RESUMO

Introduction: The diameter of the quadrupled Hamstring graft plays a significant role in the incidence of graft failures for ACL reconstruction. The ability to predict the graft size pre-operatively can prepare the surgeon for alternatives in the event of an inadequate graft diameter. Materials and methods: We retrospectively measured the diameter of the Semitendinosus tendon (ST) on the MRI in all patients who underwent arthroscopic ACL reconstruction using quadrupled Semitendinosus as their graft. We also estimated any correlation between various anthropometric data with pre-operative MRI based Cross Sectional Area (CSA) of the Hamstring tendon and final graft diameter in the South Asian population. The patients were included from Jan 2018 - Dec 2020. Results: The minimum CSA of ST to predict an eventual graft diameter of 7.5mm was 10.7mm2. The MRI based cross-sectional area measurement showed moderate correlation with the intra-operative graft diameter obtained. (r=0.62, p<0.001). The intra-class correlation coefficient between the radiologist and the surgeon was 0.82, 95% CI (0.57, 0.92) and a p-value <0.001. Conclusion: Pre-operative MRI can be a useful tool to predict the graft diameter. This coupled with the anthropometric data of the patient can be used as an adjunct to estimate the probable graft diameter. Thus, the surgeon can be better prepared for the surgery and can seek alternate graft options if the graft size is deemed inadequate pre-operatively.

RESUMO

INTRODUCTION: The management of talus bone loss in trauma is difficult and unsatisfactory. This study assessed whether the height of the ankle was preserved when entire or partial talar bone loss was managed with hind foot intramedullary nail augmented with autogenous rectangular or trapezoidal cortico-cancellous bone blocks from the iliac crest in the presence of active or latent infection. MATERIALS AND METHODS: Four patients were included in the study from January 2011 to December 2017. In the first stage, all four patients underwent debridement of the ankle, total or partial excision of the talus, and antibiotic-loaded bone cement spacer (ALBC) placement in the ankle joint. The second stage of the arthrodesis procedure was initiated six to eight weeks after the primary procedure, where these patients underwent arthrodesis with hindfoot nail and bone blocks from the iliac crest. RESULTS: All patients were followed-up for an average of 17.6 months (range 12.0 - 32.0 months). The arthrodesis site had united in all these four patients. The AOFAS scores were satisfactory in all patients. One patient underwent nail removal after the arthrodesis site had united. CONCLUSIONS: The hind foot nail with iliac crest bone block maintains the ankle height and ensures successful arthrodesis. In patients with partial/ complete bone loss with suspicion or confirmation of infection, staging the arthrodesis procedure minimises the chance of complications.

RESUMO

This is the first report of a long-term follow-up of an open bicondylar Hoffa with patella fracture. It is interesting to note the radiological changes of osteoarthritis 15 years after global intra-articular injury of the distal femur. The good clinical outcome is possibly due to the integrity of the knee ligaments and reconstruction of the extensor mechanism in addition to stable anatomical reduction and fixation.

RESUMO

Four men who presented with chronic dislocation of the radial head and nonunion or malunion of the ulna were reviewed after open reduction of the radial head and internal fixation of the ulna in attempted overcorrection. Their mean age was 37 years (28 to 46) and the mean interval between injury and reconstruction was nine months (4 to 18). The mean follow-up was 24 months (15 to 36). One patient who had undergone secondary excision of the radial head was also followed up for comparison. The three patients who had followed the treatment protocol had nearly normal flexion, extension and supination and only very occasional pain. All had considerable loss of pronation which did not affect patient satisfaction. Preservation of the radial head in chronic adult Monteggia fractures appears to be a promising mode of treatment.
