We present a retrospective review of patients treated with extracorporeally
irradiated allografts for primary and secondary bone tumours with
the mid- and long-term survivorship and the functional and radiographic
outcomes. A total of 113 of 116 (97.4%) patients who were treated with
extracorporeally irradiated allografts between 1996 and 2014 were
followed up. Forms of treatment included reconstructions, prostheses
and composite reconstructions, both with and without vascularised
grafts. Survivorship was determined by the Kaplan-Meier method.
Clinical outcomes were assessed using the Musculoskeletal Tumor
Society (MSTS) scoring system, the Toronto Extremity Salvage Score
(TESS) and Quality of Life-C30 (QLQ-30) measures. Radiographic outcomes
were assessed using the International Society of Limb Salvage (ISOLS)
radiographic scoring system.Aims
Patients and Methods
Retrograde femoral nailing is gaining in popularity. We report a prospective, randomised comparison of antegrade and retrograde procedures in 68 patients with 69 fractures of the femoral shaft. All nails were inserted after appropriate reaming. There was no difference in operating time, blood loss, technical complications, size of nail or reamer, or transfusion requirements. There were more problems of length and rotation using a retrograde technique on a radiolucent table than with an antegrade approach on a fracture table. All fractures in both groups healed and there was no difference in the time taken to achieve
The incidence of refracture following the removal of screws and plates from the diaphyses of 115 forearm bones in 80 patients has been studied. Refracture occurred in four adult patients as a result of minimal trauma, in two patients at the original fracture site after premature plate removal, at the site of a countersunk interfragmentary screw in one and at the original fracture site in another who had required three operative procedures to achieve '
We present a series of ten hypertrophic nonunions in which bony alignment and length were restored and
Although it has been well established that fracture healing is influenced by the mechanical environment, the optimal parameters have not yet been established. In two groups of sheep an experimental tibial diaphysial fracture was created, and stabilised using external skeletal fixation. In one group rigid fixation was maintained throughout fracture healing; in the other group controlled axial micromovement, with a loading regime known to be osteogenic in intact bones, was applied for a short period daily. A significant improvement in healing was associated with the application of controlled micromovement. Data from these experiments provide the basis for improving the conditions for fracture healing and may assist in the prevention of delayed
Fourteen cases of pseudarthrosis of the tibia in childhood presented at a hospital in Burma over a period of eight years. The ages of the patients ranged from one month to seventeen years. Nine were treated by a pointed graft driven into the medullary cavity of the distal tibia, and usually across the ankle joint into the body of the talus, before fixation to the proximal tibia. In six of the nine
Retrosternal displacement of the medial aspect of the clavicle after physeal fracture is rare. We treated six patients with this injury between 1995 and 1998, all as an emergency in order to avoid complications associated with compression of adjacent mediastinal structures. Attempted closed reduction was undertaken, but all required open reduction and internal fixation using a wire suture. There were no associated complications. Five were reviewed clinically and radiologically at a minimum of one year after operation. All had regained full use of the affected arm without pain and had resumed their preinjury level of activity including sports. Follow-up radiographs showed
We performed a prospective, randomised trial in 39 patients with open tibial fractures treated initially by external fixation to compare cast immobilisation (group A) and intramedullary nailing (group B) as a sequential protocol planned from the onset of treatment. The results showed that group B achieved faster
We have prospectively compared the fixation of 100 intertrochanteric fractures of the proximal femur in elderly patients with random use of either a Dynamic Hip Screw (DHS) or a new intramedullary device, the Gamma nail. We found no difference in operating time, blood loss, wound complications, stay in hospital, place of eventual discharge, or the patients' mobility at final review. There was no difference in failure of proximal fixation: cut-out occurred in three cases with the DHS, and twice with the Gamma nail. However, in four cases fracture of the femur occurred close to the Gamma nail, requiring further major surgery. In the absence of these complications,
We present the results of using the Grosse-Kempf interlocking nail in the management of 125 closed and type I open tibial fractures. The mean time to
Nine children sustained a second fracture of the distal humerus after
We report the use of elastic stable intramedullary nailing (ESIN) in 123 fractures of the femoral shaft in children. Flexible rods are introduced through the distal metaphyseal area, and the aim is to develop bridging callus. Early weight-bearing is possible and is recommended. There was one case of bone infection and no delayed
Fifty-six patients with displaced malleolar fractures had open reduction and fixation of the fracture fragments using, by random selection, either biodegradable implants or metal AO plates and screws. The cylindrical biodegradable implants were made of polylactide-glycolide copolymer (polyglactin 910). The complications, radiographic results and functional recovery were studied prospectively. After follow-up of at least one year, no significant differences emerged in the complication rate or in the results of treatment between the two methods of fixation. Because of the advantage of avoiding the need to remove metal fixation after
We reviewed 63 patients with fractures of the distal tibial metaphysis, with or without minimally displaced extension into the ankle joint. The fractures had been caused by two distinct mechanisms, either a direct bending force or a twisting injury. This influenced the pattern of the fracture and its time to
Fifty-three ununited fractures with a median time since injury of 28 months were treated by electrical stimulation using pulsing electromagnetic fields.
Twenty complex tibial deformities due to anterior poliomyelitis in 18 patients were corrected by a modified O’Donoghue osteotomy. This technique allowed correction of the deformity in three planes. This was achieved by widening the rectangular window distally to correct both rotation and valgus and by trimming the anterior edges of the step cuts to correct flexion deformity. An above-knee cast was applied for eight to 13 weeks and the patients followed up for a mean of 3.2 years. One of the 18 patients developed delayed
Diabetes mellitus (DM) is known to impair fracture healing. Increasing evidence suggests that some microRNA (miRNA) is involved in the pathophysiology of diabetes and its complications. We hypothesized that the functions of miRNA and changes to their patterns of expression may be implicated in the pathogenesis of impaired fracture healing in DM. Closed transverse fractures were created in the femurs of 116 rats, with half assigned to the DM group and half assigned to the control group. Rats with DM were induced by a single intraperitoneal injection of streptozotocin. At post-fracture days five, seven, 11, 14, 21, and 28, miRNA was extracted from the newly generated tissue at the fracture site. Microarray analysis was performed with miRNA samples from each group on post-fracture days five and 11. For further analysis, real-time polymerase chain reaction (PCR) analysis was performed at each timepoint.Objectives
Methods
We used the Ilizarov circular external fixator to treat 16 patients with persistent nonunion of the diaphysis of the humerus despite surgical treatment. All patients had pain and severe functional impairment of the affected arm. In ten, nonunion followed intramedullary nailing. We successfully treated these by a closed technique. The nail was left in place and the fracture compressed over it. The fractures of the other six patients had previously been fixed by various methods. We explored these nonunions, removed the fixation devices and excised fibrous tissue and dead bone before stabilising with the Ilizarov fixator. In five patients
Forty comminuted or unstable fractures of the femoral shaft were treated by closed intramedullary reaming and locked nailing. Twenty-four fractures were severely comminuted, and the other 16, in the distal or proximal third of the shaft, were classified as unstable. At 12 to 30 months postoperatively all the fractures had healed. Three patients had lateral rotation deformity of 5 degrees to 10 degrees, three had shortening of 1 to 2 cm and two had lengthening of about 1 cm. There were no infections or delayed
