Operative treatment modalities for calcaneal fracture are still controversial. The outcome of intra-articular calcaneal fracture is mainly influenced by the soft tissue and the subtalar joint. Percutaneous method of internal fixation has been attempted to avoid the problems. ⋯ Twenty-two patients with 26 calcaneal fractures were included. After a mean follow-up of 2 1/2 years and with American Orthopaedic Foot and Ankle Society hind foot score 82 points out of 100. Percutaneous fixation of calcaneum fracture is good alternative method in types IIA, IIB and IIC and selective type III fractures.

Seven cases of intercondylar fractures of the distal humerus were treated by a mini-external fixation technique. The average range of motion was 30 degrees to 110 degrees. ⋯ Open wound sites healed in 6 cases. There were no evidence of any nerve palsies.

The instant axis of rotation (IAR) is an important kinematic property to characterise of lumbar spine motion. The goal of this biomechanical study on cadaver lumbar spine was to determine the excursion of the IAR for flexion (FE), lateral bending (LB) and axial rotation (AR) motion at L4-5 segment. Ten cadaver lumbar spine specimens were tested in a 6 degrees-of-freedom spine tester with continuous clyclical loading using pure moment and follower pre-load, to produce physiological motion. ⋯ The IAR excursion was faster and larger during neutral zone motion in FE and LB, but uniform for AR motion. This is the first published data on the continuous excursion of IAR of a lumbar motion segment. The methodology is accurate and precise, but not practicable for in vivo testing.
