Biopsy of musculoskeletal tumors. Current concepts.

Biopsy is a key step in the diagnosis of bone and soft tissue tumors. An inadequately performed biopsy may fail to allow proper diagnosis, have a negative impact on survival, and ultimately necessitate an amputation to accomplish adequate margins of resection. Poorly performed biopsy remains a common finding in patients with musculoskeletal tumors who are referred to orthopaedic oncology centers. The principles by which an adequate and safe biopsy of musculoskeletal tumors should be planned and performed are reviewed, and the surgical approach to different anatomic locations is emphasized.

Efficacy of closed wound drainage after total joint arthroplasty. A prospective randomized study.

The efficacy of closed suction drains following joint arthroplasty operations was prospectively evaluated in a randomized manner. All 88 patients allotted to primary knee or hip arthroplasty operations during a 6-month period were included in the study. Drains were used in 32 of 58 patients following total knee arthroplasty and in 18 of 30 total hip arthroplasties. No statistical difference was found in the hemoglobin levels measured following surgery and in the number of patients requiring blood transfusions between the two groups after total hip arthroplasty (P = .06). The power of the test to detect a difference of 2 g% in hemoglobin levels is 94%. Two patients from each group had a transient serous discharge for 3 to 4 days following surgery and none had wound infections. Significantly more blood transfusions were needed in patients with drains following total knee arthroplasty compared with patients without drains (0.7 unit per patient versus 0.2 unit per patient, P = .005) to maintain the same hemoglobin blood levels. Patients with no drains had significantly more transient sterile serous wound discharge than patients with drains (38.4% vs 12.5%, P = .02). Superficial wound infection necessitating antimicrobial medication developed in one patient with drains and in no patients in the other group. These results suggest that drains may not be needed following total hip arthroplasty. The more common serous wound discharge may be of some concern when drains are not used following total knee arthroplasty.

Malignant bone and soft tissue tumors of the shoulder girdle. A retrospective analysis of 30 operated cases.

From 1988 to 1995, 30 patients (16 men) with malignant bone (n 23) and soft tissue (n 7) tumors of the shoulder girdle underwent surgery in our department. The mean age was 34 (6-80) years. 26 patients had primary and 4 had metastatic lesions. The average follow-up period was 3 (2-8) years, at the end of which 18 patients showed no evidence of disease, 2 were alive with disease, and 10 had died (9 because of tumor). 25 of the operations were limb-sparing procedures, while the other 5 were major amputations. Radical resection was performed in 4 patients, wide resection in 25 and marginal resection in 1. Local recurrence was observed in 2 patients. 10 patients with stage IIB tumors of the proximal humerus underwent extraarticular humeral and glenoid resection. Reconstruction was performed with either a modular or an improvised implant. Following surgery, those patients had a concave contour of the shoulder and poor abduction ability. Overall functional outcome was good in 18 patients, moderate in 11 and poor in 1. No correlation was found between functional outcome and reconstruction technique.
