ABSTRACT

OBJECTIVE@#To summarize the clinical characteristics, differential diagnosis, and treatment methods of finger flexion contracture caused by three kinds of forearm flexor diseases.@*METHODS@#Between December 2008 and August 2021, 17 patients with finger flexion contracture were treated, including 8 males and 9 females, aged 5-42 years, with a median of 16 years. The disease duration ranged from 1.5 months to 30 years, with a median of 13 years. The etiology included 6 cases of Volkmann's contracture, all of which were flexion deformity of the 2nd to 5th fingers, accompanied by limitation of thumb dorsiflexion in 3 cases and limitation of wrist dorsiflexion in 3 cases; 3 cases of pseudo-Volkmann's contracture, including 2 cases of flexion deformity of middle, ring, and little fingers, and 1 case of flexion deformity of ring and little fingers; 8 cases of ulnar finger flexion contracture caused by forearm flexor disease or anatomical variations, all of which were flexion deformity of middle, ring, and little fingers. Operations such as slide of flexor and pronator teres origin, excision of abnormal fibrous cord and bony prominence, and release of entrapped muscle (tendon) were performed. Hand function was evaluated according to WANG Haihua's hand function rating standard or modified Buck-Gramcko classification standard, and muscle strength was evaluated according to British Medical Research Council (MRC) muscle strength rating standard.@*RESULTS@#All patients were followed up 1-10 years (median, 1.5 years). At last follow-up, 8 patients with contracture caused by forearm flexor disease or anatomical variations and 3 patients with pseudo-Volkmann's contracture achieved excellent hand function, with muscle strength of grade M5 in 6 cases and grade M4 in 5 cases. One patient with mild Volkmann's contracture and 3 patients with moderate Volkmann's contracture without severe nerve damage had excellent hand function in 2 cases and good in 2 cases, with muscle strength of grade M5 in 1 case and grade M4 in 3 cases. Two patients with moderate or severe Volkmann's contracture had poor hand function, with 1 case of muscle strength of grade M3 and 1 case of grade M2, which improved when compared with those before operation. The overall excellent and good rate of hand function and the proportion of patients with muscle strength of grade M4 and above were 88.2% (15/17), respectively.@*CONCLUSION@#The finger flexion contracture caused by different etiology can be differentiated by analyzing the history, physical examination, radiographs, and intraoperative findings. After different surgical treatments, such as resection of contracture band, release of compressed muscle (tendon), and downward movement of flexor origin, most patients have a good outcome.

ABSTRACT

OBJECTIVES@#To summarize our experience with the sural neurofasciocutaneous flap for reconstructing the soft tissue defects over the forefoot distal to the connecting line of midpoints in the metatarsal bones, and to compare the outcomes between the flap for resurfacing the defects distal and proximal to the connecting line.@*METHODS@#The clinical data of 425 sural neurofasciocutaneous flaps for repairing the soft tissue defects in the middle and lower leg, ankle, and foot between Apr. 2002 and Apr. 2020 were reviewed. Based on the connecting line of midpoints of the metatarsals, the sural neurofasciocutaneous flaps were divided into a forefoot group (flaps with furthest edges distal to the connecting line) and a peri-ankle group (flaps with the furthest edges proximal to the connecting line).@*RESULTS@#The partial necrosis rate in the forefoot group (14.5%, 10/69) was significantly higher than that in the peri-ankle group (7.0%, 25/356), with significant difference (P<0.05). Using the flap alone or in combination with a simple salvage treatment, the ratio of successful coverages of the defects was 98.6% (68/69) in the forefoot group, and 97.8% (348/356) in the peri-ankle group, respectively, with no statistical difference (P>0.05).@*CONCLUSIONS@#The sural neurofasciocutaneous flap is a better choice for covering the soft tissue defects over the forefoot distal to the connecting line of midpoints of the metatarsal bones. The survival reliability of the sural neurofasciocutaneous flap reconstructing the soft tissue defect proximal to the connecting line is superior to that of the flap reconstructing the defect distal to the connecting line.

ABSTRACT

Objective:To explore surgical techniques and summarize surgical experience of the paraumbilical flap pedicled with deep inferior epigastric vessels for the repiration of soft tissue defects in pelvic area.Methods:Between August, 2006 and August, 2018, 8 patients with soft tissue defects and bone exposure were treated with paraumbilical flap pedicled with deep inferior epigastric vessels. There were 6 males and 2 females with the average age of 35.3 (range, 12-47) years. The defects were caused by car accident in 5 cases, by high falling injury in 1 case, by soft tissue necrosis after malignant schwannoma resection in 1 case, and by soft tissue necrosis after pelvic operation of open reduction internal fixation in 1 case. The defects located at iliac spine in 5 cases, at tuber ischii in 1 case, and at buttock and perineal region in 1 case. The size of the wounds ranged from 11.0 cm×6.0 cm to 22.0 cm×8.0 cm. The size of the flaps ranged from 13.0 cm×7.0 cm to 29.0 cm×12.0 cm. The followed-up was made by outpatinet service, telephone or WeChat.Results:All flaps survived, and the wound infection was controlled. The followed-up time ranged from 12 to 46 (mean 26) months. All flaps survived uneventfully, and the texture and elasticity of the flaps were good. There were no recurrence of infection, and no ventral hernias occurred in donor sites.Conclusion:The transfer of paraumbilical flap pedicled with deep inferior epigastric vessels is a reliable method to repair large soft tissue defects in iliac spine, perineal region, buttock and tuber ischii.

ABSTRACT

Objective This study is to compare flap-viability-related complications, coverage reach, recon-struction outcomes and donor-mobidities between distally-based peroneal artery perforator-plus fasciocutaneous (DPAPF)flap and distally-based posterior tibial artery perforator-plus fasciocutaneous(DPTAPF)flap for recon-struction of soft-tissue defects over the distal lower leg, ankle and foot, and thus provide evidence for selection of the flaps. Methods Between April, 2002 and February, 2012, 216 and 59 patients underwent the reconstructions with DPAPF flaps(peroneal group)and DPTAPF flaps(posterior tibial group)respectively. We subdivided the distal lower leg, ankle and foot into 12 subregions. In all the patients, flap-viability-related complications and its potential risk factors(including age,sex,etiology,location of top edge,location of pivot point,length and width of both the skin is-land and adipofascial pedicle, length-width ratio, and total length), coverage reach(the subregion in which the most distal part of the reconstructed defect lies),duration of flap elevation and hospital stay were compared between the two groups. In patients with at least 3 months postoperative follow-up, comparative study of reconstruction outcomes, pa-tient's satisfaction with flap appearance and donor-site morbidities were performed between the groups. Results Partial necrosis rate in the peroneal of the posterior tibial group were 12.0 percent versus 20.3 percent,respectively(P> 0.05). Marginal necrosis and overall complication (including partial and marginal necrosis)rates in the peroneal group(1.9 percent and 13.9 percent, respectively)were significantly lower than those in the posterior tibial group (8.5 percent and 28.8 percent,respectively)(P<0.05).Incidence of partial necrosis of the flaps for the defects over subregions 7 to 10 in the peroneal group(7 of 41)was significantly lower than that in the posterior tibial group(2 of 2).There was no difference in reconstruction outcomes and patient's satisfaction with flap appearance in both groups(P >0.05).Incidences of hypertrophic scar,itching and pigmentation at the donor site were significantly lower in the peroneal group(P<0.05). Conclusion DPAPF flap is superior to DPTAPF flap in reliability,safe coverage reach and less donor-site morbidities.The former is recommended as the first choice when local pedicle flaps are considered to recon-struct soft-tissue defects over the distal lower leg,ankle and foot.

ABSTRACT

Objective To compare the effect of distally based perforator-plus sural fasciocutaneous flap for soft tissue reconstruction of the lower leg in pediatric and adult populations.Methods Data of 165 patients treated with distally based perforator-plus sural fasciocutaneous flap between April 2001 and February 2011 were retrospectively reviewed.There were 125 males and 40 females,at age range of 3-78 years.The patients were divided into pediatric group (< 14 years,n =50) and adult group (≥ 17 years,n =115) according to the age.The two groups were compared in terms of flap-viability-related complications (partial necrosis,marginal necrosis and overall complication rate) and their potential risk factors (sex,location of defect,causes of defect,pivot point site and top-edge location).For the patients followed at least 12 months,the reconstruction outcomes,donor-site morbidities(hypertrophic scar,pruritus,pigmentation,numbness of skin graft area and paresthesia of skin graft area),and swelling of the limb were compared between the groups.Results All patients were followed up for 2 weeks to 72 months.Partial necrosis of the flap,marginal necrosis of the flap,and overall complications in pediatric group accounted for 14%,4% and 18% respectively,higher than 11.3%,1.7% and 13.0% in adult group,but the differences were insignificant (P > 0.05).Sex ratio,pivot point site and top-edge location were not significantly different between the groups (P > 0.05).Pediatric group versus adult group presented a significantly lower proportion of pretibial defects,but significantly higher proportions of the defects over the achilles tendon and heel (P < 0.05).A significantly higher proportion of spoke injury and lower proportions of tamp injury and sports injury were observed in pediatric group than in adult group (P <0.05).Reconstruction outcomes were not significantly different between the groups (P > 0.05).Pediatric group versus adult group presented significantly higher incidences of hypertrophic scar and pruritus at the donor site,but a significantly lower incidence of limb swelling (P < 0.05).Conclusion Reliability and repair effect of the distally based perforator-plus sural fasciocutaneous flap are similar between pediatrics and adults,while the pediatrics are more likely to have hypertrophic scar and pruritus at the flap donor site.

ABSTRACT

OBJECTIVE@#To explore the effect of length-width ratio (LWR)on partial necrosis in distally based sural neurofasciocutaneous flap.@*METHODS@#Clinical data and operative pictures of 157 distally based sural neurofasciocutaneous flaps were reviewed and analysed. LWR of the flaps ranged from 2.83:1 to 7.14:1. Based on the LWR of the flaps, the flaps were divided into 5 groups: Group A(LWR≤3:1), Group B(3:10.05). Partial necrosis ratio was higher in Group D than that in Group C(P<0.05). It was lower in the LWR<5:1 group (Group A+Group B+Group C) (6.8%, 6/88) than that in the LWR≥5:1 group (Group D+Group E) (17.4%, 12/69) (P<0.05).@*CONCLUSION@#When LWR of the flap is less than 5:1, probability of partial necrosis occurring in distally based sural neurofasciocutaneous flaps is low, and the flap can survive more reliably. The maximum LWR of the surrival flaps can reach 6-7:1.
