[Prospective comparison of MRI vs. direct magnification radiography in occult fractures of the scaphoid bone].

The diagnosis of occult fractures of the scaphoid bone is even more challenging than that of conventional fractures of the scaphoid. This study aimed to compare prospectively the gold standard method (plain radiographs in four projections, after about 14 days) and the primary findings with direct magnification radiography (DIMA) and magnetic resonance imaging (MRI). Primary MRI showed much higher diagnostic power than plain radiography at 10-14 days in occult scaphoid fractures and in detection of associated carpal injuries. This may lead to a decreasing time of disease. DIMA was inferior in detecting occult fractures of the scaphoid.

Wedge osteotomy of the lower end of the radius in the treatment of painful pseudarthrosis of the carpal scaphoid bone.

The present authors have had encouraging results in the treatment of painful pseudarthrosis of the carpal scaphoid bone using wedge osteotomy on the lower end of the radius. After the operation, patients experienced restoration of joint movement, less painful or pain-free joints, and, in a few cases, sound union of the established pseudarthrosis of the carpal scaphoid bone. Osteotomy is a simple procedure of short duration and is without complications. In addition, in cases of failure, osteotomy does not exclude other forms of therapy.

[Value of bone scintigraphy in the recognition of scaphoid bone fracture difficult to detect roentgenologically].

Fractures result in increased metabolism of the bone and increased uptake of certain radioisotopes as demonstrated by bone scanning. By comparison, X-rays reveal a fracture only by a disturbance in skeletal structure. In this study, scaphoid fractures which were difficult to detect initially on X-rays were demonstrated by bone scan eight days later. The value of this diagnostic technique was demonstrated in several cases.

[Long-term results of surgically treated scaphoid bone pseudarthrosis].

204 cases of pseudarthrosis of the scaphoid bone have been treated by several operation methods. Reviewing our patients after an average time of 6 years we are able to estimate the results. The Matti-Russe method was the most frequent operative procedure causing good and excellent results. Concerning to the worse blood circulation of the proximale fragment most problems came from the treatment of the necrotic proximale fragment. Using several methods of operation only the early results (up to 3 years) were satisfactory. Within the following years collapsing of the spacers or dislocation of the silicone-implants appeared and loss of function and pain followed. We thought that it is indispensable to find new surgery methods to treat the problematic cases of necrotic proximal fragments by using bone graftings, so that the late results also will be successful.

Fractures of the scaphoid bone. A follow-up study.

Fracture of the scaphoid bone is the most common fracture of the carpal bones (Dunn 1972). Primary diagnosis can be difficult, and misdiagnosis with subsequent inadequate treatment often results in a permanently painful wrist with reduced function of the hand. We have observed that the immobilization time for scaphoid fractures at this clinic is shorter than is usually reported (Cooney et al. 1980; Dunn 1972; Eddeland et al. 1975). We have also observed that in some cases major diastasis in the fractures coincided with delayed union or non-union. Since opinions on the treatment of these fractures have varied on some points, we find it worthwhile to present our results. The major aims of the study were to evaluate whether the short immobilization time has any bearing on the fracture healing and, furthermore, whether the presence of a significant diastasis of the fracture affects the healing.

[Management of painful pseudarthrosis of the carpal scaphoid bone with closed wedge osteotomy of the distal radius: a prospective study with long-term follow-up].

PURPOSE OF THE STUDY: We propose a different management scheme for painful post-traumatic osteoarthritis of the wrist resulting from pseudarthrosis of the carpal scaphoid bone. We report a prospective series with a maximum follow-up of 16 years. MATERIAL AND METHODS: From 1973 to 1990, we performed 100 first-intention wedge osteotomies of the distal radius in patients with painful pseudarthrosis of the carpal scaphoid bone. Inclusion criteria were painful wrists with established pseudarthrosis. The operation consisted in the removal of a small lateral wedge (base f 0.5 cm) without affecting the length of the radius nor the function of the distal radio-ulnar joint. Twenty patients were lost to follow-up and follow-up was less than two years for two. The present series corresponds to 77 patients (all male manual laborers) followed for at least two years. Mean follow-up was 4 years (range 216 years). To evaluate outcome, we developed a devoted scoring system, the Scaphoid Pseudarthosis Hand Score, (SPHS, max 60 points) with items for pain, range of motion, grasping strength, work capacity, wrist function and post-traumatic arthritis. RESULTS: At last follow-up, the SPHS was 45.66 points versus 19.98 before surgery. The pain score was 8.51 versus 3.19: 67 patients (86%) were pain free or experienced mild pain for heavy work. Bone fusion or fibrous union was observed in 49 patients (64%) who were free of post-traumatic osteoarthritis; some improvement of which was observed in 11 other patients (14%) with less sclerotic bone. All patients but two resumed their occupational activities. DISCUSSION: Wedge osteotomy relieves pain and improves hand function by reducing the pressure applied to the radial and scaphoid joint surfaces. It acts positively in the event of post-traumatic arthritis, altering the dynamics of the wrist and producing the beneficial effects of styloidectomy. Although it was not the target, sound union of the pseudarthrosis observed in 25 patients at last follow-up was attributed to the applied treatment.

Congenital proximal radioulnar synostosis associated with bilateral hypoplasia of the scaphoid bone, bilateral os lunatotriquetrum, and anomalies of the carpometacarpal complex.

We describe a unique case of bilateral os lunatotriquetrum associated with bilateral hypoplasia of the scaphoid bone. On both sides, the medial carpi were in a single row. The capitate bone occupied the lunate position, whereas the lunatotriquetral bone was displaced ulnarly and tilted. The capitate thus articulated with the radius and metacarpal bones, consistent with carpal collapse. In addition, there was congenital proximal radioulnar synostosis on the left side.

Ligamentotaxis in pseudarthrosis of the scaphoid bone (preliminary report).

Three cases are reported of pseudarthrosis of the scaphoid bone which have been treated by distraction with an external fixator employing ligamentotaxis. The investigations of Ilizarov and collaborators are discussed, pertaining as they do to stimulation of osteogenesis by distraction. Also considered are the possible indications for use of the method in some unfavourable fresh fractures of the scaphoid.

[Aggressive osteoblastoma of the carpal scaphoid bone].

We report a case of aggressive osteoblastoma of the scaphoid bone and discuss the features of this tumor. The few reported cases emphazise the rarity of osteoblastoma in hand and wrist localizations. Pathological examination is mandatory before treatment due to lack of distinctive clinical and radiological features. In our case, the rapidiy aggressive progression, similar to a malignant tumor, required radical treatment with scaphoïdectomy.

[Development of degenerative changes in the wrist with pseudarthrosis of the scaphoid bone].

In patients with symptomatic scaphoid nonunion there was an increased evidence of progessive osteoarthrosis expressed as instability of the wrist; it is defined as a scapholunate angle more than 70 degrees or a radiolunate angle of more than 10 degrees. We tried to determine the factors of risk and prognostic indicators of degenerative arthritis. In this study 40 patients with painfull nonunion of the scaphoid were analysed. Duration of nonunion was not in correlation with development of osteoarthritic changes (p=0,644; p>0,05). Progessive degenerative changes correlated well with radiolunate angle (p=0,398; p<0,05), kapitolunate angle (p=0,381; p<0,05) and carpal index (p=0,392; p<0,05). The average values of intercarpal angles increased with progression of osteoarthritic changes. There was a statistically strong corelation between location of fracture in proximal third and presence of degenerative changes (p=0,341; p<0,01). Intesity of arthritic changes showed no statistically significant correlation regarding untreated fractures (p=0,665; p>0,05). We recommend that a scaphoid nonunion associated with carpal instability should be operated before degenerative changes develop.

[Fibrin adhesive in the surgical treatment of pseudarthrosis of the scaphoid bone--method and results].

In 50 cases of pseudarthrosis of the scaphoid bone the operative technique of Matti and Russe was applied using fibrin adhesive in addition to a cortico-cancellous bone graft from the iliac crest to secure the fixation of the graft. 48 patients were re-examined. 27% showed bone consolidation after 3 months, 60% after 6 months or more. The total consolidation rate was 87%. It is not quite sure whether the better results are due to fibrin adhesive or not, especially when the consolidation took place after 6 month or more.

[Non-traumatic subluxation of the scaphoid bone of the hand].

It is demonstrated in three clinical case reports that a subluxation of the scaphoid bone and a diastasis between the scaphoid and the lunate can occur in association not only with traumatic injury but with chronic inflammatory conditions of the wrist. In one case the etiology was purulent synovitis, in the 2nd an unspecific synovitis with serous exudate, and in the 3rd case rheumatoid arthritis.
