Objective: To investigate the safety and efficacy of piezosurgery in anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy (CSM).

Methods: 47 patients with complex CSM (cCSM) underwent ACDF surgery from 2014 to 2017. Among these patients, 26 underwent ACDF using piezosurgery (group A) and 21 underwent ACDF by using traditional tools such as high-speed air drill, bone curette, and Kerrison bone punch (group B). Average surgical time, intraoperative blood loss, surgical complications, preoperative and postoperative Japanese Orthopaedic Association (JOA) scores, and improvement rate were measured.

Results: Average surgical time and intraoperative blood loss were significantly lower in group A than those in group B (P < 0.01). The incidences of surgical complications were 3.8% and 23.8% in the A and B groups (P < 0.05), respectively. There were no significant differences in JOA scores and improvement rates between data collection periods at preoperative, 3-day postoperative, and 1-year postoperative follow-ups (P > 0.05).

Conclusion: For treating cCSM, both the piezosurgery and traditional tools led to significant neurological improvement. However, the piezosurgery was superior to the traditional tools in terms of surgical time, blood loss, and complication rate. Hence, piezosurgery was a safe and effective adjunct for ACDF treating cCSM.

Background: Nondiabetic patients with open leg fractures who have elevated blood glucose levels on arrival in the emergency department have an increased risk of surgical-site infections (SSIs).

Objective: This study evaluates the association between the incidence of SSIs in nondiabetic patients with an open leg fracture and blood glucose levels registered on arrival in the ER. We also analyzed the correlation between patients' days of hospital stay and the incidence of SSIs and the time elapsed between the damage control with external fixation and final fixation and the incidence of SSI.

Methods: We retrospectively studied nondiabetic patients admitted to our emergency unit from 2017 to 2021 with a diagnosis of open leg fracture consecutively treated. Based on the diagnosis of SSIs, all enrolled patients were divided into two groups based on the developed (group A) or not developed (group B) SSIs within 1 year after surgery. All patients enrolled in the study underwent damage control within 24 hours after admission to the ER. At stabilization of general clinical and local wound conditions, all patients underwent definitive surgery.

Results: We enrolled 80 patients. In group A, glycemia on arrival in the ER was on average 148.35 ± 19.59 mg/dl, and in group B, it was 122.61 ± 22.22 mg/dl (p value: 0.0001). In group A, glycemia in the first postoperative day was on average 113.81 ± 21.07 mg/dl, and in group B, it was 99.02 ± 17.60 mg/dl (p value: 0.001). In group A, the average hospitalization was 57.92 ± 42.43 days, and in group B, it was 18.41 ± 14.21 days (p value: 0.01). Through Youden's J, we therefore analyzed the value with the highest sensitivity and specificity which proved to be 132 mg/dl.

Conclusion: Our findings show that nondiabetic patients with SIH have a significantly increased risk of SSIs compared to patients without SIH within 1 year after surgery. Patients with open leg fractures with SIH have a significantly higher average hospital stay than patients without SIH. Further studies are needed to confirm 132 mg/dl of blood glucose levels as a value to stratify the risk of SSIs in these patients.

Objective: This study aims to evaluate the outcomes of single intramedullary K-wire fixation in nonthumb, metacarpal shaft fractures with immediate postoperative hand mobilization without any immobilization.

Method: This is a retrospective case series conducted from January 2019 to December 2022. We included patients with closed, simple transverse, or short oblique metacarpal shaft fracture treated with single, 1.4 mm, intramedullary K-wire fixation. Gentle postoperative range of motion exercise was encouraged in every patient without any hand, finger, or wrist motion restriction material. Clinical outcomes were evaluated with total active flexion; grip strength; disability of arm, shoulder, and hand (DASH) score; and the American Society for Surgery of the Hand Total Active Flexion (ASSH TAF) score.

Results: This study included 34 patients, 25 males and 9 females with a mean age of 33.14 years (ranging 18-59). A total of 43 metacarpal shafts were treated. The mean DASH score at two and 6 weeks postoperative was 41.5 (ranging 19.16-60.34) and 9.58 (ranging 0.83-23.27). The mean final DASH score at last follow-up was 3.48 (ranging 0-8.33). Mean TAF at 2 weeks postoperative, 6 weeks postoperative, and at final follow-up was 203.8 (ranging 185-240), 238.2 (ranging 220-270), and 259.25 (ranging 240-270) degrees, respectively. The mean grip strength of the injured hand was 66.14 and 86.1% of the uninjured hand at 6 weeks and 3 months postoperative. There was no nonunion, malrotation, or infection. In conclusion, single intramedullary K-wire fixation gives excellent outcomes in the treatment of single or multiple, simple, metacarpal shaft fractures without the need of postoperative immobilization.

Objectives: Tibial shaft fractures are treated with both intramedullary nailing (IMN) and plate fixation (ORIF). Using a large national database, we aimed to explore the differences in thirty-day complication rates between IMN and ORIF.

Methods: Patients in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database who had undergone either tibial IMN or ORIF for closed fractures from 2010 to 2018 were identified using current procedural terminology (CPT) codes. After excluding all patients with open fractures, the propensity score was matching. Univariate and multivariate logistic regressions were used to identify risk factors associated with the thirty-day incidence of complications in the two cohorts.

Results: A total of 5,400 patients were identified with 3,902 (72.3%) undergoing IMN and 1,498 (27.7%) ORIF. After excluding any ICD-10 diagnosis codes not pertaining to closed, traumatic tibial shaft fractures, 2,136 IMN and 621 ORIF cases remained. After matching, the baseline demographics were not significantly different between the cohorts. Following matching, the rate of any adverse event (aae) did not differ significantly between the IMN (7.08% (n = 44)) and ORIF (8.86% (n = 55)) cohorts (p=0.13). There was also no significant difference in operative time (IMN = 98.5 min, ORIF = 100 min; p=0.3) or length of stay (IMN = 3.7 days, ORIF = 3.3 days; p=0.08) between the cohorts.

Conclusion: There were no significant differences in short-term complications between cohorts. These are important data for the surgeon when considering surgical management of closed tibial shaft fractures.

Purpose: Periarticular infiltration (PI) is a common procedure during total knee arthroplasty (TKA) for postoperative pain management. This retrospective, case-matched study aimed to evaluate the effectiveness of PI with dexamethasone and bupivacaine in combination with an adductor canal block (ACB) and compare it with that of ACB alone in reducing postoperative pain in patients with TKA.

Methods: Data were collected from 66 patients who underwent TKA performed by a single surgeon. Thirty-three of them received ACB + PI, and 33 received ACB alone. However, both groups underwent identical surgical techniques and postoperative care protocols. The pain scores and fentanyl consumption of the two groups were compared.

Results: The ACB + PI group had significantly lower pain scores than the ACB alone group at 8, 16, 24, and 48 hours postoperatively (p=0.033, 0.004, 0.038, and 0.049, respectively). The percentage of patients requiring fentanyl as a rescue medication was significantly higher for the ACB alone group (90.9%) than for the ACB + PI group (69.7%, p=0.03). The total fentanyl consumption was also lower for the ACB + PI group (p < 0.001).

Conclusion: The periarticular injection of the combination of dexamethasone and bupivacaine plus ACB was more effective than ACB alone in reducing postoperative pain and fentanyl consumption in patients undergoing TKA. Further studies comparing different doses of dexamethasone or other cocktail regimens may provide additional insights into this approach.

Background: Pes anserine bursitis (PAB) is one of the most common causes of painful knee syndromes. This study aimed at examining the efficacy of local corticosteroid injection, platelet-rich plasma (PRP) injection, and extracorporeal shock wave therapy (ESWT) as different modalities to alleviate pain and enhance function in patients with pes anserine bursitis (PAB).

Methods: A prospective, randomized, comparative study was conducted on 180 patients diagnosed with chronic PAB. They were equally divided into three groups as follows: Group I received a local corticosteroid injection of 40 mg of methylprednisolone acetate/1 ml; Group II received a PRP injection; and in Group III, ESWT was used. Outcome measures included the visual analog scale (VAS), Western Ontario and McMaster Universities (WOMAC) pain score, WOMAC physical function score, and Ritchie articular index (RAI) for tenderness, which were recorded at the baseline, after 1 week, and after 8 weeks.

Results: Before the application of procedures, there was a statistically significant increase in the WOMAC pain score in the local corticosteroid group compared to the PRP group and the ESWT group (P < 0.001). After the application of procedures, there was a statistically significant improvement in the 1-week and 8-week WOMAC pain score, WOMAC physical function score, and VAS in the local corticosteroid group in comparison to the PRP group and the ESWT group. (P < 0.001). Moreover, RAI for tenderness shows statistically significant improvement at 8 weeks in the local corticosteroid groups compared to the PRP groups (P < 0.001) and ESWT groups (P < 0.001). Similarly, a statistically significant difference was found between the PRP and ESWT groups (P=0.023).

Conclusion: Our data suggest that in patients with PAB, local corticosteroid injection is more efficient than PRP injection and ESWT for reducing pain and enhancing function.
