Pinpoint accuracy: guided core biopsy diagnostic accuracy in musculoskeletal lesions.

Background: Core biopsy is integral in the work-up of diagnosis for musculoskeletal lesions. Prior to referral through Christchurch hospital-a tertiary referral centre for sarcomas/musculoskeletal lesions, many patients undertake guided core biopsy in peripheral hospitals. We wished to assess the accuracy of these biopsies undertaken in the peripheral centres and compare to those done in the tertiary setting.

A Comparative Outcome Study of Hamstring Versus Tibialis Anterior and Synthetic Grafts for Deltoid to Triceps Transfers.

Purpose: To assess elbow extension strength and complications after deltoid-triceps transfers using hamstring tendon graft compared with tibialis anterior and synthetic tendon grafts.

Methods: A retrospective review of deltoid-triceps transfers in patients with tetraplegia performed between 1983 and 2014.

Results: Seventy-five people (136 arms) had surgery performed, with the majority undergoing simultaneous bilateral surgery (n = 61; 81%).

Outcome after pelvic sarcoma resection reconstructed with saddle prosthesis.

Unlabelled: We retrospectively reviewed 27 patients who had saddle prosthetic reconstruction for pelvic sarcoma from 1991 to 2001 with a mean followup of 45 months. Functional outcome was assessed with Musculoskeletal Tumor Society Scores of 1987 and 1993 and the Toronto Extremity Salvage score. Survival, recurrences, and complications were recorded.

Outcome in two groups of patients with allograft-prosthetic reconstruction of pelvic tumor defects.

Unlabelled: To predict the outcomes obtained with allograft-implant composite reconstruction of pelvic defects after bone tumor resection better, a retrospective review of a prospectively collected database was done and two groups of patients were identified. These groups were compared with respect to oncologic and functional outcomes in this investigation. Group 1 included 21 patients with allograft total hip replacement reconstruction for pelvic bone tumors that required Type I and II or Type I, II, and III pelvic resections.

Iliosacral resection for primary bone tumors: is pelvic reconstruction necessary?

Unlabelled: Iliosacral resection for primary bone tumors creates a large unstable pelvic ring defect, the treatment of which remains controversial. We did this study to determine if skeletal reconstruction of such defects is necessary. Sixteen patients whose data were collected prospectively had iliosacral resection with a minimum followup of 12 months.

Interfragmentary compression across a simulated scaphoid fracture--analysis of 3 screws.

Purpose: To measure the interfragmentary compression generated across a simulated fracture in cadaveric scaphoids by 3 different headless compression screws.

Methods: A transverse osteotomy was made through the waist of each scaphoid and a load cell to measure compression was interposed between the fragments, which were then fixed internally retrograde with either an Acutrak Standard (n = 10), Acutrak Mini (n = 12), or Bold (n = 10) screw. The surgeon was blinded to the measured compression, which was recorded during screw insertion and for the following 5 minutes.
