Objectives. The aim of the study was to investigate the results of patients with isolated length discrepancy between ulna and radius who underwent distraction osteogenesis with unilateral external fixator. Material and Methods. A patient with ulna shortening due to multiple enchondromatosis, a patient with ulna shortening due to ulnar club hand, and a patient with radial shortening due to radia...

A 13-year-old girl occasionally felt pain on the ulnar side of her right wrist before her right forearm abruptly locked in the pronated position while playing basketball. She had no pain or swelling after the injury; and after a month of therapy, she was seen at our hospital. On physical examination, the right forearm was locked in 70” pronation. When supination was attempted, the patient felt ...

Surgery for ulnar-sided wrist problems have proved a major challenge. A variety of bony procedures, which may or may not be supplemented with soft tissue interposition, tenodesis, and fusion of the distal radioulnar joint, have been designed in an attempt to address this challenge. The problems encountered in the use of these procedures have included weakness, snapping and instability of the di...

Giant cell tumour of the bone (GCT) is a rare locally aggressive primary bone tumour with an incidence of 3% to 5% of all primary bone tumours. The most common location for this tumour is the long bone metaepiphysis especially of the distal femur, proximal tibia, distal radius, and the proximal humerus. Involvement of distal ulna is rare accounting for 0.45% to 3.2%. Considering local aggressiv...

OBJECTIVES To examine the associations between absolute and relative handgrip strength (HGS) and physical performance. METHODS A total of 135 old men aged 70-89 years had muscle thickness (MT) measured by ultrasound at anterior forearm (MT-ulna). Maximum voluntary HGS was measured for the dominant hand. Relative HGS was calculated as ratios of HGS to MT-ulna (HGS/MT-ulna, kg/cm), HGS to forea...

We describe a new technique of pedicle freezing of the distal radius with malignant bone tumour and osteotomy of the normal ulna. The distal radius was sufficiently elevated to enable freezing without damaging adjacent tissues by releasing the distal radio-ulnar and radio-carpal joint and cutting the middle third of the ulna. The distal radius (including the tumour) was soaked in liquid nitroge...

INTRODUCTION Stature estimation from the skeletal remains bears immense importance in the forensic sciences. Along with the conventionally used long bones, the humerus, femur, tibia, etc.; the ulna also has been used for the said purpose since 1952. Though studies which had highlighted the stature estimation in Bengalee males were carried on earlier, in females, this has still not been uncovere...

BACKGROUND We aimed to determine specific formulae by which we are able to estimate the body stature from the length of ulna and tibia calculated from the X-rays in order to be a reference for skeletal remains-based identification in Iranian population. METHODS The length of right ulna and tibia of 49 male and 52 female adults, who were anatomically healthy, were measured on the antero-poster...

BACKGROUND Intramedullary screw (IMS) fixation was wildly used in fifth metatarsal base fractures (FMBFs) and the results were satisfactory. However, in the comminuted osteoporosis or small displaced avulsion FMBFs, anatomical reduction and stable fixation could not be achieved with IMS. The Locking Compression Plate (LCP) distal ulna hook plate fixation was a novel alternative fixation method....

Proximal ulna fractures can be difficult to manage because of the elbow's complex anatomy. Advances in understanding elbow anatomy and biomechanics, however, have led to new insights. Careful preoperative evaluation is critical because failure to restore normal anatomy of the proximal ulna could have a detrimental effect on postoperative elbow function. Management options include anatomic plate...
