BACKGROUNDThe reconstructive options for the soft tissues in extremities present serious challenges due to thin non-expendable soft tissues and predisposition to massive edema formation, thus frequently requiring flap cover. This study was undertaken to assess the outcome of a modified version of the sural artery flap with that of propeller perforator flaps for the reconstruction of lower extremities, particularly the heel defects. METHODS This prospective study was conducted on 40 consecutive patients, of which 20 treated with sural artery flap and another 20 with perforator based propeller flap cover for soft tissue reconstruction in extremities based on predefined inclusion criteria. The clinical outcome of the flap was assessed after three months. RESULTSInclusion of the posterior tibial perforators (along with the sural artery and the peroneal artery) was shown to enhance the flap territory. The raising of the flap was quick with minimal blood loss and the modified flap had a wide arc of rotation for reconstruction of the heel defects. The younger patients regained sensation on the flap earlier, while the durability of the fasciocutaneous flap was excellent in the heel weight bearing areas. The success rate was 95% flap take. CONCLUSION Careful selection of the perforator and optimal designing of the flap result in favorable outcomes with the use of local perforator flaps for reconstruction in extremities. It provides predictable clinical outcomes with minimal donor site morbidity, is costeffective, relatively easy technique and requires no special microsurgical setup or instruments.

Background: Crush injuries of the hand sustained from sugarcane juice extracting machines have a unique mechanism of injury and clinical presentation. The severity of the injury can vary from simple skin lacerations to mangling of the hand. We devised a classification for these injuries based on the severity level that has helped with the management. The aim of this study is to determine whether the classification correlates with patient rated outcome score at 6 months. Methods: We prospectively studied 30 consecutive patients with a sugarcane crusher injury of the hand. The patients were classified into Class I, II, III or IV based on our classification and managed accordingly. Patient outcomes were assessed at 6 months after the injury, using the Michigan Hand Outcomes Questionnaire (MHQ). Spearman’s rank correlation test was used to analyse the correlation between the different classes of hand injury and functional outcomes at 6 months following injury (measured using MHQ). Results: The study included 6 patients (20%) with Class I injury, 11 patients (36.6%) with Class II, 9 patients (30%) with Class III and 4 patients (13.4%) with Class IV injury. The mean MHQ scores at 6-month follow-up were 72.3% in Class I, 62.1% in Class II, 52.9% in Class III and 32% in Class IV injuries. An inversely proportional association between the severity grade as per the classification and MHQ scores was noted. Conclusion: Our proposed classification of sugarcane crusher injuries of the hand correlates well with the MHQ score. The use of the classification can help with management and predicting prognosis. In addition, wider use will permit comparison of outcomes between different centres. Level of Evidence: Level IV (Therapeutic)
