Project description:BackgroundSuccessful short-term results of diaphyseal ulna shortening osteotomy are documented in both idiopathic and post-traumatic ulnar impaction.Questions/purposesThe purpose of this study was to evaluate the mid-term outcomes of ulnar shortening osteotomy with respect to radiographic assessment of corrected alignment and healing as well as patient satisfaction, pain, and function assessed using the Disability of the Arm, Shoulder, and Hand (DASH) score.Patients and methodsThis retrospective case series included follow-up of 33 patients with ulnar impaction syndrome following ulna shortening osteotomy at a minimum of 5 years. Patient-rated outcomes included satisfaction, pain assessment, and DASH score. Pre- and postoperative radiographs were reviewed to quantify ulnar variance and osteotomy union rates. Subsequent operations were also recorded.ResultsAverage follow-up was 10 years (range, 5-20 years). Eighty-eight percent of patients reported they were either satisfied or very satisfied with the procedure and 91% reported they would have the same procedure again. Average pain rating was 2 out of 10 at final follow-up. The mean DASH score was 11 (range, 0-39). Removal of hardware was performed in 10 patients (30%). The overall rate of reoperation was 45%.ConclusionsUlna shortening osteotomy yields reliable midterm satisfaction and pain relief in patients with idiopathic and post-traumatic ulnar impaction syndrome. Reoperation is frequent. Consistent with results of short-term follow-up, plate irritation requiring removal remains the most common cause for reoperation over time.

Project description:BackgroundUlna shortening osteotomy (USO) for ulnar impaction syndrome (UIS) aims to improve pain and function by unloading the ulnar carpus. Previous studies often lack validated patient-reported outcomes or have small sample sizes. The primary objective of this study was to investigate patient-reported pain and hand function at 12 months after USO for UIS. Secondary objectives were to investigate the active range of motion, grip strength, complications, and whether outcomes differed based on etiology.Materials and methodsWe report on 106 patients with UIS who received USO between 2012 and 2019. In 44 of these patients, USO was performed secondary to distal radius fracture. Pain and function were measured with the Patient Rated Wrist/Hand Evaluation (PRWHE) before surgery and at 3 and 12 months after surgery. Active range of motion and grip strength were measured before surgery and at 3 and 12 months after surgery. Complications were scored using the International Consortium for Health Outcome Measurement Complications in Hand and Wrist conditions (ICHAW) tool.ResultsThe PRWHE total score improved from a mean of 64 (SD = 18) before surgery to 40 (22) at 3 months and 32 (23) at 12 months after surgery (P < 0.001; effect size Cohen's d = -1.4). There was no difference in the improvement in PRWHE total score (P = 0.99) based on etiology. Also, no clinically relevant changes in the active range of motion were measured. Independent of etiology, mean grip strength improved from 24 (11) before surgery to 30 (12) at 12 months (P = 0.001). Sixty-four percent of patients experienced at least one complication, ranging from minor to severe. Of the 80 complications in total, 50 patients (47%) had complaints of hardware irritation, of which 34 (32%) had their hardware removed. Six patients (6%) needed refixation because of nonunion.ConclusionWe found beneficial outcomes in patients with UIS that underwent USO, although there was a large variance in the outcome and a relatively high number of complications (which includes plate removals). Results of this study may be used in preoperative counseling and shared decision-making when considering USO.Level of evidenceTherapeutic III.

Project description:Background Ulnar impaction syndrome is a condition in which the ulna impacts on the ulnar carpus. This most commonly occurs when the ulna is longer than the radius, but it can also occur in wrists with ulnar neutral and ulnar negative variance. Materials and Methods In this paper we outline our surgical technique for ulnar shortening osteotomy. A previously published retrospective case series of 28 patients treated at our center is presented. Fifty consecutive patients who underwent ulnar shortening osteotomy (USO) for ulnar impaction syndrome were approached for study, and 28 consented to review. Mean preoperative ulnar variance was +2.3 mm, and mean postoperative ulnar variance was -0.8 mm. Mean follow-up time was 21.2 months (8 to 41 months) and ten of 28 were receiving workers' compensation. Mean preoperative pain score (visual analog scale; VAS) was 7.9. Univariate analysis was performed to assess clinical and demographic data. In addition, subgroup analysis of workers' compensation patients and smokers was performed. Description of Technique A longitudinal incision over the subcutaneous border of the ulna is used to expose the ulna between the distal and middle third of the ulna from the ulna styloid. Preoperative posteroanterior (PA) X-rays are reviewed to determine the amount of shortening required, with a goal of creating -2 mm variance postoperatively. A 6-hole dynamic compression plate is predrilled distally prior to performing two oblique osteotomies separated by the desired shortening length. The fragments are reduced, controlling for rotation, and plated using compression. In some cases, a lag screw is employed across the oblique osteotomy site. Results Mean pain scores were significantly reduced postoperatively (VAS 7.9 versus 3.1, P < 0.0001). The mean Disabilities of the Arm, Shoulder, and Hand (DASH) score was 37.2 postoperatively. Flexion, extension, and supination were reduced compared with the contralateral unaffected extremity (84.6%, 85.3%, and 86.9% of normal). Patients receiving workers' compensation and smokers had significantly more pain postoperatively (VAS 5.2 vs. 2.0, P = 0.0002 and VAS 4.4 vs 2.4, P < 0.05, respectively). Eleven of 28 patients required hardware removal for plate irritation, and five of 28 patients had a nonunion. Conclusion We present our surgical technique for ulnar shortening osteotomy. Pain was significantly improved in our population; however, patients receiving workers' compensation and smokers had less improvement in pain and higher disability scores.

Project description:Background Malunion is a common complication of distal radius fractures. Ulnar shortening osteotomy (USO) may be an effective treatment for distal radius malunion when appropriate indications are observed. Methods The use of USO for treatment of distal radius fracture malunion is described for older patients (typically patients >50 years) with dorsal or volar tilt less than 20 degrees and no carpal malalignment or intercarpal or distal radioulnar joint (DRUJ) arthritis. Description of Technique Preoperative radiographs are examined to ensure there are no contraindications to ulnar shortening osteotomy. The neutral posteroanterior (PA) radiograph is used to measure ulnar variance and to estimate the amount of ulnar shortening required. An ulnar, mid-sagittal incision is used and the dorsal sensory branch of the ulnar nerve is preserved. An USO-specific plating system with cutting jig is used to create parallel oblique osteotomies to facilitate shortening. Intraoperative fluoroscopy and clinical range of motion are checked to ensure adequate shortening and congruous reduction of the ulnar head within the sigmoid notch. Results Previous outcomes evaluation of USO has demonstrated improvement in functional activities, including average flexion-extension and pronosupination motions, and patient reported outcomes. Conclusion The concept and technique of USO are reviewed for the treatment of distal radius malunion when specific indications are observed. Careful attention to detail related to surgical indications and to surgical technique typically will improve range of motion, pain scores, and patient-reported outcomes and will reduce the inherent risks of the procedure, such as ulnar nonunion or the symptoms related to unrecognized joint arthritis.

Project description:UNLABELLED: Ulnar-sided wrist pain resulting from ulnar impaction is common. We describe a new cartilage-retaining wafer resection osteotomy designed to keep the cartilage intact and decompress the ulnocarpal articulation without requiring internal fixation. We retrospectively reviewed seven patients with ulnar impaction who had the procedure. The minimum followup was 14 months (mean, 30 months; range, 14-38 months). The mean change in ulnar variance was -1.29 mm. Patients showed radiographic healing by a mean of 11 weeks. Our preliminary results suggest the cartilage-retaining wafer resection osteotomy may be an effective way to unload the ulnocarpal joint without requiring internal fixation or destruction of the distal ulna cartilage. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Project description:Background The purpose of ulnar shortening osteotomy is literally to shorten the ulna. It can tighten the triangular fibrocartilage complex (TFCC), ulnocarpal ligaments, and interosseous membrane. Nowadays, this method is used to treat ulnar-sided wrist pain, for which we have also started to use a treatment algorithm. The purpose of this study was to review the long-term and clinical results based on our algorithm. Materials and Methods We retrospectively reviewed 30 patients with ulnocarpal impaction syndrome after a minimum follow-up of 5 years (Group A) and then retrospectively evaluated 66 patients with recalcitrant ulnar wrist pain treated based on our algorithm (Group B). Description of Technique Ulnocarpal abutment was confirmed arthroscopically. The distal ulna was approached through a longitudinal incision between the extensor carpi ulnaris and flexor carpi ulnaris. We performed a transverse resection of the ulna fixed with a small locking compression plate. The contralateral side served as the reference for the length of shortening (mean, 2.4 mm; range, 1-5 mm). Disappearance of ulnar abutment was then confirmed again arthroscopically. Results (Group A) Most patients showed good long-term clinical results. About half of the patients showed a bony spur at the distal radioulnar joint (DRUJ), but the clinical results did not significantly correlate with presence of bony spurs. Radiological parameters wre not related to the presence of bony spurs. (Group B) Twenty-four of the 66 patients investigated prospectively underwent an ulnar shortening osteotomy, with all showing good clinical results at 18 months postoperatively. Conclusions Ulnar shortening osteotomy can change the load of the ulnar side of the wrist and appears useful for ulnar-sided wrist pain in the presence of ulnar impaction. Level of evidence IV.

Project description:Background Ulnar sided wrist pain is a commonly encountered complaint of the hand surgeon, and ulnar impaction is a common cause. Surgical treatment aims to reduce the force transmitted through the ulna and traditionally includes diaphyseal ulnar shortening osteotomy and the "wafer" procedure. These procedures have known shortcomings. We describe an alternative option known as the distal metaphyseal ulnar shortening osteotomy (DMUSO). Materials and Methods Retrospective review of eight procedures was undertaken to assess radiographic healing, objective measurements of wrist and forearm motion, grip and pinch strength, and subjective measures of Disabilities of the Arm, Shoulder, and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), and Michigan Hand Outcomes Questionnaire (MHQ) at a minimum of 12 months following surgery. Description of Technique A wedge osteotomy is made in the osteochondral region of the distal metaphysis of the ulna, and a headless compression screw is used for fixation. Results Five women and three men underwent DMUSO with average follow up at 13 months; the dominant wrist was affected in 7 of 8 patients. The affected wrist had less motion in all planes, and grip and pinch strength was also less in the affected wrist, but only wrist extension was significantly different from the contralateral side. These findings likely did not have an effect on the clinical outcome. Subjective outcomes included average DASH score of 13 (0-35), PRWE 19 (40-11), and MHQ score of 88 (85-100). Conclusions DMUSO is a viable option for patients with ulnar impaction syndrome. It requires intra-articular exposure of the distal radioulnar joint (DRUJ) but is less invasive then diaphyseal shortening. It permits early and reliable return of joint motion and function while avoiding the potential need for hardware removal by using a buried screw.

Project description:ObjectiveTo evaluate the outcomes of total hip arthroplasty (THA) with subtrochanteric femoral shortening osteotomy for high hip dislocation.MethodsIn this retrospective study, the results of 24 primary THAs with acetabular reconstruction and subtrochanteric femoral shortening osteotomy in 21 patients with high hip dislocation were evaluated. The acetabula were reconstructed with cemented or uncemented cups and bone grafting. Transverse subtrochanteric femoral shortening osteotomies were applied and the osteotomy sites treated by bone grafting and cable fixation. Assessment was by Hip Harris scores and radiographic evaluation.ResultsThe mean follow-up time was 42 months (18-108 months), three cases being lost to follow-up 18-27 months postoperatively. The HHS improved from 47.5 ± 8.7 to 88.5 ± 3.1. The mean length of femoral segments removed was 2.5 ± 0.8 cm (range, 1.0-4.5 cm) and mean acetabular inclination 43° ± 5° (range, 31°-54°). Caudalization of the femoral head center was 3.2 ± 3.0 mm (range, -3 to 12 mm) and lateralization 4.0 ± 4.0 mm (range, -9 to 11 mm). Mean greater trochanter height relative to theoretical hip center was 5.2 ± 1.0 cm (range, 3.5-7.1 cm) preoperatively and 0.2 ± 0.6 cm (range, -0.9 to 1.2 cm) postoperatively. Intraoperative trochanteric fractures occurred in three cases and sciatic nerve palsy in one.ConclusionTHA with subtrochanteric femoral shortening osteotomy is an effective technique for treating high hip dislocation. Its advantages include improvement in limb imbalance and decreased risk of sciatic nerve injury.

Project description:Ulnar shortening osteotomy is an established and frequently performed surgical procedure in wrist surgery. The technical aspects of the procedure have continued to develop in recent years, with instruments and implants being developed specifically for this purpose. Ulnar shortening osteotomy is required for different clinical indications and situations. These varying indications demand different amounts of shortening, but all must be precise and accurate. Controversy exists as to how this can best be achieved in terms of the location for osteotomy, the surgical approach and geometry of the osteotomy, as well as which implant to use to provide optimal stability. The goal of all techniques (besides successfully resolving the underlying problem) is to achieve reliable and rapid bone union without compromising early functional rehabilitation and also to avoid hardware complications. The AO Hand Expert Group has developed a specialized instrumentation system with dedicated and specifically designed implants to ensure exact and accurate cutting with precise and rigid stabilization of the ulna. The matched drill guides and double-blade saws allow accurate completion of the planned amount of shortening together with precise coaptation of the osteotomy fragments. The specific ulnar osteotomy LCP (locking compression plate) combines maximum stability with minimum bulk and soft tissue irritation. The features of the implant, its surgical technique, and early results are described.

Project description:BackgroundThe distraction osteogenesis procedure has a high potential to treat bone defect problems. The alternative technique to treat nonunion associated with a bone defect is the acute shortening and re-lengthening (ASRL) procedure. This study aimed to evaluate the outcome of ASRL procedure with a monorail fixator to treat femur/tibia nonunion associated with the bone defect.MethodRetrospective analysis was performed to patients who received ASRL procedure with monorail fixator for femur or tibia nonunion from October 2018 to October 2020 at Prof. Dr. R. Soeharso Orthopaedic hospital. One case was loss to follow-up and excluded from the study. The rest of 16 cases were included for further analysis. The evaluation was performed to the demographic, intraoperative procedure, problems/complications, additional procedure, and final outcome.ResultsThere were 13 male and three female patients with age ranged from 16 to 64 years old. The follow-up period ranges 9-31 months. ASRL procedures performed to 6 femur and 10 tibias. The problems/complications: two cases with problems associated with callus formation, two cases of fracture at corticotomy site, one case of skin necrosis, one case of osteomyelitis, one case of malrotation. Additional surgical procedures were needed 5/16 (31.2%) cases. Evaluation at the final follow-up period showed 14/16 (87.5%) cases had a complete bone union.ConclusionsAcute shortening and re-lengthening (ASRL) could be reliable as a method of treatment for femur/tibia nonunion associated with the bone defect. Several possible complications need to be considered prior to perform this procedure.
