To investigate the correlation between perceived performance in prioritized activities and physical conditions related to grip reconstruction.
Retrospective clinical outcome study.
Forty-seven ...individuals with tetraplegia were included in the study. Each participant underwent tendon transfer surgery in the hand between November 2002 and April 2009 and had a complete 1-year follow-up.
Functional characteristics and performance data were collected from our database and medical records. Patients' perceived performances in prioritized activities were recorded using the Canadian Occupational Performance Measurement. Preoperative data included age at surgery, time since injury, severity of injury, sensibility and hand dominance. At 1-year follow-up, grip strength, key pinch strength, finger pulp-to-palm distance, distance between thumb and index finger and wrist flexion were measured. Correlation rank coefficient was used to test the possible relationship between physical data and activity performance.
There were improvements in both functional factors and in rated performance of prioritized activities after surgery. There was no correlation between performance change and any of the physical functions, the factors known before surgery, or the functional outcome factors.
No correlation exists between a single functional outcome parameter and the patients' perceived performance of their prioritized goals in reconstructive hand surgery in tetraplegia.
Abstract
Objective
Several nerve transfers have now been successfully performed for upper limb reanimation in tetraplegia. This study was performed to review the use of nerve transfers for upper ...limb reanimation in tetraplegia.
Methods
Medline and Embase (1950 to February 11, 2015) were searched using a search strategy designed to include any studies that reported cases of nerve transfer in persons with cervical spinal cord injury (SCI).
Results
A total of 103 manuscripts were selected initially and full-text analysis produced 13 studies with extractable data. Of these manuscripts, 10 reported single cases and 3 reported case series. Eighty-nine nerve transfers have been performed in 57 males and 2 females with a mean age of 34 years. The mean SCI level was C6 (range: C5–7), time to surgery post-SCI was 19.9 months (range: 4.1–156 months), and follow-up time was 18.2 months (range: 3–60 months). All case reports recorded a Medical Research Council (MRC) score of 3 or 4 for recipient muscle power, but two early case series reported more variable results.
Conclusion
This review documents the current status of nerve transfer surgery for upper limb reanimation in tetraplegia and summarizes the functional results in 59 cases with 89 nerve transfers performed, including 15 cases of double-nerve transfer and 1 case of triple-nerve transfer.

Retrospective investigation of medical history, diagnostics, surgeries, and outcomes of surgical treatments of CTS in patients with para- and tetraplegia.
We identified a total of 77 surgeries for CTS in 55 patients: 16 females (25 surgeries) and 39 males (52 surgeries) with spinal cord injury. The majority (47 persons, 68 surgeries) were paraplegic (level of lesion Th2 and below); 8 persons (9 surgeries) were tetraplegic (level of lesion Th1 and above). ASIA scores in the tetraplegic group were A: 0, B: 1, C: 4, D: 3 while complete lesions predominated in the paraplegic group (A: 32, B: 4, C: 5, D: 6). Sixty-six out of 77 patients reported total relief of symptoms. Neither nerve conduction velocity nor motor amplitude correlated well with the severity of CTS. Co-morbidity and specific risk factors were rare.
SCI patients with CTS respond well to surgical decompression of median nerve regardless of level and type of spinal cord lesion and risk factors. Nerve conduction parameters and clinical findings can provide additional diagnostic support of CTS although nocturnal hand paresthesia, wrist pain at and after loading as well as failed conservative treatment are the main indications for surgical interventions. Based on symptomatology, clinical findings, and nerve conduction studies, we propose a decision-making tree for suggesting surgery or not.
Purpose Reconstruction of grasp is a high priority for tetraplegic patients. Restoration of finger flexion by surgical activation of flexor digitorum profundus can result in roll-up finger flexion, ...interphalangeal (IP) joint before metacarpophalangeal (MCP) joint flexion, which can be improved by restoring intrinsic function. This study compares grasp kinematics between 2 intrinsic balancing procedures—Zancolli-lasso and House. Methods The intrinsic muscles of 12 cadaver hands were reconstructed by either the Zancolli-lasso or the House procedure (n = 6 each) and tested by deforming the flexor digitorum profundus (FDP) with a motor to simulate hand closure. Results were compared with 5 control hands. All 17 hands were studied by video analysis. Kinematics were characterized by the order of MCP joint and IP joint flexion. Optimal grasp was defined as the maximal fingertip-to-palm distance during the arc of finger closure. Results Kinematics differed between the 2 procedures. The Zancolli-lasso reconstructed hands flexed first in the IP joints, and then in MCP joints, resembling an unreconstructed intrinsic-minus hand whereas the House reconstructed hands flexed first in the MCP joints and then in the IP joints, resembling an intrinsic-activated hand. Maximal fingertip-to-palm distance did not differ significantly between the 2 procedures, and both showed improvement over unreconstructed controls. Conclusions Both intrinsic balancing techniques improved grasp. Only the House procedure restored hand kinematics approximating those of an intrinsic-activated hand. Improvement in fingertip-to-palm distance in Zancolli-lasso hands resulted primarily from the initial resting MCP joint flexion of 40°. We therefore advocate the more physiological House procedure for restoration of intrinsic function in tetraplegic patients. Clinical relevance This study provides a rationale for advocacy of 1 reconstructive procedure over another.
De Quervain disease is a common pathology resulting in pain caused by resisted gliding of the abductor pollicis longus and extensor pollicis brevis tendons in the fibro-osseous canal. In a situation ...of wavering assumptions and expanding medical knowledge, a treatment guideline is useful because it can aid in implementation of best practices, the education of health care professionals, and the identification of gaps in existing knowledge.
The aim of this study was to achieve consensus on a multidisciplinary treatment guideline for de Quervain disease.
A Delphi consensus strategy was used.
A European Delphi consensus strategy was initiated. A systematic review reporting on the effectiveness of surgical and nonsurgical interventions was conducted and published and was used as an evidence-based starting point for this study. In total, 35 experts (hand therapists and hand surgeons selected by the national member associations of their European federations and physical medicine and rehabilitation physicians) participated in the Delphi consensus strategy. Each Delphi round consisted of a questionnaire, an analysis, and a feedback report.
Consensus was achieved on the description, symptoms, and diagnosis of de Quervain disease. The experts agreed that patients with this disorder should always receive instructions and that these instructions should be combined with another form of treatment and should not be used as a sole treatment. Instructions combined with nonsteroidal anti-inflammatory drugs (NSAIDs), splinting, NSAIDs plus splinting, corticosteroid injection, corticosteroid injections plus splinting, or surgery were considered suitable treatment options. Details on the use of instructions, NSAIDs, splinting, corticosteroid injections, and surgery were described. Main factors for selecting one of these treatment options (ie, severity and duration of the disorder, previous treatments given) were identified. A relationship between the severity and duration of the disorder and the choice of therapy was indicated by the experts and reported in the guideline.
One of the limitations of a Delphi method is its inability to forecast future developments. It investigated current opinions of the treatment of people with de Quervain disease.
This multidisciplinary treatment guideline may help in the treatment of and research on de Quervain disease.

BACKGROUND:Multidisciplinary treatment guidelines for Dupuytren disease can aid in optimizing the quality of care for patients with this disorder. Therefore, this study aimed to achieve consensus on ...a multidisciplinary treatment guideline for Dupuytren disease.
METHODS:A European Delphi consensus strategy was initiated. A systematic review reporting on the effectiveness of interventions was conducted and used as an evidence-based starting point for this study. In total, 39 experts (hand surgeons, hand therapists, and physical medicine and rehabilitation physicians) participated in the Delphi consensus strategy. Each Delphi round consisted of a questionnaire, an analysis, and a feedback report.
RESULTS:After four Delphi rounds, consensus was achieved on the description, symptoms, and diagnosis of Dupuytren disease. No nonsurgical interventions were included in the guideline. Needle and open fasciotomy, and a limited fasciectomy and dermofasciectomy, were seen as suitable surgical techniques for Dupuytren disease. Factors relevant for choosing one of these surgical techniques were identified and divided into patient-related (age, comorbidity), disease-related (palpable cord, previous surgery in the same area, skin involvement, time of recovery, recurrences), and surgeon-related (years of experience) factors. Associations of these factors with the choice of a specific surgical technique were reported in the guideline. Postsurgical rehabilitation should always include instructions and exercise therapy; postsurgical splinting should be performed on indication. Relevant details for the use of surgical and postsurgical interventions were described.
CONCLUSION:This treatment guideline is likely to promote further discussion on related clinical and scientific issues and may therefore contribute to better treatment of patients with Dupuytren disease.
Tendon transfer is a surgical technique for restoring upper limb motor control in patients with cervical spinal cord injuries (SCI), and offers a rare window into cortical neuroplasticity following ...regained arm and hand function.
Here, we aimed to examine neuroplasticity mechanisms related to re-established voluntary motor control of thumb flexion following tendon transfer.
We used functional Magnetic Resonance Imaging (fMRI) to test the hypothesis that restored limb control following tendon transfer is mediated by activation of that limb's area of the primary motor cortex. We examined six individuals with tetraplegia who underwent right-sided surgical grip reconstruction at Sahlgrenska University Hospital, Sweden. All were right-handed males, with a SCI at the C6 or C7 level, and a mean age of 40 years (range = 31-48). The average number of years elapsed since the SCI was 13 (range = 6-26). Six right-handed gender- and age-matched control subjects were included (mean age 39 years, range = 29-46). Restoration of active thumb flexion in patients was achieved by surgical transfer of one of the functioning elbow flexors (brachioradialis), to the paralyzed thumb flexor (flexor pollicis longus). We studied fMRI responses to isometric right-sided elbow flexion and key pinch, and examined the cortical representations within the left hemisphere somatomotor cortex a minimum of one year after surgery.
Cortical activations elicited by elbow flexion did not differ in topography between patients and control participants. However, in contrast to control participants, patients' cortical thumb flexion activations were not topographically distinct from their elbow flexion activations.
This result speaks against a topographic reorganization in which the thumb region regains thumb control following surgical tendon transfer. Instead, our findings suggest a neuroplastic mechanism in which motor cortex resources previously dedicated to elbow flexion adapt to control the thumb.

Surgical reconstruction after quadriplegia represents a powerful solution to restore lost function by injury. A case is presented in which surgical reconstruction of a patient with a C4 level spinal ...cord injury is performed using the brachialis (BRA) muscle as the donor.
The patient previously had no hand function. This transfer, in combination with fusion of the thumb CMC joint and transfer of the flexor pollicis longus (FPL) tendon to the radius, gives the patient full thumb key pinch powered by BRA transferred to the wrist extensors. Theoretical analysis of muscle architectural properties demonstrates that the BRA has sufficient force and excursion to substitute for both the long and short radial wrist extensors. Furthermore, based on the fact that the BRA has almost twice the excursion compared to the extensor carpi radialis longus (ECRL), wrist extension can occur throughout the entire wrist and elbow ranges of motion. Finally, peak tension is lower than the rupture tension previously measured by us using this type of tendon-to-tendon attachment technique, suggesting that the transfer itself is safe and, importantly, can be immediately mobilized for neuromuscular rehabilitation.
This procedure can thus restore tremendous functional capacity in patients who were previously categorized as group 0 by the International Classification of Hand Surgery in Tetraplegia (ICSHT). We suggest that, based on the BRA being an excellent donor for surgical reconstruction, that the ICHST system be reconsidered.
This Landscape review represents our summary of what makes a great collaboration between a surgeon and a scientist. At first, with no perspective, such a collaboration seems easy and natural. But as ...time goes on, with more perspective, you realize how special it is. Now, in our 60s, with ~35 years of collaboration and 75 coauthored papers (most of them in
The Journal of Hand Surgery
), we are both thankful and humbled for this tremendously fruitful and, importantly, very fun collaboration. We are not so foolish to think that we made this great collaboration—it was a gift. However, we now recognize many of the characteristics that make it great and have developed the following ten tips.
Purpose To compare active and passive reconstructive procedures for tetraplegia and their ability to produce a powerful grip and allow appropriate finger extension in a cadaveric model. Methods ...Seventeen fresh-frozen hands were used, which included 5 in intrinsic minus and intrinsic activation conditions, 6 with Zancolli-lasso tenodeses, and 6 with modified House tenodeses to simulate intrinsic function. To test grip, flexor digitorum profundus tendons were powered with a motor. Polyvinyl chloride cylinders of diameters 43, 51, 57, 70, or 89 mm and masses 250, 400, or 550 g were used. Grip was considered successful if the cylinder was grasped and resisted gravity. Finger extension was tested by powering the extensor tendons in the same hands. Results No successful grasps were recorded in the intrinsic minus hands for larger diameter cylinders (≥70 mm), whereas multiple successes were seen after intrinsic activation and after Zancolli-lasso and House procedures. Whereas active intrinsic and the House reconstruction reached near full extension, this was not true for the Zancolli-lasso group. Conclusions These data demonstrated that active and passive intrinsic reconstruction methods improved basic grasp and release kinematics in experimental cadaver hand models. Using our model and based on the more optimal kinematics and full extension of the House procedure, we suggest that this should be the preferred tenodesis-based intrinsic reconstruction method. Nevertheless, both procedures were equally successful at grasping objects of the sizes and masses studied. Clinical relevance Comparative clinical studies are indicated to corroborate the findings of this cadaveric hand model.
