The wide-awake local anesthesia no tourniquet (WALANT) technique is applied during various hand surgeries. We investigated the perioperative variables and clinical outcomes of open reduction and internal fixation (ORIF) for distal radius fractures under WALANT. From January 2015 to January 2017, 60 patients with distal radius fractures were treated, and 24 patients (40% of all) were treated with either a volar or a dorsal plate via WALANT procedure. Of these 24 patients, 21 radius fractures were fixed with a volar plate, and the other 3 were fixed with a dorsal plate. Radiographs; range of motions; visual analog scale (VAS); quick disabilities of the arm, shoulder, and hand (Quick DASH) questionnaire; and time to union were evaluated. One of the 24 patients could not tolerate the WALANT procedure and was reported as a failed attempt at WALANT. In the cohort, 23 patients successfully received distal radius ORIF under WALANT procedure. The average age is 60.9 (range, 20–88) years. The average operation time was 64.3 (range, 45–85) minutes, the average blood loss was 18.9 (range, 5–30) ml, and the average of duration of hospitalization is 1.8 (range, 1–6) days. The average postoperative day one VAS was 1.6 (range, 1–3). The average time of union was 20.7 (range, 15–32) weeks. The mean follow-up period was 15.1 (range, 12–24) months. Functional 1-year postoperative outcomes revealed an average Quick DASH score of 7.60 (range, 4.5–13.6) and an average wrist flexion and extension of 69.6° (range, 55–80°) and 57.4° (range, 45–70°). There was no wound infection, neurovascular injury, or other major complication noted. WALANT for distal radius fracture ORIF is a method to control blood loss by the effects of local anesthesia mixed with hemostatic agents. Without a tourniquet, the procedure prevents discomfort caused by tourniquet pain. Without sedation, patients could perform the active range of motion of the injured wrist to check if there is impingement of implants. It eliminates the need of numerous preoperative examinations, postoperative anesthesia recovery room care, and side effects of the sedation. However, patients who are not amenable to the awake procedure are contraindications.

The anterior iliac crest (AIC) and proximal tibia (PT) are common donor sites for autologous bone graft harvesting. We compared pain levels at these harvest sites on 1 day, 5 days, 2 weeks, 4 weeks, and 8 weeks post-harvest. We retrospectively reviewed 18 patients undergoing autologous bone grafting surgery at a level I trauma center between June 2013 and October 2014. Ten grafts were harvested from the AIC group and eight from the PT group. A standard visual analog scale (VAS) was used to rate pain at the harvest sites on postoperative day (POD) 1, 5, 14, 28, and 56 and at the recipient site on POD 1. There were no statistically significant differences between both groups in age (p = 0.474), gender (p = 1.00), incidence of harvest site morbidity (p = 1.00), and average VAS at the recipient site on POD 1 (p = 0.471). VAS at the harvest site on POD 1, 5, and 14 confirmed statistically that pain was more severe in the AIC group than in the PT group (p < 0.001). However, no significant difference was observed on POD 28 and 56 between both groups. Pain was significantly less on POD 1 in the PT group at the harvest site than at the recipient site (p < 0.001). The PT is a suitable harvest site, producing statistically less pain for at least two postoperative weeks than the AIC. Besides, patients report less postoperative pain at the PT harvest site than at the recipient site.

The purpose of this study was to compare the parameters of perioperative course and cost-effectiveness for patients with midshaft clavicle fractures treated by dynamic compression plates or locked compression plates. This retrospective, case-controlled study involved 54 patients with midshaft clavicle fractures who received dynamic compression plates (n=21) or locked compression plates (n=33) between January 2002 and December 2008. Indications for surgery included displacement or shortening >2 cm, comminuted fractures, and skin tenting. Patients with previous malunion, nonunion, multiple injuries of the shoulder girdle, or open fractures were excluded. Preoperative demographics showed no statistically significant differences between the 2 groups. Eighteen patients with dynamic compression plates and 28 patients with locked compression plates with postoperative follow-up >1 year were included for comparison. Statistical analyses for operative time, blood loss, complication rate, hospital stay, and union rate demonstrated no statistically significant difference between the 2 groups. The only statistically significant difference was a higher rate of plate removal requests in the dynamic compression plate group. Considering medical expenditure, locked compression plates cost 6 times more than dynamic compression plates in the authors’ institution (US $600 vs $100, respectively). Other than more plate removal requests in the dynamic compression plate group and greater expense in the locked compression plate group, dynamic compression plates and locked compression plates achieved satisfactory operative outcomes in treating midshaft clavicle fractures, with no statistically significant difference between perioperative course and eventual fracture union observed between the 2 groups.

Management of pediatric septic coxarthritis and osteomyelitis of the femur is challenging, and the sequelae of multiplanar hip joint deformity with instability are difficult to reconstruct. The inadequacy of a suitable device for fixing small bones during pediatric osteotomy is a hindrance to the correction of subluxated hip joints and deformed femurs in children. Two-dimensional axial images and three-dimensional (3D) virtual models representing the patient’s individual anatomy are usually reserved for more complex cases of limb deformity. 3D printing technology can be used for preoperative planning of complex pediatric orthopedic surgery. However, there is a paucity of literature reports regarding the application of 3D-printed bone models for pediatric post-osteomyelitis deformity. We herein present a case of a 4-year-old boy who underwent treatment for post-osteomyelitis deformity. We performed corrective surgery with Pemberton osteotomy of the right hip, multilevel varus derotation osteotomy of the right femur, and immobilization with a hip spica cast. A 3D-printed bone model of this patient was used to simulate the surgery, determine the proper osteotomy sites, and choose the appropriate implant for the osteotomized bone. A satisfactory clinical outcome was achieved.
