Camptodactyly is a flexion deformity of the proximal interphalangeal joint. Because of unsatisfactory results, treatment is
not recommended for mild deformities, and in severe deformities surgery has been disappointing. A specially designed external
fixator providing gradual distraction was used in a severe case. With this mildly aggressive method, an acceptable result
was obtained.

In the present study, a kinematic analysis was made of unconstrained, natural prehension movements directed toward an object
approaching the observer on a conveyor belt at one of three constant velocities, from one of three different directions (head-on
or along the fronto-parallel plane coming either from the subject′s left or right). Subjects were required to grasp the object
when it reached a target located 20 cm directly in front of the hand′s start position. The kinematic analysis revealed that
both the transport and grasp components of the movement changed in response to the experimental manipulations, but did so
in a manner that guaranteed that, for objects approaching from a given direction, hand closure would begin at a constant time
prior to object contact (regardless of the object’s approach speed). The kinematic analysis also revealed, however, that the
onset of hand closure began earlier with objects approaching from the right than from other directions – an effect which would
not be predicted if time to contact was the key variable controlling the onset of hand closure. These results, then, lend
only partial support to the theory that temporal coordination between the transport and grasp components of prehension is
ensured through their common dependence on time to contact information.

The reverse U incision method has been employed for the correction of the unilateral cleft lip nose deformity for more than twenty years with satisfactory results. It has some columella lengthening effect and thus has proved to be useful for the correction of nasal deformities of bilateral cleft lip. To augment its columella lengthening effect a columella relaxation incision is added to the bilateral reverse U incision for the correction of the bilateral cleft lip nose deformity. This results in a reconstructed columella of satisfactory length and width. 相似文献

Summary A case of Turner's syndrome with the typical marked webbing of the neck is presented. A posterior approach is preferred for correction of this webbed neck deformity. A butterfly shaped portion of excess skin is excised and the margins of the defect mobilised as four flaps. The flaps are sutured with a very short midline vertical component, resulting in an almost X-shaped scar. The first procedure resulted in only a partial correction of the deformity and an excess of hypertrophic scar tissue. This was treated with a repeat of the procedure but the midline wounds was repaired with mulitple small Z-plasties. The final appearance of the neck was satisfactory in the lateral profile, but there was still some excess tissue posteriorly. 相似文献

In addition to estrogen widely used all over the world for the prevention of postmenopausal osteoporosis, calcitonin and vitamin
D derivatives are commonly employed to treat established osteoporosis at higher age in Japan. In order to critically assess
the usefulness of vitamin D derivatives and calcitonin alone or in combination on the advancement of vertebral deformity at
higher age, 32 osteoporotic patients with vertebral deformity with the mean age of 79 were randomly divided into 4 groups
with indistinguishable age and severity of the vertebral deformity. Group 1 served as the control without specific medications
for osteoporosis. Group 2 was treated with 10 units elcatonin (eel calcitonin derivative) injected intramuscularly twice a
week. Group 3 was given 0.75 to 1.5μg/day 1α (OH) vitamin D3 orally. Group 4 was given a combination of treatments used in Groups 2 and 3.
In the lateral X-ray film of the spine taken prior to the test and every 6 months thereafter, the shape of the vertebral body
T8 through L4 was monitored by measuring the anterior, central and posterior heights. Decrease of the vertebral height ratio; anterior
or middle height/posterior or adjacent intact posterior height, by more than 20% of the original value or from above to below
0.80 both appeared to be inhibited during administration of 1α (OH) vitamin D3. Such effect seems to be augmented by simultaneous administration of elcatonin. Actual decrease of vertebral height ratio
values and the per cent fall from the original value significantly less in Groups 3 and 4 than in Group 1. Development of
vertebral deformity assessed by the changes of the vertebral height thus appears to decrease during treatment with 1α (OH) vitamin D3 especially together with calcitonin in established osteoporosis. 相似文献

MR imaging based strategies in limb salvage surgery for osteosarcoma of the distal femur 总被引:6,自引:0,他引:6

Objective. To analyse to what extent MR imaging based decisions were correct in determining the surgical procedure in patients with
osteosarcoma of the distal femur. Design. We compared the findings on MR imaging that determined the surgical strategy with the actual surgical findings or histopathological
specimen. We assessed to what extent MR images could be used to determine the surgical procedure in patients with osteosarcoma.
Patients. Between 1985 and 1992, 34 patients with an osteosarcoma were treated. Two patients had a low-grade osteosarcoma. Thirty-two
patients with a high-grade osteosarcoma of the distal femur (17 stage IIB, 15 stage III) were included in this study. Surgical
options consisted of either limb salvage surgery or ablative surgery, which included the Van Nes-Borggreve rotationplasty.
Limb salvage surgery consisted of extra-articular or transarticular resection, followed by reconstruction. Surgery was planned
depending on the local extent of the tumour as depicted on the MR studies, coupled with data from the biopsy, age, patient
compliance and histological grade. Follow-up was available in all patients. Nine of 17 patients graded as IIB were alive with
an average follow-up of 68 months (range 46–109 months), of whom one has metastases. No local recurrence was encountered.
Results. If no tumour involvement on MR imaging was found and this was used as a determining factor, this proved to be correct at
subsequent analysis. We found that in eight of 11 cases, when MR images suggested a close relationship between tumour and
nerve, an oncologically safe plane could be achieved during surgery. In three, a free plane could not be accomplished, as
confirmed at histopathological examination. Hence, when nerve involvement was equivocal on MR imaging we found it valuable
to reassess nerve involvement during surgery and reconsider limb salvage surgery. When the decisive factor was the vascular
involvement and tumour extension was read as equivocal, it was possible to obtain a oncologically safe plane in six of 13
cases. When comprehensive tumour involvement of any structure was noted pre-operatively, it proved to be correct at histopathological
examination, except for one case of assumed vascular involvement that proved to be free. Conclusions. If no tumour involvement of a structure was found on MR imaging and this was used as a determining factor, this proved to
be correct. When nerve involvement was equivocal on MR imaging we found it valuable to reassess nerve involvement during surgery
and reconsider limb salvage surgery. Extensive tumour involvement of any structure, as shown by MR imaging, could be used
correctly as a decisive argument in planning a surgical procedure. 相似文献

This article describes plastic surgery patients who sought symmetrical recontouring of the width of the face and skull. The basic demographic and personality characteristics of these facial width deformity (FWD) patients and the surgical procedures performed on them are discussed. Details of the surgical and psychological management of three representative cases are given. Speculative conclusions regarding the general characteristics of the FWD population are offered. Suggestions are proposed for a combined surgical-medical psychotherapeutic collaboration in managing these patients. 相似文献
