Leg injuries.

Injuries in the leg span a broad spectrum of patient age and athletic level. Overuse injuries, such as medial tibial stress syndromes and stress fractures, tend to occur in the young athlete, whereas tennis leg usually occurs in the older population. With a few exceptions, most of these injuries can be successfully treated nonoperatively. Particularly with the young athlete, it is important to stress the necessity to rest and avoid activities that would compound the injury.

A comparison of reamed and unreamed nailing of the tibia.

The availability of unreamed interlocked nails for fixation of tibia fractures has raised the issue of what effect reaming the intramedullary canal has on the clinical outcome after tibial nailing. A retrospective review was performed of all tibial fractures treated with interlocking nailing at the authors' institution over the past 5 years in order to compare reamed and unreamed nailing. Forty-five nailings were identified of which 38 had adequate follow-up information to be considered healed or non-united at 1 year. Thirteen reamed and 23 unreamed tibial nailings were followed to healing; there were 6 nonunions. The unreamed nailings had lower average operative times and lower average estimated blood loss, although the results did not reach statistically significant levels. There was a statistically significant difference in healing times, with unreamed nailings taking an average of 242 days to heal while reamed nailings took 158. This difference held for subgroups such as isolated tibia fractures, closed tibial fractures, and high-energy tibial fractures. Six non-unions occurred, one in a reamed nailing and five in unreamed nailings. Malunions occurred in four reamed nailings and six unreamed nailings, most often in distal third fractures, interlocked on only one side of the fracture. Patellofemoral complications were more common in unreamed nailings. Although this study is limited by retrospective, nonrandom design, it raises questions about the routine use of unreamed nailing with regard to healing potential and other postoperative complications. Further study is warranted.

Osteochondroma of the scapula.

Osteochondromas are common primary bone tumors which are usually located in the distal femur. In a large retrospective study from the Mayo clinic, osteochondromas comprised 36% of benign bone tumors and nearly 10% of all bone tumors. While the scapula is rarely involved, this is the most common tumor of the scapula. Clinical signs of this lesion include shoulder pain and limited range of motion. Patients may present with winging of the scapula. Computed tomography is often necessary to fully define the location and character of the lesion. We present the case of a 14-year-old girl with pain and limited range of motion of the left shoulder. The diagnosis was that of osteochondroma of the scapula.

Current trends in the diagnosis and treatment of hepatic artery aneurysms.

Aneurysms of the hepatic artery are rare lesions that constitute 20% of all splanchnic artery aneurysms. Their well-documented natural history includes progressive enlargement and eventual rupture. Computerized tomography, abdominal ultrasonography, or MRI may be used for initial evaluation, but angiography is required to make the definitive diagnosis and for delineation of the vascular anatomy. The lesion should be corrected surgically after the diagnosis is confirmed. Lesions proximal to the gastroduodenal artery may be ligated if there is sufficient collateral flow to the liver. For lesions distal to this artery, surgical resection and reconstruction is required. Selective embolization of intrahepatic or subhepatic aneurysms may be an effective alternative in high-risk patients. We had two cases of aneurysm of the hepatic artery diagnosed at our institution over the course of 18 months. Excellent results were obtained from surgical revascularization of the liver in both cases.

Glioblastoma multiforme after radiotherapy for acromegaly.

A case of glioblastoma multiforme that occurred 14 years after radiotherapy for acromegaly is presented. The striking correspondence between the anatomy of the tumor and the geometry of the radiation ports is suggestive of a causal relationship. Previously reported cases of radiation-associated glioma are reviewed, and a brief appraisal of the evidence for induction of these lesions by radiation is presented. The differentiation of radiation-associated neoplasms from radionecrosis is also discussed.

Meningiomas associated with large cysts with neoplastic cells in the cysts walls. Report of two cases.

Two adults presented with frontal lobe masses. As visualized by computerized tomography, both lesions were large cysts with contrast-enhancing mural nodules and enhancing circumferential rims. En bloc resections of the mural nodules and cyst walls were performed. Pathological evaluation of each nodule disclosed a meningioma, and neoplastic cells were found in the distant cyst walls. Although the walls of large cysts associated with some meningiomas have been composed of reactive glia or collagen, the neoplastic character of the cysts in the present cases underscores the need for resection and careful pathological evaluation of the large cysts associated with meningiomas.
