OBJECTIVE: To investigate the clinical effects of the microsurgical treatment for the skin-degloving injury of the whole hand or foot. METHODS: From March 1984 to October 2001, we treated 6 cases of skin-degloving injury of the whole hand and foot. In 2 cases of skin-degloving hands, one was treated with free great omentum transplantation plus skin graft, the other with pedical abdominal S-shaped skin flap as well as mid-thick skin graft. In 4 cases of skin-degloving injury of the foot, 2 cases was repaired with free latissimus dosi musculocutaneous flap, 1 case with distall-based lateral skin flap of the leg and 1 case with free tensor fasciae latae muscle flap. The flap size ranged from 7 cm x 9 cm to 22 cm x 15 cm. One case was operated on the emergency stage, the other 5 cases on the delayed stage. The delayed time ranged from 2 to 14 days with an average of 6.6 days. RESULTS: All the flaps survived. After 1-2 year follow-up, the appearance and function of the hand and the foot were good. CONCLUSION: Microsurgery technique in repairing skin-degloving injury of the whole hand and foot can achieve good results. The keys to success are thorough debridement of the recipient area, appropriate selection of the donor site, good vascular anastomosis and active postoperative rehabilitation.
ObjectiveTo understand the status of life quality and fatigue level in patients with diabetic foot and to explore its influencing factors.
MethodsRandom sampling method was used in collecting the general data of 80 diabetic foot patients from January 2013 to January 2014. The questionnaire of Fatigue Scale-14 and Diabetes Specific Quality of Life Scale were analyzed, and the influencing factors of fatigue and life quality were investigated.
ResultsThe total score mean value of fatigue was 8.63±3.39 and the total score mean value of life quality was 71.00±19.84. The life quality and fatigue in patients with diabetic foot were positively correlated (P ＜ 0.01) .
ConclusionsThe life quality of patients needs to be improved. We should especially pay attention to their mental health and try to meet their psychological needs, in order to ease the patients’ fatigue level and improve their life quality. The key for diabetic foot nursing is to discover and assess the fatigue symptoms of patients with diabetic foot diseases.
Objective To provide the anatomic basis for thedesign of the intermediate dorsal neurocutaneous flap on the foot and to reportthe clinical results. Methods On 32 adult cadaver lower limb specimens perfused with red latex, the origins, diameters, courses, branches, and distributions of the intermediate dorsal cutaneous nerve of the foot and its nutrient vessels were observed. On this anatomic basis, from June 2004 to October2005, 5 flaps were developed and applied to the repair of the soft tissue defect in the feet of 4 patients. Results The intermediate dorsal cutaneous nerve of the foot was found to arise from the superficial peroneal nerve. Crossing the intermalleolar line, it was located 1.3±0.6 cm lateral to the midpoint of the line with a diameter of 2.05±0.56 mm. The nerve stem divided into branches 2.8±1.3 cm distal to the line. They distributed the dorsal skin of the second, third and fourth metatarsal and toe. On average, 5.1 perforators per specimen were identified. At least 3 nutrient vessels were always found in each. They originated from the cutaneous branches of the anterior tibial artery and the dorsalis pedis artery in the proximal end and the dorsalis metatarsal artery in the distal end. They perforated the deep fascia 4.3±0.4 cm proximal to the intermalleolar, 1.6±0.3 cm proximal to the tip of the third toe webspace and 1.5±0.3 cm proximal to the tip of the forth toe webspace, respectively. The external diameters of them were 0.82±0.13, 0.42±0.07 and 0.49±0.09 mm, respectively. The patients were followed up for 4-10 months. All theflaps survived completely. Their appearance and function were satisfactory. Conclusion The distallybased intermediate dorsal neurocutaneousflap on the foot has an abundant blood supply. This kind of flap is especially useful in repair of the soft tissue defect in the foot.
ObjectiveTo systematically review the clinical efficacy and safety of hyperbaric oxygen therapy as adjunctive treatment for diabetic foot ulcers.
MethodsSuch databases as The Cochrane Library (Issue 1, 2014), PubMed, EMbase, CBM, VIP, CNKI and WanFang Data were searched up to January 2014 for randomized controlled trials (RCTs) about hyperbaric oxygen therapy as adjunctive treatment for diabetic foot ulcers. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software.
ResultsFourteen RCTs involving 910 patients were included. The results of meta-analysis showed that, hyperbaric oxygen therapy combined with routine therapy was superior to routine therapy alone regarding ulcer healing rates (RR=2.16, 95%CI 1.43 to 3.26, P=0.000 3), incidence of major amputation (RR=0.20, 95%CI 0.10 to 0.38, P < 0.000 01), reduction of ulcer area (MD=1.73, 95%CI 1.34 to 2.11, P < 0.000 01), and improvement of transcutaneous oxygen tension (MD=14.75, 95%CI 2.01 to 27.48, P=0.02). However, no significant difference was found between the two group in minor amputation rates (RR=0.70, 95%CI 0.24 to 2.11, P=0.53). In addition, neither relevant serious adverse reaction nor complications were reported when using hyperbaric oxygen therapy as adjunctive treatment.
ConclusionCurrent evidence shows that hyperbaric oxygen therapy as adjunctive treatment could improve ulcer healing and reduce incidence of major amputation.
Objective To review the progress in amputation technique of diabetic foot. Methods Recent l iterature concerning the amputation technique of diabetic foot was reviewed and analyzed. Results According to the different levels of the amputation, the diabetic foot’s amputation can be classified as major amputation and minor amputation, and differentkinds of methods can derive from these styles. Different factors should be considered when the style and method of amputation are chosen. Conclusion To the diabetic foot amputation, the general rule is to l imit the amputation level on the premise of the good cl inical effect. The health state, the region of the diabetic foot, the tissue perfusion, the susceptibil ity to infection in local tissue, and the abil ity of wound healing are important factors in selecting the styles and methods of diabetes-related amputations. Importance should be attached to the synthesis treatments of diabetes to prevent the higher level amputation.
Objective To investigate the surgical methods and cl inical results of reconstructing soft tissue defects in dorsum of forefoot with distally based saphenous neurocutaneous flap of lower rotating point. Methods From January 2005 to August 2007, 6 cases of soft tissue defects in dorsum of forefoot, including 4 males and 2 females aged 28-53 years, were treated with the distally based saphenous neurocutaneous flaps of lower rotating point. The soft tissue defect was in left foot in 2 cases and in right foot in 4 cases. Five cases of soft tissue defects were caused by crush, and 1 case was caused by traffic accident. Tendons and bones were exposed in all cases. The defects after debridement were 7.0 cm × 5.0 cm to 9.0 cm × 5.5 cm in size. Emergency operation was performed in 2 cases and selective operation in 4 cases. Rotating point of the flaps was from 1 to 3 cm above medial malleolus. The size of the flaps ranged from 8.0 cm × 6.0 cm to 13.0 cm × 6.5 cm. Neuroanastomosis was performed in 2 cases of the flaps. Skin defects in donor site were repaired with thickness skin graft. Results Four cases of the transferred flaps survived completely and the other 2 cases began to swell and emerge water bl ister from the distant end of the flap after operation, which resulted in distal superficial necrosis of flaps, heal ing was achieved after change dressings and skin grafted. Skin graft in donor site survived completely in all cases. All cases were followed up from 6 to 18 months. The color and texture and thickness of theflaps were similar to reci pient site. Pain sensation and warmth sensation of the 2 flaps whose cutaneous nerve were anastomosed recovered completely, two point discrimination were 8 mm and 9 mm respectively. Sensation and warmth sensation of the 4 flaps whose cutaneous nerve were not anastomosed recovered partly. All patients returned to their normal walking and running activities and no ulceration occurred. No donor site morbidity was encountered. Conclusion Blood supply of the distally based saphenous neurocutaneous flap of lower rotating point is sufficient, the flap is especially useful for repair of soft tissue defects in dorsum of forefoot.
Objective To investigate the clinical efficiency of thedistally based sural island flap and myofasciocutaneous flap in reconstruction of defect and osteomyelitic cavity of the ankle and foot. Methods From June 1997 to October 2004, 21 patients with soft tissue defects and osteomyelitis in the ankle and foot were treated with the distally based sural island flap and myofasciocutaneous flap. There were 20 males and 1 female aging from 6 to 78 years. The defect was caused by soft tissue defect trauma(18 cases) and electrical injury ( 3 cases). Among 21 patients, 17 were treated with island flaps, 4 by the myofasciocutaneous flap. The size of flaps ranged from 4 cm×5cm to 16 cm×22 cm. The donorsites were closed directly in 4 cases. Results The flaps completely survived in 21 cases and healing by first intention was achieved. After a follow-up of 36 months, no complication occurred. The color and texture of the flaps were good. The appearance and the function were satisfactory. Conclusion Distally basedsural flap is a reliable flap. This flap has rich blood supply without sacrifice of major arteries. Flap elevation is easy. It is very useful in repairing large soft tissue defects of the lower leg, the ankle and the foot, especially inrepairing deep soft tissue defects and osteomyelitic cavities .
【Abstract】 Objective To observe the effectiveness of limited operations and Ilizarov techniques for correction of congenital clubfoot (CCF) in adolescents, and to explore the new methods and new ideas for functional reconstruction of CCF. Methods Between September 2003 and July 2010, 25 adolescent patients (40 feet) with CCF were treated. Of the 25 patients, 14 were male (20 feet) and 11 were female (20 feet) with an age range from 12 to 25 years (mean, 15.7 years). The left feet were involved in 4 cases, the right feet in 6 cases, and both feet in 15 cases. According to Qin’s clubfoot deformity scale, 9 feet were rated as degree I, 17 feet as degree II, and 14 feet as degree III. In these cases, 9 feet were accompanied by internal rotation deformities of crus and 1 case by subluxation of right hip joint. After soft tissue release and osteotomy, 9 feet (degree I) were fixed by composite external fixation instruments, 31 feet by Ilizarov external fixation instruments. The deformity was corrected from 5 to 7 days after operation with distraction of 0.5-1.0 mm/d, then distraction stopped when the ankle was corrected at a hyperextension of 5 to 10° and light valgus. The affected limb might undergo weight bearing walking with external fixation at corrected position for 4 to 6 weeks. If one had both feet deformity, staged operation should be performed with a surgery interval of 3 to 6 months (mean, 4 months). Results The fixation time was 6-12 weeks (mean, 8 weeks) in 9 feet fixed by composite external fixation instruments, and it was 6-17 weeks (mean, 13 weeks) in 31 feet fixed by Ilizarov external fixation. All 25 patients were followed up 8 months to 6 years with an average of 37 months. During distraction process, slight pin track infection occurred in 6 cases (6 feet), which were cured after expectant management. One patient had recurrence of the deformity at 2 years postoperatively, who obtained satisfactory correction after Ilizarov external fixation for 4 weeks. The satisfactory correction and foot function were achieved in the other feet with walking on full weight-bearing. According to International Clubfoot Study Group (ICFSG) score, the results were excellent in 28 feet, good in 10 feet, and fair in 2 feet, with an excellent and good rate of 95% at last follow-up. Conclusion Combined limited operation with Ilizarov technique for correcting adolescent CCF is accord with biology principle and minimally invasive surgical principle, so it is a safe，minimally invasive, and effective method. It also can broaden the operative indications and correct degree III talipes equinovarus which is unattainable by traditional orthopedic surgery.
Objective To evaluate the surgical treatment and effectiveness of rheumatoid forefoot reconstruction with arthrodesis of the first metatarsophalangeal joint and arthroplasty of lesser metatarsal heads. Methods Between January 2007 and August 2009, 7 patients with rheumatoid forefoot were treated by reconstruction with arthrodesis of the first metatarsophalangeal joint and arthroplasty of lesser metatarsal heads. They were all females with an average age of 62 years (range, 56-71 years) and with an average disease duration of 16 years (range, 5-30 years). All patients manifested hallux valgus, hammer toe or mallet toe of 2-5 toes, 5 feet complicated by subluxation of the second metatarsophalangeal joint. The improved American Orthopaedic Foot amp; Ankle Society (AOFAS) score was 36.9 ± 6.4. The hallux valgus angle was (46 ± 5)°, and the intermetarsal angle was (12 ± 2)° by measuring the load bearing X-ray films preoperatively. Results All incisions healed by first intention after operation. The X-ray films showed bone fusion of the first metatarsophalangeal joint at 3-4 months after operation. Seven patients were followed up 2.9 years on average (range, 2-4 years), gait was improved and pain was rel ieved. The hallux valgus angle decreased to (17 ± 4)° and the intermetarsal angle was (11 ± 2)° at 3 months postoperatively, showing significant differences when compared with preoperative values (P lt; 0.05). The improved AOFAS score was 85.3 ± 5.1 at 2 years postoperatively, showing significant difference when compared with preoperative score (t=4.501, P=0.001). One patient had recurrent metatarsalgia at 4 years after operation. Conclusion Arthrodesis of the first metatarsophalangeal joint and arthroplasty of lesser metatarsal heads for rheumatoid forefoot reconstruction can correct hallux valgus, remodel the bearing surface of the forefoot, and rel ieve pain, so it can be considered as a procedure that provides improvement in the cl inical outcome.
Objective
To review the progress in clinical and biomechanical study on soft tissue reconstruction of adult-acquired flatfoot deformity (AAFD).
Methods
The recent original articles of soft tissue repair and tendon transfer for AAFD were extensively reviewed.
Results
The soft tissue procedures for AAFD can be divided into two components: static restoration of medial column stability and dynamic reconstruction of the posterior tibial tendon. The most important static structure to be repaired for AAFD is the spring ligament. On the other hand, various methods can be used for dynamic reconstruction. The flexor digitorum longus transfer is widely used, but results of biomechanical studies do not support the advantage of this method. For patients having normal function of the posterior tibial muscle, the Cobb procedure may be more suitable.
Conclusion
The soft tissue reconstruction procedures of AAFD should be chosen individually based on the stage and type of the deformity.
