Pin-site infection remains a significant problem for patients treated by external fixation. A randomized trial was undertaken to compare the weekly use of alcoholic chlorhexidine (CHX) for pin-site care with an emollient skin preparation in patients with a tibial fracture treated with a circular frame. Patients were randomized to use either 0.5% CHX or Dermol (DML) 500 emollient pin-site care. A skin biopsy was taken from the tibia during surgery to measure the dermal and epidermal thickness and capillary, macrophage, and T-cell counts per high-powered field. The pH and hydration of the skin were measured preoperatively, at follow-up, and if pin-site infection occurred. Pin-site infection was defined using a validated clinical system.Aims
Methods
Both conservative and operative forms of treatment
have been recommended for patients with a ‘floating shoulder’. We
compared the results of conservative and operative treatment in
25 patients with this injury and investigated the use of the glenopolar
angle (GPA) as an indicator of the functional outcome. A total of
13 patients (ten male and three female; mean age 32.5 years (24.7
to 40.4)) were treated conservatively and 12 patients (ten male
and two female; mean age 33.67 years (24.6 to 42.7)) were treated
operatively by fixation of the clavicular fracture alone. Outcome
was assessed using the Herscovici score, which was also related
to changes in the GPA at one year post-operatively. The mean Herscovici score was significantly better three months
and two years after the injury in the operative group (p <
0.001
and p = 0.003, respectively). There was a negative correlation between
the change in GPA and the Herscovici score at two years follow-up
in both the conservative and operative groups, but neither were
statistically significant
(r = -0.295 and r = -0.19, respectively). There was a significant
difference between the pre- and post-operative GPA in the operative
group (p = 0.017). When compared with conservative treatment, fixation of the clavicle
alone gives better results in the treatment of patients with a floating
shoulder. The GPA changes significantly with fixation of clavicle
alone but there is no significant correlation between the pre-injury
GPA and the final clinical outcome in these patients. Cite this article:
