As an alternative to external fixators, intramedullary lengthening nails (ILNs) can be employed for distraction osteogenesis. While previous studies have demonstrated that typical complications of external devices, such as soft-tissue tethering, and pin site infection can be avoided with ILNs, there is a lack of studies that exclusively investigated tibial distraction osteogenesis with motorized ILNs inserted via an antegrade approach. A total of 58 patients (median age 17 years (interquartile range (IQR) 15 to 21)) treated by unilateral tibial distraction osteogenesis for a median leg length discrepancy of 41 mm (IQR 34 to 53), and nine patients with disproportionate short stature treated by bilateral simultaneous tibial distraction osteogenesis, with magnetically controlled motorized ILNs inserted via an antegrade approach, were retrospectively analyzed. The median follow-up was 37 months (IQR 30 to 51). Outcome measurements were accuracy, precision, reliability, bone healing, complications, and patient-reported outcome assessed by the Limb Deformity-Scoliosis Research Society Score (LD-SRS-30).Aims
Methods
We report 79 cases of bone and joint tuberculosis between 1988 and 2005, eight of which were in the Caucasian population and 71 in the non-white population. The diagnosis was made in the majority (73.4%) by positive bacteriology and/or histology. The mean age at the time of diagnosis was higher in the Caucasian group at 51.5 years (28 to 66) than in the South Asian group at 36.85 years (12 to 93). Only one patient had previous BCG immunisation. The spine was the site most commonly affected (44.3%). Surgical stabilisation and/or
The aim of this study was to characterize the relationship between pre- and postoperative opioid use among patients undergoing common elective orthopaedic procedures Pre- and postoperative opioid use were studied among patients from a national insurance database undergoing seven common orthopaedic procedures using univariate log-rank tests and multivariate Cox proportional hazards analyses.Aims
Patients and Methods
The aim of this paper was to present the clinical features of
patients with musculoskeletal sources of methicillin-sensitive A total of 137 patients presented with MSSA septicaemia between
2012 and 2015. The primary source of infection was musculoskeletal
in 48 patients (35%). Musculoskeletal infection was considered the
primary source of septicaemia when endocarditis and other obvious
sources were excluded. All patients with an arthroplasty at the time
were evaluated for any prosthetic involvement. Aims
Patients and Methods
Fresh-frozen allograft bone is frequently used
in orthopaedic surgery. We investigated the incidence of allograft-related
infection and analysed the outcomes of recipients of bacterial culture-positive
allografts from our single-institute bone bank during bone transplantation.
The fresh-frozen allografts were harvested in a strict sterile environment
during total joint arthroplasty surgery and immediately stored in
a freezer at -78º to -68º C after packing. Between January 2007
and December 2012, 2024 patients received 2083 allografts with a
minimum of 12 months of follow-up. The overall allograft-associated
infection rate was 1.2% (24/2024). Swab cultures of 2083 allografts
taken before implantation revealed 21 (1.0%) positive findings.
The 21 recipients were given various antibiotics at the individual
orthopaedic surgeon’s discretion. At the latest follow-up, none
of these 21 recipients displayed clinical signs of infection following
treatment. Based on these findings, we conclude that an incidental positive
culture finding for allografts does not correlate with subsequent
surgical site infection. Additional prolonged post-operative antibiotic
therapy may not be necessary for recipients of fresh-frozen bone
allograft with positive culture findings. Cite this article:
We report the results of six trauma and orthopaedic
projects to Kenya in the last three years. The aims are to deliver both
a trauma service and teaching within two hospitals; one a district
hospital near Mount Kenya in Nanyuki, the other the largest public
hospital in Kenya in Mombasa. The Kenya Orthopaedic Project team
consists of a wide range of multidisciplinary professionals that
allows the experience to be shared across those specialties. A follow-up
clinic is held three months after each mission to review the patients.
To our knowledge there are no reported outcomes in the literature
for similar projects. A total of 211 operations have been performed and 400 patients
seen during the projects. Most cases were fractures of the lower
limb; we have been able to follow up 163 patients (77%) who underwent
surgical treatment. We reflect on the results so far and discuss
potential improvements for future missions.
A total of 38 patients with leprosy and localised nerve damage (11 median at the wrist and 37 posterior tibial at the ankle) were treated by 48 freeze-thawed skeletal muscle autografts ranging between 2.5 cm and 14 cm in length. Sensory recovery was noted in 34 patients (89%) and was maintained during a mean period of follow-up of 12.6 years (4 to 14). After grafting the median nerve all patients remained free of ulcers and blisters, ten demonstrated perception of texture and eight recognised weighted pins. In the posterior tibial nerve group, 24 of 30 repairs (80%) resulted in improved healing of the ulcers and 26 (87%) demonstrated discrimination of texture. Quality of life and hand and foot questionnaires showed improvement; the activities of daily living scores improved in six of seven after operations on the hand, and in 14 of 22 after procedures on the foot. Another benefit was subjective improvement in the opposite limb, probably because of the protective effect of better function in the operated side. This study demonstrates that nerve/muscle interposition grafting in leprosy results in consistent sensory recovery and high levels of patient satisfaction. Ten of 11 patients with hand operations and 22 of 25 with procedures to the foot showed sensory recovery in at least one modality.
Bone-marrow oedema can occur both in isolation and in association with necrosis of bone, but it has not been shown whether each respond to the same methods of treatment. We treated 16 patients with isolated oedema and 17, in which it was associated with necrosis of the proximal femur, with the prostacyclin derivative iloprost, which has been shown to be effective in the idiopathic form. The Harris hip score, the range of movement, the extent of the oedema as measured by MRI, pain on a visual analogue scale and patient satisfaction were recorded before and subsequent to treatment. In both groups, we were able to show a significant improvement (p <
0.001) in these observations during the period of follow-up indicating that iloprost will produce clinical improvement in both circumstances.
The aim of this study was to re-assess whether the use of a ‘one-knife technique’ can be considered as safe as the alternative practice of using separate skin and inside knives for elective orthopaedic surgery. A total of 609 knife blades from 203 elective orthopaedic operations, with equal numbers of skin, inside and control blades, were cultured using direct and enrichment media. We found 31 skin blades (15.3%), 22 inside blades (10.8%), and 13 control blades (6.4%) gave bacterial growth. Of the 31 contaminated skin blades only three (9.7%) had growth of the same organism as found on the corresponding inside blade. It is not known whether contamination of deeper layers in the remaining 90% was prevented by changing the knife after the skin incision. The organisms cultured were predominantly coagulase-negative staphylococci and proprionibacterium species; both are known to be the major culprits in peri-prosthetic infection. Our study suggests that the use of separate skin and inside knives should be maintained as good medical practice, since the cost of a single deep infection in human and financial terms can be considerable.
Injury to the sciatic nerve is one of the more serious complications of acetabular fracture and traumatic dislocation of the hip, both in the short and long term. We have reviewed prospectively patients, treated in our unit, for acetabular fractures who had concomitant injury to the sciatic nerve, with the aim of predicting the functional outcome after these injuries. Of 136 patients who underwent stabilisation of acetabular fractures, there were 27 (19.9%) with neurological injury. At initial presentation, 13 patients had a complete foot-drop, ten had weakness of the foot and four had burning pain and altered sensation over the dorsum of the foot. Serial electromyography (EMG) studies were performed and the degree of functional recovery was monitored using the grading system of the Medical Research Council. In nine patients with a foot-drop, there was evidence of a proximal acetabular (sciatic) and a distal knee (neck of fibula) nerve lesion, the double-crush syndrome. At the final follow-up, clinical examination and EMG studies showed full recovery in five of the ten patients with initial muscle weakness, and complete resolution in all four patients with sensory symptoms (burning pain and hyperaesthesia). There was improvement of functional capacity (motor and sensory) in two patients who presented initially with complete foot-drop. In the remaining 11 with foot-drop at presentation, including all nine with the double-crush lesion, there was no improvement in function at a mean follow-up of 4.3 years.
