Congenital vertical talus: a retrospective and critical review of 32 feet operated on by peritalar reduction.

Thirty-two feet in 23 children treated for congenital vertical talus by peritalar reduction have been evaluated. The age at operation ranged from 9 months to 8 years (mean 3.2 years). The follow-up ranged from 2.8 to 19.1 years (mean 9.2 years). In eight feet Green-Grice extraarticular subtalar arthrodesis was performed as part of a one-stage procedure. Eight of all operated feet required a second surgery 2.2 years after the first operation. In all the reoperated feet the Green-Grice arthrodesis was performed as well. Clinical examination found excellent results in five feet, good results in 12, fair results in nine, and poor results in six feet. The severe type of deformity, other abnormalities, and less extensive surgical procedures contributed to worse clinical results. Poor clinical results were associated with persistent equinus of the hindfoot, abduction of the forefoot, restriction of supination and eversion, and weakness of push-off power. X-ray examination showed excellent results in three feet, good in nine, fair in 13, and poor in seven feet. Poor radiological results were observed in children operated on after the fourth year of age. In most of the feet the navicular remained dislocated dorsally, dorsally and medially, and dorsally and laterally toward the head of the talus. A divergence between a relatively good appearance of the operated foot and a worse radiographic image has been observed. The Green-Grice extraarticular subtalar arthrodesis combined with the peritalar reduction method led to overcorrection in seven feet.

[Isolated talus metastasis of an occult bronchial carcinoma--a rare cause for chronic foot disorders].

A case of a solitary metastatic lesion of the talus from an occult histologically confirmed bronchogenic carcinoma is reported. Clinical, radiologic, histological, and laboratory manifestations are described. Four months after complete resection of the talus and consecutive internal and external fixation of the ankle joint a below-knee amputation was done because of progressive infiltration. A review is given on reports in the literature of rare cases of solitary metastatic deposits of malignant tumors below knee and elbow. This unusual cause of foot pain should be taken into account concerning differential diagnosis in elderly patients. A mistake for a septic osteolysis is possible.

[Sagittal burst fracture of the talus].

Fractures of the talus have a relatively low incidence, accounting for 0.3% of all bone fractures and 3.4% of fractures of bones in the foot. These injuries affect the neck of the talus more frequently than its head or body. Because of the combined traumatic mechanism, sagittal fracture of the talar body is extremely rare; the literature contains only a few case reports, all with severe dislocation of the fragments. Plain film radiographs and CT pictures recorded in a rare case of nondisplaced fracture of the talar body are presented.

Giant cell tumor of the talus with secondary aneurysmal bone cyst.

Giant cell tumors of the talus are very uncommon. Secondary aneurysmal bone cyst changes are well documented in the literature with giant cell tumors being one of the most common underlying lesions. However, no previous case of this combination has been documented in the podiatric literature. The diagnosis of these lesions can be very challenging since they share many common features. Although previous reports describe a higher recurrence rate of giant cell tumors when found in the small bones of the hands and feet, reported cases of this entity in the talus indicate a less aggressive natural history with rare malignant transformation. A case report and review of the literature are presented.

[Talus substitution using a vascular pedicled bone flap].

Authors report on the substitution of in consequence of complete talus luxation, missing talus. It succeeded with the transplantation of a free vascular pedicled bone block, gained from the crista ilei to retain the length of the extremity and to secure the gait of the patient without aid, finally to make the return to the former active life possible. The use of the method in similar cases was found to be unknown after a review of the literature. This case is an example demonstrating the growing significance of microsurgery in the traumatology.

Avascular necrosis of the talus treated by core decompression.

We reviewed 11 patients (17 ankles) who had had core decompression for symptomatic avascular necrosis of the talus before collapse. The Mazur grading system was used to assess function preoperatively and at final follow-up, and radiographs were graded according to the Ficat and Arlet (1980) classification modified for the ankle. At a mean follow-up of seven years (2 to 14) 14 ankles (82%) had an excellent or good outcome (Mazur scores > 80 points; pain scores > 40 points (41 to 50). The other three ankles required tibiotalar fusion at a mean of 13 months (5 to 20) after core decompression. We conclude that core decompression is a viable method of treatment for symptomatic avascular necrosis of the talus before collapse.

Fracture-dislocation of the neck of the talus in a ten-year-old child: a case report and review of the literature.

A ten-year-old female underwent open reduction and internal fixation of a Hawkins type III fracture of the talar neck. The fracture united within three months. However, avascular necrosis of the body of the talus occurred. Partial collapse of the talar body ensued despite protection from weight-bearing for eight months after surgery. This case illustrates that fracture-dislocation of the talus can occur in a child and has a guarded prognosis.

Single-stage surgical correction of congenital vertical talus.

Forty-one patients (55 feet) with congenital vertical talus (CVT) were reviewed. Thirty of the feet were associated with neural tube defects, 10 with neuromuscular disorders, five with congenital malformation syndromes, and none with chromosomal aberrations. Ten of the feet were idiopathic. All were treated with a single-stage surgical correction as described, by using the Cincinnati incision, and performed by the same surgeon. Thirty-two patients (42 feet) were available for clinical and radiographic follow-up averaging 7 years (range, 2-12) from the time of surgery. There were no wound complications or avascular necrosis of the talus. In 10 feet, subsequent reoperation was necessary. At final follow-up, results were based on the clinical and radiographic outcomes and included 31 good and 11 fair. All patients and families were satisfied with the results and appearance of the feet. There were no bony prominences or skin problems. The presence of mild pain was noted in only three feet. Radiographically, there was a significant improvement in the anteroposterior (AP) and lateral talocalcaneal and talo-first metatarsal angles, and at follow-up, the group averages for each of these angles were within the normal range. In treating CVT, good clinical and radiographic results can be obtained with a low incidence of complications using this single-stage surgical correction of the hindfoot and midfoot deformities.

Early surgical treatment for congenital vertical talus.

Congenital vertical talus is characterised by a dislocated talonavicular joint in association with an equinus position of the calcaneus. We report the results in 13 operated feet in 10 children, 3 of whom (5 feet) presented with a primary neurological disorder and 2 of whom (3 feet) suffered from arthrogryposis multiplex congenita. The other children were normal. All patients were surgically treated by a one-stage procedure which included reduction of the talonavicular joint and correction of the hindfoot equinus, trying to avoid tendon lengthenings and transfers. The age at operation was between the 3rd and the 6th month of life, with one child being operated on later due to other reasons. The patients were reviewed after an average time of 3.5 +/- 2.2 years. The clinical results were good or excellent in ten feet. Two feet showed partial or complete recurrence and one foot was slightly over-corrected. Radiographic angle measurements (talo-metatarsal I angle and talocalcaneal angle on the anteroposterior radiograph; talocalcaneal, tibiotalar and tibiocalcaneal angles on the lateral radiograph) returned to normal values in the ten good or excellent feet. Early operative treatment for congenital pes vertical talus leads to very satisfactory functional and cosmetic results, usually avoiding extensive procedures including tendon lengthenings and tendon transfers.

The anterior approach for the treatment of posterior osteochondral lesions of the talus: comparison of different surgical techniques.

INTRODUCTION: Most of all osteochondral talar lesions are located in the middle and posterior area of the talar surface. Malleolar osteotomy is often used to access the defect but may be associated with malunion or secondary osteoarthritis. We present an alternative approach to the talus with temporary removal and replacement of a tibial bone block and compare it with other anterior approaches described in the literature. PATIENTS AND METHODS: Thirteen patients (5 males, 8 females) with an average age of 27.2 years and an osteochondral talar lesion were included in our study. All patients were previously operated on the same ankle. Ten lesions were caused by a sports injury. The average follow up was 45 months. The patients were evaluated before and after surgery using the ankle and hindfood score (AOFAS). For the analyses baseline clinical data were compared with follow up data using the Wilcoxon test. RESULTS: The overall improvement between the preoperative and postoperative AOFAS scores was an average of 34.9 points (P=0.0002). No complications occurred at the site of the tibial bone block and the donor site at the talus. There were no patients with recurrence or an ankle osteoarthrosis in the follow up period. CONCLUSION: The removal of a tibial bone block and its subsequent replacement is a useful technique to access osteochondral talar lesions for osteochondral transplantation for which arthroscopic interventions have failed. The results are comparable to other anterior approaches described in the literature.

Solitary myeloma of the talus bone.

Solitary myeloma can present as either extramedullary plasmacytoma or solitary plasmacytoma of bone (SPB). More than half of reported cases of SPB are localized to the spine. The rest include appendage long bones of the skeleton, pelvis, and skull. The first case of SPB (to the authors' knowledge) is reported involving the talus bone of the foot. Although approximately 50% of SPB patients progress to multiple myeloma in the first 3 years after diagnosis, aggressive local therapy is indicated because the median survival of patients with SPB is better than that for multiple myeloma.

Bone density of the human talus does not increase with the cartilage degeneration score.

Osteoarthritis (OA) is a common, disabling condition of synovial joints that can eventually lead to reduced, or lost, mobility. It is characterized by both articular cartilage degeneration and subchondral bone changes. However, a cause-and-effect relationship between the two tissues remains controversial. Increased subchondral bone density has been associated with early degenerative changes in the cartilage of knee, hip, and finger joints-joints in which progressive changes to OA are common. In contrast, the ankle joint is known to exhibit early cartilage changes, but is not prone to the development of OA. In the present study, it was found that cartilage degeneration on the talus is not associated with an increase in bone density, as assessed through peripheral quantitative computed tomography (pQCT).

Anatomical consideration of vascularized bone graft transfer from the medial calcaneus to the talus.

To investigate the possibility of use of the calcaneal branches of the posterior tibial artery as the pedicle for the vascularized bone graft to the talus, a detailed anatomical study was carried out on 30 fresh cadaver feet. Although there are several branches from the posterior tibial artery to the calcaneus, the largest posterior branch was defined as the main calcaneal branch. We recognized frequently a large branch nourishing the superior part of the calcaneus and named it the superior calcaneal branch. Twenty feet had the superior calcaneal branches. Pedicled bone grafts using the superior calcaneal branch to the postero-medial portion of the talar body were possible in 18 of 20 feet. Pedicled bone grafts using the main calcaneal branches were possible in 9 of 12 feet in which the superior calcaneal branches were not available. Finally, vascularized bone grafts were judged to be feasible in 27 feet (90%).

Bilateral osteonecrosis of the talus and "standing obsession" in a patient with anorexia nervosa.

METHOD: We report a case of a 24-year-old woman with anorexia nervosa (AN), obsessive-compulsive disorder (OCD), and osteoporosis. During 8 years of illness, her body mass index (BMI) fluctuated between 10 and 13,5 kg/m(2). She developed hyperactivity and the habit to stand for all daily activities. She did not allow herself to sit at any time, she had "standing obsession." A few weeks after her admission to an inpatient unit for eating disorders, she reported pain in both ankles. Results and Discussion The rheumatological diagnosis was bilateral osteonecrosis of the talus and generalized osteoporosis. The latter and excessive biomechanical stress could be interpreted as the cause for this serious and irreversible bone destruction. The following case shows how the psychiatric comorbidity of a patient suffering from an eating disorder with a chronic course can lead to severe somatic complications.

HOXD10 M319K mutation in a family with isolated congenital vertical talus.

Congenital vertical talus (CVT) is a primary dislocation of the talonavicular joint that often occurs in neuromusculoskeletal syndromes, but may also be seen as an isolated abnormality. Six families with isolated CVT were ascertained. DNA was isolated from 21 affected individuals and 17 unaffected individuals from these families, as well as from five sporadic patients with CVT. Variable expressivity was noted in three families, manifesting as clubfoot in three individuals. Genome-wide linkage analysis generated a maximum two-point logarithm of odds score on chromosome 2q with D2S1353 (Zmax = 1.43 at theta(max) = 0.1), 17 Mb from the HOXD gene cluster. DNA from one affected individual of each family was subjected to mutational analysis of the HOXD10 gene. A single missense mutation was identified (M319K, 956T > A) in the homeodomain recognition helix of the HOXD10 gene that segregated with disease in one large British family. This mutation was recently described in a family of Italian descent with CVT and Charcot-Marie-Tooth deformity HOXD10 gene mutations were not identified in any of the other families or sporadic patients with CVT, suggesting that genetic heterogeneity underlies this disorder.

Malignant histiocytoma in talus: diagnostic problems.

A malignant histiocytoma of the left talus is described. The patient was introduced to our hospital because of an infected recidivation of a partly exstirpated tumor. It is classified as a metastasis of a malignant melanoma. The final histologic diagnosis could be proved by the original slides. The exarticulation of the knee was followed by chemotherapy.

[Phlebography in fractures and dislocations of the talus (author's transl)].

Late osteonecrosis and/or osteoarthrosis occurs frequently after dislocation and fracture dislocation of the talus. The cause seems to be a primary vascular lesion additionally to the initial damage of bone and cartilage and subsequent joint incognity. We recommended phlebography 3 to 6 months after injury for the proof or exclusion of a vascular lesion. Our experience with this method has been encouraging.
