    Tram system related cycling injuries paper was published this week. I'm not allowed to give the whole paper away free by the publisher, only the abstract.

    Abstract. Introduction
    Understanding of tram-system related cycling injuries (TSRCI) is poor. The aim of this study was to report the spectrum of injuries, demographics and social deprivation status of patients. Secondary aims included assessment of accident circumstances, effects of TSRCI on patients’ confidence cycling, together with time off work and cycling.
    A retrospective review of patients presenting to emergency services across all hospitals in Edinburgh and West Lothian with tram related injuries between May 2009 and April 2016 was undertaken. Medical records and imagining were analysed and patients were contacted by telephone.
    191 cyclists (119 males, 72 females) were identified. 63 patients sustained one or more fractures or dislocations. Upper limb fractures/dislocations occurred in 55, lower limb fractures in 8 and facial fractures in 2. Most patients demonstrated low levels of socioeconomic deprivation. In 142 cases, the wheel was caught in tram-tracks, while in 32 it slid on tracks. The latter occurred more commonly in wet conditions (p = 0.028). 151 patients answered detailed questionnaires. Ninety-eight were commuting. 112 patients intended to cross tramlines and 65 accidents occurred at a junction. Eighty patients reported traffic pressures contributed to their accident. 120 stated that their confidence was affected and 24 did not resume cycling. Female gender (p < 0.001) and presence of a fracture/dislocation (p = 0.012) were independent predictors of negative effects on confidence. Patients sustaining a fracture/dislocation spent more time off work (median 5 days vs 1, p < 0.001) and cycling (median 57 days vs 21, p < 0.001).
    TSRCI occur predominantly in young to middle-aged adults with low levels of socioeconomic deprivation, most commonly when bicycle wheels get caught in tram-tracks. They result in various injuries, frequently affecting the upper limb. Traffic pressures are commonly implicated. Most patients report negative effects on confidence and a sizeable minority do not resume cycling. TSRCI can result in significant loss of working and cycling days.

    Thanks Prof Oliver for your diligence in researching this topic of importance to virtually all cyclists in Edinburgh, and indeed society as a whole.

    Working on the basis that few here will have easy access to the Archives of Orthopaedic and Trauma Surgery, do you have any objections if others provide existing publicly available links to the complete paper?

    Murum, please provide links to other material. Users can email me off forum to ask for copies of the paper. My email is in the post. Chris Oliver

  4. I were right about that saddle

    Very interesting abstract, thanks Chris.

    To add an anecdatum to the thread I was talking to a keen working class cyclist from Craigmillar the other day at Bridgend Farm. To quote him;

    The kids can all go a bike but their folks winnae let them ride into town.

    I've always had the impression that Edinburgh city centre cyclists are predominantly middle class. PoP seems like Waitrose on Wheels sometimes.

    I would love to see Craigmilar coming and going by bicycle but I have no idea if they want to and if so how to bring it about. Other than high-quality segregated paths and houses with suitable storage for bikes built in.

    @IWRATS The road to from Cameron Toll to Craigmillar is hairy enough on a bike but out to the ERI is even worse. I had a relative undergo a reverse-shoulder operation recently due to a fall, and while paying visits to ERI, I was struck by how narrow the cycle lane is at the brow of the hill just NW of the hospital. Double-yellow-lines and then literally about 40cm of cycle lane, and at the precise point you need some support from motorised idiocy. Sigh.

    @Snowy - Indeed. It actually gets even worse if you keep going past the hospital:

    Here, before disappearing at the pinch points here and here (I have had drivers try and overtake me through those)
