Anatomy of the hepatic hilar area: the plate system

To surgically manage hilar bile duct carcinoma successfully, it is important to be familiar with the principal anatomical variations of the biliary and vascular components of the plate system in the hepatic hilar area, because all the variations in the bile ducts and vessels occur in the plate system. The plate system consists of bile ducts and blood vessels surrounded by a sheath. There are three plates in the hilar area: the hilar plate, the cystic plate, and the umbilical plate. The bile duct and blood vessel branches penetrate the plate system and form Glisson's capsule in all segments of the liver, except for the medial segment. The right hepatic duct is usually (in 53%–72% of individuals) formed by the union of the anterior segmental duct and the posterior segmental duct in the hilar area. However, three other variations have been found in which these segmental ducts do not form the right hepatic duct. Few anatomical variations have been identified in the left hepatic duct, but confusion arises because of the variations in the medial segment ducts (B4) which join the left hepatic duct at different sites. In 35.5% of individuals they join the hepatic duct in the vicinity of the hilar confluence (type I B4 anatomy), and in 64.5% of individuals they join the left hepatic duct some distance away from the confluence (type II B4 anatomy). Because B4 is very close to the hilar confluence in type I, hilar bile duct carcinoma can easily invade B4 and, for that reason, for curative resection of hilar bile duct carcinoma, resection of S4a (the inferior part of the medial segment) should be considered along with the resection of extrahepatic bile duct and caudate lobe. Variations in the portal vein and hepatic artery are found in 16%–26% and 31%–33% of individuals, respectively. Because a considerable number of anatomical variations in the bile ducts and vessels persist in the hilar area, and the reported proportions of the different variations vary, it is necessary to have a good knowledge of the plate system and the variations in the bile ducts and blood vessels in the hilar area to perform safe and curative surgery for hilar bile duct carcinoma.

Biomechanical comparison of distal femoral fracture fixation: Analysis of non-locked,locked, and far-cortical locked constructs

To assess whether far-cortical locking (FCL) screws alter the fracture site strain environment and allow shorter bridge plate constructs for supracondylar femoral fractures, we tested the fracture site displacement under force of synthetic left femora with a 5-cm metaphyseal fracture gap, modeling comminution. Five models of nine constructs were tested (three types of diaphyseal screws [nonlocking, locking, and FCL] and two plate lengths [13 holes and 5 holes]). Long plate models using three or four diaphyseal screws (working length 13.5 or 7.5 cm, respectively) were compared with short plates with three diaphyseal screws (working length 7.5 cm). Models were loaded axially and torsionally; 100 cycles in random order. Primary outcome measures were axial and torsional fracture site stiffness. FCL screws decreased rotational stiffness 19% (P < .01) compared with baseline nonlocking screws in the same plate and working length construct, mirroring the effect (20% decrease in stiffness, P < .01) of nearly doubling the nonlocking construct working length (7.5-13.5 cm). Similarly, FCL screws decreased axial stiffness 23% (P < .01) in the same baseline comparison. Fracture site displacement under loading comparable to a long working length nonlocked plate construct was achieved using a shorter FCL plate construct. By closely replicating the biomechanical properties of a long plate construct, a fracture site strain environment considered favorable in promoting fracture healing might still be achievable using a shorter plate length. Clinical Significance: It might be possible to optimize fracture site strain environment and displacement under loading using shorter FCL plate constructs.

Immunolocalization of the angiogenetic factor pleiotrophin (PTN) in the growth plate of mice

The aim of this study was to find out whether and where the angiogenic agent pleiotrophin (PTN) occurs within the growth plate. We investigated paraffin-embedded tissue sections of ten male mice with an antibody directed against the recombinant PTN. Immunostaining for PTN was positive within the cytoplasm and the pericellular matrix of osteoblasts which lined the longitudinal mineralized septae of the epiphyseal plate. Within the zone of hypertrophic chondrocytes, immunolabelling for PTN was positive in the pericellular matrix of hypertrophic chondrocytes and within the opened lacunae of the apoptotic hypertrophic chondrocytes. The resting zone and the proliferation zone were PTN negative. The results of our study suggest that the known angiogenetic peptide PTN plays a role in the process of angiogenesis in the growth plate. Received: 17 November 1999

Comparison of the efficacy of a distal clavicular locking plate versus a clavicular hook plate in the treatment of unstable distal clavicle fractures and a systematic literature review

Purpose

The purpose of this study was to retrospectively compare and review the clinical outcomes between the distal clavicular locking plate and clavicular hook plates in the treatment of unstable distal clavicle fractures; moreover, the relevant literature of the two fixation methods was reviewed systematically to identify the non-union, complications, or functional scores, according to the treatment methods and determine which treatment method is better.

Methods

Sixty-six patients with 66 unstable distal clavicle fractures who underwent open reduction and internal fixation with either a distal clavicular locking plate (36 patients) or a clavicular hook plate (30 patients ) were evaluated. The main outcome comparisons included Constant score, rate of non-union, rate of complication, and rate of returning to work three months postoperatively.

Results

No significant difference was found between locking plate and hook plate groups in union rate and Constant score (P > 0.05). However, the results indicated that the distal clavicular locking plate group had a significantly lower rate of complications (P < 0.05) and symptomatic hardware (P < 0.05). In addition, the distal clavicular locking plate facilitated the return to work better than the clavicular hook plate (P < 0.05).

Conclusions

Both distal clavicular locking plate and clavicular hook plate achieved good results in the treatment of unstable distal clavicle fractures; however, internal fixation with a distal clavicular locking plate had greater ability to return to their previous work after surgery in three months and fewer complications than the clavicular hook plate.
