Impact Of Sarcopenia On Effectiveness Of Lumbar Decompression Surgery In Patients With Lumbar Spinal Stenosis London Spine

The London Spine Unit : finest spinal centre in UK


Published article

Patients with sarcopenia and lumbar spinal stenosis may have longer postoperative recovery time, and the effectiveness is worse than that of non-sarcopenic patients. Therefore, for elderly patients with lumbar spine disease, it is suggested to improve preoperative assessment of sarcopenia, which can help to identify patients with sarcopenia at risk of poor surgical prognosis in advance, so as to provide rehabilitation guidance and nutritional intervention in the perioperative period.

Abstract

Objective: To investigate the impact of sarcopenia on effectiveness of lumbar decompression surgery in patients with lumbar spinal stenosis.

Methods: The clinical data of 50 patients with lumbar spinal stenosis who met the selection criteria between August 2017 and December 2020 were retrospectively analyzed. According to the diagnostic criteria of the European Working Group on Sarcopenia in Older People (EWGSOP), based on the calculation of the skeletal muscle index (SMI) at the L 3 level, SMI<45.4 cm 2/m 2 (men) and SMI<34.4 cm 2/m 2 (women) were used as the diagnostic threshold, the patients were divided into sarcopenia group (25 cases) and non-sarcopenia group (25 cases). There was no significant difference in gender, age, disease duration, level of lumbar spinal stenosis, surgical fusion level, and comorbidity between the two groups ( P>0.05); the body mass index in sarcopenia group was significantly lower than that in non-sarcopenia group ( t=-3.198, P=0.002). Clinical data of the two groups were recorded and compared, including operation time, intraoperative blood loss, postoperative drainage volume, hospitalization stay, and complications. The visual analogue scale (VAS) scores of low back pain and sciatica and Oswestry disability index (ODI) scores were recorded preoperatively and at last follow-up. The effectiveness was evaluated according to modified MacNab standard.

Results: There was no significant difference between the two groups in terms of operation time, intraoperative blood loss, and postoperative drainage volume ( P>0.05). However, the hospitalization stay in sarcopenia group was significantly longer than that in non-sarcopenia group ( t=2.105, P=0.044). The patients were followed up 7-36 months (mean, 29.7 months). In sarcopenia group, 1 case of dural tear and cerebrospinal fluid leakage occurred during operation, as well as 1 case of internal fixator loosening during follow-up; 1 case of incision exudation and poor healing occurred in each of the two groups, and no adjacent segment degeneration and deep vein thrombosis of lower extremity occurred in the two groups during follow-up. There was no significant difference in the incidence of complications (12% vs. 4%) between the two groups ( χ 2=1.333, P=0.513). VAS scores in low back pain and sciatica as well as ODI scores in two groups significantly improved when compared with preoperative results at last follow-up ( P<0.05). The differences of VAS scores in low back pain and ODI scores before and after operation in sarcopenia group were significantly lower than that in non-sarcopenia group ( P<0.05). However, there was no significant difference of that in VAS scores of sciatica between the two groups ( t=-1.494, P=0.144). According to the modified MacNab standard, the excellent and good rate of the sarcopenia group was 92%, and that of the non-sarcopenia group was 96%, showing no significant difference between the two groups ( χ 2 =1.201, P=0.753).

Patients with sarcopenia and lumbar spinal stenosis may have longer postoperative recovery time, and the effectiveness is worse than that of non-sarcopenic patients. Therefore, for elderly patients with lumbar spine disease, it is suggested to improve preoperative assessment of sarcopenia, which can help to identify patients with sarcopenia at risk of poor surgical prognosis in advance, so as to provide rehabilitation guidance and nutritional intervention in the perioperative period.

目的: 探究肌肉减少症(简称肌少症)对传统腰椎后路开放手术治疗腰椎管狭窄症患者临床疗效的影响。.

方法: 回顾分析2017年8月—2020年12月符合选择标准的50例腰椎管狭窄症患者临床资料,依据欧洲老年人肌少症工作组(EWGSOP)的诊断标准,基于计算L 3水平骨骼肌指数(skeletal muscle index,SMI),以SMI<45.4 cm 2/m 2(男性)和SMI>34.4 cm 2/m 2(女性)作为诊断阈值分为肌少症组(25例)和非肌少症组(25例)。两组患者性别、年龄、病程、腰椎管狭窄节段、手术融合节段、合并症等一般资料比较差异均无统计学意义( P>0.05);肌少症组患者身体质量指数明显低于非肌少症组,差异有统计学意义( t=−3.198, P=0.002)。记录并比较两组患者手术时间、术中出血量、术后引流量、住院时间、并发症,术前及末次随访时腰痛和坐骨神经痛疼痛视觉模拟评分(VAS)、Oswestry功能障碍指数(ODI);采用改良MacNab评定标准评价手术疗效。.

结果: 两组手术时间、术中出血量及术后引流量比较差异无统计学意义( P>0.05);肌少症组住院时间显著长于非肌少症组( t=2.105, P=0.044)。两组患者均获随访,随访时间7~36个月,平均29.7个月。肌少症组术中出现硬膜撕裂及脑脊液漏1例、随访期间内固定物松动1例,两组各发生1例切口渗液、愈合不良,随访期间两组均未发生邻近节段退变及下肢深静脉血栓形成;两组并发症发生率(12% vs. 4%)比较差异无统计学意义( χ 2 =1.333, P=0.513)。末次随访时,两组患者腰痛及坐骨神经痛VAS评分和ODI评分均较术前显著改善( P<0.05)。肌少症组患者腰痛VAS评分及ODI评分手术前后差值显著低于非肌少症组( P<0.05),两组坐骨神经痛VAS评分手术前后差值比较差异无统计学意义( t=−1.494, P=0.144)。按照改良MacNab评定标准评价疗效,肌少症组优良率为92%,非肌少症组优良率为96%,两组差异无统计学意义( χ 2=1.201, P=0.753)。.

结论: 与非肌少症患者相比,肌少症合并腰椎管狭窄症患者术后康复时间可能更长,手术临床疗效更差。肌少症需引起脊柱外科医生关注,可通过早期筛查发现有手术预后不良风险的肌少症患者,从而在围术期进行康复指导和营养干预。.

Truly excellent results! I was diagnosed with lumbar stenosis after experiencing increasing pain in both legs. An MRI and consultation carried out at short notice confirmed this. Mr Akmal recommended that a spacer should be inserted in my lower back to correct the problem and release the nerves from the narrowing caused by stenosis. The operation was conducted very professionally and without pain. After the first two weeks the pain started to subside as expected. After 4 weeks I was completely back to normal. The result is exceptionally good and I feel renewed, with no pain whatsoever and a regained posture, ready to resume a normal life. I cannot recommend The London Spine Unit highly enough. They are medical magicians!

Sciatica My mother was in absolute agony for more than 3 months due to sciatica. It just came out of nowhere and took her out of action. From working full time she went straight to being bed bound and unable to carry out simplest of actions.The pain was 9/10 and she was bed bound for those three months. Multiple trips to A&E and GP and they wouldn't class it as an emergency therefore they wouldn't do anything about it other than upgrading the painkillers which did next to nothing for my mother. I couldn't bear to watch my mother sleeping on A&E bench in pain for 7 hours, just to be told by doctors that she wouldn't be kept in. I remember her joining her hands and begging the doctors to stop the pain which broke my heart. I then started doing research on google and London spine unit came up with Dr Mo AKMAL's profile and review. First meeting with Dr AKMAL was via ZOOM as my mother was bed bound. Dr AKMAL spoke to me and my mom and told us that this is nothing to worry about and that the pain would be 100% gone.Dr AKMAL assured us to visit the hospital so he could physically inspect my mother and give us the best solution. One trip to the london spine unit and Dr AKMAL advised us that the best solution would be to carry out Minimally invasive disectomy. Dr AKMAL advised that due to my mother being bed bound for a while, steroid injection might not give the result that my mother wishes. Dr AKMAL was very confident and showed us some videos from other patients who had gone through the same ordeal. The biggest thing i noticed between before and after was the smile on the patients face. Dr AKMAL was constantly assuring my mother throughout the meeting that he would take care of her pain and gave her 100% confidence that the result would be delivered.He promised her that she would be walking pain free the same day after the operation. Before the operation Dr GURUNG was consulted multiple times and he also was very helpful. Right after the surgery, as Dr AKMAL promised, my mother was walking and the biggest thing was that the pain was gone. My mother had forgotten to smile for three months and there i saw her smiling again. Dr AKMAL and Dr GURUNG gave us brilliant aftercare and informed us that just give them a ring if there was any issue. Its been several weeks now and my mother is heading towards complete recovery without any issues. The pain is completely gone and anyone who is reading this going through the same horrible sciatica pain you must come and see Dr AKMAL. Thank you Dr AKMAL and your whole team for helping my mom achieve this pain free life.

Extraordinary Care My 81 year old mother who has retired in Ghana was suffering from severe lower back pain so a local surgeon put her through discectomy with hardware (spine screws). The procedure was essentially botched, with one screw breaching her spinal canal resulting in extreme pain; unable to walk, pins and needles and numbness in the left leg. The hardware subsequently had become infected and loosened as a result. Her life after this surgery was the worse she has ever experienced in all her life. She had no doubt that she was eventually to die from the infection and pain. Fortunately, through diligent search, we found Mr Akmal and his team at The UK Spine Centre. She had a zoom consultation and with a ready MRI and CT scan, Mr Akmal knew exactly how to have her back to fitness and a better quality of life. She travelled to England on 26 March 2022 and had the surgery on 11 April 2022. It was a day-case. It lasted no more than 1 hour 30 minutes. She was on my feet within 2 hours pain free - still pain free 5 weeks on! To her this is simply a miracle ! She is grateful to Jehovah God for Mr Akmal and his team - thoroughly professional bunch at the top of their game. No one deserves to suffer the pain she experienced for two years. She seriously recommends Mr Akmal and his team for anything SPINE!

Bilateral discectomy and dynamic stabilisation for complete foot drop From the first phone call, the team at London Spine have been amazing. I had severe symptoms following an L4/L5 disc injury from playing sports and had complete foot drop. Mr Akmal and his team treated the situation incredibly sensitively, as I had risk of permanent damage. The whole process was so quick, from initial consultation to operation was about 96 hours. On the day of the operation, the nurses couldn’t have been more helpful, attentive and calming. The surgery was flawless, with absolutely zero pain from the operation following. I am now 8 weeks from a bi-lateral discectomy and dynamic stabilisation procedure and have regained full use of my leg and toes, with a complete range of motion also. Mr Akmal’s aftercare has been first class, with regular calls from his team in the 2 weeks following the surgery, to the final consultation and discharge. Thanks so much for giving me my life back

Excellent treatment Mr Mo Akmal treated me very successfully for 2 torn discs in my back. I was in tremendous pain before I was referred to him. The treatment I received from him was excellent and he communicated with me very well throughout the whole process. I am eternally grateful to Mr Akmal for sorting out my back and would highly recommend him.

I had a massive bulging disk on my back… I had a massive bulging disk on my back compressing my nerve for three years. It caused me excruciating pain and almost left me disabled. I was on both crutches and completely homebound due to the severity of pain and mobility limitations. I had my lumber surgery two weeks ago and walked out of hospital within a few hours pain free on my right leg that was almost paralysing prior to surgery. The disk was shaved off releasing the nerve completely. Two days after surgery I had excruciating pain on my head that is unexplained as I had CT scan and MRI which were all fine. Dr Akmal has suggested it could be from the anaesthetic. I am extremely grateful to Dr Akmal and his very welcoming and cari g team. I would highly recommend his clinic as I have had excellent recovery.

Thank you Mr Aklam After having a poor and very slow experiance in glasgow . I contacted Mr mo Amlam . Who is a true gentleman, great listener and paitent . We transfered my scans and treatments from glasgow to harley street . Mr Aklams p.a arranged a quick zoom to start our contact .I then went down for a meeting and examination and what should have been a spec scan .only to be told of a UK shortage . So 4 weeks later the scan took place in wellington hospital . Before I traveled back to glasgow. 5 days later I got a call to book me in to 19 harley street for a l3 and l4 debridement and stabilisation. The opp took place on 24th March. 2hours I was out walking 4 hours later . My pain in back groin and foot was all gone .thanks to Mr aklam . Top of his craft but more importantly pouts his patients first .he really wants to help you get better. Thank you so much Mr Robert harvey

Amazing service and an amazing treatment! I can't thank Mr Akmal and team at the London Spine Unit enough for their help. I had a herniated disc in my back which was causing pain and restrictions. Compared to other offers of surgery (e.g. several nights in hospital), the day surgery and minimally invasive procedure were hugely appealing. I am now 3 weeks post surgery, have no pain and am recovering incredibly quickly if I compare myself to friends who have had a similar procedure. it was truly remarkable, straightforward and the team were kind, friendly and always helpful. very highly recommended!
