RESUMEN
OBJECTIVES: The purpose of this study was to assess the need of bone graft or bone substitutes in unstable distal radius fractures (DRF) treated with locking compression plates (LCP) PATIENTS AND METHODS: An observational and prospective study was conducted on 60 patients with DRF AO-type A3 and AO-type C3, treated surgically by LCP plates without bone grafts or substitutes. Ranges of motion in flexion (F), extension (E), pronation (P), and supination (S) were measured in the injured wrist and compared with the healthy contralateral wrist. X-ray parameters: palmar tilt (PT), radial inclination (RI), ulnar variance (UV), and radial height (RH) were calculated in the injured wrist one year after surgery and then compared, with those parameters in the healthy contralateral wrist and in the follow-up postoperative x-ray of the injured wrist. PRWE and DASH scores were used to evaluate patient satisfaction. RESULTS: The range of motion loss was F 12° ± 16.1°, E 9° ± 13.1°, P 2.5° ± 7.5°, and S 5°±10°, but they remained within functional parameters. Good results were also obtained in the PRWE and DASH scores (DASH 12.6 ± 14.16 and PRWE 9.5 ± 9.5). All the fractures were healed without significant collapse (IP 0.55 ± 1.7°, IR 0.31 ± 1.5°, VC 0.25±0.8mm, and AR 0.1 ± 0.9 mm). CONCLUSIONS: All fractures healed without problems or with significant loss of reduction. Bone graft and bone substitutes are not mandatory for treatment of unstable DRF with LCP plates. Their use increases the cost and is not exempt of morbidities. This study also reinforces the role of LCP plates in surgical treatment of unstable DRF.

Mucormycosis is a highly aggressive fungal infection caused by Zygomycetes, from the order of Mucorales. This infection commonly presents an aggressive and rapid course and typically affects immunocompromised patients. Mucormycosis can manifest in different clinical patterns and locations. Although the correct diagnosis is often difficult, an early identification is essential for patient survival. Several clinical forms of mucormycosis are recognised. Cutaneous mucormycosis is less common than other clinical forms, but potentially lethal if treatment is not rapid. Tissue examination by histopathology and culture confirms the fungal infection. Standard treatment includes antifungal therapies associated with surgical debridement. We report five different cases of cutaneous mucormycosis treated in our institution and the management carried out in each case.

UNLABELLED: We present an anatomical study that describes the distribution of the cutaneous perforators (CP) of both heads of the biceps femoris muscle. MATERIAL AND METHODS: In this study, we dissected 18 legs from nine cadavers. The study was centered on the biceps femoris muscle and musculocutaneous perforator arteries from both muscular heads. Only perforator arteries with comitant vein diameters of over 0.5 mm were selected. The vascular origin and length were also studied. In all cases, measurements were taken from the bicondyle line. RESULTS: The measurements taken from the muscle bellies of the biceps gave the following results; for the long head 33.91 cm as medium length (SD = 2.70) and for the short head 23.85 cm as medium length (SD = 2.96). The total number of perforator arteries obtained from the two muscle bellies was 139, with the greatest percentage located in the lower half of the thigh. The majority follow an intramuscular route (80.48%) and less frequently they are septals (19.52%). The lengths of perforator arteries from its origin in the axial vessel of the muscle to the subcutaneous fat were, for the short head 5.01+/-1.33 (3.0-10.0), whereas the same measurement, in the long head was 4.54+/-1.36 (2.5-9.0). The principal vascular origin of the perforator arteries was the popliteal artery in both muscle bellies, whilst the second arterial vessel in importance was the first and second profunda perforator artery. CONCLUSION: From the results obtained in our work, we can deduce that it is always possible to locate perforator arteries in both muscle bellies; most frequently they have intramuscular distribution and are located in the proximity of the vascular septum. Their most common origins are the popliteal artery and first and second profunda perforator artery. Finally, it is possible to design pedicle and free flaps, with less morbidity and more versatility than musculocutaneous flaps.

The medial sural artery supplies the medial gastrocnemius muscle and sends perforating branches to the skin. The possible use of these musculocutaneous perforators as the source of a perforator-based free flap was investigated in cadavers. Ten legs were dissected, and the topography of significant perforating musculocutaneous vessels on both the medial and the lateral gastrocnemius muscles was recorded. A mean of 2.2 perforators (range, 1 to 4) was noted over the medial gastrocnemius muscle, whereas in only 20 percent of the specimens was a perforator of moderate size noted over the lateral gastrocnemius muscle. The perforating vessels from the medial sural artery clustered about 9 to 18 cm from the popliteal crease. When two perforators were present (the most frequent case), the perforators were located at a mean of 11.8 cm (range, 8.5 to 15 cm) and 17 cm (range, 15 to 19 cm) from the popliteal crease. A series of six successful clinical cases is reported, including five free flaps and one pedicled flap for ipsilateral lower-leg and foot reconstruction. The dissection is somewhat tedious, but the vascular pedicle can be considerably long and of suitable caliber. Donor-site morbidity was minimal because the muscle was not included in the flap. Although the present series is short, it seems that the medial sural artery perforator flap can be a useful flap for free and pedicled transfer in lower-limb reconstruction.
