[Fractures of the calcaneus. The indications for surgical treatment].

The authors report the results obtained from a study of 41 cases of calcaneal fractures. Surgical treatment, when possible, is to be applied because it allows a satisfactory reconstruction of the subtalar and calcaneocuboid joint. The choice of various surgical methods is facilitated by computerised tomography which allows a precise assessment of the calcaneum. The quality and the stability of the reduction determine in a significant way the functional result.

[Radio-anatomical study of the calcaneus. Accuracy of Böhler's angle measurement].

The authors have studied variations of Böhler's angle by various radiographic incidences. They have defined anatomic references of this angle on the correspondent dry bone. With the same radiographic incidences, Böhler's angle was 32 degrees. This value remained constant when X-ray incidences were modified with 15 degrees in all the directions from the external profile. Anatomic variations of the 3 references on dry bone which define this angle, were very small. Böhler's angle is therefore a good morphologic reference for evolutive study of each patient. It's variation in population needs comparative radiographic control of the opposite side.

[Conservative and semiconservative treatment of calcaneus fractures].

The functional closed and percutaneous techniques for the treatment of fractures of the os calcis are described. We compare the different classifications, reduction techniques, advantages and disadvantages, as well as the results, after open reduction and internal fixation in an attempt to determine the special indications.

[The surgical treatment of calcaneus fractures].

The treatment of intra-articular fractures of os calcis has so far been controversial. For reconstruction of static and dynamic conditions of the foot, complex deformities must be corrected. Besides intra-articular malformation of the talocalcaneal joint that is supposed to lead to posttraumatic arthritis, there are malalignments like lateral displacement, widening and shortening of the heel, depression of talocalcaneal angles and deviation of talocalcaneal or talocuboidal axes. Even if perfect reconstruction of the talocalcaneal joint is not attained, reconstruction of form will provide a better chance for later function. ORIF is therefore superior to conservative techniques. For indication and planning of the procedure fracture analysis including CT is necessary. A lateral approach allows reconstruction and plate fixation of all intra-articular fracture types. For repositioning, temporary lateral external distraction by external fixation is recommended. The operative technique and results are discussed.

[Thalamic fractures of the calcaneus. The authors' experience].

The authors refer their experience in management of thalamic fractures of the heel. Their series includes 22 patients with 24 fractures and comprises the 12-year period 1975-87. They assess the results based on radiological, clinical, functional and occupational criteria, emphasizing the role of the posterior subtalar joint, which imposes an anatomical reconstruction on the orthopaedist, since the final results are conditioned by its arthritic degeneration. Complex fractures with important displacement need surgical treatment with reduction and synthesis. In simple fractures with or without slight displacement, conservative treatment using cast immobilization is now the treatment of choice.

[Fatigue fracture of the calcaneus].

Formerly, stress-fractures of the metatarsus were the most common stress fractures. But over the last years, tibial and calcaneal localizations have dominated. The diagnosis of a calcaneal stress fracture is usually easy, provided the possibility is remembered. The symptoms are indeed vague, and radiological alterations are often not seen during the first 2 months. Sclerosis (callus formation) is the first finding on roentgenograms. A periosteal reaction like on tabular bone is never seen. Signs of a stress fracture are first seen on bone-scan, but other nonstress-related bone abnormalities which have not manifested any radiographic changes such as early osteomyelitis, fibrous dysplasia, bone tumor, etc. have to be excluded. The treatment is simple. Vigorous activities are stopped for 6 weeks, soft heel pads are given, partial weight-bearing can be helpful for some days. Plaster is usually neither necessary nor useful.

[Thalamic fractures of the calcaneus. Value of computed x-ray tomography in therapeutic decisions].

The authors have studied 35 fractures of the calcaneal thalamus and compared the information provided by plain radiology and CT scans of the calcaneal tuberosity, especially those connected with the condition of the posterior subtalar joint. In 8 cases out of 35, the study of the CT sections yielded information that allowed changing the indications for treatment. The authors emphasize the quality of the data obtained, which makes it possible to justify a functional treatment or to establish a preoperative schedule.

[Osteochondritis dissecans of the calcaneus].

We report a case of osteochondritis dissecans located to the posterior calcanear articular surface of the talocalcaneal joint. The lesion was diagnosed by radiological tomography of the joint. The treatment was surgical excision of the affected segment. The patient was still symptomfree three years later.

[Osteosynthesis of thalamic fractures of the calcaneus using triangulation-fixed 1/4-tube plates. Preliminary results of 32 osteosyntheses].

The authors present a new type of osteosynthesis fixture used in calcaneal thalamus fracture repair. This consists in triangulation fixation, the upper- and retromost part of the thalamus being the apex of the triangle. This is performed using 2 or 3 1/4-tube A.O. instrumentation plates, with adaptable positioning according to the type of fracture. This system presents two advantages compared to currently used fixation components: it is less bulky and is associated with a reduced risk of skin-related complications. Calcaneal reconstruction is much more stable because the plates are in alignment with talocalcaneal stress lines, on the one hand, and because they form a truss that counteracts secondary displacement of the reconstructed thalamus. 32 calcaneal syntheses were thus performed during the period between July 1983 and July 1988. These included 8 stage III DUPARC fracture cases (25%), 21 stage IV cases (65.6%), and 3 stage V cases (9.4%). Nine 2-plate fixtures were assembled in an circumflex-like manner and 23 operations involved setting up the fixation components in a "closed triangle". Cuboid anchorage was necessary in 11 cases. Uncomplicated cutaneous necrosis occurred only once in this series (i.e., 3.2%). The stability of this operative procedure was assessed by measurements of Boehler's angle in the immediate postoperative period and after consolidation. The fixation was perfectly stable in 94% of cases (angle loss less than or equal to 5 degrees). Secondary angle loss occurred in 6% of cases (i.e., 2 cases, 8 degrees and 12 degrees respectively), one of which was caused by untimely weight-bearing. Moreover, no case of plate disruption was reported in this series.

[Treatment of intra-articular calcaneus fracture in the standard care hospital].

A total of 49 intra-articular fractures of the calcaneum were treated from January 1985 to December 1988. In 27 cases the fracture was treated with functional therapy, while in 21 cases management was surgical. The diagnostic procedure was the following: conventional radiography was lateral, axial and dorsoplantar exposures after Böhler. These radiographs allow adequate classification and selection for surgery for the treatment of intra-articular fractures. CT examination is often not available in a general or county hospital, and is not essential for the decision as to whether a conservative or a surgical procedure is more appropriate. Intra-articular fracture of the calcaneum is an indication for surgery except when the bones are totally fractured. We excluded from surgery: 6 patients older than 65 years, 3 with multiple trauma, 2 patients who were receiving coumarin treatment, 3 patients with occlusive arterial disease, and 1 patient who had suffered a cerebral stroke. In 4 cases the patients declined the proposed surgical treatment. Surgery was performed 8 days after trauma. Only lateral incisions were used. We used the Bézes technique, in which bone plate and screw fixation is combined with spongiosa grafting. We observed no necrosis of skin or soft tissue and no infection. Follow-up examination was possible in 33 patients (59% after conservative and 81% after surgical treatment). The patients who had undergone surgery had better results as measured by ability to work, gait pattern and radiological findings of arthrosis.(ABSTRACT TRUNCATED AT 250 WORDS)

[Value of functional treatment of severe calcaneus fractures].

Preservation of the gliding joint and muscular strength, avoidance of contracture, and improvement of gait pattern are the major objectives in treatment of patients for severe calcaneal fracture. Follow-up checks were applied to 170 patients, with particular reference being made to the value of functional therapy. Unobstructed mobility of the talocrural joint was recorded from 90 percent of them. Occupational fitness was reduced in 25 percent of the above cases.
