The occurence of digit like structures around vertebral column is a rare and only one case in the cervical region has been reported before. Here we report three more cases of cervical digits with computed tomography and magnetic resonance imaging correlations as the first cases of the literature.

Test-retest reliability of the stair test in patients with total hip arthroplasty.

Purpose: Stair climbing is one of the important functional activities of daily living to maintain mobility and independence. Walking and stair climbing have been identified by clinicians and patients as critical functional activities before and after total hip arthroplasty (THA). Testing the ability to manage steps has been commonly used in clinical and research settings because it is an inexpensive and simple way to measure functional status after THA.

Avascular necrosis of the distal pole of the scaphoid.

Avascular necrosis (AVN) of the scaphoid predominantly occurs in the proximal pole. Review of the literature revealed only six cases and all are suspect due to the lack of either MRI investigation or investigation of bleeding preoperatively. We report four new cases and one of them appears to be a real distal pole AVN of the scaphoid in the literature.

Spontaneous regeneration of the large femoral defect in patient with diffuse osteomyelitis after intramedullary nailing.

Infection of the long bones after intramedullary nailing is a troublesome condition and management of the infection remains challenging to orthopedic surgeons. Associated infection can be more problematic and more diffuse in intramedullary bone fixation, since it may spread along the nail. Surgical treatment choices are also difficult especially in cases with large bone defects after debridement.
