Although calcaneal fracture is relatively common in ankle injury, open intraarticular calcaneal fracture with dorsal dislocation of the navicular from talus is extremely rare and severe injury. There are few data which are available concerning the injury mechanism and treatment options. The purpose of this report is to describe a case with bilateral open transcalcaneal fracture with talonavicular dislocation and to discuss the prevalence, mechanism of this injury, and treatment options.

Open reduction and internal fixation is currently considered as a gold standard of treatment in most of the intra-articular calcaneal fractures. Among various different approaches, extensile lateral approach is the most popular since it provides good exposure to the subtalar joint. However, wide skin incision followed by extensive soft tissue dissection leading to increased risk of wound breakdown is the most serious drawback. Sinus tarsi approach, a minimal invasive technique to approach the subtalar joint and reduce the intra-articular calcaneal fractures, provides good clinical outcome and less wound complications compared to the extensile lateral approach. This article introduces the surgical technique and review of the literature regarding the sinus tarsi approach.

Secondary soft tissue injuries can occur from the pressure of the displaced fragment of posterior calcaneal tuberosity in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The soft tissue injury can be prevented by immediate reduction of the displaced fragments. Various techniques can be used to fix the fracture fragments, but the stability of fixation and minimal invasiveness to soft tissue should be considered. This paper reports the successful outcomes of patients with soft tissue compromises in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The fixation technique of a large cannulated screw and simple cerclage wiring is believed to be a useful surgical option for the treatment of secondary soft tissue compromised calcaneal fractures.

Ankle sprains are among the most common injuries sustained during athletic activities and daily life. Acute ankle sprain is usually managed conservatively with functional rehabilitation but the failure of conservative treatment leads to the development of chronic ankle instability. The development of repetitive ankle sprains and persistent symptoms after injury has been termed chronic ankle instability. Acute ankle sprains and chronic ankle instability require a careful evaluation to detect other comorbidities, such as subtalar instability, osteochondral defect, peroneal tendinopathy, tarsal coalition, os trigonum, flexor hallucis longus tendinitis, calcaneus anterior process fracture, and neural injuries. For the successful treatment of acute ankle sprains and chronic ankle instability, the treatment of comorbidity lesions should be performed first.

OBJECTIVE: To compare the clinical efficacy of staged surgery on Sanders Ⅳ calcaneal fractures with soft tissue Ⅲ swelling. METHODS: The clinical data of 76 patients with Sanders type Ⅳ closed calcaneal fracture with soft tissue three-degree swelling treated from June 2017 to May 2020 was retrospectively analyzed, including 54 males and 22 females, aged from 25 to 50 (38.16±10.24) years. The patients were divided into observation group and control group according to different treatment methods. Twenty-four patients in the observation group were treated by staged surgery stageⅠclosed prying traction reduction and Kirschner wire fixation, stageⅡopen reduction and internal fixation with titanium plate, including 17 males and 7 females, aged from 25 to 50 (36.12±9.56) years. There were 52 patients in the control group, including 37 males and 15 females, aged from 25 to 50 (38.32±10.67) years, these patients were treated with open reduction and internal fixation with titanium plate after the dermatoglyphic signs appeared. The swelling subsidence time, the length of hospitalization days, and the incidence of postoperative incision complications were compared between two groups. The Bhler angle, Gissane angle, and calcaneal varus angle were measured by X-ray before and 6 months after operation. American Orthopedic Foot and Ankle Society (AOFAS) about the ankle hindfoot score was used to evaluate the clinical efficacy. RESULTS: All 76 patients were followed up for 8 to 12 (9.52±2.01) months. The swelling subsidence time and hospitalization days in observation group were (12.12± 3.24) d and (24.53±6.44) d, respectively, which in control group were (15.16±4.16) d and (29.46±9.61) d, with statistical difference between two groups ( CONCLUSION Compared with open reduction and internal fixation with titanium plate after the appearance of dermatoglyphic signs, staged surgery for Sanders type Ⅳ calcaneal fractures with soft tissue three-swelling does not increase the risk of soft tissue complications, and can significantly shorten the patient's swelling subsidence time and hospitalization days, improve the quality of fracture reduction and short term function, and relieve pain.

PURPOSE: A barbed suture used in flexor tenorrhaphy can maintain prolonged strength despite absorption of the suture material and allows knotless repair with tendon-barb adherence along the suture's entire length. The purpose of this study was to evaluate the strength of the tendon and its histologic analysis after tenorrhaphy using barbed sutures. METHODS: Forty-two New Zealand rabbits were used in this study and were divided into experimental and control groups. In the experimental group, knotless repair of the tendons was performed using absorbable barbed sutures. In the control group, a 4-stranded double-modified Kessler tenorrhaphy was performed using non-absorbable monofilament sutures. The force to failure for each tendon was measured immediately after tendon repair and at 1 week, 4 weeks, and 8 weeks after the repair. Microscopic analysis of the tendons was performed at 1 week, 4 weeks, and 8 weeks after their repair. RESULTS: Eight weeks after tendon repair, the force to failure value of the rabbits in the experimental group (144.02+/-10.21 N) was significantly higher than that of the rabbits in the control group (125.26+/-8.75 N) (p=0.032). The difference in the value during the periods was not statistically significant. Histologic findings showed increased foreign body reaction in the tendons of the experimental group and sustained inflammation in those of the control group. CONCLUSION: With respect to load to failure and the degree of inflammation, the use of absorbable barbed suture resulted in better tendon repair than the conventional non-absorbable suture.
