Correction Of Deformity

Mitchell J Thompson, Thomas S Roukis
One of the most severe complications in calcaneal fractures is a malunion. When a malunion occurs, subtalar bone block distraction arthrodesis provides restoration of calcaneal height, length, correction of varus deformity, and elimination of subtalar joint arthritis. A systematic review showed the union rate for all procedures was 95.78%. The overall complication rate was 38% for all procedures. This is the first study to categorically break down complications with statistical analysis. The data presented indicate the level of difficulty of the subtalar distraction bone block arthrodesis for calcaneal malunions and may even suggest the need for newer techniques...

Primary or secondary subtalar joint arthrodesis after displaced intra-articular calcaneal fractures makes use of talocalcaneal large-diameter screw fixation after an eventual correction of geometric hindfoot deformity. Despite this procedure usually having a successful functional outcome, potential complications occur, including nonunion and malalignment, with an unknown rate of loss of correction or implant migration during the healing period. Angular stable fixation of the subtalar joint arthrodesis with an interlocking nail applied in a minimally invasive technique affords maintenance of the hindfoot position until osseous healing occurs...

Neglected cervical spine trauma is rare with very few case series reported in literature. There are no clear guidelines for its treatment. If operative treatment is sought, the role of skull traction, type of approach (anterior only, posterior only, or combined), sequence of surgery, type of instrumentation, etc., have to be considered. Hence, the treatment is challenging. Autostabilization has been described in the natural history of degenerative lumbar spondylolisthesis. As a result, many patients are treated nonoperatively, obviating need of surgery...

The degree of freedom (DOF) and motion characteristics of a kind of compliant spherical joint were analyzed based on the screw theory, and a new design scheme for force-inversion of the compliant spherical joint was proposed in this paper. A novel type of six DOF compliant parallel mechanism (CPM) was designed based on this scheme to provide a large load capacity and achieve micrometer-level positioning accuracy. The compliance matrix of the new type of CPM was obtained through matrix transformation and was then decomposed into its generalized eigenvalues...

Paget's disease of bone is a chronic condition characterized by focal abnormalities of absorption and formation of bone, and it may lead to anatomical deformities, pain, fractures, and malignant transformation. It is common in the UK, Australia, New Zealand, and North America and has a strong hereditary component, affecting first- to third-degree relatives. The etiology remains unclear and treatment is based on control of the disease with bisphosphonates, with the aim of relieving symptoms and correcting laboratory abnormalities...
