Fibrin glue was found to increase the strength of conduit-assisted primary digital nerve repairs. Furthermore, the number of sutures correlated to the strength of the repair. Fibrin glue may be added to a conduit-assisted primary digital nerve repair to maintain strength and allow fewer sutures at the primary coaptation site.
Neuromas of the hand and wrist are common causes of peripheral nerve pain. Neuromas are formed after the nerve sustains an injury, and they can be debilitating and painful. The diagnosis is made by a thorough history and physical examination. The treatment options are quite varied, but conservative measures tailored to the patient should be initiated first. No surgical treatment has been proven superior to others or to nonsurgical treatment.
Background: Patient-reported outcome measures (PROMs) are critical and frequently used to assess clinical outcomes to support medical decision-making. Questions/Purpose: The purpose of this meta-analysis was to compare differences in the modes of administration of PROMs within the field of orthopaedics to determine their impact on clinical outcome assessment. Patients and Methods: The PubMed database was used to conduct a review of literature from 1990 to 2018 with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. All articles comparing PROMs for orthopaedic procedures were included and classified by the mode of administration. Each specific survey was standardized to a scale of 0 to 100, and a repeated random effectsmodel meta-analysis was conducted to determine the mean effect of each mode of survey. Results: Eighteen studies were initially included in the study, with 10 ultimately used in the meta-analysis that encompassed 2384 separate patient survey encounters. Six of these studies demonstrated a statistically notable difference in PROM scores by mode of administration. The meta-analysis found that the standardized mean effect size for telephone-based surveys on a 100-point scale was 71.7 (SE 5.0) that was significantly higher (P , 0.0001) than survey scores obtained via online/tech based (65.3 [SE 0.70]) or self-administered/paper surveys (61.2 [SE 0.70]). Conclusions: Overall, this study demonstrated that a documented difference exists in PROM quality depending on the mode of administration. PROM scores obtained via telephone (71.7) are 8.9% higher than scores obtained online (65.3, P , 0.0001), and 13.8% higher than scores obtained via self-administered on paper (61.8, P , 0.0001). Few studies have quantified statistically notable differences between PROM scores based solely on the mode of acquisition in orthopaedic
The distal radioulnar joint (DRUJ) allows supination and pronation of the distal forearm and wrist, an integral motion in everyday human activity. DRUJ injury and chronic instability can be a significant source of morbidity in patients’ lives. Although often linked with distal radius fractures, DRUJ injury may occur in a variety of other upper extremity injuries, as well as an isolated pathology. Diagnosis of this injury requires the clinician to have a high index of suspicion and low threshold for clinical testing and further imaging of the DRUJ. The purpose of this article is to provide a review on DRUJ anatomy and biomechanics, to discuss common diagnostic and treatment modalities, and to identify common injuries associated with DRUJ instability.
An ideal rotator cuff repair maximizes the tendon-bone interface and has adequate biomechanical strength that can withstand a high level of demand. Arthroscopic transosseous-equivalent rotator cuff repairs have become popular and have been shown to be superior to many other methods of fixation. We present an alternative method of repair for large crescent rotator cuff tears that combines 2 well-known methods of fixation: modified SpeedBridge (Arthrex, Naples, FL) and double-pulley techniques. These 2 repair constructs were combined to provide the greatest amount of compression across the footprint while also providing rigid fixation. Ultimately, this can provide an optimal environment for healing in otherwise significant injuries.
Total elbow arthroplasty (TEA) is a well-established treatment for end-stage rheumatoid arthritis of the elbow. With improved surgical techniques and implant designs, TEA is also effective in treating elbow osteoarthritis, posttraumatic arthritis, distal humerus nonunion, and comminuted distal humerus fractures in the elderly population. There have been multiple reports of greater than 90% survival rate, free of reoperation at 10 years. We present a case of early failure of TEA caused by coronoid impingement, to provide a surgical pearl for others to avoid this complication.
Background The anconeus is a small muscle located on the posterior elbow originating on the lateral epicondyle and inserting onto the proximal-lateral ulna that functions as an elbow extensor as well as dynamic stabilizer. The blood supply is tri-fold: medial/middle collateral artery (MCA), recurrent posterior interosseous artery (RPIA), and less commonly found, the posterior branch of the radial collateral artery. The anconeus has become a popular option for local soft tissue coverage about the elbow (distal triceps, olecranon, proximal forearm). The average defect size for consideration of local anconeus flap coverage is 5–7cm2. The aim of the study was to determine safe dissection parameters of the anconeus as well as map arterial pedicles to achieve successful local harvest of the muscle without devascularization. Materials and Methods 8 fresh frozen cadaveric arms (all male, average age 63 years – 4 left arms, 4 right arms) from scapula to fingertip were obtained. First, the radial, ulnar and axillary arteries were dissected and isolated. The radial and ulnar arteries were transected. 100cc normal saline was injected through the axillary artery, sequentially clamping the radial followed by the ulnar artery so that adequate flow could be seen through all vessels. 100cc mixture of Biodür and hardener (10:1) was mixed and injected into the axillary artery. We first allowed free flow through both the ulnar and radial vessels followed by clamping of these vessels. This allowed the pressure to build up and fill the smaller vessels in the arms. After injection, the axillary artery was then clamped and the specimens were left to harden for 24–48 h. After hardening, dissection was performed by making a curvilinear incision centred over the lateral epicondyle. The anconeus was identified and the interval between the anconeus and ECU was then confirmed. Measurements of the anconeus muscle were taken. Blunt dissection was carried between anconeus and ECU until the RPIA was identified and protected. We isolated the MCA by dissecting proximally. This was found to run with the nerve to the anconeus. Once this vessel had been protected, the muscle reflected from distal to proximal staying along its ulnar border. The branches of the RPIA were ligated and the dissection was continued proximally. Measurements of the distances of the RPIA, MCA were taken. Results The average distance of olecranon to muscle tip was 95.0mm. The average distance of lateral epicondyle (LE) to muscle tip was 90.8mm. The average distance of LE to olecranon was 49.8mm. The average location of the RPIA was 63.mm when measuring LE to vessel, 68.3mm when measuring olecranon to vessel, 18.3mm when measuring RPIA to muscle tip. The average RPIA diameter was 1.1mm and length was 36.4mm from the initial branching of the posterior interosseous artery. The average MCA diameter was 0.7mm. The posterior branch of the radial collateral artery was only found in 3/8 specimens. The RPIA and MCA were constant in all specimens. Dissection was safely carried to the border of the LE and olecranon without disruption of the MCA. CONCLUSIONS Our conclusions determined that if dissection of the anconeus is undertaken, the RPIA remains constant between the interval of the ECU as well as anconeus at an average distance of 18.3mm from the tip of the muscle measuring proximally; moreover, the MCA was constant in all specimens found directly between the LE and olecranon always running with the nerve to the anconeus. When dissecting and mobilizing to ensure preservation of the MCA, dissection should be taken from distal to proximal as well as dissecting along the ulnar border of the anconeus. Proximal dissection can be taken as proximal as the border of the LE and olecranon as that did not disrupt MCA blood supply.
