Anatomic location of the first dorsal extensor compartment for surgical De-Quervain’s tenosynovitis release:A cadaveric study

BACKGROUND De-Quervain’s tenosynovitis is a disorder arising from the compression and irritation of the first dorsal extensor compartment of the wrist.Patients who fail conservative treatment modalities are candidates for surgical release.However,risks with surgery include damage to the superficial radial nerve and an incomplete release due to inadequate dissection.Currently,there is a paucity of literature demonstrating the exact anatomic location of the first dorsal extensor compartment in reference to surface anatomy.Thus,this cadaveric study was performed to determine the exact location of the first extensor compartment and to devise a reliable surgical incision to prevent complications.AIM To describe the location of the first dorsal compartment in relation to bony surface landmarks to create replicable surgical incisions.METHODS Six cadaveric forearms,including four left and two right forearm specimens were dissected.Dissections were performed by a single fellowship trained upper extremity orthopaedic surgeon.Distance of the first dorsal compartment from landmarks such as Lister’s tubercle,the wrist crease,and the radial styloid were calculated.Other variables studied included the presence of the superficial radial nerve overlying the first dorsal compartment,additional compartment subsheaths,number of abductor pollicis longus(APL)tendon slips,and the presence of a pseudo-retinaculum.RESULTS Distance from the radial most aspect of the wrist crease to the extensor retinaculum was 5.14 mm±0.80 mm.The distance from Lister’s tubercle to the distal aspect of the extensor retinaculum was 13.37 mm±2.94 mm.Lister’s tubercle to the start of the first dorsal compartment was 18.43 mm±2.01 mm.The radial styloid to the initial aspect of the extensor retinaculum measured 2.98 mm±0.99 mm.The retinaculum length longitudinally on average was 26.82 mm±3.34 mm.Four cadaveric forearms had separate extensor pollicis brevis compartments.The average number of APL tendon slips was three.A pseudo-retinaculum was present in four cadavers.Two cadavers had a superficial radial nerve that crossed over the first dorsal compartment and retinaculum proximally(7.03 mm and 13.36 mm).CONCLUSION An incision that measures 3 mm proximal from the radial styloid,2 cm radial from Lister’s tubercle,and 5 mm proximal from the radial wrist crease will safely place surgeons at the first dorsal compartment.

Anatomic relationship of extensor indicis propius and extensor digitorum communis: Implications for tendon transfer

BACKGROUND The extensor indicis proprius(EIP)tendon is a frequently used donor for a variety of tendon transfers,most commonly for reconstruction of the extensor pollicis longus(EPL).EIP is known to have frequent anatomic variants including split tendons and variations in tendon arrangement.AIM To characterize the anatomy of the EIP at the level of the extensor retinaculum,where tendon harvest is often performed,and share our preferred technique for EIP to EPL transfer.METHODS Twenty-nine fresh-frozen cadaveric forearms without history of forearm or hand injury or surgery were dissected.Tendon circumference and relationship of the EIP and extensor digitorum communis to the index(EDCI)at the metacarpophalangeal(MCP)joint and the distal extensor retinaculum were recorded.Distance from the distal extensor retinaculum to the EIP myotendinous junction was measured.RESULTS EIP was ulnar to the EDCI in 96.5%of specimens(28/29)at the distal edge of the extensor retinaculum.In the remaining specimen,EIP was volar to EDCI.Tendon circumference at the distal extensor retinaculum averaged(9.3 mm±1.7 mm)for EDCI and 11.1 mm(±2.7 mm)for EIP(P=0.0010).The tendon circumference at the index MCP joint averaged 11.0 mm(±1.7 mm)for EDCI and 10.6 mm(±2.1 mm)for EIP(P=0.33).EIP had a greater circumference in 76%(22/29)of specimens at the distal extensor retinaculum whereas EIP had a greater circumference in only 31%(9/29)of specimens at the MCP joint.CONCLUSION The EIP tendon is frequently ulnar to and greater in circumference than the EDCI at the distal extensor retinaculum,which can be taken into consideration for tendon transfers involving EIP.

Motor Response of Mirror Therapy after Reconstruction of Extensor Mechanism Caused by Glass Cut Injury

Treatment by mirror therapy (MT) restores motion in injured limbs without invasive procedures. This process is widely accepted for rehabilitating patients with phantom limb pain, stroke victims, or patients who need therapy after nerve damage. The procedure is specifically useful in restoring motion to the hand after surgical repairs to the extensor muscle and tendons. Mirror therapy rewires the brain by making the restored limb remember hand motions by observing the motions of a normal hand. The concept of a mirror image is that the movement of the uninjured arm forms the illusion of the same movement in the affected arm. Efforts to repeat hand movements elicit the same reaction in the affected hand in what is referred to as Hebbian learning. This case study evaluated MT’s effectiveness in motion restoration after a glass injury. This case study showed restoration of normal hand motions in a patient following surgery to repair a glass cut to the arm. Surgery repaired the lacerated extensor tendon and radial nerve. The muscle belly was repaired, and a graft fixed the nerve gap. Once the arm healed, the patient underwent rehabilitation in mirror therapy to restore normal function in his hand. After conducting mirror therapy, the pain was eliminated, and the patient restored normal function of moving the hand and finger extension. In addition, the therapy could be conducted at home without needing a professional. The effectiveness of mirror therapy was seen in the functional restoration of hand and finger movement. The process is also less complicated as it can be performed at home.

Ewings sarcoma of patella:A rare entity treated with a novel technique of extensor mechanism reconstruction using tendoachilles auto graft

We report a case of Ewings sarcoma(ES) involving the patella in a young female. ES of patella is a rare entity. The patient was presented with anterior knee pain and swelling arising from the patella. She was treated with neoadjuvant chemotherapy followed by wide excision of the patella and reconstruction of the extensor mechanism using split tendoachilles auto graft. The patella is an uncommon site for primary or metastatic tumors of the bone. ES, though rare, should be included in the differential diagnosis of swellings arising from the patella. Auto graft from the tendoachilles is a good alternative for reconstructing the extensor mechanism of the knee.

Extensor pollicis brevis tendon can hyperextend thumb interphalangeal joint in absence of extensor pollicis longus:Case report and review of the literature

We are reporting a case of extensor pollicis longus tendon rupture which did not require tendon transfer owing to the ability of the intact extensor pollicis brevis(EPB) to fully hyperextend the thumb interphalangeal joint. The thumb metacarpophalangeal joint was also able to be fully actively extended by the EPB. Previous anatomical studies have demonstrated that the insertional anatomy of the EPB tendon is highly variable and sometimes inserts onto the extensor hood and distal phalanx, which is likely the mechanism by which our patient was able to fully extend the thumb interphalangeal joint. Despite the potential for the EPB to extend the IP joint of the thumb, virtually all previously reported cases of extensor pollicis longus(EPL) tendon rupture had deficits of thumb IP extension requiring tendon transfer. This case highlights the potential ability of the EPB tendon to completely substitute for the function of the EPL tendon in providing thumb IP joint extension.

Traumatic Closed Floating Kneecap: Clinical Case about Traumatic Bipolar Tendon Rupture of Extensor Knee System

The simultaneous traumatic rupture of the patellar tendon and the quadricipital tendon is a rare lesion entity. We report the case of a bipolar rupture of the extensor knee system in a young adult following sports traumatism. Magnetic Resonance Imaging allowed the assessment of associated lesions. The management of this “floating” kneecap was surgical associated with rehabilitation. A functional assessment at 02 years of follow-up was performed. The functional prognosis is related on the one hand to the difficulties of positioning of the patella and on the other hand to the associated lesions (meniscus-ligamentous knee injuries).

A Case of Muscle Contraction-Induced Ischemic Limb Hyperemia in a Patient with Peripheral Arterial Disease during Incremental Repeat Isometric Knee Extensor Workloads

Background: To determine whether muscle contraction-induced leg blood flow (LBF) during exercise may be altered in a patient with an ischemic limb due to peripheral arterial disease (PAD) compared with the non-PAD limb. Case Presentation: A 66-year-old male patient with intermittent claudication due to PAD in the right leg (ankle brachial pressure index, 0.69) showed complete obstruction in both common iliac arteries including internal/external segments with collaterals above the femoral artery and popliteal artery with collaterals, and in the healthy left non-PAD-leg (1.06). He attempted unilateral repeat isometric knee extensions at a target contraction rhythm with each leg at incremental contraction intensities (5%, 10%, and 30% of maximum voluntary contraction [MVC] for 3 min at each intensity). Blood velocity/flow (Doppler ultrasound) in the femoral artery, blood pressure, and leg vascular conductance (LVC) were measured. Isometric thigh MVC strength pre-exercise was similar between the PAD-leg (48.0 kg) and non-PAD-leg (48.7 kg). Pre-exercise LBF (ml/min) was also similar between the PAD-leg (316) and non-PAD-leg (327). Blood pressure increases were similar during exercise. Average exercising LBF in ml/min in the last 1 min at each intensity was higher in the PAD-leg than the non-PAD-leg: 1087 vs. 471 at 5%, 2097 vs. 712 at 10%, and 2656 vs. 1517 at 30% MVC with a close positive linear relationship between LBF and %MVC in the non-PAD-leg (r = 0.999, P < 0.01), in agreement with previous findings, but less significant in the PAD-leg (r = 0.879, P = NS), indicating intense vasodilation (increasing LVC) in the PAD-leg compared with the non-PAD-leg. Conclusion: Knee extensor exercising LBF in the femoral artery was dissimilar between the PAD-leg and non-PAD-leg at the same exercise intensity, even though pre-exercising LBF was the same. Further research on the time-course in hemodynamics during leg exercise in PAD might potentially provide insight for the cardiovascular adjustment in severity of arteriosclerosis, stenosis and/or collaterals reserve.

Transfer of the extensor indicis proprius branch of posterior interosseous nerve to reconstruct ulnar nerve and median nerve injured proximally:an anatomical study

Proximal or middle lesions of the ulnar or median nerves are responsible for extensive loss of hand motor function.This occurs even when the most meticulous microsurgical techniques or nerve grafts are used.Previous studies had proposed that nerve transfer was more effective than nerve grafting for nerve repair.Our hypothesis is that transfer of the posterior interosseous nerve,which contains mainly motor fibers,to the ulnar or median nerve can innervate the intrinsic muscles of hands.The present study sought to investigate the feasibility of reconstruction of the deep branch of the ulnar nerve and the thenar branch of median nerve by transferring the extensor indicis proprius branch of the posterior interosseous nerve obtained from adult cadavers.The results suggested that the extensor indicis proprius branch of the posterior interosseous nerve had approximately similar diameters and number of fascicles and myelinated nerve fibers to those of the deep branch of ulnar nerve and the thenar branch of the median nerve.These confirm the feasibility of extensor indicis proprius branch of posterior interosseous nerve transfer for reconstruction of the deep branch of the ulnar nerve and the thenar branch of median nerve.This procedure could be a novel and effective method for the functional recovery of the intrinsic muscles of hands after ulnar nerve or median nerve injury.

The Effect of Deep Friction Massage versus Stretching of Wrist Extensor Muscles in the Treatment of Patients with Tennis Elbow

Overuse injuries of the elbow and forearm are very common in athletes. This study was conducted to evaluate the effect of muscle stretching and deep friction massage with using wrist joint support during management of tennis elbow. This study included forty patients with tennis elbow divided into two equal groups: the first group with a mean age 38.1 ± 0.294 followed a physical therapy program in form of deep friction massage on the proximal attachment of wrist extensor muscles, the second group with a mean age 37.6 ± 0.253, submitted to stretching exercises of wrist extensors. Both of groups submitted to ultrasonic therapy with wrist splint during treatment period, three sessions per week for six weeks. Outcome measures were universal goniometer, visual analogue scale, and squeezing sphygmomanometer. The results showed that there was a significant improvement in ROM of wrist flexion and wrist extension, and handgrip in second group and it was more than in the first group while no significant difference in pain. This study showed that stretching exercise is more beneficial in the management of patients with tennis elbow.

Reliability Study on Quantitative Detection of Extensor Digi- torum Brevis Strength with Needle Electromyography and Nerve Conduction

Objective To study the objectivity and reliability of needle electromyography and nerve conduction for detection of musculus extensor digitorum brevis strength, which may provide a basis for establishing a quantitative detection of muscle strength in forensic clinical study. Methods Forty-four healthy people were enrolled as the subjects, and during toe dorsiflexion, the following items including needle electromyography indexes, motor unit potential(MUP) amplitude, MUP count, recruitment reaction type, and nerve conduction detection indexes, compound muscle action potential(CMAP) amplitude, CMAP latent period and motor nerve conduction velocity(MNCV), were simultaneously detected under the cooperation and disguise condition. Results Under the cooperation condition, regardless of the same operator or different operators, there were good test-retest reliabilities in MUP amplitude, CMAP amplitude, CMAP latent period and MNCV, while there were normal test-retest reliabilities in MUP count and recruitment reaction type and the repeatability of the same operator was slightly better than the repeatability between different operators. Under the disguise condition, test-retest reliabilities of MUP amplitude, CMAP amplitude, CMAP latent period and MNCV were relatively high, while test-retest reliabilities of MUP count and recruitment reaction type were relatively low. Conclusion There are good test-retest reliabilities in MUP amplitude, CMAP amplitude, CMAP latent period and MNCV, which can be conducive to comparison between different operators and results at various times; MUP count and recruitment reaction type, which can be easily affected by subjectivity of operators and examinees, can be used to differentiate whether an examinee disguises or not. The indexes used to objectively judge muscle strength remain to be further investigated.

目的:应用表面肌电图观察和分析膝骨关节炎(knee osteoarthritis,KOA)患者股四头肌表面肌电活动。方法:采用全无线肌电测试系统评测30例KOA患者(KOA组)和30例健康受试者(CON组)在不同角速度(60°/s、90°/s、180°/s)膝关节屈伸运动等速肌力测试下,股内侧肌、股直肌和股外侧肌的表面肌电图,并记录KOA组受试者股内侧肌、股直肌和股外侧肌肌肉厚度与膝痛程度,以评估肌电数据和临床指标的相关性。结果:KOA患者和健康受试者在各不同角速度60°/s(P<0.001)、90°/s(P<0.01)、180°/s(P<0.01)膝关节屈伸运动中屈膝最大力矩与伸膝最大力矩均具有显著性意义,且KOA组膝关节屈伸最大力矩平均值均低于CON组。在角速度为60°/s等速肌力测试时,KOA组股外侧肌的中值频率差值率(P<0.05)、股直肌的均方根值(P<0.01)与相应对照组具有显著性意义;在角速度为90°/s等速肌力测试时,两组受试者的股直肌均方根值存在显著性差异(P<0.05);在角速度为180°/s时,两组的股直肌中值频率差值率(P<0.05)和均方根值(P<0.05)存在显著性差异。在多元线性回归与基于随机森林算法的数据回归分析中,无论是肌肉厚度还是膝痛程度,与临床指标关系最显著的肌电特征均为伸膝运动时的最大力矩。结论:KOA患者股四头肌肌力下降,需要更多的肌肉协同收缩才能完成动作,容易造成肌肉疲劳。伸膝力矩与股四头肌肌肉厚度和膝周疼痛密切相关,有望作为KOA诊断的重要指标。

Single-fiber Electromyography in the Extensor Digitorum Communis for the Predictive Prognosis of Ocular Myasthenia Gravis： A Retrospective Study of 102 Cases

Background： Single-fiber electromyography （SFEMG） abnormality in the extensor digitorum communis （EDC） was reported in ocular myasthenia gravis （OMG）, which indicated subclinical involvement beyond extraocular muscles in OMG patients. The relationship between the abnormal findings of SFEMG in EDC and the probability for OMG to develop generalized myasthenia gravis （GMG） is unknown, This retrospective study aimed to determine the predictive value of abnormality of SFEMG in EDC of OMG patients. Methods： One-hundred and two OMG patients underwent standard clinical diagnosis process and SFEMG test in EDC muscle when diagnosed and were clinically followed up for 5 years. The SFEMG data were compared between different clinical groups according to thymus status, onset age, and different outcome of OMG developing. Chances of progressing to GMG were compared between two different groups according to SFEMG and repetitive nerve stimulation （RNS） results, acetylcholine receptor antibody （AchRAb） titer, thymus status, and onset age. Results： Abnormal SFEMG results were observed in 84 （82.4%） patients. The mean jitter, percentage of jitter 〉55 Its （%）, and blocking were higher in OMG patients than in healthy volunteers. There were no statistical differences in jitter analysis between thymoma group and non-thymoma group （P = 0.65）, or between the later OMG group and the later GMG group （P = 0.31）, including mean jitter, percentage of jitter 〉55 Its （%）, and blocking. Elderly group （〉45 years old） had a higher mean jitter than younger group （t = 2.235, P = 0.028）. Total 55 OMG developed GMG, including 47 in abnormal SFEMG group while 8 in normal SFEMG group. There was no statistical difference in the conversion rates between the two groups （x^2 = 0.790, P = 0.140）. RNS abnormality, AchRab titer, or onset age had no correlation with OMG prognosis （P = 0.150, 0.070, 0.120, respectively） while thymoma did （x^2 = 0.510, P = 0.020）. Conclusion： SFEMG test in the EDC showed high abnormality in OMG, suggesting subclinical involvement other than extraocular muscles. Nevertheless, the abnormal jitter analysis did not predict the prognosis of OMG according to clinical follow-up.

重复外周磁刺激作用于上肢不同位置对亚急性期脑卒中患者腕关节运动功能的影响:一项随机对照试验

背景腕关节运动功能障碍是脑卒中后常见遗留症,而腕关节在提高手部实用性方面具有重要作用。因此,提高患者的腕关节运动能力可以有效地促进其日常生活参与度,尽管重复外周磁刺激(rPMS)已被证明对改善该问题具有显著效果,但针对不同位点的治疗效果仍需深入探究。目的探索rPMS分别作用于伸腕肌、桡神经时对亚急性期脑卒中患者腕关节运动功能的影响。方法选取2022年10月—2023年10月在福建中医药大学附属康复医院住院治疗且存在腕关节运动功能障碍的亚急性期脑卒中患者60例作为研究对象。采用随机数字表法将患者分为对照组(20例)、肌肉刺激组(20例)和神经刺激组(20例),对照组接受常规的康复训练,肌肉刺激组和神经刺激组分别在对照组的治疗方案上增加rPMS,且分别作用于伸腕肌和桡神经上,于干预前、后(10次治疗)分别采集伸腕肌表面肌电的积分肌电值(iEMG)、均方根植(RMS)和中位频率(MF),Fugl-Meyer评定量表上肢部分(FMA-UE)、手臂动作调查测试(ARAT)、改良Barthel指数(MBI)进行患侧上肢功能评估。结果干预期间由于主动要求退出试验、被迫终止试验等原因导致数据丢失2例,最终纳入对照组20例、肌肉刺激组19例、神经刺激组19例。治疗前三组患者伸腕肌表面肌电的iEMG、RMS、MF比较,差异无统计学意义(P>0.05)。治疗后肌肉刺激组、神经刺激组患者伸腕肌表面肌电的iEMG、RMS、MF高于对照组(P<0.05);神经刺激组患者伸腕肌表面肌电的iEMG、RMS、MF高于肌肉刺激组(P<0.05)。三组患者治疗后伸腕肌表面肌电的iEMG、RMS、MF均高于组内治疗前(P<0.05)。治疗前三组患者FMA-UE、ARAT、MBI评分比较,差异无统计学意义(P>0.05);治疗后肌肉刺激组、神经刺激组患者FMA-UE、ARAT、MBI评分高于对照组(P<0.05);神经刺激组患者FMA-UE、ARAT、MBI评分高于肌肉刺激组(P<0.05)。三组患者治疗后FMA-UE、ARAT、MBI评分均高于组内治疗前(P<0.05)。结论rPMS分别作用于伸腕肌、桡神经,对脑卒中后腕关节运动功能障碍均有改善,且作用于桡神经较伸腕肌疗效更显著。

Optimization design of extensor for improving locomotion efficiency of inchworm-like capsule robot

An inchworm-like capsule robot(ILCR) is a promising device for a minimally invasive diagnosis and treatment of colon diseases. It consists of two expanders and one extensor, the former provides a traction force by expanding the colon and the latter can elongate and retract to enable active locomotion. However, the locomotion efficiency of the ILCR can be seriously lowered by the complex colon environment featuring slippery, viscoelastic, and suspend properties, which has been a main obstacle to its clinical application. This paper aims at improving the locomotion efficiency of the ILCR by optimizing its extensor design. To do this, the locomotion resistance of the ILCR in the colon is analyzed, and complying with a requirement that the traction force must be larger than the locomotion resistance to avoid slipping, a restriction on the extensor design is obtained. Then under the restriction and with reference to the Hyperelastic model which correlates stress and strain of colon tissue, a model for analyzing the influence of the design parameters of the extensor on the locomotion efficiency of the ILCR is built. With this model, the extensor has been optimized and the optimized results have been used to guide the development of a novel extensor, which employs two pairs of lead-screws and nuts and is actuated by one motor. Ex-vivo experiment has shown that the novel extensor can improve the locomotion efficiency of an ILCR prototype by 57%, without changing its total length.

颈前路椎间盘切除减压植骨融合术后患者颈长肌和颈伸肌的影像观察

目的观察脊髓型颈椎病患者接受颈前路椎间盘切除减压植骨融合术(anterior cervical discectomy and fusion,ACDF)术后的颈长肌和颈伸肌变化情况,并分析颈长肌和颈伸肌的术后变化与ACDF手术疗效的相关性。方法以该科2016年6月~2021年6月开展单节段ACDF手术的62例脊髓型颈椎病患者作为研究对象,分别于术前、术后3个月、术后1年和末次随访时,进行VAS评分、mJOA评分和NDI指数等疗效指标评价;同时,采用颈椎MRI T2加权像检查并测量其颈长肌和颈伸肌的横截面积(cross section area,CSA),颈长肌的最长径/最短径比值(ratio of long and short lines,RLS)以及颈长肌和颈伸肌的容积。采用Pearson相关性系数对颈长肌和颈伸肌容积与上述疗效指标进行相关性分析。结果62例患者均成功完成单节段ACDF手术且获访24~30个月、平均25.9个月。与术前相比,患者术后3个月、1年和末次随访时的颈肩痛VAS评分、mJOA评分和NDI指数均显著改善(P<0.05)。末次随访时采用Odom标准评价,优38例,良22例,可2例。与术前相比,所有患者术后3个月、1年和末次随访时的颈长肌CSA和颈长肌容积均显著减少(P<0.05),术后3个月、1年和末次随访时的颈长肌RLS均显著增加(P<0.05);颈伸肌CSA和颈伸肌容积在手术前和术后各时间的变化无显著性差异(P>0.05)。经Pearson相关性分析显示,术后3个月、术后1年和末次随访的颈长肌容积与同时期的VAS评分和NDI指数均呈负相关性(P<0.05),与mJOA评分无明确相关性(P>0.05);而颈伸肌容积与同时期的VAS评分、NDI指数和mJOA评分均无明确的相关性(P>0.05)。结论脊髓型颈椎病患者行ACDF手术后,颈长肌可出现一定程度退变,颈伸肌的退变并不显著。颈长肌的退变可对手术预后产生不利影响。

观察掌长肌腱移植与示指固有伸肌腱转位治疗拇长伸肌腱自发性断裂疾病的效果

目的比较拇长伸肌腱自发性断裂疾病应用掌长肌腱移植和示指固有伸肌腱转位治疗的效果。方法选取胶州市中医医院于2021年7月—2023年7月收治的60例拇长伸肌腱自发性断裂患者作为研究对象,依照两组患者手术方式的不同分为一组(掌长肌腱移植治疗),二组(示指固有伸肌腱转位治疗),各30例,对治疗效果和手功能指标展开对比。结果一组优良率为90.00%,二组优良率为86.67%,两组患者优良率对比,差异无统计学意义(P>0.05);两组患者手指功能指标(整体功能、日常生活能力、工作表现、自我满意度、疼痛评分)对比,差异无统计学意义(P均>0.05)。结论在治疗拇长伸肌腱自发性断裂患者时,示指固有伸肌腱转位治疗和掌长肌腱移植都为常见术式、有效术式,两种方法取得的临床效果均良好,要结合患者的病情以及个人意愿酌情选择术式。
