Successfully treatment of acute shoulder arthroplasty infections strongly depends on the timing of treatment. The objective of this study is to determine the normalization curve of C-reactive protein (CRP) after shoulder arthroplasty

Prospective study including 63 patients undergoing shoulder arthroplasty (46 reverse shoulder arthroplasty (RSA) and 17 total shoulder (TSA)). Mean age 74.1 years old. 25 cuff deficient shoulders, 14 acute fractures, 19 primary gleno-humeral arthritis and 5 fracture sequel were included. Blood samples to determine CRP were obtained before surgery the day of surgery, 24 and 48 hours after surgery and then 6, 8 and 14 days after surgery (data of blood samples was determined based on a previous limited study). Co-morbidities that could interfere CRP were also recorded

Normal value of CRP before surgery (mean 1.28) slightly increases 24 hours after surgery (mean 3.92), reach maximum value at 48 hours after surgery (mean 6.91) and then slowly decreases to normalize at 14 days (6th day mean 3.80, 8th day 2.33 and 14th day 1.08). Normalization curve is not affected by age, diagnosis or type of arthroplasty

CRP after shoulder arthroplasty reaches maximum value at 48h and then slowly decreases to become normal at 14 days. Any deviation from this normalization curve may help in diagnosis and early treatment of acute shoulder arthroplasty infections

Introduction: Congenital kyphosis is an uncommon deformity caused by failure of the vertebral bodies to form and/or segment. It is treated surgically. Our purpose is to confirm whether the treatment protocols established years ago are still valid and to assess the benefits of improved implants.

Materials and methods: Between 1985 and 2003, 24 patients underwent surgery in La Paz Hospital. They were classified into three groups: < 5 years (8 p), 6–12 (6 p) and > 13 (10 p). The minimum follow-up was 2 years (2–14). The procedures were posterior or circumferential spinal fusion, with or without instrumentation, and corrective osteotomy. Complications were evaluated radiographically.

Results: In the first group posterior spinal fusion was performed in six patients and circumferential in two, with a correction rate of 55%. In the second group instrumented circumferential spinal fusion was performed in three cases and instrumented posterior in three (30% correction). In the third group eight of the ten patients underwent instrumented anteroposterior spinal fusion (osteotomy in five) and the correction rate was 45%. Complications: 3 pseudoarthrosis, 1 DVT, 2 infections and 3 failed implants.

Conclusions: Congenital kyphosis can be controlled at any age, although early surgery is best. Gradual correction occurs after poster spinal fusion in children and instrumentation prevents revision of the fusion and prolonged immobilisation. Persons over the age of 5 with type I kyphosis usually require circumferential spinal fusion.

Introduction: Synovial sarcoma ranks as the fourth most common sarcoma, but it is uncommon in the hand. Most Synovial Sarcomas arise in para-articular soft tissue such as tendon, tendon sheath and bursa adjacent to the large joints capsules. Arround 60–70% of these tumors involve lower extremity and they frequently affect knee, thigh and foot. The reported incidence for Synovial Sarcoma in hand is only 8.5%.

Material and methods: We carried out a retrospective study of 6 hand and forearm sarcomas, of a series of 35 synovial sarcomas surgically treated in our center from 1991 to 1997, with a 6 years follow up (3y.–11y.). 3 patients were male and 3 female, with a mean age of 54 years at the moment of initial diagnosis. Histologically all of them were synovial sarcomas: 4 monophasic and 2 biphasic. The inmunochemistry showed that the neoplasic cells were positive for vimentin, epithelial membrane antigen and cytokeratin. 2 of them were localized in the palmar aspect of the hand (2 ulnar cases and 2 eminence tenar cases), an 2 cases were dorsal. 2 cases were misdiagnosed as benign lesions and treated with tumor excision at another center.

Results: Primary treatment consisted of radical local excision of synovial sarcoma of the hand. 5 patients received adjuvant chemotherapy with CYVADIC and radiotherapy. 2 cases of recurrence received a second surgical treatment with forearm amputation. The mean time to recurrence was 12 months. At the end of the follow-up 3 patients developed metastatic disease and 2 of them died.

Discussion: Synovial Sarcoma in hand is a highly malignant tumor; due to its morphology they can be misdiagnosed as benign lesions such as aggressive fibromatosis or ganglion cysts. If we diagnose a soft tissue tumor in hand we must practice complementary tests to achieve early diagnosis. It is also important the multidisciplinary treatment of Synovial Sarcoma.
