Techniques for fixation of fractures of the lateral
malleolus have remained essentially unchanged since the 1960s, but
are associated with complication rates of up to 30%. The fibular
nail is an alternative method of fixation requiring a minimal incision
and tissue dissection, and has the potential to reduce the incidence
of complications. We reviewed the results of 105 patients with unstable fractures
of the ankle that were fixed between 2002 and 2010 using the Acumed
fibular nail. The mean age of the patients was 64.8 years (22 to
95), and 80 (76%) had significant systemic medical comorbidities.
Various different configurations of locking screw were assessed
over the study period as experience was gained with the device.
Nailing without the use of locking screws gave satisfactory stability
in only 66% of cases (4 of 6). Initial locking screw constructs
rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable.
Overall, seven patients had loss of fixation of the fracture and
there were five post-operative wound infections related to the distal
fibula. This lead to the development of the current technique with
a screw across the syndesmosis in addition to a distal locking screw.
In 21 patients treated with this technique there have been no significant
complications and only one superficial wound infection. Good fracture
reduction was achieved in all of these patients. The mean physical
component Short-Form 12, Olerud and Molander score, and American Academy
of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean
of six years post-injury were 46 (28 to 61), 65 (35 to 100) and
83 (52 to 99), respectively. There have been no cases of fibular
nonunion. Nailing of the fibula using our current technique gives good
radiological and functional outcomes with minimal complications,
and should be considered in the management of patients with an unstable
ankle fracture.
We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification. Osteosynthesis involved a lateral approach and the use of the AO calcaneal plate. The mean follow-up was for ten years (7 to 15). Clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS), the Creighton-Nebraska Score, the Kerr, Prothero, Atkins Score and the SF-36 Health Questionnaire. The radiological evaluation consisted of lateral and axial views of the os calcis. Arthritic changes in the subtalar joint were assessed with an internal oblique view and were graded using the Morrey and Wiedeman scale. There were 18 excellent (38.3%), 17 good (36.2%), three fair (6.3%) and nine poor (19.2%) results. Five patients had a superficial wound infection and five others eventually had a subtalar arthrodesis because of continuing pain. Restoration of Böhler’s angle was associated with a better outcome. The degree of arthritic change in the subtalar joint did not correlate with the outcome scores or Sanders’ classification. Prompt osteosynthesis should be considered for intra-articular fractures of the calcaneum in order to restore the shape of the hindfoot and Böhler’s angle.
