Restoration Of Hand Function Research Articles

Clinical utility of extracorporeal shock wave therapy in restoring hand function of patients with nerve injury and hypertrophic scars due to burns: A prospective, randomized, double-blinded study.

Joint contractures and nerve injuries are common after hand burns. Extracorporeal shock wave therapy (ESWT) is effective not only for the regeneration of various tissues, including scar tissues, but also for reducing pain and pruritus in patients with burns. Researchers have attempted to explore the effects of ESWT on hand dysfunction caused by nerve injury following burns. We evaluated the effects of ESWT (compared to sham stimulation) on hands with nerve injury and hypertrophic scars and thereby on hand function. The current study was a double-blind randomized controlled trial involving 120 patients. The ESWT parameters were as follows: energy flux density, 0.05-0.30mJ/mm2; frequency, 4Hz; 1000 to 3000 impulses per treatment; and 12 treatments, one/week for 12 weeks. Outcome measures were as follows: 10-point visual analog scale for pain, Jebsen-Taylor hand function test, grip strength, Purdue Pegboard test, ultrasound measurement of scar thickness, and skin characteristics before and immediately after 12 weeks of treatment. No significant inter-group difference was noted after the initial evaluation (P>0.05). More significant improvements were found in the ESWT group than in the sham group in terms of the VAS score (P=0.004), extension ROMs of hand joints (P=0.02), the JTT scores (writing, small, and light) (P<0.001, P<0.001, and P=0.002), and skin characteristics (melanin, skin distensibility, and biologic skin elasticity) (P=0.004, P<0.001, and P<0.001). Other measured outcomes did not differ between the two groups after the treatment. We identified the clinically beneficial effects of ESWT in promoting hand function, improving scarring, and alleviating scarring-related pain, thereby highlighting its advantages in improving hand function that has been impaired due to nerve injury and hypertrophic scars after burns.

DISTANT SOFT TISSUE FLAPS IN A DEGLOVING SKIN INJURY

Avulsion skin injuries of the glove removal type are one of the most challenging and difficult problems in reconstructive hand surgery. Immediate or early coverage of the hand is of utmost importance. Several options are proposed for early covering the preserved structures (tendons, bones and nerves) early, mainly skin grafting on the preserved viable structures. Case description: We present a case of a patient with 4th and 5th finger crushing and avulsion skin injury of thumb and index finger and lost distal phalanges. The 4th and 5th fingers had been amputated due to gangrene. Two anterior abdominal wall flaps were applied: a thoraco-umbilical flap and a horizontal Filatov stem" flap. On the 25th day, the flaps were separated from the fingers and following commissuroplasty 10 months later. Result: Fusion between the donor flap and the recipient structures was obtained without clinical evidence of infection, ulceration and flap necrosis. Conclusions: The usage of remote skin flaps is a safe and simple method to restore hand function when microsurgery cannot be applied.

Supinator to posterior interosseous nerve transfer to restore hand opening in brachial plexus and spinal cord injury: a systematic review and individual patient-data meta-analysis.

Cervical spinal cord injury (SCI) and lower trunk brachial plexus injury (BPI) commonly result in hand paralysis. Although restoring hand function is complex and challenging to achieve, regaining volitional hand control drastically enhances functionality for these patients. The authors aimed to systematically review the outcomes of hand-opening function after supinator to posterior interosseous nerve (PIN) transfer. A systematic literature review was performed according to the PRISMA guidelines. A total of 16 studies with 88 patients and 119 supinator to PIN transfers were included (87 transfers for SCI and 32 for BPI). In most studies, the time interval from injury to surgery was 6-12 months. Finger extension and thumb extension (Medical Research Council grade ≥ 3/5) recovered in 86.5% (103/119) and 78.1% (93/119) of cases, respectively, over a median follow-up of 19 months. The rates of recovery were similar for the SCI and BPI populations (finger extension, 87.3% in SCI and 84.3% in BPI; thumb extension, 75.8% in SCI and 84.3% in BPI). Type of injury (OR 1.05, 95% CI 0.17-6.4, p = 0.95), time from injury to surgery (OR 1.01, 95% CI 0.8-1.29, p = 0.88), and age (OR 0.97, 95% CI 0.90-1.06, p = 0.60) were not associated with odds of a successful outcome. Duration of follow-up was significantly associated with successful finger extension (OR 1.15, 95% CI 1.01-1.30, p = 0.026). No donor-associated supinator weakness was reported postoperatively given that patients had an intact bicep muscle preoperatively contributing to supination. Supinator to PIN transfer is a safe and effective procedure that can achieve successful restoration of digital extension in the SCI and BPI population at similar rates. Duration of follow-up was associated with superior outcomes, which was expected.

Сurrent medical rehabilitation methods for patients after carpal tunnel syndrome surgical treatment: a review

INTRODUCTION. Carpal tunnel syndrome is one of the most common tunnel syndromes types and ranks sixth in the all-occupational diseases’ registry. The high interest in this pathology and its’ postoperative management peculiarities study is due to the disease widespread prevalence, social significance, often unsatisfactory surgical treatment results and a long hand function restoration period. The purpose of this work was to study modern concepts of postoperative rehabilitation of patients with carpal tunnel syndrome. SOURCE SEARCH METHODOLOGY. When preparing the review, open electronic databases of scientific literature were used: PubMed, ClinicalTrials.gov, eLibrary.ru. The search for medical literature data was carried out using the following keywords: “rehabilitation”, “carpal tunnel syndrome”, “carpal tunnel syndrome”, “median nerve”, “compressive neuropathy”. The criteria for inclusion in the analysis of literature sources were: randomized controlled clinical trials, systematic reviews and meta-analyses. Preference was given to publications over the past 5–10 years. DISCUSSION. The article presents the most commonly used techniques in the postoperative management of patients with carpal tunnel syndrome, discusses the mechanisms of their action and prospects for the development of this area. The review discussed the following rehabilitation methods: a wide range of methods of hardware physiotherapy, manual therapy, kinesiotaping, manual lymphatic drainage, as well as the possibilities of physical therapy and robotic mechanotherapy. Despite the high level of development of medicine, the long process of rehabilitation of these patients remains an important problem, while the clinical effectiveness of a wider range of proposed techniques still remains poorly understood. Some of the most promising methods of rehabilitation of patients after surgical treatment for carpal tunnel syndrome are methods of robotic mechanotherapy and extracorporeal shock wave therapy. CONCLUSION. For the effective use of the described techniques as part of the postoperative rehabilitation of patients with carpal tunnel syndrome in clinical practice, further research and study of their long-term effects, as well as comparison of their effectiveness with the aim of the most complete and rapid restoration of the function of the affected hand, is necessary.

Evaluating the Ability of Brachial Plexus-Injured Patients to Control an Externally Powered (Myoelectric) Hand Prosthesis.

Restoration of hand function after traumatic brachial plexus injury (BPI) remains a formidable challenge. Traditional methods such as nerve or free muscle transfers yield suboptimal results. Advancements in myoelectric prostheses, characterized by novel signal acquisition and improved material technology, show promise in restoring functional grasp. This study evaluated the ability of adults with a BPI injury to control an externally powered prosthetic hand using nonintuitive signals, simulating the restoration of grasp with a myoelectric prosthesis. It also assessed the effectiveness of a comprehensive multidisciplinary evaluation in guiding treatment decisions. A multidisciplinary brachial plexus team assessed adults with compromised hand function due to BPI. The feasibility of amputation coupled with fitting of a myoelectric prosthesis for grasp reconstruction was evaluated. Participants' ability to control a virtual or model prosthetic hand using surface electromyography (EMG) as well as with contralateral shoulder motion-activated linear transducer signals was tested. The patient's input and injury type, along with the information from the prosthetic evaluation, were used to determine the reconstructive plan. The study also reviewed the number of participants opting for amputation and a myoelectric prosthetic hand for grasp restoration, and a follow-up survey was conducted to assess the impact of the initial evaluation on decision-making. Of 58 subjects evaluated, 47 (81%) had pan-plexus BPI and 42 (72%) received their initial assessment within 1 year post-injury. Forty-seven patients (81%) could control the virtual or model prosthetic hand using nonintuitive surface EMG signals, and all 58 could control it with contralateral uniscapular motion via a linear transducer and harness. Thirty patients (52%) chose and pursued amputation, and 20 (34%) actively used a myoelectric prosthesis for grasp. The initial evaluation was informative and beneficial for the majority of the patients, especially in demonstrating the functionality of the myoelectric prosthesis. The study indicates that adults with traumatic BPI can effectively operate a virtual or model myoelectric prosthesis using nonintuitive control signals. The simulation and multidisciplinary evaluation influenced informed treatment choices, with a high percentage of patients continuing to use the myoelectric prostheses post-amputation, highlighting its long-term acceptance and viability.

SUTURE CHOICE IN CARPAL TUNNEL SURGERY: A RANDOMIZED CONTROLLED TRIAL

ObjectiveCarpal tunnel release surgery is a commonly performed procedure for alleviating symptoms of median nerve compression and restoring hand function. With pressure on theatre time these procedures are now commonly performed in a step-down out-patient facility under local anaesthetic. The choice of suture for skin closure in this procedure can impact the quality of wound healing, patient outcomes and the follow-up required however the question of the best type of suture remains unanswered. The purpose of this study was to compare the outcomes of absorbable and non-absorbable sutures using a randomised control trial design.MethodsEighty patients diagnosed with bilateral carpal tunnel syndrome were enrolled and underwent outpatient carpal tunnel release surgery under local anaesthetic in a staged fashion. Random number generation was used to assign each hand to receive interrupted nylon or Vicryl Rapide sutures. Pre-operative data collection included patient demographics, ASA, inflammatory conditions, smoking status as well as a Boston Carpal Tunnel Questionnaire (BCTQ) for each hand. Patients were followed up at 2 and 6 weeks after each operation and the BCTQ was repeated along with the Patient and Observer Scar Assessment Scale and the VAS score for wound discomfort. This study has approval from the DHB ethics committee, Local Iwi, HDC and ANZ Clinical Trials:ACTRN12623000100695.ResultsStatistical analysis assessed patient preference and the scores between the groups. Multi-variate analysis was performed to assess the factors that may be contributing to patient choice.ConclusionInsights into patient preference and clinical outcomes associated with absorbable sutures and non-absorbable sutures in the setting of out-patient surgery are discussed.

Deep burn surgery of the whole dorsum of the hand: Composite skin grafting over acellular dermal matrix versus thick split-thickness skin grafting.

Preservation and restoration of hand function after burn injuries are challenging yet imperative. This study aimed to assess the curative effect of a composite skin graft over an acellular dermal matrix (ADM) and a thick split-thickness skin graft (STSG) for treating deep burns on the hand. Patients who met the inclusion criteria at the First Affiliated Hospital of Wenzhou Medical University between September 2011 and January 2020 were retrospectively identified from the operative register. We investigated patient characteristics, time from operation to the start of active motion exercise, take rates of skin graft 7 days post-surgery, donor site recovery, complications and days to complete healing. Patients were followed up for 12 months to evaluate scar quality using the Vancouver Scar Scale (VSS) and hand function through total active motion (TAM) and the Jebsen-Taylor Hand Function Test (JTHFT). A total of 38 patients (52 hands) who received thin STSG on top of the ADM or thick STSG were included. The location of the donor sites was significantly different between Group A (thick STSG) and Group B (thin STSG + ADM) (p = 0.03). There were no statistical differences in age, gender, underlying disease, cause of burn, burn area, dominant hand, patients with two hands operated on and time from burn to surgery between the two groups (p > 0.05). The time from operation to the start of active motion exercise, take rates of skin graft 7 days post-surgery and days to complete healing were not significantly different between Group A and Group B (p > 0.05). The rate of donor sites requiring skin grafting was lower in Group B than in Group A (22.2% vs. 100%, p < 0.001). There were no statistically significant differences in complications between the groups (p = 0.12). Moreover, 12 months postoperatively, the pliability subscore in the VSS was significantly lower in Group A than in Group B (p = 0.01). However, there were no statistically significant differences in vascularity (p = 0.42), pigmentation (p = 0.31) and height subscores (p = 0.13). The TAM and JTHFT results revealed no statistically significant differences between the two groups (p = 0.22 and 0.06, respectively). The ADM combined with thin STSG is a valuable approach for treating deep and extensive hand burns with low donor site morbidity. It has a good appearance and function in patients with hand burns, especially in patients with limited donor sites.

Osteoplastic Reconstruction of the Thumb: a case report

Background &amp; Objectives: Thumb accounts for 50% of the hand function. Amputation of the thumb severely jeopardises the hand function. Thumb replantation, toe transfer are the ideal methods for restoring the hand function, but is not always possible owing to type of injury, time to presentation, surgical skill and set up. Osteoplastic thumb reconstruction for amputation around the metacarpophalangeal joint is a good treatment option to restore the hand in a developing setup. Presentation of Case: A 25 yrs male with amputation of thumb around metacarpophalangeal joint with delayed presentation and crushing component of distal part underwent multiple staged osteoplastic reconstruction of the thumb. The procedures consisted of bony structure fixation with bone graft followed by coverage with a thinned tubed groin flap which was divided at 2 weeks interval. The thumb was made sensate with sensate flap (first dorsal metacarpal artery flap). Discussion: Thumb replantation is ideal in acute setup in a clean traumatic amputation, while toe transfer is ideal in a delayed setup with healed wound. This requires a good operating room set up with microsurgical set up and skilled manpower, which is difficult in a developing country. Osteoplastic reconstruction requires multiple staged procedures that can be done at a primary level setup. Conclusion: Osteoplastic thumb recontruction is a good option for amputation around the metacarpophalangeal joint to restore hand function in a resource limited set up.

Machine learning for hand pose classification from phasic and tonic EMG signals during bimanual activities in virtual reality.

Myoelectric prostheses have recently shown significant promise for restoring hand function in individuals with upper limb loss or deficiencies, driven by advances in machine learning and increasingly accessible bioelectrical signal acquisition devices. Here, we first introduce and validate a novel experimental paradigm using a virtual reality headset equipped with hand-tracking capabilities to facilitate the recordings of synchronized EMG signals and hand pose estimation. Using both the phasic and tonic EMG components of data acquired through the proposed paradigm, we compare hand gesture classification pipelines based on standard signal processing features, convolutional neural networks, and covariance matrices with Riemannian geometry computed from raw or xDAWN-filtered EMG signals. We demonstrate the performance of the latter for gesture classification using EMG signals. We further hypothesize that introducing physiological knowledge in machine learning models will enhance their performances, leading to better myoelectric prosthesis control. We demonstrate the potential of this approach by using the neurophysiological integration of the "move command" to better separate the phasic and tonic components of the EMG signals, significantly improving the performance of sustained posture recognition. These results pave the way for the development of new cutting-edge machine learning techniques, likely refined by neurophysiology, that will further improve the decoding of real-time natural gestures and, ultimately, the control of myoelectric prostheses.

Efficacy of 3D Printed Finger Prosthesis for patients affected with Hansen’s Disease to Restore Hand Function

Introduction The greek word LEPROSY was renamed by the term Hansen’s disease by Norwegian physician Gerhard Armauer Hansen. In 2009, WHO Goodwill Ambassador Yohei Sasakawa called for an end to usage of the word leprosy, since he described it as ‘an extremely damaging term’ that contributes to stigma and impacts human rights. Since 2010, leprosy mission gives assurance that the word is not condoned by media channels or used by public figures. HD ranges from mild to severe (based on one or more skin areas affected and damage caused to organs).There were 5.2 million people affected by leprosy globally, in 1980 but by 2020 this decreased to fewer than 2,00,000. Leprosy can affect people in many ways. The Cochrane database of systemic reviews , 2019 lists that 30% of people affected with leprosy experience nerve damage. People with untreated leprosy become visibly disfigured often have psychologic and social problems. Mosby’s Medical Dictionary 2009 defines trophic ulcers as “a pressure ulcer caused by external trauma to a part of body or by vascular insufficiency leading to loss of afferent nerve fibres. The most severe complications result from infection of the peripheral nerves, which causes deterioration of sense of touch and inability to feel pain and temperature. The nerve damage is reversible when treated early, but becomes permanent when appropriate treatment is not available for sufferer. Damage to nerves may cause loss of muscle function, leading to paralysis. It may also lead to sensation abnormalities or numbness, which may lead to additional infections, ulcerations, and joint deformities. Also, damage to peripheral nerves may cause muscle weakness that can result in deformities. M. leprae attacks nerve endings and destroys the body's ability to feel pain and injury. Without feeling pain, people with leprosy have an increased risk of injuring themselves. In some cases, autoamputation has been reported to affect the tip of fingers. People with peripheral nerve damage may unknowingly burn, cut, or otherwise harm themselves. Infected nerves may enlarge also &amp; this can be palpated. The fingers may be weakened, causing them to curve inward (claw hand). When therapeutic amputation is decided for a patient affected with HD, occupational therapist can suggest preserving as much of hand as possible, to prepare wearing 3D printed prosthesis. 3-D printing is a new rising technology, Objects made in 3D printing range from plastic figurines and mould patterns to steel machine parts and titanium surgical implants. Related to Hansen Disease, It facilitates manufacturing hand parts with irregular and uncommon geometric shapes. Freedom offered by 3D printing techniques has paved the way for the application of new design for best appearances. The advantages of 3D printing could be used to fabricate prosthetic hands based on the biological design principles. The purpose of this study is to assess efficacy of 3-D printed finger prosthesis to manipulate objects &amp; to restore hand function in HD clients.

Outcome of Transfer Flexor Carpi Ulnaris And Plmaris Longus Tendons for Hand Deformity in Persistance Radial Nerve Palsy

Objective; the aim of our study is to evaluate the functional outcome of transfer flexor carpi ulnaris and palmaris longus for patients with persistence radial nerve palsy by minimal tendon transfer technique.&#x0D; Methods; The study included 10 patients 8 male and two female, mean age 25 years, range from 20 to 30 years. They underwent transfer of flexor carpi ulnaris (FCU) and palmaris longus (PL) tendon for patient with persistence radial nerve palsy, the duration of outcome of tendon transfer after radial nerve injury evaluated after one year. Clinical evaluation include wrist joint range of movement by Geniometry and compared with the contralateral normal side.&#x0D; Results; The average ranges of wrist movements were as the follows: the mean wrist flexion was 52⁰(range 46⁰–56⁰), the mean wrist extension was 34⁰(range 30–38), radial deviation 18⁰(range 16⁰–20⁰) and ulnar deviation 21⁰ (range 18–23). The mean extension of the fingers in wrist extension was 7⁰(range 5⁰–10⁰) and in wrist neutral position was 12⁰(range 9⁰–16⁰). The mean abduction of the thumb was 38⁰(range 35⁰–44⁰). In comparison to the measure of joints in the contralateral normal hand, the final extension of the wrist was less, but extension of the fingers and MCP joints was similar to that of the normal hand. All of the patients in our study were able to extend their fingers with the wrist in the neutral position. Thumb abduction and extension was sufficient to deal with daily activities and, even, heavy jobs in most of the patients. Postoperative follow up of the patients was ranged (12–24) months. After 45 days, 8o% of the patients were able to do the normal non heavy daily work. In 20% of cases recovery was not progressing satisfactorily at 5 weeks. These were referred to physiotherapy for a planned exercise program, which the two patients improved their movements.&#x0D; Conclusion; The purpose of this study was to evaluate function of the hand after transfer of the FCU to EDC and PL to EPL, with persistence high nerve injuries. The FCU &amp; PL tendons transfer has some advantages over the other techniques, short duration of operation time, no morbidity, improve range of motion of hand and less surgical scares. It is a viable option to restore hand function and strength following radial nerve injuries.

ОДНОЭТАПНАЯ КОРРЕКЦИЯ ПОСЛЕДСТВИЙ ПОВРЕЖДЕНИЯ ЛОКТЕВОГО НЕРВА

Objective: : To enhance the outcomes of surgical treatment for chronic ulnar nerve injuries by performing one-stage correction. Methods: From 2015 to 2023, 11 patients with chronic ulnar neurovascular bundle (NVB) injuries underwent one-stage reconstruction to restore hand function. The operations were performed on 8 men and 3 women aged 16 to 23. The duration of treatment for patients from the time of injury varied from 1.2 years to 5 years Results: In cases where there was a diastasis between the neural ends of no more than 3 cm in the upper third of the forearm due to nerve damage, restoration of the nerve with epineural suture was performed in 2 patients, while in two other cases with more significant gaps of 3.5 and 5 cm, epineural repair was carried out after anterior transposition of the nerve trunk. In one case of nerve damage in the middle third of the forearm, epineural sutures were applied to a 2.5 cm gap. Among 6 patients with damage to the ulnar NVB in the lower third of the forearm, 4 received epineural restoration of the ulnar nerve, and autologous neuroplasty was performed in gaps exceeding 3 cm in 2 patients. In cases of damage to the ulnar artery, 3 patients received autologous vein grafting, while in 3 other cases, there were no indications for vascular reconstruction. No infectious or inflammatory complications were observed in the immediate postoperative period, and there were no cases of thrombosis of autologous vein grafts of the ulnar artery. After evaluating all patients for 6 months to 2 years, it was found that 9 cases showed favorable and satisfactory long-term functional outcomes, while 2 cases exhibited unsatisfactory results. Conclusion: Restoring hand function after damage to the ulnar nerve is greatly influenced by the location, extent, and type of the damage, as well as the choice of an appropriate reconstruction method. Breaking the procedure into multiple stages can prolong patient recovery and negatively impact treatment outcomes. Conversely, performing the operation in a single stage within a relatively short timeframe can restore hand function and significantly reduce overall treatment and rehabilitation time Keywords: Ulnar nerve, neurovascular bundle, injury, tendon-muscular transfer, epineural suture

Сlinical experience with the modified rehabilitation protocol after trapeziometa- carpal joint resection suspension interposition autotendoplasty.

Aim. The aim of this study is to assess the effectiveness of a modified postoperative rehabilitation protocol in patients who underwent their first carpometacarpal joint resection suspension interposition autotendoplasty.Materials and Methods. The study included 52 patients treated for trapeziometacarpal joint osteoarthritis stage II—IV according to the Eaton-Littler and Kellgren-Lawrence classification in the Upper Limbs Surgery Department of the Bauman City Clinical Hospital from 2017 to 2022. All patients underwent trapeziometacarpal joint resection suspension interposition autotendoplasty and a course of rehabilitation. The evaluation of surgical treatment and rehabilitation results was carried out based on indicators on the VAS, DASH, and hand grip strength scales 12 months after surgery.Results. The complex treatment resulted in the complete restoration of hand function. Twelve months after surgery, there was a significant improvement in hand functional parameters. According to the DASH scale, the improvement was 80 % compared to the preoperative level (p = 0.000). The pain syndrome, according to the VAS scale, decreased by 84 % from the baseline (p = 0.000). Affected hand grip strength reached its maximum value of 26.2 kg, exceeding the preoperative level by 67 % (p = 0.006).Conclusion. The modified rehabilitation protocol used after performing trapeziometacarpal joint resection suspension interposition autotendoplasty in clinical practice enabled the full restoration of affected hand function.

Osteoid-osteoma of trapezium bone in a child (clinical case)

BACKGROUND: Osteoid osteoma is a benign neoplasm of bones with a diameter of up to 1.5 cm. It is most common in children in the second decade of life and at the age of 20–30 years, predominantly in men. In large neoplasms (1.5 cm) with a histological study identical to osteoid osteoma, the pathological process is regarded as osteoblastoma or giant osteoid osteoma. The tumor is most often located in long tubular bones and on the hand in 5%–15% of the patients. Differential diagnosis is carried out with rheumatoid arthritis, inflammation, and other neoplasms. Various options for the treatment of osteoid osteoma, both conservative and operative, have been proposed.&#x0D; CLINICAL CASE: A 17-year-old patient underwent surgical treatment for trapezium bone neoplasm and pronounced chronic pain syndrome.&#x0D; DISCUSSION: The identification and treatment of osteoid osteoma remain challenging, which is associated with the similarity of clinical symptoms and ineffectiveness (in the initial stages of its development) of X-ray examination. Thus, computed tomography is necessary to identify a pathological structure. If a formation on the hand is detected, surgery (tumor resection) is advised; if necessary, bone grafting of the defect is performed. After surgical treatment, relapse may occur within 7 months, which is associated with incomplete tumor removal. To confirm the diagnosis, a pathomorphological study is necessary.&#x0D; CONCLUSIONS: Chronic pain syndrome requires a thorough examination of the patient and a differential diagnosis. Surgical treatment allows the restoration of hand functions and alleviates the tumor-associated pain syndrome.

The effect of mirror therapy in the rehabilitation of flexor tendon injuries after primary surgical repair

ObjectiveThe aim of this study was to evaluate the effectiveness of mirror therapy and to provide a clinical basis for better functional recovery in the rehabilitation of patients with flexor tendon injury. Materials and methodsThirty patients were included and randomly divided between two groups: mirror therapy and conventional treatment. A physical therapy program consisting of whirlpool, ultrasound and transcutaneous electrical nerve stimulation was applied to both groups. In the mirror therapy group, flexor tendon gliding, blocking exercises, joint range of motion and resistance exercises were performed with the healthy hand via a mirror. In the conventional treatment group, the same exercises were performed with the affected hand without mirror. This treatment was continued for 12 sessions over 4 weeks. Joint range of motion, handgrip strength, pain, functionality, dexterity and kinesiophobia were evaluated before and after treatment. ResultsMore improvement was observed in the mirror therapy group in terms of pain on visual analog scale, Patient-Rated Wrist Evaluation, Hand Function Index and Disabilities of the Arm, Shoulder and Hand scores (p = 0.025, p = 0.004, p < 0.001 and p < 0.001, respectively). There was no significant difference between groups for the other parameters (Tampa Kinesiophobia Scale, Purdue Pegboard test, total active range movement, or handgrip strength: p > 0.05). ConclusionThis study shows that mirror therapy in postoperative rehabilitation of flexor tendon injuries is more effective than conventional in terms of reducing the severity of pain and restoring hand function.

An implantable, wireless, battery-free system for tactile pressure sensing

The sense of touch is critical to dexterous use of the hands and thus an essential component of efforts to restore hand function after amputation or paralysis. Prosthetic systems have addressed this goal with wearable tactile sensors. However, such wearable sensors are suboptimal for neuroprosthetic systems designed to reanimate a patient’s own paralyzed hand. Here, we developed an implantable tactile sensing system intended for subdermal placement. The system is composed of a microfabricated capacitive pressure sensor, a custom integrated circuit supporting wireless powering and data transmission, and a laser-fused hermetic silica package. The miniature device was validated through simulations, benchtop assessment, and testing in a primate hand. The sensor implanted in the fingertip accurately measured applied skin forces with a resolution of 4.3 mN. The output from this novel sensor could be encoded in the brain with microstimulation to provide tactile feedback. More broadly, the materials, system design, and fabrication approach establish new foundational capabilities for various applications of implantable sensing systems.

Restoring Function of the Flexor Tendons of the Hand: State of the Science in Kazakhstan.

We conducted a literature review to highlight the diagnosis and treatment of hand flexor tendon injuries and discuss the current state of the science of hand surgery in the Republic of Kazakhstan. We reviewed the Google Scholar, PubMed, Web of Science, Elsevier, and National Center for Biotechnology Information databases and other printed sources for open access articles in three languages. We accepted relevant scientific articles that reflected the peculiarities of restoring function of the tendon flexors of the hand. We reviewed articles from the present to the previous 20 years and included 31 of these sources in our literature review. The medical examination of a patient who has sustained a flexor tendon injury should be thorough and gradual, supported by ultrasound and X-ray examination. For effective restoration of hand function following a hand injury, it is important for the surgeon to conduct a step-by-step assessment of the damage that has occurred to soft tissues, superficial and deep tendons, bones, nerves, and blood vessels. The main goal of tendon repair is to preserve tendon function. It is also known that early postoperative tendon movement leads to faster healing. The most frequent complications associated with flexor tendon repair include the development of adhesions, wound infection, tendon rupture, impaired hand function, and scar formation. Relative to the state of the science in the Republic of Kazakhstan, we conclude that hand surgery should be performed by highly skilled specialists in the field of microsurgery in a specialized department with microsurgical equipment.

Prespinal Versus Conventional Hemicontralateral C7 Nerve Transfer in the Treatment of Total Brachial Plexus Roots Avulsion Injuries: A Retrospective Study With a Minimum Follow-Up Period of 4 Years

Contralateral C7 (CC7)-to-median nerve transfer has been commonly used to restore hand function in brachial plexus injury. To shorten the nerve graft, the prespinal route was described and achieved direct coaptation when combined with humeral shortening osteotomy. The limb was positioned at 0° shoulder abduction and neutral head position. Given our concern about donor-site morbidity when harvesting the whole CC7 nerve and tension across the neurorrhaphy site after mobilization, we aimed to describe our modified prespinal route and compare its outcomes and complications with the conventional hemi-CC7 transfer. From 2004 to 2014, 39 patients with preganglionic total brachial plexus root avulsion injuries, with a minimum of 4 years of follow-up, were included. Overall, 20 and 19 patients underwent the conventional hemi-CC7-to-median nerve and hemi-CC7-to-lower trunk (LT) transfer through the modified prespinal route, respectively. The modified prespinal route was combined with bilateral clavicle shortening osteotomy to achieve direct coaptation to the LT at 45° shoulder abduction. The modified prespinal route showed the median period to achieve ≥M3 hand grip assessed in clinical follow-up was shorter (26.5 months vs 45.5 months), and a higher proportion of patients achieved ≥M3 hand grip recovery (63% vs 30%). One patient experienced symptomatic phrenic nerve injury; however, the hemidiaphragm fully recovered after 6 months. The long-term donor-site complication rate was 2.6%, including one sensory abnormality, and no permanent donor-site weakness after hemi-CC7 harvesting was observed. The modified prespinal route combined with clavicle osteotomy allowed direct coaptation to the LT and did not require head immobilization. It may allow a higher proportion of patients to achieve ≥M3 hand grip more quickly than conventional hemi-CC7 transfer. Therapeutic IV.

Plastic-Reconstructive Hand Surgery: a Multidisciplinary Procedure

The present study aims to provide a detailed and accurate summary of reconstructive aesthetic hand surgery in medical terms. This specialized surgical intervention comprehensively addresses the functional and aesthetic alterations affecting the hand, through complex and personalized techniques.Aesthetic reconstructive hand surgery is indicated in a variety of clinical situations, including hand trauma, congenital malformations, degenerative diseases, soft tissue defects, tumors and post-surgical reconstruction. Each case requires a thorough and personalized evaluation to determine the most appropriate surgical approach and to achieve satisfactory results.The anatomical complexity of the hand, consisting of bones, joints, tendons, muscles, nerves and blood vessels, requires in-depth knowledge on the part of the surgeon. The multidisciplinary approach, in collaboration with specialists in plastic surgery, orthopedic surgery, occupational therapy, physiotherapy and rehabilitative medicine, is crucial to the success of the intervention.Aesthetic reconstructive hand surgery seeks to restore hand function, improve aesthetic appearance and ultimately improve patients' quality of life. The focus is on repair and reconstruction of affected tissues, correction of deformities, stabilization of joints, revision of scars, and optimization of hand shape and contour

Functional Aspects of Hand Reconstructive Surgery

Hand reconstructive surgery has become an increasingly important specialty due to the increasing incidence of hand injuries in the general population. According to the World Health Organization, hand injuries are responsible for about 10% of all emergency department visits. The hand is a complex structure consisting of many bones, muscles, tendons, nerves, and blood vessels. Hand function is essential for performing everyday activities, such as eating, dressing, working, and participating in recreational activities. Hand injuries can have a significant impact on a patient's quality of life and can limit their ability to perform daily activities and work. Hand reconstructive surgery aims to restore hand function and improve the patient's quality of life. The choice of surgical technique should be based on the cause and severity of the injury, as well as the preferences of the patient and surgeon.
