Effect of Health Care and Rehabilitation Nursing and Analysis of Neurovascular Preservation of Patients Undergoing Reconstruction of Severed Finger under X-ray Image Examination.

OBJECTIVE: The study aimed to provide a guideline for continuous rehabilitation nursing for patients with severe finger replantation, and establish a satellite contact point for patients with severe finger replantation after discharge, so as to ensure scientific and effective rehabilitation training after discharge and explore the role of continuous rehabilitation nursing measurement in severe finger rehabilitation and neurovascular preservation. METHODS: A total of 380 patients accepting neurovascular preservation finger replantation in the hand surgery department were divided into an observation group and a control group according to the number of hospitalizations. All patients underwent reconstructive surgery of severed finger. X-ray filming was used to monitor the postoperative nursing effect of neurovascular preservation of severed finger. The discharged patient information questionnaire was filled 3 days before the discharge. Then, a patient information database was established, and rehabilitation training was performed. Finally, sexual rehabilitation nursing follow-up intervention, telephone follow-up, and cross-referring intervention were carried out. Postoperative x-ray images were taken regularly to observe the recovery of reconstructed finger. RESULTS: There was no difference in daily life ability scores and hand function scores between the 2 groups at discharge (P > 0.05). The daily life ability scores and hand function scores of the observation group were better than those of the control group at 1 and 6 months after discharge (P < 0.05), the difference is statistically significant. As the discharge time prolonged, the daily life ability score and hand function score of the 2 groups of patients gradually increased. X-ray images showed that the replanted finger body was well developed, phalanx was in good antithesis, and there was no epiphysis. CONCLUSIONS: Continuous rehabilitation nursing measures should be taken after the replantation of the severed finger after neurovascular preservation, which provides standardized rehabilitation training standards for patients with replantation of severed finger after discharge, improves patient training compliance, promotes hand function recovery as soon as possible, and enables patients to return to society as soon as possible, which is worthy of clinical promotion and application.

Forefoot Replantation in a 3-Year-Old Boy: Case Report.

Few reports about successful forefoot replantation in children have been published. In this article, we present a case of a 3-year-old boy with severe complete amputation of the left forefoot from a crushed and degloved injury in a motorcycle accident. The replantation was successfully performed, even though total ischemia time lasted 8 hours, of which 4 hours was cold ischemia time. The child was able to walk without significant difficulties from 4 months postoperatively and led a normal life in school at 2 years of follow-up. In this case, we present the replantation of a high-velocity traumatic partial foot amputation in a child with excellent function and cosmetic outcome.

Reconstruction of a Traumatic Partial First-Ray Amputation with the Use of an Induced Pseudosynovial Membrane and Corticocancellous Autograft.

Reconstruction of large bone defects of the metatarsals, whether resulting from trauma, infection, or a neoplastic process, can be especially challenging when attempting to maintain an anatomical parabola and basic biomechanical stability of the forefoot. We present the case of a 42-year-old man with no significant medical history who presented to the emergency department following a severe lawnmower injury to the left forefoot resulting in a large degloving type injury along the medial aspect of the left first ray extending to the level of the medial malleolus. The patient underwent emergent debridement with application of antibiotic bone cement, external fixation, and a negative-pressure dressing. He was subsequently treated with split-thickness skin graft and iliac crest tricortical autograft using a locking plate construct for reconstruction of the distal first ray. Although the patient failed to advance to radiographic osseous union, clinically there was no motion at the attempted fusion site and no pain with ambulation, suggestive of a pseudoarthrosis. The patient has since progressed to full nonpainful weightbearing in regular shoes and has returned to normal activities of daily living. The patient returned to his preinjury level of work and has had complete resolution of all wounds including his split-thickness skin graft donor site. This case shows the potential efficacy of the Masquelet technique for spanning significant traumatic bone defects of the metatarsals involving complete loss of the metatarsophalangeal joint.

Painful Proximally Oriented Large Heterotopic Spur Formation in an Active Adult With a Nontraumatic Amputation.

Heterotopic ossification (HO) is excess bone growth in soft tissues, typically juxta-articular and interfascicular, with varying incidence. This excess bone growth has been well-documented in cases of traumatic amputation but less frequently observed in cases of nontraumatic amputation. Symptomatic heterotopic ossification usually includes pain during prosthetic use with management involving prosthetic adjustments for comfort. This atypical case highlights a patient with a nontraumatic amputation and a proximal-oriented large spur formation that was not painful with ambulation but with doffing his prosthesis.

Mangled finger salvage using cross-finger revascularization.

BACKGROUND: Mangled finger with impaired arteria digitalis communis remains to be a challenge for replantation surgery due to the limited amount of tissue to work with. METHODS: Out of 554 hands with total finger amputations treated by replantation of finger/fingers from July 2012 to June 2018, there were 7 cases of damaged arteria digitalis communis, all of which were replanted by anastomosing distal adjacent radial/ulnar digital artery to distal end of ulnar/radial digital artery of amputation finger, and 2 veins were anastomosed for each finger. A skin pedicle was made by suturing both dorsal and palmar skin of adjacent fingers, and detachment was performed 4 weeks postoperatively. RESULTS: The survival rate was 100%. Mean total active motion was 191.4° (ranging from 170 to 220°). Mean 2-point discrimination was 8 mm static (ranging from 6 to 11 mm), and mean grip strength was 35.3 kg (range, 29 to 40 kg). CONCLUSIONS: Based on our experience, cross-finger revascularization is an effective and safe alternative for mangled finger salvage when arteria digitalis communis is damaged, and good functional prognosis can be expected.

A Rare Case of First Metatarsal Extrusion: Results of Treatment After 12 Months.

We present the case of a 21-year-old male with 12 months' follow-up after reimplantation of a completely extruded first metatarsal. The patient had a motorcycle accident involving his right foot and ankle, with multiple lesser metatarsal fractures, lateral malleolus fracture, and a total first metatarsal extrusion (without fracture) through a large dorso-medial forefoot wound. The extruded bone was recovered at the site of the motor vehicle accident and was transported to the hospital with the patient. Before the reimplantation surgery was undertaken, the first metatarsal was immersed in a chlorhexidine solution for 20 minutes and then washed in an antibiotic solution. Metatarsal fixation was performed with Kirschner wires; the lateral malleolus fracture was fixed with plate and screws. An external fixator was then applied. Throughout the 12-month follow-up period, there was no evidence of infection. At the present time, this case suggests that, after antiseptic cleansing and prompt surgery, extruded first metatarsal reimplantation is possible with a reasonable degree of clinical success.

Use of Three-Dimensional Printing Techniques in the Management of a Patient Suffering From Traumatic Loss of the Talus.

Traumatic loss of the whole talus is extremely rare, and its possible treatment options are limited. Our experience of treatment of a 30-year-old male suffering from traumatic loss of the whole talus with the insertion of an anatomical antibiotic-loaded talus cement spacer using 3-dimensional printing techniques as an interim measure was reviewed and reported. A young motorcyclist was brought to the emergency department after a road traffic accident. He sustained multiple injuries including traumatic loss of his left talus. Despite repeated surgeries of debridement and insertion of external fixator to his injured ankle, the patient had residual problem of ankle instability, ankle infection, and absence of his involved talus. With the help of computerized 3-dimensional printing techniques, an anatomical talus cement spacer was produced in the operating room and inserted into the patient's ankle 7 weeks after the initial trauma. The external fixator was kept for another 3 weeks before removal. At 14 months after the insertion of cement spacer, the patient could walk independently without any pain for 15 minutes with the help of a crutch occasionally. However, the range of motion of his left ankle was limited to 15° in the flexion-extension arc and minimal subtalar motion. The infection of the left ankle was under control.

Arteriography and Histopathology of Vascular Beds in Traumatically Amputated Fingers.

BACKGROUND: The success of replantation following traumatic amputation is determined by the quality of the vascular anastomoses. The purpose of this study was to assess the vascularity of injured arteries from traumatically amputated digits using arteriographic and histopathological analysis. METHODS: 25 amputated digits were included in the study. Crush and avulsion injuries were evaluated according to the Venkatramani classification. The amputated arteries were dissected under a microscope, and the arterial route determined with a transducer. Arteriography using fluoroscopy was evaluated by a radiologist. The area thought to be damaged was dissected and 2-mm slices taken for histopathological examination, and scored using the parameters of fibrin accumulation, oedema, separation, and bleeding. RESULTS: Arterial flow was observed in 6 of 7 in the avulsion group. In the crush group, arterial flow was observed in 11 of 16 cases. On histopathological examination in all cases there were 2 or more findings of either oedema, fibrin formation, bleeding or hernia. These findings were more common in the crush group then the avulsion group. CONCLUSIONS: The intravascular introduction of radio contrast agents to amputated digit prior to replantation may give further information particularly in avulsion amputations.

Laser doppler imaging as additional monitoring after digital replanting: A prospective study.

BACKGROUND: Despite various exisiting monitoring methods, there is still a need for new technologies to improve the quality of post-operative evaluation of digital replantation. The purpose of the study is using a laser Doppler imaging device (Easy-LDI) as an additional tool to assess perfusion. In this method, the changes in the frequency of the laser ligth provide information regarding perfusion of the monitored tissue. PATIENTS AND METHODS: This study included seven patients (10 fingers; age of patients: 21-57 years) who suffered from a total (n = 6) or subtotal amputation (n = 4) due to accidents. In addition to hourly standard monitoring with clinical evaluation and skin thermometry, revascularized fingers were hourly monitored with Easy LDI for 48 h. RESULTS: LDI measurement values ranged between 0.8 and 223 (mean 90.62 ± 21.42) arbitrary perfusion units (APU). The mean LDI values before and after revascularization were 7.1 ± 2.85 and 65.30 ± 30.83 APU, respectively. For the successful revascularized fingers (8 of 10 fingers) values from 19 to 223 APU (mean 98.52 ± 15.48) were demonstrated. All of the replants survived, but due to venous occlusion two digits required revision 12 and 35 h after revascularization, respectively. In the two cases, Easy-LDI also showed a constant and slow decline of the perfusion values. Furthermore, Pearson normalized correlation coefficient showed a positive significant correlation between temperatures of the replants and LDI-values (P < .001, r = +0.392) and a negative significant correlation between Δtemperature and LDI-values (P < .001, r = -0.474). CONCLUSION: The LDI-device might be a promising additional monitoring technique in detection of perfusion disturbance in monitoring digital replantations.

Determination of a threshold compromise value for the perfusion index by laser Doppler imaging after digital revascularization.

We have used laser Doppler imaging to monitor the microcirculation of replanted digits during the post-operative period in 103 patients who underwent either replantation after traumatic amputation or toe-to-finger reconstruction. The blood flow (perfusion unit) in each revascularized digit was compared with that of an unaffected digit. The perfusion index was defined as the perfusion value of a revascularized digit divided by the perfusion value of the neighbouring normal digit. The ideal threshold value of the perfusion index (0.397) was calculated by determining the receiver operating characteristic curve with optimal sensitivity and specificity. The corresponding Youden's index was 0.828. We believe that by establishing a threshold, that laser Doppler imaging should provide a reliable and objective assessment for the development of perfusion compromise in revascularized digits. LEVEL OF EVIDENCE: III.

Computed Tomography Study of the Feet of Mummy of Ramesses III: New Insights on the Harem Conspiracy.

OBJECTIVE: A previous study of the computed tomography (CT) of the neck of mummified Ramesses III (1190-1070 BC) suggested that an assailant slit the Pharaoh's throat with a knife in the plot known as Harem conspiracy. We hypothesized the presence of other injuries in the Pharaoh's body as a result of this fatal attack. METHODS: We analyzed CT images of mummified Ramesses III and reported any finding suggestive of trauma in correlation with archeologic literature. RESULTS: Computed tomographic images show partially amputated left big toe. The bony edges are sharp without signs of attempted healing. The ancient embalmers replaced the missing toe with a linen-made prosthesis and placed 6 metallic amulets (eye of Horus) at the feet region. CONCLUSIONS: The Pharaoh's left big toe was likely chopped perimortem by an assailant using a heavy sharp instrument as an ax. This additional injury supports the plot and gives more information about the death scene.

Skeletal Fixation in a Mutilated Hand.

Hand fracture fixation in mutilating injuries is characterized by multiple challenges due to possible skeletal disorganization and concomitant severe injury of soft tissue structures. The effects of skeletal disruption are best analyzed as divided into specific locales in the hand: radial, ulnar, proximal, and distal. Functional consequences of injuries in each of these regions are discussed. Although a variety of implants are now in vogue, K-wire fixation has stood the test of time and is especially useful in multiple fracture situations. Segmental bone loss is quite common in such injuries, which can be safely reconstructed in a staged manner.

Traumatic Loss of the Ulnar Condyle of the Proximal Phalanx of the Ring Finger Repaired with a Palmar Plate Flap: a Case Report.

We report on an acute, open PIP joint injury to the ring finger with associated loss of the ulnar condyle of the proximal phalanx, which was repaired by the removal of bone fragments and replacement of the bone defect with a proximally based palmar plate flap.

Does Blast Medium Affect Heterotopic Ossification in a Blast-amputation Model?

BACKGROUND: Heterotopic ossification (HO) develops after nearly 2/3 of traumatic blast amputations in the contemporary battlefield. This phenomenon has potentially devastating consequences for servicemen and women and its pathophysiology warrants further investigation using a previously developed animal blast model. QUESTIONS/PURPOSES: We asked, what is the (1) severity (quantity) and (2) type (location) of HO bone formation after a hindlimb blast amputation with two distinct blast media. We hypothesized that a more "war-relevant" blast medium could be a more accurate model and potentially intensify the development of HO. METHODS: Using a Sprague-Dawley rat model, the pathophysiology of ectopic bone formation in a traumatic hindlimb blast amputation was evaluated. Twenty-four animals underwent blast amputations and closure based on a previously established experimental model. Half the amputations were subjected to blasted sand and the other 1/2 to blasted water. Serial orthogonal radiography was performed on each animal until euthanasia at 24 weeks to track the development of HO. Heterotopic bone severity and type were assessed by three independent graders at each time using a novel grading scale to assess quantity and quality of HO. RESULTS: All animals had radiographic evidence of HO develop. No differences were observed in ectopic bone development between sand and water blasting regarding severity or type at any time. Animals that received water and sand blasting had moderate HO develop at 24 weeks (median, 2.0 and 2.5 weeks, respectively; range, 1-3 weeks; difference of medians, 0.5; p=0.67). At the time of euthanasia, 10 animals that were water blasted had Type 3 HO compared with 11 in the sand-blasted group (p=1.00). CONCLUSIONS: Our study showed a clear development of HO after hindlimb blast amputation in a Sprague-Dawley rat model; however, no difference was observed in HO development based on the type of blast media. This suggests it is the blast mechanism that induces ectopic bone development, regardless of the blasted medium. The grading scale we developed for our animal-model study provided a reliable means of assessing HO severity and type. CLINICAL RELEVANCE: We anticipate that future investigations will elucidate similarities between service members' wartime extremity injuries and the animal model used in our study, and with focused future research this model may have beneficial therapeutic implications as the pathophysiology of HO development is further understood.

[Transposition of the Ring Finger after Severe Hand Injury]. / Ringfingertransposition nach schwerem Handtrauma.

We report a severe hand injury with a fracture of the third metacarpal bone, destruction of the metacarpophalangeal joint of the fourth finger, amputation of the little finger of the right hand and several tendon injuries, in an active musician. The fourth metacarpal bone was offset close to the base, the hand narrowed, and the ring finger transferred to the base of the little finger. The outcome was very favourable.

Second-toe transfer for traumatic thumb amputation in children under 5 years: bone and soft-tissue growth.

BACKGROUND: Posttraumatic thumb amputations in children under 5 years are uncommon. The final clinical long-term results have been reported shortly in literature. We report our clinical experience in children under 5 years with traumatic amputation of the thumb that were reconstructed using a second-toe transfer. MATERIALS AND METHODS: There were 7 boys and 2 girls between the ages of 1 and 5 years. The follow-up was between 6 and 14 years. The average age at the time of transfer was 2.8 years, and the average follow-up was 10.7 years (range, between 6 and 14 y). The most frequent cause of amputation was avulsion (33.3%). RESULTS: All the transferred toes survived and achieved bone union and static 2-point discrimination was averaged at 5 mm. They acquired good prehensile pinch and grasp. All of the structures of the transferred toes showed substantial growth. CONCLUSIONS: Second-toe transfer for traumatic amputation of the thumb continues to be one of the best choices. Children require secondary procedures less often and in some cases late functional recovery can be expected. It is a safe procedure and there are fewer complications and a better success rate.

Management of partial traumatic hemipelvectomy.

Partial traumatic hemipelvectomy is a devastating condition. Although by definition the affected limb is not totally transected from the trunk because of retained soft tissue, the reported mortality rate is actually higher than in complete traumatic hemipelvectomy. Between January 2000 and December 2011, a total of 917 patients were admitted to the authors' institution for pelvic fracture. Seven of these patients met the criteria for partial traumatic hemipelvectomy. All 7 patients had multiple associated injuries and met the criteria for Baskett class IV hypovolemic shock on arrival at the emergency department. The amount of bleeding was the greatest issue, and control of hemorrhage and rapid blood transfusion were the initial goals. Abdominal aorta balloon occlusion, laparotomy and packing, and pelvic external fixation were useful to control bleeding. Two patients died during the initial resuscitation phase. Angiography (digital subtraction or computed tomographic) was performed in 4 patients but did not provide any treatment-altering information. Limb preservation was attempted in 2 patients; both of these patients eventually required hindquarter amputation. One patient died, and the second patient survived after a difficult postoperative course. The best results were obtained in 3 patients who underwent completion of the hindquarter amputation within 24 hours of trauma. All patients became wheelchair dependent, and no patient was able to return to work. Early completion of hindquarter amputation after hemorrhaging has been controlled is recommended in patients with partial traumatic hemipelvectomy. Angiography did not prove useful in decision making.
