  • Background: We conducted a systematic review of the literature to investigate the correlation between the interval to treatment and management of tendon avulsion ruptures in the musculotendinous junction (MTJ) of the forearm. Methods: A thorough literatures search for studies of tendon avulsion injuries at the forearm was conducted using PubMed, MEDLINE, CINAHL, and Cochrane databases in accordance with the PRISMA guidelines. In total, five case series and 15 case reports accounting for 87 injured tendons involving 60 patients were selected for the analysis. Results: Twenty-six patients had 44 tendon injuries associated with avulsion amputations, 31 patients had 38 tendon ruptures associated with closed avulsion injuries and three patients had five tendon ruptures associated with open avulsion injuries. Eighteen of the 49 (37%) patients were immediately treated for tendon ruptures and one of the 32 (3%) tendon ruptures treated via elective surgery was directly repaired. Additionally, 18 of the 30 (60%) tendons were directly repaired and 12 of the 30 (40%) tendons were transferred or side-to-side repaired in the immediately treated series. In contrast, one of the 28 (4%) tendon ruptures were directly repaired and 27 of the 28 (96%) tendons were transferred or side-to-side repaired in the electively treated series. Conclusion: In managing digital tendon avulsions at the MTJ, an immediate treatment could provide an opportunity to repair the ruptured tendon directly to the muscle.

  • We evaluated forty cases of traumatic diaphragmatic ruptures that we have experienced from Mar. 1976 to Mar. 1992. Thirty patients were male and 10 were female[M:F=3:1]. The age distribution was ranged from 2 to 76 years with the mean age of 35 years. The traumatic diaphragmatic ruptures were due to blunt trauma in 26 cases[traffic accident 20, fall down 4, others 2] and penetrating trauma in 14 cases[stab wound 13, gun shot 1]. In the blunt trauma, 21 of 26 cases were diagnosed within 24 hours after injury and all cases except one in penetrating trauma were diagnosed within 24 hours. In the blunt trauma, the rupture site was located in the left in 20 cases and in the right in 6 cases. In the penetrating trauma, the rupture site was located in the left in 10 cases and in the right in 4 cases. The repair of 40 cases were performed with thoracic approach in 19 cases, thoracoabdominal approach in 17 cases and abdominal approach in 4 cases. The postoperative mortality was 7.5 %[3/40]. The causes of death were septic shock[1], acute renal failure[1] and hypovolemic shock[1].

  • Anterior tibialis ruptures are a rare type of injury related to the foot and ankle. Specifically, chronic and non-traumatic ruptures are related to preexisting chronic tendinopathic conditions and anatomical factors. These ruptures may cause persistent pain and functional impairments if neglected. Chronic tibialis anterior ruptures are frequently diagnosed late because the symptoms are not distinct. In cases with chronic or non-traumatic tibialis anterior tendon ruptures, tendons often become irreparable. Hence, various surgical options have been introduced to address this issue. The current surgical treatment options are as follows: free sliding anterior tibialis graft, extensor hallucis longus tendon transfer, and reconstruction with an allograft tendon. To date, there have been few reports about the reconstruction technique using Z-plasty for irreparable tibialis anterior tendon ruptures. In this report, we present a rare case of the application of the tibialis anterior tendon reconstruction technique using Z-plasty and tenodesis for a middle-aged man with an irreparable avulsion injury rupture. We also present the management plan and prognostic outlook, as well as a subsequent review of the relevant literature.

  • Rupture of the posterior left ventricular wall following mitral valve replacement is a rare but fatal complication. Over a 10 year period from August 25 1980 to November 27 1990, we have experienced 6 such patients among 884 cases of mitral valve replacement with 4 deaths and 2 survivors. One patient had a type I rupture and another a type II rapture with the remaining four patients having suffered type III ruptures. All of the ruptures were dis covered intraoperatively enabling prompt reinstitution of the cardiopulmonary bypass and subsequent cardioplegic arrest prior to repair. Overzealous removal of calcified valve leaflets seemed to be responsible for the single type I rupture, and untethering of the so called ventricular loop appeared to be the main mechanism responsible for the type III ruptures. The single type II rupture that had occurred seemed to have been caused by inadvertent laceration of the papillary muscle with resultant rupture of the posterior LV wall at the base of the papillary muscle. Among the type III ruptures, 2 patients required intraaortic balloon pump[IABP] support only for mechanical assistance and 1 patient required both the IABP and the Biomedicus LV assist device for successfull weaning following repair of the LV rupture Another patient with a type II rupture also required the circulatory assistance of both the IABP and the bio-medicus LV assist device for weaning from the bypass. Attention to meticulous technical considerations such as avoiding over aggressive removal of heavily calcified valvular tissue, preservation of as much mural leaflet tissue and chordal stuctures as possible seemed helpful in preventing this catastrophic complication from occurring. Fusion and fibrous stricture of the chordal structures appeared particularly conducive to the type II ruptures as a result of the increased susceptibility to papillary injury during operation.

  • Large earthquakes with (MW > ~ 6) result in ground shaking, surface ruptures, and permanent deformation with displacement. The earthquakes would damage important facilities and infrastructure such as large industrial establishments, nuclear power plants, and waste disposal sites. In particular, earthquake ruptures associated with large earthquakes can affect geological and engineered barriers such as deep geological repositories that are used for storing hazardous radioactive wastes. Earthquake-driven faults and surface ruptures exhibit various fault zone structural characteristics such as direction of earthquake propagation and rupture and asymmetric displacement patterns. Therefore, estimating the respect distances and hazardous areas has been challenging. We propose that considering multiple parameters, such as fault types, distribution, scale, activity, linkage patterns, damage zones, and respect distances, enable accurate identification of the sites for deep geological repositories and important facilities. This information would enable earthquake hazard assessment and lower earthquake-resulted hazards in potential earthquake-prone areas.

  • Acute rupture of the tibialis anterior tendon is rare, but the diagnosis is often delayed when it occurs. Acute rupture of the tibialis anterior tendon is often caused by minor trauma or it occurs spontaneously. Therefore, the diagnosis is more likely to be delayed. Among ruptures of the tibialis anterior tendon, longitudinal ruptures are less common and difficult to diagnose. Thus far, there are no reports of ruptures of the tibialis anterior tendon caused by direct trauma in Korea. This paper reports a case of chronic longitudinal tear of the tibialis anterior tendon caused by trauma in a 50-year-old male patient with no specific history of the disease, along with a review of the relevant literature.

  • Purpose: The purpose of this study was to report the surgical outcome of reconstruction of neglected chronic Achilles tendon ruptures with various methods including Achilles tendon allograft. Materials and Methods: Between October 2003 and November 2008, 8 consecutive neglected chronic Achilles tendon ruptures with the defect gap of more than 4 cm underwent surgical reconstruction including V-Y advancement, gastrocnemius fascial turn-down flap, flexor hallucis longus transfer and Achilles tendon allograft. There were 7 males and 1 female who were evaluated at more than 18 months after surgery. At the time of followup, all patients were assessed with regard to postoperative complications, their self-reported level of satisfaction, the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale, 10 repetitive single heel rise, single leg hopping test, and ankle range of motion. Results: The AOFAS score increased from average 71.4 (50-87) to 96.4 (86-100). All patients were able to perform 10-repetitive single heel raise and single leg hopping at the latest follow up. No patient experienced wound complications and deep infection. Six patients were rated as 'excellent' and the other two as 'good'. Conclusion: Neglected chronic Achilles tendon ruptures could be successfully treated with careful selection of the reconstruction method according to the amount of defect gap. With an extensive defect, Achilles tendon allograft can be a good option when the reconstruction is not feasible otherwise.

  • DuraMote is a remote sensing system developed for the "NIST TIP project: next generation SCADA for prevention and mitigation of water system infrastructure disaster". It is designed for supervisory control and data acquisition (SCADA) of ruptures in water pipes. Micro-electro mechanical (MEMS) accelerometers, which record the vibration of the pipe wall, are used detect the ruptures. However, the performance of Duramote cannot be verified directly on a water distribution system because it lacks an acceptable recordable level of ambient vibration. Instead, a long-span cable-stayed bridge is an ideal test-bed to validate the accuracy, the reliability, and the robustness of DuraMote because the bridge has an acceptable level of ambient vibration. The acceleration data recorded on the bridge were used to identify the modal properties of the structure and to verify the performance of DuraMote. During the test period, the bridge was subjected to heavy rain, wind, and a typhoon but the system demonstrates its robustness and durability.
