Treatment of Lisfranc Fracture Dislocations with an Interosseous Suture Button Technique: A Review of 3 Cases

Lisfranc fracture dislocations are complex and difficult to treat. Making the correct diagnosis and achieving an anatomical reduction are important factors in regard to achieving a favorable outcome with this injury. We describe a new technique that we have found to be useful for stabilizing Lisfranc fracture dislocations. This method is relatively fast, minimally invasive, and effective, and it eliminates the need for implant removal. To date, we have achieved predictable results for stabilizing and treating these difficult injuries with the use of a suture endobutton, instead of traditional interfragmental screw fixation. In this report, we describe 3 cases in which this method was used with satisfactory short-term results. LEVEL OF CLINICAL EVIDENCE: 4.     

Acute Proximal Row Carpectomy after Complex Carpal Fracture Dislocation

Acute proximal row carpectomy is an uncommon definitive treatment for perilunate fracture dislocations. In this report, we present five patients who had acute proximal row carpectomy (PRC) to treat perilunate fracture-dislocations. All patients were men between ages 31 and 87. The indication for PRC was lunate fracture in two patients, concomitant displaced scaphoid fracture and scapholunate ligament injury in two patients, and perilunate fracture-dislocation with preexisting articular damage from long-standing gout in one patient. At the final follow-up ranged from 4.5 month to 7.5 years, four patients had no pain and one patient was lost to follow-up. One patient had a concomitant PRC and a bridging plate that was never removed. The remaining three patients gained satisfactory range of motion. Our observation reveals that acute proximal row carpectomy is an option for some patients with complex carpal fracture dislocations, particularly those with fracture of the lunate, concomitant scaphoid fracture and scapholunate ligament injury, or preexisting wrist arthritis.     

Treatment of an unusual trans-scaphoid perilunate avulsion fracture dislocation: a case report

We describe an unusual case of trans-scaphoid perilunate injury where the proximal half of the scaphoid avulsed from all attaching ligaments and extruded into the forearm. Treatment involved anatomic reduction and internal fixation of the fracture, scapholunate (SL) ligament repair, temporary K-wire fixation, and prolonged immobilization. At 19-month follow-up, the fracture healed, SL ligament remained intact, and the patient recovered much of his hand function.     

加压骑缝钉克氏针治疗经舟骨月骨周围骨折脱位

目的探讨加压骑缝钉克氏针内固定治疗经舟骨月骨周围骨折脱位的临床疗效。方法2006年2月至2008年9月,我们采用加压骑缝钉克氏针内固定治疗11例经舟骨月骨周围骨折脱位患者,年龄18～39岁。术中采用克氏针固定月骨、头状骨,单夹骑缝钉固定舟骨,加压矫正分离移位,术中同时修复关节囊和韧带。术后8周拔除克氏针开始活动,6～12个月根据舟骨愈合情况取出骑缝钉,术后随访6～24个月。结果术后通过腕关节活动度、手握力、用力后腕关节疼痛程度、X线片和CT检查评价治疗效果,患者术后腕关节活动及手握力良好。影像学检查舟骨骨折均骨性愈合,骨折愈合时间4-10月。结论加压骑缝钉克氏针内固定治疗经舟骨月骨周围骨折脱位,直视切口手术,操作简便可靠,可同时修复韧带,并可减少术后并发症,是目前较好的治疗手段之一。     

月骨周围脱位的X线分析

月骨周围脱位多发生于活跃的青壮年男性,是一种严重的腕部损伤,主要依靠腕关节X线检查和临床查体诊断。由于腕关节结构复杂,临床易误诊、漏诊,若诊断或治疗不当,极易引起骨缺血坏死、腕不稳及创伤性关节炎等严重并发症,     

Greater Arch Injuries

Dislocations and fracture dislocations of carpal bones are uncommon injuries which invariably poses challenges in the management. Perilunate fracture dislocations are the combination of ligamentous and osseous injury that involve the “greater arc” of the perilunate associated instability. Despite their severity, these injuries often go unrecognized in the emergency department leading to delayed diagnosis and treatment. A Prospective study was done from June 2008 to December 2013 in 15 cases of complex wrist injuries which included of greater arch injuries, perilunate fracture dislocation and one dorsal dislocation of Scaphoid. 10 cases of perilunate fracture dislocation underwent open reduction and internal fixation with Herbert screw and k-wire, 4 cases of greater arch injury underwent closed reduction and kwire fixation and one case of neglected dorsal dislocation underwent proximal row carpectomy. One patient had Sudecks osteodystrophy 1 had Scaphoid nonunion and 6 had median nerve compression. Overall outcome according to Mayo wrist score was 53 % excellent, 33 % good and 14 % fair. Greater arch injuries are difficult to treat because injuries to many ligaments are involved and failure to recognize early leads to persistent pain, disability and early onset of arthritis. Prompt recognition requires CT scan and MRI. Management requires reduction and multiple K-Wiring according to merits of the case.
