ABSTRACT
Objective:To investigate the technique and clinical effect of repairing 2 soft tissue defects on the same finger with a pedicled tandem flap of the first dorsal metatarsal artery and the second toe tibial artery.Methods:From March, 2018 to May, 2020, 8 patients, which were 5 males and 3 females, with 2 soft tissue defects in the same finger, were repaired with the first dorsal metatarsal artery flap in series with the second toe tibial flap. The causes of injury: 4 by crush, 2 by heavy object, and 2 by thermal press. There were 4 defects on index fingers, 2 on middle fingers and 2 on ring fingers. The defects ranged from 2.0 cm×2.5 cm to 2.5 cm×3.0 cm. All defects had exposed bone or tendon at varying degrees and 3 with phalanx fractures. Three patients underwent emergency surgery, the other 5 had sub-emergency surgery which were performed 3 to 5 days after the injury. The size of the flaps was 2.0 cm×2.5 cm to 3.0 cm×3.5 cm. The donor sites were sutured directly in 3 patients and 5 patients received skin grafting. The regular follow-up was performed. The survival of flaps, character, feeling and Total active motion(TAM), recovery of the foot donor area and complications were observed.Results:The operation time ranged from 2.0 to 5.5 hours, with an average of 3.5 hours. No vascular crisis occurred and all flaps survived after the surgery. All patients entered follow-up for 3-20 months, with an average of 8 months. The flaps had a good plump appearance, soft texture, good elasticity, and with a high similarity to the surrounding skin. The TPD of the flaps was 6-15 mm, with an average of 8 mm. The fingers had good flexion and extension functions. The incision in the donor site of the foot healed by first intention. The walking, running and jumping were normal without pain or discomfort.Conclusion:The first dorsal metatarsal artery-second toe tibial artery tandem flap has been used to repair 2 soft tissue defects in same finger. It simplifies the revascularisation of the flap together with exact surgical curative effect.
ABSTRACT
Objective:To investigate the effect of arterialised Flow-through venous flap with palmaris longus tendon in repairing dorsal digit composite tissue defect.Methods:From March, 2010 to December, 2018, 23 cases (23 digits) of dorsal digit composite tissue defect were repaired with arterialised Flow-through venous flap with palmaris longus tendon. There were 17 males and 6 females aged between 23 to 53 (average, 37.2) years old. Causes of injury: 15 cases of strangulation, 5 of electric plane and 3 of thermal crush. Number of injured digit were 1 thumb, 11 index fingers, 9 middle fingers and 2 ring fingers. All of the injured digits had skin and extensor tendon defects with an area of 2.0 cm×1.8 cm-4.2 cm×2.6 cm, and the length of extensor tendon defect was 1.6-2.6 cm. One case had terminal and central tendon insertion defects and 5 suffered with terminal tendon insertion defect. Three cases were repaired by emergency surgery, and 20 were repaired by sub-emergency surgery. All donor sites were directly sutured. The shape, colour, texture, sensation, recovery of digit function and donor site appearance were followed-up at outpatient clinic.Results:The patients were followed-up for 8 to 23 (average, 11) months. The flap was soft, with mild pigmentation and recovery of protective sensation. The range of motion of the proximal and distal interphalangeal joints was 145°-170° (average,162.6°). According to Strickland hand function evaluation method, the results were excellent.Conclusion:The arterialised Flow-through venous flap with palmaris longus tendon is an ideal method in repair of the dorsal digit composite tissue defect.
ABSTRACT
Objective:To observe the effect of repeated, bilateral administration of high-frequency transcranial magnetic stimulation (rTMS) in treating post-stroke dysphagia.Methods:Forty-five persons with post-stroke dysphagia were randomly divided into a bilateral group ( n=14 after one dropout), an affected group ( n=15) and a healthy group ( n=15). All received 30 minutes of conventional swallowing rehabilitation training 5 times a week for 2 weeks from a speech therapist. Those in the affected group also received 5Hz rTMS applied to the motor cortex controlling the suprachyoid muscle group. The bilateral group received the same stimulation bilaterally with the same duration and treatment course. Videofluoroscopy was used to assess their swallowing before and after the 2 weeks of treatment. It was rated using the penetration-aspiration scale (PAS) and the functional swallowing disorder scale (FDS). Surface electromyography was employed to evaluate suprachyoid muscle function. Cortical excitability was assessed by measuring the resting motor threshold (RMT) of the unaffected hemisphere. Results:After the treatment, the average PAS, FDS and muscle function values had improved significantly for all three groups, but significant RMT differences were observed only between the bilateral and the unaffected group. Significant differences in the average FDS and PAS scores were observed after the treatment, as well as significant changes in FDS and muscle function between the affected group and the other two groups. The average FDS scores before and after treatment were significantly different between the unaffected and bilateral group, with the former scoring significantly better than the latter. But no significant differences in the average PAS scores were observed after the treatment.Conclusions:5Hz rTMS of either the unaffected or affected cerebral cortex (or bilateral) can effectively improve the swallowing function of persons with post-stroke dysphagia. Bilateral stimulation has the greatest therapeutic effect, followed by stimulation of the unaffected cerebral cortex.
ABSTRACT
Objective:The defects of thumbs and fingers are common and devastating in hand injuries, which make both physical and mental affecets to the patients. With deeper understanding in anatomy and faster development in micro-surgical techniques, the reconstruction of thumbs and fingers from toes with vascular anastomosis became a mainstream in the hand surgeons. These procedures were acclaimed as methods with desired outcome in function, sensation and aesthetics. However, a multitude of modification is responsible for the lack of normalization. We expects this review would provide a reference in fulfilling the surgical strategies.
ABSTRACT
Objective:To explore the effect of high-frequency and low-frequency transcranial magnetic stimulation (rTMS) on the unaffected pharyngeal motor cortex of dysphagic stroke survivors.Methods:Forty-two stroke survivors with dysphagia were enrolled and randomly divided into a high-frequency stimulation group ( n=14), a low-frequency stimulation group ( n=13), and a sham group ( n=15). All received conventional swallowing training. The high- and low-frequency stimulation groups additionally received 250 pulses of 5Hz or 1Hz rTMS over the cortical representation of the mylohyoid muscle on the unaffected side daily for 2 consecutive weeks. In the sham group, sham rTMS was applied with identical protocols. Before and after the intervention, all subjects were subjected to a videofluoroscopic swallowing study and surface electromyography (sEMG). They were also evaluated using the fuctional dysphagia scale (FDS) and the penetration aspiration scale (PAS). Results:After the intervention, a significant improvement was observed in the average PAS, FDS and sEMG results in both rTMS groups compared with the sham control group. The average FDS score of the high-frequency stimulation group had improved significantly more than that of the low-frequency group.Conclusions:rTMS of the contra-lesional cortical representation of the mylohyoid muscle at either 5Hz or 1Hz can effectively improve dysphagia post-stroke. The higher frequency gives superior results.
