Radiologic Changes by Early Motion in Neck Fractures of the Fifth Metacarpal Treated with Antegrade Intramedullary Fixation.
As intramedullary (IM) fixation is one of the fixation methods used in neck fractures of the fifth metacarpal, an early motion of injured finger can be allowed. The purpose of this study is to evaluate whether immediate active motion affects the stability of antegrade IM fixation in surgical treatment of neck fractures of the fifth metacarpal bone and to assess related factors. ⋯ The change of 5th metacarpal length and tip to head distance of K-wire can occur by an early mobilization in the antegrade IM fixation for neck fractures of the fifth metacarpal. However, we thought that an early active motion after surgery is important to increase the patients' satisfaction, even though careful selection of candidates is necessary.

Intramedullary Nail Fixation for Displaced and Unstable Distal Radial Fractures in Patients Aged 65 Years or Older.
Distal radius fractures in elderly patients are now commonly treated with a volar locking plate, but flexor pollicis longus dysfunction caused by stripping of the muscle and tendon irritation and rupture caused by prominence of the implant have been reported. Intramedullary implants can stabilize distal radius fractures while minimally affecting the flexor and extensor tendons and muscles around the site, but osteoporosis in elderly patients might affect the radiographic and functional results of distal radius fractures treated by intramedullary implants. We investigated the radiographic and functional results of intramedullary implants for distal radius fractures in patients ≥65 years of age. ⋯ The findings of this study indicate that intramedullary implants for dorsally displaced extra-articular or simple intraarticular distal radius fractures may offer good radiological and functional outcomes without hardware irritation in elderly patients. Distal radius fractures with an osteoporotic, large medullary canal should be stabilized by implants of an appropriate size.

The Anatomical Relationship Between the Dorsal Cutaneous Branch of the Ulnar Nerve and the Ulnar Styloid Process with Variations in Forearm Position.
There are significant variations in the anatomy of the dorsal cutaneous branch of the ulnar nerve (DCBUN). The DCBUN is at risk for iatrogenic injury during surgeries around the ulnar side of the wrist. The purpose of this study was to demonstrate the relationship between the ulnar styloid process and the DCBUN and to confirm the DCBUN's change in location with different forearm positions. ⋯ We recommend making a skin incision on the ulnar side around the styloid process with the forearm in supination or neutral position was another method to avoid injury of DCBUN.
