Post-traumatic soft tissue defects sometimes require sequential flap coverage to achieve complete healing. In the era of propeller flaps, which were developed to reduce donor site morbidity, Feng et al. introduced the concept of the free-style puzzle flap, in which a previously harvested flap becomes its own donor site by recycling the perforator. However, when a perforator cannot be found with a Doppler device, we suggest performing a new type of flap, the flip-flap puzzle flap, which combines two concepts: the free-style puzzle flap and the flip-flap flap described by Voche et al. in the 1990s. We present the cases of three patients who achieved complete healing through this procedure.

PURPOSE: The clinical characteristics and results of femoropopliteal artery injury (FPAI) remain unclear. In this study, we evaluated the outcomes and risk factors of limb loss in patients treated for FPAI. MATERIALS AND METHODS: We retrospectively reviewed data from a database of patients who underwent revascularization for an FPAI at a single institution between January 2013 and December 2017. We reviewed and analyzed the characteristics, postoperative results, and factors that influence amputation rates. RESULTS: Twenty-four femoropopliteal arterial reconstructions in 24 patients were included in this study. Among the patients were 20 (83.3%) male with a first-quartile age of 28 years and a third-quartile age of 45 years (range, 15–68 years). The mean injury severity score (ISS) was 16 (range, 4–55), and 5 patients (20.8%) had ISSs of >20 points. The mean mangled extremity severity score (MESS) was 3.8 (range, 1–11), and 8 patients (33.3%) had MESSs of >5 points. In terms of arterial reconstruction methods, autogenous saphenous vein grafting, vein patching, and primary closure were performed in 9 patients (37.5%), 4 patients (16.7%), and 11 patients (45.8%), respectively. Despite arterial reconstruction, 5 patients (20.8%) underwent above-knee amputation. ISSs of >20, MESSs of >7, and orthopedic fixation were statistically significant factors associated with amputation. CONCLUSION: In cases of FPAI with ISSs of >20, MESSs of >7, and orthopedic fixation, amputations should be considered. We were also careful to attempt limb salvage in such cases.

Congenital cystic lymphatic malformations on the extremities are very rare. The patient described in this case study presented with a cutaneous and pedicled macrocystic lymphatic malformation that was eliminated by electrocauterization. A 4-day-old female infant with a congenital cutaneous mass on the dorsal area of her left first metacarpophalangeal joint presented to an outpatient clinic. An electrocautery device was used to cut the pedicle gently with minimal bleeding to avoid mass rupture and to minimize morbidity. A simple wet dressing was applied for 1 week, and the wound subsequently healed completely. Cutaneous macrocystic lymphatic malformations are very rare, especially on the extremities, and no consensus exists on their treatment, which has not been previously described. This report presents this rare case, along with a review of the literature.

The development of microsurgical techniques has also increased the success rate of replantation surgery. This paper reports the results of limb replantation performed on a lower extremity amputation that was associated with crush amputation and an ipsilateral comminuted fracture in and elderly patient. A 68-year-old female presented with a right distal tibia amputation due to a traffic accident. At that time, with a comminuted fracture in the distal femoral condyle, simple wound repair was recommended, but the caregivers strongly wanted replantation. Three years after surgery, normal walking was possible without a cane and the patient was satisfied with the function and aesthetics. What used to be contraindicated in limb replantation in the past are now indications due to the development of microsurgical techniques, surgical experience, and postoperative rehabilitation treatment. If the patient is willing to be treated, good results in contraindications can be obtained.

Open fractures require infection prevention, injured soft tissue management, and fracture fixation. Moreover, it should be treated according to the emergency surgery. The main goals of treatment are life preservation, limb preservation, infection prevention, and functional restoration. Treatment procedure is carried out in the following order. Early diagnosis and management in the emergency room, appropriate antibiotic treatment, adequate irrigation and thorough debridement, fracture fixation and wound restoration (temporary stabilization of the fracture and covering of the wound, definite fixation of the fracture and soft tissue coverage). Herein, we discuss the current trends in each treatment phase to be helpful to other clinicians regarding the applicability of these steps in clinical practice.

BACKGROUND: The current study assessed a recently developed resuscitation protocol for bleeding trauma patients called the Targeted Transfusion Protocol (TTP) and compared its results with those of the standard Massive Transfusion Protocol (MTP). METHODS: Per capita utilization of blood products such as packed red blood cells (RBCs), fresh frozen plasma (FFP), and platelet concentrates was compared along with mortality rates during two 6-month periods, one in 2011 (when the standard MTP was followed) and another in 2014 (when the TTP was used). In the TTP, patients were categorized into three groups based on the presence of head injuries, long bone fractures, or penetrating injuries involving the trunk, extremities, or neck who were resuscitated according to separate algorithms. All cases had experienced motor vehicle accidents and had injury severity scores over 16. RESULTS: No statistically significant differences were observed between the study groups at hospital admission. Per capita utilization of RBC (4.76 ± 0.92 vs. 3.37 ± 0.55; P = 0.037), FFP (3.71 ± 1.00 vs. 2.40 ± 0.52; P = 0.025), and platelet concentrate (1.18 ± 0.30 vs. 0.55 ± 0.18; P = 0.006) blood products were significantly lower in the TTP epoch. Mortality rates were similar between the two study periods (P = 0.74). CONCLUSIONS: Introduction of the TTP reduced the requirements for RBCs, FFP, and platelet concentrates in severely injured trauma patients.

PURPOSE: Varicose veins with great saphenous vein (GSV) insufficiency is prevalent. Among various surgical treatments for varicose veins, cryosurgery of GSV is an alternative minimally invasive technique that could leave fewer scars and replace conventional stripping with ambulatory phlebectomy. This study sought to assess outcomes including efficacy and safety of cryosurgery for varicose veins. METHODS: One hundred thirty-one limbs in 84 patients (37 male, 47 female; mean age, 53.3 years) with varicose veins were treated with cryosurgery over a 2-year period. The patients were followed for postoperative complication with surveillance of recurrence. The analyzed variables included age, sex, symptom, operative time (from skin incision to the application of elastic bandages on the legs for compression purposes), and postoperative complications including bruising, hematoma, superficial thrombophlebitis, cellulitis, seroma, cutaneous nerve damage, and wound complication. RESULTS: The mean operative time was 64.7 minutes for both limbs and 44 minutes for single limbs. The median number of incisions was 2. For stripping of GSV, one incision at the groin was necessary. Postoperative complications included an episode of hematoma in 3 limbs (2.3%), cutaneous nerve damage in 3 limbs (2.3%), cellulitis in 2 patients (1.5%), and seroma in 1 limb (0.8%). No wound infection, thrombophlebitis or deep venous thrombosis was observed. During follow-up (mean follow-up period, 13.5 months; range, 3–28 months), there was no recurrence. CONCLUSION: Cryosurgery to treat varicose veins is an effective and safe treatment modality in terms of postoperative complication, cosmetic result, and recurrence.

OBJECTIVE: Recently, the number of patients who fell or jumped from bridges over Han River has rapidly increased. However, the injury patterns and outcomes of these patients have been poorly characterized. The aim of this study was to determine the injury characteristics of these patients. METHODS: We reviewed the medical records of all patients who were transferred to the Emergency Room due to jumping or falling from bridges over Han River between 2011 and 2015. RESULTS: A total of 203 patients were included. Among them, 14 (6.9%) patients were dead on arrival, 51 (25.1%) patients were expired in the hospital, and 138 (70%) patients were discharged alive, including a patient who had severe neurologic sequelae after resuscitation. Skeletal and internal organ injuries were identified based on radiologic images. The most injured organ was thorax (58.1%), followed by spine (23.1%), abdomen (11.1%), extremity (7.7%), and cranium (5.2%). Chest tubing for pneumothorax or hemothorax was performed in four (2.9%) patients. Surgical intervention was needed for four patients (2.9%). CONCLUSION: Trauma patterns were concentrating on the thorax and spine regions. Therefore, complete radiographic evaluation should be performed for these patients.

OBJECTIVE: To investigate the relationship between motor evoked potential (MEP) response and the severity of motor paralysis, evaluated according to the Korean disability evaluation system in patients with spinal cord injury (SCI). METHODS: We analyzed 192 lower limbs of 96 SCI patients. Lower limbs were classified according to their motor scores, as determined by the International Standards for Neurological Classification of Spinal Cord Injury: motor score <10 (group 1); ≥10 and <15 (group 2); ≥15 and <20 (group 3); and ≥20 (group 4). MEP responses were classified as ‘normal’, ‘delayed’ or ‘absent’, based on their onset latency, which was compared between the different motor score groups. RESULTS: MEP responses and limb motor scores were highly correlated (p<0.001). There was a significant difference of MEP responses between the motor score groups (p<0.001). MEP response was markedly poorer in motor group 1 (limb motor score <10) than in the other three groups (p<0.0001). However, there were no differences between the three groups with motor scores of 10 or above. CONCLUSION: Clinical utility of MEP as a complimentary tool to manual muscle tests could be limited to discriminating motor score groups with severe paralysis, i.e., single lower limb motor power grades of 0 or 1, and from grade 2, 3, and 4, or above, in the Korean disability evaluation system.

BACKGROUND: In cases of total knee arthroplasty (TKA) threatened by potential hardware exposure, flap-based reconstruction is indicated to provide durable coverage. Historically, muscle flaps were favored as they provide vascular tissue to an infected wound bed. However, data comparing the performance of muscle versus fasciocutaneous flaps are limited and reflect a lack of consensus regarding the optimal management of these wounds. The aim of this study was to compare the outcomes of muscle versus fasciocutaneous flaps following the salvage of compromised TKA. METHODS: A systematic search and meta-analysis were performed to identify patients with TKA who underwent either pedicled muscle or fasciocutaneous flap coverage of periprosthetic knee defects. Studies evaluating implant/limb salvage rates, ambulatory function, complications, and donor-site morbidity were included in the comparative analysis. RESULTS: A total of 18 articles, corresponding to 172 flaps (119 muscle flaps and 53 fasciocutaneous flaps) were reviewed. Rates of implant salvage (88.8% vs. 90.1%, P=0.05) and limb salvage (89.8% vs. 100%, P=0.14) were comparable in each cohort. While overall complication rates were similar (47.3% vs. 44%, P=0.78), the rates of persistent infection (16.4% vs. 0%, P=0.14) and recurrent infection (9.1% vs. 4%, P=0.94) tended to be higher in the muscle flap cohort. Notably, functional outcomes and ambulation rates were sparingly reported. CONCLUSIONS: Rates of limb and prosthetic salvage were comparable following muscle or fasciocutaneous flap coverage of compromised TKA. The functional morbidity associated with muscle flap harvest, however, may support the use of fasciocutaneous flaps for coverage of these defects, particularly in young patients and/or high-performance athletes.
