Abstract
Lateral subtalar dislocations are rare and severe injuries caused by high-energy trauma, and they require urgent treatment. We reported two cases of lateral subtalar dislocation, which were treated with different methods. In case of open lateral subtalar dislocation, we used the method of distractional external fixation; the final outcome was good, without avascular necrosis of the talus. The case of closed subtalar dislocation has been treated with open reduction and K-wires fixation. The final outcome was poor, with avascular necrosis of the talus. Our opinion is that ligamentotaxis of the ankle and subtalar joint with unilateral external fixation unloads the talus and reduces the possibility of the development of avascular necrosis of the talus.

Abstract
Background Distraction arthrodesis (DA) and stabilization of the sacroiliac (SI) joint by placing standalone structural allograft (SA) into the joint from a posterior trajectory has recently been introduced as a surgical procedure for chronic SI joint pain refractory to non-operative care. Methods Retrospective case series of patients with recurrent and/or persistent pain after placement of one or more interpositional/intraarticular standalone SAs between the ilium and sacrum using a posterior procedure to treat SI joint pain/dysfunction. Patients subsequently underwent surgical revision with porous titanium fusion implants using a lateral transfixing procedure. The demographic, clinical, and radiographic features of these cases are described. Results Data were available for 37 patients. The average (SD) age was 57 (13) years, 62% were female, and the average BMI was 31 (5.4). On average, two SA implants were placed per joint; 46% of cases were bilateral. At follow-up, two common themes were identified: lucencies around the implants and suboptimal implant position. None of the cases showed radiographic fusion of the SI joint prior to revision. One patient had an inflammatory reaction to the SA. All patients presented for revision due to either continued (49%) or recurrence (51%) of pain. In one revision case, the SA was forced ventrally, resulting in a sacral fracture, which was treated conservatively without sequelae. Conclusions The popularity of standalone SA for SI joint stabilization/fusion with a posterior procedure is increasing. This case series demonstrates that clinical failures from this procedure may require surgical revision. The proposed fusion strategy (DA) for these products is unproven in the SI joint, and, therefore, properly conducted prospective randomized clinical trials with long-term clinical and radiographic follow-up are important to establish the safety and efficacy of this approach. In the meantime, the placement of lateral titanium implants appears to be an effective revision strategy.

Abstract
OBJECTIVE An advantage of lateral lumbar interbody fusion (LLIF) surgery is the indirect decompression of the neural elements that occurs because of the resulting disc height restoration, spinal realignment, and ligamentotaxis. The degree to which indirect decompression occurs varies; no method exists for effectively predicting which patients will respond. In this study, the authors identify preoperative predictive factors of indirect decompression of the central canal. METHODS The authors performed a retrospective evaluation of prospectively collected consecutive patients at a single institution who were treated with LLIF without direct decompression. Preoperative and postoperative MRI was used to grade central canal stenosis, and 3D volumetric reconstructions were used to measure changes in the central canal area (CCA). Multivariate regression was used to identify predictive variables correlated with radiographic increases in the CCA and clinically successful improvement in visual analog scale (VAS) leg pain scores. RESULTS One hundred seven levels were treated in 73 patients (mean age 68 years). The CCA increased 54% from a mean of 0.96 cm2 to a mean of 1.49 cm2 (p < 0.001). Increases in anterior disc height (74%), posterior disc height (81%), right (25%) and left (22%) foraminal heights, and right (12%) and left (15%) foraminal widths, and reduction of spondylolisthesis (67%) (all p < 0.001) were noted. Multivariate evaluation of predictive variables identified that preoperative spondylolisthesis (p < 0.001), reduced posterior disc height (p = 0.004), and lower body mass index (p = 0.042) were independently associated with radiographic increase in the CCA. Thirty-two patients were treated at a single level and had moderate or severe central stenosis preoperatively. Significant improvements in Oswestry Disability Index and VAS back and leg pain scores were seen in these patients (all p < 0.05). Twenty-five (78%) patients achieved the minimum clinically important difference in VAS leg pain scores, with only 2 (6%) patients requiring direct decompression postoperatively due to persistent symptoms and stenosis. Only increased anterior disc height was predictive of clinical failure to achieve the minimum clinically important difference. CONCLUSIONS LLIF successfully achieves indirect decompression of the CCA, even in patients with substantial central stenosis. Low body mass index, preoperative spondylolisthesis, and disc height collapse appear to be most predictive of successful indirect decompression. Patients with preserved disc height but severe preoperative stenosis are at higher risk of failure to improve clinically.

Abstract
Background and objective Fractures of the proximal interphalangeal joint (PIPJ) of the hand have always been difficult to treat, often leading to less than satisfactory outcomes. The use of dynamic external fixator devices to treat these fractures is well established and it is based on the philosophy of minimal soft tissue injury and early joint mobilization. There has been a wide variety in their designs, surgical technique, and reported outcomes. This study aimed to report the long-term outcome following the use of the Ligamentotaxor® device (Ligamentotaxor1, ArexTM, Palaiseau, France) in treating fractures of the PIPJ of the hand. Methods Between 2009 and 2018, 33 patients treated in our institution with Ligamentotaxor® for fractures of the PIPJ were followed up for a minimum period of 12 months. Radiographs and clinical records were reviewed for clinical and functional outcomes including finger range of motion (ROM), union, Quick Disability of the Arm, Shoulder, and Hand (QuickDASH) score, and any complications. Results A total of 33 patients completed a minimum follow-up of 12 months (mean: 27.5 months). All fractures showed radiological union at a mean of 33 days. Surgery was performed within a mean of 8.9 days and surgical operating time averaged 23.7 minutes. Devices were removed at a mean of 33 days. At the end of the follow-up, the mean range of flexion was 66 degrees and the mean extension lag was six degrees. The mean QuickDASH score was 8.72. Of note, 85% of the patients experienced no limitations in their daily activities, while 35% reported pain on exertion. One patient had a pin tract infection. Four patients had cold intolerance and persistent swelling. Conclusion The results of the use of Ligamentotaxor® in this series are comparable to those of other dynamic external fixator devices reported in the literature. Thanks to its quick and easy surgical technique, the device provides an appealing option for the management of PIPJ fractures.

Abstract
BACKGROUND The objective of this study is to determine the time-dependent dissipation of extrinsic wrist ligament tension following the application external fixation with axial distraction of the wrist in a cadaveric model. METHODS Six paired fresh-frozen cadaveric specimens underwent mechanical testing simulating external fixation with 1 arm of each pair osteotomized to simulate a distal radius fracture. The change in tension was then recorded over 24 hours. RESULTS The rate of stress relaxation decreased with time. The average loss in tension in the control arms and osteotomized arms was 55% and 59%, respectively, over a 24-hour period. There was no statistically significant difference in the stress relaxation behavior between the 2 groups. CONCLUSION This study further supports the recommendation that comminuted distal radius fractures treated with an external fixator should have Kirschner wire augmentation or other additional means of fixation to help maintain fracture length and alignment. The results of this study call in to question the efficacy of ligamentotaxis alone through external fixation as the sole means of maintaining reduction of displaced, unstable distal radius fractures.

Abstract
UNLABELLED Background The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations (PLDs) and fracture-dislocations (PLFDs) treated with external fixation and Kirschner wires (K-wires). Materials and Methods Twenty patients (18 males and 2 females) with a mean age of 38 years (range 18-59) with an acute PLD or PLFD were treated with external fixator and K-wires. There were 12 PLDs and seven transscaphoid and one transstyloid PLFDs. The median time from trauma to operation was 8 hours (range 2-12 hours). Indirect reduction via ligamentotaxis was achieved in 17 patients with a mean age of 38years (range 18-59). There were 12 PLDs and 5 trans-scaphoid PLFDs; however, in three cases (two transscaphoid and one transstyloid PLFDs), indirect reduction failed and an open reduction was required. The intercarpal ligaments were not repaired even after open reduction. Results The mean follow-up was 39 months (range 18-68 months). The flexion-extension range of motion (ROM) and grip strength of the injured wrist averaged 80% and 88%, respectively, of the corresponding values for the contralateral wrists. According to Cooney's scoring system, overall functional outcomes of the 17 patients were rated as excellent in 4 patients, good in 8, fair in 4, and poor in 1. Fifteen patients returned to their former occupations. Two patients with a trans-scaphoid perilunate injury developed nonunion of the scaphoid, and two developed posttraumatic arthritis. Conclusion External fixation plus percutaneous K-wires for the treatment of acute PLDs has satisfactory midterm functional and radiographic outcomes. When successful, this minimally invasive technique is simple and provides restoration of the carpal alignment. It may especially be useful in the polytrauma patient, thanks to its decreased operative time and diminished blood loss, when other emergent surgical procedures may be necessary. An open reduction with possible fixation may be necessary for PLDs and PLFDs, especially in the presence of polytrauma and scaphoid comminution. LEVEL OF EVIDENCE IV.

Abstract
We present the outcomes of the delayed management of eight displaced intra-articular fractures of the metacarpal and phalangeal heads treated with capsuloligamentotaxis using the Penning mini-external fixator. Closed anatomical reduction with a 2 mm over-distraction was achieved at the time of operation at an average of 20 days after the initial injury. Excellent outcomes in terms of function and pain were obtained at 6 month's follow-up in all cases. This technique is simple, minimally invasive, and effective, with minimal complications.

Abstract
Transstyloid, transscaphoid, transtriquetral perilunate dislocations are extremely rare carpal dislocations. We report a 24-year-old male who presented with this rare injury pattern four weeks after sustaining trauma. The patient underwent open reduction and internal fixation via dorsal approach. Reduction was assisted by the use of Joshi's Distraction System. Scaphoid fracture healed by 16 weeks. At 2 years follow-up patient has good range of motion around wrist without any discomfort.

Abstract
BACKGROUND Controversies exist in the literature regarding the management of complex fractures of the calcaneum. We evaluated a series of complex fractures of the calcaneum managed by ligamentotaxis using Joshi's external stabilization system (JESS) for its efficacy. MATERIALS AND METHODS Forty-five patients having complex (comminuted, intra-articular fracture with compromised soft tissue condition) fractures of the calcaneum, who were treated by external fixator (JESS) based on the principle of ligamentotaxis. The gradual distraction was done to bring the articular margins together to maintain both alpha and beta angles to near normal range. Thirteen (28.9%) patients underwent additional corticocancellous bone grafting with elevation of posterior facet. All patients were evaluated for their functional outcomes by American Orthopedic Foot and Ankle society (AOFAS) Score for the ankle and hind foot. Mean duration of follow-up was 20.5 months. RESULTS Forty-two (93.4%) of our patients did well with the ligamentotaxis. On evaluating final outcomes by AOFAS, approximately 71% of cases showed good results. Eleven patients (24.4%) complained of persistent heel pain in the long-term follow-up. Out of these, eight (17.8%) patients were those who had severe comminution with almost total loss of calcaneal height. The origin of heel pain was not the subtalar joint in all of these patients. On long-term follow-up none of these patients suffered from such severe pain so as to compel them to change the nature of their activity. CONCLUSION We conclude that ligamentotaxis by JESS provides a viable and user-friendly alternative method of management of these complex calcaneal fractures.
