The Effect of Total Knee Replacement on Dual-Task Gait Performance in Older Adults.

Objective: Total knee replacement (TKR) is a common solution for patients with advanced knee osteoarthritis (OA). Still, fall rates remain relatively high after surgery. TKR may alter pain and knee function, balance control, and proprioception.

Successful reconstruction of natural femoral anteversion using a short femoral stem in total hip arthroplasty surgery.

Objective: Total hip arthroplasty (THA) involves postoperative risks, such as thigh pain, periprosthetic fractures, and stress yielding. Short, anatomical, metaphyseal-fitting, cementless femoral stems were developed to reduce these postoperative risks. This study aimed to examine the "MiniMAX" prosthesis, which is a new generation, short, anatomical femoral stem made by Medacta.

Renal cell carcinoma in a child presented as bilateral femur neck fractures caused by severe vitamin D deficiency.

An Ethiopian girl 14 years and 11 months of age presented with bilateral transcervical hip fractures. Workup revealed severe vitamins D and C deficiencies with secondary hyperparathyroidism. Imaging studies showed bilateral radiolucent metaphyseal bands with multiple lytic lesions in long bones.

Avulsion of the triceps tendon during acceleration stress.

The authors present a rare case of triceps tendon avulsion associated with +5 G-force and muscle straining. Although failure of musculoskeletal system, mainly the cervical spine, secondary to high-G exposure has been reported, this is the first report they have found of a triceps tendon avulsion. Furthermore, unlike other traumatic triceps avulsions reported, the pilot involved had no known predisposing factors.
