The deltoid ligament is the primary stabilizer of the ankle joint. Injuries of the deltoid ligament are more frequent than assumed but still are often missed. Inadequate treatment can lead to chronic pain, instability and ankle arthritis. The deltoid ligament is strongly connected to the spring ligament. Patient history and clinical assessment as well as magnetic resonance imaging help identify the injured structures. Treatment options range from immobilization in a cast to ligament reconstruction using a free tendon.  相似文献

Transverse clefts of the oral cavity have significant impacts on both appearance and function. Many methods of repair have been described, but there is no consensus on optimal approach. In addition, dissatisfaction with scars, distortion of appearance, and recurrent deformity have led to complex surgical designs that are difficult to understand and reproduce. We describe a simple approach to repair that is based upon anatomic approximation of lip components and accurate repair of the muscle.Twenty patients underwent repair by the senior author, who devised the approach, and the corresponding author, who adopted it. Eight (62%) patients had right-sided clefts, three (23%) patients had left-sided clefts, and two (15%) patients had bilateral clefts. One patient had an associated branchial cleft remnant, two patients had multiple branchial cleft remnants and tragus deformities, one patient had craniofacial microsomia with microtia, and one patient had a contralateral Tessier 1 cleft. Mean age of the patients at repair was 23 months. All patients achieved normal oral competence, have favorable scars and commissure appearance, and have had no recurrent deformity. None of the patients have required revision.The described surgical approach is reproducible, easy to understand, and can produce favorable outcomes.  相似文献

Background: Women with a BRCA mutation have the option of undergoing prophylactic mastectomy and immediate breast reconstruction; however, the potential negative effects of reconstruction on women’s physical and psychological well-being are unclear. This study aimed to investigate complications, patient-reported pain, health-related quality-of-life (HRQoL) and satisfaction following reconstructive surgery at Oslo University Hospital between 2006 and 2013.

Methods: Data were collected retrospectively from the records of 238 patients. A cross-sectional survey was conducted to collect patient-reported HRQoL and satisfaction with outcome using the Short Form-12 questionnaires and Breast-Q. The self-administered Leeds assessment of neuropathic symptoms and signs was used to assess neuropathic pain.

Results: The majority of participants (89.5%) underwent implant-based breast reconstruction (IBBR); the remainder underwent autologous-tissue breast reconstruction (ATBR). Overall, 28.6% had complications within 30?days of surgery and 14.6% required resurgery because of complications. Women who underwent IBBR had a later onset of complications than those undergoing ATBR. Participants in the survey (n?=?175 of 219, response rate 79.9%) reported similar HRQoL to an age-matched general female population. Few (2.9%) reported neuropathic pain. Patients who underwent IBBR were significantly less satisfied with the reconstructed breast (p?=?.001) and overall outcome (p?=?.02) than those who underwent ATBR, but there were no significant differences in HRQoL scores between the two groups.

Conclusions: Overall, 28.6% of the women had complications within 30?days and 14.6% needed resurgery. Few had neuropathic pain. Women who underwent ATBR were more satisfied with the overall outcome than those who underwent IBBR.  相似文献

The Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) is widely used to predict surgical complications affecting various organs. However, there are few reports about objective evaluation methods for head and neck surgery. In this study, we retrospectively examined the association between POSSUM score and actual surgical complications of head and neck reconstruction surgery. In total, 711 patients who underwent head and neck reconstruction after cancer extirpation between January 2007 and January 2015 were studied. The predicted risk of complications was calculated using the POSSUM score and compared with the actual rate of perioperative complications. Perioperative complications occurred in 178 (25%) patients, comprising systemic complications in 52 (7%) patients, surgical site infection of the head and neck area in 78 (11%) patients and failure of the free flap in 55 (8.8%) patients. When patients were divided into a perioperative complication group and a no-complication group, a significant difference between the two groups was observed in the predicted postoperative rate calculated from the POSSUM score (p?相似文献

Anterior cruciate ligament (ACL) injuries are among the most commonly studied orthopaedic injuries. Despite having an excellent prognosis, complications do occur. The timely recognition and management of complications is imperative to ensure the success of reconstruction. Avoiding such complications requires thorough preoperative planning, proficient technical skills to properly manage intraoperative complications, and an extensive knowledge of possible postoperative complications.  相似文献

目的探讨Billroth-Ⅱ、Roux-en-Y及改良非离断式Roux-en-Y技术在腹腔镜胃癌根治术消化道重建中的应用。方法选取2019年2月至2020年12月间商丘市第一人民医院收治的143例实施腹腔镜胃癌根治术患者进行回顾性分析。根据手术方式分为三组,A组46例患者采用Billroth-Ⅱ吻合,B组49例患者采用Roux-en-Y吻合,C组48例患者采用改良非离断式Roux-en-Y技术吻合,比较三组手术指标以及营养指标、生活质量分级、术后并发症发生率。结果三组吻合时间、总蛋白、前白蛋白、白蛋白和住院时间比较,差异无统计学意义(P> 0.05)。A组术中出血量少于B组、C组,手术耗时、消化道重建时间短于B组、C组,差异均有统计学意义(均P <0.05)。C组手术耗时、术后排气时间和消化道重建时间短于B组,术中出血量少于B组,差异均有统计学意义(均P <0.05)。同时C组术后14dⅠ级率高于A组、B组,术后并发症发生率低于A组、B组,差异均有统计学意义(均P <0.05)。结论三种常见重建方式各具有优劣性,改良非离断式Roux-en-Y吻合术虽操作复杂,不...  相似文献
