The incidence of congenital pseudarthrosis of the clavicle and review of the literature.

The aim of this study was to identify the hitherto unknown incidence of congenital pseudarthrosis of the clavicle (CPC), based on a cohort of continuous livebirths born in our hospital, to review the literature and investigate if there is evidence supporting the published association between left-sided CPC and dextrocardia. From our electronic medical record and radiology databases, we identified all live births and patients with the diagnosis of CPC born from 2000 to 2016. We reviewed the imaging which included one or both clavicles to search for unrecorded CPC cases and reviewed all retrievable CPC publications listed in PubMed and publications quoted within these publications going back to 1910. We identified 87 407 livebirths of which 41 800 had radiological studies done, 14 885 showing one or both clavicles. We found five cases of CPC, two from the electronic database and three from our imaging review, giving an incidence of 1 of 17 481 livebirths. We identified 138 publications reporting paediatric and adult CPC cases and 12 review articles, including 429 patients (187 female; 159 male; 83 unknown) with 456 CPCs and a minimum of 24 additional patients from case reports for which we could not retrieve details. Two publications reported one case of left-sided CPC with dextrocardia, either not showing left/right marking or only showing the CPC with the aortic knob on the same side. We report the first CPC incidence of 0.0057%, provide the by far most inclusive CPC epidemiology based on 429 patients and could not find reliable proof that there has ever been a patient with left-sided CPC which was associated with dextrocardia.

Mobility after intertrochanteric hip fracture fixation with either a sliding hip screw or a cephalomedullary nail: Sub group analysis of a randomised trial of 1000 patients.

AIMS: The aim of this study was to determine if different patient groups have superior mobility regain following intertrochanteric hip fracture fixation with a cephomedullary nail compared to a sliding hip screw (SHS). PATIENTS AND METHODS: The present study is a subgroup analysis of patients which were enrolled into a randomized controlled trial which randomized 1000 patients with an intertrochanteric hip fracture to fixation with either a short cephomedullary nail (Targon® PF or PFT) or a SHS. In the present study the two treatment groups were dicotomised on the basis of six variables determined at the time of admission; age (<80; ≥80 years), sex, residence (admitted from own home; institutional care), mobility (mobility score ≥7 [good]; <7 [poor]), mental status (AMTS < 7 [cognitively impaired]; ≥7) and health status (ASA < 3; ≥3). The primary outcome measure was the difference between mobility score pre-fracture and mobility score during the year after hip fracture fixation. RESULTS: Patients less than 80 years of age, those admitted from their own home, cognitively intact patients and patients who mobilised without assistance pre-fracture, recovered superior mobility when fracture fixation was performed with a nail compared to a SHS. Those patients admitted from institutional care, those with significant cognitive or mobility impairment at the time of the injury did not have any significantly improved benefit in mobility regain with a nail compared to a SHS. CONCLUSION: Fixation of an intertrochanteric hip fracture with a cephomedullary nail results in superior recovery of mobility for younger patients who prior to the injury were more mobile, cognitively intact and living at home.

The use of weekly departmental review of all orthopaedic intra-operative radiographs in order to improve quality, due to standardized peer expectations and the "Hawthorne effect".

INTRODUCTION: Clinical governance highlights risk management, clinical effectiveness and use of evidence based practice as key elements in the provision of a quality service. A change in the method of quality control in our orthopaedic trauma unit allowed us the opportunity to study if the quality of operative outcomes had changed as a result. The Hawthorne effect refers to phenomenon whereby employees work quality improves by virtue of their awareness that their labour is being assessed. METHODS: A new outcome appraisal forum was introduced in our department in 2009. This forum involved a weekly whole department review of all the previous week's intraoperative radiographs. We used the tip apex distance (TAD) of the dynamic hip screw (DHS) procedures in hip fracture patients as a surrogate marker, of any objective change in the quality and consistency of intra-operative radiographs, in the year prior to and after the introduction of this review system. RESULTS: We found that the mean TAD and the number of TAD measurements over 25 mm decreased significantly in the year after the new quality control mechanism was introduced. CONCLUSION: We would recommend the use of a weekly quality control meeting scrutinizing every intraoperative radiograph as a simple, cost effective method of incorporating many aspects of clinical governance, as well as fostering a culture of quality.

Illness representations in patients with hand injury.

PURPOSE: Differences in illness perception about hand injury may partly explain the variation in health behaviours such as adherence to post-operative therapy, coping strategy, emotional response and eventual clinical outcome. This study examined the illness perception of patients with hand injuries in the acute trauma setting. METHODS: The disability and severity of injury were assessed using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and the Hand Injury Severity Score (HISS). The revised Illness Perception Questionnaire (IPQ-R) was used to explore patients' illness beliefs and perception on hand injury. RESULTS: Fifty seven patients were recruited over the 2 month period. The IPQ-R showed good internal reliability (Cronbach's alpha, 0.68-0.86). There was no correlation between the DASH or HISS scores and the various components of the IPQ-R scores, suggesting that illness perceptions were not influenced by the recent trauma experience. Patients with dominant hand injuries and females reported significantly higher subjective disability. Younger patients believed their injury would last for a limited duration but reported a significantly higher number of related symptoms. Overall, the cohort was optimistic about their treatment and duration of recovery (high treatment control score and low time line score). Beliefs of negative consequences, chronic/cyclical duration and low illness coherence were linked with negative emotional response. High illness identity was associated with perception of pessimistic outcome (high consequences score) and negative emotional response. CONCLUSIONS: The lack of correlations suggests that illness perceptions of patients do not necessarily relate to the recent trauma experience or the severity of their hand injury. Patients in this cohort were optimistic about treatment and their recovery. There was some evidence to suggest that patients with severe injury were over-optimistic about recovery. These findings suggest that there could be a role for psychological intervention in hand injury.
