The Impact of COVID-19 on the Choice of Treatment for Hand Fractures: A Single-Centre Concordance Study.

Background: Management of hand trauma has evolved to incorporate assessment, treatment and rehabilitation of patients in a 'one-stop' clinic on initial presentation. Our aim was to evaluate the effect of coronavirus disease 2019 (COVID-19) on the choice of treatment for hand fractures using inter-rater agreement between surgeons. Methods: All patients with hand fractures during the COVID-19 lockdown from March to May 2020 were included in the study. Two experienced hand surgeons blinded to management and outcomes independently reviewed radiographic images and relevant clinical history to provide their opinion on optimal treatment. Weighted kappa analysis was performed to determine concordance and inter-rater agreement between the two surgeons and actual management. Results: The study included 82 patients (62 men and 20 women) with a mean age of 40.3 (SD 19.7). The injuries occurred most often at home following an accident (34%) or a fall (28%). Fractures involved the metacarpals in 29 patients and the distal phalanx in 22 patients. Thirty-five patients underwent surgery, whereas 47 were managed conservatively. Overall agreement between actual management and consultant A and consultant B was moderate (κ = 0.55, p < 0.0001 and κ = 0.63, p < 0.0001, respectively). Subgroup analysis showed a weak agreement between actual management of metacarpal fractures and consultant A and consultant B (κ = 0.22, p = 0.29 and κ = 0.47, p = 0.02, respectively). Inter-rater agreement was substantial for management of metacarpal fractures (κ = 0.73, p < 0.0001), but weak for distal phalanx fractures (κ = 0.29, p = 0.03). Conclusion: Our study has shown that overall management of hand fractures remained optimised throughout the pandemic. However, a lack of concordance was observed in the management of metacarpals. Level of Evidence: Level IV (Therapeutic).

The role of ultrasonography in the assessment of ulnar collateral ligament injury of the thumb - a diagnostic test accuracy meta-analysis.

The accurate diagnosis of ulnar collateral ligament (UCL) injuries of the thumb is important in identifying patients requiring surgery. Stener lesion, the most severe form of such injuries, is debilitating and leads to chronic instability if misdiagnosed. We evaluated the diagnostic accuracy of ultrasonography (USS) in UCL injuries. A systematic review of existing literature was performed with a meta-analysis using a bivariate mixed-effects model to estimate summary sensitivity and specificity. All observational studies were assessed, with participants of any age, who sustained UCL injuries of the thumb. A hierarchical model was used to generate a hierarchical summary receiver operating characteristic (HSROC) curves. We identified 17 studies reporting a total of 593 UCL injuries. Pooled estimates for sensitivity and specificity were 0.96 (95% CI 0.89-0.99) and 0.90 (95% CI 0.81-0.94), respectively for the diagnosis of Stener lesions; 0.81 (95% CI 0.66-0.93) and 0.87 (95% CI 0.67-0.96), respectively for non-displaced complete ruptures and 0.82 (95% CI 0.66-0.92) and 0.94 (95% CI 0.85-0.98), respectively for complete ruptures without Stener lesion. The area under the curve (AUC) for Stener diagnosis using USS was 0.98, suggesting excellent diagnostic accuracy. Our meta-analysis suggests that USS is a reliable and accurate method of diagnosis for UCL injuries. Moreover, it has excellent diagnostic accuracy for Stener lesions and may be used in the diagnostic work-up of UCL injuries with magnetic resonance imaging being reserved for ambiguous cases.

The Impact of Cervical Musculoskeletal Disorders on UK Consultant Plastic Surgeons: Can We Reduce Morbidity With Applied Ergonomics?

BACKGROUND: Based on anecdotal and observational evidence, we hypothesized that the prevalence of cervical musculoskeletal disorder (C-MSD) would be high among plastic surgeons. A questionnaire review was undertaken to test this hypothesis. Ergonomic assessment was undertaken to assess causal factors of C-MSD. METHOD: An anonymous questionnaire recording demographics, physical symptoms and behavioral responses to C-MSD was distributed to UK Plastic Surgery consultants. The postural impact of wearing loupes was assessed using motion capture techniques and recording cervical muscular activity. RESULTS: The questionnaire response rate was 81%. The prevalence of cervical spine morbidity was recorded as 32%. Employment implications included 28% of the cohort requiring sick leave. The professional impact was 7% permanently modifying their practice. There were 2 factors significant for C-MSD, the surgeons' age and the duration in hours of wearing loupes per week. Ergonomic assessment of surgeons operating in loupes demonstrated: 1. increased forward and lateral cervical flexion; 2. increased cervical muscular activity to maintain the protracted "head forward" posture; and 3. prolonged static posturing to maintain head position for visual focus. Table height adjustment and variation of loupe working distance can reduce neck flexion. CONCLUSIONS: Cervical morbidity is a prevalent problem among plastic surgeons. Long procedures, static postures and neck flexion result in the "head forward" posture. This posture exaggerates when operating with loupe magnification. Early-middle-aged consultants are more prone to cervical morbidity hence afflicted when at the top of their game. The work force is diminished for a potentially avoidable morbidity. Rather than accept this morbidity, co-operation between plastic surgeons and ergonomist may help to reduce injury.

The "Swiss-Roll" flap: a modified C-V flap for nipple reconstruction.

Nipple reconstruction is an integral step in breast reconstruction. There are a variety of local-flap based techniques however one of the most commonly used is the C-V flap. The traditional flap forms a nipple shell composed of dermis and epidermis containing a core of subcutaneous fat. The shortcomings of this technique are that it relies on subcutaneous fat for nipple bulk and with time loses a significant part of its volume. We present a modification of the C-V flap designed for use in breasts with little subcutaneous fat in order to minimise post-operative nipple projection loss.
