Innervation of vastus lateralis muscle.

The lateral surgical approach to the proximal femur potentially damages the nerve supply to the vastus lateralis (VL) muscle. This study describes the detailed anatomy of the nerve supply to the VL muscle based on dissection of ten cadaveric lower limbs. In all specimens, a single nerve trunk arose from the femoral nerve, which is most subsequently divided into two main divisions. These divisions gave two branches each. These branches coursed from anteriorly and proximally to posteriorly and distally within the muscle. When the muscle was reflected anteriorly from its attachment to the linea aspera, there was no damage to its innervation. Splitting of the VL in the midlateral line of the femur, however, resulted in denervation of the posterior half of the muscle. Precise knowledge of the nerve supply to the VL will help avoid iatrogenic denervation of the muscle in surgical procedures at the proximal femur through the lateral approach.

Paget sarcoma of the spine: Scottish Bone Tumor Registry experience.

STUDY DESIGN: Retrospective case study of 13 cases of Paget sarcoma of the spine accrued from a prospectively collected Tumor Registry database. OBJECTIVES: To analyze the clinical, radiologic, and histologic features of Paget sarcoma of the spine and to determine the factors influencing the prognosis. SUMMARY OF BACKGROUND DATA: Paget disease of bone is a common disorder with the spine being involved in over 50% of patients. However, sarcomatous degeneration in the vertebral column is an extremely rare complication. There is very little in the literature with regard to clinical presentation and prognosis of patients with Paget sarcoma affecting the vertebral column. METHODS: Between January 1944 and December 2003, 89 patients were registered with a diagnosis of Paget sarcoma in the Scottish Bone Tumor Registry. Thirteen patients with Paget sarcoma of the spine were analyzed with regard to their clinical, radiologic, and histopathologic features along with the prognostic predictors. RESULTS: The mean age was 66.9 years (range: 56-79 years). There were 10 males and three females. There were seven cases involving the sacral spine (63.6%), three cases involving lumbar vertebrae, two affecting the dorsal spine, and one with diffuse dorsolumbar involvement (D11-L3). The mode of presentation was progressively increasing low back pain (in all 13), unilateral sciatica (six; left-sided, five; right-sided, one), bilateral sciatica (two), lower limb weakness (eight), and autonomic dysfunction (four). Ten of 13 cases (76.9%) were osteosarcoma. The rest were chondrosarcoma (n = 1), fibrosarcoma (n = 1), and malignant fibrous histiocytoma (n = 1). Decompression laminectomy was performed in three patients with progressive neurologic deficit. Eight patients had received radiotherapy. The mean survival was 4.22 months. CONCLUSIONS: This series confirmed that Paget sarcoma of the spine has a very poor prognosis. We found a constellation of symptomatology in patients with sarcomatous Paget spine resulting from radiculomedullary compression, primarily lumbosacral involvement and predominantly osteosarcomatous histology. There was no significant difference observed on the overall prognosis of the patients with Paget sarcoma of the spine in the last 6 decades.

Outcome after surgery for fracture of the hip in patients aged over 95 years.

Despite the increase in numbers of the extreme elderly, little data is available regarding their outcome after surgery for fracture of the hip. We performed a prospective study of 50 patients aged 95 years and over who underwent this procedure. Outcome measures included morbidity, mortality, hospital stay, residential and walking status. Comparison was made with a control group of 200 consecutive patients aged less than 95 years who had a similar operation. The mortality at 28 and 120 days was higher (p = 0.005, p = 0.001) in the patients over 95 years. However, the one-year cumulative post-operative mortality was neither significantly different between the two groups (p = 0.229) nor from the standardised mortality rate for the age-matched population (p = 0.445). Predictors of mortality included the ASA grade, the number of comorbid medical conditions and active medical problems on admission. Patients over 95 were unlikely to recover their independence and at a mean follow-up of 29.3 months (12.1 to 48) 96% required permanent institutional care.

Subarachnoid fat embolism complicating autologous fat grafting following translabyrinthine excision of acoustic neuroma.

A 64-year-old man had complete excision of an acoustic schwannoma via the translabyrinthine route and the mastoid cavity was packed with fat. Post-operatively there were two episodes of aseptic meningitis and CT scanning demonstrated migration of fat into the basal subarachnoid CSF spaces. This unusual complication should be recognized and differentiated from both true infective meningitis and aseptic meningitis from other causes.
