and second ankles in terms of MOXFQ score, EQ-5D-3 L or satisfaction. Eleven complications were noted. CONCLUSIONS: We report excellent outcomes after sequential bilateral ankle replacement with no difference in outcomes between first and second ankles. These results can be used to counsel patients in the future and manage expectations. LEVEL OF EVIDENCE: IV.

AIMS: To develop a reliable and effective radiological score to assess the healing of isolated ulnar shaft fractures (IUSF), the Radiographic Union Score for Ulna fractures (RUSU). METHODS: Initially, 20 patients with radiographs six weeks following a non-operatively managed ulnar shaft fracture were selected and scored by three blinded observers. After intraclass correlation (ICC) analysis, a second group of 54 patients with radiographs six weeks after injury (18 who developed a nonunion and 36 who united) were scored by the same observers. RESULTS: In the initial study, interobserver and intraobserver ICC were 0.89 and 0.93, respectively. In the validation study, the interobserver ICC was 0.85. The median score for patients who united was significantly higher than those who developed a nonunion (11 vs. 7, p < 0.001). A ROC curve demonstrated that a RUSU ≤ 8 had a sensitivity of 88.9% and specificity of 86.1% in identifying patients at risk of nonunion. Patients with a RUSU ≤ 8 (n = 21) were more likely to develop a nonunion (n = 16/21) than those with a RUSU ≥ 9 (n = 2/33; OR 49.6, 95% CI 8.6-284.7). Based on a PPV of 76%, if all patients with a RUSU ≤ 8 underwent fixation at 6 weeks, the number of procedures needed to avoid one nonunion would be 1.3. CONCLUSION: The RUSU shows good interobserver and intraobserver reliability and is effective in identifying patients at risk of nonunion six weeks after fracture. This tool requires external validation but may enhance the management of patients with isolated ulnar shaft fractures.

BACKGROUND: Acute carpal tunnel syndrome (ACTS) is a known complication of distal radius fractures. This study aimed to document the demographics, range of presenting symptoms and risk factors of patients who develop ACTS following a fracture of the distal radius. METHODS: A retrospective review of 1189 patients with an acute distal radius fracture treated in the study centre over a one-year period were identified. Demographic and clinical variables were collected and compared between controls (did not develop ACTS) and those patients who did develop ACTS to identify factors associated with developing ACS. RESULTS: There were 51 (4.3%) distal radius fractures complicated by ACTS. The mean age of patients who developed ACTS was 56 years (range, 16-89) and 73% were female. The median time of onset post-injury was one week (range, 1-12). There was no association between patient background and comorbidities with the development of ACTS. AO-OTA Type C fractures had significantly increased rates of developing ACTS. CONCLUSION: Four percent of distal radius fractures were complicated by ACTS. There was no association between patient background and comorbidities with the development of ACTS. AO-OTA type C complete articular fractures had a significantly higher rate of ACTS. A suggested treatment algorithm for patients presenting with ACTS has been presented. LEVEL OF EVIDENCE: III.

A 26-year-old woman developed acute compartment syndrome (ACS) of her right hand secondary to reperfusion syndrome. She suffered an out-of-hospital cardiac arrest following a pregabalin overdose. Attending paramedics mistakenly gave intra-arterial epinephrine into her right brachial artery. On resolution of her brachial artery spasm, she developed a reperfusion injury to her right hand and subsequently ACS. A four-incision fasciotomy with carpal tunnel decompression was performed and was successful in reversing focal ischaemia and an irreversible functional deficit. This case demonstrates an unusual case of hand ACS secondary to temporary limb ischaemia and reperfusion syndrome following iatrogenic intra-arterial epinephrine administration. We also summarise the current available literature on ACS of the hand including the aetiology, treatment and use of an intracompartmental monitor.

AIMS: The primary aim of this study was to identify independent predictors associated with nonunion and delayed union of tibial diaphyseal fractures treated with intramedullary nailing. The secondary aim was to assess the Radiological Union Scale for Tibial fractures (RUST) score as an early predictor of tibial fracture nonunion. METHODS: A consecutive series of 647 patients who underwent intramedullary nailing for tibial diaphyseal fractures were identified from a trauma database. Demographic data, comorbidities, smoking status, alcohol consumption, use of non-steroidal anti-inflammatory drugs (NSAIDs), and steroid use were documented. Details regarding mechanism of injury, fracture classification, complications, and further surgery were recorded. Nonunion was defined as the requirement for revision surgery to achieve union. Delayed union was defined as a RUST score < 10 at six months postoperatively. RESULTS: There were 41 nonunions (6.3%), of which 13 were infected (31.7%), and 77 delayed unions (11.9%). There were 127 open fractures (19.6%). Adjusting for confounding variables, NSAID use (odds ratio (OR) 3.50; p = 0.042), superficial infection (OR 3.00; p = 0.026), open fractures (OR 5.44; p < 0.001), and high-energy mechanism (OR 2.51; p = 0.040) were independently associated with nonunion. Smoking (OR 1.76; p = 0.034), open fracture (OR 2.82; p = 0.001), and high-energy mechanism (OR 1.81; p = 0.030) were independent predictors associated with delayed union. The RUST score at six-week follow-up was highly predictive of nonunion (sensitivity and specificity of 75%). CONCLUSION: NSAID use, high-energy mechanisms, open fractures, and superficial infection were independently associated with nonunion in patients with tibial diaphyseal fractures treated with intramedullary nailing. The six-week RUST score may be useful in identifying patients at risk of nonunion. Cite this article: Bone Jt Open 2021;2(4):227-235.
RESUMO
INTRODUCTION: Tibial fractures are devastating injuries and a cause of significant morbidity. There is limited information describing the length of time it takes for these injuries to heal. The aim of this study was to define the normal distribution of healing times of a consecutive series of tibial fractures treated with intramedullary (IM) nailing by applying the Radiographic Union Scale for Tibial fractures (RUST). METHODS: 880 radiographs from 217 patients were assessed with RUST. Patients requiring more than one standard deviation from the mean were defined to have a delayed union. RESULTS: 16 patients (7%) developed non-unions and 30 patients (14%) had delayed union. Of the 201 patients who achieved union, the mean time to healing was 18.7 (SD 6.9) weeks, with a wide range from 7 to 52 weeks. In the union group, the rate of healing was greatest in the 8 to 12-week period. In contrast, in the delayed union group there was a lower peak rate of change, which was reached at a later time point. DISCUSSION: Our data indicates that 7% of patients with tibial fractures treated with IM nailing develop non-unions and over 10% of those progressing to union will take longer than 26 weeks. The data on healing rates is important to surgeons and orthopaedic multidisciplinary staff in guiding management. It can also be of help for patients planning their finances and for giving estimates for personal injury claims. LEVEL OF EVIDENCE: IV, Retrospective cohort study.
