[Pseudarthrosis of the femur neck and ununited ipsilateral diaphyseal fracture. Value of an adjustable 2-piece nail plate].

The authors have treated four patients presenting in the same limb a pseudarthrosis of the neck of the femur and an ununited fracture of the femoral shaft. All the cases were treated by fixation of the diaphyseal lesion and valgus osteotomy of the femoral neck. To achieve this, the authors recommend the use of a two-piece nail plate sufficiently long to bridge the lower fracture site. In all the cases, union occurred without necrosis of the femoral head.

Congenital pseudarthrosis of long bones: a clinical, radiographic, histologic and ultrastructural study.

Sixteen patients with pseudarthrosis of the tibia and one of the radius were evaluated clinically, radiograpically, and microscopically and separated into 3 groups; 8 had neurofibromatosis clinically, 3 had fibrous dysplasia histologically, and 6 had no evidence of either neurofibromatosis or fibrous dysplasia. Prognosis and therapy were determined by correlated clinical, radiographic, and histological observations. Fracture before age 2 years carried a poor prognosis. Electron microscopy allowed neither differentiation among these fibrous lesions, nor any clue to their origin, nor did it support the concept of a neural or vascular derivation.

[A case report: pseudarthrosis of the os lunato-triquetrum?].

The reported case is in its development, diagnostic, course, and legal aspect so extraordinary, that an explicit report is justified. The patient complained of pain in his right wrist region some days following an unusual work with a drilling machine for eight days. The X-rays six months later showed an irregular joint space between the lunate and triquetrum bone, while on his left wrist a synostosis between these bones was found. These changes seemed to be suspicious for a pseudarthrosis of a congenital synostosis, but this diagnosis led to a six years' controversy in several legal procedures. The different interpretations (judgements) by the attending doctors, specialists, and judicial experts, show again the importance of an exact early documentation with sufficient primary X-rays, eventually with comparison of the other hand. During treatment, nothing should be left undone which could support or refute especially an unusual diagnosis.

[Treatment of infected tibial fractures and pseudarthrosis using an external fixator].

The clinical course and the results of our treatment of 18 patients with External Fixator after infection or pseudarthrosis are demonstrated. On an average of 6.1 months the patients wore the external fixator, the time of consolidation of the fracture was 17.2 months from the accident. At the date of examination - 16 months to 10 years after removal the external fixator all fractures and pseudarthroses were united. Two patients still had a fistula three years after removal of the external fixator. Three patients had slight pain in the area of the former fracture or the complication-wound; disturbance of sensibility in the area of the scar and the meshgrafts were found at 11 patients. The mobility of the knee joint was nearly free in all patients, the mobility of the ankle joint was impaired in most of them.

Experimental model of electric stimulation of pseudarthrosis healing.

The effect of electric stimulation with direct constant current in induced pseudarthrosis was investigated in the radius of adult dogs. Two surgical techniques for inducing nonunion in the lower third of the radius of adult dogs are also described. Results were evaluated by clinical, radiologic, and histologic examinations and by 99mTc scintillation. A total of 57 animals (41 electrically stimulated and 16 control animals) was used. Statistically significant data show activation of endochrondral ossification and bone union by electric stimulation.

The Syme amputation in patients with congenital pseudarthrosis of the tibia.

Eight patients with congenital pseudarthrosis of the tibia had a Syme amputation and were followed for an average of 5.9 years. The average age at amputation was 8.2 years, and an average of 3.8 surgical procedures were performed prior to the amputation in each patient. None of the pseudarthroses healed, but in spite of that the Syme amputation can be recommended when amputation is necessary. With a simple orthosis, the child can then engage in normal activities. The operation provides a longer stump than do conventional amputations, as well as better skin coverage and more potential for further growth of the tibia from the distal epiphysis.

[Comments on pseudarthrosis of the cuneonavicular joint (author's transl)].

This paper reports on the result of central bone chip bolting in the treatment of pseudarthrosis of the cuneonavicular joint, using an autologous bone chip according to the method evolved by Wilhelm and Sperling. The surgical procedure and postoperative course are described in detail, as well as the findings of a followup check effected two years later.

Treatment of delayed union and pseudarthrosis by low frequency pulsing electromagnetic stimulation. Study of 35 cases.

This is a study of 35 cases of delayed union or established fibrous union ("pseudarthrosis") treated by pulsing electromagnetic stimulation. The treatment, applied up to 12 hours per day, can be carried out at home, with clinical and radiological control every 60 days. The average time of healing was 6 months. Consolidation occurred in 88.5% of cases, usually without the production of excessive periosteal callus. The method was particularly useful and effective in infected fractures, failed bone grafts, revascularisation of fragments showing signs of necrosis, and fractures with associated skin lesions.

Pseudarthrosis of the clavicle. A case report.

Congenital pseudarthrosis of the clavicle is a rare condition usually affecting the right side. The causation is unknown, but it is probably due to an environmental factor such as fetal position and excessive pressure from the subclavian artery. The embryology of the clavicle is discussed, and the differential diagnosis and treatment are described. A case occurring in a 12-year-old girl is reported.

Congenital pseudarthrosis of the tibia. Factors that affect results.

Congenital pseudarthrosis of the tibia is a rare disease of unknown etiology and variable natural history. Treatment offers a high percentage of poor results. The decision of when the limb will be cosmetically and functionally better than a below-knee prosthesis is a critical one that the orthopedic physician must reach with the patient. The presence or absence of neurofibromatosis apparently does not alter the result. Those cases which show a cystic radiographic appearance have a more favorable prognosis than those which become or present as dysplastic. The more times the patient is bone grafted without success, the worse the result is likely to be. Shortening of the limb is not only important from a functional standpoint but may also serve as a prognostic index for the difficulty of achieving union as well as subsequent problems with ankle stiffness, pain, and deformity. The response to grafting may also be an important factor in determining the result; those patients who rapidly resorb the graft have a poor chance for a successful outcome. It does not appear that the type of bone grafting procedure is of large significance unless the graft has its own blood supply. Although prophylactic grafting cannot be demonstrated to alter the natural history of this disease, it, along with other developmental techniques, may be advisable.

Congenital pseudarthrosis of the tibia. Three cases treated by free vascularized iliac crest graft.

Three patients with congenital pseudarthrosis of the tibia were successfully treated by free microvascularized iliac crest grafts. All three patients had had two unsuccessful internal fixation reconstruction operations. Union occurred rapidly between the resected bone ends and the vascularized bone graft. Although the fibula has more often been used as a vascularized free graft, the ilium is a better source of bone for bridging small gaps.

[Suppurative pseudarthrosis treated by closed, irrigated corticospongious grafts. New technique derived from Papineau's procedure (author's transl)].

The treatment of suppurative pseudarthrosis, particularly in the leg after extensive tibial resection, remains very difficult and exceedingly slow. In the new technique described--which derives from, and improves upon Papineau's procedure--granular micrografts of cortical and spongious bone tissues are laid under a tightly closed sterile tent, and continuous irrigation and aspiration are applied. In 10 patients treated by this technique highly satisfactory results were obtained, bone consolidation being achieved within 8 months on average.

Surgical treatment of congenital pseudarthrosis of the tibia.

Dual tibiofibular intramedullary rodding with autogenous bone grafting is our treatment of choice in congenital pseudarthrosis of the tibia. The method has a high incidence of primary union. The intramedullary rods control angulation and protect against refracture without hindering growth, and they permit strengthening of the union on weight-bearing. A comprehensive treatment program must address the simultaneous problems of achieving and maintaining bone and joint alignment as well as effective osteogenesis.

Treatment of congenital pseudarthrosis of the tibia with free vascularized bone graft.

Considering the often poor results obtained with conventional methods of bone grafting in the treatment of congenital pseudarthrosis of the tibia, the free vascularized bone graft may offer the best chance of cure to these unfortunate patients. A segment of rib or fibula may be harvested with its vascular supply and used as a graft to the involved segment of the tibia, using microvascular techniques to anastomose its vasculature to that of the affected leg. The advantages of this approach include a one stage procedure with minimal hospitalization, and a minimal donor defect especially when the rib is used. Although the procedure is time consuming the overall operative effort is far less than that of multiple procedures often needed with conventional methods of grafting. Although published reports are few, preliminary reports from microsurgeons using this technique indicate a high success rate, even after previous failures of conventional grafts. The increasing use of microvascular free bone transfers may eliminate the need for amputation in many of these children.

Pathology and natural history of congenital pseudarthrosis of the tibia.

Of the six types of congenital pseudarthrosis, Type II is the most common and lends to poorest prognosis. The basic pathology is an aggressive osteolytic fibromatosis. Failures in these patients are due to recurrence of the osteolytic fibromatosis, which can remove living bone or a dead bone graft. Type III cases have a better prognosis. The gross pathology is a bone cyst, and the microscopic findings resemble fibrous dysplasia. After surgical treatment, generally, the older the child the better the prognosis. Recurrences are rare after skeletal maturity.

Osteosynthesis with Rush's double nail by the "Eiffel Tower" method in pseudarthrosis impacted in good position and retarded union.

The "Eiffel Tower" method of nailing has not attracted the interest in Italy that it deserves, both because its utilisaton in fractures is difficult when closed reduction of the fragments is difficult, and because the attention of surgeons has been progressively directed towards osteosynthesis by open reduction. Our experience over many years, however, has convinced us that, in the diaphysis, only the intramedullary nail can provide the quick recovery that is not always forthcoming in the case of plating. We need only think of comminuted fractures, where the possible necrosis of one or more fragments demands a certain amount of prudence in allowing direct weight bearing. Therefore, in adopting the double Rush system, we extended its application to the intramedullary osteosynthesis of metaphyseal fractures. It was a short step from this to the surgical treatment of pseudarthrosis impacted in good position or retarded union, the results of which were encouraging, as demonstrated by the eighty-one cases reported in this paper.

[Congenital pseudarthrosis of the clavicle: roentgenographic appearance and discussion of the aetiological and pathogenetical theories [author's transl].

The authors briefly reviewed the anatomic and radiological pattern of the congenital pseudarthrosis of the clavicle, with the main aetiological and pathogenetical theories. They also report their personal experience about 2 patients, stressing the peculiarity of this affection compared with others similar in their radiological pattern. They underline the coexistence, in one of the two cases, of the Ehlers-Danlos syndrome, suggesting a single vascular aetiology and pathogenesis.
