Metacarpal fractures comprise between 18-44 % of all hand fractures. Non-thumb metacarpals account for around 88 % of all metacarpal fractures, with the fifth finger most commonly involved [19]. The majority of metacarpal fractures are isolated injuries, which are simple, closed, and stable. While many metacarpal fractures do well without surgery, there is a paucity of literature and persistent controversy to guide the treating physician on the best treatment algorithm. The purpose of this article is to review non-thumb metacarpal anatomy and treatment protocols for nonoperative management of stable fractures, and compare existing literature on surgical techniques for treatment of acute fractures and complications.

Studies were performed evaluating the role of Smad3, a transcription factor mediating canonical TGF-β signaling, on scarring and adhesion formation using an established flexor digitorum longus (FDL) tendon repair model. In unoperated animals the metatarsophalangeal (MTP) range of motion (ROM) was similar in Smad3−/− and wild type (WT) mice while the basal tensile strength of Smad3−/− tendons was significantly (39%) lower than in WT controls. At 14 and 21 days following repair Smad3−/− MTP ROM reached approximately 50% of the level of the basal level and was twice that observed in WT tendon repairs, consistent with reduced adhesion formation. Smad3−/− and WT maximal tensile repair strength on post-operative day 14 was similar. However, Smad3−/− tendon repairs maximal tensile strength on day 21 was 42% lower than observed in matched WT mice, mimicking the relative decrease in strength observed in Smad3−/− FDL tendons under basal conditions. Histology showed reduced "healing callus" in Smad3−/− tendons while quantitative PCR, in situ hybridization, and immunohistochemistry showed decreased col3a1 and col1a1 and increased MMP9 gene and protein expression in repaired Smad3−/− tendons. Thus, Smad3−/− mice have reduced collagen and increased MMP9 gene and protein expression and decreased scarring following tendon FDL tendon repair.

Given the complexity of these procedures, the high recurrence rate, and the likelihood of complications, methylmethacrylate is contraindicated in 1-stage cranioplasty and soft-tissue reconstruction in high-risk patients. For unfavorable local conditions (eg previous infection, radiotherapy), the surgeon can either postpone the cranioplasty until the soft-tissue reconstruction has healed, or use a nonanatomical titanium mesh alone. The soft-tissue flap should be harvested of larger dimensions than anticipated.

High-pressure injection injuries to the hand can result in permanent impairment. Proper diagnosis and urgent treatment are essential for a good outcome.

The mallet finger is a frequently encountered fingertip injury that leads to extensor lag of the distal phalanx. Classification systems stratify these injuries as ranging from soft-tissue disruption of the extensor mechanism alone to those that have articular involvement and volar subluxation. The management of mallet finger injuries varies based on injury pattern and surgeon preference. These treatment options include splinting regimens, closed reduction and percutaneous pinning, and open reduction and internal fixation. Although the final goal of treatment is to establish a congruent joint, the efficacy of each treatment modality has been shown to vary.

Objectives: The Patient-Reported Outcomes Measurement Information System (PROMIS) is growing in popularity as healthcare shifts towards a value-based system. However, it remains unclear if PROMIS use improves the patient experience. The aim of the present study was to determine if PROMIS use as part of routine orthopaedic clinical care is associated with improved patient experience, as measured by the Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CGCAHPS) survey.Methods: All patient visits to an orthopaedic surgery clinic at a single academic medical centre between February 2015 and September 2016 were reviewed.Accounting for known patient factors that have an impact on clinic visit satisfaction, CGCAHPS scores were compared between patients who had PROMIS used as part of their routine care and those who had not had PROMIS used as part of their routine care. A p-value of <0.05 was considered significant.Results: A total of 8,607 patient visits fitted our inclusion criteria. Of these, surgeons elected not to use PROMIS in 8,422 patient encounters, leaving 185 patient visits in which PROMIS was actively used. When PROMIS was used, patients were significantly more likely to feel that the provider had spent enough time with them, to recommend this provider office to another patient and to rate the provider significantly higher on a scale from 0 to 10. Although not significant, a trend was found between use of PROMIS and whether a patient felt that a provider explained health information in way that the patient understood.Conclusions: PROMIS use in an orthopaedic clinic visit can have a positive impact on the patient experience, which is currently part of a number of alternative payment models.

This study indicates that corticosteroid injections are a useful treatment for de Quervain's tenosynovitis, leading to treatment success 73.4% of the time within 2 injections. This study also suggests that female sex and BMI >30 are associated with increased treatment failure.
