From 1990 to 1993 we treated 22 consecutive patients who had progressive spinal kyphosis due to ankylosing spondylitis by a closing-wedge
The purpose of this study was to examine the effect of posterior
cruciate ligament (PCL) retention, PCL recession, and PCL excision
during cruciate-retaining total knee replacement. A total of 3018 anatomic graduated component total knee replacements
were examined; 1846 of these retained the PCL, 455 PCLs were partially
recessed, and in 717 the PCL was completely excised from the back
of the tibia.Objectives
Methods
We report the results of a new surgical procedure for spastic equinovarus deformity due to cerebral palsy. This is the transfer of the anterior half of the split tibialis
A prospective study to investigate changes in the rib hump or rib deformity after correction of the lateral curvature in adolescent idiopathic scoliosis is reported. The operative treatment for 47 patients was by a Harrington distraction rod and
Flexor digitorum longus transfer and medial displacement
calcaneal osteotomy is a well-recognised form of treatment for stage
II posterior tibial tendon dysfunction. Although excellent short-
and medium-term results have been reported, the long-term outcome
is unknown. We reviewed the clinical outcome of 31 patients with
a symptomatic flexible flat-foot deformity who underwent this procedure
between 1994 and 1996. There were 21 women and ten men with a mean
age of 54.3 years (42 to 70). The mean follow-up was 15.2 years
(11.4 to 16.5). All scores improved significantly (p <
0.001).
The mean American Orthopedic Foot and Ankle Society (AOFAS) score improved
from 48.4 pre-operatively to 90.3 (54 to 100) at the final follow-up.
The mean pain component improved from 12.3 to 35.2 (20 to 40). The
mean function score improved from 35.2 to 45.6 (30 to 50). The mean
visual analogue score for pain improved from 7.3 to 1.3 (0 to 6).
The mean Short Form-36 physical component score was 40.6 ( Cite this article:
We describe five adolescent patients aged between 13 and 16 years with bipartite ossification of the posteromedial aspect of the talus. All presented without a history of trauma. All the ankles had a similar radiological appearance. Clinically, some restriction of movement was noted in three ankles and two subtalar joints, In addition, pain was noted over the posteromedial aspect of the ankle in three patients. In each patient the bipartite fragment was excised through a posteromedial approach to the ankle. Complete resolution was achieved at six months in three patients, with the remaining two describing exercise-induced symptoms. In one of these this precluded participation in sport. Despite numerous anatomical variations within the tarsus, a case series of a bipartite talus has not previously been reported. This anatomical variation should be recognised to avoid misinterpretation as post-traumatic or other pathological processes. In the presence of recalcitrant symptoms excision is an option, but this is not universally successful in abolishing symptoms.
The femoral head receives blood supply mainly
from the deep branch of the medial femoral circumflex artery (MFCA).
In previous studies we have performed anatomical dissections of
16 specimens and subsequently visualised the arteries supplying
the femoral head in
55 healthy individuals. In this further radiological study we compared
the arterial supply of the femoral head in 35 patients (34 men and
one woman, mean age 37.1 years (16 to 64)) with a fracture/dislocation
of the hip with a historical control group of 55 hips. Using CT
angiography, we identified the three main arteries supplying the femoral
head: the deep branch and the postero-inferior nutrient artery both
arising from the MFCA, and the piriformis branch of the inferior
gluteal artery. It was possible to visualise changes in blood flow
after fracture/dislocation. Our results suggest that blood flow is present after reduction
of the dislocated hip. The deep branch of the MFCA was patent and
contrast-enhanced in 32 patients, and the diameter of this branch
was significantly larger in the fracture/dislocation group than
in the control group (p = 0.022). In a subgroup of ten patients
with avascular necrosis (AVN) of the femoral head, we found a contrast-enhanced
deep branch of the MFCA in eight hips. Two patients with no blood
flow in any of the three main arteries supplying the femoral head
developed AVN. Cite this article:
We report a case of vertebral osteochondroma of C1 causing cord compression and myelopathy in a patient with hereditary multiple exostosis. We highlight the importance of early diagnosis and the appropriate surgery in order to obtain a satisfactory outcome.
We describe the results of surgical treatment in a prospective study of 183 consecutive cases of subluxation (101) and dislocation (82) of the shoulder secondary to obstetric brachial plexus palsy between 1995 and 2000. Neurological recovery was rated ‘good’ or ‘useful’ in all children, whose lesions fell into groups 1, 2 or 3 of the Narakas classification. The mean age at operation was 47 months (3 to 204). The mean follow-up was 40 months (24 to 124). The mean gain in function was 3.6 levels (9.4 to 13) using the Mallet score and 2 (2.1 to 4.1) on the Gilbert score. The mean active global range of shoulder movement was increased by 73°; the mean range of active lateral rotation by 58° and that of supination of the forearm by 51°. Active medial rotation was decreased by a mean of 10°. There were 20 failures. The functional outcome is related to the severity of the neurological lesion, the duration of the dislocation and onset of deformity.
