Modified acromioplasty for shoulder impingement syndrome with an intact rotator cuff

The study included 20 consecutive patients [14 males and 6 females] with an average age of 6.4 years. The dominant extremity was involved in 17 patients. The follow-up period was 20 months. Before operation, all the patients had shoulder pain for at least one year despite conservative treatment. At operation, the rotator cuff tendons were explored and were intact. The modified two-step acromioplasty followed by proper rehabilitation was successful in 90% of patients. It was believed that removal of only the inferior prominence is insufficient and may lead to continuing or recurring of symptoms and that the removal of the anterior portion is advised as it continues to irritate the subacromial bursa and the rotator cuff

Reconstruction of the deficient femur by impaction - grafting in revision hip arthroplasty Apreliminary report of twenty patients

Impaction bone-grafting was performed using compressed morselized cancellous allograft and a cemented collarless polished double tapered Exeter stem in twenty revision total hip arthroplasties that were done because of aseptic loosening. The average follow-up duration was 26 months [range 13 to 30 months]. The average age at the time of the revision was 58.4 years [range 38 to 72 years]. There were 15 men and 5 women. The operation was the initial revision in 19 patients [95%] and re-revision in one patient [5%]. The postoperative Harris hip score was 89 points [range 60-96 points] and 75% of the patients were pain-free. On radiograph, subsidence was common [12 patients, 60%] and averaged 2.5mm [range 1- 6mm], however, although the study group was relatively small, the overall score may not accurately reflect the rate or amount of subsidence. On the other hand, migration of the cement mantle within the allograft reconstruction was evident in two patients only [10%], non-progressive with an average sunk of 1.5mm. Lucent lines were rare, and in 90% of the revisions the radiographs showed evidence of graft incorporation and bone remodeling. Intra-operative complications included two patients [10%] with fracture of the femur during impaction and were managed by insertion of circlage wires. Early complications included one case [5%] of superficial wound infection, DVT, and heterotopic ossification. Late complications included one case [5%] of graft resorption with no evident incorporation after one year. Further study is necessary, but these preliminary findings are encouraging and we believe that this is a reliable method for femoral revision, reconstruction, and reconstitution

Synthesis and anti-inflammatory activity of some thieno [2,3-d] pyrimidinone derivatives

3-amino-2,5,6-trimethylthieno [2,3-d]-pyrimidin-4[3H]-one [1] was reacted with anhydrides, isatins, isothiocyanates and isocyanates to obtain the pyrimidinone derivatives 2, 3 and 4, respectively. Cyclization of 3-N'-substituted-thioureas 4 with chloroacetyl chloride, substituted phenacyl bromides and malonic acid furnished thiazolidinones 5, thiazolines 6 and thioxopynmidin-4,6-dione 7, respectively. Representative members of these compounds were evaluated for their anti-inflammatory activity. It has been reported that some thieno [2,3-d] pyrimidinone derivatives exhibit anti- inflammatory activity. In addition, certain thiourea, thiazolidinone and thiazoline derivatives are well known as biological agents including anti-inflammatory action
