Dorsal plating versus volar plating with limited dorsal open reduction in the management of AO type C3 distal radius fractures with impacted articular fragments: A retrospective comparative study.

OBJECTIVE: The aim of this study was to compare the outcomes of dorsal plating versus volar plating with limited dorsal open reduction in the management of AO type C3 distal radius fractures with impacted articular fragments. METHODS: Thirty patients who underwent dorsal plating (Group A) (14 females, 16 males; mean age = 56.8 ± 10.1 years) and 28 who underwent volar plating with limited dorsal open reduction (Group B) (12 females, 16 males; mean age = 55.6 ± 17.7 years) for type C3 distal radius fractures with impacted articular fragments between 2006 and 2019 were retrospectively analyzed. The mean follow-up was 14.5 ± 3.2 months in group A and 13.2 ± 2.4 months in group B. The articular step-off, articular gap and joint penetration by screws on the computed tomography scans were used for radiologic evaluation. The functional outcomes were evaluated with range of motion, grip power, Quick Disabilities of the Arm, Shoulder, and Hand (DASH) score, and Mayo wrist score. RESULTS: No significant difference was found in the step-off distance at 1 year after surgery between the two groups (P < 0.05). The ranges of extension, rotation, and radial and ulnar deviations did not differ between the groups. However, group B had a significantly higher range of flexion in the wrist joint than Group A (P = 0.010). The grip power, DASH score, and Mayo wrist score did not also differ between the groups. Implant removal owing to any discomfort at the operative site was performed in 15 patients (63%) in Group A and 7 patients (28%) in Group B. CONCLUSION: Similar clinical results can be obtained by both dorsal plating and volar plating with limited dorsal open reduction in treating type C3 distal radius fractures with impacted articular fragments. However, volar plating with limited dorsal open reduction can provide better wrist flexion with a low incidence of complications associated with implantation. LEVEL OF EVIDENCE: Level III, Therapeutic Study.

Clinical Outcomes of Arthroscopic Notchplasty and Partial Resection for Mucoid Degeneration of the Anterior Cruciate Ligament.

BACKGROUND: Mucoid degeneration of the anterior cruciate ligament (MD-ACL) is a chronic degenerative process involving a hypertrophied ACL, which may lead to notch impingement syndrome. As a treatment method, there is consensus regarding arthroscopic resection for MD-ACL resulting in good clinical outcomes; however, additional notchplasty remains controversial. The purpose of this study was to investigate clinical outcomes after arthroscopic partial resection of the ACL and additional notchplasty performed to minimize volume reduction of the ACL. STUDY DESIGN: Level IIIb retrospective cohort study. METHODS: Of 1810 individuals who underwent knee arthroscopic surgery performed by the same surgeon between July 2011 and October 2020, 52 were included, while 10 were excluded due to a follow-up period of <1 year. Clinical data including pain location, terminal flexion or extension pain, range of motion (ROM), Lysholm knee score, and Hospital for Special Surgery (HSS) knee score were assessed pre- and postoperatively. Additionally, according to the resected volume of the ACL, patients were classified into two groups: <25% (Group 1), and 25-50% (Group 2). Clinical outcomes were compared between the two groups. RESULTS: There were 17 (40.5%) men and 25 (59.5%) women with a mean age of 53.9 years (range, 16-81 years) at the time of surgery. The mean duration of symptoms before surgery was 14.4 months (range, 3-66 months). Arthroscopic partial resection of the MD-ACL was performed in all patients, and concomitant notchplasty was performed in 36 (81.8%). All clinical scores improved postoperatively, and were statistically significant (p < 0.01). However, there was no significant difference in clinical outcomes between groups 1 and 2 classified according to the resected ACL volume. Recurrence of MD-ACL was recorded in only one patient, 11 months after arthroscopic treatment. No patients underwent ACL reconstruction because of symptoms of anterior instability. CONCLUSION: Arthroscopic partial resection of the ACL and concomitant notchplasty yielded satisfactory outcomes for the treatment of MD-ACL. Notchplasty may be an alternative procedure to avoid total ACL resection and postoperative instability.

A comparison of fasciocutaneous and adipofascial methods in the reverse sural artery flap for treatment of diabetic infected lateral malleolar bursitis.

PURPOSE: Infected lateral malleolar bursitis occurring as a diabetic complication requires debridement and flap surgery because it cannot be treated by conservative methods. The most accessible flap is the reverse sural artery flap, which can be harvested as a fasciocutaneous flap or an adipofascial flap. The purpose of this study was to compare the two types of flap methods performed in patients with diabetic infected lateral malleolar bursitis. METHODS: Twenty-nine cases of diabetic infected lateral malleolar bursitis treated with reverse sural artery flap between 2006 and 2017 were analyzed retrospectively. Fasciocutaneous flap methods were performed in 15 cases (group A), and adipofascial flap methods were performed in 14 cases (group B). Patients in the two groups did not differ in sex or age. The mean follow-up period was 16 months. RESULTS: All flaps survived. Infection was controlled at a mean of 2.4 months in both groups. At final follow-up, infection recurred in one case of each group, which was treated with antibiotics. No case developed an ulcer in the flaps. The patients were able to ambulate in regular shoes. All but one of the patients (28 patients) expressed satisfaction with the aesthetic appearance following treatment. No case required a debulking operation. CONCLUSION: Both the fasciocutaneous and adipofascial methods for reverse sural artery flaps were shown to be viable options for the control of diabetic lateral infection. In addition, the two groups did not differ in terms of appearance or complication rate following treatment.

Radiologic Comparison of Humeral Position according to the Implant Designs Following Reverse Shoulder Arthroplasty: Analysis between Medial Glenoid/Medial Humerus, Lateral Glenoid/Medial Humerus, and Medial Glenoid/Lateral Humerus Designs.

BACKGROUND: The currently available reverse shoulder arthroplasty (RSA) designs can be classified into medial glenoid/medial humerus (MGMH), lateral glenoid/medial humerus (LGMH), and medial glenoid/lateral humerus (MGLH) prosthesis designs. The purpose of this study was to radiologically analyze the effect of different RSA designs on humeral position following RSA. METHODS: A total of 50 patients who underwent primary RSA were retrospectively analyzed. Among 50 patients, 33 patients (group A: MGMH) underwent RSA with Aequalis system (Wright, Inc, Bloomington, MN, USA), 6 (group B: LGMH) with Aequalis system using bony increased offset, and 11 (group C: MGLH) with Aequalis Ascend Flex system. The acromiohumeral distance, acromioepiphyseal distance (AED), lateral humeral offset (LHO), LHO from the center of rotation (LHOCOR), and deltoid length were radiologically measured to quantify the distalization and lateralization of the humerus. RESULTS: The increment in postoperative AED was 19.92 ± 3.93 mm in group A, 24.52 ± 5.25 mm in group B, and 25.97 ± 5.29 mm in group C, respectively (p=0.001). The increment in postoperative LHO was 0.13 ± 6.30 mm, 8.00 ± 12.14 mm, and 7.42 ± 6.88 mm, respectively (p=0.005). The increment in postoperative LHOCOR was 20.76 ± 6.06 mm, 22.04 ± 5.15 mm, and 28.11 ± 4.14 mm, respectively (p=0.002). CONCLUSIONS: The radiologic analysis of the effect of different RSA designs on humeral position following RSA showed significant differences in the increment in postoperative AED, LHO, and LHOCOR between the 3 groups. Therefore, MGLH design seems to be more effective for humeral distalization and lateralization compared to original Grammont design.

Delayed infrarenal aortic pseudoaneurysm treated by endovascular stent graft in pyogenic spondylitis.

A 61-year-old male patient with pyogenic spondylodiscitis and epidural and psoas abscesses underwent posterior decompression, debridement, and instrumented fusion, followed by anterior debridement and reconstruction. Sudden onset flank pain was diagnosed 7 weeks postoperatively and was determined to be a pseudoaneurysm located at the aorta inferior to the renal artery and superior to the aortic bifurcation area. An endovascular stent graft was applied to successfully treat the pseudoaneurysm. Postoperative recovery was uneventful and infection status was stabilized.
