Comparative analysis of clinical outcomes of fixed-angle versus variable-angle locking compression plate for the treatment of Lisfranc injuries.

BACKGROUND: Fixed-angle locking compression plate (LCP) and variable-angle LCP are utilized for internal fixation of Lisfranc injuries. However, studies regarding the difference of clinical outcomes of these two plates are limited. The purpose of present study was to compare postoperative outcomes between these two plate types in Lisfranc injuries. METHODS: A total of 45 consecutive patients (22 patients with fixed-angle LCP and 23 patients with variable-angle LCP) who underwent surgical treatment for Lisfranc injury were reviewed for this retrospective study. The Foot Function Index (FFI), numerical rating scale (NRS) for pain, development of complications, operative time, and patient satisfaction for current activity were compared. RESULTS: There were no significant differences in FFI and NRS for pain at three months and 12 months following surgery. Postoperative complication rate was similar between two groups. Patients with variable-angle LCP had an 18 min shorter mean length of operation (p = 0.040). Patient satisfaction for current activity was not differ between two groups. CONCLUSIONS: The use of variable-angle LCP for treatment of Lisfranc injuries did not show superiority in functional outcomes, pain, complication rates, or patient satisfaction to fixed-angle LCP, but operative time was shorter with variable-angle LCP. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Comparison of the use of evaporative coolants and ice packs for the management of preoperative edema and pain in ankle fractures: a prospective randomized controlled trial.

INTRODUCTION: The use of evaporative coolants in the management of acute musculoskeletal injury has received increasing attention recently. However, its efficacy compared with conventional cryotherapy in treating injured human subjects remains unclear. The purpose of this study is to compare the efficacy of evaporative coolants with that of ice packs in preoperative management of edema and pain in patients with an ankle fracture. MATERIAL AND METHODS: Sixty-three patients in need of surgical treatment for ankle fracture were randomly assigned to either an evaporative coolant group or an ice pack group. Both treatments were applied for 5 days after injury and outcomes were measured daily. The primary outcome was a reduction in edema as measured by the figure-of-eight-20 method and the secondary outcome was measured by visual analog scale (VAS) for pain. RESULTS: Two-way analysis of variance with repeated measures showed no significant group effect and no significant group-by-time interaction in terms of reduction of edema and VAS score for pain between two groups. No adverse effects were reported in either group. CONCLUSION: Evaporative coolants exhibited comparable efficacy to ice packs in preoperative cryotherapy of ankle fractures without adverse effects. While evaporative coolants are more expensive than ice packs, they can present a viable option for cryotherapy. LEVEL OF EVIDENCE: Level I, prospective randomized study.

Evaluation parameters of graft maturation on second-look arthroscopy following anterior cruciate ligament reconstruction: a systematic review.

PURPOSE: The purpose of this systematic review was to investigate and summarize the evaluation methods of graft maturation on second-look arthroscopy following anterior cruciate ligament (ACL) reconstruction. METHODS: A literature search was performed on articles before December 2017 to identify the literature that has evaluated graft maturation on second-look arthroscopy following ACL reconstruction. Only studies using human grafts, evaluating graft maturation with two or more gross findings were included. Study design, grafts, surgical techniques, follow-up period, evaluation parameters, and categories were compiled. RESULTS: Twenty-eight studies were included in this study. All studies evaluated graft maturation with two or more of the following three findings: graft integrity, tension, and synovial coverage. Two to four categories were used for evaluating each parameter, but the criteria for classification were slightly different for each study. Several studies reported neo-vascularization of grafts and the total maturation score by summing up the scores assigned to each evaluation parameter. Three studies reported that there was no correlation between second-look findings and patient-reported outcomes. CONCLUSIONS: Graft integrity, tension, and synovial coverage were the most frequently evaluated for graft maturation on second-look arthroscopy. However, there is no uniform criterion for evaluation. Therefore, development of a valid, uinform criterion is required. LEVEL OF EVIDENCE: Level IV, systematic review of level I-IV investigations.

Comparison of 2-Octyl Cyanoacrylate Topical Skin Adhesive and Simple Interrupted Nylon Sutures for Wound Closure in Ankle Fracture Surgery.

BACKGROUND: Multiple options are available for closure of incisions in ankle fracture surgery. The aim of our study was to compare postoperative outcomes between conventional simple interrupted nylon sutures and 2-octyl cyanoacrylate as a topical skin adhesive to close the incision after ankle fracture surgery. METHODS: We retrospectively reviewed the records of 367 consecutive patients (174 simple interrupted nylon suture patients and 193 topical skin adhesive patients) who underwent operative treatment for ankle fracture between 2010 and 2015. Development of wound complications, operative time, Olerud-Molander Ankle Score (OMAS), and patient satisfaction with the wound were compared. The demographics between the 2 groups were not different. RESULTS: There were no differences in complication rates ( P = .861), OMAS at 3 months or 12 months following surgery ( P = .897 and .646, respectively) between the 2 types of wound closure. Operative time was 9 minutes shorter when topical skin adhesive was used compared to nylon sutures ( P = .003). Patient satisfaction with their wound was significantly higher in the topical skin adhesive group than the nylon skin suture group ( P = .012). CONCLUSIONS: The use of 2-octyl cyanoacrylate topical skin adhesive for wound closure following ankle fracture surgery was effective, safe, and showed higher patient satisfaction compared to simple interrupted nylon sutures. Although caution should be taken because of the insufficient statistical power of complications, this method was an additional safe option for wound closure in ankle fracture surgery. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Predictors of complication following lower extremity amputation in diabetic end-stage renal disease.

AIM: Patients with diabetic end-stage renal disease (ESRD) are at increased risk of lower extremity amputation (LEA) and postoperative complications compared to those without diabetic ESRD. This study sought to determine the factors that influence complications following LEA in patients with diabetic ESRD. METHODS: A total of 41 patients with diabetic ESRD (total of 46 amputations) who underwent LEA were enrolled in this study. The electronic medical records were retrospectively reviewed to identify the predictors of postoperative complications. The outcomes were divided into three categories: no complications, minor complications (wounds requiring only local care or oral antibiotics), and major complications (requiring surgical intervention, further amputations, or inducing life-threatening morbidities and mortalities). RESULTS: Multivariate logistic regression analysis demonstrated that underlying sepsis (P = 0.007) was the only significant risk factor for major complications, with an odds ratio demonstrating an 8.16 times increased risk of requiring another surgery or mortality compared to those without sepsis. CONCLUSION: Preoperative sepsis is an independent risk factor for major complications after LEA in patients with diabetic ESRD. We advise particular caution when performing LEA in diabetic ESRD patients who are also septic. Early amputation, prior to the development of sepsis, is preferable.
