Stabilization of the hypoplastic thumb type Blauth IIIB using a non-vascularized proximal interphalangeal joint from the toe as an alternative reconstruction when pollicization is not accepted: Description of the surgical technique.

BACKGROUND: A Blauth IIIB hypoplastic thumb is a significant functional and cosmetic problem for the developing hand in children. The gold standard in treatment is amputation and index pollicization. Despite the good functional results, some parents do not consent to the operation, mainly for cosmetic reasons. OBJECTIVES: The aim is to present a detailed description and features of the technique used in our department for stabilization of a hypoplastic thumb type Blauth IIIB with a non-vascularized proximal interphalangeal joint from the toe. This is the first description of this surgery for this kind of congenital defect, together with the largest group of patients analyzed compared to alternative techniques described in the literature. MATERIAL AND METHODS: Sixteen patients were included in the analysis. The mean age was 3 years (standard deviation (SD) ±2). In most cases, it was a unilateral and isolated defect. We described the surgical technique and postoperative management in detail and assessed intraoperative factors such as donor selection, operative time, technical problems, stabilization time, complication rate, and reoperations. Appropriate statistics were performed. RESULTS: Most often, the graft was taken from the 3rd toe. The average operation time was 59 ±17.5 min. No technical problems were found during the surgery. The Kirschner wire was removed after an average of 6.5 weeks. The complication rate was 25%, which included the destabilization of Kirschner wires or graft non-union, but it decreased to 6% after reoperation. Five patients underwent tendon transfers. CONCLUSIONS: The presented technique is based on principles such as vascularized metatarsophalangeal joint transplants. It may be an option for stabilizing a hypoplastic thumb if parents do not consent to pollicization. Having microsurgical skills is unnecessary. The operation and anesthesia times are significantly shorter, resulting in less burden on the child's body. The study will continue assessing long-term postoperative functions and the comparison to pollicization.

Biomechanical evaluation of the wrist after scaphotrapeziotrapezoid arthrodesis.

BACKGROUND: The main objective of the present study was to present the biomechanical properties of the wrist in patients who underwent scaphotrapeziotrapezoid arthrodesis when compared to a healthy control hand. METHODS: The study group consisted of 29 consecutive patients who underwent a scaphotrapeziotrapezoid wrist arthrodesis at least 1 year before the research onset. Both hands of all patients were examined in 4 main categories. RESULTS: Average score obtained in the VAS, before the surgery, without motion of the wrist was 5.21 (SD = 3.04), whereas with wrist motion, it was 8.10 (SD = 1.37). Nineteen (65.52%) patients exhibited weakened wrist muscle strength. After the surgery, only 5 (17.24%) patients declared pain in the wrist. Furthermore, the results obtained in the VAS statistically significant differed from the ones before (p < 0.05). Twenty-eight (96.55%) patients were able to resume their profession. Twenty-seven (93.10%) patients stated that they would opt for the operation again. The peak torque during the analysis of extension of the wrist in the isometric protocol was found to be 8.1 Nm (SD = 2.9), 7.9 Nm (SD = 2.3), and 7.9 Nm (SD = 2.5) in the operated hands and 10.9 Nm (SD = 3.2), 9.6 Nm (SD = 2.9), and 9.1 Nm (SD = 3.8) in non-operated hand for 30° extension, no-flexion, and 30° flexion positions, respectively (p < 0.05). CONCLUSION: The current study is the first to present the biomechanical parameters of flexor and extensor muscles of the wrist and fingers in patients after the said procedure. Biomechanical assessments with additional isometric, isotonic, and isokinetic tests provide an opportunity to objectify treatment outcomes and guide appropriate rehabilitation by monitoring its effects.

Hand and wrist - what the hand surgeon wants to know from the radiologist.

Hand surgeons, as unique specialists, appreciate the complexity of the anatomy of the hand. A hand is not merely a group of anatomic structures but a separate organ that works by feeling, sending information to the brain, and enabling a variety of movements, from precise skills to firm tasks. Acute and chronic problems interfere with complicated hand function and potentially influence work or daily life activities for a long time. Thus, the surgeon's role is to propose appropriate treatment with predictable results. This paper attempts to specify the preoperative considerations and their influence on the choice of surgical procedure and the assessment of results potentially influencing further treatment. We have divided the manuscript by anatomical structures, which is a natural surgical assessment and planning approach. The most common problems were highlighted to introduce the method of decision-making and surgical solutions.

Assessing complications and functional outcomes in proximal humerus fracture management: a retrospective comparison between conservative and intramedullary nailing treatments.

INTRODUCTION: Fractures of the proximal end of the humerus (FPH) are the second most common fractures in the upper limb after fractures of the distal radius and are two to three times as common in women than in men. Therefore, the main objective of the present study was to compare and analyze the complications and the functional outcomes in patients with displaced FPH receiving conservative and surgical treatments with intramedullary nailing. METHODS: A retrospective cross-sectional study was conducted to establish the differences in complications risks between surgical and non-surgical treatment of the FPH. For this purpose, the clinical and radiological results of 67 consecutive patients were analyzed. RESULTS: A total of 25 patients were included in the non-surgically treated group. A total of 42 patients were included in the surgically treated group. Complications occurred in a total of 4 (16.0%) patients after the non-surgical treatment. Those included frozen shoulder (n = 2), nonunion (n = 1), and avascular necrosis of the humeral head (n = 1). Complications occurred in a total of 18 (42.6%) patients after the surgical treatment. Non-surgically treated patients had statistically significantly (p < 0.05) lower scores in the Constant-Murley scale in all of the categories. CONCLUSION: The present study demonstrates an overall prevalence of complications to be 16% in patients treated conservatively and 42.6% in patients treated surgically. In the non-surgical cohort, the frozen shoulder was the most frequently observed complication (8%). Interestingly, non-anatomical repositioning was the most prevalent complication in surgically treated patients. Due to the complexity of the FPH, we believe that the surgeon needs to have comprehensive knowledge regarding the characteristics of this fracture, the available treatment options, and the possible complications that may occur. This can enhance patient safety and provide satisfactory clinical outcomes.

Handball players have superior shoulder proprioception: a prospective controlled study.

BACKGROUND: Proper proprioceptive and neuromuscular control is crucial for the overhead athlete's performance. The aim of the present study was to evaluate the shoulder joint position sense (JPS) levels in overhead throwing athletes. The secondary aim was to confront the proprioceptive abilities with glenohumeral adaptive changes and pathologies among athletes. METHODS: Ninety professional handball players and 32 healthy volunteers were recruited. JPS levels were measured by an electronic goniometer and expressed as values of an active reproduction of the joint position (ARJP) and as error of ARJP (EARJP) in 3 different reference positions for each movement (abduction and flexion at 60°, 90°, and 120°; internal [IR] and external rotation [ER] at 30°, 45°, and 60°). RESULTS: Side-to-side differences revealed significantly better values of EARJP for the throwing shoulders in abduction at 90° and 120°, flexion at 90° and 120°, IR at 60°, and ER at 30° and 60° compared with the nonthrowing shoulders. Handball players showed significantly better proprioceptive levels in their throwing shoulder compared to the dominant shoulder of the control group in abduction at 90° (P = .037) and 120° (P = .001), flexion at 120° (P = .035), IR at 60° (P = .045), and in ER at 60° (P = .012). DISCUSSION: Handball players present superior shoulder JPS in their dominant throwing shoulder at high range of motion angles when compared to a nonathlete population and to their own nondominant shoulder.

Isometric Shoulder Testing Using a Forcemeter Is a Reliable Method of Strength Evaluation.

Isometric strength testing using a digital dynamometer is reliable for muscle function evaluation. It allows us to objectify manual strength assessment measurement. We tested intra- and inter-observer reliability of a user-friendly efficient digital dynamometer-the Forcemeter-equipped with a computer program to monitor the measurements and to store the data. Abduction, forward flexion, and external and internal rotation of both shoulders were tested three times in 20 healthy volunteers with no record of shoulder trauma. Isometric contracture was recorded in newtons. The first and the third test were carried out by Examiner A (intra-rater reliability); the second test, by Examiner B (inter-rater reliability). Good reliability was shown for intra-class correlation coefficient (ICC) values which mean moderate to high correlations (r = 0.66-0.93) for both examiners. Moderate to high correlations (r = 0.72-0.91) were found for comparisons between the results obtained by Examiner A.

Delayed Surgical Treatment in Patients with Chronic Carpal Tunnel Syndrome Is Still Effective in the Improvement of Hand Function.

Background and Objectives: Severe carpal tunnel syndrome (CTS) is the most common compression neuropathy in the upper extremities treated conservatively; later, when advanced, CTS is treated mostly surgically. The most prevalent symptoms comprise numbness, as well as sensation loss in the thumb, index, and middle finger, and thenar muscle strength loss, resulting in impaired daily functioning for patients. Data on the results of CTS treatment in patients with delayed surgical intervention are scarce. The aim of this study was to determine the postoperative results of chronic carpal tunnel syndrome treatment in patients with symptoms lasting for at least 5 years. Materials and Methods: A total of 86 patients (69 females, 17 males) with a mean age of 58 years reporting symptoms of CTS for at least 5 years (mean: 8.5 years) were prospectively studied. The average follow-up time was 33 months. All patients underwent the surgical open decompression of the median nerve at the wrist. A preoperative observation was composed of an interview and a clinical examination. The subjects completed the DASH (the Disabilities of the Arm, Shoulder, and Hand), PRWE (Patient-Rated Wrist Evaluation), and self-report questionnaires. Global grip strength, sensory discrimination, characteristic symptoms of CTS, and thenar muscle atrophy were examined. Postoperatively, clinical and functional examinations were repeated, and patients expressed their opinions by completing a BCTQ (Boston Carpal Tunnel Syndrome Questionnaire). Results: We found improvements in daily activities and hand function postoperatively. Overall, 88% of patients were satisfied with the outcome of surgery. DASH scores decreased after surgery from 44.82 to 14.12 at p < 0.001. PRWE questionnaire scores decreased from 53.34 to 15.19 at p < 0.001. The mean score of the BCTQ on the scale regarding the severity of symptoms was 1.48 and 1.62 on the scale regarding function after surgery. No significant differences were found in the scores between the male and female groups or between age groups (p > 0.05). A significant increase in global grip strength from 16.61 kg to 21.91 kg was observed postoperatively at p < 0.001. No significant difference was detected in the measurement of sensory discrimination (6.02 vs. 5.44). In most of the examined patients, night numbness and wrist pain subsided after surgery at p < 0.001. Thenar muscle atrophy diminished after surgery at p < 0.001. Conclusions: Most patients were satisfied with the results of CTS surgery regarding the open decompression of the median nerve even after 5 years of ineffective conservative treatment. Significant improvement of the hand function was confirmed in the functional studies.

End-to-Side vs. Free Graft Nerve Reconstruction-Experimental Study on Rats.

The long history of regeneration nerve research indicates many clinical problems with surgical reconstruction to be resolved. One of the promising surgical techniques in specific clinical conditions is end-to-side neurorrhaphy (ETS), described and then repeated with different efficiency in the 1990s of the twentieth century. There are no reliable data on the quality of recipient nerve regeneration, possible donor nerve damage, and epineural window technique necessary to be performed. This research attempts to evaluate the possible regeneration after end-to-side neurorrhaphy, its quality, potential donor nerve damage, and the influence of epineural windows on regeneration efficiency. Forty-five female Wistar rats were divided into three equal groups, and various surgical technics were applied: A-ETS without epineural window, B-ETS with epineural window, and C-free graft reconstruction. The right peroneal nerve was operated on, and the tibial nerve was selected as a donor. After 24 weeks, the regeneration was evaluated by (1) footprint analysis every two weeks with PFI (peroneal nerve function index), TFI (tibial nerve function index), and SFI (sciatic nerve function index) calculations; (2) the amplitude and latency measurements of motor evoked potentials parameters recorded on both sides of the peroneal and tibial nerves when electroneurography with direct sciatic nerve electrical stimulation and indirect magnetic stimulation were applied; (3) histomorphometry with digital conversion of a transverse semithin nerve section, with axon count, fibers diameter, and calculation of axon area with a semiautomated method were performed. There was no statistically significant difference between the groups investigated in all the parameters. The functional indexes stabilized after eight weeks (PFI) and six weeks (TFI and SFI) and were positively time related. The lower amplitude of tibial nerve potential in groups A and B was proven compared to the non-operated side. Neurophysiological parameters of the peroneal nerve did not differ significantly. Histomorphometry revealed significantly lower diameter and area of axons in operated peroneal nerves compared to non-operated nerves. The axon count was at a normal level in every group. Tibial nerve parameters did not differ from non-operated values. Regeneration of the peroneal nerve after ETS was ascertained to be at the same level as in the case of free graft reconstruction. Peroneal nerves after ETS and free graft reconstruction were ascertained to have a lower diameter and area than non-operated ones. The technique of an epineural window does not influence the regeneration result of the peroneal nerve. The tibial nerve motor evoked potentials were characterized by lower amplitudes in ETS groups, which could indicate axonal impairment.

The Usefulness of Motor Potentials Evoked Transvertebrally at Lumbar Levels for the Evaluation of Peroneal Nerve Regeneration after Experimental Repair in Rats.

Motor evoked potentials (MEPs) are used in neurology as part of a precise diagnostic method to study the transmission of efferent neural impulses at the central and peripheral levels of the nervous system. Previous attempts have been made to apply MEPs in animal studies for evaluating neural transmission at the motor cortex center level to the muscles of the forelimbs and hindlimbs. In clinical and experimental studies, little attention is focused on the significance of the magnetic stimulation of spinal cord structures with the direct recording of the evoked potentials from peripheral nerve motor fibers. The aim of this paper was to evaluate the usefulness of the motor potentials evoked transvertebrally at lumbar levels in the evaluation of experimental peroneal nerve regeneration in rats. The bilateral transmission of efferent impulses in the distal parts of the peroneal and tibial nerves was verified by recordings of evoked potentials following transvertebral magnetic stimulation at lumbar levels (MEPs) and the electrical stimulation of the sciatic nerve in classical electroneurographic (ENG) tests for comparison. Recordings were performed 24 weeks after grafts on surgically treated hindlimbs as well as on non-operated hindlimbs as controls. Both the MEP and ENG stimulations resulted in evoked potentials with larger amplitude values following the application of the magnetic pulses, with more being recorded on the non-operated hindlimbs than on the operated ones when recordings were taken from peroneal nerve branches. We observed statistically significant correlations between the MEP and ENG results for peroneal and tibial nerve amplitude on the non-operated side and peroneal nerve amplitude on the operated side. The recorded latencies of the evoked potentials were shorter in the ENG studies than in the MEPs for the non-operated side. The results demonstrated the phenomenon of regeneration in the motor fibers of the peroneal nerves 24 weeks after grafting in the experimental conditions. In this study, the MEPs were as useful as the ENG studies for evaluating regeneration in the motor fibers of hindlimb nerves in rats, although they were not significantly different. This paper discusses the clinical importance of transvertebral MEPs induced at the lumbosacral and cervical levels with a magnetic field for the diagnostic evaluation of efferent impulse transmission at different levels of the motor pathway.

Evaluation of the ulna lengthening by distraction osteogenesis in congenital radial deficiency.

PURPOSE: Publications evaluating the results of the ulna lengthening in congenital radial deficiency are based only on small groups of subjects which yield statistical studies of low scientific value. The aim was to examine the effectiveness of ulna lengthening in radial longitudinal deficiency and determine the number and quality of complications based on one of the most numerous study groups described in the literature. METHODS: The material consists of a study group with 31 upper limbs of unmatured patients diagnosed with type III and IV radial longitudinal deficiency. The study group was evaluated based on the parameters known from the literature. The difficulties during elongation were classified according to Paley's classification. RESULTS: The study group contained patients with a mean age of 9 years, and the number of boys and girls was comparable. Ulna length significantly increased after elongation compared to the initial bone length. The patient's age didn't affect the ulna lengthening, and the amount of elongation didn't significantly affect the total stabilization period. However, the total stabilization time increased with increasing patient age. Difficulties affected more than half of the cases. CONCLUSIONS: Ulna elongation in congenital radial deficiency results in significant lengthening of the ulna, and thus the entire forearm, compared to the initial bone length. This technique has a high percentage of difficulty, so its use should be considered after cautious discussion with the parents and patients.

Isokinetic and functional shoulder outcomes after arthroscopic capsulolabral stabilization.

INTRODUCTION: Shoulder stability is secured by dynamic and static stabilizers. Rotator cuff is responsible for dynamic stabilization. In cases of shoulder instability their activity is disturbed. Capsulolabral repair restores mainly static stabilization. This surgery treatment technique of shoulder instability was first described by Bankart in 1923. His idea, with further modifications, is commonly used up to this day. Evaluation of muscle shoulder recovery after stabilization should be one of the important criteria to allow patient to return to sport and work. However, not much isokinetic assessment after capsulolabral repair was described. The aim of this study were the following: the comparative assessment of the shoulder rotatory strength in patients following arthroscopic capsulolabral repair of unilateral anterior traumatic instability and clinical assessment with comparison of pre and post-operative results. MATERIAL AND METHODS: Forty-five patients, 14 women and 31 men, with an average follow-up of 4.4 years were tested bilaterally for internal and external rotation strength at four angular velocities. ASES and UCLA tests were collected before and after surgery. RESULTS: The values of peak moment and muscle power parameters were slightly lower for an operated shoulder in comparison to a healthy shoulder for the external rotation. Total work parameter in external rotation was significantly lower for the operated shoulder in comparison to the non-operated side. The internal/external muscle group balance was lower for the operated shoulder in comparison to reference values in the women group. Furthermore, both ASES and UCLA scores were significantly higher after operation. CONCLUSIONS: After arthroscopic capsulolabral shoulder stabilization, slight differences in isokinetic evaluation, especially in external shoulder rotation, occur. It affects rotators muscle balance. In functional evaluation significant improvement in shoulder function occurs.

Three-year (2017-2019) activity report of the Replantation Service for hand amputations in Poland.

This article summarises activity of the Replantation Service for hand amputations in Poland in years 2017-2019. Over this period a total of 551 cases of total and subtotal amputations as well as other complex injuries to the hand were referred to the referenced centres. Of these, 330 referrals were accepted and 221 rejected, for various reasons. Among these accepted, there were 165 total (50%) and 131 subtotal (40%) amputations; 34 patients (10%) had other severe hand injuries. Vast majority of the patients constituted young and middle-age males. The most common was amputation of several digits and thumbs - a total of 251 cases (76%), followed by transmetacarpal - 30 (9%), forearm - 23 (7%) and wrist - 20 (6%) amputations. Replantation of amputated extremity was performed in 138 patients (42%), revascularization in 98 (30%) and in 45 (14%) primary repair of the complex injuries. In 26 cases (8%), coverage of tissue defects was performed, and in 23 (7%) primary terminalization. Survival rate was of a mean of 65% for replantations and 85% for revascularizations. Comparing to the previously reported period 2013-2017, the number of treated patients was similar, but structure of injuries differed: number of digital amputations increased (of 22 cases), whereas number of proximal amputations (hand, forearm and arm) significantly dropped (of 50 cases). The importance of Replantation Service, an informal structure, in saving limbs of severely mutilated patients was emphasised.

Clinical and radiological examination of bony-mediated shoulder instability.

The coexistence of glenoid and humeral head bone defects may increase the risk of recurrence of instability after soft tissue repair.Revealed factors in medical history such as male gender, younger age of dislocation, an increasing number of dislocations, contact sports, and manual work or epilepsy may increase the recurrence rate of instability.In physical examination, positive bony apprehension test, catching and crepitations in shoulder movement may suggest osseous deficiency.Anteroposterior and axial views allow for the detection of particular bony lesions in patients with recurrent anterior shoulder instability.Computed Tomography (CT) with multiplanar reconstruction (MPR) and various types of 3D rendering in 2D (quasi-3D-CT) and 3D (true-3D-CT) space allows not only detection of glenoid and humeral bone defects but most of all their quantification and relations (engaging/not-engaging and on-track/off-track) in the context of bipolar lesion.Magnetic resonance imaging (MRI) is increasingly developing and can provide an equally accurate measurement tool for bone assessment, avoiding radiation exposure for the patient.

Synovial plica of the elbow and its clinical relevance.

A synovial plica (fold) is normal anatomic finding, and occurs in 86-100% of cases; however, symptomatic plica is much less common (7.2-8.7% of all elbow arthroscopies).Synovial plica syndrome is a painful elbow condition related to symptomatic synovial plica.Synovial plica syndrome is diagnosed by clinical examination (lateral elbow pain) commonly accompanied by local tenderness, pain at terminal extension and/or painful snapping.Synovial plica syndrome may be mimicked by other elbow conditions, commonly tennis elbow, loose bodies, and degenerative arthritis.Magnetic resonance imaging or ultrasound scan may support diagnosis in correlation with clinical findings, but symptomatic plica may also be diagnosed as unexpected during elbow arthroscopy.The arthroscopic resection is effective and safe if conservative treatment fails.

Beneficial Effects of Pulsed Electromagnetic Field during Cast Immobilization in Patients with Distal Radius Fracture.

To assess whether pulsed electromagnetic field therapy during cast immobilization of distal radius fractures has beneficial effects on pain and limb function, the study included 52 patients (mean age 60.8 ± 15.0 years) with distal radius fractures treated with cast immobilization. Patients were allocated to a pulsed electromagnetic field group (n = 27) or a control group (n = 25). Pain; forearm and arm circumference; range of motion; disabilities of the arm, shoulder, and hand score; and touch sensation were evaluated on the day of the plaster cast dressing and 3 and 6 weeks after. In comparison to the control group, the pulsed electromagnetic field group reported significant changes after 3 and 6 weeks of treatment: lower pain levels (p=0.0052; p < 0.0001, respectively), greater mobility of upper-limb joints, improvement in exteroceptive sensation, and reduction in disability of the upper limb (disabilities of the arm, shoulder, and hand) (p=0.0003; p < 0.0001, respectively). Our results suggest that early addition of pulsed electromagnetic field treatment, during cast immobilization of distal radius fractures, has beneficial effects on the pain, exteroceptive sensation, range of motion, and daily functioning of patients.

Factors affecting the final outcomes after reconstruction of the median and ulnar nerve at the level of the forearm: Analysis of 41 patients.

BACKGROUND: Upper extremity injuries have a significant impact on social and professional life. They represent about 10% of visits to emergency departments. Nerve lacerations are one of the biggest problem because loss of innervation results in muscle atrophy, decreased sensibility, and therefore permanent dysfunction. Appropriate treatment is very important for patients to regain function. MATERIALS AND METHODS: The study included 41 patients, 30 men and 11 women who underwent nerve repair surgery in the middle and distal forearm level in the years 2001-2017. The patients' age ranged from 9 to 73 years with an average of 37 years. They were divided into 3 groups with repaired median, ulnar and both nerves. We determined time from injury to nerve repair, assessed sensitivity in index and little finger with a two-point discriminator, and muscle strength by measuring adduction of the little finger and palmar abduction of the thumb.Results were rated based on Medical Research Council Scale (MRC). In addition, general hand disability was assessed according to the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH). RESULTS: There was a statistically significant (p = 0.0197), positive correlation (r > 0) between the period from injury to surgery and the DASH score, and statistically significant difference (p = 0.0001) in return of muscular function between groups with median, ulnar and both nerves injury. Also correlation between patients age and score of DASH was statistically significant (p = 0.0140) with positive correlation (r > 0). There was no statistically significant difference in the return of sensitivity (p = 0.4337) and the DASH score (p = 0.3831) between these three groups. CONCLUSIONS: Patients with shorter time from injury to repair and at a younger age had better DASH results. The median nerve had the best motor function between the groups. There was no difference in sensitivity or DASH scores between groups.

The Effects of Nerve and Tendon Gliding Exercises Combined with Low-level Laser or Ultrasound Therapy in Carpal Tunnel Syndrome.

BACKGROUND: Carpal tunnel syndrome (CTS) is a common medical condition that doctors and physiotherapists come across in clinical practice. There are no explicit recommendations concerning which physical therapy methods should be applied in its treatment; however, there have also been no studies on the effects of combining low-level laser therapy (LLLT) or ultrasound with nerve and tendon gliding exercises. The purpose of this study was to evaluate the therapeutic efficacy of ultrasound and LLLT combined with gliding exercises. MATERIALS AND METHODS: A total of seventy patients with mild to moderate CTS, divided into two groups, were included in this study. Group 1 received ultrasound treatment, whereas Group 2 underwent LLLT. The treatment lasted 2 weeks (5 sessions/week). In addition, both groups were treated with nerve and tendon gliding exercises three times daily. The clinical evaluation involved an interview on subjective and objective sensory abnormalities, the intensity of pain, the measurement of grip strength, Phalen's test, Tinel's sign, and the Boston Carpal Tunnel Questionnaire. The assessment was performed before and after the treatment. RESULTS: A decrease in sensory impairments, improvement in visual analog scale, hand grip strength and the Boston Questionnaire results were significant in all patients after therapy. No meaningful differences between groups were noted in any of the examined variables after treatment. No adverse effects were observed. CONCLUSIONS: The results of this study may suggest the clinical efficacy of LLLT or ultrasound combined with gliding exercises in patients with mild to moderate CTS.

Bilateral shoulder proprioception deficit in unilateral anterior shoulder instability.

HYPOTHESIS AND BACKGROUND: Proprioception is an important element of shoulder dynamic stability. It has been shown to be affected in cases of capsular or labral injuries of the glenohumeral joint. Therefore, this study was conducted to investigate bilateral shoulder proprioception by active reproduction of joint position both in patients with post-traumatic recurrent unilateral shoulder instability and in normal healthy volunteers. METHODS: We compared 41 patients, comprising 11 female and 30 male patients with an average age of 25.6 years (range, 18-39 years), with post-traumatic unilateral anterior shoulder instability with a control group of 27 healthy volunteers with no history of shoulder problems and with normal shoulder function during examination. All patients were examined using a high-accuracy computer-controlled electronic goniometer (Propriometer). The error of active reproduction of joint position (EARJP) was measured in abduction, flexion, external rotation, and internal rotation in both shoulders. RESULTS: We observed a significant deficit in the EARJP in the unstable shoulders within the instability group. Surprisingly, similar results were recorded for the contralateral, unaffected shoulders within this group of patients compared with the control group. Joint acuity increased with higher elevation of the arm position. CONCLUSION: Unilateral shoulder injuries, resulting in instability, affect proprioception in both shoulders, as demonstrated by an increased EARJP. This is the first report of unilateral shoulder instability coexisting with inferior proprioception in both shoulders.

Three-year (2014-2016) activity report of the Replantation Service for hand amputations in Poland.

The paper summarizes 32 months (January 2014 - August 2016) of activity of the Replantation Service for hand amputation in Poland. Over this period a total of 568 cases of total and subtotal amputations as well as other complex injuries to the hand were referred. Of these, 354 referrals (62%) were accepted and 214 (38%) rejected. Among accepted, there were 167 total (47%) and 142 subtotal (40%) amputations; 45 patients (13%) had other severe hand injuries. Vast majority of the patients constituted males aged a mean of 39 years. The most common injury was amputation of several digits in one patient, and thumb amputation - a total of 229 cases (65%), followed by transmetacarpal and wrist amputations - 92 (30%) and forearm/arm amputations - 33 cases (9%). Replantation of amputated extremity was performed in 141 patients (40%), revascularization in 145 (41%) and in 29 (8%) primary repair of the complex injuries. In 27 cases (8%), a coverage of the tissue defects, and in 12 (3%) primary terminalization was performed. Survival rate was of 78% for replantation and revascularization. Comparing to the period 2010-2012, an increase in number of treated patients (of n=64 cases), in number of amputations (of 96 cases) and in number of amputated digits (of 88 cases) were noted. The activity report shows importance of Replantation Service, an informal structure, in saving limbs of severely mutilated patients.
