The authors state: "While there are certainly controversies in the field of osteoporosis, there are also issues upon which there is complete or near-complete agreement: specifically, there is consensus that patients with hip fracture should receive pharmacological treatment to prevent additional fractures, as they are clearly at risk for recurrent hip or other osteoporotic fractures, and initiation of bisphosphonate therapy after hip fracture has been shown to reduce the risk of a second hip fracture".

A 48-year-old woman with a history of hypertension, rheumatoid arthritis treated with chronic prednisone, and a two-pack-per-week cigarette use, presented to clinic with 8 years of right knee pain. She had an intra-articular steroid injection with some relief 6 years ago. She denied any hip pain and uses a cane for ambulation. On physical examination she appears to be a healthy 52, 160-pound woman who walks with an antalgic gait. She has a 20 flexion contracture, with flexion limited to 90, and a mild valgus deformity of her knee. The extremity was neurovascularly intact and she had full, painless hip range of motion.

Canal-to-Diaphysis Ratio as an Osteoporosis-Related Risk Factor for Hip Fractures
Source:
Healio

Prevention of osteoporosis is essential to health, quality of life, and independence in the elderly. The accepted diagnostic method for evaluation of fracture risk after osteopenia and osteoporosis is the measurement of bone mineral density with dual-energy x-ray absorptiometry (DEXA). This method is limited because of its low accessibility, high capital costs, and low sensitivity. This study evaluated whether canal diameter is a reliable indicator as a major risk factor for hip fracture in the elderly.

Injectable gel encourages self-healing of cartilage

Knee injuries are the bane of athletes everywhere, from professionals and college stars to weekend warriors. Current surgical options for repairing damaged cartilage caused by knee injuries are costly, can have complications, and often are not very effective in the long run. Even after surgery, cartilage degeneration can progress leading to painful arthritis.

Getting the perfect fit for artificial hips

When a patient receives a new hip, it is usually adjusted only approximately to leg length. Greater accuracy requires a more precise measuring process as well as adjustable implants. Now, a new type of measurement method coupled with a modular implant should allow orthopedic surgeons to precisely calibrate leg length after the operation so it matches its original length.
