Computed tomographically guided biopsy of the spine.

STUDY DESIGN: Efficacy of the percutaneous biopsy of the spine under computed tomographic guidance was investigated. Seventy-five patients, ranging in age from 7 to 72 years, underwent this procedure. OBJECTIVES: To determine the usefulness of computed tomographically guided biopsies in the treatment of patients with spinal disorders. SUMMARY OF BACKGROUND DATA: The results of 68 biopsies (90.6%) were judged to be accurate insofar as the samples of tissue obtained could be diagnosed as specific types of neoplasm, infective lesions, reactive lesions of nonspecific type, or normal bone. METHODS: Biopsies that yielded a specific abnormality were categorized as true positives. The "normal" biopsies were followed for 6-18 months and were then deemed true negatives. Nondiagnostic ones were considered false negatives. RESULTS: The results are acceptable with an accuracy rate of 90.6%. It is a safe and simple procedure with a short learning curve. CONCLUSIONS: Computed tomographically guided biopsy of the spine is recommended as a procedure of choice, especially in cervical and thoracic lesions. Computed tomography is superior to fluoroscopy when dealing with small, deep-seated lesions especially in the cervical and thoracic regions and with lesions picked up on bone scan only, radiographs being negative. Needle biopsy under computed tomographic guidance is safe and precise.

Reconstruction of the quadriceps apparatus following open injuries to the knee joint using pedicled gastrocnemius musculotendinous unit as bridge graft.

The objectives of treating open knee joint injuries with disruption of the distal quadriceps mechanism are to ensure rapid wound healing and to restore joint function. For this it is necessary to provide soft tissue cover, control infection, restore full extension of the knee by reconstruction of the extensor apparatus and prevent joint stiffness by early mobilisation. Two cases are presented where the gastrocnemius (medial half) musculotendinous unit has been used to reconstruct, in one stage, the extensor apparatus and at the same time to provide soft tissue cover.

Single-stage reconstruction of soft-tissue defects including the Achilles tendon using the dorsalis pedis arterialized flap along with the extensor digitorum brevis as bridge graft.

Open ruptures of the Achilles tendon with loss of the tendon and the overlying skin are very difficult to treat. They pose the problems of (1) combating infection, (2) providing soft-tissue cover, and (3) bridging the gap in the tendon. They are generally managed as multi-staged procedures. Once the infection is brought under control with debridement and antibiotics, skin cover is provided by local transposition flaps, distant pedicle flaps, or free-tissue transfer with microvascular anastomoses. The tendon itself is repaired later by one of the conventional techniques. More recently, composite free-tissue transfers repairing the skin and tendon in a single stage have been reported. We describe a simple and very reliable procedure using a dorsalis pedis island flap which provides a vascularized, innervated musculotendinous unit (i.e., extensor digitorum brevis) to bridge the gap in the Achilles tendon and thin, mobile skin and fascia to close the defect in the skin. Two cases are presented, including the technical details, advantages, and limitations of this procedure.

Salmonellosis complicating aortic aneurysms.

We present our experience with two cases of salmonella infected aortic aneurysms. The treatment of salmonella infected aortic aneurysms has been associated with a high mortality, primarily due to the rapidity with which the post-infective complications of salmonellosis develop. Early diagnosis, adequate anti-microbial therapy and improved vascular surgical methods have resulted in a better prognosis for salmonella infected aortic aneurysms.

A bypass technique for aneurysms of descending aorta.

Uniformity of opinion does not exist regarding optimal surgical strategy for descending aortic aneurysms. We present a surgical technique for bypass during aortic cross clamp while operating on such aneurysms. Five patients have undergone surgery using this technique. All of them are alive, doing well with no complications.
