Patients undergoing femoral lengthening by external fixation
tolerate treatment less well when compared to tibial lengthening.
Lengthening of the femur with an intramedullary device may have
advantages. We reviewed all cases of simple femoral lengthening performed
at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities,
congenital limb deficiencies and lengthening with an unstable hip
were excluded, leaving 33 cases (in 22 patients; 11 patients had
bilateral procedures) for review. Healing index, implant tolerance
and complications were compared.Aims
Patients and Methods
Although patients with a history of venous thromboembolism
(VTE) who undergo lower limb joint replacement are thought to be
at high risk of further VTE, the actual rate of recurrence has not
been reported. The purpose of this study was to identify the recurrence rate
of VTE in patients who had undergone lower limb joint replacement,
and to compare it with that of patients who had undergone a joint
replacement without a history of VTE. From a pool of 6646 arthroplasty procedures (3344 TKR, 2907 THR,
243 revision THR, 152 revision TKR) in 5967 patients (68% female,
mean age 67.7; 21 to 96) carried out between 2009 and 2011, we retrospectively
identified 118 consecutive treatment episodes in 106 patients (65%
female, mean age 70; 51 to 88,) who had suffered a previous VTE.
Despite mechanical prophylaxis and anticoagulation with warfarin,
we had four recurrences by three months (3.4% of 118) and six by
one year (5.1% of 118). In comparison, in all our other joint replacements
the rate of VTE was 0.54% (35/6528). The relative risk of a VTE by 90 days in patients who had undergone
a joint replacement with a history of VTE compared with those with
a joint replacement and no history of VTE was 6.3 (95% confidence
interval, 2.3 to 17.5). There were five complications in the previous
VTE group related to bleeding or over-anticoagulation. Cite this article:
