Etiology and outcome of 155 patients with midfoot fractures between 1972 and 1997 were analyzed to create a basis for treatment optimization. Cause of injuries were traffic accidents (72.2%), falls (11.6%), blunt injuries (7.7%) and others (5.8%). Isolated midfoot fractures (I) were found in 55 (35.5%) cases, Lisfranc fracture dislocations (L) in 49 (31.2%), Chopart-Lisfranc fracture dislocations (CL) in 26 (16.8%) and Chopart fracture dislocations (C) in 25 (16%). One hundred and forty eight (95%) of the midfoot fractures were treated operatively; 30 with closed reduction, 115 with open reduction, 3 patients had a primary amputation. Seven (5%) patients were treated non-operatively. Ninety seven (63%) patients had follow-up at an average of 9 (1.3-25, median 8.5) years. The average scores of the entire follow-up group were as follows: AOFAS - sum of all four sections (AOFAS-ET): 296, AOFAS-Midfoot (AOFAS-M): 71, Hannover Scoring System (HSS): 65, and Hannover Questionnaire (Q): 63. Regarding age, gender, cause, time from injury to treatment and method of treatment no score differences were noted (t-test: p>0.05). L, C or I showed similar scores and CL significantly lower scores (AOFAS-ET, AOFAS-M, HSS, Q). The highest scores in all groups were achieved in those fractures treated with early open reduction and operative fixation. Midfoot fractures, particularly fracture dislocation injuries, effect the function of the entire foot in the long-term outcome. But even in these complex injuries, an early anatomic (open) reduction and stable (internal) fixation can minimize the percentage of long-term impairment.
Although overall car passenger safety has improved, the relative incidence of foot and ankle fractures has increased. Comparing drivers and front seat passengers, the foot pedals, steering wheel, or the asymmetric design of the dashboard did not influence injury incidence, mechanism, or severity. Foot fractures are mainly caused by the foot compartment deformation in head-on collisions, and therefore improvements in foot compartments are essential for fracture prevention.
We analyzed retrospectively 1191 cases of bone graft harvesting of the iliac crest which had been performed at our hospital between 1982 and 1991. There was an operative revision rate of 2.8%. For further study, we analyzed the clinical reports of all autograft (iliac crest) donors in a representative year (1991) and re-examined all those who still had symptoms. A total of 104 grafts were taken from 97 patients. Of these, 18 developed postoperative complications (19.6%), such as hematoma, which could usually be treated with local procedures such as aspiration. The rate of hematoma tended to be lower in those patients who had received a local coagulant, but this was not significant. Of the patients 55% still had problems 1 year after operation at the time of re-examination, but in most cases they were minor, for example, local irritation or discomfort. Serious problems developed in those patients who had a palpable defect of the iliac crest. We advise using local coagulants to decrease the rate of postoperative complications, although we cannot statistically prove the effect. When large grafts are harvested, the iliac crest should be reconstructed for better long-term results.
Significant progress has been made in terms of the management of calcaneal fractures. This is reflected in the marked decrease in complication rates associated with the current intervention of these potentially devastating injuries. The treatment priorities that, in the authors opinion, are key to achieve best results in a displaced calcaneal fracture are anatomic reconstruction of the entire calcaneus: articular surfaces, height, alignment, and length, with a function directed postoperative management. The value of these priorities are confirmed by the authors longterm follow-up results as presented here. To reemphasize, conservative treatment should be considered only in cases of extraarticular fractures, minor displaced intraarticular fractures in nonambulatory patients, and in cases where there is a clear contraindication for surgery. Regarding the technical requirements for an anatomic reconstruction, the os calcis fracture should be categorized as a procedure for experts. In two-part fractures, according to the Sanders classification, an anatomical reduction is obtainable in more than 80%-90% of cases. However, in consideration of the articular cartilage damage, a 70% rate of good to excellent clinical results seems realistic. In three-part fractures, anatomic reduction is attainable in about 60% of cases with a 70% rate of good results. These two subgroups comprise about 90% of all calcaneus fractures. It is the authors recent experience to optimize the extended lateral approach using posteromedial and anterolateral windows, so that an anatomic reduction in more than 60% of Sanders Type III os calcis fractures can be achieved. Further scientific work in this area of trauma orthopedics would benefit most from a general consensus on a fracture classification system and on a clinical scoring system, with 5 year follow-up studies using these treatment methods and evaluation systems.
