We report our retrospective multicentre experience of managing periprosthetic knee fractures using locking plates, cemented nails and distal femoral prosthesis. The Aim of this study is to analyze the practicality of management of these injuries using modern methods of fixation or salvation. 62 patients presented to 3 centres between 2003 and 2010. After implementation of inclusion criteria, clinical, radiological and functional outcomes were evaluated in 54 patients, with a minimum follow-up of 6 months. 34 patients were treated with locking plates (10 males, 24 female; mean age 76), 16 with cemented/locking nails (4 males, 12 females; mean age 84.5), and 4 with distal femoral replacement prosthesis (2 males, 2 females; mean age 79). Locking plates which were used with a minimally invasive pattern produced the best outcomes in our study. A statistical significance of p value of less than 0.01 was found in union time between patients operated on with an open technique (6.69±2.69 months) and those operated on with a minimally invasive technique (3.6±0.91 months). Nailing with augmented cement is a useful technique in patients who are not suitable for challenging surgery & rehabilitation programmes. There was a significant difference in mean time to functional weight bearing (p< 0.01) between the plate group (4.79±2.6 months) and the nail group (2.63±0.5 months). Post-operative range of motion was also better for nails (106.36±14.33O flexion) compared to plates (93.24±26.8O), a result that approached significance (p=0.065). We recommend minimal invasive plating in uncompromised physiological conditions, as an ideal method of fracture fixation in view of statistically significant union rates. Cemented nailing is recommended in patients where early rehabilitation is essential. Distal Femoral prosthesis replacement is a useful salvage method.
To report the difference in the rates of avascular necrosis (AVN) of the femoral head following change in the hip abduction angle in the hip spica. Up until 2002, following closed and medial open reduction of the dislocated hip, the joint was immobilised in a 90° of flexion, 60° of abduction and 10-20° of internal rotation hip spica. The practice was changed after 2002 to 45° of hip abduction in the spica with other parameters remaining same. We audited the rates of radiologic AVN in these two groups of children. Group A, before 2002, had 20 children and in group B, after 2002 till Aug 2007, had 53 children. AVN was quantified on 2 year radiograph by the classification described by Salter and noted its progression on serial radiographs.Purpose of the study
Methods
We describe a new technique of talar dome osteotomy in the treatment of fixed equinovalgus deformity of the foot in patients with Fibular Hemimelia and successfully applied it in two patients. Fibular Hemimelia is a congenital absence or hypoplasia of fibula with associated fixed equinovalgus deformity of the foot. Treatment for this deformity ranges from corrective osteotomy of the tibia, calcaneum to Syme's amputation.Purpose of the study
Background
A recent meta-analysis for total knee replacement (TKR) undertaken with navigation demonstrated improved accuracy of implant positioning but did not have sufficient evidence on functional outcomes. This meta-analysis evaluates the functional outcomes for TKR with and without navigation. We present a randomized prospective and comparative studies on functional outcomes of TKR with and without navigation were identified. The selected articles were tested for publication bias and heterogeneity. Studies presenting the functional outcomes in terms of knee society score, oxford knee score and HSS scores were included in the study. The data was then aggregated by random-effects modelling after which estimated weighted mean differences for individual functional scores were calculated. Sixty two studies were identified and reviewed independently by two researchers; ten studies fulfilled the inclusion criteria, resulting in 976 cases for the meta-analysis (490 with navigation and 486 without). The mean age of both groups was similar (68 and 69). Results of a meta-analysis are best demonstrated by funnel graphs, forest plot, P values, and confidence intervals. In summary, the weighted mean of difference of KSS score is −0.288, with a p value of 0.867. Moreover, the standard means of difference of Oxford knee score was 0.133, with a P value of 0.257. The HSS scores resulted in a SMD of −0.099 and a ‘p’ value of 0.686. Finally, the range of motion weighted means of difference was 1.428, and a ‘p’ value of 0.228. This meta-analysis demonstrated that there is no statistical advantage to the use of navigation for TKR in terms of functional outcome; the increased positional accuracy does not impart an improved outcome as has been proposed. This is probably due to the tolerances available in the implant positioning. This meta-analysis is providing the early outcomes &
highlighting the necessity of long term studies.
Currently, the optimal treatment of pipkin fractures remains controversial. To rovide guidance on the management of these challenging injuries, we systematically viewed the available literature on outcomes following presentation with pipkin fracture dislocations and meta analysis was applied where applicable.
In type II, III &
IV cases, no statistically significant advantage is noticed in this respect. Overall incidence of AVN is 11%, highest incidence is reported in type III fractures.Highest incidence of Heterotopic ossification is reported in anterior or anterolateral approaches. Incidence of nerve injury in Pipkin fractures reported as 13%.
Incidence of poor results increases from type I to type IV cases. Statistically no significant difference is added on to anterior or posterior approaches or timing of reduction within or after six hours in the management of these fractures based on TE results. This meta analysis proving type of fracture is the most important prognostic factor influencing the outcome.
The purpose of our study was to determine the medium term clinical and radiological outcome of comminuted, displaced fractures of the distal radius. We present our experience in using the Aculoc (Acumed) volar fixed angle plate to treat 100 consecutive fractures of the distal radius.
The aim of the paper is to provide an independent single surgeon experience with BHR after a seven-year follow-up. A cohort of 117 hips in 101 consecutive patients operated by the senior author between Jan 1998 and Dec 2002 were assessed to note their clinical, radiological and functional outcome after a mean follow-up of 7 years (5–9.4 years). Primary osteoarthritis was seen in 73 hips and secondary in 44 hips. Their mean age at surgery was 54 years (range 20–74years). At latest follow-up their mean flexion was 100°and their mean functional outcome scores were respectively: Oxford hip score of 21.5 (12–52, mode 12); Harris hip score of 84.8 (25–100, mode 97), Charnley modification of Merle d’ Aubigné and Postel scores were 4.8 for pain, 4.3 for walking and 5.4 for movement; and SF-36 (physical component 43.9 and mental component 51.45). Failure in the study was defined as revision for any reason. Revision was undertaken in 8 hips (6.8%), five within the first year for periprosthetic fracture neck of femur and 3 hips after the end of 5-year follow-up (2 for advance collapse of the femoral component in patients’ with avascular necrosis of the femoral head and 1 hip for sepsis). The Kaplan-Meier survival with revision as end point at minimum 5-years of follow-up was 95.7% (95% CI 92–99%) and overall survival at an average 7-years was 91.7% (95% CI 86–97.6%). All the failures were due to the femoral component. However, the reported survival with the use of traditional uncemented and cemented femoral stems is beyond 99% at similar period of follow-up. Patient selection particularly in patients with secondary osteoarthritis is therefore a critical factor when choosing BHR components.
The clinical outcome was measured using Harris, Charnley, Oxford hip scores and quality of life using SF-36. Radiographs were systematically analysed for implant position, fixation, and loosening.
The clinical scores were respectively, Harris 85 (25–100), Oxford 21.5 (12–52), mean Charnley score 4.8 for pain, 5.3 for movement and 4.3 for mobility; the mean SF-36 score were 44 (12–58) for the physical and 51.4 (19–71) for the mental component. With an end point of definite or probable aseptic loosening, the probability of survival at 5 years was 100% and 97.3% (95% CI = 2.9) for acetabular and femoral components respectively. Overall survival at 5years with removal or repeat revision of either component for any reason as the end point was 91% (95% CI: 82 to 97%).
In the studies using SF36, the mean Physical Component Summary (PCS) for the amputation group was 39.76 +/−7.06 and mean Mental Component Summary (MCS) was 52.05+/−3.39. The mean PCS for the reconstruction group was 38.5+/−0.78 and the mean MCS was 50.76 +/− 3.09. The mean physical SIP score for amputation was 13.033 with SEM of 3.048, and the psychological SIP score was 15.953 with SEM of 1.153. The mean Physical SIP for reconstruction was 10.686 with SEM of 1.034 and the psychological SIP was 10.754 with SEM of 0.647. The Unpaired t test was used to compare the outcomes of amputation and reconstruction, studies using SF36 and SIP scores were compared independently. Our results show that physical morbidity in both groups is not significantly influenced by the modality of surgical intervention, but there is a statistically significant difference noted in psychological morbidity, the group with reconstruction being better. These results were consistent in studies using either of the two generic scales namely, SF36 or SIP scores.
