ABSTRACT

In this study, a retrospective radiological analysis of 112 [95 patients] cemented total hip arthroplasties operated between 1987 and 1994 to determine the relationship between the radiographic variables of the cement mantle geometry in the initial radiographs and the long- term radiographic outcome of cemented femoral components. The results of this study emphasized the importance of the proper selection of the femoral component for implantation with cement in total hip replacements. Templates should be used and a careful preoperative planning should be done to ensure an optimal distal cement mantle. Additionally, the use of distal spacers [centralizers] was suggested, which could help in providing an adequate circumferential cement mantle

ABSTRACT

The aim of this study was to compare the results of intramedullary nailing [IMN] and plating in the treatment of humeral shaft fractures with a particular emphasis on the type and frequency of complications encountered with each technique. Thirty-seven patients were included in the study. Eighteen fractures were fixed with 4.5 mm, AO design, plates and 19 fractures were fixed with an antegrade humeralinter- locking nail. The main clinical assessment measures were shoulder and elbow functions, radial nerve recovery and presence of infection. The radiological assessment was based on fracture alignment, healing time, delayed and nonunion. It was suggested that both plating and IMN provide a satisfactory fixation for humeral shaft fractures with ultimate fracture healing, however IMN is associated with more complications

ABSTRACT

This study included a retrospective clinical and radiographic analysis on a study group of 26 total knee arthroplasties [26 patients] done following failed proximal tibial osteotomies and a control group of 26 total knee arthroplasties [26 patients] without prior osteotomies. The groups were matched according to age, sex, weight, preoperative diagnosis, preoperative limb alignment, type of prosthesis, mode of component fixation and length of follow up. The average length of follow up was 63.2 months [range 49-81 months] in the study group and 62.1 months [range 47-80 months] in the control group. All patients were evaluated according to the clinical rating and the radiological evaluation systems of the Knee Society. The differences between the preoperative and postoperative [last evaluation] scores were assessed with the Student's t-test and Chi-square test. It was suggested that the previous proximal tibial osteotomy had no deleterious effect on the outcome of the subsequent total knee arthroplasty

ABSTRACT

Ogee-flanged socket was introduced by Sir John Charnley for use in low-friction hip arthroplasty. The results of 18 primary total hip arthroplasties performed in 17 patients with moderate congenital acetabular dysplasia were reviewed. Charnley total hip prosthesis including a non-modular femoral stem and an ogee-flanged acetabular socket were used in all patients. The average duration of follow up after arthroplasty was 5.3 years [range 4-7 years]. All patients were evaluated using a modified Harris hip scoring system and a standardized anteroposterior pelvis radiograph for hips. Differences between the preoperative and postoperative [last evaluation] scores were assessed with the student's t-test and Chi-square test. The mean overall modified Harris hip score was improved from 48 points preoperatively to 89 points at the last follow up evaluation, this improvement was significant. A low percentage of radiological demarcation at the bone-cement interface around the acetabular sockets was observed in the immediate postoperative and the last follow up radiographs

ABSTRACT

Ten femoral shaft fractures, with documented evidence of current and/or previous infection of the femur, were treated by interlocking femoral nailing as definitive surgery. Six cases had failed previous internal fixation [plating in two and Kuntcher nailing in four], four other cases had initial treatment by external fixation and pin tract infection was documented in all patients by bacteriological examination and culture. All cases had antibiotics according to culture and sensitivity tests for an average of 8.7 weeks. Three patients had minor wound healing problems and oozing, but neither local/systemic signs nor laboratory evidence suggesting deep infection was encountered postoperatively in any patient. All fractures united with an average time of 22.4 weeks. The results of the study showed that the use of interlocking nailing, in infected and previously infected femoral fractures, does not cause propagation of infection or more complications of bone infection, and retains all its advantages which make it the treatment of choice in femoral fractures
