Posterior translation of the spinal cord occurs passively following laminoplasty with the presence lordotic spine and availability of a space for the spinal cord to shift. This study is to predict the distance of posterior spinal cord migration after expansive laminoplasty at different cervical levels based on measurement of posterior translation of the spinal cord in normal cervical morphometry.

Mini open carpal tunnel release using Knifelight: evaluation of the safety and effectiveness of using a single wrist incision (cadaveric study)

Teh KK, Ng ES, Choon DS

J Hand Surg Eur Vol, 2009 Aug;34(4):506-10.

PMID: 19675032 DOI: 10.1177/1753193409100962

This cadaveric study evaluates the margin of safety and technical efficacy of mini open carpal tunnel release performed using Knifelight (Stryker Instruments) through a transverse 1 cm wrist incision. A single investigator released 32 wrists in 17 cadavers. The wrists were then explored to assess the completeness of release and damage to vital structures including the superficial palmar arch, palmar cutaneous branch and recurrent branch of the median nerve. All the releases were complete and no injury to the median nerve and other structures were observed. The mean distance of the recurrent motor branch to the ligamentous divisions was 5.7 +/- 2.4 mm, superficial palmar arch was 8.7 +/- 3.1 mm and palmar cutaneous branch to the ligamentous division was 7.2 +/- 2.4 mm. The mean length of the transverse carpal ligament was 29.3 +/- 3.7 mm. Guyon's canal was preserved in all cases.

Tang IP, Prepageran N, Subrayan V, Tajunisah I

Med J Malaysia, 2008 Oct;63(4):337-8.

PMID: 19385499 MyJurnal

Optic neuropathy, an uncommon manifestation occurs in 5% of patients with Graves' ophthalmopathy. Its outcome is good if early and proper treatment given. We reported a 49 years old male patient of Graves' disease with bilateral optic neuropathy. He underwent bilateral transnasal endoscopic orbital decompression with marked improvement of visual acuity bilaterally. The preoperative visual acuity was 6/36 in his right eye and 6/60 in his left eye. Two days after operation, his visual acuity was 6/12 in his right eye and 6/24 in his left eye. Transnasal endoscopic orbital decompression is a choice of treatment in optic neuropathy in thyroid ophthalmopathy after trial of corticosteroids.

Med J Malaysia, 2008 Mar;63(1):67-8.

PMID: 18935740

We report a male patient of Graves' Disease with bilateral exophthalmos who had undergone bilateral transnasal endoscopic orbital decompression with subsequent improvement of 3 mm in orbital proptosis bilaterally without any complications. Transnasal endoscopic orbital decompression is recommended as an alternative to traditional decompression techniques especially for purely cosmetic reasons.

Georgian Med News, 2024 Jun.

PMID: 39230213

BACKGROUND: To evaluate the treatment outcomes of lateral interbody bone graft surgery and posterior percutaneous screws for lumbar spinal stenosis Methods: This is a cross-sectional descriptive study. There were 27 patients with 30 segments of surgery diagnosed with lumbar spinal stenosis that were surgically treated with the XLIF method. Clinical outcomes measured included VAS scores for lower back pain and leg pain, ODI, and JOA scores. Magnetic resonance imaging of the lumbar spine after surgery was used to evaluate indirect decompression. X-ray or CT scan to evaluate bone fusion after 6 months of surgery. Differences were determined by independent T-test.

RESULTS: There were 27 patients with 30 segments of surgery. They were 12 males and 15 females with an average age of 58.81±8.1. There was significant improvement in VAS for lower back pain from 7.11±1.31 to 3.67±1.3, VAS for leg pain from 6.81±2.19 to 1.59±1.89, ODI from 26.41±8.95 to 13.69±8.34, and JOA score from 7.63±2.87 to 13.5±1.73. A-P diameter increased 134%, lateral diameter increased 120%, lateral recess depth increased 166%, disc height increased 126%, foraminal height increased 124%, spinal canal area increased 30%. The p-values were all <0.001. The average hospital stay was 6.79±3.01 days. Complications included 1 pedicle screw malformation, 1 ALL avulsion fracture, 1 abdominal herniation, 1 venous damage, 1 failure.

CONCLUSION: XLIF surgery presents a favorable option for patients with lumbar spinal stenosis. This is a minimally invasive surgical method that reduces pain, reduces bleeding, and is effective in indirectly decompressing the spinal canal both clinal and imaging.

The use of intraoperative CT navigation for posterior cervical spine foraminotomy

Tan BH, Sockalingam S, Ganesan D

Br J Neurosurg, 2025 Apr;39(2):262-265.

PMID: 37345453 DOI: 10.1080/02688697.2023.2225611

OBJECTIVES: Posterior cervical foraminotomy is a surgical procedure used to treat unilateral cervical radiculopathy. It provides direct decompression of the nerve root without the necessity of fusion while maintaining cervical mobility. With the advancement in image-guidance technology and minimal access techniques, intra-operative CT has provided a safer, more accurate instrumentation placement with less radiation exposure to operative staff and provides better anatomical visualization quality compared to traditional intra-operative imaging techniques. This case series aims to address the applications of advanced image guidance in posterior cervical foraminotomy and describe the nuances.

METHOD: A technical report on a series of seven cases on intraoperative CT navigation for posterior cervical foraminotomy surgery. Posterior cervical foraminotomy was performed in all patients under CT guided navigation system without an image intensifier. In one case after the foraminotomy, the extruded disc was carefully removed by gentle retraction.

RESULT: From 1 January 2020 to 31 December 2021, a total of seven patients with nine cervical foraminotomy procedures were performed using the aid of CT-guided navigation. The series comprised five women and two men whose mean age was 50.6 years. In all cases, the radiculopathy symptoms were diminished significantly. There were no cases of instability on the dynamic cervical radiograph. There were no complications during the surgical procedure.

CONCLUSION: The navigation also allows the surgeon to localise the index level accurately and appraise the adequacy of the intended decompression in three planes of the CT scan image. The ability to perform accurate spine navigation would be the precursor for robotic spinal surgery.

Fulltext Tarsal tunnel syndrome caused by ganglion

Ng WM, Chan KY

Med J Malaysia, 2004 Dec;59 Suppl F:69-71.

PMID: 15941169

We report a case of delayed diagnosis of tarsal tunnel syndrome caused by a ganglion arising from the talo-calcaneal joint. Unusually the symptoms were mainly due to the lateral planter nerve compression with a positive Tinel's sign. A surgical decompression was successful in relieving the dysaesthesia in spite of a 7 years history.

Endoscopic, endonasal decompression of spinal stenosis with myelopathy secondary to cranio-vertebral tuberculosis: two cases

Puraviappan P, Tang IP, Yong DJ, Prepageran N, Carrau RL, Kassam AB

J Laryngol Otol, 2010 Jul;124(7):816-9.

PMID: 20003599 DOI: 10.1017/S0022215109992271

Tuberculosis can cause extensive osseo-ligamentous destruction at the cranio-vertebral junction, leading to atlanto-axial instability and compression of vital cervico-medullary centres. This may manifest as quadriparesis, bulbar dysfunction and respiratory insufficiency.

Fulltext Tophaceous gout causing atlanto-axial subluxation mimicking rheumatoid arthritis: a case report

Wazir NN, Moorthy V, Amalourde A, Lim HH

J Orthop Surg (Hong Kong), 2005 Aug;13(2):203-6.

PMID: 16131689 DOI: 10.1177/230949900501300220

This is a case report of an extremely rare condition of atlanto-axial subluxation secondary to gouty arthritis, which mimicked rheumatoid arthritis at presentation. Gouty arthritis involving the spine is a rare condition. We highlight a case of gouty arthritis involving the atlanto-axial joint resulting in joint instability, subluxation, and neurological deficit. A 66-year-old obese woman who had a polyarticular disease for the previous 3 years presented with neck pain and progressive neurology. A 2-stage procedure was performed: posterior decompression and occipitocervical fusion followed by further anterior trans-oral decompression. However, after an initial neurological improvement, she succumbed to aspirational pneumonia and septicaemia. Atlanto-axial subluxation caused by gouty arthritis can present in the same way as rheumatoid arthritis. Therefore, the possibility of this as a differential diagnosis should be kept in mind.
