Severity of limb ischemic injury and treatment of popliteal artery injury / 中华创伤骨科杂志

Objective To explore the role of severity of limb ischemic injury in the treatment of popliteal artery injury.Methods A retrospective analysis was conducted of 259 patients with popliteal artery injury who had been treated from January 2002 to December 2014.They were 187 males and 72 females with a median age of 37.6 years (range,from 14 to 68 years).The time from injury to revascularization was from 4 hours to 29 days.According to the Rutherford classification system,the limb ischemic injury was categorized into 4 grades:grade Ⅰ:presence of sense and motion;grade Ⅱ:presence of sense but loss of active motion;grade m:loss of sense or motion;grade Ⅳ:stiffness.For all the patients with injury of grades Ⅰ and Ⅱ,limb salvage was adopted and opening decompression to osteofascial compartment was performed depending on the intraoperative and postoperative limb swelling.For the patients with grade Ⅲ injury,opening decompression to osteofascial compartment was performed to explore the activity of muscles in those with a strong will to preserve their limbs.When the muscle activity was poor but bright red bleeding was found at the broken muscle ends and there were no fish-like changes in muscles,limb salvage was suggested;otherwise amputation was chosen.For all the patients with grade Ⅳ injury,amputation was suggested.Results Of the 146 cases of limb salvages,142 were successful and 4 failed due to uncontrollable infection,giving a total success rate of 54.83％ (142/259).Complete rupture of the popliteal artery occurred in 23 cases,incomplete rupture or tear in 17,contusion and thrombosis in 219.No patient died due to popliteal artery injury or its complications.The patients with injury of grades Ⅰ,Ⅱ,Ⅲ and Ⅳ were respectively 51,88,67 and 53;their success rates of limb salvage were respectively 100.00％ (51/51),96.59％ (85/88),8.96％ (6/ 67) and 0.For the patients whose time from injury to revascularization was ＜ 6 h,6 h to 12 h,13 h to 24 h,25 h to 1 w,and ＞ 1 w,the success rates of limb salvage were respectively 80.77％ (42/52),54.58％ (73/134),20.51％ (8/39),33.33％ (6/18),and 81.25％ (13/16).The 142 patients whose limbs had been salvaged obtained an average follow-up of 31.4 months (range,from 6 months to 8 years).Of them,those with grade Ⅰ injury obtained normal plantar sensation and active ankle flexion and extension.Of the 85 patients with grade Ⅱ injury,all recovered normal or nearly normal plantar sensation,29 achieved partial recovery of active ankle and digital flexion and extension,but the other 56 obtained no recovery of active ankle motion.Of the 6 patients with grade l injury,none obtained recovery of motion function,4 achieved partial recovery of plantar sensation but the other 2 had no recovery.Conclusion The classification of popliteal artery injury into 4 grades according to its severity of ischemic injury can provide helpful guidance to the treatment and prognosis assessment of the popliteal artery injury.

Large flow-through venous flap for salvaging limb on the verge of amputation combined with arterial defect / 中华创伤杂志

Objective To investigate the clinical effects of large flow-through venous flap for salvaging the limb on the verge of amputation complicated with arterial defect.Methods Between March 2012 and January 2015,large flow-through venous flap was used in 10 patients with upper limb on the verge of amputation to reconstruct artery defect and large-area skin and soft tissue defect,including 6 males and 4 females with a mean age of 27.9 years (range,18 to 41 years).Injury was caused by machine crush in 4 patients,twisting belt pulley in 4,and traffic accident in 2.The dimension of skin defect ranged from 6.5 cm× 10.0 cm to 10.5 cm × 18.0 cm (mean,9.0 cm × 12.0 cm).Vascular defect length ranged from 6.0 to 16.0 cm (mean,12.3 cm).Time from injury to operation was 1.5-5.5 h (mean,3.5 h).After operation,flap survival,appearance,texture and sensation were recorded.Upper limb function was evaluated using the standard set up by hand surgery branch of Chinese Medical Association.Results The flap varied in size from 8.0 cm×12.0 cm-12.0 cm ×20.0 cm (mean,10.0 cm × 13.5 cm).One patient was amputated due to severe postoperative infection,and 9 patients were successfully operated.The flap showed small-area necrosis on the distal end in 2 patients,which was cured after dressing change,while survived completely in 7 patients.The donor wounds healed in one stage.After 12-27 months of follow-up (mean,13.7 months),the thickness,texture and appearance of the flap were close to the surrounding normal tissues and the skin protective sensation was restored.The functional results were excellent in 6 patients,good in 2 and poor in 1,with the excellent and good rate of 89％.Conclusion Large flow-through venous flap can reconstruct upper-limb vascular defect while repairing large-area wound,and has advantages of easy operation,less damage to the donor site and good appearance.

Reconstrucción en un tiempo del pabellón auricular en amputación parcial traumática con preservación del pedículo inferior: revisión de la literatura y presentación de dos casos / One-stage auricular replantation in traumatic partial ear amputation with inferior pedicle preservation: review of the literature and presentation of two cases

La amputación parcial traumática del pabellón auricular con preservación del pedículo inferior corresponde a una patología infrecuente. Su reconstrucción incluye el uso de diversas técnicas quirúrgicas. Presentamos dos casos de reimplante inmediato, sin uso de microcirugía, con resultados favorables y sin necesidad de reintervenciones, junto a una revisión de la literatura. La revisión bibliográfica realizada apoya el uso de esta técnica, basándose en la preservación del puente cutáneo bajo el tragus que incluye una rama de la arteria temporal superficial y que sería responsable de la irrigación del reimplante.

Partial auricle amputation with preservation of the inferior pedicle is an unusual pathology. The reconstruction in these cases includes many surgical techniques. We present two cases of immediate replantation, without the use of microsurgery, with favorable outcomes and without need of new interventions. The revision of the literature supports this technique based in the preservation of the cutaneus bridge under the tragus that includes a branch of the superficial temporal artery that is responsible of the perfusion of the reimplant.

Prognostic factors on survival rate of fingers replantation

Objective: To evaluate the factors that influence the survival rate of replantation and revascularization of the thumb and/or fingers. Methods: We included fifty cases treated in our department from May 2012 to October 2013 with total or partial finger amputations, which had blood perfusion deficit and underwent vascular anastomosis. The parameters evaluated were: age, gender, comorbidities, trauma, time and type of ischemia, mechanism, the injured area, number of anastomosed vessels and use of vein grafts. The results were statistically analyzed and type I error value was set at p <0.05 . Results: Fifty four percent of the 50 performed replantation survived. Of 15 revascularizations performed, the survival rate was 93.3%. The only factor that affected the survival of the amputated limb was the necessity of venous anastomosis. Conclusion: We could not establish contraindications or absolute indications for the replantation and revascularization of finger amputations in this study.

Trauma vascular na população pediátrica / Vascular trauma in the pediatric population

CONTEXTO: O trauma vascular na população pediátrica apresenta-se como um desafio único, frente à sua incidência relativamente baixa, mesmo em centros médicos de referência. Devido à fragilidade dos tecidos, ao reduzido tamanho dos vasos e à sua baixa incidência, manifesta-se com taxas significativas de morbidade e mortalidade. OBJETIVO: Descrever e analisar os casos de trauma vascular em pacientes pediátricos admitidos em hospital terciário. MÉTODOS: Por meio de estudo retrospectivo, analisaram-se os casos de trauma vascular em pacientes menores de 18 anos, admitidos de janeiro de 2000 a julho de 2010, levando-se em conta dados demográficos, mecanismos de lesão, traumas associados, tratamentos empregados e complicações. RESULTADOS: Foram estudados 242 pacientes com trauma vascular, sendo 37 (15,2%) pertencentes à população pediátrica. A média de idade foi de 12,5 anos, sendo 81% dos participantes da pesquisa do sexo masculino. Entre os mecanismos de lesão, o trauma penetrante foi o mais comum (57%), seguido do contuso (38%) e do iatrogênico (5%). Das técnicas cirúrgicas empregadas, o enxerto arterial com veia autóloga foi o procedimento mais comum (13 casos). Houve um caso de amputação primária (infrapatelar) e quatro amputações no período pós-operatório precoce (três transfemorais e uma transtársica). Dos 11 pacientes admitidos com lesão de artéria poplítea, a taxa de amputação transfemoral pós-operatória foi de 27,3%. Houve apenas um óbito devido a trauma iatrogênico em lactente hemofílico. CONCLUSÕES: O trauma vascular pediátrico envolve vários desafios técnicos, como o vasoespasmo e o calibre dos vasos. As altas taxas de amputações observadas em pacientes com lesões de artéria poplítea, apesar das tentativas de revascularização, reforçam a gravidade desse tipo de trauma.

BACKGROUND: Vascular trauma in the pediatric population is a unique challenge, mainly due to its relatively low incidence, even in high complexity medical centers. Due to the fragility of the tissues, the small size of vessels and low incidence, it manifests with significant rates of morbidity and mortality. OBJECTIVE: To describe and analyze the cases of vascular trauma in pediatric patients admitted to a tertiary hospital. METHODS: Through retrospective study we analyzed the cases of vascular trauma in patients younger than 18 years, admitted from January 2000 to July 2010, taking into account demographic data, mechanisms of injury, associated injuries, treatment techniques and complications. RESULTS: During the studied period, 242 patients were admitted with vascular trauma, 37 (15.2%) belonging to the pediatric population. The average age was 12.5 years, and 81% of the research participants were male. Related to the mechanisms of injury, penetrating trauma was the most common (57%), followed by blunt (38%) and iatrogenic (5%). Among the surgical techniques employed, arterial bypass with autologous vein was the most common (13 cases). There was a case of primary major amputation (below the knee) and four amputations in the early postoperative period (three transfemoral and one transtarsic). For the 11 patients admitted with popliteal artery injury, the rate of postoperative transfemoral amputation was 27.3%. There was only one death due to an iatrogenic trauma in a hemophilic lactant. CONCLUSIONS: Vascular trauma in pediatric patients involves several technical challenges, such as vasospasm and vessel diameter. The high rates of amputation in patients with popliteal artery injuries, despite attempts of revascularization, reinforce the seriousness of this type of trauma.

Comparison of three grading systems for mangled extremity syndrome: amputation versus salvage / 中华创伤杂志

Objective To compare the values of the mangled extremity syndrome index (MESI), the mangled extremity severity score (MESS) and the limb salvage index (LSI) in deciding amputation or salvage in the management of the mangled extremity syndrome (MES). Methods Clinical data of 353 MES patients including 95 with amputation and 258 with salvage admitted in recent eight years were retrospectively evaluated by using MESI, MESS and LSI, the value of which in deciding amputation or salvage was assessed with receiver operating characteristic ( ROC ). Results There was statistical difference in aspect of mean scores of three grading systems between patients with amputation or salvage (P＜0. 01). For MESI, MESS and LSI, the sensitivities was 89.47%, 85.26% and 83.15% respectively, the specificities was 100%, 96.89% and 96.12% respectively, the coincidence was 97.16%,93.76% and 92.63% respectively, the areas under ROC curves was 0. 924, 0905 and 0. 861 respectively and the cut-off points were equal or over 20, 7 and 6 respectively. Conclusions Three scoring systems are all highly capable of predicting early amputation or not in MES management. The MESI is recommended as a quantitative criterion for determining amputation or salvage.

Analysis on amputation due to severe lower limb injury after earthquake / 中华创伤杂志

Objective To analyze indications,complications and outcomes of amputation.Methods A total of 15 patients undergone amputation in field or at tent hospital were collected for analy-zing injury severity,place where amputation was done,whether open or closed amputation and stitch re-moval time. Results There were 9 males and 6 females.at an average age of 32 years(11-51years).There were 16 amputations including Gustilo IIIB in 2 patients, Gustilo IIIC in 9 and Tscheme Ⅲin 5 according to Gustiln classification or Tscheme classification.Four patients who received amputation in field or at tent hospital developed infection and had to receive amputation again at a higher level on the limb and drainage of open wounds because of a higher infection rate due to the amputation location.Ten patients received first amputation at higher levels with open wound at station hospital but only 2 manifested infected incision.High level amputation with one stage closure was done in 1 patient who was infected and suppurated after operation and even developed bacteremia. Conclusions Infection rate following am-putation 4n field and tent clinics is rather higher,so secondary open amputations should be performed at a higher level as soon as possible.One-time and high-level open amputation plays an important role in treat-ment of severe lower limb injuries following earthquake.

Techniques and results of midfoot amputation / 中华骨科杂志

Objective To summarize the techniques and results of midfoot amputation and discuss the role of the tendon balance in this operation.Methods Twenty-six traumatic midfoot amputions were performed from 1990 to 1999. The amputation level ranged from the base of metatarsal to the Lisfranc's joint. The bone stump should be smooth, round and arc featured, the amputation line needn't pass the joints, four extensor longus tendons were divided into two groups and the groups were weaved each other. Bone stump were drilled a hole through which extensor tendon stumps were re-attached to the bone stump. Anterior tibial tendon could also be re-attached to the front aspect of the bone stump with the above mentioned procedure. In case the navicular could not be preserved, midfoot amputation should be given up. Results Among the group, 15 cases were followed-up 2 to 10 years after operation. No case had equinovarus deformity, all cases could flex ankle dorsally to 0? or more, but 4 cases had painful callus on the stump, and 1 case slight ulceration. The other cases in the group got satisfactory outcomes. Conclusion In terms of midfoot amputation, different amputation level leads to different tendon imbalance. Proper tendon balance and appropriate stump repairing is of importance to reconstruct balanced plantar biomechanics,and then, to achieve good long term result.

Clinical observation of the influence of cigarette smoking on digit replantation / 中华骨科杂志

Objective To analyze the effect of cigarette smoking on replantation of amputed digit, investigate the pathologic mechanism of vascular crisis(VC) caused by smoking. Methods 1)The replantation risk factor such as smoking to VC and blood insufficiency of replanted digit was reviewed in 1 685 cases of digit replantation. 2)The complications after digit replantation in short and long terms among patients smoking were compared with those not smoking after operation. The results of management and time of appearance VC was assayed. 3)The possible pathologic mechanism of VC caused by smoking was analyzed. Results 1)A significant correlation between the ratio of VC, blood insufficiency of replanted digit and smoking index(SI, the number of cigarette in a day multiplies the years of smoking) was found. 2)The rate of VC, wound infection and unhealing in short term and the feeling of pain, numbness and cool in the long term in patients smoking after operation (92.6%,55.6%,48.1% and 71.6%) was obviously more than that in non smoking patients(17.8%,9.3%,2.0% and 3.0%,P
