Biomechanical study of dynamic changes in L4-L5 foramen surface area in flexion and extension after implantation of four interspinous process devices.
Lumbar spinal stenosis is a major public health issue. Interspinous devices implanted using minimally invasive techniques may constitute an alternative to the reference standard of bony decompression with or without intervertebral fusion. However, their indications remain unclear, due to a paucity of clinical and biomechanical data. Our objective was to evaluate the effects of four interspinous process devices implanted at L4-L5 on the intervertebral foramen surface areas at the treated and adjacent levels, in flexion and in extension. ⋯ Level IV. Investigating an orthopaedic device.

Clinically relevant heterotopic ossification after elbow fracture surgery: a risk factors study.
Heterotopic ossification (HO) is a common complication of elbow fracture surgery that can significantly impair function and range of motion (ROM). Whereas numerous studies have assessed HO after hip trauma or replacement surgery, few data have been reported on the prevalence and risk factors of HO after elbow fractures. ⋯ Level IV, retrospective study.

Minimally invasive posterior approach in the popliteal fossa for semitendinosus and gracilis tendon harvesting: an anatomic study.
Harvesting the semitendinosus (ST) and gracilis (GR) tendons at the anteromedial side of the knee may be hampered by a conjoint tendon insertion on the tibial metaphysis and an accessory bundle between the ST and the medial gastrocnemius. Locating and sparing the terminal branches of the saphenous nerve are difficult on an anteromedial approach. The principal objective of the present anatomic study was to assess the feasibility of ST and GR harvesting from a minimally invasive posterior approach in the popliteal fossa. The secondary objective was to analyze the risk of saphenous nerve branch lesion during harvesting. ⋯ Level 4.
