We carried out a systematic review of the literature
to evaluate the evidence regarding the clinical results of the Ilizarov
method in the treatment of long bone defects of the lower limbs. Only 37 reports (three non-randomised comparative studies, one
prospective study and 33 case-series) met our inclusion criteria.
Although several studies were unsatisfactory in terms of statistical
heterogeneity, our analysis appears to show that the Ilizarov method
of distraction osteogenesis significantly reduced the risk of deep
infection in infected osseous lesions (risk ratio 0.14 (95% confidence
interval (CI) 0.10 to 0.20), p <
0.001). However, there was a
rate of re-fracture of 5% (95% CI 3 to 7), with a rate of neurovascular
complications of 2.2% (95% CI 0.3 to 4) and an amputation rate of
2.9% (95% CI 1.4 to 4.4).The data was generally not statistically
heterogeneous. Where tibial defects were >
8 cm, the risk of re-fracture
increased (odds ratio 3.7 (95% CI 1.1 to 12.5), p = 0.036). The technique is demanding for patients, illustrated by the voluntary
amputation rate of 1.6% (95% CI 0 to 3.1), which underlines the
need for careful patient selection. Cite this article:
Incomplete avulsion of the proximal hamstrings
can be a severely debilitating injury that causes weakness, pain
while sitting and inability to run. The results of the surgical treatment
of 23 consecutive patients with such injuries at least two years
after surgery are described. The surgery consisted of the repair
of the hamstrings directly onto the ischial tuberosity. At review,
using a visual analogue scale (VAS, 0 to 100), pain while sitting improved
from a mean of 40 (0 to 100) to 64 (0 to 100) (p = 0.024), weakness
from a mean of 39 (0 to 90) to 76 (7 to 100) (p = 0.0001) and the
ability to run from a mean of 24 (0 to 88) to 64 (0 to 95) (p =
0.0001). According to a VAS, satisfaction was rated at a mean of
81 (0 to 100) and 20 patients (87%) would have the same procedure
again. Hamstring strength measured pre- and post-operatively had
improved significantly from a mean of 64% (0% to 95%) to 88% (50%
to 114%) compared with the normal side. Most of these patients with symptomatic incomplete hamstring
avulsions unresponsive to conservative treatment had an improved
outcome after surgical repair.
The treatment of osteochondral lesions of the talus has evolved with the development of improved imaging and arthroscopic techniques. However, the outcome of treatment for large cystic type-V lesions is poor, using conventional grafting, debridement or microfracture techniques. This retrospective study examined the outcomes of 50 patients with a cystic talar defect who were treated with arthroscopically harvested, cored osteochondral graft taken from the ipsilateral knee. Of the 50 patients, 45 (90%) had a mean good to excellent score of 80.3 (52 to 90) in the Karlsson-Peterson Ankle Score, at a mean follow-up of 36 months (24 to 83). A malleolar osteotomy for exposure was needed in 26 patients and there were no malleolar mal- or nonunions. One patient had symptoms at the donor site three months after surgery; these resolved after arthroscopic release of scar tissue. This technique is demanding with or without a malleolar osteotomy, but if properly performed has a high likelihood of success.
