Winging of the scapula is characterized clinically by a prominence of the vertebral border and inferior angle of the scapula. Trauma, neuritis, neural injury during surgical procedure and many other causes may develop winging of scapula. When pain and functional impairment persist, surgical intervention may become appropriate. We report two cases of winged scapula. One case was serratus anterior palsy due to blunt trauma, which was treated by transfer of teres major and pectoralis minor elongated with a tensor fascia strip. Another case was trapezius muscle palsy due to iatrogenic spinal accessary nerve injury, which was treated by transfer of the levator scapulae, rhomboid major and rhomboid minor muscle. In the former case, there was no weakness nor deformity of affected shoulder. In the later case, there was some residual pain and limitation of motion.

Locking of the metacarpophalangeal(MP) joint of thumb in mild hyperextension is relatively uncommon problem. The most frequently recognized cause appears that proximal palmar ligament or volar plate were ruptured tranversely with its distal part riding over the volar prominence of the radial condyle of the first metacarpal head. We experienced two cases of locking of the MP joint of the thumb due to volar plate injury. Closed reduction was failed in both cases and open reduction was done by cutting the constricted ligament hundle over the radial condyle of the first metacarpal head. Our description of this mechanism is supported by expeimental evidence that we obtained from the cadeveric specimens. The height of radial side condyle of first metacarpal head is higher than ulna side of that by 1.76mm in both hands of 16 cadeveric specimen. So we are going to report these cases with a review of the literature, and suggest that the preferable location of surgical incision in open reduction is radial side of metacarpal head.

Although flexion and extension lateral views were known the most preferable diagnostic method of instability of lumbar spine, many authors had reported that there were some findings which suggested instability of lumbar spine in plain films. This study was undertaken to analyze clinical aspect and plain film findings of dynamic instability of lumbar spine and to suggest indication of dynamic X-ray to find out the causes of low back pain. A retrospective analsysis was perfomed on 30 patients who had dynamic instability of lumbar spine without spondylolithesis between January 1996 and March 1997. They were reviewed in sex, age, symptom duration and instability level, etiologic factor etc. And then their plain films and flexion and extension lateral views were reviewed. Following results were obtained. Dynamic instability was more frequent in women than in man and occured younger age in women. The mean symptom duration was 5 years and 10 months and simple degenerative change was the most common etiologic factor. In plain films, traction spur and dome shaped end plate were common findings and the L4-5 intervertebral disc space was most frequently involved(23/30 cases). Translation was occured more frequently in flexion position(23/30 cases). The mean dynamic translation distance was 4.7mm, the mean sagittal rotational angle was 16.2degreesand the mean angular displacement was 3.2degrees. Conclusively, among the diagnostic criteria af instability of lumbar spine, translational distance was the most common finding. Flexion and extension lateral views have diagnostic value in patients who complaint back pain from unknown origin, in old age, for prolonged symptom duration, or those who have findings associated with instability in plain films.

A case report on the ABO-type imcompatible transfusion has been made. The case was O-type, 51 year old male who has been transfused 1,000ml of A-type whole blood during and after the intramedullary nailing of the left femur. He had fall in acute hemoglobinuric renal failure immediately after the transfusion. He has been received peritoneal dialysis (P.D.) at eighth day after mismatched transfusion, to correct the uremic condition. His pre-P.D. labaratory findings were Hb. 4.5gm%, BUN 85mg%, creatinine 12. 2mg% and K 7.0mEq/1. He was well recovering after the P.D. but worse again in 16th day after mismatched transfusion with BUN 114mg%, creatinine 12.4mg% and pulmonary edema. An-other P.D. was performed at 16th day and recovered gradually since then. He had marked maximum amount of urine was 9, 100ml at 36 th day after mismatch transfusion. Following the second P.D. his conditions improved gradually and electrolyte imbalance was controlled caused from polyuric state properly. His renal condition was recovered completely at the ten weeks after the mismatch transfusion.
