This article is based on the analysis of surgical treatment peculiarities of 641 patients with post-osteomyelitis long bones defects. The average age of patients at the time of hospital admission was 32,4 ± 0,7 and ranged from 4 to 70 years. Most of them were people of active working age (476 (74.3%)) and male (523 (81.1%)). In this observation group 566 (88.3%) patients had the osteomyelitis process of the traumatic origin, including post-surgical (n = 155) and post-gunshot injuries (n = 13). Chronic hematogenous osteomyelitis was diagnosed in 75 (11.7%) patients. Most patients had lower extremity bones problems, including 444 tibia defects and 142 femoral bone defects. Much fewer patients had the osteomyelitis process of the upper extremity (humerus, radius, ulnar bone – 18, 19 and 18 respectively). Purulent necrotic process was accompanied by nonunion bone fragments in 160 (24%) patients, delayed union in 95 (14.6%) patients, false joint in 178 (27.6%) patients, segmental bone defect in 75 (11 5%) patients and bones union with edge defects and cavities in 143 (22.3%) patients. 340 (53%) patients were operated using the method of free bone grafting, and 301 (47%) patients were operated using the distraction method. The need to use the bilocal for external fixation on upper extremities occurs quite seldom (twice in our observations). Even when there is an upper extremity bone defect of several centimeters the preference should be given not to bilocal external fixation. When treating the lower extremities taking the above mentioned into consideration, segmental defects predominated, that is why the bilocal distraction-compression method of surgical treatment prevailed (98.6%). Thus, the main method of upper extremities long bones defects replacement is free bone grafting with segment fixation by the external fixation device, for lower extremities the is not-free main Ilizarov method, which allows to get positive results in 84.6% of patients with femoral bone problems and in 96.4% of tibia problems, mainly due to one-step treatment, directed simultaneously to inflammatory process elimination and maximum possible anatomical and functional restoration of the affected extremity.
Aim. The aim of this systematic review was to determine the reported treatment strategies, their individual success rates, and other outcome parameters in the management of critical-sized bone defects in Fracture-Related Infection (FRI) patients between 1990 and 2018. Method. We performed a systematic literature search on treatment and outcome of critical-sized bone defects in FRI. Treatment strategies identified were, autologous cancellous grafts, autologous cancellous grafts combined with local antibiotics, the induced membrane technique, vascularized grafts, bone transport, and bone transport combined with local antibiotics. Studies describing bone defects of 1 cm or greater were included. Outcomes were bone healing and infection eradication after primary surgical protocol and recurrence of FRI and amputations at the end of study period. Results. Fifty studies were included, describing 1,530 patients, of which the tibia was affected in 82%. The mean age was 40 years (range 6–80), with predominantly male subjects (79%). Mean duration of infection was 17 months (range 1–624) and mean follow-up lasted 51 months (range 6–126). Four studies (8%) described treatment using vascularized grafts, 18 (36%) cancellous grafts, 8 (16%) the induced membrane technique, and 20 (40%) bone transport. A total of 1063 grafts were used of which 30% were vascularized and 60% were cancellous bone. After initial protocolized treatment, FRI was cured in 83% (95% CI 79–87) of all cases, increasing to 94% (95% CI 92–96) at the end of each individual study. Recurrence of infection was seen in 8% (95% CI 6–11) and amputation in 3% (95% CI 2–3). Conclusions. This is the first extensive review of
Purpose. To identify the causes of failure after unicompartmental knee arthroplasty (UKA), and to evaluate considerations for surgical procedures and the results of revision total knee arthroplasty (TKA) performed after failure of UKA. Materials and Methods. Eight hundreds and fifty-two cases of UKA were performed from January 2002 to June 2011. Forty-seven cases of failures after UKA were analyzed for the cause of the failures, and thirty-five cases of revision TKA after failure were analyzed for the operative findings and surgical technique. The clinical results were measured for thirty cases which were followed-up on at least two years after TKA. The mean duration of follow-up was four years and one month after revision TKA and the mean patient age at the time of surgery was sixty-five years. Results. For the cause of failures after UKA, there were twenty-two cases of early loosening of prosthesis, seventeen cases of simple mobile bearing dislocation, five cases of infection, one case of fracture of medial tibial condyle and two cases of unknown origin pain. In operative findings of thirty-five cases of TKA after failed UKA, there were twenty-five cases of
