Background: Traumatic ulnar nerve injuries often result in significant loss of motor and sensory function, negatively impacting patients' quality of life. Physical rehabilitation is crucial for recovery, but standardized treatment protocols are lacking. This study aims to systematically review rehabilitation techniques to identify future research direction and improve existing protocols for ulnar nerve injury patients.

Methods: PubMed, Embase, CINAHL, Cochrane CENTRAL, Web of Science, and Scopus were queried from inception until July 31, 2023. Articles containing axonotmesis or neurotmesis injuries of the ulnar nerve were included. Reviews, opinions, editorials, technical reports without clinical outcomes, conference abstracts, non-English text, nonhuman studies, and studies without adult patients were excluded. Three independent reviewers performed screening and data extraction using Covidence, and risk of bias assessments utilizing Cochrane and JBI tools. Because of article heterogeneity, a narrative review was conducted. The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database, registration number CRD42023442016.

Results: This systematic review included one randomized controlled trial and four observational studies (103 patients), which exhibited differences in study quality. Overall, motor and sensory outcomes improved after rehabilitation. Rehabilitation techniques varied widely, and early sensory reeducation appeared to improve sensory function. Only two studies included patient-reported outcomes.

Conclusions: Diverse rehabilitation techniques are used to address ulnar nerve injuries. The low number of included studies, differences in study quality, and small sample size underscore the need for larger and more inclusive studies to improve functional recovery after ulnar nerve injuries. Future research should consider the impact of patient and injury characteristics to develop comprehensive treatment guidelines for these patients.

Background: Operative microscopes are traditionally draped in single-use plastic to prevent infection theoretically. The necessity of this routine in breast free flap surgery is unclear. Alternatively, sterile wrapping of microscope handles would reduce operating room waste and provide a more cost-effective and environmentally sustainable approach to sterility. This study aimed to determine whether the draping technique used during abdominally based free flaps (Ab-FF) influenced the rate of surgical site infections.

Methods: We conducted a retrospective review of Ab-FF performed consecutively between March 2017 and August 2022. Patient demographics, comorbidities, perioperative data, and postoperative complications were collected. The primary outcomes included postoperative surgical site infections and environmental impact.

Results: Of the 281 identified breasts reconstructed with Ab-FF, operating microscopes were sterilely covered with microscope drapes (n = 215) or handle covers (n = 66) composed of polyethylene-based plastic. Overall, postoperative infections occurred in 9.3% of cases (n = 26) in either the recipient breast (n = 11, 3.9%) or abdominal donor site (n = 15, 5.3%), primarily due to S. aureus and Streptococcus species . The handle (n = 6, 9.1%) and drape (n = 20, 9.3%) cohorts had similar infection rates with no sequelae of operative complications. In multivariate analysis, radiation was the only independent predictor of postoperative infection, while bilateral reconstructions were independently protective. Replacing a microscope drape with a handle reduces carbon emissions by 1276 grams of CO 2 and direct costs by $7.84 per item.

Conclusions: The principles of "Lean and Green" surgery prioritize reducing operating room generated waste to achieve financial and environmental sustainability. This cohort study of 281 breast free flaps demonstrates that switching from whole microscope draping to handle wrapping was not associated with an increased rate or odds of infection. Adopting a microscope handle wrapping protocol decreased the carbon footprint and operative costs. The results of this study offer evidence to support adoption and further exploration of pragmatic, cost-effective, and sustainable approaches to microsurgical breast reconstruction.

Introduction: Scaphoid nonunion is a typical complication of scaphoid fractures, with the nonunion rate varying by the location of the scaphoid. The current widely used method for treating scaphoid nonunion, which is challenging for surgeons, is the headless compression screw (HCS). Various surgical approaches, such as the scaphoid plate, have been proposed to address the problem of screw fixation; however, no consensus exists regarding the optimal treatment method. This study focused on analyzing appropriate treatment methods based on the anatomical location of the scaphoid nonunion.

Methods: Ninety-seven patients with scaphoid nonunion were treated between 2008 and 2023. All patients underwent treatment using 1 HCS or scaphoid volar locking plate with nonvascularized bone graft from the distal radius depending on the scaphoid's location. The scaphoid angle and bone union were confirmed using radiological examinations. The clinical evaluations included range of motion, pain, grip strength, and functional wrist scores.

Results: Fifty-seven patients were included in the final analysis. In the screw group, 26 patients (26/42 [62%]) obtained a bone union, and all 15 patients (15/15 [100%]) in the plate group obtained a union ( P = 0.005). In the waist group, 16 patients with screw (16/25 [64%]) and 8 using a plate (8/8 [100%]) showed bony healing. In the proximal group, 3 patients with HCS (3/9 [33%]) and 4 using plate (4/4 [100%]) showed bone union. In the distal group, 7 patients with a screw (7/8 [87%]) and 3 with the plate (3/3 [100%]) showed bone union. Significant differences were found in the waist ( P = 0.047) and proximal groups ( P = 0.026), but not in the distal group ( P = 0.521). All groups showed improved radiological angles associated with the scaphoid and better clinical outcomes postoperatively.

Conclusions: Plate fixation was overall superior to screw fixation for scaphoid nonunion, especially in the waist and proximal poles, providing better union rates and stability. For the distal group, both methods are effective, with the choice depending on the surgeon's expertise and patient factors. The results highlight the importance of the lesion's anatomical location in selecting the appropriate fixation method.

Background: Hand injuries pose challenges due to complexity and aesthetic-functional concerns. Dorsum of hand injuries are difficult to treat due to thin skin cover and increased propensity to exposure of underlying structures. Perforator-based flaps can provide better outcomes with minimal donor site morbidity. This study aims to bridge the gap in anatomical knowledge and explore the potential benefits of dorsal carpal artery perforator flap.

Materials and methods: A prospective study was done from July 2021 to June 2023, focused on study of dorsal carpal artery perforators on 12 fresh frozen cadaveric hands. Anatomical study involved injection of red latex into arteries at the wrist, followed by dissection and measurements. During the clinical phase, we used the inferences gained from the anatomical study to identify and mark perforator of dorsal carpal arteries. We performed V-Y advancement flap based on the DCPs in 5 patients who had dorsum of hand defects due to trauma.

Results: The study was carried out on 6 fresh frozen cadavers (12 hands). Anatomical findings revealed the anatomical location, caliber, and consistent number of dorsal carpal artery perforators supplying the dorsum of the hand arranged in 2 rows. Clinically, we applied this insight to create V-Y flaps in 5 patients with successful outcomes, thus, offering DCP-based flap as an alternative to distant flaps.

Conclusion: DCP-based flaps offer an efficient solution for reconstructing proximal hand defects over the dorsum, with minimal complications, enhancing our understanding of hand reconstruction options. The study's comprehensive anatomical insights and clinical outcomes contribute to improving hand defect management and surgical techniques.

Background: Local flaps remain a valuable reconstructive tool as a means for limb salvage for patients with advanced arterial disease. Our single-center, retrospective cohort study aims to compare the outcomes of different patterns of blood flow affected by vascular disease to pedicles in local flap reconstruction of the foot and ankle.

Methods: A retrospective review of 92 patients and 103 flaps was performed. On angiograms, pattern of blood flow to the flap pedicle was determined to be direct inline flow (DF) or indirect flow (IF). Patterns of IF were either by arterial-arterial connections (AC) or unnamed randomized collaterals (RC). Primary outcomes were immediate flap success and limb salvage. Comparative analyses were performed using the χ2 and Fisher tests for categorical variables.

Results: Among all flaps, 73.8% (n = 76/103) had DF and 26.2% (n = 27/103) had IF. Both groups experienced similar rates of immediate flap success (DF = 97.3% vs IF = 92.6%, P = 0.281) and limb salvage (DF = 75.% vs IF = 66.7%, P = 0.403). However, the rate of contralateral amputation was significantly higher in the IF group (26.9% vs 5.3%, P = 0.006). When comparing the 3 distinct patterns of blood flow (DF vs AC vs RC), pedicled flaps were more commonly supplied by DF and AC, while random pattern flaps were more commonly supplied by RC (P = 0.042).

Conclusions: Alternative routes of revascularization can maintain local flap viability and achieve similar rates of limb salvage but risks contralateral amputation. We found that pedicled and local muscle flaps require inline blood flow or blood supply by ACs. Meanwhile, random pattern flap can be supported by random collaterals.

Background: Soft tissue procedures are often crucial for normalizing the long-term facial appearance in patients with syndromic craniosynostosis, yet they are underrepresented in the literature and existing treatment algorithms. This study evaluated secondary soft tissue surgeries in relation to skeletal operations in patients with syndromic craniosynostosis.

Methods: A retrospective review evaluated patients with syndromic craniosynostosis treated at a tertiary children's hospital from 2003 to 2023. Craniofacial skeletal and soft tissue procedures were assessed for timing and frequency. Skeletal surgeries included redo fronto-orbital advancements, monobloc advancement/distraction ± facial bipartition, and LeFort III or III/I advancement/distraction. Soft tissue surgeries encompassed oculoplastic procedures, scalp reconstruction, fat grafting, and septorhinoplasty.

Results: Of 106 patients with syndromic craniosynostosis, 57 (57.8%) underwent ≥1 secondary skeletal operation, and 101 (95.3%) underwent ≥1 soft tissue procedures, averaging 3.7 ± 3.3 soft tissue procedures per patient. Patients who underwent secondary forehead advancement had significantly higher rates of subsequent lateral canthopexy (71.4% vs 25.6, P < 0.001), ptosis reconstruction (17.9% vs 7.7%, P = 0.025), and frontotemporal fat grafting (50.0% vs 15.4%, P < 0.001) than those who did not. Patients who underwent midface advancement surgery had significantly higher rates of subsequent lateral canthopexy (65.4% vs 11.1%, P < 0.001), medial canthopexy (7.7% vs 0.0%, P = 0.038), scalp reconstruction (36.5% vs 16.7%, P = 0.020), frontotemporal fat grafting (34.6% vs 14.8%, P = 0.018), malar fat grafting (11.5% vs 0.0%, P = 0.010), and septorhinoplasty (26.9% vs 1.9%, P < 0.001) than those who did not. Specifically, LeFort III or III/I advancement/distractions were significantly associated with higher rates of subsequent septorhinoplasties (33.3% vs 1.6%, P < 0.001). The mean follow-up was 10.2 ± 7.0 years.

Conclusions: This study revealed an intricate interplay between skeletal and soft tissue surgery in patients with syndromic craniosynostosis. Exploring techniques to reduce the need for further corrective surgery and anticipating necessary secondary interventions may improve patient counseling and outcomes.

Background: Pediatric open tibial fractures represent a challenging subset of injuries with limited literature to guide management. For children, the epidemiology, management, and outcomes of tibial-shaft fractures have not been fully described.

Methods: A retrospective analysis of the Trauma Quality Improvement Program Data Bank from 2017-2020 was used to query demographics, injury patterns, and management strategies in pediatric open tibial fractures. Fractures were compared by age group (0-5, 6-12, 13-17 years) and type (I/II vs type III). A subgroup analysis was performed on patients with type III open fractures.

Results: A total of 3480 open tibial fractures were identified, 3049 were type I/II, and 431 were type III. Motor vehicle accidents (48%) were the most common mechanism of injury (P < 0.001). Subanalysis of 128 type IIIb/c tibial fractures revealed local flap reconstruction (25%) skin graft (25%), and free tissue transfer were the most common management strategies and soft-tissue coverage was achieved after 162 hours (interquartile range = 109-231). Negative pressure wound therapy was utilized in 63% of cases but used in isolation in only 23% of cases. Immediate fixation with intramedullary nailing was more frequently used in the 13-17 age group while plate fixation was more commonly used in younger age groups.

Conclusions: Soft-tissue management patterns following open tibial shaft fractures mirror those seen in adult cohorts. The median time to achieve soft-tissue coverage exceeds the traditional 72-hour target advocated by Godina. Age-based variation is seen in orthopedic management of these fractures based on growth maintenance concerns.

Objective: The aim of the study is to investigate the effect and feasibility of using absorbable plate instead of frontal and orbital bar and inverted U-shaped osteotomy to correct the widening of orbital distance.

Methods: The surgical effect and feasibility of using absorbable plate instead of frontal and orbital bridge plus inverted U-osteotomy for orbital widening syndrome in seven cases between January 2019 and February 2022 were retrospectively analyzed. First, the surgical procedure for orbital hypertelorism was inverted U-shaped orbital osteotomy, and a frontal bone flap was removed, exposing the superior orbital margin and the orbital circumference, and the orbital bone was directly cut off by inverted U-shaped osteotomy. The widened bone in the middle of the orbit was removed, and a long absorbable plate was used to replace the orbitofrontal bridge. The two sides of the orbit were fixed on the absorbable plate, and the absorbable plate was fixed on the rear skull. The clinical effect of treatment, complications (such as cerebrospinal fluid leakage and infection), safety, and feasibility of surgery were evaluated.

Results: Using absorbable plate instead of fronto-orbital bridge achieved the effect of orbitofrontal bridge, without orbital distance widening, cerebrospinal fluid leakage, and intracranial infection. Operating time was reduced. There was no metal fixation, and there was no risk of a second operation.

Conclusions: The effect of replacing the frontal-orbital bridge with an absorbable plate and inverted U-shaped osteotomy is positive, the operation time is short, and the orbital distance is clearly improved. This approach can replace the traditional orbital-distance operation, and the incidence of postoperative cerebrospinal fluid leakage and infection is low. Long-term follow-up results are stable.
