Abscess superimposed on brain tumor: two case reports and review of the literature.

BACKGROUND: An abscess involving an already present brain tumor is a rare occurrence. METHOD: Two cases of an abscess superimposed on a brain tumor are presented and discussed. The medical literature is reviewed, and all reported cases are compared to our own. RESULTS: Only 15 cases of an abscess associated with a brain tumor were found in the literature, to which we add 2 of our own. About 60% were intrasellar or parasellar tumors. The origin of such an abscess at this location is by direct extension of the germs from a contiguous infected sinus. Our 2 additional cases were away from the sinuses. One is an ependymoma of the posterior fossa, and the other, a falcotentorial occipital meningioma, each with a superimposed abscess. CONCLUSIONS: We propose an alternate route for the formation of an abscess in conjunction with a brain tumor.

Cranial osteomas: their classification and management. Report on a giant osteoma and review of the literature.

BACKGROUND: Cranial osteomas are regarded by some as very common; yet their classification, symptomatology, and management have been neglected. METHODS: We report on a giant enostotic convexity osteoma and have reviewed the medical literature. RESULTS: A new comprehensive classification for cranial osteomas is proposed: (1) intraparenchymal, (2) dural, (3) skull base, and (4) skull vault. The latter is in turn, subdivided into exostotic and enostotic variants. Three symptom producing enostotic convexity osteomas have been reported in the world literature. We also describe a giant enostotic skull vault osteoma and propose an original surgical technique used to successfully resect this unusual tumor. CONCLUSIONS: Most cranial osteomas are asymptomatic and need not be resected. Those that are symptomatic should be managed properly. Their excision, if nor properly performed, may lead to unforeseen cerebral complications.

Acute compartment syndrome following non-contact football injury.

Acute compartment syndrome in athletes, although rare, is a limb threatening condition which warrants emergency treatment. The case of a footballer with acute compartment syndrome of the left lower leg, without any preceding direct trauma to the calf, is reported. To our knowledge this is the only description of acute atraumatic compartment syndrome secondary to rupture of one of the heads of gastrocnemius.

Carpal tunnel syndrome in the mucopolysaccharidoses and mucolipidoses.

Children with a mucopolysaccharidosis or mucolipidosis suffer progressive disability of the hands, particularly in relation to dysfunction of the median nerve. This is an increasing problem because bone-marrow transplantation has dramatically improved survival without apparently changing the musculoskeletal manifestations. We have reviewed 48 children with these syndromes who required carpal tunnel decompression, recording symptoms, signs, radiological, electrophysiological and operative findings, histology and upper-limb function. In these children the carpal tunnel syndrome differs from that seen in adults. Symptoms are rare but signs such as decreased sweating, pulp atrophy, thenar wasting and manual clumsiness are much more common. At operation, the flexor retinaculum was thickened and a mass of white tenosynovium engulfed the flexor tendons. Most patients had some definite nerve constriction with a thickened epineurium. Functional improvement was seen after early decompression, with some benefit from simultaneous tendon release. Regular physiotherapy helped to maintain increased hand movement. We describe our assessment protocol, the physiotherapy and operative regime and the standard functional review which helps to maximise function in the hands and upper limbs of these children.

Intraoperative arthrography and the Ilizarov technique. Role in the correction of paediatric deformity and leg lengthening.

We performed intraoperative arthrography of the knee in 12 children with congenital short femur, Blount's disease or Ollier's disease in whom the Ilizarov technique was used for correction of deformity, leg lengthening or both. In each case, arthrography revealed a joint surface considerably different from that assumed from plain radiographs, and resulted in a change in the placement of our reference wires before application of the frame. This gave significant improvement in the mechanical axis obtained at the time of removal of the frame. The technique is safe, cheap and easy to perform. It is a useful adjunct to the application of the Ilizarov frame when used for complex lengthening and correction of deformity in the leg.

An unexpected complication of DVT prophylaxis.

We report a case in which a complication of routine chemoprophylaxis with subcutaneous low-molecular-weight heparin led to the postponement of a total hip replacement. This unusual reaction reinforces the current debate regarding the use of chemoprophylaxis for joint replacement surgery.

The AO unreamed nail: friend or foe.

Twenty-nine tibial shaft fractures were stabilized with the AO unreamed tibial nail. These included 13 type A fractures, 11 type B fractures and five type C injuries. Fourteen of the fractures were open. The AO unreamed tibial nail was the primary device used in all cases. Our series suggests that this is an easy device to insert and that its multiple locking options confer an advantage for the management of distal fractures. It also has a low soft-tissue complication rate. There was a delay in full patient mobilization and in the progression to fracture union. There was also a significant degree of implant failure with screw breakage in 21 per cent. This necessitated a high rate of secondary operative intervention. The high incidence (55 per cent) of anterior knee pain was also worrying and frequently necessitated nail removal. We feel that this implant may still have a role for distal fractures and in the multiply injured patient but do not feel that, in its current form, it is the ideal implant for the majority of tibial shaft fractures.

The check X-ray: an unnecessary investigation after hip fracture fixation?

An X-ray-based image intensification system is a necessary operative aid in many orthopaedic procedures. Technological advances have not only increased the resolution of these systems, but allow the production of thermal images. We have compared such images obtained at the time of surgery with postoperative radiographs in 80 patients who underwent closed reduction and internal fixation for proximal femoral fractures. The films were independently assessed with particular reference to fracture reduction and the adequacy of fixation. In no case did the postoperative radiograph provide additional information. We therefore suggest that a postoperative radiograph is only necessary in exceptional circumstances. This is of significance in relation to patient discomfort, morbidity and radiation exposure. It also has important financial and manpower implications.
