Comparative Study
Less is more: lag screw only fixation of lateral malleolar fractures.
Displaced fractures of the lateral malleolus are typically treated with plate osteosynthesis with or without the use of lag screws, and immobilisation in a plaster cast for up to 6 weeks. Fixation through a smaller incision with less metal, such as lag screw only fixation, would theoretically lead to decreased infection rates and less irritation caused by hardware. The purpose of this study was to evaluate the benefits and success of lag screw only fixation of the lateral malleolus in non-comminuted oblique fractures of the lateral malleolus. ⋯ Lag screw-only patients reported no palpable hardware as compared to 50% of the plate group. AOFAS scores at a mean of 12 months post-operative were similar in both groups. Lag screw only fixation of the lateral malleolus is a safe and effective method that has a number of advantages over plate osteosynthesis, in particular less soft tissue dissection, less prominent, symptomatic and palpable hardware and a reduced requirement for secondary surgical removal.

Facet joint pain is an important aspect of degenerative lumbar spine disease, and radiofrequency medial branch neurotomy remains an established therapy, while cryodenervation has still been poorly examined. This study was undertaken to examine the effects of medial branch cryodenervation in the treatment of lumbar facet joint pain. This was a prospective clinical case series. ⋯ Including failures, mean low back pain decreased significantly from 7.7 preoperatively to 3.2 at 6 weeks, 3.3 at 3 months, 3.0 at 6 months and 4.2 at 12 months (P<0.0001). Limitation of the activities of daily living improved parallel to reduced pain. Our results suggest that medial branch cryodenervation is a safe and effective treatment for lumbar facet joint pain.

Trapeziometacarpal osteoarthritis is a common entity, often bilateral and predominantly affecting postmenopausal women. In the case of failure of conservative treatment, surgery is a good option. The aim of this study was to compare three surgical procedures. 63 patients (74 thumbs) with osteoarthritis of the trapezio-metacarpal joint were surgically treated; 54 patients were seen for follow-up, 7 had died and 2 were lost to follow-up. ⋯ This study shows that the resection arthroplasty has equally good long term results compared to trapeziectomy combined with tendon interposition or arthrodesis. Resection arthroplasty is performed through a single incision and is technically simple. In our clinic resection arthroplasty is therefore the preferred technique for the treatment of osteoarthritis of the trapeziometacarpal joint.
