Case-based report of graded motor imagery experience in traumatic brachial plexus injury: The art of moving without moving.

BACKGROUND: We reported a 24-year-old woman who sustained multiple upper limb injuries after a traffic accident in March 2017. She sustained a C7-T1 brachial plexus injury and radial nerve injury on the left side diagnosed in November 2017. The patient underwent radial nerve reconstruction. The patient began her comprehensive therapy program in January 2018. PURPOSE: To describe the use of graded motor imagery (GMI) and outcomes after traumatic brachial plexus palsy. We presented changes in electromyographic (EMG) activity of target muscles during task execution and functional status following 10-session GMI therapy. STUDY DESIGN: Case report. METHODS: The program included 4 sessions of motor imagery and 6 sessions of a combination of motor imagery and mirror therapy. RESULTS: The patient successfully participated in the program with reported improvements in EMG activity, functional status, emotional well-being, and body awareness. CONCLUSIONS: GMI therapy appears to have peripheral motor effects, including altered surface EMG activity and contributes to a favorable outcome in the functional level of the affected arm. An improved emotional state and awareness of the affected hand could have a positive effect on function. Future long-term randomized controlled trials are needed to investigate the cumulative peripheral effects of treatment of graded motor imagery and the effects of variables mediating its effects on functional performance in patients with nerve injury.

Facet Inclinations and Interfacet Angle of the Distal Radius on Posteroanterior Radiographs: Clinical Associations With 3 Carpal Pathologies.

PURPOSE: The radiographic interfacet angle (IFA), scaphoid facet inclination (SFI), and lunate facet inclination (LFI) of the distal radius were measured in patients with 3 distinct wrist pathologies to determine whether there is an association between these radiographic measurements and these conditions. METHODS: Posteroanterior wrist radiographs were compiled from patients with 3 types of common wrist pathologies (scaphoid waist fracture [n = 54], scapholunate [SL] dissociation [n = 23], and dorsal ganglion [n = 51]). The patients were all Caucasians aged 20 to 45 years who met strict radiographic criteria. The IFA, SFI, and LFI values of these patients were compared with those obtained from 400 normal wrist radiographs of subjects who met the same selection criteria. RESULTS: In men with a scaphoid waist fracture, the IFA and SFI were significantly greater than in normal men, whereas the LFI was significantly lower. In the SL dissociation group, for all patients and for subgroups stratified according to sex, the IFA and SFI were significantly lower than in the normal matched groups. In the dorsal ganglion group, differences were found in the IFA and SFI for women, but not for men. CONCLUSIONS: The facet orientations of the distal radius in patients with scaphoid fracture, SL dissociation, and dorsal ganglion differed from those in the normal population. The IFA alone is most likely to be associated with all 3 pathologies. The SFI and LFI are less likely to be associated with patients with carpal pathologies. CLINICAL RELEVANCE: Patients with a greater IFA may be susceptible to scaphoid fractures when they fall on an overstretched hand. Patients with a smaller IFA may be susceptible to SL dissociation when they fall on an overstretched hand.

Replantation of forequarter amputation: Report of two cases with successful structural, motor and sensorial results.

Although there have been numerous reports of major replantation of upper extremity amputations, limited numbers of above-elbow amputation replantation have been reported. We present the technical details of two successful replantations of forequarter amputations in a nine-year-old girl and a three-year-old boy. In both cases, the forequarter was amputated due to avulsion traction injuries resulting in amputation including the entire upper limb, while the integrity of the scapula and parascapular muscles was maintained, with no injury to the glenohumeral joint. Replantation was performed, involving a shorter ischemia time with proper fixation, and vascular and neural repairs. Postoperative recovery was uneventful, and motor and sensorial acquisition were quite satisfactory during follow-up periods of 9 and 6 years, respectively. Proper fixation of the amputated part mimicking the original anatomy, radical debridement of avulsed vessels, and reconstruction of the defect using long vein grafts and neural repair while maintaining proper integrity are the most important factors in success. When the requirements are met, replantation of the forequarter in a child yields a superior outcome, from both the functional and esthetic perspectives. To the best of our knowledge, this is the first report in the English literature involving two sequential cases of such high-level replantation resulting in successful reacquisition of both viability and function.

The results of decompression of the musculocutaneous nerve entrapment in children with obstetric brachial plexus palsy.

PURPOSE: Elbow flexion is a key indicator of functional recovery in obstetric brachial plexus palsy (OBPP). However, lack of flexion could be a result of an entrapped musculocutaneous nerve during the healing period. The purpose of this study was to investigate the possible compression of the musculocutaneous nerve and outcomes of decompression. METHODS: The study included 11 children aged with a mean age of 10.9 ± 2.7 months (range, 8-16 months) with Narakas 2 involvement OBPP, who had insufficient elbow flexion but had satisfactory shoulder abduction. Prior to surgery, magnetic resonance imaging (MRI) was performed to identify the entrapment. The children were evaluated pre-operatively and at 3 and 12 months postoperatively using the Active Movement Scale and Faradic Excitability Test. The musculocutaneous nerve was explored and decompressed in all the children. Regular physiotherapy and a home exercise programme were prescribed after surgery. RESULTS: The MRI findings were consistent with the surgical exploration in all the infants. Statistical analyses showed that decompression of the musculoskeletal nerve improved active movement scale scores on elbow flexion and faradic excitability test values of biceps brachii within 3 months after surgery. CONCLUSION: Children with delayed elbow flexion and satisfactory shoulder abduction may have an entrapped musculocutaneous nerve in the proximal arm and decompression of the nerve improves elbow function.

Facet Inclinations and Interfacet Angle of the Distal Radius on Posteroanterior Radiographs.

PURPOSE: To determine the lunate facet inclination (LFI), scaphoid facet inclination (SFI), and interfacet angle (IFA) of the distal radius on posteroanterior (PA) radiographs; evaluate the reliability of the IFA measurements; and define normative reference values for all 3 parameters. METHODS: The IFA was defined as the angle between the lines tangential to the scaphoid and the lunate facets. The reliability of the IFA measurements was investigated using 2 serial measurements made by 3 observers. Three parameters (the IFA, LFI, and SFI) were measured on PA wrist radiographs of 400 normal Caucasians. Between-side and -sex differences among the 3 parameters were analyzed statistically. RESULTS: The inter- and intraobserver reliability of the IFA measurements was excellent. The mean values were as follows: IFA, 20°; LFI, 14°; and SFI, 34°. Although no statistically significant difference was found between the right and the left wrists, sex-based analyses revealed significant differences between the wrists of women and men. Based on the standard distribution of IFAs, 3 groups of distal radii were defined as follows: slightly, moderately, and steeply angled. CONCLUSIONS: The LFI, SFI, and IFA are easily measured radiographic parameters of the distal radius. Although a moderate correlation was evident between the IFA and the LFI, the IFA is a novel parameter to evaluate the carpal articular shape of the distal radius. The IFA measurement on PA radiographs is reliable. CLINICAL RELEVANCE: The LFI has been accepted as a parameter for Madelung deformity and radiocarpal force transmission. The IFA may be considered as a parameter to evaluate radiocarpal coronal stability that could potentially be affected by changes in bifacet curvature.

Elbow flexion reconstruction with nerve transfer or grafting in patients with brachial plexus injuries: A systematic review and comparison study.

INTRODUCTION: Posttraumatic brachial plexus (BP) palsy was used to be treated by reconstruction with nerve grafts. For the last two decades, nerve transfers have gained popularity and believed to be more effective than nerve grafting. The aim of this systematic review was to compare elbow flexion restoration with nerve transfers or nerve grafting after traumatic BP injury. METHODS: PRISMA-IPD structure was used for 52 studies included. Patients were allocated as C5-C6 (n = 285), C5-C6-C7 (n = 150), and total BP injury (n = 245) groups. In each group, two treatment modalities were compared, and effects of age and preoperative interval were analyzed. RESULTS: In C5-C6 injuries, 93.1% of nerve transfer patients achieved elbow flexion force ≥M3, which was significantly better when compared to 69.2% of nerve graft patients (p < 0.001). For improved outcomes of nerve transfer patients, shorter preoperative interval was a significant factor in all injury patterns (p < 0.001 for C5-C6 injuries and total BP injuries, p = 0.018 for C5-C6-C7 injuries), and young age was a significant factor in total BP injury pattern (p = 0.022). CONCLUSIONS: Our analyses showed that nerve transfers appear superior to nerve graftings especially in patients with a C5-C6 injury. Unnecessary delays in surgery must be prevented, and younger patients may have more chance for better recovery. LEVEL OF EVIDENCE: Level II.

Brachial plexus birth injury: advances and controversies.

While there is considerable spontaneous recovery in most cases of brachial plexus birth injury, many children are left with significant problems that may lead to lifelong functional limitations, loss of work and social isolation. Detailed treatment with the right strategy can provide very valuable improvement in function. Over the past few years, the clinical approach to brachial plexus birth palsy has entered a new era in both diagnostic and surgical treatment methods. This article reviews four areas of management, the role of imaging in defining the severity of the injury, the optimal timing of for nerve exploration and reconstruction in appropriate cases, the advantages and potential complications of nerve transfers, and the role of physiotherapy. Available evidence is considered. Although it is difficult to make clear and precise inferences on a subject where there are many variables and considerable uncertainties, some currently accepted views will be summarized.Level of evidence: V.

Health-related quality of life in children with obstetrical brachial plexus palsy.

PURPOSE: We aimed to determine the health-related quality of life (HRQL) of children with obstetrical brachial plexus palsy (OBPP) and examine its association with gender, age, injury level, injured side, and functional status. METHODS: We conducted a controlled, cross-sectional study including 70 children with OBPP. Fifty-two age-matched children without any health problems were included as controls. HRQL was assessed with the short parent form of the Child Health Questionnaire (CHQ-PF28), and functional status was measured using the active movement scale (AMS). RESULTS: Children with OBPP scored significantly lower on most of the CHQ-PF28 subscales than the healthy controls (p < 0.05). Gender or age did not significantly affect scores in any domain (p > 0.05). CHQ-PF28 scores showed that there were significant differences according to the side of injury between groups, especially in the "parental impact-time" and "family activities" domains (p < 0.05). There were no statistically significant differences in CHQ-PF28 scores between groups that had an upper trunk involvement and total injury groups (p > 0.05), except in the "bodily pain/discomfort" domain (p < 0.05). The AMS score was weakly to moderately correlated with the "mental health" and "parental impact-time" and "general health perceptions" domains. CONCLUSION: The study demonstrated that children with OBPP have a poorer HRQL than their healthy peers. Side of injury, limitations in shoulder flexion, shoulder internal rotation, elbow flexion, elbow extension, and forearm supination were important factors affecting the HRQL of the children. The health concepts and factors discussed in the study can guide clinicians aiming to improve QoL of children with OBPP.

Quality of life in mothers of children with obstetrical brachial plexus palsy.

BACKGROUND: The aim of this study was to explore impairment in quality of life (QOL) of the mothers who were primarily responsible for taking care of children with obstetrical brachial plexus palsy (OBPP) and to state its association with the age, sex and functional status of the child with OBPP. METHODS: Ninety-three mothers of children with OBPP and 88 mothers of children without any health problems were included in the study. Children's demographic characteristics were recorded and the functional status of the upper extremity was determined with the active movement scale. The QOL of the mothers was assessed with the Turkish version of the Nottingham Health Profile (NHP). RESULTS: There were significant differences between mothers of children with OBPP and the control group in total, physical activity, energy expenditure, and pain score of the NHP. A decrease in energy expenditure and physical activity levels were found to be related to children's active movement scale results in elbow flexion and extension, and forearm supination. A statistically meaningful difference was found between mothers of children aged 0-2 and mothers of children aged 2-7 years in emotional reaction, social isolation and total score of NHP. CONCLUSIONS: The results of this study revealed that mothers of children with OBPP have poor QOL compared with mothers of healthy children. The limitation in elbow joint movements was found to be important for the mothers. The strongest impact of the illness is on the emotional reactions and social isolation of the mothers. Professionals involved in the care of children with OBPP should also help parents to cope with the burden of caregiving.

The effects of the synovium on chondrocyte growth: an experimental study.

PURPOSE: The objective of this study was to evaluate the effects of synovium on the proliferation of the cartilage tissue and chondrocytes using a rabbit knee model as an in vivo synovial culture medium. METHODS: Twelve New Zealand rabbits were used as the animal model in this investigation. Standard size chondral and osteochondral cartilage grafts were taken from, respectively, the left and right knees of all the animals. Two groups of 6 animals were formed: in Group I (synovium group), grafts were placed into the synovial tissue and in group II (patellar tendon group) behind the patellar tendon of the corresponding knees. After 4 months, samples were collected and evaluated macroscopically by measuring their dimensions (vertical = D1, horizontal = D2, and depth = D3) and volumes, and histologically by counting the chondrocyte number using camera lucida method. RESULTS: Macroscopically, the increase in average D1, D2, and D3 measurements and volume in the osteochondral specimens were significantly higher compared to the chondral specimens in both groups (P < 0.05). However, no significant difference was observed between the two groups in terms of macroscopic values. Histologically, the mean chondrocyte counts in osteochondral and chondral specimens for Group I (synovium) were 20.2 and 18.1, and for Group II (patellar tendon) were 18.7 and 15.6, respectively. The mean number of chondrocytes was found to be significantly higher in osteochondral specimens than that of chondral specimens in either group (P < 0.05). Overall average chondrocyte count was significantly higher for Group I compared to Group II (P < 0.05). CONCLUSION: Transplantation of the cartilage grafts into the synovial tissue in rabbit knees significantly enhanced the chondrocyte production compared with the group where the grafts were transplanted into intra-articular patellar tendon. The results of this study indicate that native synovial tissue may have the potential to be used as an in vivo culture medium for osteochondral tissue growth.

Cross-cultural adaptation, validation, and reliability process of the Michigan Hand Outcomes Questionnaire in a Turkish population.

PURPOSE: The Michigan Hand Outcomes Questionnaire (MHQ) is a domain-specific questionnaire that was developed to be used as a standardized instrument capable of measuring outcomes for patients with all types of hand disorders. The purpose of this study was to develop the Turkish version of the MHQ and to examine whether it is a valid and reliable tool for assessing the outcomes in hand disorders. METHODS: Translation and back-translation of the MHQ were performed, according to published guidelines. A total of 70 patients with hand complaints completed the final version of the MHQ and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire Turkish version (DASH-T) twice, on their first visit and after an interval of 7 days. Visual analog scale (VAS) results for pain intensity and grip strength measurements of the individuals were also taken in both assessments consecutively. RESULTS: Translation and back-translation revealed no major difficulties. The Turkish version of the MHQ met set criteria of reliability and validity. The intraclass correlation coefficient of the test-retest reliability for the 6 subscales ranged from 0.79 to 0.96. The internal consistency of the MHQ, estimated by Cronbach's alpha, ranged from 0.85 to 0.96 for all subscale scores. There were high to moderate correlations between MHQ and DASH scores and VAS and grip strength scores of the injured side. CONCLUSIONS: The Turkish version of the MHQ has excellent test-retest reliability and validity, and it is an adequate and useful instrument for measuring functional disability in hand disorders of Turkish-speaking patients.

Hip-preserving reconstruction of the proximal femur with a vascularized fibula autograft and liquid-nitrogen-treated tumor bearing bone.

A five-year-old boy with Ewing sarcoma of the proximal femur was operated at our institution with limb-sparing surgery and biological reconstruction of the proximal femur with a vascularized fibular autograft. During this procedure, the proximal femur was soaked in liquid nitrogen which was subsequently fixed to the fibular autograft, while the epiphysis of the femoral head was spared. To the best of our knowledge, this is the first report of epiphysis-sparing surgery of the proximal femur via a vascularized fibular autograft surrounded by a liquid nitrogen-treated tumor bearing bone autograft. Three years postoperatively, the patient remains disease-free, has a full weight-bearing extremity with good function, and a remodeled proximal femur with minimal deformity. There are no radiological or clinical signs indicative of femoral head osteonecrosis. In conclusion, hip-sparing biological reconstruction is a successful method of limb preservation as an alternative to tumor endoprostheses.

Neurodynamic mobilization in the conservative treatment of cubital tunnel syndrome: long-term follow-up of 7 cases.

OBJECTIVE: The aim of this case series is to describe the effect of nerve mobilization techniques in the standard conservative management of cubital tunnel syndrome (CTS). METHODS: Seven patients with CTS participated in this study. Inclusion criteria were having grade 1 and grade 2 entrapment neuropathy according to the McGowan grading system and no other neuropathies. In the evaluation, gripping with grip dynamometer; palmar gripping with a pinchmeter; pain level and Tinel sign with visual analog scale; sensibility with Semmes-Weinstein monofilaments; and functional status of the patients with the Turkish version of the Disability of Arm, Shoulder, and Hand Index were performed before starting a rehabilitation program, at the end of the 8-week rehabilitation program, and at 12-month follow-up. The physiotherapy program consisted of cold application, pulsed ultrasound, nerve mobilization techniques, strengthening exercises, postural adaptations, patient education, and ergonomic modifications. RESULTS: Pain; Tinel sign; and Disability of Arm, Shoulder, and Hand Index scores were decreased, whereas grip and pinch strength increased in the observation period for these 7 patients. CONCLUSION: This case series demonstrated that conservative treatment of CTS may be beneficial for selected patients with mild to moderate symptoms. The treatment included neurodynamic mobilizations, including sliding techniques and tensioning techniques, which are thought to enhance ulnar nerve gliding and restore neural tissue mobility. Conservative treatment using neurodynamic mobilization with patient education and activity modification demonstrated some long-term positive results.

Radial Reference Points for Measuring Palmar Tilt and Ulnar Variance on Lateral Wrist Radiographs.

Background: Palmar tilt and ulnar variance are crucial parameters for evaluating the distal radius. Identifying suitable reference points for these parameters on lateral wrist radiographs remains challenging. The purpose of this study was to establish reference points for measuring palmar tilt and ulnar variance on lateral wrist radiographs and to evaluate the reliability of these two parameters using the newly defined reference points. Methods: The distal articular surfaces of 25 cadaver radii were marked at four different locations using thin wires. These bones were radiographed and constant landmarks were recorded. The reliability of the palmar tilt and ulnar variance measurements was assessed using the new reference points and two serial measurements recorded by three observers on 27 standardized lateral wrist radiographs. Results: The reference points for palmar tilt on lateral radiograph were the dorsal and volar end points of the subchondral line. The subchondral line was connected to two of five metaphyseal cortical lines. The reference point for lateral ulnar variance was easily defined on the midpoint of the proximal aspect of the subchondral line. The corresponding posteroanterior central reference point for ulnar variance was at the ulnar corner of the subchondral line. Inter- and intra-observer reliabilities were overall good for the palmar tilt measurements, and excellent for the ulnar variance measurements. Conclusions: Palmar tilt can be determined accurately with a good understanding of the radiographic landmarks on lateral radiographs, and by addressing the problems caused by ulnar inclination of the articular surface of the distal radius. Lateral wrist radiographs can provide a complete picture of the ulnar border of the radius for measuring ulnar variance.
