Radiological imaging is necessary in a wide variety
of trauma and elective orthopaedic operations. The evolving orthopaedic
workforce includes an increasing number of pregnant workers. Current
legislation in the United Kingdom, Europe and United States allows
them to choose their degree of participation, if any, with fluoroscopic procedures.
For those who wish to engage in radiation-prone procedures, specific
regulations apply to limit the radiation dose to the pregnant worker
and unborn child. This paper considers those aspects of radiation protection, the
potential effects of exposure to radiation in pregnancy and the
dose of radiation from common

pre-operative expectations and the outcome of
We evaluated the safety and efficacy of total
knee replacement in patients receiving continuous warfarin therapy. . We identified 24 consecutive patients receiving long-term warfarin
therapy who underwent total knee replacement between 2006 and 2008
and compared them with a group of age- and gender-matched patients
not on long-term anticoagulation. Primary observations were changes
in haemoglobin, transfusion rates and complications. Secondary observations
were fluctuations in the international normalised ratio (INR) and
post-operative range of movement. . There was no significant difference between the two groups in
pre- or post-operative haemoglobin, incidence of transfusion or
incidence of post-operative complications. There were no surgical
delays due to a high INR level. The mean change in INR during the
peri-operative phase was minimal (mean 0.4; . sd. 0.7). There
was no significant difference in the range of movement between the
two groups after day two post-operatively. Current American College of Chest Physicians guidelines recommend
bridging therapy for high-risk patients receiving oral anticoagulation
and undergoing major
Robots have been used in surgery since the late
1980s. Orthopaedic surgery began to incorporate robotic technology
in 1992, with the introduction of ROBODOC, for the planning and
performance of total hip replacement. The use of robotic systems
has subsequently increased, with promising short-term radiological
outcomes when compared with traditional

Between 1980 and 1988, displacement bone-marrow transplantation was performed on 25 children with Hurler's syndrome (type-1 mucopolysaccharidosis). We describe the musculoskeletal development of 11 of the 12 surviving children and the

The prevalence of HIV infection in East Africa has increased rapidly in recent years. We made a prospective study of the incidence of HIV-seropositivity in patients undergoing
We investigated the capacity of patient warming
devices to disrupt the ultra-clean airflow system. We compared the effects
of two patient warming technologies, forced-air and conductive fabric,
on operating theatre ventilation during simulated hip replacement
and lumbar spinal procedures using a mannequin as a patient. Infection
data were reviewed to determine whether joint infection rates were
associated with the type of patient warming device that was used. Neutral-buoyancy detergent bubbles were released adjacent to
the mannequin’s head and at floor level to assess the movement of
non-sterile air into the clean airflow over the surgical site. During
simulated hip replacement, bubble counts over the surgical site
were greater for forced-air than for conductive fabric warming when
the anaesthesia/surgery drape was laid down (p = 0.010) and at half-height
(p <
0.001). For lumbar surgery, forced-air warming generated
convection currents that mobilised floor air into the surgical site
area. Conductive fabric warming had no such effect. A significant increase in deep joint infection, as demonstrated
by an elevated infection odds ratio (3.8, p = 0.024), was identified
during a period when forced-air warming was used compared to a period
when conductive fabric warming was used. Air-free warming is, therefore,
recommended over forced-air warming for
Postoperative deep-vein thrombosis (DVT) is believed to be rare in Asians. We studied 88 consecutive patients in Malaysia who had operations for fracture of the proximal femur or for total hip or knee replacement. No patient had prophylaxis against DVT; bilateral ascending venography was performed between six and ten days after operation. A total of 55 patients (62.5%) showed venographic evidence of DVT. The prevalence was greatest after total knee replacement (76.5%), less after total hip replacement (64.3%) and smallest in the fracture group (50%). One patient developed symptomatic pulmonary embolism. In contrast to other reports from Asia, we found an incidence of postoperative DVT which is similar to that reported in Western populations. This suggests that the present practice of withholding routine prophylaxis against thromboembolism in Asian patients undergoing high-risk
We describe 11 patients with congenital pseudarthrosis of the tibia treated by a free vascularised fibular graft (FVFG) and followed up from 10 to 64 months (mean 38). Bony union was achieved in nine of the 11 cases: two failures required amputation. The mean time for union in the successful cases was five months. Nine of the 11 patients had had an average of four surgical procedures before the FVFG, so the graft was a salvage procedure for which the only alternative was amputation. FVFG is recommended as a primary procedure for the treatment of congenital pseudarthrosis of the tibia if there is a large tibial defect (over 3 cm) or shortening of more than 5 cm. The primary use of this operation is not advised for cases in which standard
Previous studies of the Ilizarov procedure have concentrated on musculoskeletal assessments rather than the opinions of patients. In a prospective trial of 25 consecutive patients, we evaluated the effect of Ilizarov reconstruction of post-traumatic deformity on general health status using the SF36 and Nottingham Health Profile (NHP). The patients had very low preoperative scores, which remained low during treatment and correction, but increased postoperatively. The mean overall SF36 score improved from 36 ± 3 to 58 ± 7 (p = 0.031) and the NHP score from 39 ± 11 to 67 ± 10 (p = 0.002). The improvements in scores were not limited to the physical components and were equal or better than the improvements reported for other
One hundred and nine children with myelodysplasia were evaluated and classified according to the level and type of paralysis and its effect on functional ability. Thirty-one per cent of the patients were paralysed at the thoracic level, 26% at the upper lumbar level, 30% at the lower lumbar level and 13% at the sacral level. Fifty-four per cent of these patients demonstrated the classic flaccid paralysis in the lower limbs with normal upper limbs; 9% were flaccid in the lower limbs, but were spastic in the upper; 24% were spastic in the lower limbs; 13% were spastic in the upper and lower limbs. Patients with spastic lower limbs required more
