Management of Index Finger Metacarpophalangeal Joint Arthritis.

Metacarpophalangeal joint arthritis of the index finger is a debilitating disease often caused by osteoarthritis or inflammatory arthritides such as rheumatoid arthritis. Treatment options include nonsurgical management with nonsteroidal anti-inflammatory drugs, splinting, occupational therapy, corticosteroid injections, and disease-modifying antirheumatic drugs. Operative management options include arthrodesis and arthroplasty, which can be further broken down into silicone implants and 2 component resurfacing implants. The article summarizes the current literature for each of the treatment options for metacarpophalangeal joint arthritis of the index finger.

A Comparative Analysis of Local Anesthetics: Injection Associated Pain and Duration of Anesthesia.

BACKGROUND: Local anesthesia administration is frequently the most painful step of dermatologic surgery. Identification of an anesthetic that minimizes infiltration pain and toxicity while maximizing duration of action would improve both patient satisfaction and procedural safety. This study compared eight local anesthetic solutions to identify the composition that minimizes infiltration pain, maximizes duration of effect, and minimizes amount of local anesthetic needed. METHODS: In a double-blinded study, thirty subjects were injected with eight local anesthetic solutions of varied concentrations of lidocaine, epinephrine, benzyl alcohol, and sodium bicarbonate. Infiltration pain was rated by subjects using a visual analog scale and duration of anesthesia was assessed by needle prick sensation every 15 minutes. RESULTS: Solutions 2, 7, and 8, were significantly less painful (P<0.001), though not statistically different from each other. Two of the three solutions were buffered 10:1 with sodium bicarbonate. Additionally, two of the three contained notably decreased concentrations of lidocaine, 0.091% and 0.083%, than traditionally used in practice. The use of benzyl alcohol did not result in a reduction of reported pain. The duration of action was equal among the solutions regardless of anesthetic concentration. CONCLUSIONS: A solution of 0.091% lidocaine with epinephrine 1:1,100,000 and 0.82% benzyl alcohol reduces medication dose while ensuring maximum patient comfort and, theoretically, increases shelf life. While considered off-label, clinically effective dermal anesthesia may be obtained at a lower concentration of lidocaine and epinephrine than is commonly used, aiding conservative use of local anesthetic, particularly during times of national shortage.

Contemporary Review: Autograft Bone Use in Foot and Ankle Surgery.

Bone autografts are frequently harvested for use in foot and ankle surgery. A commonly used harvest site is the iliac crest; however, because of known morbidity with this site, the tibia and calcaneus are attractive alternatives. There remains limited understanding regarding the osteogenic potential of autografts from each of these locations. In this review, we provided an update of the known data on bone autografts from the iliac crest, tibia, and calcaneus, focusing on the total cells harvested from each site as well as the presence of osteogenic osteoprogenitor cells. Level of Evidence: Level V, expert opinion.

Routine immediate postoperative radiographs rarely identify unknown complications after shoulder arthroplasty.

BACKGROUND: Intraoperative complications after shoulder arthroplasty (SA) are uncommon, yet surgeons continue to obtain immediate postoperative radiographs despite prior literature questioning the efficacy of these images. There is a paucity of literature describing the role of immediate postoperative radiographs in revision SA. This study aimed to evaluate the utility of immediate postoperative radiographs in identifying intraoperative complications leading to a change in care after primary or revision SA. We hypothesized that routine postoperative ("survey") radiographs would not provide a high diagnostic yield in identifying early complications requiring a change in postoperative management. METHODS: A retrospective review of 4063 SAs (1298 primary anatomic total shoulder arthroplasties [aTSAs], 2162 primary reverse shoulder arthroplasties [RSAs], 129 revision aTSAs, and 474 revision RSAs) was performed from a multi-institutional arthroplasty database. All shoulders were evaluated with a single immediate postoperative (survey) radiograph that was read by a musculoskeletal radiologist and by the treating orthopedic surgery team. The radiology reports of all 4063 immediate postoperative radiographs were reviewed to determine whether complications had been identified. For patients in whom complications were identified, the medical record was then reviewed to determine whether the survey radiograph resulted in a return to the operating room or a change in management between the surgical procedure and the first postoperative clinic visit with radiographic evaluation. RESULTS: Complications were reported by a radiologist on the basis of immediate postoperative radiographs in 10 of 4063 shoulders (0.2%, or 1 of every 500 arthroplasties). Complications were reported after 4 primary RSAs, 4 revision aTSAs, and 2 revision RSAs; no complication was reported after any of the primary aTSAs. Of the 10 complications, only 3 were unknown to the treating surgeon following the operation and none altered immediate postoperative management. Early complications were reported at a rate of 1% after revision arthroplasty vs. 0.1% after primary arthroplasty (P = .001). Additionally, revision aTSA was found to have a higher rate of complications reported on radiographs, with a rate of 3.1%, compared with revision RSA, at 0.4% (P = .021). CONCLUSION: The radiology reports of routine immediate postoperative radiographs rarely identified postoperative complications (0.2%). In all cases, postoperative management remained unaltered until the time of the first postoperative visit. The value and medicolegal implications of immediate postoperative radiographs may inform the decision to abandon obtaining these studies routinely.
