Review[Wrist arthrodesis with a fixed-angle, "low-profile" fusion plate without carpometacarpal joint fixation].
Total wrist arthrodesis to improve functional use of the hand by reducing pain and increasing grip strength. ⋯ Total wrist arthrodesis was performed using a fixed-angle fusion plate without CMC III joint fixation in 28 patients (21 men, 7 women). A follow-up of 14/28 patients was performed at a mean of 21 (3-39) months postoperatively. Grip strength improved from 14 (0-38) kg preoperatively to 22 (12-40) kg postoperatively. The average postoperative DASH score was 40 (6-72) points. Pain measured with the VAS scale (0-10) improved from an average of 7 (3-10) points preoperatively to 2 (0-6) points postoperatively. Overall, 13/14 patients were satisfied with the treatment; 26/28 patients achieved primary bony consolidation. Postoperative complications found in 9 of 28 patients: 2 nonunion, pain in the CMC II (n = 3) or III (n = 1) joints, 2 screw breakage, 1 postoperative bleeding and 1 infection. Both cases of nonunion healed after plate removal, re-osteosynthesis with a straight wrist arthrodesis plate, bridging the CMC III joint, and a bone graft from the iliac crest. All patients with CMC II joint pain were pain-free after removal of the protruding screw. One patient had chronic pain in the CMC III joint despite plate removal. In the 2 cases with screw breakage, no issues caused. In one patient, after primary bony consolidation, removal of the plate was performed for extensor tenolysis and not as a result of the broken screw. In the second patient, removal of the plate after primary bony consolidation was unnecessary as the patient was pain-free in the area of the broken screw, yet a protruding screw in the CMC II joint cavity was removed.

Review[Midcarpal partial arthrodesis with locking plate osteosynthesis].
Preservation of residual mobility and pain reduction in the wrist in advanced carpal collapse (scapholunate advanced collapse, SLAC or scaphoid nonunion advanced collapse, SNAC). ⋯ Complete consolidation of the bone in the X‑ray control in all 11 patients 12 weeks postoperatively. No implant-based complications. In one case a postoperative carpal tunnel syndrome had to be surgically treated. The postoperative extent of mobility showed overall satisfactory results with extension-flexion of 53° ± 18° (47% of the healthy side) and radial-ulnar abduction 30 ± 5° (58% of the healthy side). The postoperative values on the visual analog pain scale (VAS) were 0.7 ± 1.2 at rest and 4.3 ± 2.8 under load bearing. The gripping power was 19 ± 14 kg (56% of the non-operated side) and the disabilities of the arm, shoulder, hand (DASH) value was 33 ± 24.

[Open reduction and internal fixation of lateral tibial plateau fractures with free subchondral 2.7 mm screws].
Exact reconstruction of the depressed articular surface and stable subchondral fixation of the lateral tibial plateau (ORIF, "open reduction and internal fixation"). ⋯ Since February 2014, a total of 23 lateral tibial plateau fractures were treated using the described technique; 4 patients were lost to follow-up and the 3‑month follow-up of 2 patients is not completed yet. After an average of 167 days, 11 patients had no complaints. At approximately 3 months postoperatively, 10 patients had full range of motion, 3 had a flexion deficit of at least 30°, and 2 patients had residual instability of the medial collateral ligament. One postoperative superficial infection was noted. At the 3 month CT, 10 of 17 patients showed successful reduction without significant articular steps or anatomical malalignment.

[Correction of flexible lesser toe deformity : Transfer of the flexor digitorum longus tendon].
Realignment and pain relief of toes 2-5 by flexor-to-extensor tendon transfer of the flexor digitorum longus (FDL) muscle. ⋯ A total of 24 toes with flexible PIP and/or MTP joint deformity were treated with a FDL tendon transfer. In 14 toes an isolated procedure was performed, in 10 cases an additional metatarsal osteotomy. Patients with operative treatment of the first ray, revision or reoperation were excluded. Mean follow-up was 8.4 (4-14) months. After 6 weeks 22 toes (92%) showed physiological alignment of the PIP and MTP joint. At the last follow-up, 4 (16%) toes had recurrent or persistent extension deformity of the MTP joint. There were no infections, overcorrections, impaired wound healing or transversal malalignment.

Review[Corrective osteotomies for posttraumatic elbow deformities].
Correcion of elbow joint deformities that usually develop secondary to direct or indirect trauma of the arm or elbow with subsequent inadequate healing and consecutive axial/rotational malalignment and may be associated with cosmetic or functional deficits of the arm. ⋯ In general, the results for a three-dimensional osteotomy of the distal humerus are expected to be good to very good. Only in rare cases (2.5%) is a mostly transient irritation of the ulnar nerve observed.
