To demonstrate experience of bone transport arthrodesis of the knee with simultaneous lengthening in the treatment of infected peri-articular fracture fixation associated with large condylar defects. Four patients (3 male/1 female), mean age 46.5 years (37–57 y) with post-traumatic osteomyelitis involving the knee were treated by radical debridement, removal of all metalwork and frame application. Substantial condylar defects resulted (6–10 cm) with loss of extensor mechanism. Parenteral antibiotics were administered for several weeks. Two patients required muscle flaps. Bone transport was utilised to achieve an arthrodesis whilst simultaneously lengthening. In three cases a ‘peg in socket’ construct was fashioned to ensure stability of the arthrodesis.Purpose
Methods
We describe a minimally invasive technique that permits intra-focal bone graft of non-union sites with minimal disturbance of soft tissues and vascularity, and present the results of this technique. 10 patients with established tibia fracture non-union were judged suitable for the technique, and were treated in our limb reconstruction unit between January 1995 to June 2007. Eight patients were male, 2 were females with a mean age of 37.4 years (27–64). Five fractures were in the distal tibia and five were diaphyseal fractures. Five fractures were as a result of high velocity and 6 fractures were open. Average number of previous operations were 3 (range 1–7). Time lapse between injury to trephine grafting procedure was mean of 34 (6–168 months) 5 patients had a sedentary job, 2 were labourers and 2 were not working. There were 5 smokers and 2 obese patients. Six cases were of infected non-unions.Introduction
Materials and Methods
(1) To determine whether any difference exists in AVN risk between surgical reduction [Fish] or pinning-in-situ [PIS] of severe slips. (2) To review the different classifications of SUFE in relation to AVN. 56 children presented with slipped upper femoral epiphysis (SUFE) from 1998 to 2008; 29 males, 27 females; mean age 12.8 years. The Loder & Southwick classifications were used. All slips were treated surgically. The mild and moderate groups were treated with a single pin-in-situ. The severe group had either surgical reduction [Fish femoral neck osteotomy], alternatively a single pin-in-situ, randomised by day of admission. Avascular necrosis of the femoral head (AVN) was the primary outcome measurement.Aim
Materials and Methods
To analyse the results of the use of Recombinant Bone Morphogenic Protein (BMP-7) for treatment of fracture nonunions at our institution. From 2001 to 2006, 23 patients with fracture nonunion were treated with BMP-7 for bone healing. There were 14 male and 9 females. The mean age of patients was 45 years (Range 21-76 yrs). There were 11 femoral, 9 tibial and 3 humerus fractures. There were 4 open injuries. The average number of operations before BMP-7 insertion was 2.66 (Range 0-6). The mean time between the injury and BMP insertion was 54 months (Range 5-312). 9 patients had previous autologous bone graft inserted without union.Aim
Material and methods
We reviewed 78 femoral and tibial non-unions treated between January 1992 and December 2003. Of these, we classified 41 as complex non-unions, because of infection (22), bone loss or prior failed surgery to produce union. These were treated with Ilizarov frames. 39 of the 41 nonunions healed successfully at a median time of 11 months. Using the ASAMI scoring system, we had 17 excellent, 14 good, 4 fair and 6 poor bone results. The functional results were excellent in 14, good in 14, fair in 2 and poor in 2. All but 2 patients were extremely satisfied with the results. The average cost of treatment to the treating hospital was approximately £30,000 per patient. In comparison the cost for a patient with a below-knee amputation was £999 per year. This would amount to a cost of £36,000 per patient in their lifetime. There is therefore not a great difference between the cost of limb salvage and amputation. The difference that exists favours limb salvage, if patient selection can accurately predict the salvage of a useful limb. Early referral to tertiary centres would reduce the morbidity and the prolonged time off work. The results justify the expense but the NHS needs to make financial provision for reconstruction of complex nonunions.
