Fulltext Spinal infection--an overview and the results of treatment

Razak M, Kamari ZH, Roohi S

Med J Malaysia, 2000 Sep;55 Suppl C:18-28.
PMID: 11200039

A retrospective review of thirty-eight patients (16 males and 22 females) with spinal infection between 1993 and 1998 revealed that the mean age was 39.9 years and the peak incidence was in the 5th decade of life. Infections in thirty-two patients (84.2%) were tuberculous in origin, 13.2% were pyogenic and 2.6% were fungal. Back pain was a symptom in 94.7% while 55.8% had neurological deficits, of which two-thirds were tuberculous in origin. Twenty-two patients (57.9%) had an impaired immune status secondary to pulmonary either tuberculosis, diabetes mellitus, intravenous drug abuse, prolonged steroid treatment, malnutrition, or advanced age. History of contact with tuberculous patients was elicited in 31.3%, extraskeletal tuberculosis was found in 28.1%, while Mantoux test was only positive in 53.1% of tuberculous patients. Majority of the cases (57.9%) involved lumbar vertebra. The histopathological examination was only positive in 22.2% from material taken via CT guided biopsy but 93.3% were found to be conclusive from open biopsy. 4 out of 5 patients who had a pyogenic infection were treated conservatively and produced a good result. There was no difference in outcome for tuberculosis patients treated with either the 3 drug or 4 drug regimen. Anterior decompression and bone grafting in tuberculous patients was superior in terms of a faster fusion rate, early pain relief and prevention of kvphotic deformity. The initial neurological deficit did not reflect the future prognosis of patients with spinal infection.

Is C1 lateral mass screw placement safe for the Chinese, Indians, and Malays? An analysis of 180 computed tomography scans

Lee CK, Tan TS, Chan C, Kwan MK

J Orthop Surg (Hong Kong), 2017 01;25(1):2309499017692683.
PMID: 28211302 DOI: 10.1177/2309499017692683

INTRODUCTION: C1 lateral mass (C1LM) screw is a common procedure in spine surgery. However, related studies are lacking in Asia. We aim to determine the safety of C1LM screw for the Chinese, Indians, and Malays.
METHODS: Three-dimensional computed tomographies of 180 subjects (60 from each ethnic) were analyzed. The length and angulations of C1LM screw and the location of internal carotid artery (ICA) in relation to C1LM were assessed and classified according to the classification by Murakami et al. The incidence of ponticulus posticus (PP) was determined and the differences among the population of these three ethnics were recorded.
RESULTS: The average base length was 8.5 ± 1.4 mm. The lengths within the lateral mass were between 14.7 ± 1.6 mm and 21.7 ± 2.3 mm. The prevalence of PP was 8.3%. 55.3% (199) of ICA were located in zone 0, 38.3% (138) in zone 1-1, 6.4% (23) in zone 1-2, and none in zone 1-3 and zone 2. The average angulation from the entry point to the ICA was 8.5° ± 6.4° laterally. The mean distance of ICA from C1 anterior cortex was 3.7 ± 1.7 mm (range: 0.6∼11.3). There was no difference in distribution of ICA in zone 1 among the three population (Chinese-47%, Indians-61%, and Malays-53%; p > 0.05).
CONCLUSIONS: No ICA is located medial to the entry point of C1LM screw. If bicortical purchase of C1LM screw is needed, screw protrusion of less than 3 mm or medially angulated is safe for ICA. The incidence of PP is 8.3% with higher prevalence among the Indian population.

Fulltext Metastatic cervical carcinoma presenting as psoas abscess and osteoblastic and lytic bony metastases

George J, Lai FM

Singapore Med J, 1995 Apr;36(2):224-7.
PMID: 7676275

A 60-year-old Chinese lady presented with a left flank mass and weight loss. Plain films showed a sclerotic L1 vertebral body, osteopenic L2 and L3 vertebral bodies and loss of left psoas outline. However initially unrevealed history of previous carcinoma of the cervix caused confusion as to the aetiology of a sclerotic vertebral body associated with an left flank collection. Psoas abscess with adjacent bony osteomyelitis was initially suspected. The left flank mass turned out to be an infected necrotic large metastatic lymph node compressing the lower pole of the left kidney. The sclerotic and osteopenic vertebral bodies represented an unusual presentation of bony cervical carcinoma metastases.
