ABSTRACT
Objective:To investigate the efficacy of TiRobot navigation combined with ankle arthroscopy in the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture.Methods:From January 2019 to September 2020, a total of 13 patients with Hawkins type Ⅱ talus neck fracture were admitted to Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. They were 8 males and 5 females, with a mean age of 35.8 years (from 22 to 61 years). All fractures were reduced and fixated using TiRobot navigation combined with ankle arthroscopy. Time for fracture reduction assisted by intraoperative arthroscopy, time for internal fixation assisted by TiRobotic navigation, fracture union time and complications were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used at the last follow-up to evaluate the functional outcomes.Results:All the operations were finished within 2 hour. The primary screw placement succeeded in all. The time for fracture reduction assisted by intraoperative arthroscopy averaged 52.8 min (from 43 to 66 min) and the time for internal fixation assisted by TiRobotic navigation 43.6 min (from 33 to 55 min). All the patients were followed up for an average 13.3 months(from 12 to 15 monhs). They obtained bony union within 3 months. One patient developed traumatic subtalar arthritis with mild pain and was treated conservatively. None of the patients had complications like incision infection or talus necrosis. The average AOFAS ankle-hindfoot score was 91.0 points (from 83 to 94 points) at the last follow-up.Conclusion:In the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture, TiRobot navigation combined with ankle arthroscopy shows advantages of minimal invasion, accurate reduction and screw placement, and limited complications, leading to fine short-term functional outcomes.
ABSTRACT
Objective:To summarise the experience in use of sural neurouascular flap in repair of the soft tissue defects of foot and ankle, and explore the methods in promoting the survival and appearance of the flap.Methods:Data of 10 patients who underwent sural neurocutaneous flap surgery for repairing soft tissue defects in the foot and ankle in the Department of Foot and Ankle of Xuzhou Renci Hospital from October 2019 to June 2020 were retrospectively analysed. Among the 10 patients, 8 were males and 2 were females, and the age ranged from 18 to 54 years old, with an average age of 42.5 years old; Causes of injury: 8 patients injured by traffic accident and 2 by incision necrosis after calcaneal fracture operation. The areas of soft tissue defect were 4.0 cm×6.0 cm-16.0 cm×10.0 cm. Sural neurouascular flap was used for the defect repairs. Method of optimisation: ①The small saphenous vein in the flap was separated and retained in the limb to optimise the venous circulation. ②Freed peroneal perforator vessels that entered the pedicle, and made the point where the vessels entering the pedicle as the rotation point. The pedicle contained the sural neurovascular bundle, the main trunk of the small saphenous vein and the fascia tissue, with a width about 2.0 cm. It not only increased the blood supply of the flaps, but also a good appearance of the pedicle. ③ The torsion of the pedicle was covered by an arc-shaped flap and transferred through an open channel to prevent compression. ④The donor site was covered with relay flap. According to the location of the donor site, a proximal peroneal artery perforator flap or medial and lateral sural artery perforator flap was selected. ⑤Sural nerve was anastomosed with the peripheral sensory nerve in some cases. The survival of the flap, Maryland Foot Function Score and British Medical Research Council (BMRC) sensory function evaluation were investigated in the follow-up to evaluate the functional recovery of the flap and limb.Results:All the 10 patients received the follow-up for 6 to 12 months, with an average of 8.5 months. The donor and recipient flaps survived completely with good appearance in lower limb, good soft texture, good elasticity and wear resistance. The sensation of the flap with nerve anastomosis in 3 cases was evaluated according to BMRC, and they achieved sensation recovery up to level of S 3 or above. The patients had great satisfactions. At the last follow-up, the curative efficacy was evaluated according to the Maryland scoring system. It ranged from 85 to 98 points, with an average of 91.6 point, 8 patients in excellent and 2 in good. Conclusion:Sural neurouascular flap can achieve a sufficient blood supply, a reasonable venous circulation and a high survival rate. The donor site was covered with relay flap to obtain a good appearance, and the anastomosed sensory nerve offered a good sensation. The function of foot and ankle recovered well, and the clinical effect was satisfactory.
ABSTRACT
Objective:To investigate the clinical efficacy of a new 3D printed guide plate in the minimally invasive treatment of fresh closed Achilles tendon rupture.Methods:From January 2019 to January 2020, 14 fresh closed Achilles tendon ruptures were treated by minimally invasive surgery at Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. There were 13 males and one female, with an average age of 39.1 years (from 18 to 63 years). The rupture of the Achilles tendon body, 3 cm in length on average, was located 2 to 6 cm above the attachment of the calcaneal tuberosity. The ruptured Achilles tendon was repaired by suture with the aid of the new 3D printed guide plate. After operation, in cooperation of the Rehabilitation Department, we performed rehabilitation exercise under the guidance of the concept of Enhanced Recovery After Surgery (ERAS). The length of incision, operation time, intraoperative blood loss, ankle function at the last follow-up and follow-up complications were recorded.Results:In this cohort, incision length averaged 2.5 cm (from 2.0 to 3.5 cm), operation time 45 min (from 30 to 60 min), and intraoperative blood loss 15 mL (from 10 to 20 mL). The 14 patients were followed up for 13 to 16 months (average, 14 months) after operation. In one patient, the epidermis at the incision edge became black and necrotic, which was healed after dressing change. Follow-ups observed no such complications as suture rejection, sural nerve injury, or Achilles tendon re-rupture. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores at the last follow-up averaged 98 points (from 93 to 99 points), yielding 13 excellent cases and one good case; according to the Arner-Lindholm evaluation, the efficacy was excellent in 12 cases, good in one and poor in one.Conclusion:The minimally invasive treatment of fresh closed Achilles tendon rupture with our new 3D printed guide plate has exhibited advantages of minimally invasive incision, limited complications, simple manipulation, good functional recovery of the ankle joint and strong reproducibility of surgical operations.
