Tibialis Posterior Tendon Transfer for the Management of Foot Drop.

The transfer of a normal tibialis posterior through the interosseous membrane to the dorsum of the foot can restore active ankle dorsiflexion where this has been lost from common peroneal injury, anterior compartment muscle loss, or in some neurological conditions. An appraisal of the indications, planning, and a step-by-step description is provided. How to cite this article: Eisenstein N, Fischer B, Nayagam S.

Prediction of distal tibial articular extension in tibial shaft fractures: both posterior malleolar fracture and non posterior malleolar fracture intra-articular extension.

BACKGROUND: Multiple authors have highlighted the increased incidence of occult posterior malleolar fractures (PMFs) with spiral tibial shaft fractures, although other reported associated risks of intra-articular extension have been limited. The aim of our study is to investigate both PMFs and non-PMFs intra-articular extensions associated with tibial diaphyseal fractures to try to determine any predictive factors. METHODS: We undertook a retrospective review of a prospectively collected database. The inclusion criteria for this study were any patient who had sustained a diaphyseal tibial fracture, who had undergone surgery during the study period and who had also undergone a CT scan in addition to plain radiographs. The study time period for this study was between 01/01/2013 and 9/11/2021. RESULTS: Out of 764 diaphyseal fractures identified, 442 met the inclusion criteria. A total of 107 patients had PMF extensions (24.21%), and a further 128 patients (28.96%) had intra-articular extensions that were not PMF's. On multivariate analysis, spiral tibial fracture subtypes of the AO/OTA classification (OR 4.18, p < 0.001) and medial direction of tibial spiral from proximal to distal (OR 4.38, p < 0.001) were both significantly associated with PMF. Regarding intra-articular fractures, multivariate analysis showed significant associations with non-spiral (OR 4.83, p < 0.001) and distal (OR 15.32, p < 0.001) tibial fractures and fibular fractures that were oblique (OR 2.01, p = 0.019) and at the same level as tibia fracture (OR 1.83, p = 0.045) or no fracture of the fibular (OR 7.02, p < 0.001). CONCLUSION: In our study, distal tibial articular extension occurs in almost half of tibial shaft fractures. There are very few fracture patterns that are not associated with some type of intra-articular extension, and therefore, a low threshold for preoperative CT should be maintained.

Reconstruction of Severe Ankle and Pilon Fracture Malunions.

Malunion of ankle and pilon fractures has significant detrimental effect on function and development of post-trauma osteoarthritis. Unfortunately, the incidence of malunion has been reported to be increasing. It is important to assess the ankle for congruency, because this determines the level where correction will occur. A plethora of techniques are available, with low-level evidence supporting each, and therefore it is important that the treating surgeon is fully prepared and comfortable in the techniques they are to use. Supplementary procedures are common and should be expected. This article provides a review of current methods of treatment and their outcomes.
