Does a delay in surgery for distal radial fractures affect patient outcome?

J Hand Surg Eur Vol 2021 Jan 26;46(1):69-74. Epub 2020 Jul 26.

Musgrove Park Hospital, Taunton, UK.

Current guidelines from the British Orthopaedic Association state that if fractures of the distal radius are operated on then this should take place within 3 days of injury for intra-articular fractures, 7 days for extra-articular fractures and 3 days when a trial of conservative management has failed. This retrospective cohort study aimed to assess whether there was any difference in outcome between patients receiving timely or delayed surgery, using the Patient-Rated Wrist Evaluation score at >12 months after injury as the primary outcome measure. Data from 380 patients treated at two district general hospitals over a 5-year period were obtained using electronic databases to capture the demographics and treatment details and postal questionnaires to assess current function. The study showed no statistical or clinical differences in outcome measures between the timely or delayed cohorts in any of the three treatment groups. III.

Proximal Humerus Fractures: Reliability of Neer Versus AO Classification on Plain Radiographs and Computed Tomography.

Cureus 2020 Jun 9;12(6):e8520. Epub 2020 Jun 9.

Orthopaedics, The Royal Infirmary of Edinburgh, Edinburgh, GBR.

Introduction: Several classifications for proximal humeral fractures exist, with excellent reliability and reproducibility of such classifications being a desirable feature. Despite their widespread use, these systems are variable in both reliability and accuracy. We aimed to, a) assess and compare the reliability of the Neer (complete and abbreviated versions) and Arbeitsgemeinschaft für Osteosynthesefragenbeing (AO) classifications, and b) identify if computed tomography (CT) made any difference to the reliability of Neer and AO classifications when compared to plain radiographs alone.  Materials and methods: This is a single-centre retrospective study identifying all proximal humeral fractures presenting between February 2016 and February 2017 as a result of trauma that subsequently proceeded to CT. Two specialty orthopaedic trainees analysed the plain radiographs as well as CT images over two rounds, spaced two weeks apart. The Neer 16-grade, abbreviated Neer 6-grade and AO classifications were used. Intra- and inter-observer reliability of each classification system was assessed using the Kappa coefficient.  Results: Twenty-two patients were included. The mean age was 62 years (SD 14.5). Management changed in 9/22 patients based on CT. Computed tomography changed Neer-16 type in 16% observations, Neer-6 in 10%, and AO in 23%. This was significant when comparing Neer-6 and AO classifications (p = 0.04). Neer-6 had the best inter-observer reliability (0.737) with the management of one patient changing after CT. On X-ray and CT, intra-observer agreement was substantial, >0.7, using Neer-16 and Neer-6 (p<0.005). Inter-observer agreement for Neer-16 and Neer-6 was substantial, >0.7 (p<0.005). In comparison, intra- and inter-observer agreements for AO were lower on X-ray and CT, 0.4-0.6, (p<0.005).

Conclusion: Our study shows that simplicity is key with a high degree of reliability in the abbreviated Neer classification. Computed tomography allowed greater reliability than radiographs in classifying fractures, affecting management decisions in 41% of patients. The comprehensive Neer classification showed similar intra- and inter-observer reliabilities to AO.

Headless compression screw fixation prevents symptomatic metalwork in arthroscopic ankle arthrodesis.

Foot Ankle Surg 2012 Jun 8;18(2):111-3. Epub 2011 May 8.

Trauma and Orthopaedic Directorate, University Hospitals Bristol NHS Foundation Trust, Marlborough Street, Bristol BS2 8HW, United Kingdom.

Background: Arthroscopic ankle arthrodesis (AAA) is a recognised salvage procedure for end-stage arthritis. Its reported disadvantages include a high rate of re-operation for symptomatic prominence of metalwork. We propose that the use of a headless screw would reduce this re-operation rate.

Methods: We reviewed 32 AAAs, using the Acutrak™6/7 mm headless screw fixation system, to determine peri-operative parameters and complication rates.

Results: At an average of 22 months follow-up, 28 (88%) had united radiologically. There were 2 stable fibrous non-unions not requiring further intervention. Of the other 2, one was successfully revised using an open technique, and the other patient died of unrelated causes. There were no other complications in this series, with no cases of metalwork removal for prominence or pain.

Conclusions: Using a headless screw fixation for arthroscopic ankle arthrodesis prevents symptomatic metalwork prominence and the requirement for removal.
