Fractures at the lateral end of the clavicle inevitably require surgical treatment as there is high potential for delayed union or nonunion. Acromioclavicular dislocation also requires stable and solid fixation for healing, and surgical treatment is recommended for the maintenance of joint function. The hook plate maintains the biomechanics of the acromioclavicular joint, enabling early range of motion. Therefore, for the past 10 years, the hook plate has been widely used in distal clavicle fractures and acromioclavicular joint injuries. However, the hook plate is associated with several complications, such as proximal clavicle fractures, widening of the hook hole, rotator cuff tear, subacromial impingement, and often acromial fractures. We report on two unusual cases of acromion fracture after hook plate fixation in patients with distal clavicle fracture and acromioclavicular dislocation alongside a literature review.

OBJECTIVES: Cell adhesion molecules may play a role in integrating amnionic membrane. The objective of this study was to prove E-cadherin mRNA and proteins in cultured human amnionic cells. METHODS: We cultured amnionic cells from 4 women undergoing cesarean section without labor. E-cadherin was determined by immunohistochemistry and Western ligend blotting. To demonstrate E-cadherin mRNA, reverse transcription-polymerase chain reaction was performed. RESULTS: On immunohistochemistry, E-cadherin was abundantly showed on the cytoplasm of the cells. Western ligend blotting showed clear 120 kDa bands on four specimens, and relatively weak band on one specimen. Reverse transcription-polymerase chain reaction showed 432 BP bands. CONCLUSION: We proved E-cadherin and its mRNA by immunohistochemistry, Western ligend blotting and reverse transcription-polymerase chain reaction in cultured human amnionic cells.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

On the length, strength, free lateral motion, and perfect mobility of the thumb, depends the power of the human hand. The thumb is called pollex because of its strength and that strength is necessary to the power of the hand being equal to that of all the fingers."So stated Sir Chales Bell in the fourth Bridgewater Treatise, first published in 1833. Morrison and O'Brien advocated reconstruction of the thumb with a free wrap around flap from the big toe to recreate a stable, sensate and functional digit including the nail in 1980. From March, 1982 to July, 1988, Twelve thumb reconstructions were performed using the wrap around procedure at Hanyang University Hospital;12 successful thumb reconstructions were reviewed at an average of 16 months after surgery. There were several complications;these included skin necrosis(4), malunion(1), resorption of the bone graft(7). We considered that cosmesis and function were good;pinch grip averaged 68% of normal, sensibility returned in all patients as assessed by two-point discrimination(average 9.5mm). Over all the results are as follows. 1. The wrap around technic provides a good method of reconstruction. 2. The wrap around technic is one stage operation and can be used in the level of metacarpal amputation. 3. The surgeon should be familiar with microsurgical technic.
